Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Description of Business DoorDash, Inc. (the “Company”), is incorporated in Delaware with headquarters in San Francisco, California. The Company provides a local logistics platform that enables local businesses to address consumers’ expectations of ease and immediacy and thrive in today’s convenience economy. The Company’s local logistics platform connects merchants, consumers, and Dashers. The Company operates the DoorDash Marketplace, which enables merchants to establish an online presence and expand their reach by connecting them with consumers (the “Marketplace”). Merchants can fulfill this demand with independent contractors who use the Company’s platform to deliver orders (“Dashers”). As part of the Marketplace, the Company also offers Pickup, which allows consumers to place advance orders, skip lines, and pick up their orders conveniently with no consumer fees, as well as DoorDash for Work, which provides merchants on the Company’s platform with large group orders and catering orders for businesses and events. The Marketplace also includes DashPass, the Company’s membership product, which was formerly referred to the Company's subscription product, which provides consumers with unlimited access to eligible merchants with zero delivery fees and reduced service fees. In addition to the Marketplace, the Company offers Platform Services, which primarily includes DoorDash Drive ("Drive"), a white-label logistics service that enables merchants that have generated consumer demand through their own channels to fulfill this demand using the Company’s local logistics platform, and DoorDash Storefront ("Storefront") that enables merchants to create their own branded online ordering experience, providing them with a turnkey solution to offer consumers on-demand access to e-commerce without investing in in-house engineering or logistics capabilities. Initial Public Offering On December 9, 2020, the Company completed its initial public offering ("IPO") in which it issued and sold 33 million shares of its Class A common stock at the public offering price of $102.00 per share. The Company received net proceeds of $3.3 billion after deducting underwriting discounts and commissions and offering costs. Immediately prior to the completion of the IPO, all shares of the Company’s outstanding redeemable convertible preferred stock automatically converted into 239 million shares of its common stock. Additionally, immediately prior to the completion of the IPO, the Company filed its Amended and Restated Certificate of Incorporation, which authorizes a total of 6.0 billion shares of Class A common stock, 200 million shares of Class B common stock, 2.0 billion shares of Class C common stock, and 600 million shares of preferred stock. Upon the filing of the Amended and Restated Certificate of Incorporation, 285 million shares of the Company’s common stock were automatically reclassified into an equivalent number of shares of the Company’s Class A common stock (the “Reclassification”). Immediately after the Reclassification and prior to the completion of the IPO, a total of 31 million shares of Class A common stock held by Tony Xu, Andy Fang, Stanley Tang, and their respective affiliated trusts were exchanged for an equivalent number of shares of Class B common stock pursuant to the terms of certain exchange agreements. As a result, following the completion of the IPO, the Company has three classes of authorized common stock: Class A common stock, Class B common stock, and Class C common stock, of which Class A common stock and Class B common stock were outstanding as of December 31, 2020 and 2021. The Company granted certain employees restricted stock units (“RSUs”) with both service-based and liquidity event-related performance vesting conditions ("IPO Vested RSUs"). Upon the consummation of the Company’s IPO, the Company recognized $279 million of stock-based compensation expense for IPO Vested RSUs as the performance vesting condition was satisfied. One share of Class A common stock for each of the IPO Vested RSUs was settled and delivered on June 7, 2021 (the “IPO Vested RSU Settlement Date”). The future tax benefits on settlement of the above RSUs is not expected to be material as currently the Company has established valuation allowances to reduce its net deferred tax assets to the amount that is more likely than not to be realized. To meet the related tax withholding requirements related to IPO Vested RSUs, for stockholders who elected to net share settle, the Company withheld 65,058 shares of Class A common stock subject to the vesting of the IPO Vested RSUs and paid $7 million to the relevant tax authorities in cash to satisfy such tax obligations as well as any income tax withholding obligations arising as a result of settlement of such shares. Certain employees elected to receive a short-term loan from the Company, with interest that accrued at the applicable federal rate. The short-term loan extended to employees totaled $10 million, which was repaid from the proceeds of the sale of shares into the market on the IPO Vested RSU Settlement Date. Stock Splits In November 2020, the Company’s board of directors and the stockholders of the Company approved a five-for-one forward stock split of the Company’s common stock and redeemable convertible preferred stock (collectively, the “Capital Stock”), which became effective on November 9, 2020. The authorized number of each class and series of Capital Stock was proportionally increased in accordance with the five-for-one stock split and the par value of each class of Capital Stock was not adjusted as a result of this forward stock split. All common stock, redeemable convertible preferred stock, stock options, RSUs, warrants, and per share information presented within these consolidated financial statements have been adjusted to reflect this forward stock split on a retroactive basis for all periods presented.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany transactions have been eliminated in consolidation. Segments Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one reportable segment. See Note 3 for revenue by geography. Long-lived assets, which consist of property and equipment, net and operating lease right-of-use assets, located outside of the United States were $15 million and $28 million a s of December 31, 2020 and 2021, respectively. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the period presented. Estimates include, but are not limited to, revenue recognition, allowances for credit losses, gift card breakage, estimated useful lives of property and equipment, capitalized software and website development costs, intangible assets, stock-based compensation, valuation of investments and other financial instruments, valuation of acquired intangible assets and goodwill, the incremental borrowing rate applied in lease accounting, insurance reserves, loss contingencies, and income and indirect taxes. Actual results could differ from these estimates. Business Combinations The Company accounts for business combinations using the acquisition method of accounting, which requires, among other things, allocation of the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed at their estimated fair values on the acquisition date. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to the valuation of intangible assets. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, the Company may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill if new information is obtained related to facts and circumstances that existed as of the acquisition date. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are reflected in the consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred. Cash, Cash Equivalents, and Restricted Cash Cash includes demand deposits with banks or financial institutions as well as cash in transit from payment processors. Cash equivalents include short-term, highly liquid investments with original maturities of three months or less and their carrying values approximate fair value due to their short-term maturities. Restricted cash consists of collateral provided for letters of credit established primarily for real estate leases and insurance policies. As of December 31, 2020 and 2021, the restricted cash balances were not material and were included in other assets on the consolidated balance sheets. Marketable Securities Marketable securities primarily consist of commercial paper, U.S. government agency securities, U.S. Treasury securities, and corporate bonds. The Company invests in a diversified portfolio of marketable securities and limits the concentration of its investment in any particular security. Securities with maturities greater than three months, but less than one year, are included in current assets and securities with maturities greater than one year are included in non-current assets on the consolidated balance sheets. All marketable securities are classified as available-for-sale and reported at fair value. If the estimated fair value of an available-for-sale debt security is below its amortized cost basis, then the Company evaluates the security for impairment. The Company considers its intent to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized basis. If either of these criteria are met, the debt security’s amortized cost basis is written down to fair value through other income (expense), net in the consolidated statements of operations. If neither of these criteria are met, the Company evaluates whether unrealized losses have resulted from a credit loss or other factors. The factors considered in determining whether a credit loss exists can include the extent to which fair value is less than the amortized cost basis, changes to the rating of the security by a rating agency, any adverse conditions specifically related to the security, as well as other factors. An impairment relating to credit losses is recorded through an allowance for credit losses reported in other income (expense), net in the consolidated statements of operations. The allowance is limited by the amount that the fair value of the debt security is below its amortized cost basis. When a credit loss exists, the Company compares the present value of cash flows expected to be collected from the debt security with the amortized cost basis of the security to determine what allowance amount, if any, should be recorded. As of December 31, 2020 and 2021, no allowance of credit losses related to marketable securities was recorded. Unrealized losses not resulting from credit losses are recorded through accumulated other comprehensive income (loss). Funds Held at Payment Processors Funds held at payment processors represent cash due from the Company’s payment processors for transactions with merchants and consumers, as well as funds transferred to payment processors for Dasher payout. Accounts Receivable, Net and Allowance for Credit Losses Accounts receivable, net primarily represents receivables from merchants that were generated through the Company’s Drive offering. The Company maintains an allowance for credit losses, which is based on the Company’s assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for credit losses on a collective basis by considering the age of each outstanding invoice, each customer’s expected ability to pay and collection history, current market conditions, and reasonable and supportable forecasts of future economic conditions to determine whether the allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for credit losses when identified. Property and Equipment, Net Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. The useful lives are as follows: Estimated Useful Life Equipment for merchants 2 years Computer equipment and software 2 years Office equipment 5 years Capitalized software and website development costs 2 years Leasehold improvements Shorter of estimated useful life or lease term Maintenance and repair costs are charged to expense as incurred. Upon disposal of a fixed asset, the Company records a gain or loss based on the difference between the proceeds received and the net book value of the disposed asset. Disposals were not material for the years ended December 31, 2019, 2020 and 2021. Intangible Assets, Net Intangible assets are recorded at fair value as of the date of acquisition and amortized on a straight-line basis over their estimated useful lives. The Company reviews identifiable amortizable intangible assets for impairment under the long-lived asset model described under “Impairment of Long-Lived Assets” below. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized, but is tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s impairment tests are based on a single operating segment and reporting unit structure. If the carrying value of the reporting unit exceeds its fair value, an impairment charge is recognized for the excess of the carrying value of the reporting unit over its fair value. The Company conducted its annual goodwill impairment test during the fourth quarter of 2021 and determined that the fair value of the reporting unit significantly exceeded its carrying value. No impairment charge was recorded in any of the periods presented in the accompanying consolidated financial statements. Non-Marketable Equity Securities Non-marketable equity securities which the Company does not have a controlling financial interest in and does not exercise significant influence over the investee are recorded at cost and adjusted for observable transactions for same or similar investments of the same issuer (referred to as the measurement alternative) or impairment. The carrying value is not adjusted for the Company’s non-marketable equity securities if there are no observable price changes in a same or similar security from the same issuer or if there are no identified events or changes in circumstances that may indicate impairment. In 2021, the Company made investments in non-marketable equity securities of $409 million in cash for preferred shares of private companies including an investment of $395 million in cash for preferred shares of a grocery delivery platform company. All those investments were accounted for using the measurement alternative. There are no adjustments or impairment associated with the Company’s non-marketable equity securities during 2021. The Company does not have any realized or unrealized gains or losses on non-marketable equity securities as of and for the years ended December 31, 2020 and 2021. Capitalized Software and Website Development Costs The Company incurred costs relating to the development of the Company’s technology platform, which includes Dasher and merchant tools, mobile apps, and website and content development. Software development costs related to software acquired, developed, or modified solely to meet the Company’s internal requirements, with no substantive plans to market such software at the time of development, are capitalized during the application development stage of the project. Costs incurred during the preliminary planning and evaluation stage of the project and during the post implementation operational stage are expensed as incurred. Costs to develop the Company’s technology platform are capitalized when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Costs incurred for enhancements that are expected to result in additional functionality are capitalized and expensed over the estimated useful life of the upgrades on a per project basis. Impairment of Long-Lived Assets The Company evaluates its long-lived assets or asset groups for indicators of possible impairment by comparison of the carrying amount to future net undiscounted cash flows expected to be generated by such asset or asset group when events or changes in circumstances indicate the carrying amount of an asset or asset group may not be recoverable. Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset or asset group over the asset’s or asset group’s fair value generally determined by estimates of future discounted cash flows. Assets to be disposed of are reported at the lower of their carrying amount or fair value less costs to sell. During the years ended December 31, 2020 and 2021, the Company recognized impairment charges of $11 million and $1 million, respectively, related to an operating lease right-of-use asset associated with its former headquarters, which the Company subleased to another company. Insurance Reserves The Company utilizes third-party insurance which include retained insurance deductibles to insure costs including auto liability related to both bodily injury and physical damage, and uninsured and underinsured motorists up to a certain dollar retention limit. The recorded insurance reserves reflect the estimated cost for claims incurred but not paid and claims that have been incurred but not yet reported. The estimate of the Company’s ultimate deductible obligation utilizes actuarial techniques applied to historical claim and loss experience. Given our limited operational history, the Company utilizes assumptions based on actuarial judgments with consideration toward relevant industry claim and loss development factors, which includes the development time frame and settlement patterns, and expected loss rates. Reserves are periodically reviewed and adjusted as necessary as experience develops or new information becomes known. However, ultimate results may differ from the Company’s estimates, which could result in losses over the Company’s reserved amounts. During the years ended December 31, 2019, 2020 and 2021, the Company recorded additions to the insurance reserves of $12 million, $63 million and $134 million, respectively. Loss Contingencies The Company is involved in various lawsuits, claims, investigations, and proceedings that arise in connection with its business. Certain of these matters include speculative claims for substantial or indeterminate amounts of damages. The Company records a liability in accrued expenses and other current liabilities on the consolidated balance sheets when the Company believes that it is both probable that a loss has been incurred and the amount or range can be reasonably estimated. The Company discloses material contingencies when it believes that a loss is not probable but reasonably possible. Significant judgment is required to determine both probability and the estimated amount. The Company reviews these provisions on a quarterly basis and adjusts these provisions accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Sales and Indirect Taxes The Company records sales and indirect tax liabilities when they become probable and the amount can be reasonably estimated. Sales and indirect tax liabilities are included in accrued expenses and other current liabilities on the consolidated balance sheets. Accumulated Other Comprehensive Income (Loss) Accumulated other comprehensive income (loss) consists of foreign currency translation adjustments and unrealized gains and losses on available-for-sale marketable securities. The financial statements of the Company’s foreign subsidiaries are translated from their functional currency, which is typically the local currency, into U.S. dollars. Assets and liabilities are translated at period end rates of exchange, and revenue and expenses are translated using average monthly exchange rates. The resulting gain or loss is included in accumulated other comprehensive income (loss) on the consolidated balance sheets. Available-for-sale securities are reported at fair value, with unrealized gains and losses included as a separate component of stockholders’ equity within accumulated other comprehensive income (loss). Stock-Based Compensation The fair value of RSUs is estimated based on the fair value of the Company’s common stock on the date of grant. Prior to November 2020, RSUs granted by the Company vest upon the satisfaction of both a service-based vesting condition, which is typically four years, and a liquidity event-related performance vesting condition. The liquidity event-related performance vesting condition was achieved upon the consummation of the Company's IPO, and the Company recorded a cumulative stock-based compensation expense of $279 million as of the IPO date for those RSUs for which the service-based vesting condition has been satisfied. Stock-based compensation related to the remaining service-based period after the liquidity event-related performance vesting condition was satisfied will be recorded over the remaining requisite service period using the accelerated attribution method. Since November 2020, with the exception of the CEO Performance Award (as discussed further in Note 12), the Company only granted RSUs that vest upon the satisfaction of a service-based vesting condition and the compensation expense for these RSUs is recognized on a straight-line basis over the requisite service period. For the CEO Performance Award (as defined below) that includes a market condition, the fair value of the award was determined using a Monte Carlo simulation model. The associated stock-based compensation is recorded over the derived service period, using the accelerated attribution method. If the stock price goals are met sooner than the derived service period, the Company will adjust the stock-based compensation expense to reflect the cumulative expense associated with the vested award. Provided that Tony Xu continues to be the Chief Executive Officer of the Company, stock-based compensation expense is recognized over the requisite service period, regardless of whether the stock price goals are achieved. Prior to the IPO, the fair value of the shares of common stock underlying the stock options and RSUs has historically been determined by the Company’s board of directors as there is no public market for the underlying common stock. The Company’s board of directors determined the fair value of the Company’s common stock by considering a number of objective and subjective factors including: contemporaneous third-party valuations of its common stock, the valuation of comparable companies, sales of the Company’s common and redeemable convertible preferred stock to outside investors in arms-length transactions (including the IPO), the Company’s operating and financial performance, the lack of marketability, and the general and industry specific economic outlook, amongst other factors. After the completion of the IPO, the fair value of the Company's Class A common stock is determined based on the New York Stock Exchange ("NYSE") closing price on the date of grant. The Company records forfeitures when they occur for all share-based payment awards. Provision for Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred income tax assets and liabilities are recorded based on the estimated future tax effects of differences between the financial statement and income tax basis of existing assets and liabilities. These differences are measured using the enacted statutory tax rates that are expected to apply to taxable income for the years in which differences are expected to reverse. The Company recognizes the effect on deferred income taxes of a change in tax rates in the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets to the net amount that it believes is more-likely-than-not to be realized. Management considers all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income, and ongoing tax planning strategies in assessing the need for a valuation allowance. The Company operates in various tax jurisdictions and is subject to audit by tax authorities. The Company recognizes the tax benefit of an uncertain tax position only if it is more-likely-than-not that the position is sustainable upon examination by the taxing authority, based on the technical merits. The tax benefit recognized is measured as the largest amount of benefit which is greater than 50% likely to be realized upon settlement with the taxing authority. The Company recognizes interest accrued and penalties related to unrecognized tax benefits in the provision for income taxes. Fair Value The Company measures certain assets and liabilities at fair value on a recurring basis based on an expected exit price, which represents the amount that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis, whereby inputs used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value: Level 1 Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 Unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. The carrying amounts of certain of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable, and accrued expenses and other current liabilities approximate their fair values due to their short maturities. Concentration of Credit Risk The Company’s cash, cash equivalents, marketable securities, funds held at payment processors, and accounts receivable are potentially subject to concentration of credit risk. Although the Company deposits its cash with multiple financial institutions, the deposits, at times, may exceed federally insured limits. Management believes that the institutions are financially stable and, accordingly, minimal credit risk exists. The Company limits purchases of debt securities to investment-grade securities. The Company has not experienced any significant credit losses historically. The Company relies on a limited number of third parties to provide payment processing services (“payment processors”) including collecting amounts due from end-users and processing Dasher payouts. Payment processors are financial institutions or credit card companies that the Company believes are of high credit quality. The Company retains the risk of collecting such amounts from the payment processors, which are included in funds held at payment processors for the unsettled portion at each period end. The portion of the payments to be remitted to Dashers and merchants is included in accrued expenses and other current liabilities. Although the Company pre-authorizes forms of payment to mitigate its exposure, the Company absorbs all credit card losses. Accounts receivable, net primarily represents receivables from merchants that were generated through the Company’s Drive offering. As of December 31, 2020, three entities in dividually accounted for 20%, 14%, and 10% of accounts receivable, net, respectively. As of December 31, 2021, two entities in dividually accounted for 15% and 14% of accounts receivable, net, respectively. No customer accounted for 10% or more of revenue for the years ended December 31, 2019, 2020, and 2021. Revenue Recognition The Company recognizes revenue in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with its Customers. The Company generates a substantial majority of its revenue from orders completed through the Marketplace and the related commissions charged to partner merchants and fees charged to consumers. A partner merchant represents a merchant that has entered into a contractual agreement with the Company. Revenue from the Marketplace is recognized at the point in time when the consumer obtains control of the merchant’s products. The Company also generates revenue from membership fees paid by consumers for DashPass, which is recognized as part of the Marketplace. Revenue generated from the Company’s DashPass memberships is recognized on a ratable basis over the contractual period, which is generally one month to one year depending on the type of membership purchased by the consumer. In addition, the Company also generates revenue from its Drive offering by collecting per-order fees from merchants that use its local logistics platform to arrange for delivery services that fulfill demand generated through their own channels. Revenue from Drive is recognized at the point in time when the consumer obtains control of the merchant’s products. When determining the appropriate accounting for the fees collected in exchange for the use of the Company’s local logistics platform, the Company considered its contractual arrangements with the parties involved as well as its customary business practices. Under the Company’s agreements with partner merchants, the Company agrees to a commission to be earned as a percentage of the total dollar value of goods ordered. When a consumer signs up to use the Company’s local logistics platform, the consumer agrees to be charged certain fees, at the time an order is placed, in exchange for use of the platform. The Company has concluded that a contract exists between the Company and a partner merchant when the partner merchant accepts each consumer’s order, and a contract exists between the Company and a consumer when the consumer places the order and requests delivery services. The duration of a contract is typically equal to the time between when the order is placed and a Dasher picks up the food from the merchant. Contracts including variable consideration with partner merchants were not material for the periods presented. The Company’s local logistics platform facilitates orders between consumers and partner merchants. Separately, the Company’s platform arranges for consumers to obtain delivery service from Dashers. The Company has determined that the order facilitation service and delivery facilitation service are distinct performance obligations and has therefore considered whether it is a principal or agent separately for each of these items. The order facilitation service and the delivery facilitation service are distinct given that the consumer can benefit from each item separately. Further, the order facilitation service and delivery facilitation service are separately identifiable as the nature of the promises are to transfer the order facilitation service and delivery facilitation service individually, rather than as a combined item. Principal vs. Agent Considerations Judgment is required in determining whether the Company is the principal or the agent in transactions with partner merchants, consumers, and Dashers. As it relates to the accounting for order facilitation services and delivery facilitation services, the Company evaluated whether to present revenue on a gross versus net basis based on whether it controls each specified good or service before it is provided to the consumer in Marketplace transactions. With respect to order facilitation services, the Company has determined it is an agent for partner merchants in facilitating the sale of products to the consumer through the Marketplace. The consumer accesses the Company’s local logistics platform to identify merchants and places an order for merchants’ products. These orders are picked up from partner merchants and delivered to consumers by Dashers. The Company does not control the products prior to them being transferred to the consumer as it neither has the ability to redirect the products to another consumer nor does it obtain any economic benefit from the products. With respect to the vast majority of its delivery facilitation services, the Company has determined it is acting as an agent for the consumer in facilitating the delivery of products by connecting consumers with Dashers. As the Company’s role with the delivery facilitation service is only to arrange for a delivery opportunity to be offered to prospective Dashers, it does not control how the delivery service is ultimately provided to the consumer. In the vast majority of its transactions with end-users, the Company is an agent in facilitating the sale of products and delivery services, thus the Company reports revenue on a net basis, reflecting amounts collected from consumers, less amounts remitted to merchants and Dashers. Dasher payout represents the amounts paid to Dashers for deliveries, including incentives and tips, except for certain referral bonuses. From time to time, Dashers may request an earlier payment settlement in exchange for a reduction in Dasher payout. The amounts payable to merchants and Dashers are included in accrued expenses and other current liabilities on the consolidated balance sheets as payments are typically settled on a weekly basis. The Company recognizes revenue from both partner merchants and consumers for each successfully completed transaction. The Company satisfies its performance obligations to a partner merchant when there is a successful sale of the merchant’s products and meets its performance obligation to a consumer once the Dasher has picked up the products from the merchant for delivery to the consumer. The Company also provides value-add services to merchants. These services are generally considered separate performance obligations and revenue is recognized over the period in which services are provided. Revenue generated from such services is not material in all periods presented. Gift Cards The Company sells gift cards to consumers that can be redeemed through the Marketplace. Those gift cards have no expiration date and administrative fees are not charged on unused gift cards. In prior periods, with limited history as to consumers' redemption patterns, proceeds from the sale of gift cards were fully deferred and recorded as contract liabilities until consumers used the card to place orders on its platform. When gift cards are redeemed, revenue is recognized on a net basis as the difference between the amounts collected from consumers less amounts remitted to merchants and Dashers. During the year ended December 31, 2021, the Company concluded that it had developed sufficient historical evidence regarding the pattern of consumer redemptions of gift cards to have the ability to estimate the portion of outstanding gift cards that will never be redeemed (“breakage”) and for which there is no legal obligation to remit the value of the unredeemed gift cards to the relevant jurisdiction as unclaimed or abandoned property. The Company recognizes the breakage amounts as revenue, proportionate to the pattern of revenue recognition for the gift card redemptions. As a result of this change in estimate, the Company recorded $48 million of gift card breakage revenue during the year ended December 31, 2021. Estimating future breakage rates requires judgment based on current and historical patterns of redemption, and the actual breakage rates may vary from the estimate. Refunds and Credits From time to time the Company issues credits or refunds to merchants and consumers to ameliorate issues that may arise with orders. The Company accounts for such refunds as variable consideration and therefore r

Revenue by geographic area is determined based on the address of the merchant, or in the case of DashPass, the address of the consumer. Revenue by geographic area was as follows (in millions): Year Ended December 31, 2019 2020 2021 United States $ 877 $ 2,875 $ 4,877 International 8 11 11 Total revenue $ 885 $ 2,886 $ 4,888 Contract Liabilities The timing of revenue recognition may differ from the timing of invoicing to or collections from customers. The Company’s contract liabilities balance, which is included in accrued expenses and other current liabilities on the consolidated balance sheets, is primarily comprised of unredeemed gift cards, prepayments received from consumers and merchants, certain consumer credits as well as other transactions for which the revenue is recognized over time. A summary of activities related to contract liabilities for the year ended December 31, 2021 was as follows (in millions): Year Ended December 31, 2021 Beginning balance $ 108 Addition to contract liabilities 1,212 Reduction of contract liabilities (1)(2)(3) (1,137) Ending balance $ 183 (1) Gift cards and certain consumer credits can be redeemed through the Marketplace. When they are redeemed, revenue is recognized on a net basis as the difference between the amounts collected from consumers less amounts remitted to merchants and Dashers for those transactions. Therefore, the amount recognized as revenue related to the reduction of gift cards and certain consumer credits is less than the amount presented in the table above. Net revenue associated with gift cards and certain consumer credits is not tracked by the Company as it is impracticable to do so. (2) Included in the beginning balance of contract liabilities was $22 million associated with unearned prepayments received by the Company, all of which was recognized as revenue during the year ended December 31, 2021. (3) During the year ended December 31, 2021, the Company recorde d $48 million o f gift card breakage revenue, which represented the estimate of cumulative gift card breakage through December 31, 2021 based on the Company's accounting policy discussed in Note 2. Deferred Contract Costs Deferred contract costs represent direct and incremental costs incurred to acquire or fulfill the Company’s contracts, consisting of sales commissions and costs related to merchant onboarding, which the Company expects to recover. Deferred contract costs are amortized on a straight-line basis over the expected period of benefit, which the Company determined by considering historical attrition rates and other factors. Deferred contract costs are recorded in prepaid expenses and other current assets and other assets on the consolidated balance sheets. Amortization of deferred contract costs related to sales commissions is recognized in sales and marketing expense and amortization of deferred contract costs related to merchant onboarding is recognized in cost of revenue, exclusive of depreciation and amortization in the consolidated statements of operations.

Leases [Abstract]
Leases	Leases The Company leases its facilities under non-cancelable lease agreements which expire between 2022 and 2035. Certain of these arrangements have free rent, escalating rent payment provisions, lease renewal options, and tenant allowances. Under such arrangements, the Company recognizes a ROU asset and lease liability on the consolidated balance sheets. Lease costs are recognized on a straight-line basis over the non-cancelable lease term. Lease costs, net of sublease income, was $29 million, $46 million, and $66 million during the years ended December 31, 2019, 2020, and 2021, respectively. In June 2019, the Company subleased its previous headquarters office space to another company (the “Sublessee”). The sublease required Sublessee to pay 100% of any rent and other related expenses due and payable under the existing lease with the landlord (the “Head Lease”), however the Company was not relieved from its legal obligation to the landlord under the Head Lease. Accordingly, an operating lease liability and an operating lease ROU asset was reflected on the Company’s consolidated balance sheets related to the Head Lease. Prior to April 2020, all payments due and payable by Sublessee were made timely. In early April 2020, as a result of a disruption to Sublessee’s business due to the COVID-19 pandemic, Sublessee informed the Company that it would not be making any future monthly rent payments. Accordingly, the Company ceased recognizing sublease income beginning in April 2020, and further determined that an impairment existed and recognized an impairment charge of $11 million and $1 million for the year ended December 31, 2020 and 2021, respectively, reducing the carrying value of the ROU asset to its estimated fair value. Fair value of the ROU asset was estimated using an income-approach based on forecasted future cash flows expected to be derived from the property based on current sublease market rent. The components of lease costs related to the Company’s operating leases included in the consolidated statements of operations for the periods presented were as follows (in millions): Year Ended December 31, 2019 2020 2021 Operating lease cost $ 22 $ 40 $ 52 Short-term lease cost 10 11 17 Sublease income (3) (5) (3) Total lease cost $ 29 $ 46 $ 66 Lease terms and discount rates for operating leases were as follows: December 31, 2020 December 31, 2021 Weighted-average remaining lease term (in years) 10.7 9.77 Weighted-average discount rate 8.06% 6.81% Supplemental cash flow and non-cash information was as follows (in millions): Year Ended December 31, 2020 2021 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows for operating leases $ 32 $ 46 ROU assets obtained in exchange for new lease liabilities Operating leases $ 69 $ 164 As of December 31, 2020 and 2021, the Company had entered into long term non-cancelable real estate lease contracts of $120 million and $19 million, respectively, for which leases have not yet commenced. Such leases are not included in the operating lease ROU assets and operating lease liabilities on the consolidated balance sheets. As of December 31, 2021, the future minimum lease payments required under operating leases were as follows (in millions): Year Ending December 31, Amount 2022 $ 53 2023 65 2024 63 2025 60 2026 58 Thereafter 293 Total future minimum lease payments 592 Less: Lease not commenced (19) Less: Imputed interest (165) Less: Tenant improvement receivable (9) Present value of future minimum lease payments $ 399 Future minimum sublease income as of December 31, 2021 is $7 million.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings From time to time, the Company may be a party to litigation and subject to claims incidental to its business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these matters will not have a material adverse effect on its business. Regardless of the outcome, litigation can have an adverse impact on the Company because of judgment, defense and settlement costs, diversion of management resources, and other factors. At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable, requiring recognition of a loss accrual, or whether the potential loss is reasonably possible, requiring potential disclosure. Legal fees are expensed as incurred. The Company has been and continues to be involved in numerous legal proceedings related to Dasher classification, and such proceedings have increased in volume since the California Supreme Court’s 2018 ruling in Dynamex Operations West, Inc. v. Superior Court (“Dynamex”) . The California Legislature passed legislation (“AB 5”), that was signed into law in September 2019 and became effective on January 1, 2020. AB 5 codified the Dynamex standard regarding contractor classification, expanded its application and created numerous carve-outs, which may have an adverse effect on the Company’s business, financial condition, and results of operations, and may lead to increased legal proceedings and related expenses and may require the Company to significantly alter its existing business model and operations. Further, some jurisdictions are considering implementing standards similar to the test set forth in Dynamex to determine worker classification. The Company is currently the subject of regulatory and administrative investigations, audits, and inquiries conducted by federal, state, or local governmental agencies concerning the Company’s business practices, the classification and compensation of delivery providers, the Dasher pay model, and other matters. For example, the company is currently under audit by the Employment Development Department, State of California for payroll tax liabilities. The Company believes that Dashers are, and have been, properly classified as independent contractors, and thus plans to vigorously contest any adverse assessment or determination. The Company’s chances of success on the merits is uncertain. In October 2019, the Company made an offer, and in November 2019 it filed a settlement agreement, of $40 million with the representatives of Dashers that had filed actions in the States of California and Massachusetts in order to settle claims under the Private Attorney General Act and class action claims alleging worker misclassification of Dashers against the Company. These actions were filed by and on behalf of Massachusetts Dashers that utilized the DoorDash platform since September 2014 and California Dashers that utilized the DoorDash platform since August 2016. On June 8, 2020, the Company entered into an amended settlement agreement to increase the total amount to be paid by the Company from $40 million to $41 million. In October 2020, the Company entered into an amended settlement agreement to increase the total amount to be paid by the Company from $41 million to $89 million. In April 2021, the Company entered into an amended settlement agreement increasing the total amount to be paid by the Company to $100 million. In January 2022, the settlement received final approval and the company anticipates the payout of $100 million in 2022. In March 2020, the Company reached an agreement to resolve worker misclassification claims associated with certain Dashers and Caviar delivery providers who have entered into arbitration agreements with the Company. Under the agreement, certain Dashers and Caviar delivery providers were eligible for settlement payments, subject to a threshold number of the covered individuals entering into individual settlement agreements. In July 2020, the Company transferred $69 million into an escrow account to be paid to claimants and claimants’ attorneys if a minimum number of claimants agreed to release their claims against the Company by the date specified within the settlement agreement. In December 2020, the number of claimants who agreed to release their claims against the Company exceeded the minimum, and the Company was committed to release the settlement amount in the escrow account to claimants and claimants' attorneys. In the year ended December 31, 2021, the $69 million in the escrow account was fully distributed to the claimants and claimants' attorneys. In July and August 2020, the Company reached additional agreements to resolve worker misclassification claims associated with certain Dashers and Caviar delivery providers who have entered into arbitration agreements with the Company. Under these agreements, certain Dashers and Caviar delivery providers were eligible for settlement payments, subject to a threshold number of the covered individuals entering into individual settlement agreements. The aggregate amount of payments to Dashers and Caviar delivery providers under these individual settlement agreements, including attorneys’ fees, was $14 million, which was fully paid in the year ended December 31, 2021. In June 2020, the San Francisco District Attorney filed an action in the Superior Court of California, County of San Francisco, alleging that the Company misclassified Dashers as independent contractors as opposed to employees in violation of the California Labor Code and the California Unfair Competition Law, among other allegations. This action is seeking both restitutionary damages and a permanent injunction that would bar the Company from continuing to classify Dashers as independent contractors. It is a reasonable possibility that a loss may be incurred; however, the possible range of losses is not estimable given the status of the case. Indemnification The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent, or other intellectual property infringement claim by any third-party with respect to its technology. The terms of these indemnification agreements are generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future, but have not yet been made. The Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. The Company has entered into or will enter into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. No liability associated with such indemnifications was recorded as of December 31, 2020 and 2021. Non-cancelable Purchase Commitments The Company has non-cancelable purchase commitments, which primarily relate to the purchase of onboarding, data processing, technology platform infrastructure, and advertising services. These purchase commitments are not recorded as liabilities on the consolidated balance sheets as of December 31, 2020 and 2021 as the Company has not yet received the related services. As of December 31, 2021, the future minimum payments under the Company’s non-cancelable purchase commitments were as follows (in millions): Year Ending December 31, Amount 2022 $ 151 2023 152 2024 5 2025 3 Total future minimum payments $ 311 Revolving Credit Facility and Letters of Credit In November 2019, the Company entered into a revolving credit and guaranty agreement which provides for a $300 million unsecured revolving credit facility maturing on November 19, 2024. Loans under the credit facility bear interest, at the Company’s option, at (i) a base rate equal to the highest of (A) the prime rate, (B) the higher of the federal funds rate or a composite overnight bank borrowing rate plus 0.50%, or (C) an adjusted LIBOR rate for a one-month interest period plus 1.00%, or (ii) an adjusted LIBOR rate plus a margin equal to 1.00%. The Company is also obligated to pay other customary fees for a credit facility of this size and type, including letter of credit fees, an upfront fee, and an unused commitment fee of 0.10%. The credit agreement contains customary affirmative covenants, such as financial statement reporting requirements and restrictions on the use of proceeds, as well as customary negative covenants that restrict its ability and its subsidiaries’ ability to, among other things, incur additional indebtedness, incur liens, declare cash dividends in the entirety or make certain other distributions, merge or consolidate with other companies or sell substantially all of its assets, make investments, loans and acquisitions, and engage in transactions with affiliates. In August 2020, the Company amended and restated its existing revolving credit and guaranty agreement to provide for $100 million of incremental revolving loan commitments, effective upon consummation of an IPO of the Company’s common stock on or prior to August 7, 2021, for total revolving commitments of $400 million. The amendment and restatement also extended the maturity date for the revolving credit facility from November 19, 2024 to August 7, 2025. As of December 31, 2020 and 2021, the Company was in compliance with the covenants under the credit agreement. As of December 31, 2020 and 2021, no amounts were drawn from the credit facility. The Company maintains letters of credit established primarily for real estate leases and insurance policies. As of December 31, 2020 and 2021, the Company had $66 million and $60 million of issued letters of credit outstanding, respectively, of which $44 million and $39 million were issued from the revolving credit and guaranty agreement. Sales and Indirect Tax Matters The Company is under audit by various state and local tax authorities with regard to sales and indirect tax matters. The Company records sales and indirect tax reserves when they become probable and the amount can be reasonably estimated. These reserves are included in accrued expenses and other current liabilities on the consolidated balance sheets. The timing of the resolution of indirect tax examinations is highly uncertain, and the amounts ultimately paid, if

Temporary Equity Disclosure [Abstract]
Redeemable Convertible Preferred Stock	Redeemable Convertible Preferred Stock In June 2020, the Company entered into a Series H redeemable convertible preferred stock purchase agreement pursuant to which it issued a total of 8,321,395 shares of Series H redeemable convertible preferred stock at $45.9062 per share for gross proceeds of $382 million. The preferred stock issuance costs were not material. The Company previously issued Series A-1, Series A, Series B, Series C, Series D, Series E, Series F, and Series G prior to 2020. Immediately prior to the completion of the IPO on December 9, 2020, all outstanding shares of the Company’s redeemable convertible preferred stock converted into an aggregate of 239,269,631 shares of Class A common stock. The following table summarizes the redeemable convertible preferred stock outstanding immediately prior to the conversion into common stock, and the rights and preferences of the Company’s respective series preceding the Company’s IPO in December 2020 (in millions, except share amounts which are reflected in thousands, and per share data): Series Shares Shares Issuance Price Per Share Aggregate Carrying Series A-1 13,330 13,330 $ 0.15 $ 0.15 $ 2 $ 7 Series A 27,159 27,159 0.73 0.73 20 20 Series B 7,925 7,925 5.68 5.48 45 45 Series C 26,839 26,839 4.79 4.79 128 128 Series D 98,008 98,008 5.51 (1) 5.51 540 535 Series E 18,055 18,055 13.85 13.85 250 250 Series F 18,186 18,186 22.48 22.48 409 476 Series G 21,165 21,165 37.94 37.94 803 803 Series H 9,351 8,316 45.91 45.91 382 382 Total 240,018 238,983 $ 2,579 $ 2,646 (1) The issuance price for Series D redeemable convertible preferred stock was $5.50688, except for shares issued via the conversion of certain of the outstanding convertible promissory notes issued in 2017, for which the conversion price was $4.78778 per share. Forward Contract In Connection with Issuance of Series F Redeemable Convertible Preferred Stock In February 2019, the Company issued a total of 13,736,615 shares of Series F redeemable convertible preferred stock at $22.4751 per share for gross proceeds of $309 million. To accommodate the timing of regulatory approvals required by an existing investor (who did not participate in the initial issuance of Series F redeemable convertible preferred stock), the Company committed to sell 4,449,370 shares of Series F redeemable convertible preferred stock at $22.4751 per share for gross proceeds of $100 million to this investor in a subsequent closing, which ultimately occurred in May 2019. The preferred stock issuance costs were not material. At the date of the initial closing, the Company determined that the commitment to defer the sale of shares of Series F redeemable convertible preferred stock to this investor represented a freestanding instrument that should be classified as a liability and measured at fair value on a recurring basis, with changes in fair value recognized in other expense, net in the consolidated statements of operations. The initial measurement of the liability at its fair value of $1 million was recorded with a corresponding reduction recognized in additional paid-in capital as a deemed dividend distributed to the investor. Immediately prior to the subsequent closing in May 2019, the fair value of the liability was determined to be $68 million, resulting in an expense of $67 million recorded to other (expense) income, net in the consolidated statements of operations which was attributable to the increase in the fair value of Series F redeemable convertible preferred stock. Upon the subsequent closing, the carrying amount of the liability was reclassified to mezzanine equity. The fair value of the liability (valued as a forward contract) at issuance and as of subsequent closing was determined with the following assumptions: As of As of Current forward price per share $ 22.48 $ 37.76 Contractual forward price per share $ 22.48 $ 22.48 Risk-free rate 2.46 % 2.41 % Expected years until subsequent closing 0.23 — Present value of contractual forward price per share $ 22.35 $ 22.48 Value of the forward contract per share $ 0.13 $ 15.28 Number of preferred shares issued in the subsequent closing 4,449,370 4,449,370 Fair value of forward contract liability (in millions) $ 1 $ 68 As of December 31, 2020 and 2021, there was no preferred stock issued and outstanding.

Equity [Abstract]
Common Stock	Common Stock Common Stock Reserved for Future Issuance The following table summarizes the Company’s shares of common stock reserved for future issuance on an as-converted basis (in thousands): December 31, 2020 December 31, 2021 Stock options issued and outstanding under the 2014 Plan 33,802 19,115 RSUs outstanding under the 2014 and 2020 Plan 34,939 27,556 Remaining shares available for future issuance 32,210 42,196 Shares available for issuance under the 2020 Employee Stock Purchase Plan 6,499 6,499 Total 107,450 95,366 2014 Equity Incentive Plan In March 2014, the Company adopted the 2014 Stock Option Plan, as amended ("2014 Plan"), which provided for the granting of stock options to employees, consultants, and advisors of the Company. Options granted under the 2014 Plan are either incentive stock options or nonqualified stock options. Options under the 2014 Plan were granted for a term of up to ten years (or five years if the option was an incentive stock option granted to a greater than 10% stockholder) and at prices no less than 100% of the estimated fair value of the shares on the date of grant as determined by the Company’s board of directors; provided, however, that the exercise price of an incentive stock option granted to a greater than 10% stockholder could not be less than 110% of the estimated fair value of the shares on the date of grant. Options granted generally vest over four years. The 2014 Plan allowed for the early exercise of options. Under the terms of the 2014 Plan, option holders, upon early exercise, were required to sign a restricted stock purchase agreement that gave the Company the right to repurchase any unvested shares, at the original exercise price, in the event the grantees’ employment terminated for any reason. The repurchase right lapses over time as the shares vest at the same rate as the original option vesting schedule. Stock-based awards forfeited, cancelled, or repurchased generally were returned to the pool of shares of common stock available for issuance. In connection with the IPO, the 2014 Plan was terminated effective immediately prior to the effectiveness of the 2020 Equity Incentive Plan ("2020 Plan") and the Company ceased granting any additional awards under the 2014 Plan. All outstanding awards under the 2014 Plan at the time of the termination of the 2014 Plan remain subject to the terms of the 2014 Plan, and any shares underlying stock options that expire or terminate or are forfeited or repurchased by the Company under the 2014 Plan were automatically transferred to the 2020 Plan. 2020 Equity Incentive Plan In November 2020, the Company's board of directors adopted, and the Company's stockholders approved, the 2020 Plan, which became effective one business day prior to the effective date of the IPO Registration Statement. The 2020 Plan provides for the granting of incentive stock options, nonstatutory stock options, restricted stock, RSUs, stock appreciation rights, performance units, and performance shares for the Company's Class A common stock to the Company's employees, directors, and consultants. Stock-based awards under the 2020 Plan that expire or are forfeited, canceled, or repurchased generally are returned to the pool of shares of Class A common stock available for issuance under the 2020 Plan. In addition, the number of shares of the Company's Class A common stock reserved for issuance under the 2020 Plan will automatically increase on January 1 of each calendar year, starting on January 1, 2021 in an amount equal to the least of (i) 32,493,000 shares, (ii) five percent (5%) of the total number of all classes of common stock outstanding on December 31 of the fiscal year before the date of each automatic increase, or (iii) such other number of shares determined by the Company's board of directors prior to the applicable January 1. The exercise price of the options granted under the 2020 Plan will at least be equal to the fair market value of the Company's Class A common stock on the date of grant. The options may be granted for a term of up to ten years (or five years if the option is an incentive stock option granted to a greater than 10% stockholder) and at prices no less than 100% of the fair market value of the shares on the date of grant, provided, however, that the exercise price of an incentive stock option granted to a greater than 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant. Options granted under the 2020 Plan generally vest over four years. RSUs Prior to November 2020 , the Company granted RSUs that vest only upon the satisfaction of both service-based and liquidity event-related performance vesting conditions. The service-based vesting condition for these awards generally is satisfied over four years. The liquidity event-related performance vesting condition was satisfied upon the effectiveness of the IPO Registration Statement. The liquidity event-related performance vesting condition was achieved upon the effectiveness of the Company’s IPO, resulting in the Company recording cumulative stock-based compensation expense of $279 million for IPO Vested RSUs. Stock-based compensation related to the remaining service-based period after the liquidity event-related performance vesting condition was satisfied will be recorded over the remaining requisite service period. Since November 2020, with the exception of the CEO Performance Award discussed below, the Company granted RSUs that vest only upon the satisfaction of a service-based vesting condition which is generally four years. CEO Performance Award In November 2020, the Company’s board of directors approved the grant of 10,379,000 RSUs to the CEO (the “CEO Performance Award”). The CEO Performance Award vests upon the satisfaction of a service condition and achievement of certain stock price goals. The CEO Performance Award is excluded from Class A common stock issued and outstanding until the satisfaction of these vesting conditions. The CEO Performance Award also provides the holder with certain stockholder rights, such as the right to vote the shares with the other holders of Class A common stock and a right to cumulative declared dividends. However, the CEO Performance Award is not considered a participating security for purposes of calculating net loss per share attributable to common stockholders as the right to the cumulative declared dividends is forfeitable if the service condition is not met. The CEO Performance Award is eligible to vest beginning on the first trading day 18 months following the day Company’s IPO date, and expiring seven years after the IPO date. The CEO Performance Award comprises nine tranches that are eligible to vest based on the achievement of stock price goals, ranging from $187.60 to $501.00 per share, each of which are referred to as a Company Stock Price Target, measured over a consecutive 180-day trading period during the performance period as set forth below. This measurement period was designed to reward the CEO only if the Company achieved sustained growth in the stock price. Company Stock Number of RSUs 1 $187.60 518,950 2 $226.80 518,950 3 $265.80 1,037,900 4 $305.00 1,037,900 5 $344.00 1,037,900 6 $383.00 1,556,850 7 $422.20 1,556,850 8 $461.20 1,556,850 9 $501.00 1,556,850 The Company calculated the grant date fair value of the CEO Performance Award based on multiple stock price paths developed through the use of a Monte Carlo simulation model. A Monte Carlo simulation model also calculates a derived service period for each of the nine vesting tranches, which is the measure of the expected time to achieve each Company Stock Price Target. A Monte Carlo simulation model requires the use of various assumptions, including the underlying stock price, volatility, and the risk-free interest rate as of the valuation date, corresponding to the length of time remaining in the performance period, and expected dividend yield. The weighted-average grant date fair value of the CEO Performance Award was $39.8275 per share. The Company will recognize total stock-based compensation expense of $413 million over the derived service period of each tranche, which is between 2.53 to 4.42 years, using the accelerated attribution method as long as the CEO satisfies the service-based vesting condition. If the Company Stock Price Targets are met sooner than the derived service period, the Company will adjust its stock-based compensation to reflect the cumulative expense associated with the vested awards. Provided that Tony Xu continues to be the Company's CEO, the Company will recognize stock-based compensation expense over the requisite service period, regardless of whether the Company Stock Price Targets are achieved. The Company recorded $12 million and $112 million of stock-based compensation expense related to the CEO Performance Award during the years ended December 31, 2020 and 2021, respectively. As of December 31, 2021, unrecognized stock-based compensation expense related to the CEO Performance Award was $289 million.

As of December 31, 2021, there was $1.6 billion of unrecognized stock-based compensation expense related to unvested RSUs, excluding the unrecognized stock-based compensation expense associated with the CEO Performance Award. The Company expects to recognize this expense over the remaining weighted-average period of 2.61 years. 2020 Employee Stock Purchase Plan The Company's board of directors adopted, and the Company's stockholders approved, the 2020 Employee Stock Purchase Plan ("the ESPP"), which became effective on the business day immediately prior to the effectiveness of the IPO. A total of 6,498,600 shares of Class A common stock were initially reserved for sale under the ESPP. The number of shares of Class A common stock available for issuance under the ESPP will be increased on the first day of each fiscal year beginning with the fiscal year following the fiscal year in which the first enrollment date (if any) occurs equal to the least of (i) 6,498,600 shares of Class A common stock, (ii) one and one-half percent (1.5%) of the outstanding shares of all classes of common stock on the last day of the immediately preceding fiscal year, or (iii) an amount determined by the administrator of the ESPP.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes U.S. and foreign components of consolidated loss before income taxes was as follows (in millions): Year Ended December 31, 2019 2020 2021 United States $ (666) $ (463) $ (461) Foreign — 5 (2) Loss before income taxes $ (666) $ (458) $ (463) The Company’s provision for income taxes for the years ended December 31, 2019, 2020, and 2021 was $1 million, $3 million, and $5 million, respectively. The provision for income taxes primarily consisted of franchise tax and U.S. federal and state income tax, as well as international taxes from foreign operations. The reconciliation of the statutory federal income tax rate to the Company’s effective tax rate was as follows: Year Ended December 31, 2019 2020 2021 Federal tax (benefit) at statutory rate 21 % 21 % 21 % State tax (benefit) at statutory rate, net of federal benefit 4 3 4 Change in valuation allowance (23) (21) (225) Stock-based compensation — (2) 155 Research and development credits 1 3 58 Change in fair value of forward contract liability (3) — — Non-deductible expenses — (3) (1) Non-deductible interest expenses — (2) (1) Unrecognized tax benefits — — (12) Provision for income taxes — % (1) % (1) % No deferred tax liabilities for foreign withholding taxes have been recorded relating to the earnings of the Company’s foreign subsidiaries since all such earnings are intended to be indefinitely reinvested. The significant components of the Company’s deferred tax assets and liabilities were as follows (in millions): December 31, 2020 2021 Deferred tax assets Accruals and reserves $ 95 $ 104 Stock-based compensation 72 36 Tax credits carryforward 23 237 Operating leases 64 101 Net operating losses carryforward 180 1,050 Total gross deferred tax assets 434 1,528 Less: Valuation allowance (357) (1,398) Total deferred tax assets net of valuation allowance 77 130 Deferred tax liabilities Property and equipment and intangible assets (19) (36) ROU assets (51) (83) Deferred contract costs (10) (15) Total gross deferred tax liabilities (80) (134) Net deferred tax liabilities $ (3) $ (4) The Company accounts for deferred taxes under ASC 740, Income Taxes, which requires a reduction of the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. Accordingly, the need to establish valuation allowances for deferred tax assets is assessed periodically based on the ASC 740 more-likely-than-not realization threshold criterion. This assessment considers matters such as future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. The evaluation of the recoverability of the deferred tax assets requires that the Company weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax assets will not be realized. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. Due to the lack of U.S. earnings history, the U.S. federal and state deferred tax assets have been fully offset by a valuation allowance. Overall, the valuation allowance increased by $154 million, $97 million and $1,041 million in the years ended December 31, 2019, 2020 and 2021, respectively. As of December 31, 2021, the Company had accumulated federal and state net operating loss carryforwards of $4,125 million and $3,265 million, respectively. Of the $4,125 million of federal net operating losses, $4,042 million is carried forward indefinitely but is limited to 80% of taxable income. The remaining federal and state net operating loss carryforwards will begin to expire in 2036 and 2024, respectively. The Company also had $209 million of federal and $114 million of California research and development tax credit carryforwards as of December 31, 2021. The federal research and development tax credits expire in varying amounts starting in 2033. The California research credits do not expire and may be carried forward indefinitely. The Company’s ability to utilize the net operating loss and tax credit carryforwards in the future may be limited in the event of past or future ownership changes as defined in Section 382 of the Internal Revenue Code of 1986, as amended, and similar state tax law. Based on the most recent analysis, the Company does not anticipate a current limitation on the tax attributes. Unrecognized Tax Benefits Included in the balance of unrecognized tax benefits as of December 31, 2020 and 2021 were $7 million and $69 million, respectively, of tax benefits, that, if recognized, majority would result in adjustments to the valuation allowance. The Company does not anticipate that the amount of unrecognized tax benefits relating to tax positions existing at December 31, 2021 will significantly increase or decrease within the next 12 months. A reconciliation of the beginning and ending balance of gross unrecognized tax benefits is included in the table below (in millions): Year Ended December 31, 2019 2020 2021 Unrecognized tax benefits at beginning of year $ 3 $ 7 $ 7 Increases related to current year tax positions 4 3 62 Decreases related to prior year tax positions — (3) — Unrecognized tax benefits at end of year $ 7 $ 7 $ 69 The Company’s policy is to recognize accrued interest and penalties related to unrecognized tax benefits within provision for income taxes, which were immaterial for the periods presented. The Company files U.S. federal and state income tax returns in the United States federal jurisdiction as well as foreign jurisdictions. The Company’s income tax returns generally remain subject to examination by United States federal and state and foreign tax authorities.

Net Loss per Share Attributable

Net Loss per Share Attributable to Common Stockholders	12 Months Ended
	Dec. 31, 2021
Earnings Per Share [Abstract]
Net Loss per Share Attributable to Common Stockholders	Net Loss per Share Attributable to Common Stockholders The Company computes net loss per share using the two-class method required for multiple classes of common stock and participating securities. The rights, including the liquidation and dividend rights, of the Class A common stock and Class B common stock are identical, other than voting rights. Accordingly, the Class A common stock and Class B common stock share equally in the Company’s net losses. Before the IPO, the Company’s outstanding securities also included convertible preferred stock. The holders of redeemable convertible preferred stock did not have a contractual obligation to share in the Company’s losses, and as a result, net losses were not allocated to these securities. The following table sets forth the calculation of basic and diluted net loss per share attributable to common stockholders during the periods presented. The shares issued in the IPO and the shares of Class A common stock issued upon conversion of the outstanding shares of redeemable convertible preferred stock in the IPO, as well as vested RSUs that have not been settled are included in the table below weighted for the period outstanding in the years ended December 31, 2020 and 2021 (in millions, except share amounts which are reflected in thousands, and per share data): Year Ended December 31, 2019 2020 2021 Common Class A Class B Class A Class B Net loss $ (667) $ (446) $ (15) $ (424) $ (44) Less: Deemed dividend to preferred stockholders (1) — — — — Net loss attributable to common stockholders $ (668) $ (446) $ (15) $ (424) $ (44) Weighted-average number of shares outstanding used to compute net loss per share attributable to common stockholders, basic and diluted 43,252 60,422 1,968 305,500 31,347 Net loss per share attributable to common stockholders, basic and diluted $ (15.44) $ (7.39) $ (7.39) $ (1.39) $ (1.39) The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share because including them would have had an anti-dilutive effect (in thousands): Year Ended December 31, 2019 2020 2021 Redeemable convertible preferred stock (on an as-converted basis) 230,953 — — Stock options to purchase common stock 36,247 33,802 19,115 Unvested restricted stock units (1) 15,924 17,987 17,139 Convertible promissory notes — 2,595 — Total 283,124 54,384 36,254 (1) The CEO Performance Award is excluded from the above table because the Company Stock Price Target had not been met as of December 31, 2020 and 2021.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany transactions have been eliminated in consolidation.
Segments	SegmentsOperating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one reportable segment.
Use of Estimates	Use of EstimatesThe preparation of consolidated financial statements in accordance with GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the period presented. Estimates include, but are not limited to, revenue recognition, allowances for credit losses, gift card breakage, estimated useful lives of property and equipment, capitalized software and website development costs, intangible assets, stock-based compensation, valuation of investments and other financial instruments, valuation of acquired intangible assets and goodwill, the incremental borrowing rate applied in lease accounting, insurance reserves, loss contingencies, and income and indirect taxes. Actual results could differ from these estimates.
Business Combinations	Business Combinations The Company accounts for business combinations using the acquisition method of accounting, which requires, among other things, allocation of the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed at their estimated fair values on the acquisition date. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to the valuation of intangible assets. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, the Company may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill if new information is obtained related to facts and circumstances that existed as of the acquisition date. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are reflected in the consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred.
Cash and Cash Equivalents and Restricted Cash	Cash, Cash Equivalents, and Restricted CashCash includes demand deposits with banks or financial institutions as well as cash in transit from payment processors. Cash equivalents include short-term, highly liquid investments with original maturities of three months or less and their carrying values approximate fair value due to their short-term maturities. Restricted cash consists of collateral provided for letters of credit established primarily for real estate leases and insurance policies.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents, and Restricted CashCash includes demand deposits with banks or financial institutions as well as cash in transit from payment processors. Cash equivalents include short-term, highly liquid investments with original maturities of three months or less and their carrying values approximate fair value due to their short-term maturities. Restricted cash consists of collateral provided for letters of credit established primarily for real estate leases and insurance policies.
Marketable Securities	Marketable Securities Marketable securities primarily consist of commercial paper, U.S. government agency securities, U.S. Treasury securities, and corporate bonds. The Company invests in a diversified portfolio of marketable securities and limits the concentration of its investment in any particular security. Securities with maturities greater than three months, but less than one year, are included in current assets and securities with maturities greater than one year are included in non-current assets on the consolidated balance sheets. All marketable securities are classified as available-for-sale and reported at fair value. If the estimated fair value of an available-for-sale debt security is below its amortized cost basis, then the Company evaluates the security for impairment. The Company considers its intent to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized basis. If either of these criteria are met, the debt security’s amortized cost basis is written down to fair value through other income (expense), net in the consolidated statements of operations. If neither of these criteria are met, the Company evaluates whether unrealized losses have resulted from a credit loss or other factors. The factors considered in determining whether a credit loss exists can include the extent to which fair value is less than the amortized cost basis, changes to the rating of the security by a rating agency, any adverse conditions specifically related to the security, as well as other factors. An impairment relating to credit losses is recorded through an allowance for credit losses reported in other income (expense), net in the consolidated statements of operations. The allowance is limited by the amount that the fair value of the debt security is below its amortized cost basis. When a credit loss exists, the Company compares the present value of cash flows expected to be collected from the debt security with the amortized cost basis of the security to determine what allowance amount, if any, should be recorded. As of December 31, 2020 and 2021, no allowance of credit losses related to marketable securities was recorded. Unrealized losses not resulting from credit losses are recorded through accumulated other comprehensive income (loss).
Funds Held at Payment Processors	Funds Held at Payment Processors Funds held at payment processors represent cash due from the Company’s payment processors for transactions with merchants and consumers, as well as funds transferred to payment processors for Dasher payout.
Accounts Receivable, Net and Allowance for Credit Losses	Accounts Receivable, Net and Allowance for Credit Losses Accounts receivable, net primarily represents receivables from merchants that were generated through the Company’s Drive offering. The Company maintains an allowance for credit losses, which is based on the Company’s assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for credit losses on a collective basis by considering the age of each outstanding invoice, each customer’s expected ability to pay and collection history, current market conditions, and reasonable and supportable forecasts of future economic conditions to determine whether the allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for credit losses when identified.
Property and Equipment, Net	Property and Equipment, Net Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. The useful lives are as follows: Estimated Useful Life Equipment for merchants 2 years Computer equipment and software 2 years Office equipment 5 years Capitalized software and website development costs 2 years Leasehold improvements Shorter of estimated useful life or lease term
Goodwill and Intangible Assets	Intangible Assets, Net Intangible assets are recorded at fair value as of the date of acquisition and amortized on a straight-line basis over their estimated useful lives. The Company reviews identifiable amortizable intangible assets for impairment under the long-lived asset model described under “Impairment of Long-Lived Assets” below. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized, but is tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s impairment tests are based on a single operating segment and reporting unit structure. If the carrying value of the reporting unit exceeds its fair value, an impairment charge is recognized for the excess of the carrying value of the reporting unit over its fair value. The Company conducted its annual goodwill impairment test during the fourth quarter of 2021 and determined that the fair value of the reporting unit significantly exceeded its carrying value. No impairment charge was recorded in any of the periods presented in the accompanying consolidated financial statements. Capitalized Software and Website Development Costs The Company incurred costs relating to the development of the Company’s technology platform, which includes Dasher and merchant tools, mobile apps, and website and content development. Software development costs related to software acquired, developed, or modified solely to meet the Company’s internal requirements, with no substantive plans to market such software at the time of development, are capitalized during the application development stage of the project. Costs incurred during the preliminary planning and evaluation stage of the project and during the post implementation operational stage are expensed as incurred. Costs to develop the Company’s technology platform are capitalized when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Costs incurred for enhancements that are expected to result in additional functionality are capitalized and expensed over the estimated useful life of the upgrades on a per project basis.
Non-Marketable Equity Securities	Non-Marketable Equity Securities Non-marketable equity securities which the Company does not have a controlling financial interest in and does not exercise significant influence over the investee are recorded at cost and adjusted for observable transactions for same or similar investments of the same issuer (referred to as the measurement alternative) or impairment. The carrying value is not adjusted for the Company’s non-marketable equity securities if there are no observable price changes in a same or similar security from the same issuer or if there are no identified events or changes in circumstances that may indicate impairment. In 2021, the Company made investments in non-marketable equity securities of $409 million in cash for preferred shares of private companies including an investment of $395 million in cash for preferred shares of a grocery delivery platform company. All those investments were accounted for using the measurement alternative. There are no adjustments or impairment associated with the Company’s non-marketable equity securities during 2021. The Company does not have any realized or unrealized gains or losses on non-marketable equity securities as of and for the years ended December 31, 2020 and 2021.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company evaluates its long-lived assets or asset groups for indicators of possible impairment by comparison of the carrying amount to future net undiscounted cash flows expected to be generated by such asset or asset group when events or changes in circumstances indicate the carrying amount of an asset or asset group may not be recoverable. Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset or asset group over the asset’s or asset group’s fair value generally determined by estimates of future discounted cash flows.
Insurance Reserves	Insurance ReservesThe Company utilizes third-party insurance which include retained insurance deductibles to insure costs including auto liability related to both bodily injury and physical damage, and uninsured and underinsured motorists up to a certain dollar retention limit. The recorded insurance reserves reflect the estimated cost for claims incurred but not paid and claims that have been incurred but not yet reported. The estimate of the Company’s ultimate deductible obligation utilizes actuarial techniques applied to historical claim and loss experience. Given our limited operational history, the Company utilizes assumptions based on actuarial judgments with consideration toward relevant industry claim and loss development factors, which includes the development time frame and settlement patterns, and expected loss rates. Reserves are periodically reviewed and adjusted as necessary as experience develops or new information becomes known. However, ultimate results may differ from the Company’s estimates, which could result in losses over the Company’s reserved amounts.
Loss Contingencies	Loss Contingencies The Company is involved in various lawsuits, claims, investigations, and proceedings that arise in connection with its business. Certain of these matters include speculative claims for substantial or indeterminate amounts of damages. The Company records a liability in accrued expenses and other current liabilities on the consolidated balance sheets when the Company believes that it is both probable that a loss has been incurred and the amount or range can be reasonably estimated. The Company discloses material contingencies when it believes that a loss is not probable but reasonably possible. Significant judgment is required to determine both probability and the estimated amount. The Company reviews these provisions on a quarterly basis and adjusts these provisions accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information.
Sales and Indirect Taxes	Sales and Indirect Taxes The Company records sales and indirect tax liabilities when they become probable and the amount can be reasonably estimated. Sales and indirect tax liabilities are included in accrued expenses and other current liabilities on the consolidated balance sheets.
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Income (Loss) Accumulated other comprehensive income (loss) consists of foreign currency translation adjustments and unrealized gains and losses on available-for-sale marketable securities. The financial statements of the Company’s foreign subsidiaries are translated from their functional currency, which is typically the local currency, into U.S. dollars. Assets and liabilities are translated at period end rates of exchange, and revenue and expenses are translated using average monthly exchange rates. The resulting gain or loss is included in accumulated other comprehensive income (loss) on the consolidated balance sheets. Available-for-sale securities are reported at fair value, with unrealized gains and losses included as a separate component of stockholders’ equity within accumulated other comprehensive income (loss).
Stock-Based Compensation	Stock-Based Compensation The fair value of RSUs is estimated based on the fair value of the Company’s common stock on the date of grant. Prior to November 2020, RSUs granted by the Company vest upon the satisfaction of both a service-based vesting condition, which is typically four years, and a liquidity event-related performance vesting condition. The liquidity event-related performance vesting condition was achieved upon the consummation of the Company's IPO, and the Company recorded a cumulative stock-based compensation expense of $279 million as of the IPO date for those RSUs for which the service-based vesting condition has been satisfied. Stock-based compensation related to the remaining service-based period after the liquidity event-related performance vesting condition was satisfied will be recorded over the remaining requisite service period using the accelerated attribution method. Since November 2020, with the exception of the CEO Performance Award (as discussed further in Note 12), the Company only granted RSUs that vest upon the satisfaction of a service-based vesting condition and the compensation expense for these RSUs is recognized on a straight-line basis over the requisite service period. For the CEO Performance Award (as defined below) that includes a market condition, the fair value of the award was determined using a Monte Carlo simulation model. The associated stock-based compensation is recorded over the derived service period, using the accelerated attribution method. If the stock price goals are met sooner than the derived service period, the Company will adjust the stock-based compensation expense to reflect the cumulative expense associated with the vested award. Provided that Tony Xu continues to be the Chief Executive Officer of the Company, stock-based compensation expense is recognized over the requisite service period, regardless of whether the stock price goals are achieved. Prior to the IPO, the fair value of the shares of common stock underlying the stock options and RSUs has historically been determined by the Company’s board of directors as there is no public market for the underlying common stock. The Company’s board of directors determined the fair value of the Company’s common stock by considering a number of objective and subjective factors including: contemporaneous third-party valuations of its common stock, the valuation of comparable companies, sales of the Company’s common and redeemable convertible preferred stock to outside investors in arms-length transactions (including the IPO), the Company’s operating and financial performance, the lack of marketability, and the general and industry specific economic outlook, amongst other factors. After the completion of the IPO, the fair value of the Company's Class A common stock is determined based on the New York Stock Exchange ("NYSE") closing price on the date of grant.
Provision for Income Taxes	Provision for Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred income tax assets and liabilities are recorded based on the estimated future tax effects of differences between the financial statement and income tax basis of existing assets and liabilities. These differences are measured using the enacted statutory tax rates that are expected to apply to taxable income for the years in which differences are expected to reverse. The Company recognizes the effect on deferred income taxes of a change in tax rates in the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets to the net amount that it believes is more-likely-than-not to be realized. Management considers all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income, and ongoing tax planning strategies in assessing the need for a valuation allowance. The Company operates in various tax jurisdictions and is subject to audit by tax authorities. The Company recognizes the tax benefit of an uncertain tax position only if it is more-likely-than-not that the position is sustainable upon examination by the taxing authority, based on the technical merits. The tax benefit recognized is measured as the largest amount of benefit which is greater than 50% likely to be realized upon settlement with the taxing authority. The Company recognizes interest accrued and penalties related to unrecognized tax benefits in the provision for income taxes.
Fair Value	Fair Value The Company measures certain assets and liabilities at fair value on a recurring basis based on an expected exit price, which represents the amount that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis, whereby inputs used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value: Level 1 Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 Unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. The carrying amounts of certain of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable, and accrued expenses and other current liabilities approximate their fair values due to their short maturities.
Concentration of Credit Risk	Concentration of Credit Risk The Company’s cash, cash equivalents, marketable securities, funds held at payment processors, and accounts receivable are potentially subject to concentration of credit risk. Although the Company deposits its cash with multiple financial institutions, the deposits, at times, may exceed federally insured limits. Management believes that the institutions are financially stable and, accordingly, minimal credit risk exists. The Company limits purchases of debt securities to investment-grade securities. The Company has not experienced any significant credit losses historically. The Company relies on a limited number of third parties to provide payment processing services (“payment processors”) including collecting amounts due from end-users and processing Dasher payouts. Payment processors are financial institutions or credit card companies that the Company believes are of high credit quality. The Company retains the risk of collecting such amounts from the payment processors, which are included in funds held at payment processors for the unsettled portion at each period end. The portion of the payments to be remitted to Dashers and merchants is included in accrued expenses and other current liabilities. Although the Company pre-authorizes forms of payment to mitigate its exposure, the Company absorbs all credit card losses.
Revenue Recognition	Revenue Recognition The Company recognizes revenue in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with its Customers. The Company generates a substantial majority of its revenue from orders completed through the Marketplace and the related commissions charged to partner merchants and fees charged to consumers. A partner merchant represents a merchant that has entered into a contractual agreement with the Company. Revenue from the Marketplace is recognized at the point in time when the consumer obtains control of the merchant’s products. The Company also generates revenue from membership fees paid by consumers for DashPass, which is recognized as part of the Marketplace. Revenue generated from the Company’s DashPass memberships is recognized on a ratable basis over the contractual period, which is generally one month to one year depending on the type of membership purchased by the consumer. In addition, the Company also generates revenue from its Drive offering by collecting per-order fees from merchants that use its local logistics platform to arrange for delivery services that fulfill demand generated through their own channels. Revenue from Drive is recognized at the point in time when the consumer obtains control of the merchant’s products. When determining the appropriate accounting for the fees collected in exchange for the use of the Company’s local logistics platform, the Company considered its contractual arrangements with the parties involved as well as its customary business practices. Under the Company’s agreements with partner merchants, the Company agrees to a commission to be earned as a percentage of the total dollar value of goods ordered. When a consumer signs up to use the Company’s local logistics platform, the consumer agrees to be charged certain fees, at the time an order is placed, in exchange for use of the platform. The Company has concluded that a contract exists between the Company and a partner merchant when the partner merchant accepts each consumer’s order, and a contract exists between the Company and a consumer when the consumer places the order and requests delivery services. The duration of a contract is typically equal to the time between when the order is placed and a Dasher picks up the food from the merchant. Contracts including variable consideration with partner merchants were not material for the periods presented. The Company’s local logistics platform facilitates orders between consumers and partner merchants. Separately, the Company’s platform arranges for consumers to obtain delivery service from Dashers. The Company has determined that the order facilitation service and delivery facilitation service are distinct performance obligations and has therefore considered whether it is a principal or agent separately for each of these items. The order facilitation service and the delivery facilitation service are distinct given that the consumer can benefit from each item separately. Further, the order facilitation service and delivery facilitation service are separately identifiable as the nature of the promises are to transfer the order facilitation service and delivery facilitation service individually, rather than as a combined item. Principal vs. Agent Considerations Judgment is required in determining whether the Company is the principal or the agent in transactions with partner merchants, consumers, and Dashers. As it relates to the accounting for order facilitation services and delivery facilitation services, the Company evaluated whether to present revenue on a gross versus net basis based on whether it controls each specified good or service before it is provided to the consumer in Marketplace transactions. With respect to order facilitation services, the Company has determined it is an agent for partner merchants in facilitating the sale of products to the consumer through the Marketplace. The consumer accesses the Company’s local logistics platform to identify merchants and places an order for merchants’ products. These orders are picked up from partner merchants and delivered to consumers by Dashers. The Company does not control the products prior to them being transferred to the consumer as it neither has the ability to redirect the products to another consumer nor does it obtain any economic benefit from the products. With respect to the vast majority of its delivery facilitation services, the Company has determined it is acting as an agent for the consumer in facilitating the delivery of products by connecting consumers with Dashers. As the Company’s role with the delivery facilitation service is only to arrange for a delivery opportunity to be offered to prospective Dashers, it does not control how the delivery service is ultimately provided to the consumer. In the vast majority of its transactions with end-users, the Company is an agent in facilitating the sale of products and delivery services, thus the Company reports revenue on a net basis, reflecting amounts collected from consumers, less amounts remitted to merchants and Dashers. Dasher payout represents the amounts paid to Dashers for deliveries, including incentives and tips, except for certain referral bonuses. From time to time, Dashers may request an earlier payment settlement in exchange for a reduction in Dasher payout. The amounts payable to merchants and Dashers are included in accrued expenses and other current liabilities on the consolidated balance sheets as payments are typically settled on a weekly basis. The Company recognizes revenue from both partner merchants and consumers for each successfully completed transaction. The Company satisfies its performance obligations to a partner merchant when there is a successful sale of the merchant’s products and meets its performance obligation to a consumer once the Dasher has picked up the products from the merchant for delivery to the consumer. The Company also provides value-add services to merchants. These services are generally considered separate performance obligations and revenue is recognized over the period in which services are provided. Revenue generated from such services is not material in all periods presented. Gift Cards The Company sells gift cards to consumers that can be redeemed through the Marketplace. Those gift cards have no expiration date and administrative fees are not charged on unused gift cards. In prior periods, with limited history as to consumers' redemption patterns, proceeds from the sale of gift cards were fully deferred and recorded as contract liabilities until consumers used the card to place orders on its platform. When gift cards are redeemed, revenue is recognized on a net basis as the difference between the amounts collected from consumers less amounts remitted to merchants and Dashers. During the year ended December 31, 2021, the Company concluded that it had developed sufficient historical evidence regarding the pattern of consumer redemptions of gift cards to have the ability to estimate the portion of outstanding gift cards that will never be redeemed (“breakage”) and for which there is no legal obligation to remit the value of the unredeemed gift cards to the relevant jurisdiction as unclaimed or abandoned property. The Company recognizes the breakage amounts as revenue, proportionate to the pattern of revenue recognition for the gift card redemptions. As a result of this change in estimate, the Company recorded $48 million of gift card breakage revenue during the year ended December 31, 2021. Estimating future breakage rates requires judgment based on current and historical patterns of redemption, and the actual breakage rates may vary from the estimate. Refunds and Credits From time to time the Company issues credits or refunds to merchants and consumers to ameliorate issues that may arise with orders. The Company accounts for such refunds as variable consideration and therefore records the amount of each refund or credit issued as a reduction of revenue. Incentive Programs The Company offers incentives to attract consumers and Dashers to use its local logistics platform. Consumers typically receive credits or discounted delivery fees while Dashers typically receive cash incentives. Each of the incentives are described below: Consumer Promotions The Company uses promotions in tandem with sales and marketing spend to attract new consumers to its platform. Promotions offered to consumers are primarily recorded as a reduction of revenue and include the following: New consumer incentives: The Company records discounts and incentives provided to new consumers as a promotion and reduces revenue on the date that the corresponding revenue transaction is recorded. Consumer referrals: The Company offers referral credits to its existing consumers for referrals of new consumers. These referral credits are paid in exchange for a distinct marketing service and therefore the portion of these credits that is equal to or less than the fair value of acquiring a new consumer are accounted for as a consumer acquisition cost. These new consumer acquisition costs are expensed as incurred and reflected as sales and marketing expenses in the Company’s consolidated statements of operations. The portion of these credits in excess of the fair value of acquiring a new consumer is accounted for as a reduction of revenue. Existing consumer incentives: On occasion, the Company offers promotional discounts to existing consumers. The Company records incentives provided to existing consumers as a promotion and reduces revenue on the date that the corresponding revenue transaction is recorded. Dasher Incentives and Referrals The Company offers various incentives to Dashers, which are primarily recorded within Dasher payout and reduce revenue. These are offered in various forms and include: Peak pay : The Company makes additional payments to Dashers to incentivize them to accept delivery opportunities during peak demand time. Dasher referrals : The Company offers referral bonuses to referring Dashers, as well as to referred Dashers, once the new Dasher has met certain qualifying conditions. The Company expenses the fair value of payments made to the referring Dashers as incurred in sales and marketing expenses in the consolidated statements of operations, since the marketing of the Company’s platform to acquire new Dashers represents a distinct benefit to the Company. The portion of these referral bonuses in excess of the fair value of payments made to the referring Dashers is accounted for as a reduction of revenue. Payments made to the referred Dashers are recorded within Dasher payout and reduce revenue at the time the corresponding revenue transaction is recorded.
Advertising Expense	Advertising CostsAdvertising costs are expensed when incurred and are included in sales and marketing expenses in the consolidated statements of operations.
Net Loss Per Share Attributable to Common Stockholders	Net Loss Per Share Attributable to Common Stockholders The Company computes net loss per common share following the two-class method required for multiple classes of common stock and participating securities. The Company considers its previously outstanding redeemable convertible preferred stock to be participating securities. The two-class method requires income (loss) available to common stockholders for the period to be allocated between multiple classes of common stock and participating securities based upon their respective rights to receive dividends as if all income (loss) for the period had been distributed. The holders of the Company’s redeemable convertible preferred stock would be entitled to dividends in preference to common stockholders, at specified rates, if declared. Such dividends are not cumulative. Any remaining earnings would be distributed among the holders of redeemable convertible preferred stock and common stock pro rata on an as-converted basis. These holders of the Company’s redeemable convertible preferred stock are not contractually obligated to participate in the Company’s losses. As such, the Company’s net losses were not allocated to these participating securities. The rights, including the liquidation and dividend rights, of the Class A common stock, Class B common stock, and Class C common stock are substantially identical, other than voting rights. Accordingly, the Class A common stock and Class B common stock shared proportionately in the Company’s net losses. No shares of Class C common stock were issued and outstanding as of December 31, 2020 and 2021. Prior to the completion of the IPO, there were no shares of Class B common stock issued and outstanding. Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. The diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the period. For periods in which the Company reports net losses, diluted net loss per common share is the same as basic net loss per common share, because all potentially dilutive securities are anti-dilutive. Vested RSUs that have not been settled have been included in the appropriate common share class used to calculate basic net loss per share.
Deferred Offering Costs	Deferred Offering CostsDeferred offering costs, which consist of direct incremental legal, consulting, accounting, and other fees relating to the anticipated sale of the Company’s common stock in the IPO, were initially capitalized and recorded in other assets on the consolidated balance sheets.
Leases	Leases The Company determines if an arrangement is or contains a lease at inception. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. ROU assets represents the Company's right to use the underlying assets for the lease term and lease liabilities represents the Company's obligation to make lease payment arising from the lease. The Company has elected the practical expedient not to recognize ROU assets and lease liabilities for short-term leases with terms of twelve months or less. Expense related to short-term leases is recognized either straight-line over the lease term or as incurred depending on whether the lease payments are fixed or variable. ROU assets are recognized as the lease liability, adjusted for lease incentives received. Lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The Company’s classes of assets that are leased include real estate leases and equipment leases. Operating leases consist of real estate leases and are included in operating lease ROU assets and operating lease liabilities on the Company’s consolidated balance sheets. Finance leases consist of equipment leases and are included in property and equipment, net on the Company’s consolidated balance sheets. Most of the Company’s leases are operating leases, and activities related to finance leases were not material for the periods presented. The Company’s real estate leases are for an initial period between one The Company subleases certain portions of buildings subject to operating leases. The terms and conditions of the subleases are commensurate with the terms and conditions within the original operating leases. The term of the subleases generally range from four When the discount rate implicit in the lease cannot be readily determined, the Company uses the applicable incremental borrowing rate at lease commencement in order to discount lease payments to present value for purposes of performing lease classification tests and measuring the lease liability. The incremental borrowing rate represents the rate of interest the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Because the Company does not typically borrow on a collateralized basis, it
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted In December 2019, the FASB issued Accounting Standard Update ("ASU") 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes", which eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. For public business entities, this standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company adopted 2019-12 on January 1, 2021. The cumulative effect upon adoption was not material to its consolidated financial statement. Recent 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 ASC Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company is in the process of evaluating the impact of the adoption of the update on its consolidated financial statements.
