Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation and Summary of Significant Accounting Policies	ORGANIZATION, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Orga nization UWM Holdings Corporation, through its consolidated subsidiaries (collectively, the “Company”), engages in the origination, sale and servicing of residential mortgage loans. The Company is organized in Delaware but based in Michigan, and originates and services loans throughout the U.S. The Company is approved as a Title II, non-supervised direct endorsement mortgagee with the U.S. Department of Housing and Urban Development (or “HUD”). In addition, the Company is an approved issuer with the Government National Mortgage Association (or “Ginnie Mae”), as well as an approved seller and servicer with the Federal National Mortgage Association (or “Fannie Mae”) and the Federal Home Loan Mortgage Corporation (or “Freddie Mac”). The Company (f/k/a Gores Holdings IV, Inc.) was incorporated in Delaware on June 12, 2019. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. On September 22, 2020, the Company entered into a Business Combination Agreement (the “Business Combination Agreement”) by and among the Company, SFS Holding Corp., a Michigan corporation (“SFS Corp.”), United Wholesale Mortgage, LLC, a Michigan limited liability company (“UWM”), and UWM Holdings, LLC, a newly formed Delaware limited liability company (“Holdings LLC” and, together with UWM, the “UWM Entities”). The business combination with the UWM Entities closed on January 21, 2021. Prior to the closing of the business combination with the UWM Entities, SFS Corp. was the sole member of UWM, which had one unit authorized, issued and outstanding. On January 21, 2021, SFS Corp. contributed its equity interest in UWM to Holdings LLC and adopted the Amended and Restated Operating Agreement to admit Holdings LLC as UWM's sole member and its manager. Upon completion of the business combination transaction, (i) Holdings LLC issued approximately 6% of its units (Class A Common Units) to the Company, (ii) SFS Corp. retained approximately 94% of the units (Class B Common Units) in Holdings LLC and accordingly retained approximately 94% of the economic ownership interest of the combined company and (iii) Holdings LLC became a consolidated subsidiary of the Company, as the Company is the sole managing member of Holdings LLC. The economic interest in Holdings LLC owned by SFS Corp. is presented as a non-controlling interest in these condensed consolidated financial statements. See Note 11 - Non-Controlling Interests for further information. Following the consummation of the transactions contemplated by the Business Combination Agreement, the Company is organized in an “Up-C” structure in which UWM (the operating subsidiary) is held directly by Holdings LLC, and the Company’s only material direct asset consists of Class A Common Units in Holdings LLC. The Company’s current capital structure authorizes Class A common stock, Class B common stock, Class C common stock and Class D common stock. The Class A common stock and Class C common stock each provide holders with one vote on all matters submitted to a vote of stockholders, and the Class B common stock and Class D common stock each provide holders with 10 votes on all matters submitted to a vote of stockholders. The holders of Class C common stock and Class D common stock do not have any of the economic rights (including rights to dividends and distributions upon liquidation) provided to holders of Class A common stock and Class B common stock. Each Holdings LLC Class B Common Unit held by SFS Corp. may be exchanged at the option of the Company, along with its stapled share of Class D common stock, for either, (a) cash or (b) one share of the Company’s Class B common stock. Each share of Class B common stock is convertible into one share of Class A common stock upon the transfer or assignment of such share from SFS Corp. to a non-affiliated third-party. See Note 11 - Non-Controlling Interests for further information. Pursuant to the Business Combination Agreement, SFS Corp. is entitled to receive an aggregate of up to 90,761,687 earn-out shares in the form of Class B Common Units in Holdings LLC and Class D common shares upon attainment of certain stock price targets prior to January 2026. There are four different triggering events that affect the number of earn-out shares that will be issued based upon the per share price of Class A common stock ranging from $13.00 to $19.00 per share. The Company accounts for the potential earn-out shares as a component of stockholders’ equity in accordance with the applicable guidance in U.S. GAAP. See Note 17 - Earnings Per Share for further information. Upon completion of the business combination transaction, the directors and officers of Gores Holdings IV, Inc. (the “Gores Directors and Officers”) resigned, the Company appointed new directors to its Board, and certain officers of UWM became officers of the Company. Pursuant to the Business Combination Agreement, the Company has potential indemnification obligations to the Gores Directors and Officers for costs or losses incurred prior to or after the closing of the business combination transaction that arose by reason of the fact that he or she is or was a director or officer of Gores Holdings IV, Inc . The Gores Directors and Officers have been named as defendants in class action suits in Delaware Chancery Court in which it is alleged that they breached their fiduciary duties to shareholders of Gores Holdings, IV. Pursuant to its obligations under the Business Combination Agreement, to the extent that it is determined that the Gores Directors and Officers are entitled to indemnification, the Company is obligated to indemnify them in connection with these lawsuits. The Company has insurance which it believes will cover any material liability that could arise pursuant to its indemnification obligations to the Gores Directors and Officers. This insurance includes two separate towers of coverage with limits in excess of the Company's current estimate of any reasonably possible liability, and a deductible of $20.5 million. Basis of Presentation and Consolidation The condensed consolidated financial statements are unaudited and presented in U.S. dollars. They have been prepared in accordance with U.S. GAAP pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In our opinion, these condensed consolidated financial statements include all normal and recurring adjustments considered necessary for a fair statement of our results of operations, financial position and cash flows for the periods presented. However, our results of operations for any interim period are not necessarily indicative of the results that may be expected for a full fiscal year or for any other future period. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. 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 condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Loans Eligible for Repurchase from Ginnie Mae For certain loans sold to Ginnie Mae, the Company as the servicer has the unilateral right to repurchase any individual loan in a Ginnie Mae pool if that loan meets defined criteria (generally loans that are more than 90 days past due). When the Company has the unilateral right to repurchase the delinquent loans, the previously sold assets are required to be re-recognized on the condensed consolidated balance sheets as assets and corresponding liabilities at the loan's unpaid principal balance, regardless of the Company’s intent to exercise its option to repurchase. The recognition of previously sold loans does not impact the accounting for the previously recognized mortgage servicing rights (or "MSRs"). Income Taxes The Company accounts for income taxes during interim periods by applying an estimated annual effective tax rate to year-to-date earnings (loss) before income taxes to compute the year-to-date tax expense (or benefit). At the end of each interim period, the Company estimates the effective tax rate expected to be applicable for the full fiscal year, adjusted for discrete items, if any, that arise during the period. See Note 15 – Income Taxes for further information. Tax Receivable Agreement The Company has entered into a Tax Receivable Agreement ("TRA") with SFS Corp. that will obligate the Company to make payments to SFS Corp. of 85% of the amount of cash savings, if any, in federal, state and local income tax that the Company actually realizes as a result of (i) certain increases in tax basis resulting from exchanges of Holdings LLC common units; (ii) imputed interest deemed to be paid by the Company as a result of payments it makes under the tax receivable agreement; (iii) certain increases in tax basis resulting from payments the Company makes under the tax receivable agreement; and (iv) disproportionate allocations (if any) of tax benefits to the Company which arise from, among other things, the sale of certain assets as a result of taxable income allocation rules in the United States. The Company will retain the benefit of the remaining 15% of these tax savings. The Company accounts for liabilities arising from the TRA as a loss contingency recorded within "Accounts payable, accrued expenses and other." Changes in the liability are measured and recorded when estimated amounts due under the TRA are probable and can be reasonably estimated, and reported as part of "Other expense/(income)" in the condensed consolidated statements of operations. See Note 9 - Accounts Payable, Accrued Expenses and Other for further information. Related Party Transactions The Company enters into various transactions with related parties. See Note 14 – Related Party Transactions for further information. Public and Private Warrants As part of Gores Holdings IV, Inc.'s initial public offering ("IPO") in January 2020, Gores Holdings IV, Inc. issued to third party investors 42.5 million units, consisting of one share of Class A common stock of Gores Holdings IV, Inc. and one-fourth of one warrant, at a price of $10.00 per unit. Each whole warrant entitles the holder to purchase one share of Class A common stock at an exercise price of $11.50 per share (the “Public Warrants”). Simultaneously with the closing of the IPO, Gores Holdings IV, Inc. completed the private sale of 5.25 million warrants to Gores Holdings IV, Inc.'s sponsor at a purchase price of $2.00 per warrant (the “Private Warrants”). Each Private Warrant allows the sponsor to purchase one share of Class A common stock at $11.50 per share. Upon the closing of the business combination transaction, the Company had 10,624,987 Public Warrants and 5,250,000 Private Warrants outstanding. The Private Warrants and the shares of common stock issuable upon the exercise of the Private Warrants were not transferable, assignable or salable until after the completion of the business combination, subject to certain limited exceptions. Additionally, the Private Warrants are exercisable for cash or on a cashless basis, at the holder’s option, and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company evaluated the Public and Private Warrants under applicable U.S. GAAP and concluded that they do not meet the criteria to be classified in stockholders’ equity due to certain terms of the warrants. Since the Public and Private Warrants meet the definition of derivatives, the Company recorded these warrants as liabilities on the balance sheet at fair value upon the closing of the business combination transaction and subsequently (recorded within "Accounts payable, accrued expenses and other"), with the change in their respective fair values recognized in the condensed consolidated statement of operations (recorded within "Other expense/(income)"). Stock-Based Compensation Effective upon the closing of the business combination transaction, the Company adopted the UWM Holdings Corporation 2020 Omnibus Incentive Plan (the “2020 Plan”) which was approved by stockholders on January 20, 2021. The 2020 Plan allows for the grant of stock options, restricted stock, restricted stock units (“RSUs”), and stock appreciation rights. Pursuant to the 2020 Plan, the Company reserved a total of 80,000,000 shares of common stock for issuance of stock-based compensation awards, a nd 68,744,413 sh ares remained available for issuance under the 2020 Plan as of March 31, 2024 . Stock-based compensation expense is recognized on a straight-line basis over the requisite service period based on the fair value of the award on the date of grant and is included in "Salaries, commissions and benefits" on the condensed consolidated statements of operations. The Company made a policy election to recognize the effects of forfeitures as they occur. See Note 16 – Stock-based Compensation for further information. Recently Adopted Accounting Standards In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2023-1, Leases (Topic 842): Common Control Arrangements , which amends certain provisions of ASU 2016-2, Leases (Topic 842) . This guidance requires all lessees in a lease with a lessor under common control to amortize leasehold improvements over the useful life of the common control group and provides new guidance for recognizing a transfer of assets between entities under common control as an adjustment to equity when the lessee no longer controls the use of the underlying asset. There was no impact on the Company's condensed consolidated financial statements from adopting this standard effective the fiscal year beginning January 1, 2024. Accounting Standards Issued but Not Yet Effective In November 2023, the FASB issued ASU 2023-7, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires enhanced disclosure of significant segment expenses on an annual and interim basis. The ASU is effective on a retrospective basis for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted. The Company will include the required disclosures in its consolidated financial statements once adopted. In December 2023, the FASB issued ASU 2023-9 , Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024, and early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The Company will include the required disclosures in its condensed consolidated financial statements once adopted.

Mortgage Loans at Fair Value	MORTGAGE LOANS AT FAIR VALUE The table below includes the estimated fair value and unpaid principal balance (“UPB”) of mortgage loans that have contractual principal amounts and for which the Company has elected the fair value option. The fair value option has been elected for mortgage loans, as this accounting treatment best reflects the economic consequences of the Company’s mortgage origination and related hedging and risk management activities. The difference between the UPB and estimated fair value is made up of the premiums paid on mortgage loans, as well as the fair value adjustment as of the balance sheet date. The change in fair value adjustment is recorded in the “Loan production income” line item of the condensed consolidated statements of operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	DERIVATIVES The Company enters into interest rate lock commitments (“IRLCs”) to originate residential mortgage loans at specified interest rates and terms within a specified period of time with customers who have applied for a loan and may meet certain credit and underwriting criteria. To determine the fair value of the IRLCs, each contract is evaluated based upon its stage in the application, approval and origination process for its likelihood of consummating the transaction (or “pullthrough”). Pullthrough is estimated based on changes in market conditions, loan stage, and actual borrower behavior using a historical analysis of IRLC closing rates. Generally, the further into the process the more likely that the IRLC will convert to a loan. The blended average pullthrough rate was 79% and 76% as of March 31, 2024 and December 31, 2023, respectively. The Company primarily uses forward loan sale commitments (“FLSCs”) to economically hedge its pipeline of IRLCs and mortgage loans at fair value.

Mortgage Servicing Rights

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	MORTGAGE SERVICING RIGHTS Mortgage servicing rights are recognize d on the condensed consolidated balance sheets when loans are sold and the associated servicing rights are retained. The Company's MSRs are measured at fair value, which is determined u sing a valuation model that calculates the present value of estimated future net servicing cash flows. The model includes estimates of prepayment speeds, discount rate, cost to service, float earnings, contractual servicing fee income, and ancillary income and late fees, among others. These estimates are supported by market and economic data collected from various external sources. The unpaid principal balance of mortgage loans serviced for others approximated $229.7 billion and $299.5 billion at March 31, 2024 and December 31, 2023, respectively. Conforming conventional loans serviced by the Company have previously been sold to Fannie Mae and Freddie Mac on a non-recourse basis, whereby credit losses are generally the responsibility of Fannie Mae and Freddie Mac, and not the Company. Loans serviced for Ginnie Mae are insured by the FHA, guaranteed by the VA, or insured by other applicable government programs. While the above guarantees and insurance are the responsibility of those parties, the Company is still subject to potential losses related to its servicing of these loans. Those estimated losses are incorporated into the valuation of MSRs. The following table summarizes changes in the MSR assets for the three months ended March 31, 2024 and 2023 (in thousands): For the three months ended March 31, 2024 2023 Fair value, beginning of period $ 4,026,136 $ 4,453,261 Capitalization of MSRs 535,951 525,396 MSR and excess servicing sales (1,383,098) (684,621) Changes in fair value: Due to changes in valuation inputs or assumptions 141,059 (222,915) Due to collection/realization of cash flows/other (128,245) (96,251) Fair value, end of period $ 3,191,803 $ 3,974,870 The following is a summary of the components of the total change in fair value of MSRs as reported in the condensed consolidated statements of operations (in thousands): For the three months ended March 31, 2024 2023 Changes in fair value: Due to changes in valuation inputs and assumptions $ 141,059 $ (222,915) Due to collection/realization of cash flows and other (128,245) (96,251) Net reserves and transaction costs on sales of servicing rights (28,377) (18,121) Changes in fair value of mortgage servicing rights $ (15,563) $ (337,287) During the three months ended March 31, 2024 and 2023, the Company sold MSRs on loans with an aggregate UPB of approximately $87.8 billion and $34.3 billion, respectively, for proceeds of approximately $1.2 billion and $379.1 million, respectively. In addition, during the three months ended March 31, 2024 and 2023, the Company sold excess servicing cash flows on certain agency loans with a total UPB of approximately $19.4 billion and $63.4 billion, respectively, for proceeds of approximately $150.9 million and $305.5 million, respectively. In connection with these sales, the Company recorded a net $28.4 million and $18.1 million, respectively, for its estimated obligation for protection provisions granted to the buyers and transaction costs, which is reflected as part of the change in fair value of MSRs in the condensed consolidated statements of opera tions. The following table summarizes the loan servicing income recognized during the three months ended March 31, 2024 and 2023, respectively (in thousands): For the three months ended March 31, 2024 2023 Contractual servicing fees $ 179,592 $ 214,756 Late, ancillary and other fees 5,110 3,801 Loan servicing income $ 184,702 $ 218,557 The key unobservable inputs used in determining the fair value of the Company’s MSRs were as follows at March 31, 2024 and December 31, 2023, respectively: March 31, December 31, Range Weighted Average Range Weighted Average Discount rates 10.0 % — 16.0 % 11.1 % 10.0 % — 16.0 % 11.1 % Annual prepayment speeds 5.4 % — 21.5 % 8.2 % 5.3 % — 21.9 % 9.6 % Cost of servicing $74 — $111 $85 $74 — $111 $84 The hypothetical effect of adverse changes in these key assumptions would result in a decrease in fair values as follows at March 31, 2024 and December 31, 2023, respectively, (in thousands): March 31, December 31, Discount rate: + 10% adverse change – effect on value $ (116,251) $ (140,727) + 20% adverse change – effect on value (222,615) (269,702) Prepayment speeds: + 10% adverse change – effect on value $ (86,217) $ (124,651) + 20% adverse change – effect on value (166,763) (240,082) Cost of servicing: + 10% adverse change – effect on value $ (25,030) $ (31,869) + 20% adverse change – effect on value (50,060) (63,738) These sensitivities are hypothetical and should be used with caution. As the table demonstrates, the Company’s methodology for estimating the fair value of MSRs is highly sensitive to changes in assumptions. For example, actual prepayment experience may differ, and any difference may have a material effect on MSR fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, in the table above, the effect of a variation in a particular assumption of the fair value of the MSRs is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may indicate higher prepayments; however, this may be partially offset by lower prepayments due to other factors such as a borrower’s diminished opportunity to refinance, or lower discount rates as investors may accept lower returns in a lower interest rate environment), which may magnify or counteract the sensitivities. Thus, any measurement of MSR fair value is limited by the conditions existing and assumptions made as of a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time.

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Representations and Warranties Reserve Loans sold to investors which the Company believes met investor and agency underwriting guidelines at the time of sale may be subject to repurchase by the Company in the event of specific default by the borrower or upon subsequent discovery that underwriting or documentation standards were not explicitly satisfied. The Company may, upon mutual agreement, indemnify the investor against future losses on such loans or be subject to other guaranty requirements and subject to loss. The Company initially records its exposure under such guarantees at estimated fair value upon the sale of the related loan, within "Accounts payable, accrued expenses, and other" as well as within "loan production income," and continues to evaluate its on-going exposures in subsequent perio ds. The reserve is estimated based on the Company’s assessment of its obligations, including expected losses, expected frequency, the overall potential remaining exposure, as well as an estimate for a market participant’s potential readiness to stand by to perform on such obligations. T he Company repu rchased $63.7 million and $58.6 million in UPB of loans during the three months ended March 31, 2024 and 2023, respectively, related to its representations and warranties obligations.

Variable Interest Entities	VARIABLE INTEREST ENTITIES Upon completion of the business combination transaction described in Note 1 , the Company became the managing member of Holdings LLC with 100% of the management and voting power in Holdings LLC. In its capacity as managing member, the Company has the sole authority to make decisions on behalf of Holdings LLC and bind Holdings LLC to signed agreements. Further, Holdings LLC maintains separate capital accounts for its investors as a mechanism for tracking earnings and subsequent distribution rights. Management concluded that the Company is Holdings LLC’s primary beneficiary. As the primary beneficiary, the Company consolidates the results and operations of Holdings LLC for financial reporting purposes under the variable interest entity ( “ VIE ” ) consolidation model. The Company's relationship with Holdings LLC results in no recourse to the general credit of the Company. Holdings LLC and its consolidated subsidiaries represent the Company's sole investment. The Company shares in the income and losses of Holdings LLC in direct proportion to the Company's ownership interest. Further, the Company has no contractual requirement to provide financial support to Holdings LLC. The Company's financial position, performance and cash flows effectively represent those of Holdings LLC and its consolidated subsidiaries as of and for the three months ended March 31, 2024 and 2023. In 2021, UWM began selling some of the mortgage loans that it originates through private label securitization transactions. There have been no loan sales through UWM's private label securitization transactions since 2021. In executing these transactions, the Company sells mortgage loans to a securitization trust for cash and, in some cases, retained interests in the trust. The securitization entities are funded through the issuance of beneficial interests in the securitized assets. The beneficial interests take the form of trust certificates, some of which are sold to investors and some of which may be retained by the Company due to regulatory requirements. Retained beneficial interests consist of a 5% vertical interest in the assets of the securitization trusts, in order to comply with the risk retention requirements applicable to certain of the Company's securitization transactions. The Company has elected the fair value option for subsequently measuring the retained beneficial interests in the securitization trusts, and these investments are presented as “Investment securities at fair value, pledged” in the condensed consolidated balance sheet as of March 31, 2024 and December 31, 2023 . Changes in the fair value of these retained beneficial interests are reported as part of "Other expense (income)" in the condensed consolidated statements of operations. The Company also retains the servicing rights on the securitized mortgage loans. The Company has accounted for these transactions as sales of financial assets. The securitization trusts that purchase the mortgage loans from the Company and securitize those mortgage loans are VIEs, and the Company holds variable interests in certain of these entities. Because the Company does not have the obligation to absorb the VIEs’ losses or the right to receive benefits from the VIEs that could potentially be significant to the VIEs, the Co mpany is not the primary beneficiary of these securitization trusts and is not required to consolidate these VIEs. The Company separately entered into sale and repurchase agreements for a portion of the retained beneficial interests in the securitization trusts, which have been accounted for as borrowings against investment securities. As of March 31, 2024, $106.2 million of the $108.3 million of investment securities at fair value have been pledged as collateral for these borrowings against investment securities. The outstanding principal balance of these borrowings was approximately $94.1 million with remaining maturities ranging from approximately one

Non-controlling Interests	NON-CONTROLLING INTERESTS The non-controlling interest balance represents the economic interest in Holdings LLC held by SFS Corp. The following table summarizes the ownership of units in Holdings LLC as of: March 31, 2024 December 31, 2023 Common Units Ownership Percentage Common Units Ownership Percentage UWM Holdings Corporation ownership of Class A Common Units 94,945,635 5.95 % 93,654,269 5.87 % SFS Corp. ownership of Class B Common Units 1,502,069,787 94.05 % 1,502,069,787 94.13 % Balance at end of period 1,597,015,422 100.00 % 1,595,724,056 100.0 % The non-controlling interest holder has the right to exchange Class B Common Units, together with a corresponding number of shares of our Class D common stock or Class C common stock (together referred to as “Stapled Interests”), for, at the Company's option, (i) shares of the Company's Class B common stock or Class A common stock or (ii) cash from a substantially concurrent public offering or private sale (based on the price of the Company's Class A common stock). As such, future exchanges of Stapled Interests by the non-controlling interest holder will result in a change in ownership and reduce or increase the amount re corded as non-controlling interest and increase or decrease additional paid-in-capital or retained earnings when Holdings LLC has positive or negative net assets, respectively. As of March 31, 2024, SFS Corp. has not exchanged any Stapled Interests. During the three months ended March 31, 2024, the Company issued 1,291,366 shares of Class A common stock, net of withholdings, which primarily related to the vesting of RSUs under its stock-based compensation plan. During the three months ended March 31, 2023 , the Company issued 525,997 shares of Class A common stock which primarily related to the vesting of RSUs under its stock-based compensation plan. This resulted in an equivalent increase in the number of Class A Common Units of Holdings LLC held by the Company, and a r

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined under U.S. GAAP as the price that would be received if an asset were sold or the price that would be paid to transfer a liability in an orderly transaction between willing market participants at the measurement date. Required disclosures include classification of fair value measurements within a three-level hierarchy (Level 1, Level 2 and Level 3). Classification of a fair value measurement within the hierarchy is dependent on the classification and significance of the inputs used to determine the fair value measurement. Observable inputs are those that are observed, implied from, or corroborated with externally available market information. Unobservable inputs represent the Company’s estimates of market participants’ assumptions. Fair value measurements are classified in the following manner: Level 1 —Valuation is based on quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 —Valuation is based on either observable prices for identical assets or liabilities in inactive markets, observable prices for similar assets or liabilities, or other inputs that are derived directly from, or through correlation to, observable market data at the measurement date. Level 3 —Valuation is based on the Company’s or others’ models using significant unobservable assumptions at the measurement date that a market participant would use. In determining fair value measurements, the Company uses observable inputs whenever possible. The level of a fair value m easurement within the hierarchy is dependent on the lowest level of input that has a significant impact on the measurement as a whole. If quoted market prices are available at the measurement date or are available for similar instruments, such prices are used in the measurements. If observable market data is not available at the measurement date, judgement is required to measure fair value. The following is a description of measurement techniques for items recorded at fair value on a recurring basis. There were no material items recorded at fair value on a nonrecurring basis as of March 31, 2024 or December 31, 2023. Mortgage loans at fair value : The Company has elected the fair value option for mortgage loans. Accordingly, the fair values of mortgage loans are based on valuation models that use the market price for similar loans sold in the secondary market. As these prices are derived from market observable inputs, they are categorized as Level 2. IRLCs : The Company's interest rate lock commitments are derivative instruments that are recorded at fair value based on valuation models that use the market price for similar loans sold in the secondary market. The IRLCs are then subject to an estimated loan funding probability, or “pullthrough rate.” Given the significant and unobservable nature of the pullthrough rate assumption, IRLC fair value measurements are classified as Level 3. MSRs : The fair value of MSRs is determined using a valuation model that calculates the present value of estimated future net servicing cash flows. The model includes estimates of prepayment speeds, discount rate, cost to service, float earnings, contractual servicing fee income, and ancillary income and late fees, among others. These estimates are supported by market and economic data collected from various outside sources. These fair value measurements are classified as Level 3. FLSCs : The Company enters into forward loan sales commitments to sell certain mortgage loans which are recorded at fair value based on valuation models. The Company’s expectation of the amount of its interest rate lock commitments that will ultimately close is a factor in determining the position. The valuation models utilize the fair value of related mortgage loans determined using observable market data, and therefore, the fair value measurements of these commitments are categorized as Level 2. Investment securities at fair value, pledged : The Company occasionally sells mortgage loans that it originates through private label securitization transactions. In executing these securitizations, the Company sells mortgage loans to a securitization trust for cash and, in some cases, retained interests in the trust. The Company has elected the fair value option for subsequently measuring the retained beneficial interests in the securitization trusts. The fair value of these investment securities is primarily based on observable market data and therefore categorized as Level 2. Public and Private Warrants : The fair value of Public Warrants is based on the price of trades of these securities in active markets and therefore categorized as Level 1. The fair value of the Private Warrants is based on observable market data and therefore categorized as Level 2. Financial Instruments - Assets and Liabilities Measured at Fair Value on a Recurring Basis The following are the major categories of financial assets and liabilities measured at fair value on a recurring basis (in thousands): March 31, 2024 Description Level 1 Level 2 Level 3 Total Assets: Mortgage loans at fair value $ — $ 7,338,135 $ — $ 7,338,135 IRLCs — — 25,359 25,359 FLSCs — 8,691 — 8,691 Investment securities at fair value, pledged — 108,323 — 108,323 Mortgage servicing rights — — 3,191,803 3,191,803 Total assets $ — $ 7,455,149 $ 3,217,162 $ 10,672,311 Liabilities: IRLCs $ — $ — $ 5,443 $ 5,443 FLSCs — 21,475 — 21,475 Public and Private Warrants 3,081 4,066 — 7,147 Total liabilities $ 3,081 $ 25,541 $ 5,443 $ 34,065 December 31, 2023 Description Level 1 Level 2 Level 3 Total Assets: Mortgage loans at fair value $ — $ 5,449,884 $ — $ 5,449,884 IRLCs — — 29,623 29,623 FLSCs — 3,396 — 3,396 Investment securities at fair value, pledged — 110,352 — 110,352 Mortgage servicing rights — — 4,026,136 4,026,136 Total assets $ — $ 5,563,632 $ 4,055,759 $ 9,619,391 Liabilities: IRLCs $ — $ — $ 2,933 $ 2,933 FLSCs — 37,848 — 37,848 Public and Private warrants 3,078 4,755 — 7,833 Total liabilities $ 3,078 $ 42,603 $ 2,933 $ 48,614 The following table presents quantitative information about the inputs used in recurring Level 3 fair value financial instruments and the fair value measurements for IRLCs: Unobservable Input - IRLCs March 31, 2024 December 31, 2023 Pullthrough rate (weighted avg.) 79 % 76 % Refer to Note 5 - Mortgage Servicing Rights for further information on the unobservable inputs used in measuring the fair value of the Company’s MSRs and for the roll-forward of MSRs for the three months ended March 31, 2024. Level 3 Issuances and Transfers The Company enters into IRLCs which are considered derivatives. If the contract converts to a loan, the implied value, which is solely based upon interest rate changes, is incorporated in the basis of the fair value of the loan. If the IRLC does not convert to a loan, the basis is reduced to zero as the contract has no continuing value. The Company does not track the basis of the individual IRLCs that convert to a loan, as that amount has no relevance to the presented condensed consolidated financial statements. Other Financial Instruments The following table presents the carrying amounts and estimated fair value of the Company's financial liabilities that are not measured at fair value on a recurring or nonrecurring basis (in thousands): March 31, 2024 December 31, 2023 Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value 2025 Senior Notes, due 11/15/25 $ 796,441 $ 793,456 $ 795,894 $ 795,144 2029 Senior Notes, due 4/15/29 695,589 662,473 695,370 662,396 2027 Senior Notes, due 6/15/27 497,220 486,595 497,003 490,825 $ 1,989,250 $ 1,942,524 $ 1,988,267 $ 1,948,365 The fair value of the 2025, 2029 and 2027 Senior Notes was estimated using Level 2 inputs, including observable trading information from independent sources. Due to their nature and respective terms (including the variable interest rates on warehouse and other lines of credit and borrowings against investment securities) , the carrying value of cash and cash equivalents, receivables, payables, borrowings against investment securities and warehouse and other lines of credit approximate their fair values as of March 31, 2024 and December 31, 2023, respectively.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE The Company has two classes of economic shares authorized - Class A and Class B common stock. The Company applies the two-class method for calculating earnings per share for Class A common stock and Class B common stock. In applying the two-class method, the Company allocates undistributed earnings equally on a per share basis between Class A and Class B common stock. According to the Company’s certificate of incorporation, the holders of the Class A and Class B common stock are entitled to participate in earnings equally on a per-share basis, as if all shares of common stock were of a single class, and in such dividends as may be declared by the Board of Directors. RSUs awarded as part of the Company’s stock compensation plan are included in weighted-average Class A shares outstanding in the calculation of basic earnings per share once the RSUs are vested and shares are issued. Basic earnings (loss) per share of Class A common stock and Class B common stock is computed by dividing net income (loss) attributable to UWM Holdings Corporation by the weighted-average number of shares of Class A common stock and Class B common stock outstanding during the period. Diluted earnings (loss) per share of Class A common stock and Class B common stock is computed by dividing net income (loss) by the weighted-average number of shares of Class A common stock or Class B common stock, respectively, outstanding adjusted to give effect to potentially dilutive securities. See Note 11 , Non-Controlling Interests for a description of the Stapled Interests. Refer to Note 1 - Organization, Basis of Presentation and Summary of Significant Accounting Policies - for additional information related to the Company's capital structure. There was no Class B common stock outstanding as of March 31, 2024 or March 31, 2023. The following table sets forth the calculation of basic and diluted earnings (loss) per share for the periods ended March 31, 2024 and 2023 (in thousands, except shares and per share amounts): For the three months ended March 31, 2024 2023 Net income (loss) $ 180,531 $ (138,613) Net income (loss) attributable to non-controlling interests 171,801 (126,672) Net income (loss) attributable to UWMC 8,730 (11,941) Numerator: Net income (loss) attributable to Class A common shareholders $ 8,730 $ (11,941) Net income (loss) attributable to Class A common shareholders - diluted $ 142,860 $ (11,941) Denominator: Weighted average shares of Class A common stock outstanding - basic 94,365,991 92,920,794 Weighted average shares of Class A common stock outstanding - diluted 1,598,647,205 92,920,794 Earnings (loss) per share of Class A common stock outstanding - basic $ 0.09 $ (0.13) Earnings (loss) per share of Class A common stock outstanding - diluted $ 0.09 $ (0.13) For purposes of calculating diluted earnings per share, it was assumed that the 1,502,069,787 shares of Class D common stock were exchanged for Class B common stock and converted to Class A common stock under the if-converted method , and it was determined that the conversion would be dilutive for the three months ended March 31, 2024 and anti-dilutive for the three months ended March 31, 2023. Under the if-converted method, all of the Company's net income (loss) for the applicable periods is attributable to Class A common shareholders. The net income (loss) of the Company under the if-converted method is calculated including an estimated income tax provision which is determined using a blended statutory effective tax rate. The Public and Private Warrants were not in the money and the triggering events for the issuance of earn-out shares were not met during the three months ended March 31, 2024 and 2023. Therefore, these potentially dilutive securities were excluded from the computation of diluted earnings per share. Unvested RSUs have been considered in the calculations of diluted earnings per share for the three months ended March 31, 2024 and 2023 using the treasury stock method and the impact was either anti-dilutive or immaterial.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Orga nization UWM Holdings Corporation, through its consolidated subsidiaries (collectively, the “Company”), engages in the origination, sale and servicing of residential mortgage loans. The Company is organized in Delaware but based in Michigan, and originates and services loans throughout the U.S. The Company is approved as a Title II, non-supervised direct endorsement mortgagee with the U.S. Department of Housing and Urban Development (or “HUD”). In addition, the Company is an approved issuer with the Government National Mortgage Association (or “Ginnie Mae”), as well as an approved seller and servicer with the Federal National Mortgage Association (or “Fannie Mae”) and the Federal Home Loan Mortgage Corporation (or “Freddie Mac”). The Company (f/k/a Gores Holdings IV, Inc.) was incorporated in Delaware on June 12, 2019. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. On September 22, 2020, the Company entered into a Business Combination Agreement (the “Business Combination Agreement”) by and among the Company, SFS Holding Corp., a Michigan corporation (“SFS Corp.”), United Wholesale Mortgage, LLC, a Michigan limited liability company (“UWM”), and UWM Holdings, LLC, a newly formed Delaware limited liability company (“Holdings LLC” and, together with UWM, the “UWM Entities”). The business combination with the UWM Entities closed on January 21, 2021. Prior to the closing of the business combination with the UWM Entities, SFS Corp. was the sole member of UWM, which had one unit authorized, issued and outstanding. On January 21, 2021, SFS Corp. contributed its equity interest in UWM to Holdings LLC and adopted the Amended and Restated Operating Agreement to admit Holdings LLC as UWM's sole member and its manager. Upon completion of the business combination transaction, (i) Holdings LLC issued approximately 6% of its units (Class A Common Units) to the Company, (ii) SFS Corp. retained approximately 94% of the units (Class B Common Units) in Holdings LLC and accordingly retained approximately 94% of the economic ownership interest of the combined company and (iii) Holdings LLC became a consolidated subsidiary of the Company, as the Company is the sole managing member of Holdings LLC. The economic interest in Holdings LLC owned by SFS Corp. is presented as a non-controlling interest in these condensed consolidated financial statements. See Note 11 - Non-Controlling Interests for further information. Following the consummation of the transactions contemplated by the Business Combination Agreement, the Company is organized in an “Up-C” structure in which UWM (the operating subsidiary) is held directly by Holdings LLC, and the Company’s only material direct asset consists of Class A Common Units in Holdings LLC. The Company’s current capital structure authorizes Class A common stock, Class B common stock, Class C common stock and Class D common stock. The Class A common stock and Class C common stock each provide holders with one vote on all matters submitted to a vote of stockholders, and the Class B common stock and Class D common stock each provide holders with 10 votes on all matters submitted to a vote of stockholders. The holders of Class C common stock and Class D common stock do not have any of the economic rights (including rights to dividends and distributions upon liquidation) provided to holders of Class A common stock and Class B common stock. Each Holdings LLC Class B Common Unit held by SFS Corp. may be exchanged at the option of the Company, along with its stapled share of Class D common stock, for either, (a) cash or (b) one share of the Company’s Class B common stock. Each share of Class B common stock is convertible into one share of Class A common stock upon the transfer or assignment of such share from SFS Corp. to a non-affiliated third-party. See Note 11 - Non-Controlling Interests for further information. Pursuant to the Business Combination Agreement, SFS Corp. is entitled to receive an aggregate of up to 90,761,687 earn-out shares in the form of Class B Common Units in Holdings LLC and Class D common shares upon attainment of certain stock price targets prior to January 2026. There are four different triggering events that affect the number of earn-out shares that will be issued based upon the per share price of Class A common stock ranging from $13.00 to $19.00 per share. The Company accounts for the potential earn-out shares as a component of stockholders’ equity in accordance with the applicable guidance in U.S. GAAP. See Note 17 - Earnings Per Share for further information. Upon completion of the business combination transaction, the directors and officers of Gores Holdings IV, Inc. (the “Gores Directors and Officers”) resigned, the Company appointed new directors to its Board, and certain officers of UWM became officers of the Company. Pursuant to the Business Combination Agreement, the Company has potential indemnification obligations to the Gores Directors and Officers for costs or losses incurred prior to or after the closing of the business combination transaction that arose by reason of the fact that he or she is or was a director or officer of Gores Holdings IV, Inc . The Gores Directors and Officers have been named as defendants in class action suits in Delaware Chancery Court in which it is alleged that they breached their fiduciary duties to shareholders of Gores Holdings, IV. Pursuant to its obligations under the Business Combination Agreement, to the extent that it is determined that the Gores Directors and Officers are entitled to indemnification, the Company is obligated to indemnify them in connection with these lawsuits. The Company has insurance which it believes will cover any material liability that could arise pursuant to its indemnification obligations to the Gores Directors and Officers. This insurance includes two separate towers of coverage with limits in excess of the Company's current estimate of any reasonably possible liability, and a deductible of $20.5 million.
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The condensed consolidated financial statements are unaudited and presented in U.S. dollars. They have been prepared in accordance with U.S. GAAP pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In our opinion, these condensed consolidated financial statements include all normal and recurring adjustments considered necessary for a fair statement of our results of operations, financial position and cash flows for the periods presented. However, our results of operations for any interim period are not necessarily indicative of the results that may be expected for a full fiscal year or for any other future period.
Use of Estimates	Use of Estimates
Loans Eligible for Repurchase from Ginnie Mae	Loans Eligible for Repurchase from Ginnie Mae For certain loans sold to Ginnie Mae, the Company as the servicer has the unilateral right to repurchase any individual loan in a Ginnie Mae pool if that loan meets defined criteria (generally loans that are more than 90 days past due). When the Company has the unilateral right to repurchase the delinquent loans, the previously sold assets are required to be re-recognized on the condensed consolidated balance sheets as assets and corresponding liabilities at the loan's unpaid principal balance, regardless of the Company’s intent to exercise its option to repurchase. The recognition of previously sold loans does not impact the accounting for the previously recognized mortgage servicing rights (or "MSRs").
Income Taxes And Tax Receivable Agreement	Income Taxes The Company accounts for income taxes during interim periods by applying an estimated annual effective tax rate to year-to-date earnings (loss) before income taxes to compute the year-to-date tax expense (or benefit). At the end of each interim period, the Company estimates the effective tax rate expected to be applicable for the full fiscal year, adjusted for discrete items, if any, that arise during the period. See Note 15 – Income Taxes for further information. Tax Receivable Agreement The Company has entered into a Tax Receivable Agreement ("TRA") with SFS Corp. that will obligate the Company to make payments to SFS Corp. of 85% of the amount of cash savings, if any, in federal, state and local income tax that the Company actually realizes as a result of (i) certain increases in tax basis resulting from exchanges of Holdings LLC common units; (ii) imputed interest deemed to be paid by the Company as a result of payments it makes under the tax receivable agreement; (iii) certain increases in tax basis resulting from payments the Company makes under the tax receivable agreement; and (iv) disproportionate allocations (if any) of tax benefits to the Company which arise from, among other things, the sale of certain assets as a result of taxable income allocation rules in the United States. The Company will retain the benefit of the remaining 15% of these tax savings.

Public and Private Warrants	Public and Private Warrants As part of Gores Holdings IV, Inc.'s initial public offering ("IPO") in January 2020, Gores Holdings IV, Inc. issued to third party investors 42.5 million units, consisting of one share of Class A common stock of Gores Holdings IV, Inc. and one-fourth of one warrant, at a price of $10.00 per unit. Each whole warrant entitles the holder to purchase one share of Class A common stock at an exercise price of $11.50 per share (the “Public Warrants”). Simultaneously with the closing of the IPO, Gores Holdings IV, Inc. completed the private sale of 5.25 million warrants to Gores Holdings IV, Inc.'s sponsor at a purchase price of $2.00 per warrant (the “Private Warrants”). Each Private Warrant allows the sponsor to purchase one share of Class A common stock at $11.50 per share. Upon the closing of the business combination transaction, the Company had 10,624,987 Public Warrants and 5,250,000 Private Warrants outstanding.

This guidance requires all lessees in a lease with a lessor under common control to amortize leasehold improvements over the useful life of the common control group and provides new guidance for recognizing a transfer of assets between entities under common control as an adjustment to equity when the lessee no longer controls the use of the underlying asset. There was no impact on the Company's condensed consolidated financial statements from adopting this standard effective the fiscal year beginning January 1, 2024. Accounting Standards Issued but Not Yet Effective In November 2023, the FASB issued ASU 2023-7, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires enhanced disclosure of significant segment expenses on an annual and interim basis. The ASU is effective on a retrospective basis for annual periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted. The Company will include the required disclosures in its consolidated financial statements once adopted. In December 2023, the FASB issued ASU 2023-9 , Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024, and early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance.
