Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Principles of Consolidation	1. Description of Business and Principles of Consolidation Description of Business AppLovin Corporation (the “Company” or “AppLovin”) was incorporated apps—free-to-play The Company’s operations are headquartered in Palo Alto, California, and has several operating locations in the U.S. as well as various international office locations in North America, Asia and Europe. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, the unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s final prospectus dated April 14, 2021 and filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933 (the “Prospectus”). The condensed consolidated balance sheet data as of December 31, 2020 was derived from the audited consolidated financial statements at that date but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, that are, in the opinion of management, necessary for the fair presentation of the Company’s financial position, results of operations, cash flows and stockholders’ equity for the interim periods presented. The results of operations for the three months ended March 31, 2021 shown in this report are not necessarily indicative of the results to be expected for the full year ending December 31, 2021 or any other period. Principles of Consolidation The unaudited condensed consolidated financial statements reflect the accounts of AppLovin Corporation and its subsidiaries in which the Company has a controlling financial interest. In accordance with the provisions of Accounting Standards Codification (“ASC”) 810, Consolidation, the Company consolidates any variable interest entity (“VIE”) of which the Company is the primary beneficiary. The Company engages in business relationships with certain entities in the ordinary course of business to develop game Apps. The typical condition for a controlling financial interest ownership is holding a majority of the voting interests of an entity; however, a controlling financial interest may also exist in entities, such as VIEs, through arrangements that do not involve controlling voting interests. ASC 810 requires a variable interest holder to consolidate a VIE if that party has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company does not consolidate a VIE in which it has a majority ownership interest when the Company is not considered the primary beneficiary. The Company evaluates its relationships with all VIEs on an ongoing basis. All intercompany transactions and balances have been eliminated upon consolidation. Initial Public Offering and Capital Structure Change The Company’s registration statement on Form S-1 reimbursements. KKR Capital Markets LLC was is million of the net proceeds from the IPO to repay the entire outstanding amount under the revolving credit facility (See Note 8). KKR Capital Markets LLC is a lender under the revolving credit facility and an affiliate of KKR Denali, a principal stockholder of the Company. Following the effectiveness of the IPO Registration Statement, the Company filed its Amended and Restated Certificate of Incorporation, which became effective immediately prior to the closing of the IPO (the “IPO Certificate”). The IPO Certificate authorizes a total of 1,500,000,000 shares of Class A common stock, 200,000,000 shares of Class B common stock, 150,000,000 shares of Class C common stock, and 100,000,000 shares of preferred stock. Upon the filing and effectiveness of the IPO Certificate, a ll and 150, 7 2 Company’s co-founder, CEO, Following the closing of the IPO, the Company had two classes of outstanding common stock: Class A common stock and Class B common stock. No shares of the Company’s Class C common stock or preferred stock were issued and outstanding. The rights of the holders of all classes of stock pursuant to the IPO Certificate are as follows: Common Stock The rights of the holders of Class A common stock, Class B common stock, and Class C common stock (referred to together as the “common stock”) are identical, except with respect to voting and conversion. Voting Rights Holders of the Class A common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders, holders of the Class B common stock are entitled to 20 votes for each share held on all matters submitted to a vote of stockholders, and holders of the Class C common stock are not entitled to vote on any matter that is submitted to a vote of stockholders, except as otherwise required by law. The holders of the Class A common stock and Class B common stock will vote together as a single class, unless otherwise required by law. Under the IPO Certificate, approval of the holders of at least a majority of the outstanding shares of the Class B common stock voting as a separate class will be required to increase the number of authorized shares of the Class B common stock. In addition, Delaware law could require either holders of the Class A common stock, the Class B common stock, or the Class C common stock to vote separately as a single class in the following circumstances: • if the Company were to seek to amend the IPO Certificate to increase or decrease the par value of a class of stock, then that class would be required to vote separately to approve the proposed amendment; and • if the Company were to seek to amend the IPO Certificate in a manner that alters or changes the powers, preferences or special rights of a class of stock in a manner that affected its holders adversely, then that class would be required to vote separately to approve the proposed amendment. Until the date on which the final conversion of all outstanding shares of Class B common stock pursuant to the terms of the IPO Certificate occurs, approval of at least two-thirds Upon the closing of the IPO, the Class B Stockholders held all of the issued and outstanding shares of the Company’s Class B common stock. The Class B Stockholders have Dividend Rights Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of the Company’s common stock will be entitled to receive dividends out of funds legally available if the Company’s board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that the Company’s board of directors may determine. No Preemptive or Similar Rights The Company’s common stock will not be entitled to preemptive rights, and is not subject to conversion, redemption or sinking fund provisions. Right to Receive Liquidation Distributions If the Company becomes subject to a liquidation, dissolution or winding-up, Conversion of Class B Common Stock Each share of Class B common stock will be convertible at any time at the option of the holder into one share of Class A common stock. Following the closing of the IPO, shares of Class B common stock will automatically convert into shares of Class A common stock upon sale or transfer except for certain transfers described in the IPO Certificate, including transfers for estate planning, transfers among KKR Denali and its affiliates, or other transfers among the Class B Stockholders. Withdrawal from the Voting Agreement constitutes a transfer. Each share of Class B common stock will convert automatically into one share of Class A common stock upon the date fixed by the Company’s board of directors that is no less than 61 days and no more than 180 days following the date on which (i) the Voting Agreement is terminated or (ii) Adam Foroughi is no longer involved with the Company as a member of the board of directors or as an executive officer. Conversion of Class C Common Stock After the conversion or exchange of all outstanding shares of the Company’s Class B common stock into shares of Class A common stock, all outstanding shares of Class C common stock will convert automatically into Class A common stock, on a share-for-share Preferred Stock The Company’s IPO Certificate also authorizes the issuance of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by the board of directors.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Revenue from Contracts with Customers The Company generates Business and Consumer revenue. Business Revenue includes fees paid by mobile app advertisers that use the Company’s software platform (“Software Platform”), and revenue generated from the sale of digital advertising inventory of the Company’s apps (“Apps”). Consumer Revenue consists of mobile in-app Business Revenue Our Software Platform provides the technology to match advertisers and third-party owners of digital advertising inventory (“Publishers”) via auctions at large scale and microsecond-level speeds. The pricing and terms for all mobile advertising arrangements are governed by the Company’s terms and conditions and generally stipulate payment terms of 30 days subsequent to the end of the month. The contract is fully cancellable at any time. For Business Revenue generated through placement of advertisements on mobile applications owned by Publishers, the Company’s performance obligation is to provide an advertiser with access to our Software Platform which facilitates the advertiser’s purchase of advertising inventory from Publishers. The Company does not control the advertising inventory prior to its transfer to the advertiser, the Company’s customer, because the Company does not have the substantive ability to direct the use of, nor obtain substantially all of the remaining benefits from the advertising inventory. The Company is not primarily responsible for fulfillment and does not have any inventory risk. The Company is an agent as it relates to the sale of third-party advertising inventory and presents revenue on a net basis. The transaction price is the product of either the number of completions of agreed upon actions or advertisements displayed and the contractually agreed upon price per advertising unit with the advertiser less consideration paid or payable to Publishers. Advertisers purchase Apps advertising inventory either through the Software Platform or through third-party advertising networks (“Ad Networks”). Revenue from the sale of advertising inventory through Ad Networks is recognized net of the amounts retained by Ad Networks as the Company is unable to determine the gross amount paid by the advertisers to Ad Networks. The Company recognizes mobile advertising revenue when the agreed upon action is completed or when the ad is displayed to users, depending on the agreed upon pricing mechanism with an advertiser or Ad Network. The number of advertisements delivered and completions of agreed upon actions is determined at the end of each month, which resolves any uncertainty in the transaction price during the reporting period. Consumer Revenue IAPs include fees collected from users for the purchase of virtual goods to enhance their gameplay experience. The identified performance obligation is to provide users with the ability to acquire, use, and hold virtual items over the estimated period of time the virtual items are available to the user or until the virtual item is consumed. The Company categorizes its virtual goods as either consumable or durable. Consumable virtual goods represent goods that can be consumed by a specific player action in gameplay; accordingly, the Company recognizes revenue from the sale of consumable virtual goods as the goods are consumed and the Company’s performance obligation is satisfied. Durable virtual goods represent goods that are accessible to the user over an extended period of time; accordingly, the Company recognizes revenue from the sale of durable virtual goods ratably over the period of time the goods are available to the user and the Company’s performance obligation is satisfied, which is generally the estimated average user life (“EAUL”). Payment is required at the time of purchase and the purchase price is a fixed amount. Users make IAPs through the Company’s distribution partners. The transaction price is equal to the gross amount charged to users because the Company is the principal in the transaction. IAPs fees are non-refundable. The EAUL represents the Company’s best estimate of the expected life of paying users for the applicable game. The EAUL begins when a user makes a first purchase of durable virtual goods and ends when a user is determined to be inactive. The Company determines the EAUL on a game-by-game The Company presents taxes collected from customers and remitted to governmental authorities on a net basis. Asset Acquisitions and Business Combinations The Company performs an initial test to determine whether substantially all of the fair value of the gross assets transferred are concentrated in a single identifiable asset or a group of similar identifiable assets, such that the acquisition would not represent a business. If that test suggests that the set of assets and activities is a business, the Company then performs a second test to evaluate whether the assets and activities transferred include inputs and substantive processes that together, significantly contribute to the ability to create outputs, which would constitute a business. If the result of the second test suggests that the acquired assets and activities constitute a business, the Company accounts for the transaction as a business combination. For transactions accounted for as business combinations, the Company allocates the fair value of acquisition consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. Acquisition consideration includes the fair value of any promised contingent consideration. The excess of the fair value of acquisition consideration over the fair value of acquired identifiable assets and liabilities is recorded as goodwill. Contingent consideration is remeasured to its fair value each reporting period with changes in the fair value of contingent consideration recorded in general and administrative expenses. Such valuations require management to make significant estimates and assumptions, especially with respect to 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. In certain circumstances, the allocations of the excess purchase price are based upon preliminary estimates and assumptions and subject to revision when the Company receives final information, including appraisals and other analyses. During the measurement period, which is one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. Acquisition-related costs are expensed as incurred. For transactions accounted for as asset acquisitions, the cost, including certain transaction costs, is allocated to the assets acquired on the basis of relative fair values. The Company generally includes contingent consideration in the cost of the assets acquired only when the uncertainty is resolved. The Company recognizes contingent consideration adjustments to the cost of the acquired assets prospectively using the straight-line method over the remaining useful life of the assets. No goodwill is recognized in asset acquisitions. Services and Development Agreements The Company enters into strategic agreements with mobile gaming studios (“Partner Studios”). The Company has historically allowed these Partner Studios to continue their operations with a significant degree of autonomy. In some cases, the Company bought Apps from Partner Studios and entered into service and development agreements whereby Partner Studios provide support in improving existing Apps and developing new Apps. The substantial majority of payments associated with service agreements for existing Apps are expensed to research and development when the services are rendered as the payments primarily relate to developing enhancements for the Apps. Payments for new Apps associated with development agreements are generally made in connection with the development of a particular App, and therefore, the Company is subject to development risk prior to the release of the App. Accordingly, payments that are due prior to completion of an App are generally expensed to research and development over the development period as the services are incurred.

Fair Value Measurements	4. Fair Value Measurements The following table sets forth the Company’s financial instruments that were measured at fair value by level within the fair value hierarchy on a recurring basis as of the dates indicated (in thousands): As of March 31, 2021 Balance Sheet Location Total Level 1 Level 2 Level 3 Financial Assets: Money market funds Cash and cash equivalents $ 477 $ 477 $ — $ — Marketable equity securities Prepaid expenses and other current assets 5,354 5,354 — — Embedded derivative Long-term debt 16,740 — — 16,740 Total financial assets $ 22,571 $ 5,831 $ — $ 16,740 Financial Liability: Convertible security Deferred acquisition costs, current $ 47,200 $ — $ — $ 47,200 As of December 31, 2020 Balance Sheet Location Total Level 1 Level 2 Level 3 Financial Assets: Money market funds Cash and cash equivalents $ 6,413 $ 6,413 $ — $ — Embedded derivative Long-term debt 5,680 — — 5,680 Total financial assets $ 12,093 $ 6,413 $ — $ 5,680 Financial Liability: Convertible security Deferred acquisition costs, current $ 46,500 $ — $ — $ 46,500 Convertible Security In November 2020, the Company issued a convertible security as part of the consideration exchanged for certain mobile game Apps acquired from an independent foreign-based mobile game developer. The Company elected to account for the convertible security using the fair value option. Under the fair value option, the financial liability is initially measured at its issue-date estimated fair value and subsequently remeasured at estimated fair value on a recurring basis at each reporting period date. The fair value of the convertible security was determined using the probability-weighted expected return method (“PWERM”). This valuation methodology is based on unobservable estimates and judgements, and therefore is classified as a Level 3 fair value measurement. The significant unobservable input used in the fair value measurement of the convertible security is the expected timing of occurrence of an IPO. Fair value measurements are highly sensitive to changes in this input and significant changes in this input would result in a significantly higher or lower fair value. For the three months ended March 31, 2021, the Company recorded a total loss of $0.7 million in other income, net in the Company’s condensed consolidated statements of operations due to the change in fair value of the convertible security. The convertible security is included in deferred acquisition costs, current, in the Company’s condensed consolidated balance sheets. Embedded Derivative Loans issued under Company’s credit agreement with the lenders party thereto and Bank of America, N.A., as administrative agent for the lenders (the “Credit Agreement”) contain certain interest adjustment features which were determined to be an embedded derivative requiring bifurcation and separate accounting as the features are not clearly and closely related to the host debt instrument. The embedded derivative was initially valued and remeasured using the “with-and-without” method. The “with-and-without” methodology involves valuing the whole instrument with and without the embedded derivative using a discounted cash flow approach. The difference of the estimated fair value between the instrument with the embedded derivative and the instrument without the embedded derivative is the fair value of the embedded derivative. This valuation methodology is based on unobservable estimates and judgements, and therefore is classified as a Level 3 fair value measurement. The significant unobservable input used in the fair value measurement of the embedded derivative is the expected timing of occurrence of an IPO. Fair value measurements are highly sensitive to changes in these inputs and significant changes in these inputs would result in a significantly higher or lower fair value. The initial fair value of the embedded derivative was determined to be nominal for term loans issued prior to 2021 and 5.6 million for the term loans issued in February 2021, which was accounted for as a reduction to the carrying amount of the term loans. For the three months ended March 31, 2021 and 2020, the Company recorded a total gain of 6.6 million and nil, respectively, in other income, net in the Company’s condensed consolidated statements of operations due to the change in fair value of the embedded derivative. Marketable Equity Securities The Company’s marketable equity securities consist entirely of its investment in the ordinary shares of Huuuge, Inc., a foreign based independent mobile game developer, which completed its initial public offering and became listed on the Warsaw Stock Exchange in the first quarter of 2021. The Company had carried the investment at cost in other assets on the Company’s consolidated balance sheets in prior fiscal years. The cost basis of the investment was immaterial. The fair value of the marketable equity securities was based on the quoted market price of Huuuge, Inc.’s ordinary shares as of March 31, 2021, and therefore was classified as a Level 1 fair value measurement. For the three months ended March 31, 2021, the Company recorded a total unrealized gain of $5.4 million in other income, net in the Company’s condensed consolidated statements of operations as a result of remeasuring the investment to fair value. The following table presents a reconciliation of the Company’s financial asset and liability measured at fair value as of March 31, 2021 using significant unobservable inputs (Level 3), and the change in fair value (in thousands): Embedded Derivative Convertible Security Balance as of December 31, 2020 $ 5,680 $ 46,500 Addition related to the issuance of term loans in February 2021 5,630 — Extinguishment of term loans in February 2021 (1,130 ) — Change in fair value recognized in earnings 6,560 700 Balance as of March 31, 2021 $ 16,740 $ 47,200

Commitments and Contingencies Disclosure [Abstract]
Contingencies	5. Contingencies Contingencies From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities. The Company accrues a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. Letters of Credit As of March 31, 2021 and December 31, 2020 the Company had outstanding letters of credit in the aggregate amount of $11.1 million, which were issued as security for certain leased office facilities under the Credit Agreement. These letters of credit have never been drawn upon. Legal Proceedings The Company is involved from time to time in litigation, claims, and proceedings. The outcomes of the Company’s legal proceedings are inherently unpredictable and subject to significant uncertainty. The Company records a liability when it is probable that a loss has been incurred and the amount can be reasonably estimated. If it is determined that a loss is reasonably possible and the loss or range of loss can be estimated, the reasonably possible loss is disclosed. The Company evaluates developments in legal matters that could affect the amount of liability that has been previously accrued, and related reasonably possible losses disclosed, and makes adjustments as appropriate. Significant judgment is required to determine the likelihood of matters and the estimated amount of losses related to such matters. To date, losses in connection with legal proceedings have not been material. The Company expenses legal fees in the period in which they are incurred. Indemnifications The Company enters into indemnification provisions under agreements with other parties in the ordinary course of business, including certain customers, business partners, investors, contractors and the Company’s officers, directors and certain employees. It is not possible to determine the maximum potential loss under these indemnification provisions due to the Company’s limited history of prior indemnification claims and the unique facts and circumstances involved in each particular provision. To date, losses recorded in the Company’s condensed consolidated statements of operations in connection with the indemnification provisions have not been material. As of March 31, 2021, the Company did not have any material indemnification claims that were probable or reasonably possible. Non-income The Company may be subject to audit by various tax authorities with regard to non-income non-income non-income

Acquisitions	6. Acquisitions 2021 Acquisitions In February 2021, the Company signed a share purchase agreement with Adjust GmbH, a leading mobile app attribution, measurement and analytics company in Germany, which agreement, as amended and restated and further amended, provides for the Company to acquire all the outstanding shares of Adjust GmbH for (i) $ 598.0 352.0 trading days commencing with and following the closing of the IPO (the “Conversion Price”); and (iii) the assumption of up to 40.0 million in the aggregate of debt, accrued interest, and fees of Adjust, in each case upon the terms and subject to the conditions of the share purchase agreement. The transaction closed on April 20, 2021. The 20-day trading period expired on May 12. As of the date of issuance of these condensed consolidated financial statements, the Company has not received any notice designating the 10-day period for determining the Conversion Price. Due to the timing of this transaction close, as of the date of issuance of these condensed consolidated financial statements, the Company is in the process of finalizing the valuation and related accounting impact. During the three months ended March 31, 2021, the Company recognized earn-out 27.2 million related to the Zenlife acquisition closed in 2020. These earn-out costs increased the book value of the acquired mobile game Apps, and are amortized over the remaining useful life of the originally acquired game Apps. During the three months ended March 31, 2021, the Company also acquired certain mobile game Apps for an aggregated consideration of $8.6 million . In January 2021 the Company paid $60.0 million to Recoded, an independent foreign-based mobile game developer, in relation to a new game App acquired in 2020. In February 2021, the Company paid an additional $90.0 million to Recoded related to deferred cash consideration on the acquisition closed in 2019. 2020 Acquisitions Geewa million indemnity holdback that was paid in January 2021. Transaction costs incurred by the Company in connection with the acquisition, including professional fees, were The following table summarizes the fair value of identifiable assets acquired and liabilities assumed (in thousands): Cash $ 1,043 Accounts receivable and other current assets 1,457 Intangible assets Apps—estimated useful life of 5 years 17,040 Tradename—estimated useful life of 5 years 260 Developed Technology—estimated useful life of 2 years 590 Property, equipment and other tangible assets 369 Goodwill 9,805 Accounts payable, accrued liabilities and other liabilities (4,935 ) Total purchase consideration $ 25,629 The income approach was used to value the developed Apps and tradename. Goodwill represents the excess of the purchase price over the fair value of the identifiable assets and assumed liabilities acquired and is primarily attributable to the assembled workforce and expected synergies at the time of the acquisition. Goodwill is not deductible for tax purposes. Pro forma results of operations have not been presented because the effect of the acquisition was not material to the condensed consolidated statements of operations. In March 2020, the Company completed a transaction to acquire a certain mobile game App from an independent foreign-based mobile game developer in exchange for an upfront cash consideration of $30.0 million and earn-out payments. The transaction was accounted for as an asset acquisition with the entire upfront cash consideration allocated to the acquired mobile game App. Additionally, the Company entered into a service and development agreement with the independent mobile game developer to support the initially acquired game App as well as to develop new game Apps. The earn-out payments are based on a predetermined percentage of revenue net of certain direct costs generated by the initially acquired game App, or additional game Apps developed under the service and development agreement, over the term of the agreement, which is initially two years, but which may renew for an additional two-year term. During the three months ended March 31, 2021 and 2020, the earn-outs incurred in connection with this acquisition were immaterial.

Credit Agreement	8. Credit Agreement On August 15, 2018, the Company entered into a Credit Agreement which provided for senior secured term loans in an aggregate principal amount of $820.0 million (the “Closing Term Loans”) and a revolving credit facility of $50.0 million. On April 23, 2019, the Credit Agreement was amended to increase the senior secured term loan facility by $ million, on terms identical to those applicable to the Closing Term Loans (together with the Closing Term Loans, the “Initial Term Loans”). On April 27, 2020, the Credit Agreement was further amended to modify certain negative covenants. On May 6, 2020, the Credit Agreement was further amended (the “Third Amendment”) to increase the senior secured term loan facility by an additional $ million (the “Third Amendment Term Loans”). On October 27, 2020, the Credit Agreement was further amended to increase the aggregate principal amount of the revolving credit facility by an additional $540.0 million. On November 30, 2020, the Company borrowed $150.0 million under the revolving credit facility. On February 12, 2021, the Company amended the Credit Agreement to 1) increase the senior secured term loan facility by an aggregate principal amount of $ million (the “Fifth Amendment Term Loans”, and together with the Initial Term Loans, the “Term Loans”), on terms identical to those applicable to the existing Initial Term Loans, the proceeds of which was partially used to repay in full the outstanding principal and accrued and unpaid interest of the Third Amendment Term Loans, totaling $ million, in accordance with the pre-existing early redemption option in the Credit Agreement, and 2) increase the aggregate principal amount of the revolving credit facility by an additional $ million, on terms identical to those applicable to the existing revolving credit facility. According to the amended Credit Agreement, the Company is required to make equal quarterly repayments of $ million with respect to the Term Loans. In connection with this amendment, the Company paid $ million in fees to KKR Capital Markets LLC, who is affiliated with KKR Denali, one of the Company’s principal stockholders. The Company evaluated the accounting for the Fifth Amendment Term Loans on a creditor-by-creditor n %. For new creditors, the transaction was accounted for as an issuance of new debt. As a result, $ million of the $ million third-party issuance costs related to the modified debt was recorded in other income, net on the Company’s condensed consolidated statements of operations for the three months ended March 31, 2021, with the remaining million related to the new debt recorded as a reduction to the carrying amount of the Term Loans. In addition, the Company recorded $ million for an embedded derivative related to the contingent interest adjustment feature of the Fifth Amendment Term Loans, which was bifurcated and accounted for separately as the feature is not clearly and closely related to the host instrument. For details regarding the fair value measurement of the embedded derivative, see Note 4.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	11. Net Income (Loss) Per Share Basic and diluted net income (loss) per share attributable to common stockholders is computed in conformity with the two-class method required for participating securities. The Company considers its convertible preferred stock, options exercised in exchange for nonrecourse promissory notes, early exercised unvested stock options and unvested restricted stock awards to be participating securities. Under the two-class method, the net loss attributable to common stockholders is not allocated to convertible preferred stock, options exercised in exchange for nonrecourse promissory notes, early exercised unvested common stock options and unvested restricted stock awards as the holders of these instruments do not have a contractual obligation to share in the Company’s losses. Net income is attributed to common stockholders and participating securities based on their participation rights. Basic net loss per share attributable to common stockholders 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. Diluted earnings per share attributable to common stockholders adjusts basic earnings per share for the potentially dilutive impact of stock options.

Subsequent Events [Abstract]
Subsequent Events	1 4 In April 2021, the Company completed two separate transactions to acquire certain mobile game Apps from two foreign based independent mobile game developers in exchange for an aggregate upfront cash consideratio n million and potential future earn-out payments. Concurrent with the closings of these transactions, the Company entered into a development services agreement with each of the independent mobile game developers to support the acquired mobile game Apps, as well as to develop new game Apps during the four-year term of the agreement. With respect to the first transaction, the potential future earn-out payments are contingent on the revenue generated by the acquired game Apps exceeding a certain revenue threshold, which will be measured and payable (if applicable) each year for four years from the date of the transaction. With respect to the second transaction, the potential future earn-out payments will be determined in a manner similar to the first transaction, in addition to a potential one-time earn-out payment of $50.0 million contingent on the achievement of a certain monthly revenue milestone within the four years following the date of the transaction. Due to the timing of these transactions, as of the date of issuance of these condensed consolidated financial statements, the Company is in the process of finalizing the valuation and related accounting for these transactions. In May 2021, the Company granted 6,038,514 RSUs to certain employees under the 2021 Plan at the grant date fair value of $58.55 per RSU. The RSUs generally vest either over four In May 2021, the Company amended a certain agreement with a cloud service provider to increase the aggregate spend commitment from $130.0 million to $300.0 million through May 2026.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers The Company generates Business and Consumer revenue. Business Revenue includes fees paid by mobile app advertisers that use the Company’s software platform (“Software Platform”), and revenue generated from the sale of digital advertising inventory of the Company’s apps (“Apps”). Consumer Revenue consists of mobile in-app Business Revenue Our Software Platform provides the technology to match advertisers and third-party owners of digital advertising inventory (“Publishers”) via auctions at large scale and microsecond-level speeds. The pricing and terms for all mobile advertising arrangements are governed by the Company’s terms and conditions and generally stipulate payment terms of 30 days subsequent to the end of the month. The contract is fully cancellable at any time. For Business Revenue generated through placement of advertisements on mobile applications owned by Publishers, the Company’s performance obligation is to provide an advertiser with access to our Software Platform which facilitates the advertiser’s purchase of advertising inventory from Publishers. The Company does not control the advertising inventory prior to its transfer to the advertiser, the Company’s customer, because the Company does not have the substantive ability to direct the use of, nor obtain substantially all of the remaining benefits from the advertising inventory. The Company is not primarily responsible for fulfillment and does not have any inventory risk. The Company is an agent as it relates to the sale of third-party advertising inventory and presents revenue on a net basis. The transaction price is the product of either the number of completions of agreed upon actions or advertisements displayed and the contractually agreed upon price per advertising unit with the advertiser less consideration paid or payable to Publishers. Advertisers purchase Apps advertising inventory either through the Software Platform or through third-party advertising networks (“Ad Networks”). Revenue from the sale of advertising inventory through Ad Networks is recognized net of the amounts retained by Ad Networks as the Company is unable to determine the gross amount paid by the advertisers to Ad Networks. The Company recognizes mobile advertising revenue when the agreed upon action is completed or when the ad is displayed to users, depending on the agreed upon pricing mechanism with an advertiser or Ad Network. The number of advertisements delivered and completions of agreed upon actions is determined at the end of each month, which resolves any uncertainty in the transaction price during the reporting period. Consumer Revenue IAPs include fees collected from users for the purchase of virtual goods to enhance their gameplay experience. The identified performance obligation is to provide users with the ability to acquire, use, and hold virtual items over the estimated period of time the virtual items are available to the user or until the virtual item is consumed. The Company categorizes its virtual goods as either consumable or durable. Consumable virtual goods represent goods that can be consumed by a specific player action in gameplay; accordingly, the Company recognizes revenue from the sale of consumable virtual goods as the goods are consumed and the Company’s performance obligation is satisfied. Durable virtual goods represent goods that are accessible to the user over an extended period of time; accordingly, the Company recognizes revenue from the sale of durable virtual goods ratably over the period of time the goods are available to the user and the Company’s performance obligation is satisfied, which is generally the estimated average user life (“EAUL”). Payment is required at the time of purchase and the purchase price is a fixed amount. Users make IAPs through the Company’s distribution partners. The transaction price is equal to the gross amount charged to users because the Company is the principal in the transaction. IAPs fees are non-refundable. The EAUL represents the Company’s best estimate of the expected life of paying users for the applicable game. The EAUL begins when a user makes a first purchase of durable virtual goods and ends when a user is determined to be inactive. The Company determines the EAUL on a game-by-game The Company presents taxes collected from customers and remitted to governmental authorities on a net basis.
Asset Acquisitions and Business Combinations	Asset Acquisitions and Business Combinations The Company performs an initial test to determine whether substantially all of the fair value of the gross assets transferred are concentrated in a single identifiable asset or a group of similar identifiable assets, such that the acquisition would not represent a business. If that test suggests that the set of assets and activities is a business, the Company then performs a second test to evaluate whether the assets and activities transferred include inputs and substantive processes that together, significantly contribute to the ability to create outputs, which would constitute a business. If the result of the second test suggests that the acquired assets and activities constitute a business, the Company accounts for the transaction as a business combination. For transactions accounted for as business combinations, the Company allocates the fair value of acquisition consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. Acquisition consideration includes the fair value of any promised contingent consideration. The excess of the fair value of acquisition consideration over the fair value of acquired identifiable assets and liabilities is recorded as goodwill. Contingent consideration is remeasured to its fair value each reporting period with changes in the fair value of contingent consideration recorded in general and administrative expenses. Such valuations require management to make significant estimates and assumptions, especially with respect to 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. In certain circumstances, the allocations of the excess purchase price are based upon preliminary estimates and assumptions and subject to revision when the Company receives final information, including appraisals and other analyses. During the measurement period, which is one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. Acquisition-related costs are expensed as incurred. For transactions accounted for as asset acquisitions, the cost, including certain transaction costs, is allocated to the assets acquired on the basis of relative fair values. The Company generally includes contingent consideration in the cost of the assets acquired only when the uncertainty is resolved. The Company recognizes contingent consideration adjustments to the cost of the acquired assets prospectively using the straight-line method over the remaining useful life of the assets. No goodwill is recognized in asset acquisitions.
Services and Development Agreements	Services and Development Agreements The Company enters into strategic agreements with mobile gaming studios (“Partner Studios”). The Company has historically allowed these Partner Studios to continue their operations with a significant degree of autonomy. In some cases, the Company bought Apps from Partner Studios and entered into service and development agreements whereby Partner Studios provide support in improving existing Apps and developing new Apps. The substantial majority of payments associated with service agreements for existing Apps are expensed to research and development when the services are rendered as the payments primarily relate to developing enhancements for the Apps. Payments for new Apps associated with development agreements are generally made in connection with the development of a particular App, and therefore, the Company is subject to development risk prior to the release of the App. Accordingly, payments that are due prior to completion of an App are generally expensed to research and development over the development period as the services are incurred. Payments due after completion of an App are generally capitalized and expensed as cost of revenue. See Note 6, “Acquisitions” for additional information.
