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 September 30, 2021, the U.S. jurisdictions with statutes legalizing online sports betting are Arizona, Colorado, Connecticut, Florida, Illinois, Indiana, Iowa, Louisiana, Maryland, Michigan, Nevada, New Hampshire, New Jersey, New York, Oregon, Pennsylvania, Puerto Rico, Rhode Island, Tennessee, Virginia, Washington, D.C, West Virginia and Wyoming. The jurisdictions with statutes legalizing sports betting at certain land-based retail locations are Arizona, Arkansas, Colorado, Connecticut, Delaware, Florida, Illinois, Indiana, Iowa, Louisiana, Maryland, Michigan, Mississippi, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Puerto Rico, Rhode Island, South Dakota, Virginia, Washington, Washington, D.C. and West Virginia. A few jurisdictions have enacted laws authorizing sports betting in retail locations but have yet to begin operations in those jurisdictions. The jurisdictions with statutes legalizing iGaming are Connecticut, Delaware, Michigan, New Jersey, Pennsylvania and West Virginia. As of September 30, 2021, the Company operates online Sportsbooks in Arizona, Colorado, 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, Mississippi, New Hampshire, New Jersey and New York. As of September 30, 2021, the Company offers iGaming products in 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 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. The suspension of sports seasons and sporting events reduced customers’ use of, and spending on, the Company’s Sportsbook and DFS product offerings. 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 nine months ended September 30, 2021, many sports seasons continued and most sporting events were held as planned, including the NFL regular season, the NFL Playoffs and Superbowl LV, 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 continued 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. DraftKings is also developing more innovative products that do not rely on traditional sports seasons and sporting events, for example, products that permit wagering and contests on events such as eSports and simulated NASCAR. 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 These unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States (“U.S. GAAP”) for interim reporting. Accordingly, certain notes or other information that are normally required by U.S. GAAP have been omitted if they substantially duplicate the disclosures contained in the Company’s annual audited consolidated financial statements. Accordingly, the unaudited condensed consolidated financial statements should be read in connection with the Company’s audited financial statements and related notes as of and for the fiscal year ended December 31, 2020, which are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 as filed with the SEC on February 26, 2021 (“Original Annual Report”) and as amended by the Form 10-K/A filed with the SEC on May 3, 2021 (“2020 Annual Report”). The accompanying condensed consolidated financial statements are unaudited; however, in the opinion of management, they include all normal and recurring adjustments necessary for a fair presentation of the Company’s condensed consolidated financial statements for the periods presented. Results of operations reported for interim periods are not necessarily indicative of results for the entire year, due to seasonal fluctuations in the Company’s revenue as a result of timing of the various sports seasons, sporting events and other factors. As the Company completed its acquisition of SBTech on April 23, 2020, the presented financial information for the nine months ended September 30, 2021 includes the financial information and activities for SBTech; whereas, the financial information for the nine months ended September 30, 2020 includes the financial information and activities for SBTech for the period from April 24, 2020 to (and including) September 30, 2020. The accompanying unaudited condensed consolidated financial statements include the accounts and operations of the Company. All intercompany balances and transactions have been eliminated. Certain amounts from a prior period, which are not material, have been reclassified to conform with the current period presentation. 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 condensed 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 condensed consolidated statement of cash flows line items after giving effect to the revision of presentation as discussed above for the nine months ended September 30, 2020. For the effect to the revision of presentation for the six months ended June 30, 2020, year ended December 31, 2020 and three months ended March 31, 2021, refer to the Company’s Form 10-Q for the quarter ended June 30, 2021 filed with the SEC on August 6, 2021.

Cash and cash equivalents Cash and cash equivalents consist of highly liquid, unrestricted savings, checking and other bank accounts. The Company also utilizes money market funds and short-term deposits with original maturities of three months or less. 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 5 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.

Current and Long-term Liabilities	9 Months Ended

Current and Long-term Liabilities
Current and Long-term Liabilities	Current and Long-term Liabilities Convertible Notes 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”). In connection with the issuance of the Convertible Notes, the Company incurred $17.0 million of lender fees and $1.0 million of debt financing costs. The Convertible Notes represent senior unsecured obligations of the Company. The Convertible Notes will mature on March 15, 2028, subject to earlier conversion, redemption or repurchase. 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 the nine months ended September 30, 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. Revolving Line of Credit In October 2016, Old DK 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 September 30, 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 as of September 30, 2021 or December 31, 2020. Net facility available from the Credit Agreement as of September 30, 2021 and December 31, 2020 totaled $55.8 million, which, in each case, excludes the letters of credit outlined in Note 12. 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 Reports on Form 10-K and Quarterly Reports on Form 10-Q for the material weakness identified in Item 4. Controls and Procedures. 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 September 30, 2021 and December 31, 2020, the Company’s estimated contingent liability for indirect taxes was $43.4 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 condensed 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 September 30, 2021, there were no Public Warrants outstanding. As of September 30, 2021, 1.7 million Private Warrants remained outstanding at a fair value of $63.8 million. Due to fair value changes throughout the three and nine months ended September 30, 2021, the Company recorded a gain on remeasurement of warrant liabilities of $7.1 million and a loss on the remeasurement of warrant liabilities of $2.9 million, respectively, and a loss on remeasurement of warrant liabilities of $47.9 million and $411.3 million for the three and nine months ended September 30, 2020, respectively. In addition, 0.2 million Private Warrants were exercised during the nine months ended September 30, 2021, resulting in a reclassification to additional paid-in-capital in the amount of $5.2 million, reflecting the reclassification of the warrant liabilities of $4.5 million and proceeds upon exercise of $0.7 million.

Stock-Based Compensation	Stock-Based CompensationThe Company, historically, has issued three types of stock-based compensation: Time-Based awards, Long Term Incentive Plan (“LTIP”) awards and Performance-Based Stock Compensation Plan (“PSP”) awards. Time-Based awards are equity awards which generally vest over a 4-year period.

Income Taxes	Income Taxes The Company's provision for income taxes for the three and nine months ended September 30, 2021 and 2020 is as follows: Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 Income tax provision (benefit) $ 3,845 $ (13) $ 1,654 $ 319 The effective tax rates for the three months ended September 30, 2021 and 2020 were (0.71)% and 0.00%, respectively and the effective tax rates for the nine months ended September 30, 2021 and 2020 were (0.14)% and (.03)%, respectively. The difference between the Company’s effective tax rates for the three and nine month periods in 2021 and 2020 and the U.S. statutory tax rate of 21% was primarily due to a full valuation allowance related to the Company’s net U.S. deferred tax assets, offset partially by current state tax, current foreign tax, and current tax expense related to unrecognized tax benefits.

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 Company’s B2C segment is primarily comprised of the Old DK business and the Company’s B2B segment, which is primarily comprised of SBTech. 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. 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. 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: Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 Revenue: B2C $ 189,094 $ 103,651 $ 740,113 $ 248,170 B2B 23,725 29,185 82,587 44,139 Total revenue 212,819 132,836 822,700 292,309 Adjusted EBITDA: B2C (307,700) (201,455) (541,313) (304,889) B2B (5,903) 4,376 (6,854) 854 Total adjusted EBITDA (313,603) (197,079) (548,167) (304,035) Adjusted for: Depreciation and amortization 30,356 26,595 88,600 49,967 Interest (income) expense, net 1,556 (686) (1,071) 2,253 Income tax provision (benefit) 3,845 (13) 1,654 319 Stock-based compensation 175,664 117,034 499,246 176,362 Transaction-related costs 4,348 3,585 15,261 34,492 Litigation, settlement and related costs 4,712 2,419 8,933 5,771 Advocacy and other related legal expenses 16,667 — 27,702 — (Gain) loss on remeasurement of warrant liabilities (7,091) 47,908 2,905 411,269 Other non-recurring costs, special project costs and non-operating costs 1,368 1,740 5,501 4,671 Net loss attributable to common shareholders $ (545,028) $ (395,661) $ (1,196,898) $ (989,139) Due to the timing of the Business Combination, the three and nine month period ended September 30, 2020 reflects B2B/SBTech activity beginning April 24, 2020.

The MPA was amended to extend through 2021. The annual commitment for calendar years 2017 through 2021 was $15 million per year, plus an additional contingent commitment of $5 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 million in the aggregate through December 31, 2021 (equivalent to $5 million per year) and the contingent commitment was removed. As the Company has satisfied its $15.0 million commitment, the MPA has expired. The Company recorded expense of $0.0 million related to the MPA for the three and nine months ended September 30, 2021 and recorded expense of $7.7 million and $11.1 million related to the MPA for the three and nine months ended September 30, 2020, respectively in sales and marketing expenses in the consolidated statements of operations.

The Company’s lease agreements have terms not exceeding ten years. The components of lease cost are as follows: Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 Operating lease cost $ 4,207 $ 4,460 $ 12,569 $ 10,398 Short term lease cost 1,051 692 1,918 1,843 Variable lease cost 1,008 684 2,691 2,782 Sublease income (340) (421) (544) (1,242) Total lease cost $ 5,926 $ 5,415 $ 16,634 $ 13,781 Other information related to leases are as follows: Nine months ended September 30, 2021 2020 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows used by operating leases $ 13,393 $ 8,058 Right-of-use assets obtained in exchange for new operating lease liabilities $ 3,055 $ 36,777 The weighted-average remaining lease term and weighted-average discount rate for the Company’s operating leases were 6.0 years and 6.5% as of September 30, 2021.

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. Once the settlement agreement becomes effective, the only remaining plaintiffs will be the family member plaintiffs and the plaintiff who asserted the concerned citizen claim (referenced directly above). 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 has 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 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 is seeking, among other things, to compel arbitration against DraftKings on behalf of nine hundred ninety-nine (999) individuals. The Company has established an accrual for this matter. On August 7, 2021, DraftKings entered into a confidential 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 offering 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 offering infringes another patent. 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. The Court is currently deliberating who will be appointed lead plaintiff and lead counsel. 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, a putative shareholder derivative action was filed in the U.S. District Court for the District of Nevada by an alleged shareholder of the Company. The complaint purports 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. The complaint contends 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 also purports to assert claims on behalf of the Company for breach of fiduciary duty and corporate waste against all individual defendants arising out of the same the allegations concerning SBTech that were contained in the Hindenburg Report. 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 this matter or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss. Because this action alleges claims on behalf of the Company and purports to seeks a judgment in favor of the Company, 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. 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. 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 September 30, 2021 and December 31, 2020 for the Company’s leases of office space.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation These unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States (“U.S. GAAP”) for interim reporting. Accordingly, certain notes or other information that are normally required by U.S. GAAP have been omitted if they substantially duplicate the disclosures contained in the Company’s annual audited consolidated financial statements. Accordingly, the unaudited condensed consolidated financial statements should be read in connection with the Company’s audited financial statements and related notes as of and for the fiscal year ended December 31, 2020, which are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 as filed with the SEC on February 26, 2021 (“Original Annual Report”) and as amended by the Form 10-K/A filed with the SEC on May 3, 2021 (“2020 Annual Report”). The accompanying condensed consolidated financial statements are unaudited; however, in the opinion of management, they include all normal and recurring adjustments necessary for a fair presentation of the Company’s condensed consolidated financial statements for the periods presented. Results of operations reported for interim periods are not necessarily indicative of results for the entire year, due to seasonal fluctuations in the Company’s revenue as a result of timing of the various sports seasons, sporting events and other factors. As the Company completed its acquisition of SBTech on April 23, 2020, the presented financial information for the nine months ended September 30, 2021 includes the financial information and activities for SBTech; whereas, the financial information for the nine months ended September 30, 2020 includes the financial information and activities for SBTech for the period from April 24, 2020 to (and including) September 30, 2020.
Reclassification	Certain amounts from a prior period, which are not material, have been reclassified to conform with the current period presentation. 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 condensed 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.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents consist of highly liquid, unrestricted savings, checking and other bank accounts. The Company also utilizes money market funds and short-term deposits with original maturities of three months or less.
Recently Adopted Accounting Pronouncements	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 5 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.
