Accelerant Holdings (ARX) is a specialty insurance marketplace company that operates a Risk Exchange connecting entrepreneurial managing general agents (MGAs) with reinsurance capital partners. Revenue comes from direct commission income earned by the Exchange Services and MGA Operations segments, plus net earned premiums and ceding commission income generated through its Underwriting segment, which houses Accelerant's own insurance carriers. For the year ended December 31, 2025, total revenues reached $912.9 million across three reportable segments: Exchange Services ($334.9 million), MGA Operations ($249.1 million), and Underwriting ($430.9 million). Accelerant was founded in 2018, launched European operations that year, entered the United States by end of 2020, and launched Mission Underwriters, an MGA incubator providing start-up financing and turnkey operational support to entrepreneurial underwriters, in 2021. Members operate under five-year rolling exclusivity agreements on the Risk Exchange. General and administrative expenses were $249.3 million for the year ended December 31, 2024, up 36.6% year over year, driven primarily by headcount growth.
