What Accelerant does

Accelerant Holdings is a public specialty insurance technology company (NYSE: ARX) founded in 2018 by Jeff Radke and Chris Lee-Smith, headquartered in Atlanta with operations across the US, UK, broader Europe, Canada, Australia, and the Cayman Islands. The company operates the Accelerant Risk Exchange, a cloud-native, data-driven platform built on infrastructure including Snowflake that ingests and validates high-fidelity data from 290+ Member managing general agents (MGAs), processes more than 1.2 million records per month, and exposes live dashboards, AI-driven underwriting referrals, claims recovery, and portfolio monitoring. The platform connects two sides of the specialty insurance value chain: entrepreneurial Member MGAs seeking long-term capacity, and Risk Capital Partners (reinsurers, insurers, and institutional investors) seeking diversified, low-volatility specialty risk portfolios.

The product surface extends well beyond the core Risk Exchange to include MISSION (an MGA incubator with US and UK/EU editions), Reserv (a claims TPA with AI-enabled 24/7 monitoring), Flywheel Re and Flywheel II (reinsurance sidecars providing access to institutional capital), Sproutr (an insurance product-development offering), and the Accelerant Marketplace (launched December 2025, aggregating 80+ vetted technology and service partners with Accelerant-negotiated exclusive pricing). Proprietary AI capabilities include Accelerant Risk Indexing (5.3% documented gross loss ratio improvement), LLM-based claims recovery ($150M in savings for one Member), generative AI-driven claims summarization, anomaly/leakage detection, and predictive risk scoring.

The business model is capital-light and fee-based: Accelerant retains only approximately 9% of premiums written through the exchange on its own balance sheet, with the remainder allocated to Risk Capital Partners, while the company collects fees on exchange written premium. Member relationships are anchored by five-year capacity agreements rather than annual market cycles, and pricing is bespoke and not publicly disclosed. FY2025 revenue was $912.9M (+51% YoY) with $282M in adjusted EBITDA (+149% YoY); Q1 2026 revenue was $273.3M (+54% YoY) and management has guided to at least $5.2B in exchange written premium and $285M in adjusted EBITDA for FY2026. The company completed an upsized IPO on the NYSE in July 2025 and is led by co-founder and CEO Jeff Radke alongside co-founders Chris Lee-Smith (Head of Distribution) and Frank O'Neill (Chief Underwriting Officer), with new CFO Linda Huber (formerly CFO of FactSet, MSCI, and Moody's) appointed in March 2026.

Revenue model

1. Fee-based operating revenue (risk exchange): Capital-light, fee-based revenue generated from the Accelerant Risk Exchange, with only ~9% of premiums retained by Accelerant and the rest allocated to risk capital partners. Fee-based operating revenue grew 52% YoY in Q1 2026.
2. Underwriting/insurance premium retention: Accelerant retains a small share (~9%) of exchange written premium on its own balance sheet, primarily through Accelerant-owned insurance entities (e.g., Accelerant National Insurance, Accelerant Specialty, Accelerant Insurance Europe/UK).
3. Multi-year capacity / portfolio-as-a-service fees: Long-term capacity commitments (e.g., five-year £250m Bspoke Underwriting deal with £50m of annual capital) generate recurring capacity and platform fees from MGAs.
4. Risk Capital Partner portfolio access fees: Reinsurers, insurers and institutional investors pay for access to curated, diversified specialty risk portfolios sourced and managed by Accelerant (Portfolio as a Service).
5. Marketplace partner referral economics: Accelerant curates 80+ technology and service partners in the Accelerant Marketplace and negotiates exclusive pricing for Members, generating referral/partner economics.

The core platform is extended by Mission (an MGA incubator program launched in 2021 that helps underwriters launch their own programs and become Members), Reserv (the in-network Claims TPA providing AI-enabled 24/7 claims monitoring and LLM-based leakage detection), Flywheel Re (a reinsurance sidecar launched in 2022, with Flywheel II added in 2024 to expand institutional-investor capacity), Sproutr (an insurance product-development offering introduced in 2024), and the Accelerant Marketplace (a December 2025 digital platform aggregating 80+ vetted technology and services partners with integrated workflows and Accelerant-negotiated pricing). Together these offerings form an end-to-end stack covering program incubation, underwriting risk selection, reinsurance capacity, claims management, product development, and vendor procurement for specialty MGAs.
