Accounting Policies [Abstract]
Description of Business	Description of Business Marcus & Millichap, Inc. (the “Company,” “Marcus & Millichap,” or “MMI”), a Delaware corporation, is a real estate services firm specializing in commercial real estate investment sales, financing services, research and advisory services. As of June 30, 2026, MMI operates over 80 offices in the United States and Canada through its wholly-owned subsidiaries, including the operations of Marcus & Millichap Capital Corporation.
Reorganization and Initial Public Offering	Reorganization and Initial Public Offering Marcus & Millichap, Inc. was formed in June 2013 in preparation for the spin-off of Marcus & Millichap Real Estate Investment Services, Inc. (“MMREIS”), the real estate investment services business of the Marcus & Millichap Company (“MMC”). Our initial public offering (“IPO”) was completed in November 2013. In connection with our IPO, the shareholders of MMREIS contributed their shares of MMREIS to MMI in exchange for common stock of MMI.
Basis of Presentation	Basis of Presentation The financial information presented in the accompanying unaudited condensed consolidated financial statements has been prepared in accordance with rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for Quarterly Reports on Form 10-Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements and notes include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the condensed consolidated financial position, results of operations and cash flows for the periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto, including the Company’s accounting policies for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K filed on February 26, 2026 with the SEC. The results of the three and six months ended June 30, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026, for other interim periods or for future years.
Reclassifications	The Company reclassified certain items previously included within prepaid expenses to prepaid expenses and other assets, current in the December 31, 2025 consolidated balance sheet to conform with current period presentation.
Consolidation	Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the 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, the related disclosures 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.
Concentration of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk principally consist of cash, cash equivalents, and restricted cash, investments in marketable debt securities, available-for-sale, investments in strategic alliance partners (included under prepaid expenses and other assets, current and other assets, non-current), security deposits (included under other assets, non-current), and commissions receivable, net. Cash, cash equivalents, and restricted cash are placed with high-credit quality financial institutions and invested in high-credit quality money market funds and commercial paper. Concentrations and ratings of investments in marketable debt securities, available-for-sale are limited by the approved investment policy. To reduce its credit risk, the Company monitors the credit standing of the financial institutions and money market funds that represent amounts recorded as cash, cash equivalents, and restricted cash. The Company historically has not experienced any significant losses related to cash, cash equivalents, and restricted cash. In September 2021, the Company entered into a strategic alliance (“Strategic Alliance”) with M&T Realty Capital Corporation (“MTRCC”) pursuant to which the Company provides loan opportunities that may be funded through MTRCC’s Delegated Underwriting and Servicing Agreement (“DUS Agreement”) with the Federal National Mortgage Association (“Fannie Mae”) that requires MTRCC to guarantee a portion of each loan funded. On a loan-by-loan basis, the Company, at its option, can indemnify a portion of MTRCC’s guarantee obligation of loan opportunities presented to and closed by MTRCC through the DUS Agreement. The Company manages and limits the concentration of risk related to the guarantees assumed by monitoring the underlying property type, geographic location, credit of the borrowers, underlying debt service coverage, and loan to value ratios. The Company derives its revenue from a broad range of real estate investors, owners, and users in the United States and Canada, none of which individually represents a significant concentration of credit risk. The Company maintains allowances, as needed, for estimated credit losses based on management’s assessment of the likelihood of collection. For each of the three and six months ended June 30, 2026 and 2025, no transaction represented 10% or more of total revenue. Further, while one or more transactions may represent 10% or more of commissions receivable at any reporting date, amounts due for brokerage and financing transactions are typically collected within 10 days of settlement and, therefore, do not expose the Company to significant credit risk.
Revenue Recognition	Revenue Recognition The Company generates real estate brokerage commissions by acting as a broker for real estate owners or investors seeking to buy or sell interests in commercial properties and generates financing fees from securing financing on purchase transactions, from refinancing its clients’ existing mortgage debt and other ancillary fees associated with financing activities, including, but not limited to, debt and equity advisory services, loan sales, due diligence services, loan guarantee fees, loan performance fees and other consulting services. Real Estate Brokerage Commissions Contracts for representing buyers and sellers of real estate are negotiated on a transaction-by-transaction basis. The consideration associated with the successful outcome remains constrained until the completion of a transaction which happens at the close of escrow. At that time, the Company's performance is complete, and the Company recognizes revenue related to the transaction. Financing Fees Contracts for representing potential borrowers are negotiated on a transaction-by-transaction basis. The consideration associated with the successful outcome remains constrained until the completion of a transaction which happens at the time the loan closes. At that time, the Company recognizes revenue related to the transaction. The Company’s fee arrangements, with an exception for guarantee obligations, do not include terms or conditions that require the Company to perform any service or fulfill any obligation once the loan closes. Loan Performance Fees - For loans originated through the Strategic Alliance with MTRCC, the Company receives variable consideration in the form of loan performance fees based on a portion of the servicing fees expected to be received by MTRCC under the servicing contract for servicing the loan. As the Company is not obligated to perform any servicing functions and has no further obligations related to the transaction giving rise to the loan performance fees, the estimated value of the loan performance fees to be received is recorded at the time the loan closes and are collected over the estimated term of the related loan. Any changes in the estimate of loan performance fees to be received are recorded in revenue in the period the estimate changes. Guarantee Obligations - For certain loans originated through the Strategic Alliance with MTRCC, the Company may agree, at its option, to indemnify MTRCC for a portion of MTRCC’s obligations for loans sold to Fannie Mae. For these loans, the Company allocates a portion of the transaction price and records a loan guarantee obligation based on its fair value. Revenue for this stand-ready obligation is recorded on a straight-line basis over the term of the estimated guarantee period and is recorded in financing fees in the condensed consolidated statements of operations. The guarantee obligation is capped at 16.70% of any unpaid principal balance in excess of the value of the collateral securing such loan. For these loans, the Company is required to pledge cash in a restricted bank account in support of the guarantee obligation. The Company records an allowance for estimated losses related to the loans subject to the guarantee considering the risk characteristics of the loan, the loan's risk rating, historical loss experience, potential adverse situations affecting individual loans and other forecasted information as appropriate. Other Revenue Other revenue includes fees generated from leasing, consulting and advisory services, as well as fees from other ancillary services, and such fees are recognized when services are provided, or upon closing of the transaction or when the Company has no further performance obligations.
New Accounting Pronouncements	New Accounting Pronouncements Pending Adoption In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). ASU 2023-06 was issued in response to the SEC’s final amendments in Release No. 33-10532, Disclosure Update and Simplification that updated and simplified disclosure requirements that the SEC believed were duplicative, overlapping, or outdated, and to align the requirements in the FASB Accounting Standards Codification (“Codification”) with the SEC’s disclosure requirements. The effective date for each amendment in ASU 2023-06 will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K by June 30, 2027, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. The Company does not expect the adoption of ASU 2023-06 to have a material impact on its condensed consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). The new guidance is intended to provide investors enhanced disclosures and requires public entities to disaggregate key expense types. The update is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The disclosure updates are required to be applied prospectively with the option for retrospective application. While the adoption is not expected to have an impact on the Company's condensed consolidated financial statements, it is expected to result in incremental disclosures within the footnotes to its condensed consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) (“ASU 2025-06”), to update guidance on accounting for internal-use software. The amendments modernize guidance to consider different methods of software development, updating the requirements for capitalization of software costs. ASU 2025-06 is effective for annual reporting periods beginning after December 15, 2027, with early adoption permitted. The new requirements may be applied on a prospective, retrospective, or modified transition approach. The Company is evaluating the impact this ASU will have on its condensed consolidated financial statements and related disclosures. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”), which clarifies the guidance in Topic 270 to improve the consistency of interim financial reporting. The ASU provides a comprehensive list of required interim disclosures and introduces a disclosure principle requiring entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this ASU will have on its condensed consolidated financial statements.
