Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Description of Business Coupang, Inc. (“Coupang”), together with its wholly-owned subsidiaries (collectively, the “Company,” “we,” “us,” or “our”), is a Delaware corporation, which owns and operates an e-commerce business that currently serves the Korean retail market. Through the Company’s mobile applications and Internet websites, the Company offers products and services that span a wide range of categories, including home goods and décor, apparel and beauty products, fresh food and grocery, sporting goods, electronics, restaurant order and delivery, travel and everyday consumables, which are offered through a fully integrated fulfillment and logistics infrastructure. The Company’s main operations, including procurement, marketing, technology, administrative functions, and fulfillment and logistics infrastructure, are predominantly located in South Korea, with some support services performed in China, Singapore, and the United States. Initial Public Offering On March 15, 2021, the Company completed its initial public offering (“IPO”) in which it issued and sold 100,000,000 shares of its Class A common stock at a price of $35.00 per share. The Company received net proceeds of approximately $3.4 billion from the IPO after deducting underwriting discounts of $69 million and other offering costs. Immediately prior to effectiveness of the Company’s IPO registration statement on Form S-1, Coupang, LLC, a Delaware limited liability company, converted into a Delaware corporation pursuant to a statutory conversion, which changed the Company’s name to Coupang, Inc. (“Corporate Conversion”). As a result of the Corporate Conversion and IPO, the Company’s redeemable convertible preferred units (“preferred units”) and common units (which included common units designated as profits interests (“PIUs”)), in each case, automatically converted into an equal number of shares of Class A or Class B common stock, except with respect to a conversion adjustment to certain PIUs, which reduced the outstanding common units designated as PIUs that were converted into shares of Class A common stock. Also, the Company’s convertible notes were automatically converted into shares of Class A common stock. For additional information related to the Company’s Corporate Conversion and IPO, see Note 10 — "Redeemable Convertible Preferred Units and Stockholders'/Members' Equity (Deficit)" and Note 8 — "Convertible Notes and Derivative Instrument." Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited consolidated financial statements as of that date. The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company’s financial position, results of operations and comprehensive loss, redeemable convertible preferred units and stockholders’/members’ equity (deficit), and cash flows for the periods presented, but are not necessarily indicative of the results of operations to be anticipated for any future annual or interim period. Certain information and note disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes included in the final prospectus dated March 10, 2021, as filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (File No. 333-253030) (“Final Prospectus”). Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates, which include, but are not limited to, equity-based compensation, inventory valuation, income taxes, defined severance benefits, and revenue recognition. Actual results could differ materially from those estimates. We based our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Given the global economic climate and additional or unforeseen effects from the COVID-19 pandemic, these estimates become more challenging, and actual results could differ materially from these estimates. Segment Information The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer. The Company has determined that it operates in one operating segment and one reportable segment. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Equity-based Compensation The Company accounts for equity-based employee compensation arrangements in accordance with U.S. GAAP, which requires compensation expense for the grant-date fair value of equity-based awards to be recognized over the requisite service period. The Company determines the fair value of equity-based awards granted or modified on the grant date or modification date using appropriate valuation techniques. Forfeitures are estimated using historical experience at the time of grant and revised in subsequent periods if actual forfeitures differ from initial estimates. Prior to the IPO, the grant-date fair value of equity-based awards was primarily determined using the estimated fair value of the Company's previously issued common units. Common unit fair value estimates were developed by considering numerous objective and subjective factors that required judgment. Subsequent to the IPO, the Company determines the fair value of its Class A common stock using the market closing price on the grant date. During the first quarter of 2021, the Company changed its policy for recognizing equity-based compensation expense from the graded vesting attribution method of accounting to the straight-line attribution method of accounting for its equity-based compensation arrangements with service only vesting conditions. For additional information, see Note 2 — "Change in Accounting Principle." Restricted Stock Units The Company had previously granted restricted equity units under its 2011 Equity Incentive Plan (“2011 Plan”), which vest upon the satisfaction of both a service-based condition and a performance-based condition. In connection with the Company’s Corporate Conversion, the outstanding awards were converted into restricted stock units (“RSUs”). Following the IPO and Corporate Conversion, the Company has granted RSUs that vest upon the satisfaction of a service-based condition as defined in the Company’s 2021 Equity Incentive Plan (“2021 Plan”). The grant-date fair value of each RSU, net of estimated forfeitures, is recognized as expense over the requisite service period. Stock Options The Company had previously granted unit options under the 2011 Plan, which vest over a service period of generally four years. In connection with the Company’s Corporate Conversion, the outstanding awards were converted into stock options. The grant-date fair value of each stock option award, net of estimated forfeitures, is recognized as expense over the requisite service period. The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing model, which requires the input of subjective assumptions, including the expected stock price volatility over the expected term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate for the expected term of the award, and expected dividends. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected term of the options for each option group. The assumptions used to determine the fair value of the option awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. Profits Interests Prior to the IPO, the Company granted common units designated as PIUs that vested upon the satisfaction of a service-based condition and with respect to certain awards, vesting accelerates upon the occurrence of an IPO. The grant-date fair value of the PIUs, net of estimated forfeitures, were recognized as expense over the requisite service period. Concentration of Credit Risk Cash and cash equivalents, restricted cash and accounts receivable are potentially subject to concentration of credit risk. Cash and cash equivalents, and restricted cash are placed with several financial institutions that management believes are of high credit quality, of which 90% are held at five financial institutions as of March 31, 2021. The Company’s gross accounts receivable include amounts concentrated with four payment processing companies representing 72% of gross accounts receivable at March 31, 2021. Recent Accounting Pronouncements Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes certain exceptions for performing intraperiod allocation, recognize deferred taxes for investments, and calculating income taxes in interim periods. The standard reduces complexity in certain areas, including franchise taxes that are partially based on income and accounting for tax law changes in interim periods. The ASU is effective for public companies for fiscal years beginning after December 15, 2020, with early adoption permitted. We adopted this ASU effective January 1, 2021. The adoption of the ASU did not have a material impact on our condensed consolidated financial statements. Recent Accounting Pronouncements Yet To Be Adopted In August 2020, the FASB issued ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40).” The standard reduces the number of models used to account for convertible instruments, amends diluted earnings per share (“EPS”) calculations for convertible instruments, and amends the requirements for a contract (or embedded derivative) that is potentially settled in an entity's own shares to be classified in equity. The amendments add certain disclosure requirements to increase transparency and decision-usefulness about a convertible instrument's terms and features. Under the amendment, the Company must use the if-converted method for including convertible instruments in diluted EPS as opposed to the treasury stock method. The ASU is effective for public companies for fiscal years beginning after December 15, 2021. Early adoption is allowed under the standard with either a modified retrospective or full retrospective method. The Company is currently evaluating this guidance to determine the impact to our condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” In January 2021, the FASB clarified the scope of this guidance with the issuance of ASU 2021-01, “Reference Rate Reform: Scope.” ASU 2020-04 provides optional expedients and exceptions to account for contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate if certain criteria are met. ASU 2020-04 may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating future impacts that may result from the potential adoption of ASU 2020-04.

Change in Accounting Principle

Accounting Changes and Error Corrections [Abstract]
Change in Accounting Principle	Change in Accounting Principle In the first quarter of 2021, the Company changed its policy for recognizing equity-based compensation expense from the graded vesting attribution method of accounting to the straight-line attribution method of accounting for its equity-based compensation arrangements with service only vesting conditions. The Company believes the straight-line attribution method of accounting for equity-based compensation expense for awards with service only vesting conditions is preferable because it more appropriately reflects how awards are earned over an employee’s service period and is the predominant method used in its industry. Comparative financial statements for prior periods have been adjusted to apply the straight-line attribution method retrospectively. The following table presents the comparative effect of the change in accounting method and its impact on the Company’s condensed consolidated statements of operations (in thousands, except for per share amounts): Three Months Ended March 31, 2020 As Reported As Adjusted Total net revenues $ 2,413,259 $ 2,413,259 Cost of sales 1,982,991 1,982,964 Operating, general and administrative 505,815 503,932 Total operating cost and expenses 2,488,806 2,486,896 Operating loss (75,547) (73,637) Loss before income taxes (107,140) (105,230) Income tax expense 123 123 Net loss (107,263) (105,353) Net loss attributable to Class A and Class B common stockholders $ (142,134) $ (140,224) Net loss attributable to Class A and Class B common stockholders per share, basic and diluted (1) $ (5.82) $ (5.74) Weighted-average number of Class A and Class B common shares outstanding used in computing per share amounts, basic and diluted (1) 24,409 24,409 Comprehensive loss $ (109,513) $ (107,603) _____________ (1) As reported net loss per share reflects the retrospective adjustments from the Corporate Conversion described in Note 14 — "Net Loss per Share." The following table presents the comparative effect of the change in accounting method and its impact on the Company’s condensed consolidated balance sheets (in thousands): As of December 31, 2020 As Reported As Adjusted Stockholders'/members’ equity (deficit) Common units $ 54,950 $ 45,122 Additional paid-in capital 25,036 25,036 Accumulated other comprehensive loss (31,093) (31,093) Accumulated deficit (4,117,755) (4,107,927) Total stockholders'/members’ equity (deficit) $ (4,068,862) $ (4,068,862) There was no net impact to the amounts reported for net cash used in/provided by operating, investing or financing activities in the condensed consolidated statements of cash flows for prior periods as a result of the change in accounting method. However, for the three months ended March 31, 2020, net loss and equity-based compensation expense in cash flows from operating activities each decreased $2 million to reflect the change in accounting method. The cumulative effect of the change in accounting method had no net impact on stockholders’/members’ equity (deficit) as of January 1, 2020, the beginning of the earliest year presented in the condensed consolidated financial statements.

Leases [Abstract]
Operating Leases	Leases The Company is obligated under operating leases primarily for vehicles, equipment, warehouses, and facilities that expire over the next eleven years. These leases generally contain renewal options. Because the Company is not reasonably certain to exercise these renewal options, or the renewal options are not solely within the Company’s discretion, the options are not considered in determining the lease term, and the associated potential option payments are excluded from expected minimum lease payments. The Company’s leases generally do not include termination options for either party or restrictive financial or other covenants. The Company’s finance leases as of March 31, 2021 and December 31, 2020 were not material and are included in property and equipment, net, on the Company's condensed consolidated balance sheets. The components of operating lease cost for the three months ended March 31, 2021 and 2020 were as follows (in thousands): 2021 2020 Operating lease cost $ 75,397 $ 33,519 Variable lease cost 625 34 Short-term lease cost 8,357 5,110 Total operating lease cost $ 84,379 $ 38,663 Supplemental disclosure of cash flow information related to leases for the three months ended March 31, 2021 and 2020 were as follows (in thousands): 2021 2020 Cash paid for the amount used to measure the operating lease liabilities $ 58,116 $ 30,524 Operating lease assets obtained in exchange for lease obligations $ 214,745 $ 112,539 Reductions to operating lease ROU assets resulting from remeasurements of lease obligations $ 6,938 $ 4,907 The assumptions used to value leases for the periods presented were as follows: March 31, 2021 December 31, 2020 Operating leases weighted-average remaining lease term 6.5 years 6.2 years Operating leases weighted-average discount rate 6.03 % 5.88 % Amounts disclosed for ROU assets obtained in exchange for lease obligations include amounts added to the carrying amount of ROU assets resulting from lease modifications and reassessments, and new leases. As of March 31, 2021, the Company had entered into operating leases that have not commenced with future minimum lease payments of $429 million, that have not been recognized on the Company's condensed consolidated balance sheets.

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP established a hierarchy framework to classify the fair value based on the observability of significant inputs to the measurement. The levels of the fair value hierarchy are as follows: Level 1: Observable inputs such as quoted prices in an active market for identical assets or liabilities. Level 2: Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs other than the quoted prices that are observable either directly or indirectly for the full term of the assets or liabilities. Level 3: Unobservable inputs in which there is little or no market data and that are significant to the fair value of the assets or liabilities. The following table summarizes the Company's financial assets and financial liabilities that are measured at fair value on a recurring basis (in thousands): March 31, 2021 Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents Money market trust $ 236,021 $ — $ — $ 236,021 Money market funds 35,293 — — 35,293 Restricted cash Time deposit 134,274 — — 134,274 Money market trust 61,823 — — 61,823 Other current assets Time deposit 17,644 — — 17,644 Long-term restricted cash Time deposit 2,301 — — 2,301 Money market account 2,501 — — 2,501 Total financial assets $ 489,857 $ — $ — $ 489,857 December 31, 2020 Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents Money market trust $ 629,393 $ — $ — $ 629,393 Money market funds 35,641 — — 35,641 Restricted cash Time deposit 144,949 — — 144,949 Other current assets Time deposit 18,382 — — 18,382 Long-term restricted cash Time deposit 4,898 — — 4,898 Total financial assets $ 833,263 $ — $ — $ 833,263 Financial liabilities: Derivative instrument $ — $ — $ — $ — Total financial liabilities $ — $ — $ — $ — The following table summarizes information about the significant unobservable inputs used in the fair value measurement of the Company’s derivative instrument (in thousands): December 31, 2020 Fair Value Valuation Technique Unobservable Inputs Input Amount Derivative instrument $ — Valuation of convertible notes with and without the derivative instrument.

In December 2019, the Company entered into a one-year revolving facility agreement, secured by the Company’s inventories. As of March 31, 2021, the $132 million revolving facility was secured by $1.1 billion of the Company’s inventories. Prior to the expiration of the original term of the revolving facility in January 2021, the Company exercised an option that allowed it to extend the maturity of the borrowing facility for an additional 364 days from the expiration date. The revolving facility bears interest at the average of final quotation yield rates for 91-day KRW-denominated bank certificate of deposit (“CD interest rate”) plus 3.25%, and has a commitment fee of 0.75% on the undrawn portion. Under the facility agreement, Coupang Corp., one of the Company’s wholly-owned subsidiaries, is restricted from loaning money to its parent, Coupang, Inc.

(2) The Company entered into various loan agreements with fixed interest rates for general operating purposes. (3) In November 2019, the Company entered into a fixed-rate term loan facility agreement, secured by certain of the Company’s accounts receivable. At March 31, 2021, the Company had $3 million deposited in the trust account for repayment guarantee purposes, which is classified as short-term restricted cash on the condensed consolidated balance sheets. Principal and interest are to be paid on a monthly basis. (4) In March 2017, the Company entered into a term loan facility agreement. As of March 31, 2021, the Company had pledged $344 million of its land, building, inventories, and short-term financial instruments as collateral against any borrowed amounts. Interest accrues at fixed rates on outstanding borrowings under separate tranches within the term loan facility. Additionally, as of March 31, 2021, the Company had deposited $7 million into time deposits, which is classified as short-term restricted cash. Principal is to be paid at maturity and interest is to be paid on a quarterly basis. (5) Borrowings under the new revolving credit facility bear interest, at the Company’s option, at a rate per annum equal to (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 for a one-month interest period plus 1.00% or (ii) an adjusted LIBOR plus a margin equal to 1.00%. During February 2021, the Company entered into a new three-year senior unsecured credit facility (the “new revolving credit facility”) providing for revolving loans in an aggregate principal amount of up to $475 million (which automatically increased to an aggregate principal amount of $950 million based on the Company receiving at least $2.0 billion in net proceeds from its IPO). The new revolving credit facility provides the Company the right to request incremental commitments up to $1.25 billion, subject to customary conditions. During March 2021, the aggregate principal amount of the Company’s new revolving credit facility increased to an aggregate principal amount of $1.0 billion as a result of its IPO. As of March 31, 2021, there was no balance outstanding on the new revolving credit facility. The new revolving credit facility contains customary affirmative and negative covenants, including certain financial covenants. The new revolving credit facility is guaranteed on a senior unsecured basis by all material restricted subsidiaries of the Company, subject to customary exceptions. Borrowings under the new revolving credit facility are not permitted to the extent any amounts are drawn under our existing revolving credit facility. The Company was in compliance with the covenants for each of its borrowings and debt agreements as of March 31, 2021. The Company’s long-term debt is recorded at amortized cost. The fair value is estimated using Level 2 inputs based on the Company’s current interest rate for similar types of borrowing arrangements. The carrying amount of the long-term debt approximates its fair value as of March 31, 2021 and December 31, 2020 due primarily to the interest rates approximating market interest rates. Future principal payments for long-term debt as of March 31, 2021 were as follows (in thousands): Long-term debt Remainder of 2021 $ 52,650 2022 395,199 2023 213 2024 — 2025 — Thereafter — Total $ 448,062

Debt Disclosure [Abstract]
Convertible Notes and Derivative Instrument	Convertible Notes and Derivative Instrument From February 23, 2018 to May 16, 2018, the Company issued convertible notes in an aggregate principal amount of $502 million (total proceeds of $507 million, which included a total net funding premium at issuance), the majority of which were purchased by existing unitholders of the Company’s preferred units, with a maturity equal to the earlier of (a) the fourth anniversary from the first issuance date, (b) the consummation of a liquidity event, or (c) upon an event of default, as defined in the LLC Agreement. In connection with the Company’s IPO in March 2021, the principal balance and the accrued interest on the convertible notes were automatically converted into 171,750,446 shares of the Company’s Class A common stock. The convertible notes had an annual effective interest rate of 16.99%. The Company recorded interest expense for the three months ended March 31, 2021 and 2020 of $20 million and $21 million, respectively, consisting of $15 million and $12 million of contractual interest expense and $5 million and $9 million of debt discount amortization, respectively. The convertible notes contained embedded derivatives that allowed or required the holders of the convertible notes to convert them into a variable number of the Company’s equity securities for a value equal to a significant premium over the then principal and accrued interest balance. These embedded derivatives were bifurcated and accounted for separately as a single, compound derivative instrument. The convertible notes did not convert to common shares based on this embedded feature, rather they converted based on a price calculated by dividing $6.3 billion with the number of common equity securities, on an as-converted and as-exercised basis, outstanding on the closing of the IPO. Following the convertible notes conversion to shares of Class A common stock, the embedded derivatives no longer exist. There was no change in fair value of the derivative instrument during the three months ended March 31, 2021. The change in fair value of the derivative instrument resulted in a loss of $18 million for the three months ended March 31, 2020, which was recognized in the condensed consolidated statements of operations and comprehensive loss within “Other expense, net.”

Legal Matters From time to time, the Company may become party to litigation incidents in the ordinary course of business. The Company assesses the likelihood of any adverse judgments or outcomes with respect to these matters and determines loss contingency assessments on a gross basis after assessing the probability of incurrence of a loss and whether a loss is reasonably estimable. In addition, the Company considers other relevant factors that could impact its ability to reasonably estimate a loss. A determination of the amount of reserves required, if any, for these contingencies is made after analyzing each matter. The Company's reserves may change in the future due to new developments or changes in strategy in handling these matters. 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, consolidated financial position, results of operations, or cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

Pursuant to the Corporate Conversion and IPO: • 1,196,605,432 preferred units and 85,579,584 common units (which include 22,443,220 PIUs), in each case, automatically converted into an equal number of shares of Class A common stock, except with respect to a conversion adjustment which reduced the outstanding common units designated as PIUs by 75,862 common units, and excluding any such preferred units and common units (including any PIUs) held by Mr. Bom Suk Kim; and • 132,859,550 preferred units held by Mr. Kim and 43,143,440 common units (all of which were designated as PIUs) held by Mr. Kim, in each case, converted into an equal number of shares of Class B common stock. On March 15, 2021, the Company completed its IPO, in which it issued and sold 100,000,000 shares of its Class A common stock at a price of $35.00 per share. The Company received net proceeds of approximately $3.4 billion from its IPO after deducting underwriting discounts of $69 million and other offering costs. Also, the owner of our Class B common stock converted 1,200,000 shares of Class B common stock into Class A common stock, which were sold in the IPO. Our certificate of incorporation provides for two classes of common stock, and authorizes shares of undesignated preferred stock, the rights, preferences, and privileges of which may be designated from time to time by our board of directors. Our authorized capital stock consists of 10,000,000,000 shares of Class A common stock, par value $0.0001 per share; 250,000,000 shares of Class B common stock, par value $0.0001 per share; and 2,000,000,000 shares of undesignated preferred stock, par value $0.0001 per share. No preferred stock was issued and outstanding as of March 31, 2021 and December 31, 2020. The shares of Class A common stock and Class B common stock are identical, except with respect to voting, conversion, and transfer rights. Each share of Class A common stock is entitled to one vote. Each share of Class B common stock is entitled to twenty-nine votes. In addition, each share of our Class B common stock will convert automatically into one share of our Class A common stock upon any transfer, whether or not for value, except certain transfers to entities, to the extent the transferor retains sole dispositive power and exclusive voting control with respect to the shares of Class B common stock. Accumulated Other Comprehensive Loss Accumulated other comprehensive loss includes all changes in equity during a period that have yet to be recognized in income. The major components are foreign currency translation adjustments and actuarial gains (losses) on the Company’s defined severance benefits.

Share-based Payment Arrangement [Abstract]
Equity-based Compensation Plans	Equity-based Compensation Plans Our board of directors adopted the 2021 Plan in February 2021, which was approved by our stockholders in February 2021. The 2021 Plan provides for the granting of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards, and other equity-based awards (or the cash equivalent thereof). Initially, the maximum number of shares of the Company’s Class A common stock that may be issued under the 2021 Plan is 215,103,732 shares. In addition, the number of shares of the Company’s Class A common stock reserved for issuance under the 2021 Plan may be increased on January 1 of each calendar year, starting on January 1, 2022 through January 1, 2031, in an amount equal to 5% of the total number of shares of the Company’s capital stock outstanding on the last day of the calendar month before the date of each automatic increase, or a lesser number of shares determined by the Company’s board of directors. Shares subject to stock awards granted under the 2021 Plan that expire or terminate without being exercised in full, or that are paid out in cash rather than in shares, do not reduce the number of shares available for issuance under the 2021 Plan. Additionally, shares become available for future grant under the 2021 Plan if they were issued under stock awards under the 2021 Plan and the Company repurchases them or they are forfeited. RSUs The Company had previously granted restricted equity units under the 2011 Plan, which vest upon the satisfaction of both a service-based condition and a performance-based condition. In connection with the Company’s Corporate Conversion and IPO, the outstanding awards were converted into RSUs. For the RSUs with the performance condition satisfied upon the completion of the Company’s IPO, the Company recorded $41 million in equity-based compensation expense, consisting primarily of a cumulative catch-up adjustment related to such awards based on the full or partial fulfillment of requisite service periods. Unrecognized equity-based compensation expense related to these awards will be recorded over the remaining requisite service period. During the three months ended March 31, 2021, the Company granted 5.3 million RSUs. The weighted-average grant-date fair value of these RSUs was $22.89, which are expected to vest over 2 to 4 years from the vesting start date. As of March 31, 2021, the Company had $173 million of unamortized compensation costs related to all unvested RSU awards. The unamortized compensation costs are expected to be recognized over a weighted-average period of approximately 3.0 years, net of estimated forfeitures. Stock Options The Company had previously granted unit options under the 2011 Plan, which vest upon the satisfaction of a service-based condition. In connection with the Company’s Corporate Conversion and IPO, the outstanding awards were converted into stock options. The Company’s stock options are granted with exercise prices equal to the estimated fair value of the common shares at the date of grant. The stock options expire ten years from the grant date. During the three months ended March 31, 2021, the Company granted 6.6 million options. The weighted-average grant-date fair value of these options was $8.83. Outstanding vested stock options were 9.6 million and 31.2 million as of March 31, 2021 and December 31, 2020, respectively. The total unrecognized compensation expense related to unvested stock options was $80 million, which will be recognized over the weighted-average remaining service period of approximately 2.7 years, net of estimated forfeitures. PIUs Prior to the IPO, the Company granted common units designated as PIUs that vested upon the satisfaction of a service-based condition and with respect to certain awards, vesting accelerates upon the occurrence of an IPO. Holders of vested PIUs had similar rights to those of common unit holders. The PIUs (with the exception of those granted to the Company’s Chief Executive Officer, which convert into an equal number of shares of Class B common stock) convert to shares of Class A common stock at a ratio based on the excess of the per common unit value of the Company at the time of a Corporate Conversion over the per common unit value designated at the grant date of the PIUs (the participation threshold), as specified in the underlying award agreements. All outstanding PIUs automatically converted into 22,367,358 shares of Class A common stock and 43,143,440 shares of Class B common stock at the time of the Corporate Conversion. Furthermore, the accelerated vesting condition of all unvested PIUs were satisfied upon the completion of the Company's IPO and thus, the Company recorded $25 million in equity-based compensation related to the accelerated vesting of PIUs for the three months ended March 31, 2021. Equity-based Compensation Expense Stock options and RSUs are measured at the estimated fair value on the measurement date, which is typically the grant date. In the first quarter of 2021, the Company changed its policy for recognizing equity-based compensation expense from the graded vesting attribution method of accounting to the straight-line attribution method of accounting for its equity-based compensation arrangements with service only vesting conditions. For additional information, see Note 2 — "Change in Accounting Principle," The following table presents the effects of equity-based compensation, as retrospectively adjusted for the change in accounting principle described above, in the condensed consolidated statements of operations and comprehensive loss for three months ended March 31, 2021 and 2020 (in thousands): 2021 2020 Cost of sales $ 1,609 $ 182 Operating, general and administrative 85,357 6,198 Total $ 86,966 $ 6,380

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s tax provision or benefit from income taxes for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment. No income tax benefit was accrued for jurisdictions where the Company anticipates incurring a loss during the full fiscal year as the related deferred tax assets were fully offset by a valuation allowance. The Company’s resulting effective tax rate differs from the applicable statutory rate primarily due to the valuation allowance against its deferred tax assets. The Company is subject to income taxation through certain of its subsidiaries in the United States, China, South Korea and Singapore. Our income tax expense for the three months ended March 31, 2021 and 2020 was $0.0 million and $0.1 million, respectively, primarily attributable to state minimum tax and franchise tax. Significant judgment is required in evaluating the Company’s tax positions and determining its provision for income taxes. The impacts of uncertain tax positions are recognized only after determining a more-likely-than-not probability that the uncertain tax positions will not withstand challenge, if any, from the relevant taxing authorities. The Company did not have any material uncertain tax positions as of March 31, 2021 and 2020.

Earnings Per Share [Abstract]
Net Loss per Share	Net Loss per Share The Company computes net loss per share using the two-class method required for multiple classes of common stock and participating securities. As the liquidation and dividend rights are identical, the undistributed earnings or loss are allocated on a proportionate basis to each class of common stock, and the resulting basic and diluted net loss per share attributable to common stockholders are therefore the same for Class A and Class B common stock on both an individual and a combined basis. Basic net loss per share is computed using the weighted-average number of shares of Class A and Class B common stock outstanding during the period. Diluted net loss per share is computed using the weighted-average number of shares of Class A and Class B common stock and potentially dilutive Class A and Class B potential common shares outstanding during the period. The Company's basic and diluted net loss per share are the same because the Company has generated net loss to common stockholders. During the three months ended March 31, 2020, the Company repurchased certain preferred units at a premium over the carrying values, which increased net loss attributable to common stockholders. As discussed in Note 1 — "Basis of Presentation and Summary of Significant Accounting Policies," immediately prior to the IPO, the Company completed the Corporate Conversion. The Corporate Conversion resulted in a change of equity interests from common units to shares of common stock, but no change in relative shareholder rights, rank, or value before and after this reorganization transaction. As such, the Corporate Conversion of common units was considered equivalent to a stock split and requires retrospective treatment for net loss per share purposes. All share and per share information has been retroactively adjusted to reflect the Corporate Conversion for all periods presented. PIUs outstanding prior to the Corporate Conversion were considered compensatory arrangements that were settled with shares of Class A or Class B common stock at the time of the Corporate Conversion and have been included as outstanding shares subsequent to that date. Similarly, any preferred units that were converted in accordance with their terms into shares of Class A or Class B common stock at the time of the Corporate Conversion have also been included as outstanding shares subsequent to that date. The following table presents the calculation of basic and diluted net loss per share for the three months ended March 31, 2021 and 2020 as follows (in thousands, except per share amounts): 2021 2020 Numerator: Net loss $ (295,033) $ (105,353) Less: premium on repurchase of redeemable convertible preferred units — (34,871) Net loss attributable to Class A and Class B common stockholders $ (295,033) $ (140,224) Denominator: Weighted-average shares used in computing net loss per share attributable to Class A and Class B common stockholders, basic and diluted 434,917 24,409 Net loss attributable to Class A and Class B common stockholders per share, basic and diluted $ (0.68) $ (5.74) The following have been excluded from the computation of basic and diluted net loss per share attributable to Class A and Class B common stockholders as their effect would have been anti-dilutive for the three months ended March 31, 2021 and 2020 (in thousands of equivalent common shares): 2021 2020 Convertible debt — 160,006 Redeemable convertible preferred units — 1,347,116 Equity compensation awards 60,187 60,451

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Principles of Consolidation	The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited consolidated financial statements as of that date. The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company’s financial position, results of operations and comprehensive loss, redeemable convertible preferred units and stockholders’/members’ equity (deficit), and cash flows for the periods presented, but are not necessarily indicative of the results of operations to be anticipated for any future annual or interim period. Certain information and note disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes included in the final prospectus dated March 10, 2021, as filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (File No. 333-253030) (“Final Prospectus”).
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates, which include, but are not limited to, equity-based compensation, inventory valuation, income taxes, defined severance benefits, and revenue recognition. Actual results could differ materially from those estimates. We based our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Given the global economic climate and additional or unforeseen effects from the COVID-19 pandemic, these estimates become more challenging, and actual results could differ materially from these estimates.
Segment Information	Segment Information The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer. The Company has determined that it operates in one operating segment and one reportable segment. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance.
Equity-based Compensation	Equity-based Compensation The Company accounts for equity-based employee compensation arrangements in accordance with U.S. GAAP, which requires compensation expense for the grant-date fair value of equity-based awards to be recognized over the requisite service period. The Company determines the fair value of equity-based awards granted or modified on the grant date or modification date using appropriate valuation techniques. Forfeitures are estimated using historical experience at the time of grant and revised in subsequent periods if actual forfeitures differ from initial estimates. Prior to the IPO, the grant-date fair value of equity-based awards was primarily determined using the estimated fair value of the Company's previously issued common units. Common unit fair value estimates were developed by considering numerous objective and subjective factors that required judgment. Subsequent to the IPO, the Company determines the fair value of its Class A common stock using the market closing price on the grant date. During the first quarter of 2021, the Company changed its policy for recognizing equity-based compensation expense from the graded vesting attribution method of accounting to the straight-line attribution method of accounting for its equity-based compensation arrangements with service only vesting conditions. For additional information, see Note 2 — "Change in Accounting Principle." Restricted Stock Units The Company had previously granted restricted equity units under its 2011 Equity Incentive Plan (“2011 Plan”), which vest upon the satisfaction of both a service-based condition and a performance-based condition. In connection with the Company’s Corporate Conversion, the outstanding awards were converted into restricted stock units (“RSUs”). Following the IPO and Corporate Conversion, the Company has granted RSUs that vest upon the satisfaction of a service-based condition as defined in the Company’s 2021 Equity Incentive Plan (“2021 Plan”). The grant-date fair value of each RSU, net of estimated forfeitures, is recognized as expense over the requisite service period. Stock Options The Company had previously granted unit options under the 2011 Plan, which vest over a service period of generally four years. In connection with the Company’s Corporate Conversion, the outstanding awards were converted into stock options. The grant-date fair value of each stock option award, net of estimated forfeitures, is recognized as expense over the requisite service period. The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing model, which requires the input of subjective assumptions, including the expected stock price volatility over the expected term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate for the expected term of the award, and expected dividends. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected term of the options for each option group. The assumptions used to determine the fair value of the option awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. Profits Interests Prior to the IPO, the Company granted common units designated as PIUs that vested upon the satisfaction of a service-based condition and with respect to certain awards, vesting accelerates upon the occurrence of an IPO. The grant-date fair value of the PIUs, net of estimated forfeitures, were recognized as expense over the requisite service period.
Concentration of Credit Risk	Concentration of Credit Risk Cash and cash equivalents, restricted cash and accounts receivable are potentially subject to concentration of credit risk. Cash and cash equivalents, and restricted cash are placed with several financial institutions that management believes are of high credit quality, of which 90% are held at five financial institutions as of March 31, 2021. The Company’s gross accounts receivable include amounts concentrated with four payment processing companies representing 72% of gross accounts receivable at March 31, 2021.
Recent Accounting Pronouncements Adopted/Recent Accounting Pronouncements Yet To Be Adopted	Recent Accounting Pronouncements Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes certain exceptions for performing intraperiod allocation, recognize deferred taxes for investments, and calculating income taxes in interim periods. The standard reduces complexity in certain areas, including franchise taxes that are partially based on income and accounting for tax law changes in interim periods. The ASU is effective for public companies for fiscal years beginning after December 15, 2020, with early adoption permitted. We adopted this ASU effective January 1, 2021. The adoption of the ASU did not have a material impact on our condensed consolidated financial statements. Recent Accounting Pronouncements Yet To Be Adopted In August 2020, the FASB issued ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40).” The standard reduces the number of models used to account for convertible instruments, amends diluted earnings per share (“EPS”) calculations for convertible instruments, and amends the requirements for a contract (or embedded derivative) that is potentially settled in an entity's own shares to be classified in equity. The amendments add certain disclosure requirements to increase transparency and decision-usefulness about a convertible instrument's terms and features. Under the amendment, the Company must use the if-converted method for including convertible instruments in diluted EPS as opposed to the treasury stock method. The ASU is effective for public companies for fiscal years beginning after December 15, 2021. Early adoption is allowed under the standard with either a modified retrospective or full retrospective method. The Company is currently evaluating this guidance to determine the impact to our condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” In January 2021, the FASB clarified the scope of this guidance with the issuance of ASU 2021-01, “Reference Rate Reform: Scope.” ASU 2020-04 provides optional expedients and exceptions to account for contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate if certain criteria are met. ASU 2020-04 may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating future impacts that may result from the potential adoption of ASU 2020-04.
