Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and all intercompany balances and transactions have been eliminated. These condensed consolidated financial statements and notes thereto are unaudited, and as permitted by the interim reporting rules and regulations set forth by the SEC, exclude certain financial information and note disclosures normally included in annual audited financial statements prepared in accordance with U.S. GAAP. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K. The condensed consolidated financial statements reflect all material adjustments of a normal recurring nature that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements and related disclosures in accordance 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 revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates and the assumptions underlying these estimates are reviewed periodically, and the effects of revisions are reflected in the period in which they are determined to be necessary. In preparing the condensed consolidated financial statements, management makes certain estimates regarding the measurement of amounts due pursuant to the tax receivable agreement, measurement and timing of revenue recognition, assumptions used in the provision for income taxes, measurement of equity-based compensation, expected insurance reimbursements related to litigation costs, fair value measurement and impairment assessment of goodwill and intangible assets, fair value measurement of financial instruments, and other matters that affect the reported amounts and disclosures of contingencies in the condensed consolidated financial statements and notes thereto.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents include cash held at banks, including interest-bearing money market accounts, and any highly liquid investments with original maturities of three months or less from the date of purchase. Cash account balances often exceed federally insured limits. Restricted cash represents cash that is not readily available for general purpose cash needs. As of September 30, 2026 and December 31, 2025, the Company had restricted cash of $1.1 million maintained as collateral for letters of credit related to certain office leases. As of September 30, 2026 and December 31, 2025, the Company held no cash equivalents. The sum of Cash and cash equivalents and Restricted cash on the Condensed Consolidated Statements of Financial Condition corresponds to the total cash, cash equivalents, and restricted cash presented on the Condensed Consolidated Statements of Cash Flows.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is recorded for the excess of the fair value of consideration transferred over the fair value of identifiable net assets, including other intangibles, acquired at the time of an acquisition. Goodwill is periodically reviewed, and tested at least annually, for impairment, and when certain events or circumstances indicate impairment may exist. Goodwill is tested for impairment at the reporting unit level. A reporting unit is a component of an operating segment for which discrete financial information is available that is regularly reviewed by management. Intangible assets are derived from customer relationships, trade names and trademarks. Identifiable finite-lived intangible assets are amortized on a straight-line basis over the applicable estimated useful life, reflecting the average time over which such intangible assets are expected to contribute to cash flow. The Company tests intangible assets for impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable.
Business Combinations	Business Combinations The Company accounts for business combinations under the acquisition method of accounting, which requires an allocation of the total consideration paid for the acquired business to the identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. Any excess of fair value of total consideration paid over the fair value of the net assets acquired is recognized as goodwill. Consideration contingent on future events is evaluated to determine whether it represents consideration transferred for the acquired business or compensation for post-combination services. Contingent consideration liabilities are recognized at the acquisition date fair value and revalued at each reporting period. Contingent compensation expense is accrued over the requisite service period. Based on the timing of the close of a transaction, certain valuation calculations may be considered preliminary due to information that may subsequently become available, and values assigned to acquired assets and liabilities could change. The acquisition date fair value of certain assets and liabilities, including intangible assets acquired and related expected life calculations, may be provisional and subject to revision within one year of the acquisition date. Any changes in the fair values of the assets acquired and liabilities assumed during the measurement period may result in adjustments to goodwill.
Consolidation	Consolidation The Company’s policy is to consolidate entities in which the Company has a controlling financial interest and variable interest entities where the Company is deemed to be the primary beneficiary. The Company is deemed to be the primary beneficiary of a variable interest entity (“VIE”) when it has both (i) the power to make the decisions that most significantly affect the economic performance of the VIE and (ii) the obligation to absorb significant losses or the right to receive benefits that could potentially be significant to the VIE. PWP is the primary beneficiary of and consolidates PWP OpCo, a VIE. As of September 30, 2026 and December 31, 2025, the net assets of PWP OpCo were $324.8 million and $235.3 million, respectively. As of September 30, 2026 and December 31, 2025, the Company did not consolidate any VIEs other than PWP OpCo.
Redeemable Non-Controlling Interests	Redeemable Non-Controlling Interests For entities that are consolidated but not 100% owned, a portion of the income (loss) and equity is allocated to holders of the non-controlling interest. Profits and losses of PWP OpCo are allocated to the non-controlling interests in proportion to their ownership interest regardless of their basis. Redeemable non-controlling interests are presented within temporary equity on the Condensed Consolidated Statements of Financial Condition at the higher of: (i) their redemption value as of the reporting date, which corresponds to the price of the Company’s Class A common stock, or (ii) their measurement pursuant to Accounting Standards Codification (“ASC” or the “Codification”) Topic 810, Consolidation. Changes in the current redemption value are recorded to Additional paid-in capital immediately as they occur. The magnitude of these changes may exceed the available balance of Additional paid-in capital, resulting in subsequent equity transactions being recorded to Accumulated deficit. As of September 30, 2025, $28.0 million was recorded to Accumulated deficit, driven by increases in the redemption value of Redeemable non-controlling interests. During the year ended December 31, 2025, equity transactions offset this cumulative amount and restored an Additional paid-in capital balance. Accordingly, no such amounts were recorded to Accumulated deficit as of December 31, 2025 or September 30, 2026. When the Company has an unconditional obligation to purchase the Redeemable non-controlling interests for cash, the mandatorily redeemable interests are reclassified from temporary equity to a liability with changes in fair value recorded to Other income (expense) on the Condensed Consolidated Statements of Operations. As of September 30, 2026, there were no non-controlling interests considered mandatorily redeemable.
Equity-Based Compensation	Equity-Based Compensation Equity-based compensation relates to equity-based awards granted to employees and partners of the Company. Equity-based compensation expense is recognized over the requisite vesting period or requisite service period in an amount equal to the grant date fair value (for equity-classified awards) or the settlement fair value (for liability-classified awards). Equity-based compensation expense for employees and partners is included in Equity-based compensation on the Condensed Consolidated Statements of Operations and equity-based compensation expense for non-employees is included in Professional fees on the Condensed Consolidated Statements of Operations. The Company accounts for forfeitures of awards as they occur rather than applying an estimated forfeiture rate. For an award with service-only conditions that has a graded vesting schedule, the Company recognizes the compensation cost for the entire award on a straight-line basis over the requisite service period, ensuring that the amount recognized is at least equal to the vested portion of the award at each reporting date.
Foreign Currencies	Foreign Currencies In the normal course of business, the Company and its subsidiaries may enter into transactions denominated in a non-functional currency. The Company recognized net foreign exchange gains (losses) arising from such transactions of $(0.3) million and $0.5 million during the three and nine months ended September 30, 2026, respectively, and $1.5 million and $(3.0) million for the three and nine months ended September 30, 2025, respectively, which are included in Other income (expense) on the Condensed Consolidated Statements of Operations. In addition, the Company consolidates its foreign subsidiaries that have non-U.S. dollar functional currencies. Non-U.S. dollar denominated assets and liabilities are translated to U.S. dollars at the exchange rate prevailing at the reporting date and profit and loss activity is generally translated using the average exchange rate throughout the period. Cumulative translation adjustments arising from the translation of non-U.S. dollar denominated operations are included as a component of Accumulated other comprehensive income (loss) on the Condensed Consolidated Statements of Changes in Equity and Redeemable Non-Controlling Interests.
Recently Adopted and Future Adoption of Accounting Pronouncements	Recently Adopted Accounting Pronouncements Credit Losses—Effective January 1, 2026, the Company prospectively adopted Accounting Standards Update 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), which amends the guidance in ASC Topic 326, Financial Instruments—Credit Losses to simplify the process for preparing the estimate of expected credit losses. The Company elected the practical expedient provided under ASU 2025-05 that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. The adoption did not have a material impact on the Company’s condensed consolidated financial statements. Future Adoption of Accounting Pronouncements Expense Disaggregation—In November 2024, the FASB issued Accounting Standards Update 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”), which amends the guidance in ASC Topic 220, Income Statement—Reporting Comprehensive Income, to improve the transparency of expense disclosures by requiring more detailed information about the types of expenses in commonly presented expense captions. The amendments in ASU 2024-03 are effective for the Company beginning with the annual period ended December 31, 2027. The amendments are to be applied prospectively with both retrospective application and early adoption permitted. The Company does not expect the adoption of ASU 2024-03 to have a material impact on the consolidated financial statements. Internal-Use Software—In September 2025, the FASB issued Accounting Standards Update 2025-06, Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”), which amends the guidance in ASC Subtopic 350-40, Intangibles—Goodwill and Other—Internal-Use Software, to clarify and increase the operability of applying the internal-use software guidance to software costs incurred in an iterative development environment. The amendments in ASU 2025-06 are effective for the Company beginning with the interim periods within the annual period ended December 31, 2028. The amendments can be applied prospectively, retrospectively, or on a modified transition approach based on the status of the project and whether software costs were capitalized before the date of adoption. Early adoption is permitted. The Company does not expect the adoption of ASU 2025-06 to have a material impact on the consolidated financial statements.
Revenue Recognition	As of September 30, 2026 and December 31, 2025, the Company recorded $0.3 million and $1.0 million, respectively, for contract liabilities which are presented within Accounts payable, accrued expenses and other liabilities on the Condensed Consolidated Statements of Financial Condition.
