Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Forge Global Holdings, Inc. (the “Company” , and f/k/a Motive Capital Corp) is a financial services platform headquartered in San Francisco, California. The Company has built a trusted marketplace to serve the unique needs of the private market by making purchases and sales of equity in private companies simple, transparent, and highly efficient to scale. The Company has strategically invested in technology to provide individual and institutional participants an efficient and liquid market, access to a large number of private company investment opportunities and the information and transparency they need to make well informed investment decisions. By digitizing a historically analog, complex and opaque process, the Company’s platform delivers opportunities to trade in private company stocks. Today, the Company is a leading provider of mission-critical infrastructure technology and services for the private market. On March 21, 2022 (the “Closing Date”), the Company consummated the Business Combination (as defined below) pursuant to the terms of the Agreement and Plan of Merger dated September 13, 2021 (the "Merger Agreement"), by and among Motive Capital Corp, a blank check company incorporated as a Cayman Islands exempted company in 2020 (“MOTV”), FGI Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of MOTV (“Merger Sub”), and Forge Global, Inc., a Delaware corporation (“Legacy Forge”). Pursuant to the Merger Agreement, on the Closing Date, immediately prior to the consummation of the Business Combination, MOTV changed its jurisdiction of incorporation from the Cayman Islands to the State of Delaware and changed its corporate name to "Forge Global Holdings, Inc." (the “Domestication”). On the Closing Date, Merger Sub merged with and into Legacy Forge (the "Merger"), with Legacy Forge surviving the Merger as a direct, wholly-owned subsidiary of the Company (together with the Merger, the Domestication, and the other transactions contemplated by the Merger Agreement, the “Business Combination”). The Merger was accounted for as a reverse recapitalization with Legacy Forge being the accounting acquirer and MOTV as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the unaudited condensed consolidated financial statements represents the accounts of Legacy Forge and its wholly owned subsidiaries as if Legacy Forge is the predecessor to the Company. The shares and net loss per common share prior to the Merger have been retroactively restated as shares reflecting the exchange ratio (the "Exchange Ratio") as established by the Merger Agreement (each outstanding share of Legacy Forge Class A common stock was exchanged for approximately 3.122931 shares of the Company’s common stock, including all shares of Legacy Forge preferred stock, which were converted to shares of Legacy Forge's Class A common stock immediately prior to the Merger). Prior to the Business Combination, MOTV’s units, public shares, and Public Warrants were listed on the New York Stock Exchange under the symbols “MOTV-UN”, “MOTV”, and “MOTV-WT”, respectively. On the Closing Date, the Company's common stock and Public Warrants began trading on The New York Stock Exchange (“NYSE”), under the symbols “FRGE” and “FRGE WS”, respectively. See Note 3, "Recapitalization" for additional details.

Summary of Accounting Policies

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, and its subsidiaries and have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. In the normal course of business, the Company has transactions with various investment entities as discussed in Note 9, "Off Balance Sheet Items." In certain instances, the Company provides investment advisory services to pooled investment vehicles (each, a “Fund”). The Company does not have discretion to make any investment, except for the specific investment for which a Fund was formed. The Company performs an assessment to determine (a) whether the Company’s investments or other interests will absorb portions of a variable interest entity’s expected losses or receive portions of the entity’s expected residual returns and (b) whether the Company’s involvement, through holding interests directly or indirectly in the entity would give it a controlling financial interest. The Company consolidates entities in which it, directly or indirectly, is determined to have a controlling financial interest. Consolidation conclusions are reviewed quarterly to identify whether any reconsideration events have occurred. There have been no changes to the Company's significant accounting policies described in the audited consolidated financial statements for the year ended December 31, 2021, that have had a material impact on these condensed consolidated financial statements and related notes. Unaudited Interim Condensed Consolidated Financial Information The accompanying interim condensed consolidated financial statements as of March 31, 2022 and for the three months ended March 31, 2022 and 2021 and accompanying notes, are unaudited. These unaudited interim condensed consolidated financial statements (the "condensed consolidated financial statements") have been prepared in accordance with GAAP applicable to interim financial statements. These financial statements are presented in accordance with the rules and regulations of the SEC and do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. As such, the information included herein should be read in conjunction with the consolidated financial statements and accompanying notes as of and for the year ended December 31, 2021 (the “audited consolidated financial statements”) that was included in the Company’s Form 8-K filed on March 25, 2022, which provides a more complete discussion of the Company’s accounting policies and certain other information. In management’s opinion, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements, which include only normal recurring adjustments, necessary for a fair statement of the Company’s financial position as of March 31, 2022 and its condensed consolidated results of operations and cash flows for the three months ended March 31, 2022 and 2021. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results expected for the year ending December 31, 2022 or any other future interim or annual periods. As a result of the Merger, prior period share and per share amounts presented in the accompanying condensed consolidated financial statements and these related notes have been retroactively converted. Segment Information The Company operates as a single operating segment and reportable segment. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, allocating resources and evaluating the Company’s financial performance. The Company operates primarily in the United States, and, accordingly, the geographic distribution of revenue and assets is not significant. For the three months ended March 31, 2022, revenue outside of the United States, based on customer billing address, was $2,931, and was not material for the three months ended March 31, 2021. As of March 31, 2022 and December 31, 2021, long-lived assets located outside of the United States were not material. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such management estimates include, but are not limited to collectability of accounts receivable, the fair value of financial assets and liabilities, the fair value of assets acquired and liabilities assumed in business combinations, the fair value of consideration paid for business combinations, the useful lives of acquired intangible assets and property and equipment, the impairment of long-lived assets and goodwill, the fair value of warrants, equity awards and share-based compensation expenses, including the determination of the fair value of the Company’s common stock prior to the Merger, and the valuation of deferred tax assets and uncertain tax positions. These estimates are inherently subjective in nature and, therefore, actual results may differ from the Company’s estimates and assumptions. The Company bases its estimates on historical experience and also on assumptions that it believes are reasonable. Further, the Company applies judgment in determining whether, directly or indirectly, it has a controlling financial interest in the Funds, in order to conclude whether any of the Funds must be consolidated. Starting in 2020, the global COVID-19 pandemic created disruption in global supply chains, increased rates of unemployment and adversely impacted many industries. In 2022, the COVID-19 pandemic continues to persist. We continue to closely monitor developments; however, we cannot predict the future impact of COVID-19 on our operational and financial performance, or the specific ways the pandemic may uniquely impact our customers, employees, and business partners, all of which continue to involve significant uncertainties that depend on future developments, which include, among others, the severity and duration of the pandemic and its impact on the overall economy and other industry sectors; vaccination rates; the longer-term efficacy of vaccinations; and the potential emergence of new, more transmissible or severe variants. The Company believes the estimates and assumptions underlying the condensed consolidated financial statements are reasonable and supportable based on the information available as of March 31, 2022. These estimates may change as new events occur and additional information is obtained, and related financial impacts will be recognized in the Company’s consolidated financial statements as soon as those events become known. Fair Value Measurements Fair value is defined as the exchange price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When developing fair value measurements, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurements. Three levels of inputs may be used to measure fair value: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Accounts Receivable, Net Accounts receivable consist of amounts billed and currently due from customers, which are subject to collection risk. The allowance for doubtful accounts is based on the Company’s assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for doubtful accounts based on a combination of factors, including an assessment of the customer’s aging balance, the financial condition of the customer, and the amount of any receivables in dispute. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. The total allowance for doubtful accounts netted against account receivables in the condensed consolidated balance sheets was $1,819 and $1,517 as of March 31, 2022 and December 31, 2021, respectively. Concentration of Credit Risks Financial instruments that potentially subject the Company to concentrations of credit risk primarily comprise of cash and cash equivalents and restricted cash, payment-dependent notes receivables, and accounts receivable. Cash and cash equivalents and restricted cash may, at times, exceed amounts insured by the Federal Deposit Insurance Corporation and the Securities Investor Protection Corporation, respectively. The Company’s exposure to credit risk in the event of default by financial institutions is limited to the amounts recorded on the condensed consolidated balance sheets. The Company performs periodic evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company has not experienced any losses on its deposits of cash and cash equivalents to date. The Company’s exposure to credit risk associated with its contracts with holders of private company equity (“sellers”) and investors (“buyers”) related to the transfer of private securities is measured on an individual counterparty basis. Concentrations of credit risk can be affected by changes in political, industry, or economic factors. To reduce the potential for risk concentration, the Company’s exposure is monitored in light of changing counterparty and market conditions. As of March 31, 2022 and December 31, 2021, the Company did not have any material concentrations of credit risk outside the ordinary course of business. As of March 31, 2022 and December 31, 2021, no customers accounted for more than 10% of the Company’s accounts receivable. No customer accounted for more than 10% of total revenue, less transaction-based expenses for the three months ended March 31, 2022 and 2021, respectively. Revenue Recognition The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company generates revenue from fees charged for the trading of private placements on its marketplace platform, and fees for account and asset management provided to customers. The Company disaggregates revenue by service type, as management believes that this level of disaggregation best depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are impacted by economic factors. Revenue from Contracts with Customers The Company enters into contracts with customers that can include various services, which are capable of being distinct and accounted for as separate performance obligations. When applicable, an allocation of the transaction fees to the performance obligations or to the distinct goods or services that form part of a single performance obligation will depend on the individual facts and circumstances of the contract. All of the Company’s revenues are from contracts with customers. The Company is the principal in its contracts, with the exception of sub-account fees, in which the Company acts as an agent and records revenue from fees earned related to cash balances in customers’ custodial accounts. Each of our significant performance obligations and our application of ASC 606 to our revenue arrangements are discussed in further detail below: Placement Fees — The Company maintains a trading platform which generates revenues by collecting transaction fees from institutions, individual investors and private equity holders. Placement fees are charged by the Company for meeting the point-in-time performance obligation of executing a private placement on its platform. Placement fee rates are individually negotiated for each transaction and vary depending on the specific facts and circumstance of each agreement. These fees are event-driven and invoiced upon the closing of the transaction outlined in each agreement. These fees may be expressed as a dollar amount per share, a flat dollar amount, or a percentage of the gross transaction proceeds. The Company earns agency placement fees in non-underwritten transactions, such as private placements of equity securities. The Company enters into arrangements with individual accredited customers or pooled investment vehicles to execute private placements in the secondary market. The Company will receive placement fees on these transactions and believes that its trade execution performance obligation is completed upon the placement and consummation of a transaction and, as such, revenue is earned on the transaction date with no further obligation to the customer at that time. The Company acts as a principal and recognizes the placement fee revenue earned for the execution of a trade on a gross basis. Custodial Administration Fees — The Company generates revenues primarily by performing custodial account administration and maintenance services for its customers. Specifically, the Company charges administration fees for its services in maintaining custodial accounts, including asset-based fees, which are determined by the number and types of assets in these accounts. Additionally, the Company earns fees for opening and terminating accounts, and facilitating transactions, which are assessed at the point of transaction. Account and asset fees are assessed on the first day of the calendar quarter. Cash administration fees are based on cash balances within the custodial accounts and are assessed on the last day of the month. Revenues from custodial administration fees are recognized either over time as underlying performance obligations are met and day-to-day maintenance activities are performed for custodial accounts, or at a point in time upon completion of transactions requested by custodial account holders. Contract Balances Contract assets represent amounts for which we have recognized revenue for contracts that have not yet been invoiced to our customers. The Company does not have any contract assets as of March 31, 2022 and December 31, 2021. Contract liabilities consist of deferred revenue, which relates to amounts invoiced in advance of performance under a revenue contract. The total contract liabilities of $230 and $357 as of March 31, 2022 and December 31, 2021, respectively, related to advance billings for placement fees and custodial administration fees, recorded in accrued expenses and other current liabilities on the condensed consolidated balance sheets. Practical Expedients In certain arrangements, the Company receives payment from a customer either before or after the performance obligation has been satisfied; however, the contracts do not contain a significant financing component. The Company has applied the practical expedient in ASC 606 and excludes information about a) remaining performance obligations that have an original expected duration of one year or less and b) transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. The Company has also applied the practical expedient in accordance with ASC 340-40, Other Assets and Deferred Costs to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. Transaction-Based Expenses Transaction-based expenses represent the fees incurred to support placement and custodial activities. These include expenses for fund insurance, fund management and fund settlement expenses that relates to services provided to the Funds, and external broker fees and transfer fees related to placement and custodial services provided to other brokerage and custodial customers to facilitate transactions. Warrant Liabilities The Public Warrants, Private Placement Warrants and the warrants issued in connection with the Merger (see Note 3 and 10) are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the carrying value of the instruments to fair value at each reporting period until they are exercised. The Company will continue to adjust the warrant liability for changes in the fair value until the earlier of a) the exercise or expiration of the warrants or b) the redemption of the warrants, at which time the warrants will be reclassified to additional paid-in-capital. Recent Accounting Pronouncements As an “emerging growth company,” the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election and no new accounting pronouncements were adopted during the period. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, with subsequent amendments, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires immediate recognition of management’s estimates of current expected credit losses. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2022, and interim periods within that fiscal year, with early adoption permitted. The Company is currently evaluating the impact of adoption on the consolidated financial statements.

Reverse Recapitalization [Abstract]
Recapitalization	Recapitalization As discussed in Note 1, “Organization and Description of Business”, on the Closing Date, Legacy Forge completed the acquisition of MOTV a nd acquired 100% of MOTV’s shares and Legacy Forge received gross proceeds of $215,613, which includes $7,865 in proceeds from MOTV's trust and bank accounts, net of redemptions, $68,500 in proceeds from the PIPE Investment (as defined below), of which $500 is recorded in accounts receivable in the condensed consolidated balance sheet as of March 31, 2022, and $140,000 in proceeds from the A&R FPA (as defined below). As of March 31, 2022, the Company recorded $61,806 of transaction costs, which consisted of legal, accounting, and other professional services directly related to the Merger, of which $58,673 was related to common stock issued during the Merger and was recorded as a reduction to additional paid-in capital. The remaining $3,132 was related to issuance of Public and Private Placement Warrants, including warrants issued to A&R FPA investors, and was expensed immediately upon consummation of the Merger as acquisition-related transaction cost in the condensed consolidated statements of operations and comprehensive (loss) income. The cash outflows related to these costs were presented as financing activities in the Company’s condensed consolidated statements of cash flows. These deferred offering costs are offset against proceeds upon accounting for the consummation of the Merger. In addition, upon closing of the Merger, certain executives received a one-time transaction bonus for an aggregate amount of $17,735, of which $12,218 was to be paid to the executives in cash, and the remaining amount $5,517 was offset against outstanding promissory notes that were due from these executives as of the Closing Date (see Note 10). The transaction bonus is included in compensation and benefits in the condensed consolidated statement of operations and comprehensive (loss) income for the three months ended March 31, 2022. On the Closing Date, each holder of MOTV Class A ordinary stock received one share of the Company’s common stock, par value $0.0001, for each MOTV Class A ordinary share held prior to the Merger, and each holder of MOTV Class B ordinary stock received one share of the Company’s common stock, par value $0.0001, for each MOTV Class B ordinary share held prior to the Merger. See Note 10, “Capitalization” and Note 11, “Warrants”, for additional details of the Company’s stockholders’ equity prior to and subsequent to the Merger. All equity awards of Legacy Forge were assumed by the Company and converted into comparable equity awards that are settled or exercisable for shares of the Company’s common stock. As a result, each outstanding stock option of Legacy Forge was converted into an option to purchase shares of the Company’s common stock based on the Exchange Ratio and each outstanding warrant of Legacy Forge was converted into a warrant to purchase shares of the Company’s common stock based on the Exchange Ratio. The Merger was accounted for as a reverse recapitalization with Legacy Forge as the accounting acquirer and MOTV as the acquired company for accounting purposes. Legacy Forge was determined to be the accounting acquirer since Legacy Forge's former management makes up the majority of the Company's management team, Legacy Forge’s former management nominated or represents a majority of the Company’s board of directors, and Legacy Forge represents the majority of the continuing operations of the Company. Accordingly, all historical financial information presented in these unaudited condensed consolidated financial statements represents the accounts of Legacy Forge and its wholly owned subsidiary. Net assets were stated at historical cost consistent with the treatment of the transaction as a reverse recapitalization of Legacy Forge. Each public and private warrant of MOTV that was unexercised at the time of the Merger was assumed by the Company and represents the right to purchase one share of the Company’s common stock upon exercise of such warrant. PIPE Investment On March 21, 2022, concurrently with the execution of the Merger Agreement, MOTV entered into subscription agreements with certain investors, to which such investors collectively subscribed for an aggregate of 6,850,000 shares of the Company’s common stock at $10.00 per share for aggregate gross proceeds of $68,500 (the “PIPE Investment”). The PIPE Investment was consummated concurrently with the closing of the Merger. Amended and Restated Forward Purchase Agreement

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value MeasurementsFinancial instruments consist of cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities, payment-dependent notes receivable, payment-dependent notes payable, and warrant liabilities. Cash equivalents, payment-dependent notes receivable, payment-dependent notes payable, and warrant liabilities are stated at fair value on a recurring basis. Restricted cash, accounts receivable, accounts payable, and accrued liabilities are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date. The Company did not have short-term investments as of March 31, 2022 and December 31, 2021. The following tables present the fair value hierarchy for assets and liabilities measured at fair value on a recurring basis: As of March 31, 2022 Level 1 Level 2 Level 3 Total Cash and cash equivalents: Money market funds $ 159,316 $ — $ — $ 159,316 Payment-dependent notes receivable, current 243 — — 243 Payment-dependent notes receivable, noncurrent — — 14,975 14,975 Total financial assets $ 159,559 $ — $ 14,975 $ 174,534 Payment-dependent notes payable, current 243 — — 243 Payment-dependent notes payable, noncurrent — — 14,975 14,975 Warrant liabilities — — 5,000 5,000 Public Warrants 30,654 — — 30,654 Private Placement Warrants — 12,262 — 12,262 Total financial liabilities $ 30,897 $ 12,262 $ 19,975 $ 63,134 As of December 31, 2021 Level 1 Level 2 Level 3 Total Cash and cash equivalents: Money market funds $ 24,240 $ — $ — $ 24,240 Payment-dependent notes receivable, current 1,153 — — 1,153 Payment-dependent notes receivable, noncurrent — — 13,453 13,453 Total financial assets $ 25,393 $ — $ 13,453 $ 38,846 Payment-dependent notes payable, current $ 1,153 $ — $ — $ 1,153 Payment-dependent notes payable, noncurrent — — 13,453 13,453 Warrant liabilities — — 7,844 7,844 Total financial liabilities $ 1,153 $ — $ 21,297 $ 22,450 The Company classifies money market funds and certain payment-dependent notes receivable and payment-dependent notes payable within Level 1 of the fair value hierarchy because the Company values these investments using quoted market prices. The Company classifies the Private Placement Warrants within Level 2, because they were valued using quoted prices of an identical instrument. The Company classifies certain payment-dependent notes receivable and payment-dependent notes payable within Level 3 of the fair value hierarchy if the underlying securities are equity of private companies whose regular financial and nonfinancial information is generally not available other than when it is publicly disclosed, or significant unobservable inputs are used to estimate fair value. The following tables summarize the quantitative inputs and assumptions used for the Company’s payment-dependent notes receivable and payment-dependent notes payable classified as Level 3 of the fair value hierarchy: As of March 31, 2022 Level 3 Measurements Fair Valuation Significant Range Financial assets Payment-dependent notes receivable $ 14,975 Transaction prices N/A(1) N/A Financial liabilities Payment-dependent notes payable $ 14,975 Transaction prices N/A(1) N/A As of December 31, 2021 Level 3 Measurements Fair Valuation Significant Range Financial assets Payment-dependent notes receivable $ 13,453 Transaction prices N/A(1) N/A Financial liabilities Payment-dependent notes payable $ 13,453 Transaction prices N/A(1) N/A (1) The Company considers completed transactions made through the Company’s platform for the relevant private securities as relevant data inputs. The Company uses a hybrid method that incorporates the Black-Scholes option-pricing model and an adjusted backsolve model to estimate the fair value of the warrant liabilities, other than Public and Private Placement Warrants. This approach is a scenario-based analysis that considers many assumptions, including the likelihood of potential liquidity events, the nature and timing of such potential events, actions taken with regard to the warrants at expiration, as well as discounts for lack of marketability of the underlying securities and warrants . Subsequent to the Merger, the Series B-1 preferred stock warrants and Junior preferred stock warrants were converted to common stock warrants. As a result, the Series B-1 preferred stock warrants were remeasured at fair value prior to the conversion resulting in a change in fair value of $106 recognized as a component o f change in fair value of warrant liabilities within the condensed consolidated statements of operations and comprehensive (loss) income, and then settled in additional paid-in capital as a result of the conversion to equity-classified common stock warrants. The Junior Preferred Warrants (as defined below, see Note 11) were remeasured at fair value prior to the conversion, which did not result in a change in fair value for the three months ended March 31, 2022. These warrants will remain liability-classified, as the Company has an obligation to issue a variable number of shares of common stock for a fixed monetary amount of $5,000. The Company estimated the fair value of the warrants' liability, other than Public and Private Placement Warrants, as of March 31, 2022 and December 31, 2021, respectively, using the following key assumptions: As of March 31, December 31, Fair value of underlying securities $ 33.9 $ 30.8 Discounts for lack of marketability 0.0% 0.0% Expected term (years) 3.6 3.4 – 8.8 Expected volatility 44.3% 40.4% – 44.3% Risk-free interest rate 2.4% 1.0% – 1.5% Expected dividend yield 0.0% 0.0% Fair value per warrant 23.2 $5.0 - $22.0 The Company performed calculation of the fair value of Junior Preferred Warrants as of March 31, 2022 based on the assumptions noted above, however the total warrant liability associated with the Junior Preferred Warrants has not changed, as the Company's obligation to issue a variable number of shares of common stock is limited to a maximum fixed fair value amount of $5,000. The Public Warrants were valued as of March 31, 2022 using the listed trading price of $1.66 per public warrant. The Company transfers financial instruments out of Level 3 on the date when underlying input parameters are readily observable from existing market quotes. Transfers from Level 3 to Level 1 generally relate to a company going public and listing on a national securities exchange. During the three months ended March 31, 2022 there were no transfers of securities into or out of Level 3. During the three months ended March 31, 2021, there were transfers of securities segregated for customers from Level 3 to Level 1, as one private company was acquired by a public company and became publicly-traded under the acquirer, and the Company was able to obtain independent market-quoted prices for the acquirer company. The following tables provide reconciliation for all financial assets measured at fair value using significant unobservable inputs (Level 3) for three months ended March 31, 2022 and 2021: Balance as of December 31, 2020 $ 51,859 Acquisition of short-term investments 362 Change in fair value of short-term investments (23) Short-term investments transferred out of Level 3 to Level 1 (339) Change in fair value of payment-dependent notes receivable 21,309 Settlement of payment-dependent notes receivable (261) Balance as of March 31, 2021 $ 72,907 Balance as of December 31, 2021 $ 13,453 Change in fair value of payment-dependent notes receivable 1,522 Balance as of March 31, 2022 $ 14,975 The following tables provide reconciliation for payment-dependent notes payable measured at fair value using significant unobservable inputs (Level 3) for three months ended March 31, 2022 and 2021: Balance as of December 31, 2020 $ 51,859 Change in fair value of payment-dependent notes payable 21,309 Settlement of payment-dependent notes payable (261) Balance as of March 31, 2021 $ 72,907 Balance as of December 31, 2021 $ 13,453 Change in fair value of payment-dependent notes payable 1,522 Balance as of March 31, 2022 $ 14,975 The following tables provide reconciliation for warrant liabilities measured at fair value using significant unobservable inputs (Level 3) for three months ended March 31, 2022 and 2021 : Balance as of December 31, 2020 $ 1,780 Change in fair value of warrant liabilities 908 Balance as of March 31, 2021 $ 2,688 Balance as of December 31, 2021 $ 7,844 Change in fair value of warrant liabilities 106 Settlement of the warrant liability via conversion to equity-classified common stock warrants (2,950) Balance as of March 31, 2022 $ 5,000

During the three months ended March 31, 2022, the Company ceased using one of its leased office spaces and made a decision to sublease this space to a third party. The sublease agreement was signed in April 2022. Based on the terms of the sublease agreement, the Company determined that the right-of-use asset related to this office space is impaired, and recorded an impairment loss of $265 for the three months ended March 31, 2022 in rent and occupancy in the condensed consolidated statement of operations and comprehensive (loss) income.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesThe Company is subject to claims and lawsuits in the ordinary course of business, including arbitration, class actions and other litigation, some of which include claims for substantial or unspecified damages. The Company is also the subject of inquiries, investigations, and proceedings by regulatory and other governmental agencies. The Company reviews its lawsuits, regulatory inquiries and other legal proceedings on an ongoing basis and provides disclosures and records loss contingencies in accordance with the loss contingencies accounting guidance. The Company establishes an accrual for losses at management’s best estimate when the Company assesses that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. If no amount within the range is considered a better estimate than any other amount, an accrual for losses is recorded based on the bottom amount of the range. Accrual for loss contingencies are recorded in accounts payable and accrued expenses and other current liabilities on the condensed consolidated balance sheets and expensed in general and administrative expenses in our condensed consolidated statements of operations and comprehensive (loss) income. The Company monitors these matters for developments that would affect the likelihood of a loss and the accrued amount, if any, and adjusts the amount as appropriate. Legal Proceeding On January 7, 2022, Erika McKiernan, in her capacity as Stockholder Representative for the former stockholders of of SharesPost , filed a lawsuit against the Company in the Court of Chancery of the State of Delaware, asserting claims in connection with the Agreement and Plan of Merger, dated as of May 10, 2020, by and among the Company, Sharespost, Thanksgiving Merger Sub, Inc., and Erika McKiernan as the Stockhoder Representative, as amended on November 6, 2020 (the "SharesPost Merger Agreement”). In general, the complaint asserts breaches of the SharesPost Merger Agreement and seeks declaratory judgements establishing those breaches The Company is unable to predict the outcome, nor the amount of time and expense that will be required to resolve this action. At this juncture, the Company does not believe this action will have a material adverse impact on its operations or financial position. The Company believes the allegations set forth in this action are without merit and intends to defend vigorously against the lawsuit. No provision for a loss contingency has been recorded as the amount of losses, if any, is not estimable as of March 31, 2022. 401(k) Plan The Company has established a tax-qualified retirement plan under Section 401(k) of the Internal Revenue Code for all of its U.S. employees, including executive officers, who satisfy certain eligibility requirements, including requirements relating to age and length of service. The Company matches 2% of every dollar contributed to the plan by employees, including executive officers, up to a maximum of $6. During the three months ended March 31, 2022 and 2021, the Company contributed $418 and $134, respectively, to the defined contribution plan.

Warrants [Abstract]
Warrants	Warrants Warrants to Purchase Series B-1 Preferred Stock or Subsequent Round Stock In May 2020, Legacy Forge entered into a Note and Warrant Purchase Agreement with investors pursuant to which it issued certain convertible notes(the “2020 Convertible Notes”). In connection with the issuance of the 2020 Convertible Notes, the note holders entered into a Note and Warrant Purchase Agreement for the options to purchase shares based on coverage of 5% of the 2020 Convertible Notes principal amounts (the “May 2020 Warrants”). The note holders can purchase either (i) the Series B-1 preferred stock of Legacy Forge at Series B-1 price of $3.9760 or (ii) any subsequent round stock of Legacy Forge at the subsequent round price. The warrants have a five-year contractual life and may be exercised at any time during that period. In October 2020, Legacy Forge entered into a Loan and Security Agreement (“2020 Loan and Security Agreement”) with another lending institution that provided for a term loan in the amount of $15,000. In October 2020, simultaneously with the 2020 Loan and Security Agreement, the lender entered into a Warrant to Purchase Shares of Preferred Stock Agreement with Legacy Forge for the options to purchase a coverage amount of $3,513 of shares (the “October 2020 Warrants”). The investors can purchase either the Series B-1 convertible preferred stock of Legacy Forge at Series B-1 price of $3.9760 or (ii) any subsequent round stock of Legacy Forge at the subsequent round price. The warrants have a ten-year contractual life and may be exercised at any time during that period. Prior to the Merger, the May 2020 Warrants and October 2020 Warrants were classified as liabilities in Legacy Forge's consolidated balance sheets. Legacy Forge remeasured the May 2020 Warrants and October 2020 Warrants at each balance sheet date to fair value (Note 4). Subsequent to the Merger, the May 2020 Warrants and October 2020 Warrants were converted to Legacy Forge's common stock warrants. As a result, the May 2020 Warrants and October 2020 Warrants were adjusted to fair value prior to conversion, and then settled in additional paid-in capital as a result of the conversion to equity-classified common stock warrants. The Company recorded changes in fair value of the May 2020 Warrants and October 2020 Warrants of $106 and $123 in change in fair value of warrant liabilities in the Company’s condensed consolidated statements of operations and comprehensive (loss) income during the three months ended March 31, 2022 and 2021, respectively. Warrants to Purchase Junior Preferred Stock In November 2020, in connection with the SharesPost acquisition, Legacy Forge issued a total of 3,122,931 warrants (“Junior Preferred Warrants”) to purchase shares of Legacy Forge's Junior Preferred Stock at an exercise price of $3.9760 per share, with a cap of extended value of $5,000. The Junior Preferred Warrants have a five-year contractual life and may be exercised at any time during that period. Prior to the Merger, the warrants were classified as a liability in the condensed consolidated balance sheets. The Company remeasures the warrants at each balance sheet date using a hybrid method (Note 4). Subsequent to the Merger, the Junior Preferred Warrants were converted to the Company's common stock warrants. As a result, the Junior Preferred Warrants were adjusted to fair value prior to conversion and remain classified as a liability, as the Company has an obligation to issue a variable number of shares of common stock for a fixed monetary amount of $5,000. The Company recorded changes in fair value of the Junior Preferred Warrants that were converted to warrants to purchase common stock of $0 and $785 change in fair value of warrant liabilities in the Company’s condensed consolidated statements of operations and comprehensive (loss) income during the three months ended March 31, 2022 and 2021, respectively. Public Warrants and Private Placement Warrants As the accounting acquirer, Legacy Forge is deemed to have assumed warrants for Class A common stock that were held by Motive Capital Funds Sponsor, LLC (the “Sponsor”) at an exercise price of $11.50 ("Private Placement Warrants"), 13,800,000 Class A common stock warrants held by MOTV's shareholders at an exercise price of $11.50 ("Public Warrants"), an d 4,666,664 Public Warrants at an exercise price of $11.50 that were issued in connection with the A&R FPA that was consummated upon the Closing Date. In accordance with the warrant agreement, warrants will become exercisable on April 21, 2022, subject to other terms of the warrant agreement, including but not limited to, the Company having an effective registration statement under the Securities Act covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to them is available. The warrants will expire in five years after the completion of the Business Combination, or earlier upon redemption or liquidation. Subsequent to the Merger, the Private Placement Warrants and Public Warrants for shares of common stock meet liability classification requirements since the warrants may be required to be settled in cash under a tender offer. In addition, Private Placement Warrants are potentially subject to a different settlement amount as a result of being held by the Sponsor which precludes the Private Placement Warrants from being considered indexed to the entity's own stock. Therefore, these warrants are classified as liabilities on the condensed consolidated balance sheets. As of March 31, 2022, no warrants have been exercised. As of March 31, 2022, the following warrants were outstanding (in thousands, except for share and per share amounts): Warrant Type Shares Exercise Price per Share Public 18,466,604 $ 11.50 Private 7,386,667 $ 11.50

Share-based Compensation	Share-Based Compensation Prior Stock Plan In March 2018, Legacy Forge adopted its 2018 Equity Incentive Plan, as amended from time to time, (“Amended 2018 Equity Incentive Plan” or “2018 Plan”), which provides for grants of share-based awards, including stock options and restricted stock awards (“RSAs”), and other forms of share-based awards. The 2018 Plan was terminated in March 2022 in connection with the adoption of the 2022 Stock Plan (the “2022 Plan”). Accordingly, no shares are available for future issuances under the 2018 Plan following the adoption of the 2022 Plan. 2022 Stock Plan In March 2022, prior to and in connection with the Merger, the Company adopted the 2022 Plan, which provides for grants of share-based awards, including stock options and restricted stock units (“RSUs”), and other forms of share-based awards. The Company has reserved 12,899,504 shares of common stock for the issuance of awards under the 2022 Plan. In addition, the number of shares of common stock reserved and available for issuance under the 2022 Plan will automatically increase on January 1 of each year for a period of ten years, beginning on January 1, 2023 and on each January 1 thereafter and ending on the tenth anniversary of the adoption date of the 2022 Plan, in an amount equal to (1) 3% of the outstanding number of shares of common stock of the Company on the preceding December 31, or (2) a lesser number of shares as approved by the Company's board of directors. 2022 Employee Stock Purchase Plan In March 2022, prior to and in connection with the Merger, the Company adopted the 2022 Employee Stock Purchase Plan (the “2022 ESPP”). The 2022 ESPP authorizes the issuance of 4,072,000 shares of common stock under purchase rights granted to the Company's employees or to employees of any of its designated affiliates. The number of shares of common stock reserved for issuance will automatically increase on January 1 of each year, beginning on January 1, 2023 and each January 1 thereafter until the 2022 ESPP terminates according to its terms, by the lesser of (i) 4,072,000 shares of common stock, or (ii) 1% of the outstanding number of shares of common stock on the immediately preceding December 31. The Company's board of directors may determine that such increase will be less than the amount set forth in (i) and (ii) above. Reserve for Issuance The Company has the following shares of common stock reserved for future issuance, on an as-if converted basis: March 31, December 31, Conversion of convertible preferred stock — 86,815,192 Warrants to purchase convertible preferred stock — 3,540,546 Warrants to purchase common stock 3,774,437 233,891 Shares available for grant under 2018 Plan — 1,133,920 Stock options issued and outstanding under 2018 Plan 14,960,960 15,712,433 Shares available for grant under 2022 Plan 12,899,504 — Stock options issued and outstanding under 2022 Plan — — Shares available for grant under 2022 ESPP 4,072,000 — Outstanding Private Placement Warrants 7,386,667 — Outstanding Public Warrants 18,466,604 — Total shares of common stock reserved 61,560,172 107,435,982 Stock options Stock options generally vest over four years and expire ten years from the date of grant. Vested stock options generally expire from three months to five years after termination of employment. Stock option activity during the three months ended March 31, 2022 consisted of the following: Stock Options Weighted Average Exercise Price Weighted- Averages Life (Years) Aggregate Intrinsic Value Balance as of December 31, 2021 5,031,310 $ 6.85 9.2 years $ 120,491 Retroactive application of recapitalization 10,681,124 $ (4.66) Balance as of December 31, 2021 15,712,434 $ 2.19 Exercised (194,977) $ 0.54 Cancelled/Forfeited/Expired (556,497) $ 0.63 Balance as of March 31, 2022 14,960,960 $ 2.27 8.7 years $ 472,858 Vested and exercisable as of March 31, 2022 4,549,923 $ 0.80 8.0 years $ 150,512 The weighted-average grant date fair value of stock options granted during the three months ended March 31, 2022 and 2021 were $0 and $2.35 per share, respectively. The intrinsic value of stock options exercised during the three months ended March 31, 2022 and 2021 was $5,901 and $17,510, respectively. The total grant date fair value of stock options vested during the three months ended March 31, 2022 and 2021 was $5,736 and $2,495, respectively. The Company recorded share-based compensation of $7,757 and $991 for the three months ended March 31, 2022 and 2021, respectively, related to stock options. In addition, for the three months ended March 31, 2022, the Company recognized stock-based compensation expense of $621 related to pre-close issuance common stock for services. Future share-based compensation for unvested stock options granted and outstanding as of March 31, 2022, is $18,892, which is to be recognized over a weighted-average period of 2.57 years . Performance and Market Condition Options In May 2021, Legacy Forge’s board of directors granted the Chief Executive Officer a performance and market condition-based option covering 3,122,931 shares of Legacy Forge's Class AA common stock with an exercise price of $3.9760 per share. The options are divided into three tranches of 1,040,976 options, 1,040,976 options and 1,040,979 options, corresponding to the three Aggregate Exit Proceeds Thresholds (as defined below). The awards vest only upon the satisfaction of (1) certain performance conditions, which is the occurrence of an IPO, merger with a SPAC, or a secondary sale for total proceeds of at least $250,000 and (2) market condition, which is holders of Legacy Forge's B-1 Preferred Stock having realized (i) aggregate exit proceeds with fair market value of at least $9.94, $14.91, and $19.88 per share (the “Share Price Thresholds”); and (ii) an aggregate interest rate compounded annually which, when used as the discount rate to calculate the net present value, with respect to the occurrence of an IPO, merger with a SPAC or acquisition, that is equal to or greater than 20.0%, 30.0% and 35.0% (the “IRR Thresholds”, and together with the Share Price Thresholds, the “Aggregate Exit Proceeds Thresholds”). In the event of an IPO or a merger with a SPAC, the Aggregate Exit Proceeds Thresholds are measured on the basis of the closing price average for any trailing 20 trading day period (the “Measurement Period”) that occurs following such IPO or a merger with a SPAC, with the Measurement Period commencing upon expiration of the 180-day lock-up period following such IPO or merger with a SPAC, until the options expire or the Chief Executive Officer ceases to provide services to the Company. The options expire within 10 years less one day following the grant date. Upon consummation of the Business Combination, the performance condition was met and the Company recorded cumulative catch-up compensation expense of $4,564 during the three months ended March 31, 2022. The Company used the Monte Carlo simulation model to determine the fair value of the options with performance and market-based vesting conditions for purposes of calculating share-based compensation expense if vesting conditions met. The Monte Carlo simulation model incorporates the probability of satisfying performance and market conditions and uses transaction details such as stock price, contractual terms, maturity and risk-free interest rates, as well as volatility. The fair value of the options with no performance or market vesting conditions is based on the market value of common stock on the date of grant. The fair value of the performance-based stock options was $2.27 per option share estimated using the Monte Carlo simulation methodology. The unrecognized compensation expense was $2,532 as of March 31, 2022. Early Exercised Options Under the 2018 Plan, certain stock option holders may have the right to exercise unvested options, subject to a repurchase right held by the Company at the original exercise price, in the event of voluntary or involuntary termination of employment of the option holders, until the options are fully vested. As of March 31, 2022 and December 31, 2021, the cash proceeds received for unvested shares of common stock recorded within accrued expenses and other current liabilities in the condensed consolidated balance sheets were $1,554 and $785 as of March 31, 2022 and December 31, 2021, respectively, which will be transferred to additional paid-in capital upon vesting. Nonrecourse Promissory Notes to Early Exercise Stock Options In the three months ended March 31, 2021, certain executive officers of the company exercised stock options early by executing promissory notes. The Company has accounted for the promissory notes as nonrecourse in their entirety since the promissory notes are not aligned with a corresponding percentage of the underlying shares. Such arrangements were accounted for as modifications to the original stock options to which they relate, as the maturity date of the promissory notes reflects the legal term of the stock option for purposes of valuing the award. During the three months ended March 31, 2022, there were no promissory notes issued upon early exercise of options. All outstanding promissory notes have been settled as of March 31, 2022. Options Granted to Directors In July 2021, Legacy Forge’s board of directors granted options to certain members of the board in connection with their services, to purchase 499,669 shares of Legacy Forge's Class AA common stock at exercise price of $5.43 per share. Subject to the option agreement, the options shall vest in full and become exercisable as of immediately prior to the consummation of a deemed liquidation event or SPAC transaction. The performance-based vesting condition for the options granted to certain board members was satisfied as of March 31, 2022 and the Company recorded $1,233 of share-based compensation expense related to the options granted to certain board members. The fair value has been estimated using the Black-Scholes pricing model with the following assumptions: Fair value of common stock $ 6.11 Expected term (years) 5.3 Expected volatility 40.0% Risk-free interest rate 0.7% Expected dividend yield 0.0% RSAs Certain RSAs were granted to the Company's executives in exchange for a consideration at a specified strike price and were further subject to vesting condition. To the extent unvested, the shares issued in respect of such RSAs remain subject to repurchase. As of March 31, 2022, and December 31, 2021, there were 520,489 and no shares that were subject to repurchase, respectively, with the aggregate exercise price of $135 and $0, respectively. The related common stock unvested liability is included in accrued expenses and other current liabilities on the condensed consolidated balance sheet. The Company recorded share-based compensation expense of $148 and $148 for the three months ended March 31, 2022 and 2021, respectively, related to RSAs. As of March 31, 2022, the total unrecognized expense related to all RSAs was $223, which the Company expects to recognize over a weighted-average period of 0.25 years

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss per Share Prior to the Merger and prior to effecting the recapitalization, the holders of Legacy Forge's Class AA, Class EE-1 and Class EE-2 common stock were entitled to the same right to participate in the Company’s gains or losses. Therefore, net loss per share is presented as a single class of common stock. Earnings per share calculations for all periods prior to the Merger have been retrospectively restated to the equivalent number of shares reflecting the Exchange Ratio established in the reverse capitalization. Subsequent to the Merger, the Company has one class of common stock. The diluted net loss per share attributable to common stockholders is calculated by giving effect to all potentially dilutive common stock equivalents during the period using the two-class method. The Company’s convertible notes, redeemable preferred stock, stock options, warrants, and early exercised stock options are considered to be potential common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to common stockholders because the holders of these securities do not have a contractual right to share in the Company's losses, and their effect would be antidilutive. Therefore, the net loss for the three months ended March 31, 2022 was attributed to common stockholders only. The following table sets forth the computation of basic and diluted net (loss) income per share attributable to common stockholders for the periods presented: Three Months Ended March 31, 2022 2021 Numerator: Net (loss) income attributable to common stockholders, basic $ (64,424) $ 938 Less: undistributed earnings attributable to participating securities $ — $ (938) Net (loss) income attributable to common stockholders, diluted $ (64,424) $ — Denominator: Weighted-average number of shares used to compute net (loss) income per share attributable to common stockholders, basic 66,007,461 61,598,361 Dilutive effect of common share equivalents — 54,714,474 Weighted-average number of shares used to compute net (loss) income per share attributable to common stockholders, diluted 66,007,461 116,312,835 Net (loss) income per share attributed to common stockholders: Basic $ (0.98) $ 0.00 Diluted $ (0.98) $ 0.00 The following potentially dilutive shares were excluded in the calculation of diluted shares outstanding as the effect would have been anti-dilutive: Three Months Ended March 31, 2022 2021 Outstanding options 14,960,963 17,176 Common stock and preferred stock warrants 3,774,437 3,774,437 Public and Private Placement Warrants issued upon Merger 25,853,271 — Common stock subject to repurchase 3,018,878 — Convertible notes — 693,078 Total 47,607,549 4,484,691

Related Party Transactions	Off Balance Sheet Items The Company organizes a series of investment funds, each of which is represented by a limited liability company (“LLC”) within Forge Investments LLC and by portfolio companies within Forge Investments SPC and Forge Investments II SPC. The funds were formed for the purpose of investing in securities relating to a single private company. Each series of funds consists of a separate and distinct portfolio of investments owned by different investors. The Company utilizes third-party fund administrators to manage the funds and has no ownership interest nor participation in the gains or losses of the entities represented by the funds. The Company paid for the expenses incurred by these entities, including fund insurance expenses of $80 and $331, and fund management expenses of $21 and $30 for the three months ended March 31, 2022 and 2021, respectively, included in transaction-based expenses in condensed consolidated statements of operations and comprehensive (loss) income. Also, the Company paid fund audit fees of $315 and $461 during the three months ended March 31, 2022 and 2021, respectively, included in professional services in condensed consolidated statements of operations and comprehensive (loss) income. The Company did not consolidate Forge Investments LLC and Forge Investment SPC, or the investment funds, because the Company has no direct or indirect interest in Forge Investments LLC and Forge Investment SPC, or the investment funds, and the expenses that the Company pays on behalf of Forge Investments LLC and Forge Investment SPC, or the investment funds, are not significant to In October 2019, Legacy Forge issued convertible notes to investors, of which $2,400 was received from certain directors and employees of Legacy Forge. As of December 31, 2020, Legacy Forge had a $2,400 related party balance on convertible notes outstanding. The notes were fully repaid in January 2021. Legacy Forge entered into client engagement agreements with certain companies to serve as exclusive transaction agent to help facilitate private purchases of shares of issuers. These companies are identified as related parties who are holders of either Legacy Forge’s common stock or redeemable convertible preferred stock. The Company recognized $631 in placement fee revenue in the condensed consolidated statements of operations and comprehensive (loss) income for trade executed with the underlying LLCs and portfolio companies for the three months ended March 31, 2022. The associated revenue recognized for the three months ended March 31, 2021 is immaterial. The Company obtains insurance coverage from Munich Re, a shareholder of the Company, to indemnify Forge Investments for its contractual obligations to funds investors if shareholders fail to transfer ownership interests upon certain trigger events. During the three months ended March 31, 2022 and 2021, the Company incurred $80 and $331 in insurance premiums, respectively, and are included in transaction-based expenses in the condensed consolidated statements of operations and comprehensive (loss) income. Financial Technology Partners LP (“Financial Technology Partners”), a shareholder of the Company, serves as financial and strategic advisor to the Company on its financing, merger, and acquisition transactions. During the three months ended March 31, 2022, the Company incurred $18,283 in fees to Financial Technology Partners, of which $17,356 was related to common stock issued during the Merger and was recorded as a reduction to additional paid-in capital. The remaining $927 was related to issuance of Public and Private Placement Warrants, including warrants issued to A&R FPA investors, and was expensed immediately upon consummation of the Merger as acquisition-related transaction cost in the condensed consolidated statements of operations and comprehensive (loss) income. The Company leases one of its office spaces from the former owner of IRA Services. The former owner became a shareholder of the Company upon the acquisition of IRA Services which subsequently renamed as Forge Trust. IRA Services was a non-depository trust company authorized to act as a custodian of self-directed individual retirement accounts. The Company incurred $94 in rent to this shareholder during the three months ended March 31, 2022 and 2021, respectively, and are included in rent and occupancy in the condensed consolidated statements of operations and comprehensive (loss) income. James Herbert, II, one of the Company's directors, through the James and Cecillia Herbert 1994 Revocable Trust, purchased 75,000 shares of the Company's’s common stock (for a purchase price of $750) in the PIPE Investment, concurrently and in connection with the closing of the Business Combination. Mr. Herbert's transaction was on the same terms as the other investors who purchased shares in the PIPE Investment pursuant to certain subscription agreements dated September 13, 2021. Prior to the Business Combination, one of Legacy Forge's directors was also a director of Temasek Holding (Private) Limited ("Temasek"). Temasek, through its wholly-owned subsidiary, Ossa Investments Pte. Ltd, purchased 1,000,000 shares of the Company's’s common stock (for a purchase price of $10,000) in the PIPE Investment, concurrently and in connection with the closing of the Business Combination.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, and its subsidiaries and have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation.
Consolidation	In the normal course of business, the Company has transactions with various investment entities as discussed in Note 9, "Off Balance Sheet Items." In certain instances, the Company provides investment advisory services to pooled investment vehicles (each, a “Fund”). The Company does not have discretion to make any investment, except for the specific investment for which a Fund was formed. The Company performs an assessment to determine (a) whether the Company’s investments or other interests will absorb portions of a variable interest entity’s expected losses or receive portions of the entity’s expected residual returns and (b) whether the Company’s involvement, through holding interests directly or indirectly in the entity would give it a controlling financial interest. The Company consolidates entities in which it, directly or indirectly, is determined to have a controlling financial interest. Consolidation conclusions are reviewed quarterly to identify whether any reconsideration events have occurred. There have been no changes to the Company's significant accounting policies described in the audited consolidated financial statements for the year ended December 31, 2021, that have had a material impact on these condensed consolidated financial statements and related notes.
Segment Information	Segment Information The Company operates as a single operating segment and reportable segment. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, allocating resources and evaluating the Company’s financial performance.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such management estimates include, but are not limited to collectability of accounts receivable, the fair value of financial assets and liabilities, the fair value of assets acquired and liabilities assumed in business combinations, the fair value of consideration paid for business combinations, the useful lives of acquired intangible assets and property and equipment, the impairment of long-lived assets and goodwill, the fair value of warrants, equity awards and share-based compensation expenses, including the determination of the fair value of the Company’s common stock prior to the Merger, and the valuation of deferred tax assets and uncertain tax positions. These estimates are inherently subjective in nature and, therefore, actual results may differ from the Company’s estimates and assumptions. The Company bases its estimates on historical experience and also on assumptions that it believes are reasonable. Further, the Company applies judgment in determining whether, directly or indirectly, it has a controlling financial interest in the Funds, in order to conclude whether any of the Funds must be consolidated. Starting in 2020, the global COVID-19 pandemic created disruption in global supply chains, increased rates of unemployment and adversely impacted many industries. In 2022, the COVID-19 pandemic continues to persist. We continue to closely monitor developments; however, we cannot predict the future impact of COVID-19 on our operational and financial performance, or the specific ways the pandemic may uniquely impact our customers, employees, and business partners, all of which continue to involve significant uncertainties that depend on future developments, which include, among others, the severity and duration of the pandemic and its impact on the overall economy and other industry sectors; vaccination rates; the longer-term efficacy of vaccinations; and the potential emergence of new, more transmissible or severe variants. The Company believes the estimates and assumptions underlying the condensed consolidated financial statements are reasonable and supportable based on the information available as of March 31, 2022. These estimates may change as new events occur and additional information is obtained, and related financial impacts will be recognized in the Company’s consolidated financial statements as soon as those events become known.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the exchange price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When developing fair value measurements, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurements. Three levels of inputs may be used to measure fair value: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Accounts Receivable, Net	Accounts Receivable, NetAccounts receivable consist of amounts billed and currently due from customers, which are subject to collection risk. The allowance for doubtful accounts is based on the Company’s assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for doubtful accounts based on a combination of factors, including an assessment of the customer’s aging balance, the financial condition of the customer, and the amount of any receivables in dispute. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified.
Concentration of Credit Risks	Concentration of Credit Risks Financial instruments that potentially subject the Company to concentrations of credit risk primarily comprise of cash and cash equivalents and restricted cash, payment-dependent notes receivables, and accounts receivable. Cash and cash equivalents and restricted cash may, at times, exceed amounts insured by the Federal Deposit Insurance Corporation and the Securities Investor Protection Corporation, respectively. The Company’s exposure to credit risk in the event of default by financial institutions is limited to the amounts recorded on the condensed consolidated balance sheets. The Company performs periodic evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company has not experienced any losses on its deposits of cash and cash equivalents to date.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company generates revenue from fees charged for the trading of private placements on its marketplace platform, and fees for account and asset management provided to customers. The Company disaggregates revenue by service type, as management believes that this level of disaggregation best depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are impacted by economic factors. Revenue from Contracts with Customers The Company enters into contracts with customers that can include various services, which are capable of being distinct and accounted for as separate performance obligations. When applicable, an allocation of the transaction fees to the performance obligations or to the distinct goods or services that form part of a single performance obligation will depend on the individual facts and circumstances of the contract. All of the Company’s revenues are from contracts with customers. The Company is the principal in its contracts, with the exception of sub-account fees, in which the Company acts as an agent and records revenue from fees earned related to cash balances in customers’ custodial accounts. Each of our significant performance obligations and our application of ASC 606 to our revenue arrangements are discussed in further detail below: Placement Fees — The Company maintains a trading platform which generates revenues by collecting transaction fees from institutions, individual investors and private equity holders. Placement fees are charged by the Company for meeting the point-in-time performance obligation of executing a private placement on its platform. Placement fee rates are individually negotiated for each transaction and vary depending on the specific facts and circumstance of each agreement. These fees are event-driven and invoiced upon the closing of the transaction outlined in each agreement. These fees may be expressed as a dollar amount per share, a flat dollar amount, or a percentage of the gross transaction proceeds. The Company earns agency placement fees in non-underwritten transactions, such as private placements of equity securities. The Company enters into arrangements with individual accredited customers or pooled investment vehicles to execute private placements in the secondary market. The Company will receive placement fees on these transactions and believes that its trade execution performance obligation is completed upon the placement and consummation of a transaction and, as such, revenue is earned on the transaction date with no further obligation to the customer at that time. The Company acts as a principal and recognizes the placement fee revenue earned for the execution of a trade on a gross basis. Custodial Administration Fees — The Company generates revenues primarily by performing custodial account administration and maintenance services for its customers. Specifically, the Company charges administration fees for its services in maintaining custodial accounts, including asset-based fees, which are determined by the number and types of assets in these accounts. Additionally, the Company earns fees for opening and terminating accounts, and facilitating transactions, which are assessed at the point of transaction. Account and asset fees are assessed on the first day of the calendar quarter. Cash administration fees are based on cash balances within the custodial accounts and are assessed on the last day of the month. Revenues from custodial administration fees are recognized either over time as underlying performance obligations are met and day-to-day maintenance activities are performed for custodial accounts, or at a point in time upon completion of transactions requested by custodial account holders. Contract Balances Practical Expedients In certain arrangements, the Company receives payment from a customer either before or after the performance obligation has been satisfied; however, the contracts do not contain a significant financing component. The Company has applied the practical expedient in ASC 606 and excludes information about a) remaining performance obligations that have an original expected duration of one year or less and b) transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. The Company has also applied the practical expedient in accordance with ASC 340-40, Other Assets and Deferred Costs
Transaction-Based Expenses	Transaction-Based Expenses Transaction-based expenses represent the fees incurred to support placement and custodial activities. These include expenses for fund insurance, fund management and fund settlement expenses that relates to services
Warrant Liabilites	Warrant Liabilities The Public Warrants, Private Placement Warrants and the warrants issued in connection with the Merger (see Note 3 and 10) are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the carrying value of the instruments to fair value at each reporting period until they are exercised. The Company will continue to adjust the warrant liability for changes in the fair value until the earlier of a) the exercise or expiration of the warrants or b) the redemption of the warrants, at which time the warrants will be reclassified to additional paid-in-capital.
Recently Adopted and Issued Accounting Pronouncements	Recent Accounting Pronouncements As an “emerging growth company,” the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election and no new accounting pronouncements were adopted during the period. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, with subsequent amendments, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires immediate recognition of management’s estimates of current expected credit losses. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2022, and interim periods within that fiscal year, with early adoption permitted. The Company is currently evaluating the impact of adoption on the consolidated financial statements.
