Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation and principles of consolidation The accompanying interim condensed consolidated financial statements of the Company are unaudited. These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), on the same basis as the audited consolidated financial statements, and in management’s opinion, reflect all adjustments, consisting only of normal, recurring adjustments, that are necessary for the fair statement of the Company’s condensed consolidated balance sheet as of September 30, 2021, condensed consolidated results of operations for the three and nine months ended September 30, 2021 and September 30, 2020, and condensed consolidated statements of cash flows for the nine months ended September 30, 2021 and September 30, 2020. The unaudited condensed consolidated results of operations for the three and nine months ended September 30, 2021 and September 30, 2020 are not necessarily indicative of the results to be expected for the full year or any other period. These 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 filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on April 14, 2021 (the “Prospectus”). These accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. The Company’s subsidiaries are entities in which the Company holds, directly or indirectly, more than 50% of the voting rights or where it exercises control. Certain subsidiaries of the Company have a basis of presentation different from GAAP. For the purposes of these unaudited condensed consolidated financial statements, the basis of presentation of such subsidiaries is converted to GAAP. All intercompany accounts and transactions have been eliminated in consolidation. There were no changes to the significant accounting policies or recent accounting pronouncements that were disclosed in Note 2. Summary of Significant Accounting Policies to the audited consolidated financial statements included in the Prospectus, other than as discussed below. Reclassifications Certain prior period amounts have been reclassified in order to conform with the current period presentation. These reclassifications have no impact on the Company’s previously reported consolidated net income. Use of estimates The preparation of the condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions in the Company’s condensed consolidated financial statements and notes thereto. Significant estimates and assumptions include the determination of the recognition, measurement, and valuation of current and deferred income taxes; the fair value of stock-based awards issued; the useful lives of intangible assets; the useful lives of property and equipment; the impairment of long-lived assets; the Company’s incremental borrowing rate; the fair value of assets acquired and liabilities assumed in business combinations, including contingent consideration arrangements; the fair value of derivatives and related hedges; the fair value of long-term debt; and loss provisions. Actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties. To the extent that there are material differences between these estimates and actual results, the Company’s condensed consolidated financial statements will be affected. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the result of which forms the basis for making judgments about the carrying values of assets and liabilities. Business combinations The results of businesses acquired in a business combination are included in the Company’s condensed consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Acquisition-related costs incurred by the Company are recognized as an expense in General and administrative expenses within the condensed consolidated statements of operations. The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, and to the extent that the value was not previously finalized, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information about facts and circumstance that existed at the date of acquisition and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill, provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statements of operations. Accounts and loans receivable and allowance for doubtful accounts Accounts and loans receivables are contractual rights to receive cash either on demand or on fixed or determinable dates, and are recognized as an asset on the Company’s balance sheet. Accounts and loans receivable consists of in-transit customer receivables, post-trade credit receivables, custodial fee revenue receivable, loans receivable, interest receivable, and other receivables. In-transit customer receivables represent settlements from third-party payment processors and banks for customer transactions. In-transit receivables are typically received within one or two business days of the transaction date. The Company establishes withdrawal-based limits in order to mitigate potential losses by preventing customers from withdrawing the crypto asset to an external blockchain address until the payment settles. In certain jurisdictions, in-transit customer receivables qualify as eligible liquid assets to meet regulatory requirements to fulfill the Company’s direct obligations under custodial funds due to customers. Post-trade credit receivables represent funds due for crypto assets delivered to credit eligible customers and are typically received within three business days from the transaction date. Post-trade credit receivables enable customers to instantly invest in crypto assets without pre-funding their trade. Custodial fee revenue receivable represents the fee earned and receivable by the Company for providing a dedicated secure cold storage solution to customers. The fee is based on a contractual percentage of the daily value of assets under custody and is collected on a monthly basis. Such custodial fee revenue income is included in the net revenue in the condensed consolidated statements of operations. Loans receivable represent loans made to retail users and institutions. These loans are collateralized with crypto assets held by those users in their crypto asset wallet on the Company’s platform. Loans receivable are subsequently measured at amortized cost. The Company recognizes an allowance for doubtful accounts for receivables based on expected credit losses. In determining expected credit losses, the Company considers historical loss experience, the aging of its receivable balance, and the fair value of any collateral held. For loans receivable, the Company applies the collateral maintenance provision practical expedient. The Company would recognize credit losses on these loans if there is a collateral shortfall and it is not reasonably expected that the borrower will replenish such a shortfall. Concentration of credit risk The Company’s cash, cash equivalents, restricted cash, customer custodial funds, and accounts and loans receivable are potentially subject to concentration of credit risk. Cash, cash equivalents, restricted cash, and customer custodial funds are placed with financial institutions which are of high credit quality. The Company invests cash, cash equivalents, and customer accounts primarily in highly liquid, highly rated instruments which are uninsured. The Company may also have deposit balances with financial institutions which exceed the Federal Deposit Insurance Corporation insurance limit of $250,000. The Company also holds cash at crypto trading venues and performs a regular assessment of these crypto trading venues as part of its risk management process. The Company held $92.1 million and $48.9 million of USD Coin (“USDC”) as of September 30, 2021 and December 31, 2020, respectively. The underlying U.S. dollar denominated assets are recognized by the issuer in U.S. regulated financial institutions on behalf of USDC holders. As of September 30, 2021, the Company had no customers who accounted for more than 10% of the Company’s accounts and loans receivable. As of December 31, 2020, two customers accounted for more than 10% of the Company’s accounts and loans receivable. One customer had fiat of $45.0 million transferred to their platform account prior to December 31, 2020, but the Company had not yet settled the transaction by collecting payment. The Company had extended $20.5 million of post trade credit to the second customer as of December 31, 2020. As these customers had transferred or were in the process of transferring funds to their portfolio equal to or in excess of the crypto assets purchased, the Company did not record an allowance for doubtful accounts. As of September 30, 2021 and December 31, 2020, the Company had no payment processors or bank partners representing more than 10% of accounts and loans receivable. During the three and nine months ended September 30, 2021 and September 30, 2020, no customer accounted for more than 10% of total revenue. Recent accounting pronouncements Recently adopted accounting pronouncements On August 5, 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40) (“ASU 2020-06”). ASU 2020-06 simplifies accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity, by removing certain separation models that require the separation of a convertible debt instrument into a debt component and an equity or derivative component. ASU 2020-06 removes from U.S. GAAP the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. After adoption of ASU 2020-06 entities will not separately present in equity an embedded conversion feature in such debt. Instead entities will account for a convertible debt instrument wholly as debt, and for convertible preferred stock wholly as preferred stock (i.e., as a single unit of account), unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC 815 or (2) a convertible instrument was issued at a substantial premium. ASU 2020-06 also expands disclosure requirements for convertible instruments and simplifies areas of the guidance for diluted earnings-per-share calculations that are impacted by the amendments. Under ASU 2020-06, entities must apply the more dilutive of the if-converted method and the two-class method to all convertible instruments; the treasury stock method is no longer available. ASU 2020-06 eliminates an entity’s ability to overcome the presumption of share settlement, and as a result, the issuers of convertible debt that may be settled in any combination of cash or stock at the issuer’s option, must use the more dilutive among the if-converted method and the two-class method in computing diluted net income per share, which is typically more dilutive than the net share settlement under the treasury stock method. ASU 2020-06 is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted. The Company early adopted ASU 2020-06 on January 1, 2021. The adoption of this new guidance did not have an impact on the Company’s consolidated financial statements since the Company had no existing convertible notes prior to issuance of the 2026 Convertible Notes, described below, in the second quarter of 2021. Further, the Company’s outstanding convertible preferred stock, which were converted into common stock in conjunction with the Company’s direct listing of its Class A common stock on the Nasdaq Global Select Market (the “Direct Listing”), did not contain any beneficial conversion feature. The Company’s 2026 Convertible Notes are accounted for in accordance with this new guidance. See Note 9. Indebtedness for additional information. On December 18, 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes: Simplifying the Accounting for Income Taxes , as part of its overall simplification initiative to reduce the costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements. Among other things, the new guidance simplifies intraperiod tax allocation and reduces the complexity in accounting for income taxes with year-to-date losses in interim periods. The Company adopted the standard on January 1, 2021. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements. On August 29, 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40)—Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which aligns the accounting for implementation costs incurred in a hosting arrangement that is a service contract with the accounting for implementation costs incurred to develop or obtain internal-use software under Accounting Standards Codification (“ASC”) 350-40, in order to determine which costs to capitalize and recognize as an asset and which costs to expense. The Company adopted the standard on January 1, 2021 using the prospective transition approach. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements. On June 16, 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 replaces the “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. For available-for-sale debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. It also simplifies the accounting model for purchased credit-impaired debt securities and loans. The Company adopted the standard on January 1, 2021 using the modified retrospective approach. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements, as the Company’s receivables are either fully collateralized or are short term in nature and therefore less susceptible to risks and uncertainty of credit losses over extended periods of time.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS2021 Acquisitions Bison Trails On February 8, 2021, the Company completed the acquisition of Bison Trails Co. (“Bison Trails”) by acquiring all issued and outstanding common stock and stock options of Bison Trails. Bison Trails is a platform-as-a-service company that provides a suite of easy-to-use blockchain infrastructure products and services on multiple networks to custodians, exchanges and funds. Prior to the acquisition, the Company held a minority ownership stake in Bison Trails, which was accounted for as a cost method investment. In accordance with ASC 805, Business Combinations , the acquisition was accounted for as a business combination achieved in stages under the acquisition method. Accordingly, the cost method investment was remeasured to fair value as of the acquisition date. The Company considered multiple factors in determining the fair value of the previously held cost method investment, including the price negotiated with the selling shareholders and current trading multiples for comparable companies. Based on this analysis, the Company recognized an $8.8 million gain on remeasurement, which was recorded in other expense (income), net in the condensed consolidated statement of operations on the acquisition date. The purchase consideration was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date with the excess recorded as goodwill, none of which is expected to be deductible for tax purposes. The final allocation of purchase consideration to assets and liabilities remains in process as the Company continues to evaluate certain balances, estimates, and assumptions during the measurement period (up to one year from the acquisition date). Any changes in the fair value of the assets acquired and liabilities assumed during the measurement period may result in adjustments to goodwill. The total preliminary consideration transferred in the acquisition was $457.3 million, consisting of the following (in thousands): Common stock of the Company $ 389,314 Previously held interest on acquisition date 10,863 Cash 28,726 Replacement of Bison Trails options 28,365 Total purchase consideration $ 457,268 Included in the purchase consideration are 496,434 shares of the Company’s Class A common stock that are subject to an indemnity holdback. These shares will be released 18 months after the closing date of the transaction. The results of operations and the provisional fair values of the assets acquired and liabilities assumed have been included in the condensed consolidated financial statements as of the date of acquisition. The following table summarizes the estimated fair values of assets acquired and liabilities assumed using a cost based approach (in thousands): Cash and cash equivalents $ 12,201 Crypto assets held 5,177 Accounts and loans receivable, net of allowance 2,323 Prepaid expenses and other current assets 122 Intangible assets 39,100 Goodwill 404,167 Other non-current assets 1,221 Lease right-of-use assets 808 Total assets 465,119 Accounts payable and accrued expenses 2,446 Lease liabilities 808 Other liabilities 4,597 Total liabilities 7,851 Net assets acquired $ 457,268 The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of acquisition (in thousands, except for years data): Fair Value Useful Life at Acquisition (in years) Developed technology $ 36,000 3 In-process research and development ("IPR&D") 1,200 N/A User base 1,900 3 The intangible assets will be amortized on a straight-line basis over their respective useful lives to Technology and development expenses for developed technology and General and administrative expenses for user base. Amortization of the IPR&D will be recognized in Technology and development expenses once the research and development is placed into service as internally developed software. Management applied significant judgement in determining the fair value of intangible assets, which involved the use of estimates and assumptions with respect to development costs and profit, costs to recreate customer relationships, market participation profit, and opportunity cost. Total acquisition costs of $3.7 million were incurred related to the acquisition, which were recognized as an expense and included in General and administrative expenses in the condensed consolidated statements of operations. Other Acquisitions During the nine months ended September 30, 2021, the Company also completed three other acquisitions that were not material individually, but were material when aggregated. In each of these acquisitions the Company acquired all issued and outstanding common stock and stock options of the acquiree. The total purchase consideration in each acquisition was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition dates, with the excess recorded as goodwill. For each acquisition, the final allocation of purchase consideration to assets and liabilities remains in process as the Company continues to evaluate certain balances, estimates, and assumptions during the measurement period (up to one year from each acquisition’s respective acquisition date). Any changes in the fair value of the assets acquired and liabilities assumed during the measurement period may result in adjustments to goodwill. The aggregate total preliminary consideration transferred in these acquisitions was $135.7 million, consisting of the following (in thousands): Common stock of the Company - issued $ 51,760 Common stock of the Company - to be issued 39,940 Cash 27,795 Cash payable 412 Contingent consideration arrangement 15,752 Aggregate total purchase consideration $ 135,659 The aggregate purchase consideration includes 160,840 shares of the Company’s Class A common stock to be issued six months after the respective acquisition date. The fair value of these shares on the acquisition date is included in Additional paid-in capital. Additionally, 39,663 shares of the Company’s Class A common stock included in the aggregate purchase consideration that were issued, or to be issued, are subject to an indemnity holdback. These shares will be released between 15 and 18 months after the closing date of each transaction. Also included in the aggregate purchase consideration is the original estimated fair value of the contingent consideration arrangement agreed to in one of the acquisitions. The contingent consideration consists of two separate tranches. The first tranche is settled one year after the closing date and may result in delivery of up to 75,534 shares of the Company’s Class A common stock if specified revenue targets are met during the first year after the closing date. The second tranche is settled two years after the closing date and may result in delivery of up to another 75,534 shares of the Company’s Class A common stock if specified revenue targets are met during only the second year after the closing date. For each tranche, the revenue targets are adjusted for changes in the combined Bitcoin (“BTC”) and Ethereum (“ETH”) market capitalization since the closing date. The total number of the Company’s Class A common stock issued to settle the contingent consideration arrangement would be adjusted downward in proportion to recognized revenues that do not meet the specified revenue targets. The contingent consideration arrangement is included in Other non-current liabilities and subject to subsequent measurement at fair value with changes in fair value recognized through Other expense (income), net. The results of operations and the provisional fair values of the assets acquired and liabilities assumed have been included in the condensed consolidated financial statements as of the dates of acquisition. The following table summarizes the aggregate estimated fair values of assets acquired and liabilities assumed using a cost based approach (in thousands): Cash and cash equivalents $ 4,915 Accounts receivable, net of allowance 57 Prepaid expenses and other current assets 209 Intangible assets 46,100 Goodwill 86,041 Total assets 137,322 Accounts payable and accrued expenses 281 Other liabilities 1,382 Total liabilities 1,663 Net assets acquired $ 135,659 The excess of aggregate purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill of $86.0 million, of which $77.1 million is expected to be deductible for US tax purposes based on the preliminary values. The goodwill balance is primarily attributed to the assembled workforce, market presence, synergies, and the use of purchased technology to develop future products and technologies. The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the dates of acquisition (in thousands, except for years data): Fair Value Useful Life at Acquisition (in years) Developed technology 33,700 2.7 User Base 1,000 2.5 In process research and development 1,600 N/A Customer relationships 9,800 5 The intangible assets will be amortized on a straight-line basis over their respective useful lives to Technology and development expenses for developed technology and General and administrative expenses for customer relationships and user base. Amortization of the IPR&D will be recognized in Technology and development expenses once the research and development is placed into service as internally developed software. Management applied significant judgement in determining the fair value of intangible assets, which involved the use of estimates and assumptions with respect to development costs and profit, costs to recreate customer relationships, market participation profit, and opportunity cost. These valuations incorporate significant unobservable inputs classified as Level 3. Total acquisition costs of $3.5 million were incurred related to these other acquisitions, which were recognized as expenses and included in General and administrative expenses in the condensed consolidated statements of operations. The Company also entered into employment agreements with key employees of the acquirees, which included stock-based compensation arrangements. In conjunction with these agreements, the Company recognized $3.2 million of compensation expenses on the acquisition dates included in Technology and development expenses. Stock-based compensation arrangements offered to these key employees with vesting conditions will be recognized as compensation expense in future periods. See Note 14. Stock-Based Compensation , for additional details regarding stock-based compensation issued to employees. Tagomi On July 31, 2020, the Company completed the acquisition of Tagomi Holdings, Inc. (“Tagomi”), by acquiring all issued and outstanding shares of common stock and stock options of Tagomi. Tagomi is an institutional brokerage for crypto assets and offers an end-to-end brokerage solution that caters to sophisticated traders and institutions. Tagomi operates an advanced trading platform which pools liquidity from multiple venues to offer efficient pricing, algorithmic trading, a suite of prime services (including delayed settlement and borrowing and lending of fiat currency and crypto assets), and a flexible account hierarchy and operational processes that meet the needs of institutional clients. The total consideration transferred in the acquisition was $41.8 million, consisting of the following (in thousands): Common stock of the Company $ 30,589 Replacement of Tagomi options and warrants 760 Cash 1,906 Settlement of pre-existing receivable 8,537 Total purchase consideration $ 41,792 The following table summarizes the fair values of assets acquired and liabilities assumed as of the date of acquisition (in thousands): Cash and cash equivalents $ 13,777 Customer custodial funds 19,837 Crypto assets held 5,687 Accounts and loans receivable, net of allowance 5,795 Prepaid expenses and other current assets 633 Intangible assets 7,350 Goodwill 22,516 Other non-current assets 1,611 Total assets 77,206 Custodial funds due to customers 20,787 Accounts payable and accrued expenses 5,953 Crypto borrowings 8,674 Total liabilities 35,414 Net assets acquired $ 41,792 The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill of $22.5 million, which is not deductible for tax purposes. The goodwill balance is primarily attributed to the market presence, synergies, and the use of purchased technology to develop future products and technologies. The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of acquisition (in thousands, except for years data): Fair Value Useful Life at Acquisition (in years) Developed technology $ 6,600 3 Customer relationships 400 5 Licenses 350 Indefinite The developed technology, customer relationships, and licenses represent the estimated fair value of Tagomi’s trading platform, existing relationships with customers, and money transmitter licenses held, respectively. Total acquisition costs of $1.1 million were incurred related to the acquisition, which were recognized as an expense and included in General and administrative expenses in the condensed consolidated statements of operations. A related party of the Company was a prior equity holder of Tagomi, and as a result of the acquisition, was entitled to receive up to 264,527 shares of the Company’s Class A common stock.

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Revenue recognition The Company determines revenue recognition from contracts with customers through the following steps: • identification of the contract, or contracts, with the customer; • identification of the performance obligations in the contract; • determination of the transaction price; • allocation of the transaction price to the performance obligations in the contract; and • recognition of the revenue when, or as, the Company satisfies a performance obligation. Revenue is recognized when control of the promised goods or services is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company primarily generates revenue through transaction fees charged on the platform. The following table presents revenue of the Company disaggregated by revenue source (in thousands): Three Months Ended Nine Months Ended 2021 2020 2021 2020 Net revenue Transaction revenue Retail, net $ 1,021,967 $ 262,624 $ 4,305,088 $ 588,451 Institutional, net 67,689 13,280 255,529 31,308 Total transaction revenue 1,089,656 275,904 4,560,617 619,759 Subscription and services revenue Blockchain rewards 81,490 3,246 131,056 7,408 Custodial fee revenue 31,468 4,803 86,616 10,594 Earn campaign revenue 15,172 1,531 43,230 1,640 Interest income 8,389 536 18,190 3,285 Other subscription and services revenue 8,561 643 25,018 1,390 Total subscription and services revenue 145,080 10,759 304,110 24,317 Total net revenue 1,234,736 286,663 4,864,727 644,076 Other revenue Crypto asset sales revenue 76,742 28,403 475,065 45,961 Corporate interest and other income 430 291 1,189 2,332 Total other revenue 77,172 28,694 476,254 48,293 Total revenue $ 1,311,908 $ 315,357 $ 5,340,981 $ 692,369 Transaction revenue Retail transaction revenue represents transaction fees earned from customers that are primarily individuals, while institutional transaction revenue represents transaction fees earned from institutional customers, such as hedge funds, family offices, principal trading firms, and financial institutions on the institutional platform. The Company’s service is comprised of a single performance obligation to provide a crypto asset matching service when customers buy, sell, or convert crypto assets on the platform. That is, the Company is an agent in transactions between customers and presents revenue for the fees earned on a net basis. Judgment is required in determining whether the Company is the principal or the agent in transactions between customers. The Company evaluates the presentation of revenue on a gross or net basis based on whether it controls the crypto asset provided before it is transferred to the customer (gross) or whether it acts as an agent by arranging for other customers on the platform to provide the crypto asset to the customer (net). The Company does not control the crypto asset being provided before it is transferred to the buyer, does not have inventory risk related to the crypto asset, and is not responsible for the fulfillment of the crypto asset. The Company also does not set the price for the crypto asset as the price is a market rate established by the platform. As a result, the Company acts as an agent in facilitating the ability for a customer to purchase crypto assets from another customer. The Company considers its performance obligation satisfied, and recognizes revenue, at the point in time the transaction is processed. Contracts with customers are usually open-ended and can be terminated by either party without a termination penalty. Therefore, contracts are defined at the transaction level and do not extend beyond the service already provided. The Company charges a fee at the transaction level. The transaction price, represented by the trading fee, is calculated based on volume and varies depending on payment type and the value of the transaction. Crypto asset purchase or sale transactions executed by a customer on the Company’s platform is based on tiered pricing that is driven primarily by transaction volume processed for a specific historical period. The Company has concluded that this volume-based pricing approach does not constitute a future material right since the discount is within a range typically offered to a class of customers with similar volume. The transaction fee is collected from the customer at the time the transaction is executed. In certain instances, the transaction fee can be collected in crypto assets, with revenue measured based on the amount of crypto assets received and the fair value of the crypto assets at the time of the transaction. The transaction price includes estimates for reductions in revenue from transaction fee reversals that may not be recovered from customers. Such reversals occur when the customer disputes a transaction processed on their credit card or their bank account for a variety of reasons and seeks to have the charge reversed after the Company has processed the transaction. These amounts are estimated based upon the most likely amount of consideration to which the Company will be entitled. All estimates are based on historical experience and the Company’s best judgment at the time to the extent it is probable that a significant reversal of revenue recognized will not occur. All estimates of variable consideration are reassessed periodically. The total transaction price is allocated to the single performance obligation. While the Company recognizes transaction fee reversals as a reduction of net revenue, crypto asset losses related to those same transaction reversals are included in Transaction expense. Blockchain rewards The Company generates revenues in crypto assets through various blockchain protocols. These blockchain protocols, or the participants that form the protocol networks, reward users for performing various activities on the blockchain, such as participating in proof-of-stake networks and other consensus algorithms. The Company considers itself the principal in transactions with the blockchain networks, and therefore presents such blockchain rewards earned on a gross basis. Blockchain rewards are primarily comprised of Staking revenue in which the Company participates in networks with proof-of-stake consensus algorithms, through creating or validating blocks on the network. In exchange for participating in the consensus mechanism of these networks, the Company earns rewards in the form of the native token of the network. Each block creation or validation is a performance obligation. Revenue is recognized at the point when the block creation or validation is complete and the rewards are transferred into a digital wallet that the Company controls. Revenue is measured based on the number of tokens received and the fair value of the token at contract inception. Custodial fee revenue The Company provides a dedicated secure cold storage solution to customers and earns a fee, which is based on a contractual percentage of the daily value of assets under custody. The fee is collected on a monthly basis. These contracts typically have one performance obligation which is provided and satisfied over the term of the contracts as customers simultaneously receive and consume the benefits of the services. The contract may be terminated by a customer at any time, without incurring a penalty. Customers are billed on the last day of the month during which services were provided, with the amounts being due within thirty days of receipt of the invoice. Amounts receivable from customers for custodial fee revenue, net of allowance, were $18.5 million and $4.4 million as of September 30, 2021 and December 31, 2020, respectively. The allowance recognized against these fees was not material for any of the periods presented. Earn campaign revenue The Company provides a platform for crypto asset issuers, the customer, to engage with the Company’s retail users and teach them about new crypto assets through the use of educational tools, videos, and tutorials. In exchange for completing a task, such as watching the video or downloading an application, retail users may be eligible to receive crypto assets from the crypto asset issuer. The Company is the agent with respect to the delivery of the crypto assets. The Company earns a commission from the crypto asset issuer based on the amount of crypto assets that are distributed to users. Interest income and corporate interest and other income The Company holds customer custodial funds and cash and cash equivalents at certain third-party banks which earn interest. The Company also earns interest income under a revenue sharing arrangement and on loans granted to retail and institutional users. Interest income is calculated using the interest method and is not within the scope of Topic 606 – Revenue from Contracts with Customers. Interest earned on customer custodial funds, revenue sharing, and loans is included in interest income within subscription and services revenue. Interest earned on cash and cash equivalents is included in corporate interest and other income, within other revenue. Other subscription and services revenue Other subscription and services revenue primarily includes revenue from Coinbase Cloud, which includes staking application and infrastructure services, as well as revenue from subscription licenses. Generally, these contracts with customers contain one performance obligation, may have variable and non-cash consideration, and are satisfied at a point in time or over the period that services are provided. Other revenue Other revenue includes the sale of crypto assets and corporate interest and other income. Periodically, as an accommodation to customers, the Company may fulfill customer transactions using the Company’s own crypto assets held for operating purposes. The Company has custody and control of the crypto assets prior to the sale to the customer and records revenue at the point in time when the sale to the customer is processed. Accordingly, the Company records the total value of the sale in other revenue and the cost of the crypto assets in Other operating expense, net within the condensed consolidated statements of operations. The cost of crypto assets used in fulfilling customer transactions was $68.6 million and $27.4 million for the three months ended September 30, 2021 and September 30, 2020, respectively, and $433.8 million and $45.5 million for the nine months ended September 30, 2021 and September 30, 2020, respectively.

Amortization expense of intangible assets was $4.3 million and $12.2 million for the three and nine months ended September 30, 2020, respectively. The Company estimates that there is no significant residual value related to its amortizing intangible assets. Crypto assets held are accounted for as an indefinite-lived intangible asset. Thus, unless they are designated as hedged items in fair value hedges, crypto assets are recognized at cost and subject to impairment losses if the fair value of crypto assets decreases below the carrying value at any time during the period. Impairment losses cannot be recovered for any subsequent increase in fair value until the sale or disposal of the asset. The Company recorded gross impairment charges of $58.4 million and $234.0 million during the three and nine months ended September 30, 2021 due to the observed market price of crypto assets decreasing below the carrying value at some point during the period. The Company partially recovered impairments recorded during the period through both subsequent crypto asset sales and disposals. Impairment charges of $75.7 million and $8.4 million relate to the crypto assets still held as of September 30, 2021 and September 30, 2020, respectively. Impairment expense is included in Other operating expense, net in the condensed consolidated statements of operations. Crypto assets borrowed that have been designated as hedged items in fair value hedges are initially measured at cost. Subsequent changes in fair value attributable to the hedged risk are adjusted to the carrying amount of these crypto assets, with changes in fair value recorded in Other operating expense, net in the condensed consolidated statements of operations. See Note 10. Derivatives , for additional details regarding crypto assets designated as hedged items in fair value hedges.

Debt Disclosure [Abstract]
INDEBTEDNESS	INDEBTEDNESS Convertible Senior Notes In May 2021, the Company issued an aggregate principal amount of $1.44 billion of convertible senior notes due in 2026 (the “2026 Convertible Notes”) pursuant to an indenture, dated May 18, 2021 (the “Convertible Notes Indenture”), between the Company and U.S. Bank National Association, as trustee. The 2026 Convertible Notes were offered and sold in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2026 Convertible Notes are senior unsecured obligations of the Company and bear interest at a rate of 0.5% per year payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2021. The 2026 Convertible Notes mature on June 1, 2026, unless earlier converted, redeemed or repurchased. The proceeds received of $1.42 billion were net of a 1% original issue discount. The initial conversion rate and conversion rate as of September 30, 2021 for the 2026 Convertible Notes is 2.6994 shares of the Company's Class A common stock per $1,000 principal amount of 2026 Convertible Notes, which is equivalent to an initial conversion price of approximately $370.45 per share of the Class A common stock. The conversion rate and conversion price are subject to customary adjustments under certain circumstances in accordance with the terms of the Convertible Notes Indenture. The 2026 Convertible Notes will be convertible at the option of the holders before December 1, 2025 only upon the occurrence of certain events, and from and after December 1, 2025, at any time at their election until the close of business on the second scheduled trading day immediately preceding June 1, 2026, only under certain circumstances. Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as applicable, cash, shares of the Company’s Class A common stock or a combination of cash and shares of the Company’s Class A common stock, at the Company’s election, based on the applicable conversion rate. In addition, if certain corporate events that constitute a make-whole fundamental change (as defined in the Convertible Notes Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time. Additionally in the event of a corporate event constituting a fundamental change (as defined in the Convertible Notes Indenture), holders of the 2026 Convertible Notes may require the Company to repurchase all or a portion of their 2026 Convertible Notes at a repurchase price equal to 100% of the principal amount of the 2026 Convertible Notes being repurchased, plus accrued and unpaid special interest or additional interest, if any, to, but excluding, the date of the fundamental change repurchase. The Company accounted for the 2026 Convertible Notes wholly as debt because (1) the conversion features do not require bifurcation as a derivative under ASC 815 and (2) the 2026 Convertible Notes were not issued at a substantial premium. Discounts on the 2026 Convertible Notes reflect a 1% original issue discount of $14.4 million and debt issuance costs related to the 2026 Convertible Notes of $19.4 million, which include commissions payable to the initial purchasers and third-party offering costs. Discounts are amortized to interest expense using the effective interest method over the contractual term of the 2026 Convertible Notes. Interest expense is included in Other expense (income), net in the condensed consolidated statements of operations. For the three months ended September 30, 2021, total interest expense on the 2026 Convertible Notes was $3.6 million with coupon interest expense of $1.9 million and the amortization of debt discounts and debt issuance costs of $1.7 million. For the nine months ended September 30, 2021, total interest expense on the 2026 Convertible Notes was $5.1 million with coupon interest expense of $2.7 million and the amortization of debt discounts and debt issuance costs of $2.4 million.The effective interest rate on the 2026 Convertible Notes is 0.98%. As of September 30, 2021, the outstanding aggregate principal balance of the 2026 Convertible Notes and the related unamortized discounts were $1.44 billion and $31.4 million, respectively. Capped Calls On May 18, 2021, in connection with the pricing of the 2026 Convertible Notes, the Company entered into privately negotiated capped call transactions (the “Capped Calls”) with certain financial institutions (the "option counterparties") at a cost of $90.1 million. The Capped Calls cover, subject to customary adjustments, the number of shares of Class A common stock initially underlying the 2026 Convertible Notes. By entering into the Capped Calls, the Company expects to reduce the potential dilution to its Class A common stock (or, in the event a conversion of the 2026 Convertible Notes is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion of the 2026 Convertible Notes its common stock price exceeds the conversion price of the 2026 Convertible Notes. The Capped Calls have an initial strike price of approximately $370.45 per share of Class A common stock and an initial cap price of approximately $478.00 per share of Class A common stock. The Capped Calls meet the criteria for classification in equity, are not remeasured each reporting period and are included as a reduction to Additional paid-in capital within stockholders’ equity. Senior Notes In September 2021, the Company completed the issuance of an aggregate principal amount of $1.0 billion of Senior Notes due on October 1, 2028 (the “2028 Senior Notes”) and an aggregate principal amount of $1.0 billion of Senior Notes due on October 1, 2031 (the “2031 Senior Notes” and together with the 2028 Senior Notes, the “Senior Notes”). The Senior Notes were issued within the United States only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act, and outside the United States to non-U.S. persons pursuant to Regulation S under the Securities Act. The Company issued the Senior Notes at par and paid approximately $24.0 million in total debt issuance costs, which includes commissions payable to the initial purchasers and third-party offering costs. Interest on the Senior Notes is payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 2022 at 3.375% per annum for the 2028 Senior Notes and 3.625% per annum for the 2031 Notes. The entire principal amount of the Senior Notes is due at the time of maturity, unless repurchased or redeemed at an earlier date. The Senior Notes were issued pursuant to an indenture, dated September 17, 2021 (the “Senior Notes Indenture”), among the Company, the Guarantor (as defined below) and the U.S. Bank National Association, as trustee. The Senior Notes are redeemable at the Company’s discretion, in whole or in part, at any time. If redeemed prior to October 1, 2024 for the 2028 Senior Notes and October 1, 2026 for the 2031 Senior Notes, the redemption price is subject to a make-whole premium calculated by reference to then-current U.S. Treasury rates plus a fixed spread, plus any accrued and unpaid interest. If redeemed on or after those respective dates, the make-whole premium does not apply. In addition, prior to October 1, 2024, the Company may redeem up to 40% of the aggregate principal amount of both Senior Notes with net cash proceeds from certain equity offerings at a redemption price equal to 103.375% of the principal amount of the 2028 Senior Notes to be redeemed and 103.625% of the principal amount of the 2031 Senior Notes to be redeemed, in each case, plus any accrued and unpaid interest. Upon the occurrence of a change of control triggering event (as defined in the Senior Notes Indenture), the Company must offer to repurchase each series of Senior Notes at a repurchase price equal to 101% of the principal amount of the Senior Notes to be repurchased, plus any accrued and unpaid interest, to, but excluding, the applicable repurchase date. The Senior Notes are guaranteed by one of the Company’s domestic subsidiaries, Coinbase, Inc. (the “Guarantor”) . Further, the indenture governing the Senior Notes contain customary covenants that restrict the ability of the Company and certain of its subsidiaries to incur debt and incur liens. The Company was in compliance with all covenants as of September 30, 2021. Discounts to the Senior Notes are amortized to interest expense using the effective interest method over the contractual terms of the respective note. For the three and nine months ended September 30, 2021, total interest expense on the 2028 Senior Notes was $1.4 million with coupon interest expense of $1.3 million and the amortization of debt discounts and debt issuance costs of $0.1 million. For the three and nine months ended September 30, 2021, total interest expense on the 2031 Senior Notes was $1.4 million with coupon interest expense of $1.4 million and the amortization of debt discounts and debt issuance costs of less than $0.1 million. The 2028 Senior Notes have an effective interest rate of 3.57% and the 2031 Senior Notes have an effective interest rate of 3.77%. As of September 30, 2021, the outstanding aggregate principal balance of the 2028 Senior Notes and the related unamortized discounts were $1.0 billion and $11.9 million, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES The Company’s crypto asset borrowings are accounted for as hybrid instruments, with a liability host contract that contains an embedded derivative based on the changes in the fair value of the underlying crypto asset. The host contract is not accounted for as a debt instrument because it is not a financial liability. The embedded derivative is accounted for at fair value, with changes in fair value recognized in Other operating expense, net in the condensed consolidated statements of operations. The liability host contracts and embedded derivatives are included in crypto asset borrowings in the condensed consolidated balance sheets. For risk management purposes, the Company applies hedge accounting using the embedded derivatives in qualifying fair value hedges to primarily hedge the fair value exposure of crypto asset prices. For qualifying fair value hedges, the changes in the fair value of the derivative and the fair value of the hedged item, the crypto assets, are recognized in current-period earnings in Other operating expense, net in the condensed consolidated statements of operations. Derivative amounts affecting earnings are recognized in the same line item as the earnings effect of the hedged item. The Company also entered into a warrant to purchase crypto assets from the respective crypto asset issuer. This contract was accounted for as a derivative at fair value, with changes in fair value recognized in Other operating expense, net in the consolidated statements of operations. The warrant was included in Prepaid expenses and other current assets in the consolidated balance sheets.

The estimated fair value of the contingent consideration arrangement was determined using the Monte Carlo simulation method and applying a risk-adjusted discount rate to the expected payoff on each of the settlement dates. The expected payoff was determined by forecasting revenues for the acquired entity and simulating changes to the price of our Class A common stock, as well as BTC and ETH market capitalization, using a risk-neutral Geometric Brownian Motion path. The simulations also utilized the estimated volatility of and correlation between these variables. The fair value is based on significant inputs not observable in the market and as such, incorporates Level 3 inputs. The following significant unobservable inputs were used: Three Months Ended September 30, 2021 Nine Month Ended September 30, 2021 Discount rate 30.0 % 30.0 % Volatility of forecasted revenues 146.1 % 146.1 % Assets and liabilities measured and recorded at fair value on a non-recurring basis The Company’s non-financial assets, such as goodwill, intangible assets, property and equipment, and crypto assets held but not designated in hedging relationships are adjusted to fair value when an impairment charge is recognized. Such fair value measurements are based predominately on Level 3 inputs. Fair value of crypto assets held are predominantly based on Level 2 inputs. Financial assets and liabilities not measured and recorded at fair value The Company’s financial instruments, including cash, restricted cash, certain customer custodial funds, USDC, and custodial funds due to customers are classified as Level 1 and carried at amortized cost, which approximates their fair value. The loans receivable are classified as Level 3 and are carried at amortized cost, which approximates their fair value. The Company estimates the fair value of its 2026 Convertible Notes and Senior Notes based on quoted prices in markets that are not active, which is considered a Level 2 valuation input. As of September 30, 2021, the estimated fair value of the 2026 Convertible Notes and Senior Notes were $1.44 billion and $1.92 billion, respectively.

STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Stock plans The Company maintains four equity incentive plans: the 2013 Stock Plan (the “2013 Plan”), the 2019 Equity Incentive Plan (the “2019 Plan”), the 2021 Equity Incentive Plan (the “2021 Plan”), and the 2021 Employee Stock Purchase Plan (the “ESPP,” and collectively, the “Plans”). Following the Direct Listing, the Company has only issued awards under the 2021 Plan and the ESPP, and no additional awards will be granted under the 2013 Plan and 2019 Plan. In April 2021, the Company adopted the 2021 Plan. The 2021 Plan serves as the successor to the 2019 Plan. Outstanding awards under the 2019 Plan continue to be subject to the terms and conditions of the 2019 Plan. The 2021 Plan provides for the granting of incentive stock options, restricted stock units (“RSUs”), restricted stock, stock appreciation rights and performance and stock bonus awards to assist in attracting, retaining and motivating employees. As of September 30, 2021, the Company has reserved 36,888,000 shares of Class A common stock for issuance under the 2021 Plan. The number of shares available for grant and issuance under the 2021 Plan will be automatically increased on January 1st of each of the first ten As of September 30, 2021, only stock options and RSUs were issued and outstanding under the Plans. Stock options Activity of options outstanding are as follows (in thousands, except per share and years data): Options Outstanding Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value Balance at January 1, 2021 63,256 $ 14.84 8.17 $ 2,527,396 Assumed options from acquisition 470 3.45 Exercised (22,272) 8.41 Forfeited and cancelled (1,308) 19.54 Balance at September 30, 2021 40,146 18.13 8.01 8,404,654 Vested and exercisable at September 30, 2021 16,228 13.91 7.24 3,465,888 Vested and expected to vest at September 30, 2021 34,012 17.17 7.86 7,153,199 As of September 30, 2021, there was total unrecognized compensation cost of $204.9 million related to unvested stock options. These costs are expected to be recognized over a weighted-average period of approximately 2.97 years. As of September 30, 2021, there were 568,973 shares subject to repurchase related to stock options early exercised and not yet vested, but that are expected to vest. As of September 30, 2021, the Company recorded a liability related to these shares subject to repurchase in the amount of $10.4 million, which is included within other current liabilities in the accompanying condensed consolidated balance sheets. Chief Executive Officer performance award During April 2021, as a result of the Company’s registration statement being declared effective by the Securities and Exchange Commission under the Securities Act, the performance condition of the option award granted to the Chief Executive Officer was met. On July 8, 2021, the first price target of the award was met, resulting in the vesting of 3,159,930 shares subject to the option award. During the three and nine months ended September 30, 2021, compensation expense of $22.2 million and $28.5 million was recognized related to this award, respectively. Restricted stock units The Company’s RSUs vest upon the satisfaction of a service-based condition. In general, the RSUs vest over a service period ranging from one Activity of RSUs outstanding under the Plan are as follows (in thousands, except per share data): Number of shares Weighted- Balance at January 1, 2021 3,766 $ 54.80 Granted 6,026 229.53 Vested (1,291) 220.63 Forfeited and cancelled (242) 202.03 Balance at September 30, 2021 8,259 152.05 For RSUs granted prior to the Direct Listing, the fair value of the Class A common stock was determined using linear interpolation between the dates at which the Company obtained third-party valuations, for financial reporting purposes. This method was determined to be reasonable, as no single event was identified that caused the increase in the fair value of the common stock. For RSUs granted after the Direct Listing of the Company’s Class A common stock, the closing stock price on the grant date of the Company’s Class A common stock was used as the fair value. As of September 30, 2021, there was total unrecognized compensation cost of $1.1 billion related to unvested RSUs. These costs are expected to be recognized over a weighted-average period of approximately 2.55 years. Restricted common stock As part of the Company’s acquisitions, the Company issued restricted Class A common stock. Vesting of this restricted Class A common stock is dependent on a service-based vesting condition that is satisfied over three years. The Company has the right to repurchase shares at par value for which the vesting condition is not satisfied. Activity of restricted Class A common stock are as follows (in thousands, except per share data): Number of shares Weighted- Balance at January 1, 2021 824 $ 23.46 Granted 1,416 177.15 Vested (275) 23.46 Forfeited and cancelled — — Balance at September 30, 2021 1,965 134.20 As of September 30, 2021, there was total unrecognized compensation cost of $217.7 million related to unvested restricted Class A common stock. These costs are expected to be recognized over a weighted-average period of approximately 2.36 years. Employee Stock Purchase Plan In February 2021, the Board approved and adopted the ESPP. The ESPP allows eligible employees the option to purchase shares of the Company's Class A common stock at a 15% discount, over a series of offering periods through accumulated payroll deductions over the period. The ESPP also includes a look-back provision for the purchase price if the stock price on the purchase date is lower than the stock price on the offering date. The Company recognizes stock-based compensation expenses related to shares issued pursuant to its ESPP on a straight-line basis over the offering period, which is 24 months. The fair value of employee stock purchase plan rights are estimated on the date of grant using the Black-Scholes-Merton option valuation model. The ESPP went effective on the day the Company’s registration statement went effective, April 1, 2021. The grant date of the initial offering period was May 3, 2021, and that offering period shall end on April 30, 2023. For the three and nine months ended September 30, 2021, total compensation expense of $3.1 million and $5.2 million was recognized related to the ESPP, respectively. As of September 30, 2021, the Company recorded a liability of $11.5 million related to the accumulated payroll deductions, which are refundable to employees who withdraw from the plan. This amount is included within Accounts payable and accrued expenses in the accompanying condensed consolidated balance sheets.

The ETR of (49.9)% for the three months ended September 30, 2021 was lower than the U.S. statutory rate of 21.0% due to (i) the tax effect of compensation expense on deductible stock option exercises at a fair market value, (ii) U.S. federal and California state research and development credits, offset by (i) the tax effect of non-deductible officer compensation, (ii) accrual for U.S. state taxes, (iii) the tax effect of non-deductible stock-based compensation, and (iv) non-deductible costs related to the Direct Listing capitalized for tax. The ETR for the nine months ended September 30, 2021 and September 30, 2020 was (30.3)% and 17.5%, respectively. The ETR of (30.3)% for the nine months ended September 30, 2021 was lower than the U.S. statutory rate of 21.0% due to (i) the tax effect of compensation expense on deductible stock option exercises at a fair market value, and (ii) U.S. federal and California state research and development credits, offset by (i) the tax effect of non-deductible officer compensation, (ii) accrual for U.S. state taxes, (iii) the tax effect of non-deductible stock-based compensation, and (iv) non-deductible costs related to the Direct Listing capitalized for tax.

These participating securities do not contractually require the holders of such shares to participate in the Company’s losses. The rights, including the liquidation and dividend rights, of the holders of Class A common stock and Class B common stock are identical, except with respect to voting. As the liquidation and dividend rights are identical for Class A common stock and Class B common stock, the undistributed earnings are allocated on a proportionate basis and the resulting income (loss) per share will, therefore, be the same for both Class A common stock and Class B common stock on an individual or combined basis.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Crypto asset wallets The Company has committed to securely store all crypto assets it holds on behalf of users. As such, the Company may be liable to its users for losses arising from theft or loss of user private keys. The Company has no reason to believe it will incur any expense associated with such potential liability because (i) it has no known or historical experience of claims to use as a basis of measurement, (ii) it accounts for and continually verifies the amount of crypto assets within its control, and (iii) it has established security around custodial private keys to minimize the risk of theft or loss. Since the risk of loss is remote, the Company had not recorded a liability at September 30, 2021 or December 31, 2020. Indemnifications In the event any registrable securities are included in a registration statement, the Company’s Amended and Restated Investors’ Rights Agreement (the “IRA”) entered into with certain of the Company’s holders of convertible preferred stock provides indemnity to each stockholder, their partners, members, officers, directors, and stockholders, legal counsel, and accountants; each underwriter, if any; and each person who controls each stockholder or underwriter, against any damages incurred in connection with investigating or defending any claim or proceeding arising as a result of such registration from which damages may result. The Company will reimburse each such party for any legal and any other expenses reasonably incurred, provided that the Company will not be liable in any such case to the extent the damages arise out of or are based upon any actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such stockholder or underwriter and stated to be specifically for use therein. The Company also has indemnity agreements with certain officers and directors of the Company pursuant to which the Company must indemnify the officer or director against all expenses, judgments, fines, and amounts paid in settlement reasonably incurred in connection with a third party proceeding, if the indemnitee acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Company, and in the case of a criminal proceeding, had no reasonable cause to believe the indemnitee’s conduct was unlawful. It is not possible to determine the maximum potential exposure under these indemnification agreements: (i) because the facts and circumstances involved in each claim are unique and we cannot predict the number or nature of claims that may be made; (ii) due to the unique facts and circumstances involved in each particular agreement; and (iii) due to the requirement for a registration of the Company’s securities before any of the indemnification obligations contemplated in the IRA become effective. The Company has also provided indemnities or similar commitments on standard commercial terms in the ordinary course of business. Legal proceedings The Company is subject to various litigation, regulatory investigations, and other legal proceedings that arise in the ordinary course of its business. The Company is also subject to regulatory oversight by numerous regulatory and other governmental agencies. The Company reviews its lawsuits, regulatory investigations, and other legal proceedings on an ongoing basis and provides disclosure and records loss contingencies in accordance with the loss contingencies accounting guidance. In accordance with such guidance, the Company establishes accruals for such matters when potential losses become probable and can be reasonably estimated. If the Company determines that a loss is reasonably possible and the loss or range of loss can be estimated, the Company discloses the possible loss in the condensed consolidated financial statements. In July 2021, a purported securities class action captioned Ramsey v. Coinbase Global, Inc., et al. , Case No. 3:21-cv-05634, was filed in the U.S. District Court for the Northern District of California against the Company, its directors, certain of its officers and employees, and certain venture capital and investment firms. The Complaint alleges violations of Sections 11, 12(a)(2) and 15 of the Securities Act of 1933, as amended, in connection with the Registration Statement and Prospectus filed in connection with the Direct Listing. In August 2021, two additional purported securities class actions captioned Klein v. Coinbase Global Inc. et al. , Case No. 3:21-cv-0604 and Catterlin v. Coinbase Global Inc. et al. , Case No. 3:21-cv-06149, were filed in the U.S. District Court for the Northern District of California, alleging similar claims and seeking the same relief. We dispute the claims in these cases and intend to vigorously defend against them. Based on the preliminary nature of the proceedings in these cases, the outcome of these matters remain uncertain. The Company believes the ultimate resolution of existing legal and regulatory investigation matters will not have a material adverse effect on the financial condition, results of operations, or cash flows of the Company. However, in light of the uncertainties inherent in these matters, it is possible that the ultimate resolution of one or more of these matters may have a material adverse effect on the Company’s results of operations for a particular period, and future changes in circumstances or additional information could result in additional accruals or resolution in excess of established accruals, which could adversely affect the Company’s results of operations, potentially materially. Tax regulation Current promulgated tax rules related to crypto assets are unclear and require significant judgments to be made in interpretation of the law, including but not limited to the areas of income tax, information reporting and the withholding of tax at source. Additional legislation or guidance may be issued by U.S. and non-U.S. governing bodies that may differ significantly from the Company's practices or interpretation of the law, which could have unforeseen effects on our financial condition and results of operations, and accordingly, the related impact on our financial condition and results of operations is not estimable.

Accounting Policies [Abstract]
Basis of presentation and principles of consolidation	Basis of presentation and principles of consolidation The accompanying interim condensed consolidated financial statements of the Company are unaudited. These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), on the same basis as the audited consolidated financial statements, and in management’s opinion, reflect all adjustments, consisting only of normal, recurring adjustments, that are necessary for the fair statement of the Company’s condensed consolidated balance sheet as of September 30, 2021, condensed consolidated results of operations for the three and nine months ended September 30, 2021 and September 30, 2020, and condensed consolidated statements of cash flows for the nine months ended September 30, 2021 and September 30, 2020. The unaudited condensed consolidated results of operations for the three and nine months ended September 30, 2021 and September 30, 2020 are not necessarily indicative of the results to be expected for the full year or any other period. These 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 filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on April 14, 2021 (the “Prospectus”). These accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. The Company’s subsidiaries are entities in which the Company holds, directly or indirectly, more than 50% of the voting rights or where it exercises control. Certain subsidiaries of the Company have a basis of presentation different from GAAP. For the purposes of these unaudited condensed consolidated financial statements, the basis of presentation of such subsidiaries is converted to GAAP. All intercompany accounts and transactions have been eliminated in consolidation. There were no changes to the significant accounting policies or recent accounting pronouncements that were disclosed in Note 2. Summary of Significant Accounting Policies
Reclassifications	Reclassifications Certain prior period amounts have been reclassified in order to conform with the current period presentation. These reclassifications have no impact on the Company’s previously reported consolidated net income.
Use of estimates	Use of estimates The preparation of the condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions in the Company’s condensed consolidated financial statements and notes thereto. Significant estimates and assumptions include the determination of the recognition, measurement, and valuation of current and deferred income taxes; the fair value of stock-based awards issued; the useful lives of intangible assets; the useful lives of property and equipment; the impairment of long-lived assets; the Company’s incremental borrowing rate; the fair value of assets acquired and liabilities assumed in business combinations, including contingent consideration arrangements; the fair value of derivatives and related hedges; the fair value of long-term debt; and loss provisions. Actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties. To the extent that there are material differences between these estimates and actual results, the Company’s condensed consolidated financial statements will be affected. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the result of which forms the basis for making judgments about the carrying values of assets and liabilities.
Business combinations	Business combinations The results of businesses acquired in a business combination are included in the Company’s condensed consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Acquisition-related costs incurred by the Company are recognized as an expense in General and administrative expenses within the condensed consolidated statements of operations. The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, and to the extent that the value was not previously finalized, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially recorded in connection with a business combination as of the acquisition date. The Company continues to collect information about facts and circumstance that existed at the date of acquisition and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill, provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statements of operations.
Accounts and loans receivable and allowance for doubtful accounts	Accounts and loans receivable and allowance for doubtful accounts Accounts and loans receivables are contractual rights to receive cash either on demand or on fixed or determinable dates, and are recognized as an asset on the Company’s balance sheet. Accounts and loans receivable consists of in-transit customer receivables, post-trade credit receivables, custodial fee revenue receivable, loans receivable, interest receivable, and other receivables. In-transit customer receivables represent settlements from third-party payment processors and banks for customer transactions. In-transit receivables are typically received within one or two business days of the transaction date. The Company establishes withdrawal-based limits in order to mitigate potential losses by preventing customers from withdrawing the crypto asset to an external blockchain address until the payment settles. In certain jurisdictions, in-transit customer receivables qualify as eligible liquid assets to meet regulatory requirements to fulfill the Company’s direct obligations under custodial funds due to customers. Post-trade credit receivables represent funds due for crypto assets delivered to credit eligible customers and are typically received within three business days from the transaction date. Post-trade credit receivables enable customers to instantly invest in crypto assets without pre-funding their trade. Custodial fee revenue receivable represents the fee earned and receivable by the Company for providing a dedicated secure cold storage solution to customers. The fee is based on a contractual percentage of the daily value of assets under custody and is collected on a monthly basis. Such custodial fee revenue income is included in the net revenue in the condensed consolidated statements of operations. Loans receivable represent loans made to retail users and institutions. These loans are collateralized with crypto assets held by those users in their crypto asset wallet on the Company’s platform. Loans receivable are subsequently measured at amortized cost. The Company recognizes an allowance for doubtful accounts for receivables based on expected credit losses. In determining expected credit losses, the Company considers historical loss experience, the aging of its receivable balance, and the fair value of any collateral held. For loans receivable, the Company applies the collateral maintenance provision practical expedient. The Company would recognize credit losses on these loans if there is a collateral shortfall and it is not reasonably expected that the borrower will replenish such a shortfall.
Concentration of credit risk	Concentration of credit risk The Company’s cash, cash equivalents, restricted cash, customer custodial funds, and accounts and loans receivable are potentially subject to concentration of credit risk. Cash, cash equivalents, restricted cash, and customer custodial funds are placed with financial institutions which are of high credit quality. The Company invests cash, cash equivalents, and customer accounts primarily in highly liquid, highly rated instruments which are uninsured. The Company may also have deposit balances with financial institutions which exceed the Federal Deposit Insurance Corporation insurance limit of $250,000. The Company also holds cash at crypto trading venues and performs a regular assessment of these crypto trading venues as part of its risk management process. The Company held $92.1 million and $48.9 million of USD Coin (“USDC”) as of September 30, 2021 and December 31, 2020, respectively. The underlying U.S. dollar denominated assets are recognized by the issuer in U.S. regulated financial institutions on behalf of USDC holders.
Recent accounting pronouncements	Recent accounting pronouncements Recently adopted accounting pronouncements On August 5, 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40) (“ASU 2020-06”). ASU 2020-06 simplifies accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity, by removing certain separation models that require the separation of a convertible debt instrument into a debt component and an equity or derivative component. ASU 2020-06 removes from U.S. GAAP the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. After adoption of ASU 2020-06 entities will not separately present in equity an embedded conversion feature in such debt. Instead entities will account for a convertible debt instrument wholly as debt, and for convertible preferred stock wholly as preferred stock (i.e., as a single unit of account), unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC 815 or (2) a convertible instrument was issued at a substantial premium. ASU 2020-06 also expands disclosure requirements for convertible instruments and simplifies areas of the guidance for diluted earnings-per-share calculations that are impacted by the amendments. Under ASU 2020-06, entities must apply the more dilutive of the if-converted method and the two-class method to all convertible instruments; the treasury stock method is no longer available. ASU 2020-06 eliminates an entity’s ability to overcome the presumption of share settlement, and as a result, the issuers of convertible debt that may be settled in any combination of cash or stock at the issuer’s option, must use the more dilutive among the if-converted method and the two-class method in computing diluted net income per share, which is typically more dilutive than the net share settlement under the treasury stock method. ASU 2020-06 is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted. The Company early adopted ASU 2020-06 on January 1, 2021. The adoption of this new guidance did not have an impact on the Company’s consolidated financial statements since the Company had no existing convertible notes prior to issuance of the 2026 Convertible Notes, described below, in the second quarter of 2021. Further, the Company’s outstanding convertible preferred stock, which were converted into common stock in conjunction with the Company’s direct listing of its Class A common stock on the Nasdaq Global Select Market (the “Direct Listing”), did not contain any beneficial conversion feature. The Company’s 2026 Convertible Notes are accounted for in accordance with this new guidance. See Note 9. Indebtedness for additional information. On December 18, 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes: Simplifying the Accounting for Income Taxes , as part of its overall simplification initiative to reduce the costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements. Among other things, the new guidance simplifies intraperiod tax allocation and reduces the complexity in accounting for income taxes with year-to-date losses in interim periods. The Company adopted the standard on January 1, 2021. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements. On August 29, 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40)—Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which aligns the accounting for implementation costs incurred in a hosting arrangement that is a service contract with the accounting for implementation costs incurred to develop or obtain internal-use software under Accounting Standards Codification (“ASC”) 350-40, in order to determine which costs to capitalize and recognize as an asset and which costs to expense. The Company adopted the standard on January 1, 2021 using the prospective transition approach. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements. On June 16, 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 replaces the “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. For available-for-sale debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. It also simplifies the accounting model for purchased credit-impaired debt securities and loans. The Company adopted the standard on January 1, 2021 using the modified retrospective approach. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements, as the Company’s receivables are either fully collateralized or are short term in nature and therefore less susceptible to risks and uncertainty of credit losses over extended periods of time.
Revenue recognition	Revenue recognition The Company determines revenue recognition from contracts with customers through the following steps: • identification of the contract, or contracts, with the customer; • identification of the performance obligations in the contract; • determination of the transaction price; • allocation of the transaction price to the performance obligations in the contract; and • recognition of the revenue when, or as, the Company satisfies a performance obligation. Revenue is recognized when control of the promised goods or services is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company primarily generates revenue through transaction fees charged on the platform. Transaction revenue Retail transaction revenue represents transaction fees earned from customers that are primarily individuals, while institutional transaction revenue represents transaction fees earned from institutional customers, such as hedge funds, family offices, principal trading firms, and financial institutions on the institutional platform. The Company’s service is comprised of a single performance obligation to provide a crypto asset matching service when customers buy, sell, or convert crypto assets on the platform. That is, the Company is an agent in transactions between customers and presents revenue for the fees earned on a net basis. Judgment is required in determining whether the Company is the principal or the agent in transactions between customers. The Company evaluates the presentation of revenue on a gross or net basis based on whether it controls the crypto asset provided before it is transferred to the customer (gross) or whether it acts as an agent by arranging for other customers on the platform to provide the crypto asset to the customer (net). The Company does not control the crypto asset being provided before it is transferred to the buyer, does not have inventory risk related to the crypto asset, and is not responsible for the fulfillment of the crypto asset. The Company also does not set the price for the crypto asset as the price is a market rate established by the platform. As a result, the Company acts as an agent in facilitating the ability for a customer to purchase crypto assets from another customer. The Company considers its performance obligation satisfied, and recognizes revenue, at the point in time the transaction is processed. Contracts with customers are usually open-ended and can be terminated by either party without a termination penalty. Therefore, contracts are defined at the transaction level and do not extend beyond the service already provided. The Company charges a fee at the transaction level. The transaction price, represented by the trading fee, is calculated based on volume and varies depending on payment type and the value of the transaction. Crypto asset purchase or sale transactions executed by a customer on the Company’s platform is based on tiered pricing that is driven primarily by transaction volume processed for a specific historical period. The Company has concluded that this volume-based pricing approach does not constitute a future material right since the discount is within a range typically offered to a class of customers with similar volume. The transaction fee is collected from the customer at the time the transaction is executed. In certain instances, the transaction fee can be collected in crypto assets, with revenue measured based on the amount of crypto assets received and the fair value of the crypto assets at the time of the transaction. The transaction price includes estimates for reductions in revenue from transaction fee reversals that may not be recovered from customers. Such reversals occur when the customer disputes a transaction processed on their credit card or their bank account for a variety of reasons and seeks to have the charge reversed after the Company has processed the transaction. These amounts are estimated based upon the most likely amount of consideration to which the Company will be entitled. All estimates are based on historical experience and the Company’s best judgment at the time to the extent it is probable that a significant reversal of revenue recognized will not occur. All estimates of variable consideration are reassessed periodically. The total transaction price is allocated to the single performance obligation. While the Company recognizes transaction fee reversals as a reduction of net revenue, crypto asset losses related to those same transaction reversals are included in Transaction expense. Blockchain rewards The Company generates revenues in crypto assets through various blockchain protocols. These blockchain protocols, or the participants that form the protocol networks, reward users for performing various activities on the blockchain, such as participating in proof-of-stake networks and other consensus algorithms. The Company considers itself the principal in transactions with the blockchain networks, and therefore presents such blockchain rewards earned on a gross basis. Blockchain rewards are primarily comprised of Staking revenue in which the Company participates in networks with proof-of-stake consensus algorithms, through creating or validating blocks on the network. In exchange for participating in the consensus mechanism of these networks, the Company earns rewards in the form of the native token of the network. Each block creation or validation is a performance obligation. Revenue is recognized at the point when the block creation or validation is complete and the rewards are transferred into a digital wallet that the Company controls. Revenue is measured based on the number of tokens received and the fair value of the token at contract inception. Custodial fee revenue Earn campaign revenue The Company provides a platform for crypto asset issuers, the customer, to engage with the Company’s retail users and teach them about new crypto assets through the use of educational tools, videos, and tutorials. In exchange for completing a task, such as watching the video or downloading an application, retail users may be eligible to receive crypto assets from the crypto asset issuer. The Company is the agent with respect to the delivery of the crypto assets. The Company earns a commission from the crypto asset issuer based on the amount of crypto assets that are distributed to users. Interest income and corporate interest and other income The Company holds customer custodial funds and cash and cash equivalents at certain third-party banks which earn interest. The Company also earns interest income under a revenue sharing arrangement and on loans granted to retail and institutional users. Interest income is calculated using the interest method and is not within the scope of Topic 606 – Revenue from Contracts with Customers. Interest earned on customer custodial funds, revenue sharing, and loans is included in interest income within subscription and services revenue. Interest earned on cash and cash equivalents is included in corporate interest and other income, within other revenue. Other subscription and services revenue Other subscription and services revenue primarily includes revenue from Coinbase Cloud, which includes staking application and infrastructure services, as well as revenue from subscription licenses. Generally, these contracts with customers contain one performance obligation, may have variable and non-cash consideration, and are satisfied at a point in time or over the period that services are provided.
Loans receivable	Loans receivableThe Company’s credit exposure is significantly limited and no allowance was recorded against these loans receivable. Loans receivable are measured at amortized cost.
