Accelerant
Data-driven specialty insurance risk exchange connecting MGAs and underwriters with global risk capital partners, publicly traded on NYSE under ticker ARX.
Overview
Accelerant is a technology-driven specialty insurance risk exchange founded in December 2018 by Jeff Radke and Chris Lee-Smith. The company was conceived to address the structural disadvantages faced by smaller specialty underwriters -- specifically the opacity, friction, and misaligned incentives embedded in the traditional specialty insurance value chain. Radke previously served as CEO of PXRE Group and held senior roles at Argo Group.
The company operates a data-driven Risk Exchange that connects specialty MGAs and underwriters (its "Members") with a diversified pool of risk capital partners (carriers, reinsurers, and institutional investors). Its proprietary platform ingests and validates data from members in real time, providing advanced analytics, AI-driven risk scoring, automated underwriting referrals, and portfolio monitoring -- enabling capital to flow efficiently to the best-performing underwriters. As of Q4 2025, Accelerant had 265 members and more than 95 risk capital partners spanning 22 countries and 500-plus specialty insurance products.
Accelerant reached unicorn status in 2022 at a USD 2.1 billion valuation and completed its IPO on the New York Stock Exchange in July 2025 (ticker: ARX), raising approximately USD 724 million. For full-year 2025, the company reported Exchange Written Premium of USD 4.19 billion (up 35% YoY) and revenue of USD 913 million (up 51% YoY), with adjusted EBITDA of USD 282 million (up 149% YoY). The USD 1.35 billion net loss for 2025 reflects a non-cash IPO-related profits interest distribution.
