Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. In the opinion of management, all necessary adjustments (which consists of only normal recurring items) have been made to fairly present the Condensed Consolidated Financial Statements for the interim periods presented. Results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission (“SEC”). The Company is an “emerging growth company” (“EGC”), as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), following the consummation of the merger of CFAC and the Company. The Company has elected to use this extended transition period for complying with new or revised accounting standards, pursuant to Section 102(b)(1) of the JOBS Act, that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition periods provided by the JOBS Act. As result of this election, its consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates. Continuing Impact of COVID-19 The COVID-19 pandemic and the subsequent spread of multiple variants has continued to impact the global economy and financial markets. Given the amount of uncertainty currently regarding the scope and duration of the COVID-19 pandemic, the Company is unable to predict the precise impact the COVID-19 pandemic will have on the Company’s consolidated financial statements. In line with public markets and credit indices, the Company’s investments may be adversely impacted. Inflation Reduction Act On August 16, 2022, the Inflation Reduction Act (the “IRA”) was signed into law. The IRA contains a number of tax related provisions including a 15% minimum corporate income tax on certain large corporations as well as a 1% excise tax on stock repurchases. The Company is in the process of evaluating the IRA but does not expect it to have a material impact on the Company’s consolidated financial statements. Fair Value Measurements The Company categorizes its fair value measurements according to a three-level hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are defined as follows: • Level 1 – Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date; • Level 2 – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active; and • Level 3 – Inputs that are unobservable. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The carrying amounts of cash and cash equivalents and fees receivable approximate fair value due to the immediate or short-term maturity of these financial instruments. Investments Investments primarily consist of investments in GCM Funds and other funds the Company does not control, but is deemed to exert significant influence, and are generally accounted for using the equity method of accounting. Under the equity method of accounting, the Company records its share of the underlying income or loss of such entities, which reflects the net asset value of such investments. Management believes the net asset value of the funds is representative of fair value. The resulting gains and losses are included as investment income (loss) in the Condensed Consolidated Statements of Income. The Company’s equity method investments in the GCM Funds investing in private equity, real estate and infrastructure (“GCM PEREI Funds”) are valued based on the most recent available information, which typically has a delay of up to three months due to the timing of financial information received from the investments held by the GCM PEREI Funds. The Company records its share of capital contributions to and distributions from the GCM PEREI Funds within investments in the Condensed Consolidated Statements of Financial Condition during the three-month lag period. To the extent that management is aware of material events that affect the GCM PEREI Funds during the intervening period, the impact of the events would be disclosed in the notes to the Condensed Consolidated Financial Statements. For certain other debt investments, the Company has elected the fair value option. Such election is irrevocable and is made at the investment level at initial recognition. The debt investments are not publicly traded and are a Level 3 fair value measurement. For investments carried at fair value, the Company records the increase or decrease in fair value as investment income in the Condensed Consolidated Statements of Income. See Note 6 for additional information regarding the Company’s other investments. Leases The Company’s leases primarily consist of operating lease agreements for office space in various countries around the world, including for its headquarters in Chicago, Illinois. On January 1, 2022, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) on a prospective basis. As a result, prior periods were not adjusted. The new standard requires lessees to use a right-of-use (“ROU”) model where lease ROU assets and lease liabilities are recorded on the Condensed Consolidated Statements of Financial Condition for all operating leases with initial terms exceeding one year. Lease ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s remaining minimum lease obligations. The Company made a permitted accounting policy election not to apply the ROU model to short-term leases, which are defined as leases with initial terms of one year or less. The Company determines whether a contract contains a lease at inception. Lease ROU assets and lease liabilities are initially recognized on the lease commencement date based on the present value of the minimum lease payments over the lease term. When determining the lease term, the Company generally does not include options to renew as it is not reasonably certain at contract inception that the Company will exercise the option(s). The implicit rate is not generally readily determinable, so the Company uses its incremental borrowing rate to determine the present value of future minimum lease payments. Lease ROU assets may include initial direct costs incurred by the Company and are reduced by lease incentives. Operating lease expense is recognized on a straight-line basis over the lease term within general, administrative and other in the Condensed Consolidated Statements of Income. Rece ntly Issued Accounting Standards Recently Issued Accounting Standards – Adopted in Current Fiscal Year In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases (Topic 842) , which requires that operating leases be recorded as assets and liabilities in the statement of financial position, among other changes. The amendments in this ASU are effective for public business entities for annual reporting periods beginning after December 15, 2018. On June 3, 2020, the FASB extended the adoption date for all other entities to annual periods beginning after December 15, 2021, and interim periods within annual periods beginning after December 15, 2022, with early adoption permitted. The Company adopted this standard on January 1, 2022 on a prospective basis. Adoption increased both the Company’s assets and liabilities for the recorded lease ROU and lease liability, with no material impact to the Company’s Condensed Consolidated Statements of Income as expense for operating leases continues to be recognized on a straight-line basis. The Company elected to apply practical expedients provided in the guidance to not reassess: (1) whether expired or existing contracts are or contain leases, (2) existing lease classification and (3) initial direct costs. On adoption, t he Company recognized approximately $16 million of lease ROU assets and approximately $21 million of lease liabilities related to its operating leases in its Condensed Consolidated Financial Statements , including approximately $5 million that was reclassified from accrued rent (included in accrued expenses and other liabilities in the Condensed Consolidated Statements of Financial Condition as of December 31, 2021) to lease liabilities. Recently Issued Accounting Standards – To be Adopted in Future Periods In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which modifies ASC 740 to simplify the accounting for income taxes. The guidance, among other changes, (i) provides a policy election to not allocate consolidated income taxes when a member of a consolidated tax return is not subject to income tax and (ii) provides guidance to evaluate whether a step-up in tax basis of goodwill relates to a business combination in which book goodwill was recognized or a separate transaction. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted. The Company will defer adoption until the guidance is effective for non-public entities, as the Company currently qualifies as an EGC and has elected to take advantage of the extended transition period afforded to EGCs as it applies to the adoption of new accounting standards. The method of adoption varies for the updates included in the ASU. The Company is evaluating this guidance but currently expects that adoption will not have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments . ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016-13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. This guidance is for public business entities that are an SEC filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, with fiscal years beginning after December 15, 2019. On March 9, 2020, the FASB extended the adoption date for all other entities to annual period s beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating this guidance but currently expects that adoption will not have a material impact on its consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Mosaic Transaction	Mosaic Transaction Prior to Amendment and Exercise of Mosaic Call Right Effective January 1, 2020, the Partnership and several subsidiaries, (collectively, the “Seller”) entered into a Purchase and Sale Agreement (“Agreement”) and issued certain limited partnership interests in several subsidiaries (“Carry Plan Entities”) to Mosaic Acquisitions 2020, L.P. (“Mosaic”). In addition, Mosaic also acquired the rights to receive a percentage of carried interest from certain GCM Funds and agreed to provide additional funding under certain circumstances up to a maximum amount as defined in the Agreement (collectively, the “Mosaic Transaction”). Mosaic issued Class A and Class B equity interests to GCMH, Holdings and Mosaic Feeder, L.P. (“Mosaic Feeder”). The Partnership served as the general partner of Mosaic, which was consolidated as the Partnership holds a controlling financial interest in Mosaic. Mosaic Feeder was beneficially owned by Lakeshore Investments GP, LLC (“Lakeshore”), a related party, and an unaffiliated third-party investor (“Mosaic Counterparty”) and was not consolidated. On December 31, 2020, the Company paid $2.6 million to Mosaic Feeder for the right, but not the obligation, to require Mosaic Feeder to sell to GCMH all of the Class A and Class B equity interests held by Mosaic Feeder in Mosaic (the “Mosaic Call Right”) for a purchase price equal to the greater of 1.3x its investment or a 12% internal rate of return on its investment. Further, Mosaic Counterparty had the right, but not the obligation, to require the Partnership to acquire all of the Class A and Class B Interests held by Mosaic Feeder in Mosaic (the “Put Option”) for a purchase price equal to Mosaic Counterparty receiving the greater of 1.3x of its investment or a 12% internal rate of return on its investment (the “Put Price”). The Put Option could only be exercised if a Triggering Event as defined in the Agreement occurred, which management had deemed to be remote. If the Partnership declined to pay the Put Price, Mosaic Counterparty may either step in and act as the general partner of Mosaic and control Mosaic until Mosaic Counterparty recoups the Put Price or effect a transfer of the underlying assets of Mosaic to Mosaic Counterparty. Management determined that the Mosaic Transaction should be evaluated under the guidance in ASC 810 and concluded that Mosaic was accounted for as a variable interest entity (“VIE”). The Partnership was deemed the primary beneficiary and therefore consolidated Mosaic. In addition, the Partnership concluded that the Put Option was embedded in an equity host contract but did not meet the net settlement criterion of an embedded derivative and therefore no separate accounting was required. However, as the Put Option was not solely within the control of the Partnership, the noncontrolling interest related to Mosaic had been classified as mezzanine equity.

Interest Rate Derivatives Management determines the fair value of its interest rate derivative agreements based on the present value of expected future cash flows based on observable future LIBOR rates applicable to each swap contract using linear interpolation, inclusive of the risk of non-performance, using a discount rate appropriate for the duration. Other Investments Investments in the subordinated notes of a structured alternatives investment solution are not publicly traded and are classified as Level 3. Management determines the fair value of these other investments using a discounted cash flow analysis (“Cash Flow Analysis”). These positions were classified as Level 3 as of September 30, 2022 and December 31, 2021 because of the use of significant unobservable inputs in the Cash Flow Analysis as follows: September 30, 2022 December 31, 2021 Impact to Valuation from an Increase in Input 2 Significant Unobservable Inputs 1 Range Weighted Average Range Weighted Average Discount rate 3 25.5% – 26.5% 26.0 % 25.0% N/A Decrease Expected term (years) 10 – 15 N/A 10 – 15 N/A Decrease Expected return – liquid assets 4 2.0% – 6.0% 5.0 % 3.0% - 7.0% 4.9 % Increase Expected total value to paid in capital – private assets 5 1.32x – 2.40x 1.87x 1.20x – 2.65x 1.90x Increase ____________ (1) In determining these inputs, management considers the following factors including, but not limited to: liquidity, estimated yield, capital deployment, diversified multi-strategy appreciation, expected net multiple of investment capital across Private Assets investments, annual operating expenses, as well as investment guidelines such as concentration limits, position size, and investment periods. (2) Unless otherwise noted, this column represents the directional change in fair value of the Level 3 investments that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the opposite effect. (3) The discount rate was based on the relevant benchmark rate, spread, and yield migrations on related securitized assets. (4) Inputs were weighted based on actual and estimated expected return included in the range. (5) Inputs were weighted based on the actual and estimated commitments to the respective private asset investments included in the range . The resulting fair value of $9.8 million and $11.0 million was recorded within investments in the Condensed Consolidated Statements of Financial Condition as of September 30, 2022 and December 31, 2021, respectively. The following table presents changes in Level 3 assets measured at fair value for the three and nine months ended September 30, 2022: Three Months Ended Nine Months Ended Balance at beginning of period $ 9,956 $ 11,010 Change in fair value (193) (1,247) Balance at end of period $ 9,763 $ 9,763 Public Warrants The public warrants are valued using quoted market prices on the Nasdaq Stock Market LLC under the ticker GCMGW. Private Warrants The private warrants were classified as Level 3 as of September 30, 2022 and December 31, 2021 because of the use of significant unobservable inputs in the valuation, however the overall private warrant valuation and change in fair value are not material to the Condensed Consolidated Financial Statements. The valuations for the private warrants were determined to be $0.71 and $1.76 per unit as of September 30, 2022 and December 31, 2021, respectively. The resulting fair values of $0.6 million and $1.6 million were recorded within warrant liabilities in the Condensed Consolidated Statements of Financial Condition as of September 30, 2022 and December 31, 2021, respectively. See Note 8 for additional information regarding the warrant activity for the three and nine months ended September 30, 2022 .

Distributions to partners represent distributions made to GCMH Equityholders. On August 6, 2021, GCMG’s Board of Directors authorized a stock repurchase plan of up to an aggregate of $25.0 million, excluding fees and expenses, which may be used to repurchase shares of the Company’s outstanding Class A common stock and warrants to purchase shares of Class A common stock. Class A common stock and warrants may be repurchased from time to time in open market transactions, in privately negotiated transactions, including with employees or otherwise, pursuant to the requirements of Rule 10b5-1 and Rule 10b-18 of the Exchange Act, as well as to retire (by cash settlement or the payment of tax withholding amounts upon net settlement) equity-based awards granted under our 2020 Incentive Award Plan (and any successor plan thereto), with the terms and conditions of these repurchases depending on legal requirements, price, market and economic conditions and other factors. The Company is not obligated under the terms of the plan to repurchase any of its Class A common stock or warrants, the program has no expiration date and the Company may suspend or terminate the program at any time without prior notice. Any shares of Class A common stock and any warrants repurchased as part of this program will be canceled. On February 10, 2022, GCMG’s Board of Directors increased its stock repurchase authorization for shares and warrants by $20.0 million, from $25.0 million to $45.0 million. On May 5, 2022, GCMG’s Board of Directors further increased its stock repurchase authorization for shares and warrants by $20.0 million , from $45.0 million to $65.0 million . In the three and nine months ended September 30, 2022, the Company is deemed to have repurchased 679,687 and 740,699 shares withheld in connection with the payment of tax liabilities on behalf of employees upon the settlement of vested RSUs for $5.9 million and $6.4 million, or an average of $8.61 and $8.70 per share. In the nine months ended September 30, 2022, the Company repurchased 2,812,764 public warrants to purchase shares of Class A common stock for $2.6 million, or an average of $0.91 per warrant.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities The Company consolidates certain VIEs in which it is determined that the Company is the primary beneficiary. The Company holds variable interests in certain entities that are VIEs which are not consolidated, as it is determined that the Company is not the primary beneficiary. The Company’s involvement with such entities is generally in the form of direct equity interests in, and fee arrangements with, the entities in which it also serves as the general partner or managing member. The Company evaluated its variable interests in the VIEs and determined it is not considered the primary beneficiary of the entities primarily because it does not have interests in the entities that could potentially be significant. No reconsideration events that caused a change in the Company’s consolidation conclusions occurred during either the nine months ended September 30, 2022 or the year ended December 31, 2021. As of September 30, 2022 and December 31, 2021, the total unfunded commitments from the special limited partner and general partners to the unconsolidated VIEs were $35.3 million and $34.7 million, respectively. These commitments are the primary source of financing for the unconsolidated VIEs. The following table sets forth certain information regarding the VIEs in which the Company holds a variable interest but does not consolidate. The assets recognized on the Company’s Condensed Consolidated Statements of Financial Condition relate to the Company’s interests in and management fees, incentive fees and third party costs receivables from these non-consolidated VIEs. The Company’s maximum exposure to loss relating to non-consolidated VIEs as of September 30, 2022 and December 31, 2021 were as follows: As of September 30, 2022 December 31, 2021 Investments $ 101,653 $ 104,609 Receivables 15,590 13,554 Maximum exposure to loss $ 117,243 $ 118,163 The above table includes investments in VIEs which are owned by noncontrolling interest holders of approximately $40.7 million and $50.4 million as of September 30, 2022 and December 31, 2021, respectively.

Employee Compensation and Benefits	Employee Compensation and Benefits For the three and nine months ended September 30, 2022 and 2021, employee compensation and benefits consisted of the following: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Cash-based employee compensation and benefits $ 39,833 $ 39,792 $ 121,997 $ 122,629 Equity-based compensation 5,706 5,878 21,191 38,518 Partnership interest-based compensation 7,329 6,029 21,471 20,958 Carried interest compensation 25,946 16,708 37,840 41,164 Cash-based incentive fee related compensation 7,367 3,380 10,180 6,081 Other non-cash compensation 321 1,080 1,157 2,704 Total employee compensation and benefits $ 86,502 $ 72,867 $ 213,836 $ 232,054 Partnership Interest in Holdings, Holdings II and Management LLC Payments to the employees for partnership interest awards are made by Holdings, Holdings II and Management LLC. As a result, the Company records a non-cash profits interest compensation charge and an offsetting deemed contribution to equity (deficit) to reflect the payments made by the GCMH Equityholders. As the payments are made by Holdings, Holdings II and Management LLC, the expense that is pushed down to GCMH and the offsetting deemed contribution are each attributed solely to noncontrolling interests in GCMH. Any liability related to the awards is recognized at Holdings, Holdings II or Management LLC as Holdings, Holdings II or Management LLC is the party responsible for satisfying the obligation, and is not shown in the Company’s Condensed Consolidated Financial Statements. The Company has recorded deemed contributions to equity (deficit) from Holdings, Holdings II and Management LLC of approximately $7.3 million and $6.0 million for the three months ended September 30, 2022 and 2021, respectively, and $21.5 million and $21.0 million for the nine months ended September 30, 2022 and 2021, respectively, for partnership interest-based compensation expense which will ultimately be paid by Holdings, Holdings II or Management LLC. The Company has modified awards to certain individuals upon their voluntary retirement or intention to retire as employees. These awards generally include a stated target amount that, upon payment, terminates the recipient’s rights to future distributions and allows for a lump sum buy-out of the awards, at the discretion of the managing member of Holdings, Holdings II, and Management LLC. The awards are accounted for as partnership interest-based compensation at the fair value of these expected future payments, in the period the employees accepted the offer. Partnership interest-based compensation expense related to award modifications of $1.6 million was recognized for each of the three months ended September 30, 2022 and 2021, and $4.7 million was recognized for each of the nine months ended September 30, 2022 and 2021. The liability associated with awards that contain a stated target has been retained by Holdings as of September 30, 2022 and December 31, 2021 and is re-measured at each reporting date, with any corresponding changes in liability being reflected as employee compensation and benefits expense of the Company. Certain recipients had unvested stated target payments of $1.6 million and $7.8 million as of September 30, 2022 and 2021 , respectively, which has not been reflected as employee compensation and benefits expense by the Company. The Company recognized partnership interest-based compensation expense of $5.6 million and $4.5 million for the three months ended September 30, 2022 and 2021, respectively, and $16.6 million and $16.3 million for the nine months ended September 30, 2022 and 2021, respectively, related to profits interest awards that are in substance profit-sharing arrangements. In the third quarter of 2022, GCMH Equityholders entered into an agreement that will transfer equity ownership between certain existing employee members of the GCMH Equityholders (“GCMH Equityholders Awards”). The GCMH Equityholders Awards will entitle recipients to receive Class A common stock upon vesting. The non-cash awards serve to transfer equity ownership from existing GCMH Equityholders to other existing member employees upon vesting. The GCMH Equityholders Awards do not dilute Class A common stockholders and do not impact cash flows of the Company. The GCMH Equityholders Awards are accounted for under ASC 718, Compensation—Stock Compensation . The awards generally will vest in May 2025 and do not entitle the recipients to dividends or distributions made on Class A common stock during the vesting period. As such, the fair value of the GCMH Equityholders Awards is based on the closing price of Class A common stock on the accounting grant date less the present value of dividends expected to be paid during the vesting period. GCMH Equityholders can settle the awards upon vesting by exchanging outstanding GCMH common units or by otherwise acquiring and delivering Class A common stock, and therefore the vesting of such awards will not dilute Class A common stockholders. The GCMH Equityholders Awards therefore have no economic impact on Class A common stockholders. As such, the expense that is pushed down to GCMH and the offsetting deemed contribution are each attributed solely to noncontrolling interests in GCMH, consistent with the accounting for payments to employees described above. The GCMH Equityholders Awards had an aggregate grant date fair value of $15.5 million. The Company recognized partnership interest-based compensation expense related to the GCMH Equityholders Awards of $0.2 million for each of the three and nine months ended September 30, 2022. As of September 30, 2022, total unrecognized compensation expense related to unvested GCMH Equityholders Awards was $15.3 million and is expected to be recognized over the remaining weighted average period of 2.6 years. Other Other consists of employee compensation and benefits expense related to deferred compensation programs and other awards that represent investments made in GCM Funds on behalf of the employees.

On February 24, 2021, the Company completed an amendment and extension of its Senior Loan to further extend the maturity (“Amended Credit Agreement”). Approximately $290.0 million of the aggregate principal amount of the Senior Loan was extended from a maturity date of March 29, 2025 (the “2025 Term Loans”) to a maturity date of February 24, 2028 , (as extended, the “2028 Term Loans”). The 2028 Term Loans have an interest rate of 2.50% over the LIBOR, subject to a 0.50% LIBOR floor. In the event of a Benchmark Transition Event, the interest rate will default to the Term Secured Overnight Financing Rate (“Term SOFR”) plus a Benchmark Replacement Adjustment as recommended by the Relevant Governmental Body (all terms as defined in the Amended Credit Agreement). Concurrently with the effectiveness of the Amended Credit Agreement, the Company made a voluntary prepayment on the Senior Loan in an aggregate principal amount of $50.3 million. As a result of the prepayment in February 2021, the Company recorded an expense of $0.7 million related to the acceleration of deferred debt issuance costs, which was recorded within other income in the Condensed Consolidated Statements of Income for the nine months ended September 30, 2021. The Company capitalized $0.9 million of debt issuances costs related to payments to lenders in connection with the amendment and extension of its Senior Loan, which was recorded within debt in the Condensed Consolidated Statements of Financial Condition, and expensed $2.6 million of third-party costs related to the amendment which was recorded within general, administrative and other in the Condensed Consolidated Statements of Income for the nine months ended September 30, 2021. On June 23, 2021, the Company further amended its Senior Loan to increase the aggregate principal amount from $290.0 million to $400.0 million (as increased, the “Incremental 2028 Term Loans”). The Company capitalized $2.2 million of debt issuance costs related to payments to lenders in connection with the Incremental 2028 Term Loans, which was recorded within debt in the Condensed Consolidated Statements of Financial Condition. Quarterly principal payments of $1.0 million are required to be made toward the Incremental 2028 Term Loans beginning June 30, 2021 (less any reduction for prior or future voluntary or mandatory prepayments of principal). In addition to the scheduled principal repayments, the Company is required to offer to make prepayments of Consolidated Excess Cash Flow (“Cash Flow Payments”) no later than five days following the date the quarterly financial statements are due if the leverage ratio exceeds 2.50x. The Cash Flow Payments were calculated as defined in the Senior Loan agreement based on a percentage of calculated excess cash. During the three and nine months ended September 30, 2022, the Company did not make any Cash Flow Payments. As of September 30, 2022 and December 31, 2021, $394.0 million and $397.0 million of Incremental 2028 Term Loans were outstanding, respectively, with weighted average interest rates of 3.65% and 3.25% for the nine months ended September 30, 2022 and 2021, respectively. Under the credit and guaranty agreement governing the terms of the Senior Loan, the Company must maintain certain leverage and interest coverage ratios. The credit and guaranty agreement also contains other covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur debt and restrict the Company and its subsidiaries ability to merge or consolidate, or sell or convey all or substantially all of the Company’s assets. As of September 30, 2022, the Company was in compliance with all covenants. GCMH Equityholders and IntermediateCo have executed a pledge agreement (“Pledge Agreement”) and security agreement (“Security Agreement”) with the lenders of the Senior Loan. Under the Pledge Agreement, GCMH Equityholders and IntermediateCo have agreed to secure the obligations under the Senior Loan by pledging its interests in GCMH as collateral against the repayment of the senior secured notes, and GCMH has agreed to secure the obligations under the Senior Loan by granting a security interest in and continuing lien on the collateral described in the Security Agreement. The Pledge Agreement and Security Agreement will remain in effect until such time as all obligations relating to the Senior Loan have been fulfilled. Credit Facility Concurrent with the issuance of the Senior Loan, the Company entered into a $50.0 million revolving credit facility (“Credit Facility”). The Credit Facility matures on February 24, 2026 and carries an unused commitment fee that is paid quarterly. There were no outstanding borrowings related to the Credit Facility as of each of September 30, 2022 and December 31, 2021. Other Certain subsidiaries of the Company agree to jointly and severally guarantee, as primary obligor and not merely as surety guarantee the obligations of their parent entity, GCMH. Amortization of deferred debt issuance costs was $0.2 million for each of the three months ended September 30, 2022 and 2021, and $0.8 million and $0.7 million for the nine months ended September 30, 2022 and 2021, respectively. These amounts were recorded within interest expense in the Condensed Consolidated Statements of Income. The carrying value of the Senior Loan, excluding the unamortized debt issuance costs presented as a reduction to the principal balance, approximated the fair value as of September 30, 2022 and December 31, 2021 . As the Senior Loan was not accounted for at fair value, it was not included in the Company’s fair value hierarchy in Note 6, however had it been included, it would have been classified in Level 2.

The Company had the following interest rate derivatives recorded as an asset within other assets in the Condensed Consolidated Statements of Financial Condition as of September 30, 2022 and December 31, 2021: Derivative Notional Amount Fair Value as of September 30, 2022 Fair Value as of December 31, 2021 Fixed Rate Paid Floating Rate Received Effective Date (2) Maturity Date Interest rate swap $ 232,000 $ 30,309 $ 2,264 1.33 % 1 month LIBOR (1) March 2021 February 2028 Interest rate swap 68,000 8,694 431 1.39 % 1 month LIBOR (1) July 2021 February 2028 $ 39,003 $ 2,695 ____________ (1) Floating rate received subject to a 0.50% Floor. Refer to Note 12 regarding the interest rate on the outstanding debt in the event of a Benchmark Transition Event. If the outstanding debt defaults to Term SOFR plus a Benchmark Replacement Adjustment, the floating rate received under the interest rate swaps will also default to such rate. (2) Represents the date at which the derivative is in effect and the Company is contractually required to begin payment of interest under the terms of the agreement. A rollforward of the amounts in accumulated other comprehensive income (loss) (“AOCI”) related to interest rate derivatives designated as cash flow hedges is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Derivative gain (loss) at beginning of period $ 22,892 $ (9,819) $ (3,622) $ (11,163) Amount recognized in other comprehensive income 12,489 (13) 35,241 (1,633) Amount reclassified from accumulated other comprehensive loss to interest expense 1,372 2,018 5,134 4,982 Derivative gain (loss) at end of period 36,753 (7,814) 36,753 (7,814) Less: gain (loss) attributable to noncontrolling interests in GCMH 28,090 (6,171) 28,090 (6,171) Derivative gain (loss) at end of period, net $ 8,663 $ (1,643) $ 8,663 $ (1,643) On February 24, 2021, the Company terminated derivative instruments which were entered into in 2017 and 2018. Prior to termination, certain derivative instruments did not qualify for hedge accounting due to floor rate mismatches and as a result, all changes in fair value for those derivative instruments were reflected within other income (expense) in the Condensed Consolidated Statements of Income. The amount previously recorded as a hedge in AOCI remains in AOCI and was recorded in interest expense within the Condensed Consolidated Statements of Income over the original life of the swap. The Company reclassified $1.4 million for each of the three months ended September 30, 2022 and 2021, and $4.1 million and $3.3 million for the nine months ended September 30, 2022 and 2021, respectively, from AOCI to interest expense relating to the terminated derivative instrument that initially qualified for hedge accounting. Prior to terminating the instruments in February 2021, the Company recognized a gain of $1.9 million related to interest rate contracts not designated as hedging instruments, which was recorded within other income (expense) in the Condensed Consolidated Statements of Income during the nine months ended September 30, 2021. Effective on March 1, 2021 , the Company entered into a swap agreement (“2028 Swap Agreement”) to hedge interest rate risk related to payments made during the extended maturity of the 2028 Term Loans that has a notional amount of $232.0 million. The 2028 Swap Agreement and 2028 Term Loans have a 0.50% LIBOR floor. The swap was determined to be an effective cash flow hedge at inception based on a comparison of critical terms. Effective on July 1, 2021 , the Company entered into a swap agreement (“2028 Incremental Swap Agreement”) to hedge interest rate risk related to payments made for the increase in aggregate principal amount of the Incremental 2028 Term Loans that has a notional amount of $68.0 million. The 2028 Incremental Swap Agreement and Incremental 2028 Term Loans have a 0.50% LIBOR floor. The swap was determined to be an effective cash flow hedge at inception based on a comparison of critical terms. The fair values of the interest rate swaps are based on observable market inputs and represent the net amount required to terminate the positions, taking into consideration market rates and non-performance risk. Refer to Note 6 for further details. As of September 30, 2022, all of the Company’s derivative exposure is with one financial institution. By using derivatives, the Company is exposed to counterparty credit risk if the counterparty to the derivative contracts does not perform as expected. If a counterparty fails to perform, the Company's counterparty credit risk is equal to the amount reported as a derivative asset in the Condensed Consolidated Statements of Financial Condition. The Company minimizes counterparty credit risk through credit approvals and monitoring procedures, where appropriate. See Note 18 for more information regarding the Company’s termination of the 2028 Swap Agreement and 2028 Incremental Swap Agreement effective November 1, 2022. During the next twelve months, the Company expects to reclassify approximately $5.1 million

The Company provides certain employees partnership interest awards which are paid by Holdings, Holdings II and Management LLC. Refer to Note 10 for further details. The Company has a sublease agreement with Holdings. Because the terms of the sublease are identical to the terms of the original lease, there is no impact to net income in the Condensed Consolidated Statements of Income or Condensed Consolidated Statements of Cash Flows. The Company incurs certain costs, primarily related to accounting, client reporting, investment-decision making and treasury-related expenditures, for which it receives reimbursement from the GCM Funds in connection with its performance obligations to provide investment management services. Due from related parties in the Condensed Consolidated Statements of Financial Condition includes net receivables of $11.9 million and $11.7 million as of September 30, 2022 and December 31, 2021, respectively, paid on behalf of affiliated entities that are reimbursable to the Company. Our executive officers, senior professionals, and certain current and former employees and their families invest on a discretionary basis in GCM Funds, and such investments are generally not subject to management fees and performance fees. As of September 30, 2022 and December 31, 2021, such investments and future commitments were $378.8 million and $441.8 million in aggregate, respectively. Certain employees of the Company have an economic interest in an entity that is the owner and landlord of the building in which the principal headquarters of the Company are located.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate used for interim periods is based on the tax effect of items recorded discretely in the interim period in which those items occur. The effective tax rate is dependent on many factors, including the estimated amount of income subject to income tax and allocation of tax benefit to noncontrolling interest; therefore, the effective tax rate can vary from period to period. The Company evaluates the realizability of its deferred tax asset on a quarterly basis and adjusts the valuation allowance when it is expected a portion of the deferred tax asset may not be realized. The Company’s effective tax rate was 16% and 10% for the three months ended September 30, 2022 and 2021, respectively, and 9% and 6% for the nine months ended September 30, 2022 and 2021, respectively. These rates were different than the statutory rate primarily due to the portion of income allocated to the noncontrolling interest holders, a valuation allowance recorded against deferred tax assets and discrete tax adjustments recorded in the periods. As of September 30, 2022, the Company had no unrecognized tax positions and believes there will be no changes to uncertain tax positions within the next 12 months.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. In the opinion of management, all necessary adjustments (which consists of only normal recurring items) have been made to fairly present the Condensed Consolidated Financial Statements for the interim periods presented. Results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission (“SEC”). The Company is an “emerging growth company” (“EGC”), as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), following the consummation of the merger of CFAC and the Company. The Company has elected to use this extended transition period for complying with new or revised accounting standards, pursuant to Section 102(b)(1) of the JOBS Act, that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition periods provided by the JOBS Act. As result of this election, its consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.
Fair Value Measurements	Fair Value Measurements The Company categorizes its fair value measurements according to a three-level hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are defined as follows: • Level 1 – Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date; • Level 2 – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active; and • Level 3 – Inputs that are unobservable. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The carrying amounts of cash and cash equivalents and fees receivable approximate fair value due to the immediate or short-term maturity of these financial instruments.
Investments	Investments Investments primarily consist of investments in GCM Funds and other funds the Company does not control, but is deemed to exert significant influence, and are generally accounted for using the equity method of accounting. Under the equity method of accounting, the Company records its share of the underlying income or loss of such entities, which reflects the net asset value of such investments. Management believes the net asset value of the funds is representative of fair value. The resulting gains and losses are included as investment income (loss) in the Condensed Consolidated Statements of Income. The Company’s equity method investments in the GCM Funds investing in private equity, real estate and infrastructure (“GCM PEREI Funds”) are valued based on the most recent available information, which typically has a delay of up to three months due to the timing of financial information received from the investments held by the GCM PEREI Funds. The Company records its share of capital contributions to and distributions from the GCM PEREI Funds within investments in the Condensed Consolidated Statements of Financial Condition during the three-month lag period. To the extent that management is aware of material events that affect the GCM PEREI Funds during the intervening period, the impact of the events would be disclosed in the notes to the Condensed Consolidated Financial Statements.
Leases	Leases The Company’s leases primarily consist of operating lease agreements for office space in various countries around the world, including for its headquarters in Chicago, Illinois. On January 1, 2022, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) on a prospective basis. As a result, prior periods were not adjusted. The new standard requires lessees to use a right-of-use (“ROU”) model where lease ROU assets and lease liabilities are recorded on the Condensed Consolidated Statements of Financial Condition for all operating leases with initial terms exceeding one year. Lease ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s remaining minimum lease obligations. The Company made a permitted accounting policy election not to apply the ROU model to short-term leases, which are defined as leases with initial terms of one year or less.
Recently Issued Accounting Standards	Rece ntly Issued Accounting Standards Recently Issued Accounting Standards – Adopted in Current Fiscal Year In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases (Topic 842) , which requires that operating leases be recorded as assets and liabilities in the statement of financial position, among other changes. The amendments in this ASU are effective for public business entities for annual reporting periods beginning after December 15, 2018. On June 3, 2020, the FASB extended the adoption date for all other entities to annual periods beginning after December 15, 2021, and interim periods within annual periods beginning after December 15, 2022, with early adoption permitted. The Company adopted this standard on January 1, 2022 on a prospective basis. Adoption increased both the Company’s assets and liabilities for the recorded lease ROU and lease liability, with no material impact to the Company’s Condensed Consolidated Statements of Income as expense for operating leases continues to be recognized on a straight-line basis. The Company elected to apply practical expedients provided in the guidance to not reassess: (1) whether expired or existing contracts are or contain leases, (2) existing lease classification and (3) initial direct costs. On adoption, t he Company recognized approximately $16 million of lease ROU assets and approximately $21 million of lease liabilities related to its operating leases in its Condensed Consolidated Financial Statements , including approximately $5 million that was reclassified from accrued rent (included in accrued expenses and other liabilities in the Condensed Consolidated Statements of Financial Condition as of December 31, 2021) to lease liabilities. Recently Issued Accounting Standards – To be Adopted in Future Periods In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which modifies ASC 740 to simplify the accounting for income taxes. The guidance, among other changes, (i) provides a policy election to not allocate consolidated income taxes when a member of a consolidated tax return is not subject to income tax and (ii) provides guidance to evaluate whether a step-up in tax basis of goodwill relates to a business combination in which book goodwill was recognized or a separate transaction. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted. The Company will defer adoption until the guidance is effective for non-public entities, as the Company currently qualifies as an EGC and has elected to take advantage of the extended transition period afforded to EGCs as it applies to the adoption of new accounting standards. The method of adoption varies for the updates included in the ASU. The Company is evaluating this guidance but currently expects that adoption will not have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments . ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016-13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. This guidance is for public business entities that are an SEC filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, with fiscal years beginning after December 15, 2019. On March 9, 2020, the FASB extended the adoption date for all other entities to annual period s beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating this guidance but currently expects that adoption will not have a material impact on its consolidated financial statements.
