Description of Business

Description of Business	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business DraftKings Inc., a Nevada corporation (the “Company” or “DraftKings”), was incorporated in Nevada as DEAC NV Merger Corp., a wholly owned subsidiary of our legal predecessor, Diamond Eagle Acquisition Corp. (“DEAC”), a special purpose acquisition company. On April 23, 2020, DEAC consummated the transactions contemplated by the Business Combination Agreement (the “Business Combination”) dated December 22, 2019, as amended on April 7, 2020 and, in connection therewith, (i) DEAC merged with and into the Company, whereby the Company survived the merger and became the successor issuer to DEAC by operation of Rule 12g-3(a) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (ii) the Company changed its name to “DraftKings Inc.,” (iii) the Company acquired DraftKings Inc., a Delaware corporation (“Old DK”), by way of a merger and (iv) the Company acquired all of the issued and outstanding share capital of SBTech (Global) Limited (“SBTech”). Upon consummation of the preceding transactions, Old DK and SBTech became wholly owned subsidiaries of the Company. DraftKings is a digital sports entertainment and gaming company. The Company’s business-to-consumer (“B2C”) segment provides users with daily fantasy sports (“DFS”), sports betting (“Sportsbook”) and online casino (“iGaming”) products, as well as media and other online consumer product offerings. The Company’s business-to-business (“B2B”) segment is involved in the design, development and licensing of sports betting and casino gaming software for its Sportsbook and casino gaming products. In May 2018, the Supreme Court (the “Court”) struck down on constitutional grounds the Professional and Amateur Sports Protection Act of 1992 (“PASPA”), a law that prohibited most states from authorizing and regulating sports betting. Since the Court’s decision, many states have legalized sports betting. As of December 31, 2021, 29 U.S. states, the District of Columbia and Puerto Rico have legalized some form of sports betting. Of those 31 legal jurisdictions, 23 have legalized online sports betting. Of those 23 jurisdictions, 18 are live, and DraftKings operates in 15 of them. The jurisdictions with statutes legalizing iGaming are Connecticut, Delaware, Michigan, New Jersey, Pennsylvania and West Virginia. As of December 31, 2021, the Company operates online Sportsbooks in Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Michigan, New Hampshire, New Jersey, Oregon (B2B), Pennsylvania, Tennessee, Virginia, West Virginia and Wyoming and has retail Sportsbooks in Colorado, Connecticut, Illinois, Iowa, Louisiana, Mississippi, New Hampshire, New Jersey and New York. As of December 31, 2021, the Company offers iGaming products in Connecticut, Michigan, New Jersey, Pennsylvania and West Virginia. The Company also has arrangements in place with land-based casinos to expand operations into additional states upon the passing of relevant legislation, the issuance of related regulations and the receipt of required licenses. The novel coronavirus (“COVID-19”) has adversely impacted global commercial activity, disrupted supply chains and contributed to significant volatility in financial markets. Beginning in 2020 and continuing into 2021, the COVID-19 pandemic adversely impacted many different industries. The ongoing COVID-19 pandemic, including the emergence of new variants or strains of COVID-19, could have a continued material adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the extent and the duration of the impact of COVID-19. The COVID-19 pandemic therefore presents material uncertainty and risk with respect to us and our performance and could affect our financial results in a materially adverse way. Since the start of the COVID-19 pandemic, the primary impacts to the Company have been the suspension, cancellation and rescheduling of sports seasons and sporting events. Beginning in March 2020 and continuing into the first month of the third quarter of 2020, many sports seasons and sporting events, including the MLB regular season, domestic soccer leagues and European Cup competitions, the NBA regular season and playoffs, the NCAA college basketball tournament, the Masters golf tournament, and the NHL regular season and playoffs, were suspended or cancelled. Starting in the third quarter of 2020 and continuing into the fourth quarter of 2020, major professional sports leagues resumed their activities, many of which were held at limited or reduced capacity. MLB began its season after a three-month delay and also completed the World Series, the NHL resumed its season and completed the Stanley Cup Playoffs, the Masters golf tournament was held, most domestic soccer leagues resumed and several European cup competitions were held, and the NFL season began on its regular schedule. During this period, the NBA also resumed its season, completed the NBA Finals and commenced its 2020-2021 season. The suspension and alteration of sports seasons and sporting events in 2020 reduced customers’ use of, and spending on, the Company’s Sportsbook and DFS product offerings and caused the Company to issue refunds for canceled events. In the year ended December 31, 2021, many sports seasons continued and most sporting events were held as planned (including sporting events postponed from 2020), including the NFL regular season, the NFL Playoffs and Superbowl LV, MLB regular season and the World Series, the NBA regular season and NBA playoffs, the NHL regular season and the NHL Stanley Cup, the NASCAR Cup Series, various NCAA football bowl games, the NCAA college basketball season and tournament, and the UEFA European Football Championship. The return of major sports and sporting events generated significant user interest and activity in our Sportsbook and DFS product offerings. However, the possibility remains that sports seasons and sporting events may be suspended, cancelled or rescheduled due to COVID-19 outbreaks. The Company’s revenue varies based on sports seasons and sporting events amongst other factors, and cancellations, suspensions or alterations resulting from COVID-19 have the potential to adversely affect its revenue, possibly materially. However, the Company’s product offerings that do not rely on sports seasons and sporting events, such as iGaming, may partially offset this adverse impact on revenue. A significant or prolonged decrease in consumer spending on entertainment or leisure activities would also likely have an adverse effect on demand for the Company’s product offerings, reducing cash flows and revenues, and thereby materially harming the Company’s business, financial condition and results of operations. In addition, a materially disruptive resurgence of COVID-19 cases or the emergence of additional variants or strains of COVID-19 could cause other widespread or more severe impacts depending on where infection rates are highest. As steps taken to mitigate the spread of COVID-19 necessitated a shift away from a traditional office environment for many employees, the Company implemented business continuity programs to ensure that employees were safe and that the business continued to function with minimal disruptions to normal work operations while employees worked remotely. The Company will continue to monitor developments relating to disruptions and uncertainties caused by COVID-19.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Practices	Summary of Significant Accounting Policies and Practices Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts and operations of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions are eliminated upon consolidation. Certain amounts, which are not material, in the prior years’ consolidated financial statements have been reclassified to conform to the current year presentation. Pursuant to the Business Combination, the merger between a subsidiary of DEAC and Old DK was accounted for as a reverse recapitalization in accordance with U.S. GAAP (the “Reverse Recapitalization”). Under this method of accounting, DEAC was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Old DK issuing stock for the net assets of DEAC, accompanied by a recapitalization. The net assets of DEAC are stated at historical cost, with no goodwill or other intangible assets recorded. The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization are those of Old DK. The shares and corresponding capital amounts and earnings per share available for common stockholders, prior to the Business Combination, have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination. Further, Old DK was determined to be the accounting acquirer in the SBTech Acquisition, as such, the acquisition is considered a business combination under Accounting Standards Codification (“ASC”), Topic 805, Business Combinations , (“ASC 805”) and was accounted for using the acquisition method of accounting. DraftKings recorded the fair value of assets acquired and liabilities assumed from SBTech. The presented financial information for the year ended December 31, 2020 includes the financial information and activities for SBTech for the period from April 24, 2020 to (and including) December 31, 2020. Prior to the second quarter of 2021, the Company (a) included changes in “cash reserved for users” as a component within the change in operating assets and liabilities on its condensed consolidated statement of cash flows as the Company historically viewed the change in cash reserved for users as offsetting the change in player liabilities and (b) presented “cash reserved for users” separate from cash and cash equivalents on the condensed consolidated balance sheet. Beginning with the second quarter of 2021, to reflect the Company's total cash position (“cash and cash equivalents” and “cash reserved for users”) and to conform to Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows (Topic 230) — Restricted Cash , the Company revised its presentation to exclude changes in “cash reserved for users” from the “change in operating assets and liabilities” and instead present the total balance as a component of cash and cash equivalents and restricted cash on its condensed consolidated statement of cash flows. This revision does not have a material impact on the Company's presentation of cash flows as the change in cash reserved for users will continue to be presented as a supplemental disclosure in the consolidated statement of cash flows. In addition, the Company will continue to present cash reserved for users as a separate line item on the Company’s condensed consolidated balance sheet. These revisions have no impact on the Company’s previously reported consolidated statements of operations or consolidated balance sheets, including the Company’s cash and cash equivalents and cash reserved for user balances. Prior period amounts have been revised to conform to the current period presentation. The following table presents the consolidated statement of cash flows line items after giving effect to the revision of presentation as discussed above for 2020 and 2019. Year ended December 31, 2020 Year ended December 31, 2019 Reported Adjustments Revised Reported Adjustments Revised Adjustments to reconcile net loss to net cash flows used in operating activities: Change in operating assets and liabilities, net of effect of business combinations: Cash reserved for users $ (143,718) $ 143,718 $ — $ (32,302) $ 32,302 $ — Net cash flows used in operating activities (337,875) 143,718 (194,157) (78,880) 32,302 (46,578) Net increase (decrease) in cash, cash equivalents and restricted cash 1,740,725 143,718 1,884,443 (41,375) 32,302 (9,073) Cash and cash equivalents and restricted cash at the beginning of period 76,533 144,000 (a) 220,533 117,908 111,698 (b) 229,606 Cash and cash equivalents and restricted cash, end of period $ 1,817,258 $ 287,718 $ 2,104,976 $ 76,533 $ 144,000 $ 220,533 (a) Represents the cash reserved for user balance as of December 31, 2019 as previously included in the Company's 2020 Annual Report filed with the SEC. (b) Represents the cash reserved for user balance as of December 31, 2018 as previously included in the Company's Form S-1 filed with the SEC on October 6, 2020. Comprehensive Loss Comprehensive loss consists of foreign currency translation adjustments related to the effect of foreign exchange on the value of our assets and liabilities denominated in Euros. The translation gain or loss is included in the consolidated statements of comprehensive loss. Foreign Currency Our reporting currency is the U.S. dollar while the functional currency of the Company’s significant non-U.S. subsidiaries is the Euro. The financial statements of the Company’s significant non-U.S. subsidiaries are translated into United States dollars in accordance with ASC 830, Foreign Currency Matters , using period-end rates of exchange for assets and liabilities, and average rates of exchange for the period for revenues, costs and expenses and historical rates for equity. During 2021, 2020 and 2019, foreign currency transactions did not significantly impact net income. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions reflected in the financial statements relate to and include, but are not limited to, the valuation and expensing of equity awards, accounting for contingencies and uncertainties, purchase price allocations, including fair value estimates of intangible assets, the estimated useful lives of fixed assets and intangible assets, internally developed software costs and accrued expenses. Going Concern Based on anticipated spend and cash received from the Business Combination, exercise of certain warrants, the June 2020 and October 2020 follow-on equity offerings, the issuance of convertible notes in March 2021 and the timing of expenditure assumptions, the Company currently expects that its cash will be sufficient to fund its operating expenses and capital expenditure requirements for at least 12 months after February 18, 2022. The Company has experienced operating losses and negative operating cash flows for the years ended December 31, 2021, 2020 and 2019. While certain geographies may experience improved cash flow, the Company expects to continue to incur annual operating losses and annual negative operating cash flow for the foreseeable future. Concentration Risks and Uncertainties Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of operating cash and cash equivalents and cash reserved for users. The Company maintains separate accounts for cash and cash reserved for users primarily across four financial institutions. Some amounts exceed federally insured limits with the majority of cash held in one financial institution. Management believes all financial institutions holding its cash are of high credit quality and does not believe the Company is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. The Company relies on a limited number of vendors to support operations. In particular, a single vendor is currently the primary provider of web services that allows the Company to host its sports betting, iGaming and daily fantasy sports offerings. Any interruption in the services provided by this supplier could have a material adverse effect on its business, financial condition and results of operations. The Company's growth prospects and market potential will depend on its ability to obtain and maintain licenses to operate in a number of jurisdictions and if the Company fails to obtain and maintain such licenses its business, financial condition, results of operations and prospects could be impaired. Business Combinations The Company accounts for business combinations under the acquisition method of accounting, in accordance with ASC 805, which requires assets acquired and liabilities assumed to be recognized at their fair values as of the acquisition date. Any fair value of purchase consideration in excess of the fair value of the assets acquired less liabilities assumed is recorded as goodwill. The fair values of the assets acquired and liabilities assumed are determined based upon the valuation of the acquired business and involve management making significant estimates and assumptions. Cash and cash equivalents Cash and cash equivalents consist of highly liquid, unrestricted savings, money market funds, checking and other bank accounts. Cash Reserved for Users The Company maintains separate bank accounts to segregate users’ funds from operational funds. In certain regulated jurisdictions, user funds are held by DK Player Reserve, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company, which was organized for the purpose of protecting users’ funds in the event of creditor claims. Receivables Reserved for Users Receivables for user deposits not yet received are stated at the amount the Company expects to collect from a payment processor, which includes an allowance for credit losses if appropriate. These receivables arise, primarily, due to process timing between when a user deposits and when the Company receives that deposit from the payment processor. Receivables also arise due to the securitization policies of certain payment processors. The allowance for credit losses is determined based on the Company’s assessment of the probability of the non-payment of the receivable. This provision is netted against the receivable balance with the loss being recognized within general and administrative expenses in the consolidated statements of operations. The provision at December 31, 2021 and December 31, 2020 did not have a material impact on the Company’s consolidated financial statements. Accounts Receivables Accounts receivables are recorded at amortized cost, less any allowance for credit losses. The allowance for credit losses is determined based on the Company’s assessment of the probability of non-payment of the receivable. This provision is netted against the receivable balance with the loss being recognized within general and administrative expenses in the consolidated statements of operations. The provision at December 31, 2021 and December 31, 2020 did not have a material impact on the Company’s consolidated financial statements. Property and Equipment, Net Property and equipment are carried at cost, net of accumulated depreciation. Depreciation is computed utilizing the straight-line method over the estimated useful life of the asset. Leasehold improvements depreciation is computed over the shorter of the lease term or estimated useful life of the asset. Additions and improvements are capitalized, while repairs and maintenance are expensed as incurred. Useful lives of each asset class are generally as follows: Computer equipment and software 3 years Furniture and fixtures 7 years Leasehold improvements Lesser of the lease terms or the estimated useful lives of the improvements, generally 1–10 years Intangible Assets, Net The Company’s intangible assets consist of developed technology, customer relationships, internally-developed software, gaming licenses, trademarks and tradenames and digital assets. The related amortization expense is classified as cost of revenue in the consolidated statements of operations. Estimates and assumptions that we must make in estimating the fair value of future acquired technology, user lists and other identifiable intangible assets include future cash flows that we expect to generate from the acquired assets. Developed Technology Developed technology primarily relates to the design and development of sports betting and casino gaming software for online and retail sportsbook and casino gaming products acquired from SBTech and other acquisitions and recorded at fair value at the date of acquisition. Customer Relationships Customer (or “user”) relationships are finite-lived intangible assets which are amortized over their estimated economic lives. Customer relationships are generally recognized as the result of business combinations. Internally Developed Software Software that is developed for internal use is accounted for pursuant to ASC 350-40, Intangibles, Goodwill and Other—Internal-Use Software . Qualifying costs incurred to develop internal-use software are capitalized when (i) the preliminary project stage is completed, (ii) management has authorized further funding for the completion of the project and (iii) it is probable that the project will be completed and perform as intended. These capitalized costs include compensation for employees who develop internal-use software and external costs related to development of internal use software. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Internally developed software is amortized using the straight-line method over an estimated useful life. All other expenditures, including those incurred in order to maintain an intangible asset’s current level of performance, are expensed as incurred. Gaming Licenses The Company incurs fees in connection with applying for and maintaining good standing in jurisdictions via business licenses. Fees incurred in connection with the application and subsequent renewals are capitalized and amortized using the straight-line method over an estimated useful life. In certain arrangements, the Company enters into agreements to operate on a business partner’s license in exchange for upfront fees. These fees are capitalized and amortized over the shorter of their expected benefit under the partnership agreement or estimated useful life. Trademarks and Tradenames The Company incurs fees in connection with applying for and maintaining trademarks and tradenames as well as trademarks and tradenames resulting from acquisitions. Fees incurred in connection with the application and subsequent renewals are capitalized and amortized using the straight-line method over an estimated useful life. Digital Assets The Company has purchased certain digital assets, including crypto currencies, with cash that is not required to currently support its operations. The Company accounts for digital assets in accordance with ASC 350, Intangibles—Goodwill and Other (Topic 350). Accordingly, if the fair market value at any point during the reporting period is lower than the carrying value an impairment loss equal to the difference will be recognized in the consolidated statement of operations. If the fair market value at any point during the reporting period is higher than the carrying value the basis of the digital assets will not be adjusted to account for this increase. Gains on digital assets, if any, will be recognized upon sale or disposal of the assets. Impairment of Long-Lived Assets Long-lived assets, except for goodwill, consist of property and equipment and finite-lived acquired intangible assets, such as internal-use software, developed software, gaming licenses, trademarks, tradenames and customer relationships. Long-lived assets, except for goodwill, are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the asset may not be fully recoverable. Impairment expense is recognized to the extent an asset’s expected undiscounted future cash flows are less than the asset’s carrying amount. The Company determined that long-lived assets were not significantly impaired 2021, 2020 or 2019. Goodwill The Company’s business is classified into three reporting units: B2C, Media and B2B. In testing goodwill for impairment, the Company has the option to begin with a qualitative assessment, commonly referred to as “Step 0,” to determine whether it is more likely than not that the fair value of a reporting unit containing goodwill is less than its carrying value. This qualitative assessment may include, but is not limited to, reviewing factors such as macroeconomic conditions, industry and market considerations, cost factors, entity-specific financial performance and other events, such as changes in the Company’s management, strategy and primary user base. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative goodwill impairment analysis by comparing the carrying amount to the fair value of the reporting unit. If the carrying amount exceeds the fair value, goodwill will be written down to the fair value and recorded as impairment expense in the consolidated statements of operations. The Company performs its impairment testing annually and when circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company performed its annual impairment assessment of goodwill as of October 1, 2021 and concluded that goodwill was not impaired. Equity Method Investment The Company has a 49.9% membership interest in DKFS, LLC, also known as DRIVE by DraftKings as of December 31, 2021. In addition, the Company has committed to invest up to $17.5 million into DBDK Venture Fund I, LP, a Delaware limited partnership and a subsidiary of DKFS LLC. As of December 31, 2021, the Company had invested a total of $3.5 million of the total commitment, which represents ownership of approximately 28.6% in the fund. The Company uses the equity method to account for investments in which the Company has the ability to exercise significant influence over the operating and financial policies of the investee, but does not exercise control and is not the primary beneficiary. The Company’s judgment regarding its level of influence over the equity method investee includes considering key factors, such as ownership interest, representation on the board of directors, and participation in policy-making decisions. The Company’s carrying value in the equity method investee is reflected in the caption “Equity method investment” on the consolidated balance sheets. Changes in value of DKFS, LLC and DBDK Venture Fund I, LP are recorded in “(Gain) Loss from equity method investment” on the consolidated statements of operations. Under the equity method, the Company’s investment is initially measured at cost and subsequently increased or decreased to recognize the Company’s share of income and losses of the investee, capital contributions and distributions and impairment losses. The Company performs a qualitative assessment annually and recognizes an impairment if there are sufficient indicators that the fair value of the investment is less than carrying value. Leases The Company leases certain office spaces, equipment and vehicles and recognizes lease expense on a straight-line basis over the initial term of the lease unless external economic factors exist such that renewals are reasonably certain. In those instances, the renewal period would be included in the lease term to determine the period in which to recognize the lease expense. Leases for periods through December 31, 2019 were reported under ASC 840, Leases (Topic 840) (“ASC 840”), including the disclosure requirements. The Company recognizes rent expense on operating leases on a straight-line basis over the non-cancellable lease term. Operating leases with landlord-funded leasehold improvements are considered tenant allowances and are amortized as a reduction of rent expense over the non-cancellable lease term. Deferred rent liability, which is calculated as the difference between contractual lease payments and the rent expense, is recorded in accounts payable and accrued expenses and other long-term liabilities in the consolidated balance sheets. The Company adopted Accounting Standards Update (“ASU”) 2016-2, Leases (Topic 842) (“ASU 2016-2”), using the alternative transition method provided in ASU 2018-11, Leases (Topic 842) (“ASU 2018-11”): Targeted Improvements as of January 1, 2020 at December 31, 2020. Using the alternative transition method, the Company applied the transition requirements at the effective date of ASU 2016-2. The Company elected the package of practical expedients permitted under the transition guidance within the new lease standard. In addition, the Company has elected to apply the practical expedient to combine lease and related non-lease components, for all classes of underlying assets, and account for the combined contract as a lease component, as well as the election was made to apply the short-term lease recognition exemption. Warrant Liabilities As part of DEAC’s initial public offering on May 14, 2019, DEAC issued 13.3 million warrants where each whole warrant entitles the holder to purchase one share of Class A common stock at an exercise price of $11.50 per share (the “Public Warrants”). Simultaneously with the closing of the IPO, DEAC completed the private sale of 6.3 million warrants to DEAC’s sponsor at a purchase price of $1.50 per warrant (the “Private Warrants”). Each Private Warrant allows the sponsor to purchase one share of Class A common stock at $11.50 per share. The Private Warrants and the shares of common stock issuable upon the exercise of the Private Warrants are not transferable, assignable or salable until after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Warrants are exercisable for cash or on a cashless basis, at the holder’s option, and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrant. The Company classified the Warrants pursuant to ASC 815 as derivative liabilities with subsequent changes in their respective fair values recognized in the consolidated statement of operations at each reporting date. Liabilities to Users The Company records liabilities for user account balances. User account balances consist of user deposits, most promotional awards and user winnings less user withdrawals, tax withholdings and user losses. Cash reserved for users and receivables reserved for users equal or exceed the Company’s liabilities to users at all times. Loss Contingencies The Company’s loss contingencies, which are included within other long-term liabilities in the consolidated balance sheets, are uncertain by nature and their estimation requires significant management judgment as to the probability of loss and estimation of the amount of such loss. These contingencies include, but may not be limited to, indirect taxes, regulatory investigations and proceedings and management’s evaluation of complex laws and regulations, and the extent to which they may apply to our business and industry. The Company regularly reviews its contingencies to determine whether the likelihood of loss is probable and to assess whether a reasonable estimate of the loss can be made. Determination of whether a loss estimate can be made is a complex undertaking that considers the judgement of management, third-party research, the prospect of negotiation and interpretations by regulators and courts, among other information. When a loss is determined to be probable, and the amount of the loss can be reasonably estimated, an estimated contingent liability is recorded. Revenue Recognition Effective January 1, 2019, the Company adopted ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), using the modified retrospective method for all contracts not completed as of the date of adoption. ASC 606 requires companies to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the standard requires more detailed disclosures to enable readers of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The cumulative effect of the adoption was immaterial to the consolidated financial statements. See Note 10 – Revenue Recognition for further details. The Company determines revenue recognition through the following steps: • Identify the contract, or contracts, with the customer; • Identify the performance obligations in the contract; • Determine the transaction price; • Allocate the transaction price to performance obligations in the contract; and • Recognize revenue when, or as, the Company satisfies performance obligations by transferring the promised good or services. The Company is currently engaged in the business of digital sports entertainment and gaming and provides its users with online gaming opportunities. The Company also provides online sportsbook and casino operators with technical infrastructure as well as related services with respect to its direct customers and distributors. The following is a description of the Company’s revenue streams: Online Gaming DFS is a peer-to-peer product in which users compete against one another for prizes. Users pay an entry fee to join a DFS contest and compete for prizes, which are distributed to the highest performing competitors in each contest as defined by each contest’s prize table. DFS revenue is generated from contest entry fees from users, net of prizes and customer incentives awarded to users. Sportsbook or sports betting involves a user wagering money on an outcome or series of outcomes occurring. When a user’s wager wins, the Company pays the user a pre-determined amount known as fixed odds. Sportsbook revenue is generated by setting odds such that there is a built-in theoretical margin in each sports wagering opportunity offered to users. Sportsbook revenue is generated from users’ wagers net of payouts made on users’ winning wagers and incentives awarded to users. iGaming, or online casino, typically includes digital versions of wagering games available in land-based casinos, such as blackjack, roulette and slot machines. For these offerings, the Company functions similarly to land-based casinos, generating revenue through hold, as users play against the house. iGaming revenue is generated from user wagers net of payouts made on users’ winning wagers and incentives awarded to users. DFS, Sportsbook and iGaming, each as described above, create a single performance obligation for the Company to operate contests or games and award prizes or payouts to users based on results. Revenue is recognized at the conclusion of each contest, wager, or wagering game hand. Incentives can be used across online gaming products. Additionally, certain incentives given to customers create material rights and represent separate performance obligations. User incentives in certain cases create liabilities when awarded to players and in those cases are generally recognized as revenue upon redemption. Gaming software The Company contracts with business customers to provide sports and casino betting software solutions. Gaming software revenue is recognized when control of the solutions is transferred to the customer in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for providing control of the sports betting and casino software. The Company’s direct customer contract revenue is generally calculated as a percentage of the wagering revenue generated by the business customer using our software and is recognized in the periods in which those wagering and related activities conclude. In contrast, the Company provides distributors with the right to resell the Company’s software-as-a-service offering to their clients, using their own infrastructure. In reseller arrangements, revenue is generally calculated via a fixed monthly fee and an additional monthly fee which varies based on the number of gaming operators to whom each reseller sub-licenses the Company’s software. Our direct customer arrangements do not provide the customers with the right to take possession of our software, but only the right to purchase access to the Company’s sports and casino wagering software for a defined contractual period. In reseller arrangements, as opposed to direct customer arrangements, the resellers purchase a software license which enables them to install, host, and serve their operators’ base using the Company’s software. As of December 31, 2021, we no longer had agreements with any resellers. Non-fungible token ("NFT") content We launched Draftkings Marketplace (“Marketplace”) during the third quarter of 2021. Marketplace is a digital collectibles (non-fungible token or “NFT”) ecosystem designed for mainstream accessibility that offers curated initial NFT drops (“Primary Sales”). In addition to the Primary Sales, owners of NFTs on Marketplace can list their NFTs for sale to other Marketplace customers (“Secondary Sales”). The revenue we earn is based on a specific percentage of the gross value of each Primary Sale or Secondary Sale. The revenue is recognized for each sale when the NFT transfers to the end user. In addition, the Company signed a strategic agreement (the “Strategic Agreement”) with a privately-held content development company (the “Entity”). Certain officers of the Company are members of the Entity's board of advisors and certain officers and directors of the Company are shareholders of the Entity. In connection with the Strategic Agreement, the Company has exclusive distribution rights for the Entity’s sports-related NFT content. Transaction Price Considerations Variability in the transaction price arises primarily due to market-based pricing, cash discounts, revenue sharing and usage-based fees. DraftKings offers loyalty programs, free plays, deposit bonuses, discounts, rebates and other rewards and incentives to its customers. Revenue for DFS, Sportsbook and iGaming is collected prior to the contest or event and is fixed once the outcome is known. Prizes paid and payouts made to users are recognized when awarded to the player. Contracts with customers may include multiple performance obligations. For such arrangements, the transaction price is allocated to performance obligations on a relative standalone selling price basis. Standalone selling prices are estimated based on observable data of the Company’s sales of such products and services to similar customers and in similar circumstances on a standalone basis. For Online Gaming, which includes DFS, Sportsbook and iGaming, the Company allocates a portion of the transaction price to certain customer incentives that create material future customer rights. In addition, in the event of a multi-stage contest, the Company will allocate transaction price ratably from contest start to the contest’s final stage. Certain costs to obtain or fulfill contracts Under ASC 606, certain costs to obtain or fulfill a contract with a customer must be capitalized, to the extent recoverable from the associated contract margin, and subsequently amor

Under ASC 805, Old DK was deemed the accounting acquirer based on the following predominant factors: its former owners have the largest portion of voting rights in the Company, the Board and Management have more individuals coming from Old DK than either DEAC or SBTech, Old DK was the largest entity by revenue and by assets at the time of the Business Combination, and the headquarters of the Company is Old DK’s headquarters which is located in Boston, Massachusetts. The DK Merger was accounted for as a reverse recapitalization, in accordance with U.S. GAAP. Under this method of accounting, DEAC was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Old DK issuing stock for the net assets of DEAC, accompanied by a recapitalization. The net assets of DEAC are stated at historical cost with no goodwill or other intangible assets recorded. The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization are those of Old DK. Reported shares and earnings per share available to holders of the Company’s common stock, prior to the Business Combination, have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination. Further, Old DK was determined to be the accounting acquirer in the SBTech Acquisition. As such, the SBTech Acquisition was treated as a business combination under ASC 805, and was accounted for using the acquisition method of accounting. DraftKings recorded the fair value of assets acquired and liabilities assumed from SBTech. The business combination agreement contains provisions that indemnifies DraftKings for various losses. Operating results for SBTech are included in the consolidated statements of operations as of December 31, 2020 from the day of the acquisition. The Company acquired 100% of the equity of SBTech pursuant to the Business Combination Agreement by issuing 45.0 million shares, options, and earnout shares of Class A common stock of the Company at a weighted average fair value of $17.53 to the former stockholders and option holders of SBTech. The following summarizes the consideration transferred at Closing for the SBTech Acquisition (in thousands): Cash consideration (1) $ 184,688 Share consideration (2) 789,064 Other cash consideration (3) 3,615 Total SBTech consideration $ 977,367 (1) Includes the cash consideration, adjusted for the Net Debt Amount, the Working Capital Adjustment, and the Aggregate Strike Price Amount, as stipulated by the Business Combination Agreement, resulting in cash consideration of $184.7 million. (2) Includes $776.5 million for the share consideration for SBTech equity of 40.7 million shares and SBTech employees’ vested options of 3.6 million options, and $12.6 million of contingent consideration, which has been paid out, for the 720 thousand earnout shares issued to former stockholders of SBTech as part of the Business Combination, recognized at their Acquisition Date fair value. (3) Includes transaction costs incurred by SBTech shareholders to be borne by DraftKings, costs related to the SBTech restructuring transaction that were paid by DraftKings, and the tail liability insurance for SBTech’s directors and officers, as specified in the Business Combination Agreement. The acquired assets and assumed liabilities of SBTech were recorded at their estimated fair values. The purchase price allocation for the Business Combination was finalized as of December 31, 2020. The following table summarizes the consideration paid for SBTech and the final fair value of the assets acquired and liabilities assumed at the acquisition date on April 23, 2020. Cash and cash equivalents $ 9,639 Trade receivables 17,815 Other current assets 3,674 Property and equipment 10,677 Intangible assets 484,051 Operating lease right-of-use assets 27,696 Other non-current assets 1,017 Total identifiable assets acquired 554,569 Liabilities assumed: Accounts payable and accrued expenses 23,613 Current operating lease liabilities 3,583 Long-term income tax liability 63,575 Non-current operating lease liabilities 24,113 Other long-term liabilities 558 Total liabilities assumed 115,442 Net assets acquired (a) 439,127 Purchase consideration (b) 977,367 Goodwill (b) – (a) $ 538,240 Goodwill represents the excess of the gross considerations transferred over the fair value of the underlying net assets acquired and liabilities assumed. Qualitative factors that contribute to the recognition of goodwill include certain intangible assets that are not recognized as separate identifiable intangible assets apart from goodwill. Intangible assets not recognized apart from goodwill consist primarily of benefits from securing buyer-specific synergies that increase revenue and profits and are not otherwise available to a marketplace participant, as well as acquiring a talented workforce and cost savings opportunities. Goodwill associated with the SBTech Acquisition is assigned as of the acquisition date to the Company’s B2C and B2B segments in the amounts of $348.3 million and $189.9 million respectively, which include the Company’s reporting units that are expected to benefit from the synergies of the combination. Goodwill recognized is not deductible for local tax purposes. Intangible Assets Fair Value Weighted- Developed Technology $ 385,566 8.0 Customer relationships 93,699 5.0 Trademarks and trade names 4,308 3.0 Gaming License 478 2.0 - 3.0 Total $ 484,051 The fair value of the developed technology was determined using the Multi-Period Excess Earnings Method (“MPEEM”), a form of the Income Approach. The MPEEM is a specific application of the Discounted Cash Flow Method. The principle behind the MPEEM is that the value of an intangible asset is equal to the present value of the incremental after-tax cash flows attributable only to the subject intangible asset after deducting contributory asset charges (“CAC”). The principle behind a CAC is that an intangible asset ‘rents’ or ‘leases’ from a hypothetical third party all the assets it requires to produce the cash flows resulting from its development, that each project rents only those assets it needs (including elements of goodwill) and not the ones that it does not need, and that each project pays the owner of the assets a fair return on (and of, when appropriate) the value of the rented assets. The fair value of the customer relationships was determined by using the With and Without Method, a form of the Income Approach. In this method, the present value of the after-tax cash flows of the business assuming that the intangible asset is in place is compared to the present value of the after-tax cash flows of the business assuming the absence of the intangible asset. This method isolates the impact of the intangible asset and provides the basis for an estimation of value. The fair value of the trademark and tradename was determined by using the Relief-from-Royalty Method, a form of the Income Approach. The basic tenet of the Relief-from-Royalty Method is that without ownership of the subject intangible asset, the user of that intangible asset would have to make a stream of payments to the owner of the asset in return for the rights to use that asset. By acquiring the intangible asset, the user avoids these payments. Transaction Costs The Company incurred $30.9 million, for the year ended December 31, 2020, in advisory, legal, accounting and management fees in conjunction with the Business Combination, which are included in general and administrative expenses on the consolidated statement of comprehensive loss. Direct and incremental transaction costs related to the Business Combination and additional equity offerings that would not otherwise have been incurred are treated as a reduction of the cash proceeds and are deducted from the Company’s additional paid-in capital. Accordingly, $63.7 million was incurred related to equity issuance costs for the year ended December 31, 2020. Unaudited Pro-Forma Information The financial information in the table below summarizes the combined results of operations of Old DK and SBTech, on a pro forma basis, as though the companies had been combined as of the beginning of the periods presented. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2019 or of results that may occur in the future. The following pro forma financial information for years ended December 31, 2020 and 2019 combines the historical results for Old DK for the years ended December 31, 2020 and 2019 and the historical results of SBTech, as converted to U.S. GAAP, for the respective periods: Year Ended December 31, 2020 Pro Forma 2019 Pro Forma Revenue $ 643,502 $ 431,834 Net loss $ (1,232,651) $ (219,829) These pro forma results were based on estimates and assumptions, which the Company believes are reasonable. The pro forma results include adjustments primarily related to purchase accounting adjustments. Acquisition costs and other non-recurring charges incurred are included in the earliest period presented. Acquisition of Golden Nugget Online Gaming, Inc. ( “ GNOG ” ) On August 9, 2021, the Company and GNOG entered into a definitive agreement for the Company to acquire GNOG in an all-stock transaction with an implied equity value of approximately $1.56 billion (the “GNOG Transaction”). As part of the GNOG Transaction, the Company will undergo a holding company reorganization whereby a new holding company (“New DraftKings”) will become the going-forward public company for both DraftKings and GNOG. It is expected that New DraftKings will be renamed DraftKings Inc. at the closing of the GNOG Transaction. Under the terms of the agreement and subject to certain exclusions contained therein, GNOG stockholders would receive a fixed ratio of 0.365 shares of New DraftKings’ Class A common stock for each share of GNOG that they hold on the record date. As part of the GNOG Transaction, New DraftKings will also acquire that portion of LHGN Holdco, LLC, the operating subsidiary of GNOG, that is

Current and Long-term Liabilities
Current and Long-term Liabilities	Current and Long-term Liabilities Revolving Line of Credit In October 2016, the Company entered into an amended and restated loan and security agreement with Pacific Western Bank, which was most recently amended in September 2020 (as amended, the “Credit Agreement”). The Credit Agreement provides a revolving line of credit of up to $60.0 million. The Credit Agreement has a maturity date of March 1, 2022. Borrowings under the Credit Agreement bear interest at a variable annual rate equal to the greater of (i) 1.00% above the prime rate then in effect and (ii) 6.50%, and the Credit Agreement requires monthly, interest-only payments. In addition, the Company is required to pay quarterly in arrears a fee equal to 0.25% per annum of the unused portion of the revolving line of credit. As of December 31, 2021 and December 31, 2020, the Credit Agreement provided a revolving line of credit of up to $60.0 million. There was no principal outstanding under the Credit Agreement as of December 31, 2021 and December 31, 2020. Net facility available from the Credit Agreement as of December 31, 2021 and December 31, 2020 totaled $55.8 million, which excludes the letters of credit outlined in Note 16. The Company is also subject to certain affirmative and negative covenants until maturity. In connection with the issuance of the Convertible Notes and the entry into the Capped Call Transactions, the Company obtained a waiver from Pacific Western Bank for any breach of the credit agreement that would have resulted from entering into these financing transactions. The Company also obtained a waiver from Pacific Western Bank for any breach of the credit agreement that would have resulted from exceeding a capital expenditure limitation for 2021 and the amendments to its Annual Report on Form 10-K for the year ended December 31, 2020 and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021 for the previously identified material weakness that has since been remediated as noted in Item 9A. Controls and Procedures. Convertible Notes and Capped Call In March 2021, the Company issued zero-coupon convertible senior notes in an aggregate principal amount of $1,265.0 million, which includes proceeds from the full exercise of the over-allotment option (collectively, the “Convertible Notes”). The Convertible Notes will mature on March 15, 2028, subject to earlier conversion, redemption or repurchase. In connection with the issuance of the Convertible Notes, the Company incurred $17.0 million of lender fees and $1.7 million of debt financing costs which are being amortized through the maturity date. The Convertible Notes represent senior unsecured obligations of the Company. The Convertible Notes are convertible at an initial conversion rate of 10.543 shares of the Company’s Class A common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $94.85 per share of Class A common stock. The conversion rate is subject to adjustment upon the occurrence of certain specified events and includes a make-whole adjustment upon early conversion in connection with a make-whole fundamental change (as defined within the indenture agreement). Prior to September 15, 2027, the Convertible Notes will be convertible only upon satisfaction of certain conditions and during certain periods, and thereafter, at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. The Company will satisfy any conversion election by paying or delivering, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock. During 2021, the conditions allowing holders of the Convertible Notes to convert their Convertible Notes were not met. In connection with the pricing of the Convertible Notes and the exercise of the option to purchase additional notes, the Company entered into a privately negotiated capped call transaction (“Capped Call Transactions”). The Capped Call Transactions have a strike price of $94.85 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Convertible Notes. The Capped Call Transactions have an initial cap price of $135.50 per share, subject to certain adjustments. The Capped Call Transactions are expected generally to reduce potential dilution to the Company's Class A common stock upon any conversion of Convertible Notes. As the transaction qualifies for equity classification, the net cost of $124.0 million incurred in connection with the Capped Call Transactions was recorded as a reduction to additional paid-in capital on the Company's consolidated balance sheet. As of December 31, 2021, the Company's convertible debt balance was $1,248.5 million, net of debt issuance costs of $16.5 million. Although recorded at amortized cost on the Company's consolidated balance sheet, the estimated fair value of the Convertible Notes was $953.8 million as of December 31, 2021 which was calculated using the estimated or actual bids and offers of the Convertible Notes in an over-the-counter market on the last business day of the period. Indirect Taxes Taxation of e-commerce is becoming more prevalent and could negatively affect the Company’s business as it pertains to DFS and its users. The ultimate impact of indirect taxes on the Company’s business is uncertain, as is the period required to resolve this uncertainty. The Company’s estimated contingent liability for indirect taxes represents the Company’s best estimate of tax liability in jurisdictions in which the Company believes taxation is probable. The Company frequently reevaluates its tax positions for appropriateness. Indirect tax statutes and regulations are complex and subject to differences in application and interpretation. Tax authorities may impose indirect taxes on Internet-delivered activities based on statutes and regulations which, in some cases, were established prior to the advent of the Internet and do not apply with certainty to the Company’s business. The Company’s estimated contingent liability for indirect taxes may be materially impacted by future audit results, litigation and settlements, should they occur. The Company’s activities by jurisdiction may vary from period to period, which could result in differences in the applicability of indirect taxes from period to period. As of December 31, 2021, and December 31, 2020, the Company’s estimated contingent liability for indirect taxes was $47.5 million and $45.9 million, respectively. The estimated contingent liability for indirect taxes is recorded within other long-term liabilities on the consolidated balance sheets and general and administrative expenses on the consolidated statements of operations. Warrant Liabilities As part of DEAC’s initial public offering on May 14, 2019, DEAC issued 13.3 million warrants each of which entitles the holder to purchase one share of Class A common stock at an exercise price of $11.50 per share (the “Public Warrants”). Simultaneously with the closing of the IPO, DEAC completed the private sale of 6.3 million warrants to DEAC’s sponsor (the “Private Warrants”). As of December 31, 2021, there were no Public Warrants outstanding. As of December 31, 2021, 1.6 million Private Warrants remained outstanding at a fair value of $26.9 million. Due to fair value changes, the Company recorded a gain on remeasurement of warrant liabilities of $30.1 million and a loss on remeasurement of warrant liabilities of $387.6 million during 2021 and 2020, respectively. During 2021, 0.3 million Private Warrants were exercised, resulting in a reclassification to additional paid-in-capital in the amount of $9.2 million, reflecting the reclassification of the warrant liabilities of $8.5 million and proceeds upon exercise of $0.7 million. During 2020, 17.7 million Private Warrants were exercised, resulting in a reclassification to additional paid-in-capital in the amount of $649.1 million, reflecting the reclassification of the warrant liabilities of $447.1 million and proceeds upon exercise of $202.0 million.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Certain assets and liabilities are carried at fair value under U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The following tables set forth the fair value of the Company’s financial assets and liabilities measured at fair value as of December 31, 2021 and December 31, 2020 based on the three-tier fair value hierarchy: December 31, 2021 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds (1) $ 550,169 $ — $ — $ 550,169 Other non-current assets: Equity securities (2) 27,200 — — 27,200 Put options in Vivid Seats, Inc.

The Company classifies its money market funds as Level 1 because the Company values these assets using quoted market prices. (2) The Company measures its marketable equity securities at fair value. The Company classifies its marketable equity securities as Level 1 because the Company values these assets using quoted market prices. As of December 31, 2021, these marketable equity securities include the Company's investment of 2.5 million shares of Class A Common Stock in Vivid Seats Inc. During the fourth quarter of 2021, the Company also obtained the option to sell its 2.5 million shares of Class A Common Stock in Vivid Seats, Inc., at a price of $9.77 per share to a third party. The change in the fair value of these put options between the acquisition date in the fourth quarter of 2021 and December 31, 2021 was not significant. During 2021, the Company recorded $6.1 million of unrealized gains between the equity securities and the related options. The Company measures its put options in Vivid Seats, Inc. at fair value using a Black-Scholes model and accordingly classifies these put options as Level 3. The following table provides qualitative information regarding the assumptions used to fair value the instrument: December 31, 2021 Class A common stock price $ 10.88 Repurchase price $ 9.77 Term to repurchase date (in years) 0.71 years Volatility 60.0 % Risk-free rate 0.3 % Dividend yield 0.0 %

Equity [Abstract]
Stockholders' Equity (Deficit)	Stockholders’ Equity (Deficit) The consolidated statements of changes in equity reflect the Reverse Recapitalization and SBTech Acquisition as defined in Note 1 as of April 23, 2020. As Old DK was deemed the accounting acquirer in the Reverse Recapitalization with DEAC, all periods prior to the consummation date reflect the balances and activity of Old DK. The consolidated balances as of December 31, 2019 from the audited consolidated financial statements of Old DK as of that date, share activity (convertible redeemable preferred stock and common stock) and per share amounts in these consolidated statements of equity were retroactively adjusted, where applicable, using the recapitalization exchange ratio of 0.353628. All convertible redeemable preferred stock classified as mezzanine was retroactively adjusted, converted into Class A common stock, and reclassified to permanent as a result of the Reverse Recapitalization. Redeemable convertible preferred Series E-1 stock converted into shares of Old DK common stock at a share conversion factor of 1.40 whereas Series F converted into shares of Old DK common stock at a share conversion factor of 1 and both were immediately exchanged for Class A common stock of the Company using the recapitalization exchange ratio of 0.353628 as a result of the Reverse Recapitalization. Immediately prior to the Business Combination, Old DK issued 393.0 million shares of Class B common stock to Jason Robins (the Chief Executive Officer of Old DK and of the Company) which converted into 393.0 million shares of Class B common stock of the Company as a result of the Business Combination and is recorded as stock-based compensation for the year ended December 31, 2020. Such shares carry 10 votes per share and allow Jason Robins to have as of the closing of the Business Combination, approximately 90% of the voting power of the capital stock of DraftKings on a fully-diluted basis. As these shares have no economic rights and are non-participating, they are allocated no earnings or losses when calculating earnings per share pursuant to the two-class method. Upon the consummation of the Business Combination, the mandatory conversion feature was triggered for the Company’s convertible notes then outstanding. As a result, all outstanding principal of $109.2 million and unpaid accrued interest of $3.4 million was collectively converted to equity securities at $10 per share. The noteholders received 11.3 million shares of Class A common stock in New DraftKings as result of the conversion. As part of the Business Combination $542.3 million of Class A common stock and Additional Paid in Capital was recorded, net of transaction costs of $10.6 million, in relation to DEAC shares being recapitalized. The Company then used $188.3 million as cash consideration in its acquisition of SBTech and $7.2 million for the buyout of unaccredited investors. Net cash proceeds to the Company were $484.0 million. In June 2020, we issued 16.0 million new shares of our Class A common stock in a public offering for net proceeds (net of underwriting fees) of $620.8 million. In October 2020, the Company issued 20.8 million shares of its Class A common stock in a public offering for net proceeds (net of underwriting fees) of $1,059.3 million. As of December 31, 2021, the Company had 300.0 million shares authorized of preferred stock, $0.0001 par value, of which none were issued and outstanding as of December 31, 2021 or December 31, 2020.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation In 2012, the Board of Directors adopted the 2012 Stock Option and Restricted Stock Incentive Plan (the “2012 Plan”), which provides for the granting of incentive and nonqualified stock options, shares of restricted stock and other equity interests or awards in the Company. The Company only issued time-based vesting awards under the 2012 Plan. In 2017, the Board approved the 2017 Equity Incentive Plan (the “2017 Plan”). No new awards have been issued under the 2012 Plan following the approval of the 2017 Plan. The 2017 Plan provides for the granting of incentive and nonqualified stock options, shares of restricted stock and other equity interests or awards in the Company. The Company issued time-based and performance-based vesting awards under the 2017 Plan. As of December 31, 2021, the total combined number of shares available for grant under the 2012 Plan and 2017 Plan was 10.4 million. In 2020, the Board approved the 2020 Incentive Award Plan (the “2020 Plan”, together with the 2012 Plan and the 2017 Plan, the “Plans”). The 2020 Plan provides for the granting of incentive and nonqualified stock options, restricted stock units (“RSUs”) and other equity interests or awards in the Company. As of December 31, 2021, the total number of shares available for grant under the 2020 Plan was 44.5 million shares. The Company issued time-based and performance-based vesting awards under the 2020 Plan. As of December 31, 2021, a share reserve established that the aggregate number of shares may not exceed 900.0 million shares under the Plans. The Company has historically issued three types of stock-based compensation: time-based awards, long term incentive plan (“LTIP”) awards and performance-based stock compensation plan (“PSP”) awards. LTIP awards are performance-based equity awards that are used to establish longer-term performance objectives and incentivize management to meet those objectives. PSP awards are short-term performance-based equity awards which establish performance objectives related to one two seven Time-based awards generally vest over a four-year period in annual and/or quarterly installments and expire no later than ten years from the date of grant. Time-based options are valued using the Black-Scholes option-pricing model with the assumptions noted in the table below. The fair value of time-based RSUs is estimated on the grant date using the underlying share price. LTIP awards that were granted as RSUs in 2021 vest based on long-term revenue targets and used the underlying share price on the grant date to estimate their fair value. LTIP awards that were granted as RSUs in 2020 vested based on reaching specific share price targets and used a Monte Carlo Simulation with the assumptions noted in the table below to estimate their fair value. Prior to 2020, LTIP awards were granted as stock options and were valued using the Black-Scholes option-pricing model with the assumptions noted in the table below. PSP awards granted in 2021 and 2020 vest based on meeting both revenue and EBITDA targets. As these awards are performance-based RSUs, the fair value is estimated on the grant date using the underlying share price. Prior to 2020, PSP awards were granted as stock options and were valued using the Black-Scholes option-pricing model with the assumptions noted in the table below. The fair value of each option is estimated on the grant date using the Black-Scholes option-pricing model and the assumptions noted in the table below. The fair value is recognized over the requisite service period of the awards, which is generally the vesting period. For awards with only service-based vesting conditions, the Company recognizes compensation cost using the straight-line method. Expected volatility is based on average volatility for a representative sample of comparable public companies. Stock options are generally granted with an exercise price equal to the fair value of the common stock at the grant date with a 10-year contractual term. The expected term represents the period of time that the options are expected to be outstanding. The expected term is estimated using the average of the vesting term and the original contractual term of the option. The risk-free interest rate is estimated using the rate of return on U.S. treasury notes with a life that approximates the expected life of the option. The fair value of the stock options issued was measured using the following assumptions: Year ended December 31, 2021 2020 2019 Risk free interest rate 1.1 % 0.4 % 2.0 % Expected term (in years) 5.8 6.1 6.0 Expected volatility 43.0 % 42.5 % 41.5 % Expected dividend yield 0.0 % 0.0 % 0.0 % For grants with market-based conditions, the fair value of each award was determined using a Monte Carlo Simulation. No awards with market-based conditions were granted in 2021. The model uses multiple input variables that determined the probability of satisfying the market condition requirements as follows: Year ended Risk free interest rate 1.7 % Expected volatility 38.9 % Expected dividend yield 0.0 % The following table shows stock option activity for the year ended December 31, 2021, 2020, and 2019: Time-based PSP LTIP Total Weighted Weighted Weighted Aggregate Intrinsic Options RSUs Options RSUs Options RSUs Outstanding at December 31, 2019 27,853 — 3,972 — 16,201 — 48,026 $ 2.86 $ — 7.64 $ 203,431 Granted 4,781 3,816 — 907 — 28,354 37,858 4.11 34.63 — — Exercised options / vested RSUs (11,621) (149) (932) — (2,347) (15,554) (30,603) 1.28 21.03 — — Forfeited (494) (119) (17) — — — (630) 5.24 33.72 — — Outstanding at December 31, 2020 20,519 3,548 3,023 907 13,854 12,800 54,651 3.57 47.01 7.05 1,607,562 Granted 1,100 2,466 — 600 — 6,744 10,910 50.60 52.97 — — Exercised options / vested RSUs (6,571) (1,523) (667) — (2,183) — (10,944) 3.33 37.64 — — Forfeited (353) (296) (2) (19) — (201) (871) 4.30 44.20 — — Outstanding at December 31, 2021 14,695 4,195 2,354 1,488 11,671 19,343 53,746 $ 5.46 $ 49.94 6.34 $ 662,108 The following table provides additional information for stock option awards outstanding as of December 31, 2021: Awards Outstanding Weighted Average Remaining Term of Options (Years) Aggregate Intrinsic Value Weighted Average Exercise Price of Options Stock options exercisable 25,276 6.13 $ 605,212 $ 3.86 Stock option expected to vest 3,444 7.87 $ 56,896 $ 17.05 As of December 31, 2021, total unrecognized stock-based compensation expense of $742.0 million related to granted and unvested share-based compensation arrangements is expected to be recognized over a weighted-average period of 1.8 years.

The Company has provided a valuation allowance for the U.S. deferred tax assets as of December 31, 2021. For the year ended December 31, 2021, the U.S. valuation allowance increased by $575.2 million primarily based on the current year operating loss and intangible assets. As of December 31, 2021, the Company had U.S. federal and state tax net operating loss carryforwards of $2,722.0 million and $2,996.0 million, respectively, which may be available to offset future income tax liabilities. Of the federal net operating loss carryforward, $676.2 million expires at various dates beginning in 2032 through 2037 and $2,045.8 million does not expire. Of the state net operating loss carryforward, $2,875.3 million expires at various dates beginning in 2022 through 2041 and $120.7 million does not expire. Utilization of the NOL carryforwards may be subject to limitation under Section 382 of the Internal Revenue Code of 1986 based on ownership changes that have occurred previously or that could occur in the future. These ownership changes may limit the amount of NOL and tax credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. There could be additional ownership changes in the future, which may result in additional limitations on the utilization of the NOL and tax credit carryforwards. The Company has analyzed the impact of these limitations on its attributes and included the impact of these limitations in its U.S. deferred tax assets. As of December 31, 2021, foreign earnings of $9.7 million have been retained by the Company’s foreign subsidiaries for indefinite reinvestment. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company could be subject to withholding taxes payable to the various foreign countries. Determination of the amount of unrecognized deferred income tax liability related to these outside basis differences is not practicable. In addition to filing federal income tax returns, the Company files income tax returns in numerous states and foreign jurisdictions that impose an income tax. The Company is subject to U.S. federal, state and local income tax examinations by tax authorities for the years beginning in 2012. Tax years after 2012 remain open in certain major foreign jurisdictions and are subject to examination by the taxing authorities. The following table presents a reconciliation of the total amounts of unrecognized tax benefits, excluding interest and penalties, included in long-term income tax liabilities on the Company's consolidated balance sheets: Year ended December 31, 2021 2020 2019 Unrecognized tax benefits at the beginning of the year $ 70,341 $ — $ — Additions for tax positions of prior years — 70,341 — Foreign currency adjustments 2,066 — — Unrecognized tax benefits at the end of the year $ 72,407 $ 70,341 $ — If the unrecognized tax benefit balance as of December 31, 2021 were recognized, it would decrease the Company’s effective tax rate. The Company does not anticipate any material changes to its unrecognized tax benefits within the next 12 months. The Company recognizes interest and penalties accrued related to unrecognized tax benefits as income tax expense. During the years ended December 31, 2021, 2020 and 2019 the Company recognized $5.0 million, $1.7 million and $0.0 million in interest and penalties. The Company had $6.7 million, $1.7 million and $0.0 million of interest and penalties accrued at December 31, 2021, 2020 and 2019, respectively.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company operates its business and reports its results through two operating and reportable segments: B2C and B2B, in accordance with ASC Topic 280, Segment Reporting . The B2C segment provides users with DFS, Sportsbook and iGaming products, as well as media and other online consumer product offerings. The B2B segment is involved in the design, development and licensing of sports betting and casino gaming software for its Sportsbook and casino gaming products, which is primarily comprised of SBTech. Operating segments are components of the Company for which separate discrete financial information is available to and evaluated regularly by the chief operating decision maker (“CODM”), who is the Company’s Chief Executive Officer, in making decisions regarding resource allocation and assessing performance. The CODM assesses a combination of metrics such as revenue and Adjusted EBITDA to evaluate the performance of each operating and reportable segment. The accounting policies of our two segments are the same as those described in Note 2, “Summary of Significant Accounting Policies and Practices.” Any intercompany revenues or expenses are eliminated in consolidation. All of the Company’s operating revenues and expenses, other than those excluded from Adjusted EBITDA as detailed below, are allocated to the Company’s reportable segments. We define and calculate Adjusted EBITDA as net loss before the impact of interest income or expense, income tax expense and depreciation and amortization, and further adjusted for the following items: stock-based compensation, transaction-related costs, litigation, settlement and related costs and certain other non-recurring, non-cash and non-core items, as described in the reconciliation below. A measure of segment assets and liabilities has not been currently provided to the Company’s CODM and therefore is not shown below. Summarized financial information for the Company’s segments is shown in the following table: Year ended December 31, 2021 2020 2019 Revenue: B2C $ 1,198,610 $ 538,903 $ 323,410 B2B 97,415 75,629 — Total revenue 1,296,025 614,532 323,410 Adjusted EBITDA: B2C (654,432) (393,461) (98,640) B2B (21,701) 1,542 — Total adjusted EBITDA (676,133) (391,919) (98,640) Adjusted for: Depreciation and amortization 121,138 77,410 13,636 Interest expense (income), net (1,957) 1,070 (1,348) Income tax (benefit) provision 8,269 (622) 58 Stock-based compensation 683,293 325,038 17,613 Transaction-related costs 25,316 36,406 10,472 Litigation, settlement and related costs 10,392 6,839 3,695 Advocacy and other related legal expenses 40,415 — — (Gain) loss on remeasurement of warrant liabilities (30,065) 387,565 — Other non-recurring, special project and non-operating (income) costs (9,739) 6,210 (32) Net Loss attributable to common shareholders $ (1,523,195) $ (1,231,835) $ (142,734) Due to the timing of the Business Combination, the year ended December 31, 2020 reflects B2B/SBTech activity beginning April 24, 2020 and the year ended December 31, 2019 does not reflect B2B/SBTech activity.

Related-Party Transactions	Related-Party Transactions Media Purchase Agreement (“MPA”) In July 2015, Old DK entered into an MPA with a related party for various media placements from 2015 through 2018. The MPA was amended to extend through 2021. The annual commitment for calendar years 2017 through 2021 was $15.0 million per year, plus an additional contingent commitment of $5.0 million per year. The contingent commitment relates to the Company’s allocation of its non-integration advertising with other advertisers. Effective January 2019, the future minimum commitments related to the MPA were reduced to $15.0 million in aggregate through December 31, 2021 ($5.0 million per year) and the contingent commitment was removed. As the Company satisfied the $15.0 million commitment, the MPA has expired. The Company recorded expense of $0.0 million, $25.8 million and $8.4 million related to the MPA for the years ended December 31, 2021, 2020, and 2019, respectively, in sales and marketing expenses in the consolidated statements of operations. Financial Advisor and Private Placement Agent Old DK entered into an engagement letter with a related party (the “Financial Advisor”) in August 2019, as amended in December 2019. Pursuant to the engagement letter, the Financial Advisor acted as the Private Placement Agent to Old DK, and Old DK agreed to pay certain acquisition and financing fees in connection with the Business Combination with SBTech and DEAC. In addition, this Financial advisor was also engaged to assist with the GNOG Transaction. For the years ended December 31, 2021, 2020, and 2019, the Company incurred $2.5 million, $12.3 million, and $0.0 million, respectively, of fees.

Leases, Commitments and Contingencies	Leases, Commitments and Contingencies Leases The Company leases corporate office facilities, data centers, and motor vehicles under operating lease agreements. Some of the Company's leases include one or more options to renew. For a majority of our leases, we do not assume renewals in our determination of the lease term as the renewals are not deemed to be reasonably assured. Our lease agreements generally do not contain any material residual value guarantees or material restrictive covenants. As of December 31, 2021, the Company’s lease agreements typically have terms not exceeding ten years. Payments under the Company’s lease arrangements may be fixed or variable, and variable lease payments primarily represent costs related to common area maintenance and utilities. The components of lease expense are as follows: December 31, 2021 December 31, 2020 Operating lease cost $ 16,551 $ 14,968 Short term lease cost 3,273 2,538 Variable lease cost 4,261 3,652 Sublease income (774) (1,382) Total lease cost $ 23,311 $ 19,776 Other information related to leases are as follows: December 31, 2021 December 31, 2020 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 17,162 $ 11,586 Right-of-use assets obtained in exchange for new operating lease liabilities $ 3,329 $ 42,673 Weighted-average remaining lease term (in years): Operating leases 5.8 Weighted-average discount rate: Operating leases 6.5 % The Company calculated the weighted-average discount rates using incremental borrowing rates, which equal the rates of interest that it would pay to borrow funds on a fully collateralized basis over a similar term.

In Re: Daily Fantasy Sports Litigation (Multi-District Litigation) Between late 2015 and early 2016, certain individuals who allegedly registered and competed in daily sports fantasy contests on our and FanDuel’s websites, and their family members, filed numerous actions (primarily purported class actions) against us, FanDuel, and other related parties in courts across the United States. In February 2016, these actions were consolidated in a multi-district litigation in the U.S. District Court for the District of Massachusetts. The plaintiffs asserted 27 claims arising under both state and federal law against the DFS defendants. The plaintiffs’ claims against us generally fall into four categories: (1) the Company’s online daily fantasy sports contests constitute illegal gambling; (2) the Company promulgated false or misleading advertisements that emphasized the ease of play and likelihood of winning; (3) the Company induced consumers to lose money through a deceptive bonus program; and (4) the Company allowed our employees to participate in competitors’ fantasy sports contests using non-public information, which gave such employees an unfair advantage over other contestants. The plaintiffs seek money damages, equitable relief, and disgorgement of gains against the Company. On October 6, 2021, the court entered judgment and an order approving a settlement and dismissing the claims with prejudice brought by all plaintiffs except the family members plaintiffs and one plaintiff asserting claims against the DFS defendants as a concerned citizen of the State of Florida. This settlement agreement became effective on November 5, 2021; as a result, the only remaining plaintiffs are the family member plaintiffs and the plaintiff who asserted the concerned citizen claims. On January 21, 2022, DraftKings and the family member plaintiffs filed a joint motion for preliminary approval of a proposed settlement; the court heard the motion on January 25, 2022 but has not yet preliminarily approved the proposed settlement. Once the family member settlement agreement becomes effective, the only remaining plaintiff will be the plaintiff who filed the concerned citizen claims. The Company intends to vigorously defend this case. If the plaintiffs obtain a judgment in their favor in this matter, the Company could be subject to substantial damages and it could be restricted from offering DFS contests in certain states. The Company established an accrual for this matter, but it cannot provide any assurance as to the outcome of this lawsuit. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. 1,000 Mass Arbitration Demands Filed by One Law Firm On October 21, 2019, a law firm filed 1000 “mass arbitrations” against the Company with the American Arbitration Association (“AAA”) on behalf of purported DraftKings users that assert claims similar to those in the multi-district litigation described above. After the law firm filed the 1000 “mass arbitrations,” the AAA informed DraftKings in writing that it would close their files on, and decline to administer, the 1000 “mass arbitrations” unless the Company waived two provisions in its terms of use and that the parties would then be free to bring their claims in court. The Company elected not to waive the subject terms of use provisions. On November 6, 2020, the same law firm filed a complaint against DraftKings in Massachusetts Superior Court (Suffolk County), entitled Aaron Abramson, et al. v. DraftKings . In Abramson , the law firm sought, among other things, to compel arbitration against DraftKings on behalf of nine hundred ninety-nine (999) individuals. The Company established an accrual for this matter. On August 7, 2021, DraftKings entered into a settlement agreement which, among other things, resolved the Abramson lawsuit. On or about September 8, 2021, the plaintiffs and DraftKings filed a joint dismissal (without prejudice) of the Abramson lawsuit. Interactive Games LLC On June 14, 2019, Interactive Games LLC filed suit against the Company in the U.S. District Court for the District of Delaware, alleging that our Daily Fantasy Sports product infringes two patents and the Company’s Sportsbook product offering infringes two different patents. DraftKings intends to vigorously defend this case. In the event that a court ultimately determines that the Company is infringing the asserted patents, it may be subject to substantial damages, which may include treble damages and/or an injunction that could require the Company to modify certain features that we currently offer. The Company cannot predict with any degree of certainty the outcome of the suit or determine the extent of any potential liability or damages. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in these matters could expose the Company to substantial damages or penalties that may have a material adverse impact on the Company’s operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. Winview Inc. On July 7, 2021, Winview Inc., a Delaware Corporation filed suit against the Company in the U.S. District Court for the District of New Jersey, which was subsequently amended on July 28, 2021, alleging that our Sportsbook product infringes two patents, our Daily Fantasy Sports product infringes one patent, and that our Sportsbook product and Daily Fantasy Sports product infringes another patent. On November 15, 2021, Winview filed a second amended complaint (the “SAC”), adding as defendants DraftKings Inc., a Delaware Corporation, and Crown Gaming Inc., a Delaware Corporation. The SAC largely repeats the allegations of the first amended complaint. DraftKings intends to vigorously defend this case. In the event that a court ultimately determines that the Company is infringing the asserted patents, it may be subject to substantial damages, which may include treble damages and/or an injunction that could require the Company to modify certain features that we currently offer. The Company cannot predict with any degree of certainty the outcome of the suit or determine the extent of any potential liability or damages. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in these matters could expose the Company to substantial damages or penalties that may have a material adverse impact on the Company’s operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. Securities Matters On July 2, 2021, the first of two substantially similar federal securities law putative class actions was filed in the U.S. District Court for the Southern District of New York against the Company and certain of its officers. The actions allege violations of Sections 10(b) and 20(a) of the Exchange Act on a behalf of a putative class of persons who purchased or otherwise acquired DraftKings stock between December 23, 2019 and June 15, 2021. The allegations relate to, among other things, allegedly false and misleading statements and/or failures to disclose information about the Company’s business and prospects, based primarily upon the allegations concerning SBTech that were contained in a report published about the Company on June 15, 2021 by Hindenburg Research (the “Hindenburg Report”). The Company intends to vigorously defend against these claims. On November 12, 2021, the Court consolidated the two actions under the caption In re DraftKings Securities Litigation and appointed a lead plaintiff. The lead plaintiff filed a consolidated amended complaint on January 11, 2022. On July 9, 2021, the Company received a subpoena from the SEC seeking documents concerning certain of the allegations raised in the Hindenburg Report. The Company intends to comply with the related requests and is cooperating with the SEC’s ongoing inquiry. The Company cannot predict with any degree of certainty the outcome of these matters or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in these matters could expose the Company to substantial damages or penalties that may have a material adverse impact on the Company’s operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. Shareholder Derivative Litigation On October 21, 2021, the first of four substantially similar putative shareholder derivative actions was filed in Nevada by alleged shareholders of the Company. The actions purport to assert claims on behalf of the Company against certain current and former officers and/or members of the Board of Directors of the Company and DEAC. Two actions were filed in the U.S. District Court for the District of Nevada, and two actions were filed in Nevada state District Court in Clark County. The actions purport to assert claims on behalf of the Company for, among other things, breach of fiduciary duty and corporate waste based primarily upon the allegations concerning SBTech that were contained in the Hindenburg Report. The two federal court actions also contend that certain individuals are liable to the Company for any adverse judgment in the federal securities class actions described above under Sections 10(b) and 21D of the Exchange Act. The complaint seeks unspecified compensatory damages, changes to corporate governance and internal procedures, equitable and injunctive relief, restitution, costs and attorney's fees. The Company cannot predict with any degree of certainty the outcome of these matters or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss. Because these actions allege claims on behalf of the Company and purport to seek a judgment in favor of the Company, the Company does not believe, based on currently available information, that the outcome of these proceedings will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. AG 18, LLC d/b/a/ Arrow Gaming On August 19, 2021, AG 18, LLC d/b/a/ Arrow Gaming (“Arrow Gaming”) filed a complaint against DraftKings in the United States District Court for the District of New Jersey alleging that DraftKings’ DFS and Casino products infringe four patents. On October 12, 2021, Arrow Gaming filed an amended complaint to add one additional patent. On December 20, 2021, Arrow Gaming filed a second amended complaint adding new allegations with respect to alleged willful infringement. The Company cannot predict with any degree of certainty the outcome of the suit or determine the extent of any potential liability or damages. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in these matters could expose the Company to substantial damages or penalties that may have a material adverse impact on the Company’s operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. Beteiro, LLC On November 22, 2021, Beteiro, LLC filed a complaint against the Company in the United States District Court for the District of New Jersey alleging that the Company’s Sportsbook and Casino products infringe four patents. The Company cannot predict with any degree of certainty the outcome of the suit or determine the extent of any potential liability or damages. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in these matters could expose the Company to substantial damages or penalties that may have a material adverse impact on the Company’s operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. Diogenes Ltd. & Colossus(IOM) Ltd. On December 1, 2021, Diogenes Ltd. & Colossus (IOM) Ltd. (“Colossus”), filed a complaint against the Company in the United States District Court for the District of Delaware alleging that the Company’s Sportsbook products infringe seven patents. Colossus amended its complaint on February 7, 2022, to, among other things, add one additional patent. The Company cannot predict with any degree of certainty the outcome of the suit or determine the extent of any potential liability or damages. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in these matters could expose the Company to substantial damages or penalties that may have a material adverse impact on the Company’s operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on DraftKings’ financial condition, although the outcome could be material to DraftKings’ operating results for any particular period, depending, in part, upon the operating results for such period. Internal Revenue Service The Company is currently under Internal Revenue Service audit for prior tax years, with the primary unresolved issues relating to excise taxation of fantasy sports contests and informational reporting and withholding. The final resolution of that audit, and other audits or litigation, may differ from the amounts recorded in these consolidated financial statements and may materially affect the Company’s consolidated financial statements in the period or periods in which that determination is made. Letters of Credit In connection with the Credit Agreement with Pacific Western Bank, the Company has entered into several letters of credit totaling $4.2 million as of December 31, 2021 and December 31, 2020 for the Company’s leases of office space.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies and Practices (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts and operations of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions are eliminated upon consolidation. Certain amounts, which are not material, in the prior years’ consolidated financial statements have been reclassified to conform to the current year presentation. Pursuant to the Business Combination, the merger between a subsidiary of DEAC and Old DK was accounted for as a reverse recapitalization in accordance with U.S. GAAP (the “Reverse Recapitalization”). Under this method of accounting, DEAC was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Old DK issuing stock for the net assets of DEAC, accompanied by a recapitalization. The net assets of DEAC are stated at historical cost, with no goodwill or other intangible assets recorded. The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization are those of Old DK. The shares and corresponding capital amounts and earnings per share available for common stockholders, prior to the Business Combination, have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination. Further, Old DK was determined to be the accounting acquirer in the SBTech Acquisition, as such, the acquisition is considered a business combination under Accounting Standards Codification (“ASC”), Topic 805, Business Combinations , (“ASC 805”) and was accounted for using the acquisition method of accounting. DraftKings recorded the fair value of assets acquired and liabilities assumed from SBTech. The presented financial information for the year ended December 31, 2020 includes the financial information and activities for SBTech for the period from April 24, 2020 to (and including) December 31, 2020. Prior to the second quarter of 2021, the Company (a) included changes in “cash reserved for users” as a component within the change in operating assets and liabilities on its condensed consolidated statement of cash flows as the Company historically viewed the change in cash reserved for users as offsetting the change in player liabilities and (b) presented “cash reserved for users” separate from cash and cash equivalents on the condensed consolidated balance sheet. Beginning with the second quarter of 2021, to reflect the Company's total cash position (“cash and cash equivalents” and “cash reserved for users”) and to conform to Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows (Topic 230) — Restricted Cash , the Company revised its presentation to exclude changes in “cash reserved for users” from the “change in operating assets and liabilities” and instead present the total balance as a component of cash and cash equivalents and restricted cash on its condensed consolidated statement of cash flows.
Comprehensive Loss	Comprehensive Loss Comprehensive loss consists of foreign currency translation adjustments related to the effect of foreign exchange on the value of our assets and liabilities denominated in Euros. The translation gain or loss is included in the consolidated statements of comprehensive loss.
Foreign Currency	Foreign Currency Our reporting currency is the U.S. dollar while the functional currency of the Company’s significant non-U.S. subsidiaries is the Euro. The financial statements of the Company’s significant non-U.S. subsidiaries are translated into United States dollars in accordance with ASC 830, Foreign Currency Matters , using period-end rates of exchange for assets and liabilities, and average rates of exchange for the period for revenues, costs and expenses and historical rates for equity. During 2021, 2020 and 2019, foreign currency transactions did not significantly impact net income.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions reflected in the financial statements relate to and include, but are not limited to, the valuation and expensing of equity awards, accounting for contingencies and uncertainties, purchase price allocations, including fair value estimates of intangible assets, the estimated useful lives of fixed assets and intangible assets, internally developed software costs and accrued expenses.
Going Concern	Going Concern Based on anticipated spend and cash received from the Business Combination, exercise of certain warrants, the June 2020 and October 2020 follow-on equity offerings, the issuance of convertible notes in March 2021 and the timing of expenditure assumptions, the Company currently expects that its cash will be sufficient to fund its operating expenses and capital expenditure requirements for at least 12 months after February 18, 2022. The Company has experienced operating losses and negative operating cash flows for the years ended December 31, 2021, 2020 and 2019. While certain geographies may experience improved cash flow, the Company expects to continue to incur annual operating losses and annual negative operating cash flow for the foreseeable future.
Concentrations Risks and Uncertainties	Concentration Risks and Uncertainties Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of operating cash and cash equivalents and cash reserved for users. The Company maintains separate accounts for cash and cash reserved for users primarily across four financial institutions. Some amounts exceed federally insured limits with the majority of cash held in one financial institution. Management believes all financial institutions holding its cash are of high credit quality and does not believe the Company is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. The Company relies on a limited number of vendors to support operations. In particular, a single vendor is currently the primary provider of web services that allows the Company to host its sports betting, iGaming and daily fantasy sports offerings. Any interruption in the services provided by this supplier could have a material adverse effect on its business, financial condition and results of operations. The Company's growth prospects and market potential will depend on its ability to obtain and maintain licenses to operate in a number of jurisdictions and if the Company fails to obtain and maintain such licenses its business, financial condition, results of operations and prospects could be impaired.
Business Combinations	Business Combinations The Company accounts for business combinations under the acquisition method of accounting, in accordance with ASC 805, which requires assets acquired and liabilities assumed to be recognized at their fair values as of the acquisition date. Any fair value of purchase consideration in excess of the fair value of the assets acquired less liabilities assumed is recorded as goodwill. The fair values of the assets acquired and liabilities assumed are determined based upon the valuation of the acquired business and involve management making significant estimates and assumptions.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents consist of highly liquid, unrestricted savings, money market funds, checking and other bank accounts.
Cash Reserved for Users	Cash Reserved for Users The Company maintains separate bank accounts to segregate users’ funds from operational funds. In certain regulated jurisdictions, user funds are held by DK Player Reserve, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company, which was organized for the purpose of protecting users’ funds in the event of creditor claims.
Receivables Reserved for Users	Receivables Reserved for Users Receivables for user deposits not yet received are stated at the amount the Company expects to collect from a payment processor, which includes an allowance for credit losses if appropriate. These receivables arise, primarily, due to process timing between when a user deposits and when the Company receives that deposit from the payment processor. Receivables also arise due to the securitization policies of certain payment processors. The allowance for credit losses is determined based on the Company’s assessment of the probability of the non-payment of the receivable. This provision is netted against the receivable balance with the loss being recognized within general and administrative expenses in the consolidated statements of operations. The provision at December 31, 2021 and December 31, 2020 did not have a material impact on the Company’s consolidated financial statements.
Accounts Receivables	Accounts Receivables Accounts receivables are recorded at amortized cost, less any allowance for credit losses. The allowance for credit losses is determined based on the Company’s assessment of the probability of non-payment of the receivable. This provision is netted against the receivable balance with the loss being recognized within general and administrative expenses in the consolidated statements of operations. The provision at December 31, 2021 and December 31, 2020 did not have a material impact on the Company’s consolidated financial statements.
Property and Equipment, net	Property and Equipment, Net Property and equipment are carried at cost, net of accumulated depreciation. Depreciation is computed utilizing the straight-line method over the estimated useful life of the asset. Leasehold improvements depreciation is computed over the shorter of the lease term or estimated useful life of the asset. Additions and improvements are capitalized, while repairs and maintenance are expensed as incurred. Useful lives of each asset class are generally as follows: Computer equipment and software 3 years Furniture and fixtures 7 years Leasehold improvements Lesser of the lease terms or the estimated useful lives of the improvements, generally 1–10 years
Intangible Assets, Net	Intangible Assets, Net The Company’s intangible assets consist of developed technology, customer relationships, internally-developed software, gaming licenses, trademarks and tradenames and digital assets. The related amortization expense is classified as cost of revenue in the consolidated statements of operations. Estimates and assumptions that we must make in estimating the fair value of future acquired technology, user lists and other identifiable intangible assets include future cash flows that we expect to generate from the acquired assets. Developed Technology Developed technology primarily relates to the design and development of sports betting and casino gaming software for online and retail sportsbook and casino gaming products acquired from SBTech and other acquisitions and recorded at fair value at the date of acquisition. Customer Relationships Customer (or “user”) relationships are finite-lived intangible assets which are amortized over their estimated economic lives. Customer relationships are generally recognized as the result of business combinations. Internally Developed Software Software that is developed for internal use is accounted for pursuant to ASC 350-40, Intangibles, Goodwill and Other—Internal-Use Software . Qualifying costs incurred to develop internal-use software are capitalized when (i) the preliminary project stage is completed, (ii) management has authorized further funding for the completion of the project and (iii) it is probable that the project will be completed and perform as intended. These capitalized costs include compensation for employees who develop internal-use software and external costs related to development of internal use software. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Internally developed software is amortized using the straight-line method over an estimated useful life. All other expenditures, including those incurred in order to maintain an intangible asset’s current level of performance, are expensed as incurred. Gaming Licenses The Company incurs fees in connection with applying for and maintaining good standing in jurisdictions via business licenses. Fees incurred in connection with the application and subsequent renewals are capitalized and amortized using the straight-line method over an estimated useful life. In certain arrangements, the Company enters into agreements to operate on a business partner’s license in exchange for upfront fees. These fees are capitalized and amortized over the shorter of their expected benefit under the partnership agreement or estimated useful life. Trademarks and Tradenames The Company incurs fees in connection with applying for and maintaining trademarks and tradenames as well as trademarks and tradenames resulting from acquisitions. Fees incurred in connection with the application and subsequent renewals are capitalized and amortized using the straight-line method over an estimated useful life. Digital Assets The Company has purchased certain digital assets, including crypto currencies, with cash that is not required to currently support its operations. The Company accounts for digital assets in accordance with ASC 350, Intangibles—Goodwill and Other (Topic 350). Accordingly, if the fair market value at any point during the reporting period is lower than the carrying value an impairment loss equal to the difference will be recognized in the consolidated statement of operations. If the fair market value at any point during the reporting period is higher than the carrying value the basis of the digital assets will not be adjusted to account for this increase. Gains on digital assets, if any, will be recognized upon sale or disposal of the assets.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets, except for goodwill, consist of property and equipment and finite-lived acquired intangible assets, such as internal-use software, developed software, gaming licenses, trademarks, tradenames and customer relationships. Long-lived assets, except for goodwill, are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the asset may not be fully recoverable. Impairment expense is recognized to the extent an asset’s expected undiscounted future cash flows are less than the asset’s carrying amount. The Company determined that long-lived assets were not significantly impaired 2021, 2020 or 2019.
Goodwill	Goodwill The Company’s business is classified into three reporting units: B2C, Media and B2B. In testing goodwill for impairment, the Company has the option to begin with a qualitative assessment, commonly referred to as “Step 0,” to determine whether it is more likely than not that the fair value of a reporting unit containing goodwill is less than its carrying value. This qualitative assessment may include, but is not limited to, reviewing factors such as macroeconomic conditions, industry and market considerations, cost factors, entity-specific financial performance and other events, such as changes in the Company’s management, strategy and primary user base. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative goodwill impairment analysis by comparing the carrying amount to the fair value of the reporting unit. If the carrying amount exceeds the fair value, goodwill will be written down to the fair value and recorded as impairment expense in the consolidated statements of operations. The Company performs its impairment testing annually and when circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company performed its annual impairment assessment of goodwill as of October 1, 2021 and concluded that goodwill was not impaired.
Equity Method Investment	Equity Method Investment The Company has a 49.9% membership interest in DKFS, LLC, also known as DRIVE by DraftKings as of December 31, 2021. In addition, the Company has committed to invest up to $17.5 million into DBDK Venture Fund I, LP, a Delaware limited partnership and a subsidiary of DKFS LLC. As of December 31, 2021, the Company had invested a total of $3.5 million of the total commitment, which represents ownership of approximately 28.6% in the fund. The Company uses the equity method to account for investments in which the Company has the ability to exercise significant influence over the operating and financial policies of the investee, but does not exercise control and is not the primary beneficiary. The Company’s judgment regarding its level of influence over the equity method investee includes considering key factors, such as ownership interest, representation on the board of directors, and participation in policy-making decisions. The Company’s carrying value in the equity method investee is reflected in the caption “Equity method investment” on the consolidated balance sheets. Changes in value of DKFS, LLC and DBDK Venture Fund I, LP are recorded in “(Gain) Loss from equity method investment” on the consolidated statements of operations. Under the equity method, the Company’s investment is initially measured at cost and subsequently increased or decreased to recognize the Company’s share of income and losses of the investee, capital contributions and distributions and impairment losses. The Company performs a qualitative assessment annually and recognizes an impairment if there are sufficient indicators that the fair value of the investment is less than carrying value.
Leases	Leases The Company leases certain office spaces, equipment and vehicles and recognizes lease expense on a straight-line basis over the initial term of the lease unless external economic factors exist such that renewals are reasonably certain. In those instances, the renewal period would be included in the lease term to determine the period in which to recognize the lease expense. Leases for periods through December 31, 2019 were reported under ASC 840, Leases (Topic 840) (“ASC 840”), including the disclosure requirements. The Company recognizes rent expense on operating leases on a straight-line basis over the non-cancellable lease term. Operating leases with landlord-funded leasehold improvements are considered tenant allowances and are amortized as a reduction of rent expense over the non-cancellable lease term. Deferred rent liability, which is calculated as the difference between contractual lease payments and the rent expense, is recorded in accounts payable and accrued expenses and other long-term liabilities in the consolidated balance sheets. The Company adopted Accounting Standards Update (“ASU”) 2016-2, Leases (Topic 842) (“ASU 2016-2”), using the alternative transition method provided in ASU 2018-11, Leases (Topic 842) (“ASU 2018-11”): Targeted Improvements as of January 1, 2020 at December 31, 2020. Using the alternative transition method, the Company applied the transition requirements at the effective date of ASU 2016-2. The Company elected the package of practical expedients permitted under the transition guidance within the new lease standard. In addition, the Company has elected to apply the practical expedient to combine lease and related non-lease components, for all classes of underlying assets, and account for the combined contract as a lease component, as well as the election was made to apply the short-term lease recognition exemption.
Warrant Liabilities	Warrant Liabilities As part of DEAC’s initial public offering on May 14, 2019, DEAC issued 13.3 million warrants where each whole warrant entitles the holder to purchase one share of Class A common stock at an exercise price of $11.50 per share (the “Public Warrants”). Simultaneously with the closing of the IPO, DEAC completed the private sale of 6.3 million warrants to DEAC’s sponsor at a purchase price of $1.50 per warrant (the “Private Warrants”). Each Private Warrant allows the sponsor to purchase one share of Class A common stock at $11.50 per share. The Private Warrants and the shares of common stock issuable upon the exercise of the Private Warrants are not transferable, assignable or salable until after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Warrants are exercisable for cash or on a cashless basis, at the holder’s option, and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrant. The Company classified the Warrants pursuant to ASC 815 as derivative liabilities with subsequent changes in their respective fair values recognized in the consolidated statement of operations at each reporting date.
Liabilities to Users	Liabilities to Users The Company records liabilities for user account balances. User account balances consist of user deposits, most promotional awards and user winnings less user withdrawals, tax withholdings and user losses. Cash reserved for users and receivables reserved for users equal or exceed the Company’s liabilities to users at all times.
Loss Contingencies	Loss Contingencies The Company’s loss contingencies, which are included within other long-term liabilities in the consolidated balance sheets, are uncertain by nature and their estimation requires significant management judgment as to the probability of loss and estimation of the amount of such loss. These contingencies include, but may not be limited to, indirect taxes, regulatory investigations and proceedings and management’s evaluation of complex laws and regulations, and the extent to which they may apply to our business and industry. The Company regularly reviews its contingencies to determine whether the likelihood of loss is probable and to assess whether a reasonable estimate of the loss can be made. Determination of whether a loss estimate can be made is a complex undertaking that considers the judgement of management, third-party research, the prospect of negotiation and interpretations
Revenue Recognition	Revenue Recognition Effective January 1, 2019, the Company adopted ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), using the modified retrospective method for all contracts not completed as of the date of adoption. ASC 606 requires companies to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the standard requires more detailed disclosures to enable readers of the financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The cumulative effect of the adoption was immaterial to the consolidated financial statements. See Note 10 – Revenue Recognition for further details. The Company determines revenue recognition through the following steps: • Identify the contract, or contracts, with the customer; • Identify the performance obligations in the contract; • Determine the transaction price; • Allocate the transaction price to performance obligations in the contract; and • Recognize revenue when, or as, the Company satisfies performance obligations by transferring the promised good or services. The Company is currently engaged in the business of digital sports entertainment and gaming and provides its users with online gaming opportunities. The Company also provides online sportsbook and casino operators with technical infrastructure as well as related services with respect to its direct customers and distributors. The following is a description of the Company’s revenue streams: Online Gaming DFS is a peer-to-peer product in which users compete against one another for prizes. Users pay an entry fee to join a DFS contest and compete for prizes, which are distributed to the highest performing competitors in each contest as defined by each contest’s prize table. DFS revenue is generated from contest entry fees from users, net of prizes and customer incentives awarded to users. Sportsbook or sports betting involves a user wagering money on an outcome or series of outcomes occurring. When a user’s wager wins, the Company pays the user a pre-determined amount known as fixed odds. Sportsbook revenue is generated by setting odds such that there is a built-in theoretical margin in each sports wagering opportunity offered to users. Sportsbook revenue is generated from users’ wagers net of payouts made on users’ winning wagers and incentives awarded to users. iGaming, or online casino, typically includes digital versions of wagering games available in land-based casinos, such as blackjack, roulette and slot machines. For these offerings, the Company functions similarly to land-based casinos, generating revenue through hold, as users play against the house. iGaming revenue is generated from user wagers net of payouts made on users’ winning wagers and incentives awarded to users. DFS, Sportsbook and iGaming, each as described above, create a single performance obligation for the Company to operate contests or games and award prizes or payouts to users based on results. Revenue is recognized at the conclusion of each contest, wager, or wagering game hand. Incentives can be used across online gaming products. Additionally, certain incentives given to customers create material rights and represent separate performance obligations. User incentives in certain cases create liabilities when awarded to players and in those cases are generally recognized as revenue upon redemption. Gaming software The Company contracts with business customers to provide sports and casino betting software solutions. Gaming software revenue is recognized when control of the solutions is transferred to the customer in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for providing control of the sports betting and casino software. The Company’s direct customer contract revenue is generally calculated as a percentage of the wagering revenue generated by the business customer using our software and is recognized in the periods in which those wagering and related activities conclude. In contrast, the Company provides distributors with the right to resell the Company’s software-as-a-service offering to their clients, using their own infrastructure. In reseller arrangements, revenue is generally calculated via a fixed monthly fee and an additional monthly fee which varies based on the number of gaming operators to whom each reseller sub-licenses the Company’s software. Our direct customer arrangements do not provide the customers with the right to take possession of our software, but only the right to purchase access to the Company’s sports and casino wagering software for a defined contractual period. In reseller arrangements, as opposed to direct customer arrangements, the resellers purchase a software license which enables them to install, host, and serve their operators’ base using the Company’s software. As of December 31, 2021, we no longer had agreements with any resellers. Non-fungible token ("NFT") content We launched Draftkings Marketplace (“Marketplace”) during the third quarter of 2021. Marketplace is a digital collectibles (non-fungible token or “NFT”) ecosystem designed for mainstream accessibility that offers curated initial NFT drops (“Primary Sales”). In addition to the Primary Sales, owners of NFTs on Marketplace can list their NFTs for sale to other Marketplace customers (“Secondary Sales”). The revenue we earn is based on a specific percentage of the gross value of each Primary Sale or Secondary Sale. The revenue is recognized for each sale when the NFT transfers to the end user. In addition, the Company signed a strategic agreement (the “Strategic Agreement”) with a privately-held content development company (the “Entity”). Certain officers of the Company are members of the Entity's board of advisors and certain officers and directors of the Company are shareholders of the Entity. In connection with the Strategic Agreement, the Company has exclusive distribution rights for the Entity’s sports-related NFT content. Transaction Price Considerations Variability in the transaction price arises primarily due to market-based pricing, cash discounts, revenue sharing and usage-based fees. DraftKings offers loyalty programs, free plays, deposit bonuses, discounts, rebates and other rewards and incentives to its customers. Revenue for DFS, Sportsbook and iGaming is collected prior to the contest or event and is fixed once the outcome is known. Prizes paid and payouts made to users are recognized when awarded to the player. Contracts with customers may include multiple performance obligations. For such arrangements, the transaction price is allocated to performance obligations on a relative standalone selling price basis. Standalone selling prices are estimated based on observable data of the Company’s sales of such products and services to similar customers and in similar circumstances on a standalone basis. For Online Gaming, which includes DFS, Sportsbook and iGaming, the Company allocates a portion of the transaction price to certain customer incentives that create material future customer rights. In addition, in the event of a multi-stage contest, the Company will allocate transaction price ratably from contest start to the contest’s final stage. Certain costs to obtain or fulfill contracts Under ASC 606, certain costs to obtain or fulfill a contract with a customer must be capitalized, to the extent recoverable from the associated contract margin, and subsequently amortized as the products or services are delivered to the customer. These costs are capitalized as contract acquisition costs and are amortized over the period of benefit to the customer. For the Company, the period of benefit is typically less than or equal to 1 year. As such, the Company applied the practical expedient and contract acquisition costs are expensed immediately. Customer contract costs which do not qualify for capitalization as contract fulfillment costs are expensed as incurred. Contract balances Contract assets and liabilities represent the differences in the timing of revenue recognition from the receipt of cash from the Company’s customers and billings to those customers. Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing. Deferred revenue relates to payments received in advance of the satisfaction of performance under the contract. The Company maintains various programs to incentivize user behaviors, which allows users to earn awards. Incentive awards generally represent a material right to the user, and awards may be redeemed for future services. Incentive awards earned by users, but not yet redeemed, are generally recognized as a reduction to revenue and included within liabilities to users on the consolidated balance sheets. When a user redeems most types of awards, the Company recognizes revenue on the consolidated statements of operations. Certain player awards are not subject to expiration or have not been expired historically, on such awards the Company recognizes breakage (for amounts not expected to be redeemed) to the extent there is no requirement for remitting such balances to regulatory agencies.
Cost of Revenue	Cost of Revenue Cost of revenue consists primarily of variable costs. These include mainly (i) payment processing fees and chargebacks, (ii) product taxes, (iii) platform costs directly associated with revenue-generating activities, including those costs that were originally capitalized for internally developed software, (iv) revenue share / market access arrangements, and (v) feed / provider services. The Company incurs payment processing fees on user deposits, withdrawals and deposit reversals from payment processors (“chargebacks”). Chargebacks have not been material to date. Cost of revenue also includes expenses related to the distribution of our services, amortization of intangible assets and compensation of revenue associated personnel.
Sales and Marketing	Sales and Marketing Sales and marketing expenses consist primarily of expenses associated with advertising, conferences, costs related to free to play contests, rent and facilities maintenance, and the compensation of sales and marketing personnel, including stock-based compensation expenses. Advertising costs are expensed as incurred and are included in sales and marketing expense in the consolidated statements of operations. Advertising costs include those costs associated with communicating with potential customers and generally use some form of media, such as internet, radio, print, television, or billboards. Advertising costs also include costs associated with strategic league and team partnerships. During the years ended December 31, 2021, 2020 and 2019, advertising costs in accordance with U.S. GAAP were $831.1 million, $430.4 million and $152.2 million, respectively.
Product and Technology	Product and Technology Product and technology expenses consist primarily of research and development costs that are not capitalized and other costs not associated directly with revenue generating activities. Research and development costs primarily represent employee expenses (including stock-based compensation) for engineering product, design, analytical research and project management incurred for non-revenue generating activities. Other costs include related overhead for rent, facilities maintenance, third party software licenses and consulting services.
General and Administrative	General and Administrative General and administrative expenses consist of costs not related to sales and marketing, product and technology or revenue. General and administrative costs include professional services (including legal, regulatory, audit, accounting, lobbying and services related to acquisitions), rent and facilities maintenance, contingencies, insurance, allowance for credit losses, depreciation of leasehold improvements and furniture and fixtures and costs related to the compensation of executive and non-executive personnel, including stock-based compensation.
Benefit Plans	Benefit Plans The Company maintains a defined contribution plan, which covers a majority of employees. The plan allows for employee salary deferrals, which are matched at our discretion. The Company contributions to these plans were $6.7 million in 2021. These costs were not significant to the Company's consolidated financial statements in 2020 or 2019.
Stock-based Compensation	Stock-based Compensation The Company measures compensation expense for stock options and other stock awards in accordance with ASC 718, Compensation—Stock Compensation . Stock-based compensation is measured at fair value on grant date and recognized as compensation expense over the requisite service period. Generally, the Company issues stock options and other stock awards to employees with service-based and/or performance-based vesting conditions. For awards with only service-based vesting conditions, the Company records compensation cost for these awards using the straight-line method less an assumed forfeiture rate. For awards with performance-based vesting conditions, the Company recognizes compensation cost on a tranche-by-tranche basis (the accelerated attribution method) less an assumed forfeiture rate. Under the provisions of ASC 505-50, Equity-Based Payments to Non-Employees , the Company measures stock-based awards granted to non-employees at the earlier of: (i) the performance commitment date, or (ii) the date the services required under the arrangement have been completed. Compensation expense is recognized over the period during which services are
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between U.S. GAAP treatment and tax treatment of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by considering taxable income in carryback years, existing taxable temporary differences, prudent and feasible tax planning strategies and estimated future taxable profits. The Company accounts for uncertainty in income taxes recognized in the consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate, as well as the related net interest and penalties.
Earnings (loss) per share	Earnings (loss) per share Basic earnings (loss) per share is calculated using the two-class method. Under the two-class method, basic earnings (loss) is computed by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period excluding the effects of any potentially dilutive securities. The weighted-average number of common shares outstanding during the period includes Class A common stock but is exclusive of Class B common stock as these shares have no economic or participating rights. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if potential common shares had been issued if such additional common shares were dilutive. Since the Company had net losses for all the periods presented, basic and diluted earnings (loss) per share are the same, and additional potential common shares have been excluded, as their effect would be anti-dilutive.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company elected to early adopt the new standard as of January 1, 2021 using the modified retrospective approach. In the first quarter of 2021, the Company issued convertible senior notes, whereby the entire proceeds from issuance were recognized as a liability, net of any lender fees and debt financing costs, on our condensed consolidated balance sheet. Please refer to Note 7 included herein for additional information. In December 2019, the FASB issued ASU 2019-12, Income Taxes—Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this standard as of January 1, 2021. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures. Recently Issued Accounting Pronouncements Not Yet Adopted In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities in accordance with Accounting Standards Codification Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. While the Company is continuing to assess the timing of adoption and the potential impacts of ASU 2021-08, it does not expect ASU 2021-08 to have a material effect, if any, on its consolidated financial statements.

The Company classifies its money market funds as Level 1 because the Company values these assets using quoted market prices. (2) The Company measures its marketable equity securities at fair value. The Company classifies its marketable equity securities as Level 1 because the Company values these assets using quoted market prices. As of December 31, 2021, these marketable equity securities include the Company's investment of 2.5 million shares of Class A Common Stock in Vivid Seats Inc. During the fourth quarter of 2021, the Company also obtained the option to sell its 2.5 million shares of Class A Common Stock in Vivid Seats, Inc., at a price of $9.77 per share to a third party. The change in the fair value of these put options between the acquisition date in the fourth quarter of 2021 and December 31, 2021 was not significant. During 2021, the Company recorded $6.1 million of unrealized gains between the equity securities and the related options. The Company measures its put options in Vivid Seats, Inc. at fair value using a Black-Scholes model and accordingly classifies these put options as Level 3.
