What OAK Global does

OAK Global is a London-headquartered specialty insurance and reinsurance platform operating through Lloyd's Syndicates 2843 (OAK Reinsurance) and 1440 (OAK Enterprise), managed by Polo Managing Agency. Founded in 2024 and structured as OAK Servco Limited, the company provides expert underwriting and tailored risk solutions across multiple lines, including primary reinsurance via Syndicate 2843 and property and specialty retrocession via Syndicate 1440. In 2026, OAK Global expanded its franchise with OAK Horizon, a cross-class underwriting unit targeting interconnected climate and technology risks such as catastrophe protection, parametric covers, energy financing, and technology-linked asset protection.

The company's product portfolio is supported by ROOT Intelligence, a Dublin-based technology subsidiary operating from Trinity College Dublin's innovation hub that combines engineering, compliance, data science, and AI expertise to build proprietary risk tools. ROOT Intelligence delivers OCEAN, an AI-powered risk orchestration platform underpinned by Amazon Web Services. OAK Global also distributes capacity through a coverholder network that includes Descartes Underwriting (parametric), Energetic Capital (clean energy credit insurance), and New Energy Risk (US tax credit insurance). The company maintains AM Best, S&P, and Fitch financial strength ratings and secured reinsurance retrocession through a $150 million debut catastrophe bond issuance (Quercian Re 2026-1) via the Arthur Re Ltd. platform managed by Artex Risk Solutions.

OAK Global generates revenue through insurance underwriting premiums and reinsurance solutions across multiple lines of business, supplemented by capital-markets-linked instruments such as catastrophe bonds. The go-to-market is enterprise field sales targeting brokers, coverholders, and cedants, with bespoke solutions delivered through long-term partnerships. Target customer segments include high-net-worth individuals, data centre operators, clean energy and infrastructure projects, and US clean energy tax credit insurance markets. Combined gross written premium across the two syndicates is targeted at $910 million for 2026.
