| Related Party Transactions [Abstract] | |
| Related Party Transactions Disclosure [Text Block] | Related Party Transactions The Company engages in certain related party transactions in the normal course of business at arm's length. Nephila Fund Management The Company provides investment and insurance management services through Nephila Holdings Ltd. (together with its subsidiaries, Nephila). Nephila serves as the investment manager to several Bermuda based private funds (the Nephila Funds). To provide access for the Nephila Funds to a variety of insurance-linked securities in the property catastrophe, climate, and specialty insurance markets, Nephila also acts as an insurance manager to certain Bermuda licensed reinsurers and as the managing agent to Lloyd's Syndicates 2357, 2358, and 2359 (collectively, the Nephila Reinsurers). Neither the Nephila Funds nor the Nephila Reinsurers are consolidated by the Company. Nephila receives management fees for investment and insurance management services based on either the net asset value of the accounts managed or gross premium volume for the underlying risks to which the investors subscribed. For certain funds, Nephila may also receive performance fees based on their annual performance. For the three months ended March 31, 2026 and 2025, total fund management revenues attributed to unconsolidated entities managed by Nephila were $40.5 million and $25.5 million, respectively. Fronting The Company's fronting activities, which are provided through the Company's Markel Insurance operations and program services operations, include programs with the Nephila Reinsurers through which the Company writes insurance policies that are fully ceded to the Nephila Reinsurers in exchange for fronting fees. Through these programs, Nephila utilizes certain of the Company's licensed insurance companies to write a portion of its portfolio of U.S. catastrophe-exposed property and specialty risks. Gross premiums written through these programs that were ceded to the Nephila Reinsurers were $267.4 million and $389.3 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026 and December 31, 2025, reinsurance recoverables on the consolidated balance sheets included $267.6 million and $496.0 million, respectively, due from the Nephila Reinsurers. Under its programs with the Nephila Reinsurers, the Company bears underwriting risk for annual aggregate agreement year losses in excess of a limit the Company believes is unlikely to be exceeded. To the extent losses under these programs exceed the prescribed limits, the Company is obligated to pay such losses to the cedents without recourse to the Nephila Reinsurers. While the Company believes losses under these programs are unlikely, those losses, if incurred, could be material to the Company's consolidated results of operations and financial condition. The Company has also entered into other assumed and ceded reinsurance transactions with the Nephila Reinsurers in the normal course of business, which are not material to the Company's consolidated financial statements. Hagerty The Company holds a minority ownership interest in Hagerty, which operates as a managing general agent focused on the global automobile enthusiast market and also includes Hagerty Re, a Bermuda Class 3 reinsurance company. The Company writes U.S. classic car business on behalf of Hagerty. Effective January 1, 2026, the Company's business with Hagerty transitioned to a fronting arrangement, whereby the Company receives a fronting fee in exchange for writing business on behalf of Hagerty and ceding it to Hagerty Re. Prior to transitioning to a fronting arrangement, the majority of the Company's business with Hagerty was ceded to Hagerty Re. Gross written premiums attributable to Hagerty for the three months ended March 31, 2026 were $253.3 million, all of which were ceded, including $242.1 million ceded to Hagerty Re. For the three months ended March 31, 2025, gross written premiums attributable to Hagerty were $219.9 million, of which $169.7 million were ceded to Hagerty Re. In connection with the transition, the Company also entered into agreements with Hagerty Re to reinsure its retained exposures on business written on behalf of Hagerty prior to January 1, 2026. Net losses and loss adjustment expenses and unearned premiums on these ceded policies totaled $62.2 million and $92.5 million, respectively, as of December 31, 2025. See note 6 for additional details on the Company's retroactive reinsurance agreement with Hagerty. As of March 31, 2026 and December 31, 2025, reinsurance recoverables on the consolidated balance sheets included $298.0 million and $317.1 million, respectively, due from Hagerty Re.
