AIG Launches Lloyd’s Syndicate 2479 with Amwins and Blackstone, Partners with Palantir for GenAI‑Powered Underwriting

AIG
December 19, 2025

AIG has created Lloyd’s Syndicate 2479, a special‑purpose vehicle that will begin underwriting $300 million of premium on January 1, 2026. The syndicate is jointly backed by specialty insurer Amwins and alternative‑asset manager Blackstone, and will be managed by Talbot Underwriting Limited. The partnership gives AIG access to Amwins’ $6 billion of delegated authority premiums and Blackstone’s capital to support a diversified underwriting portfolio.

The syndicate launch is part of AIG’s broader “digital twin” strategy, which seeks to embed generative AI across core operations. By combining Amwins’ distribution network, Blackstone’s capital, and Palantir’s Foundry platform, AIG aims to accelerate underwriting decisions, improve risk selection, and unlock new growth opportunities in the Lloyd’s market. The GenAI collaboration will use large‑language‑model agents to retrieve and analyze data from an ontology that covers more than four million industry data points, enabling real‑time risk assessment and portfolio optimization.

AIG’s Q3 2025 earnings provide context for the initiative. Adjusted earnings per share rose to $2.20, a 77% year‑over‑year increase, while revenue climbed to $7.1 billion, up 3.2% from the prior year. The gains were driven by strong performance in the North America Commercial and International Commercial segments, where premium growth and underwriting income supported the company’s profitability. The new syndicate and AI partnership build on this momentum, positioning AIG to sustain its earnings trajectory while expanding its specialty underwriting footprint.

The GenAI partnership leverages Palantir’s Foundry platform and large‑language‑model agents to rapidly retrieve data and evaluate risk characteristics across the syndicate’s portfolio. The collaboration also involves AIG developing an ontology that allows the AI to access over four million industry data points, enhancing underwriting analytics. This technology is expected to reduce processing time, improve data accuracy, and enable more precise pricing and risk selection, thereby increasing underwriting efficiency and margin potential.

Peter Zaffino, AIG’s Chairman and CEO, emphasized that the partnership represents a “next level of innovation” and that speed drives growth. Scott Purviance, CEO of Amwins, highlighted the opportunity to deploy aligned capital alongside a dedicated underwriting portfolio. Alex Karp, Palantir’s CEO, noted that the collaboration “will transform the insurance industry” by combining data‑driven insights with AIG’s underwriting expertise.
