Global reinsurer American International Group (AIG), in collaboration with Amwins, a global distributor of specialty insurance products and services, and funds managed by Blackstone, the world’s largest alternative asset manager, has announced a new Lloyd’s syndicate, Syndicate 2479, a novel structure involving a specialty distributor, insurer and Lloyd’s syndicate backed with third-party capital.
On 1 January 2026, Syndicate 2479 commences underwriting $300m of premium that will be managed by AIG. This portfolio is representative of a broad and highly diversified cross section of Amwins’ ~$6bn of delegated authority premiums. As part of the assessment, AIG deployed Palantir’s Foundry capabilities to validate its in-depth analysis of the portfolio.

Longer term, in collaboration with Palantir, AIG will leverage Palantir’s Foundry platform and multiple Large Language Model agents to quickly retrieve data and evaluate defined risk characteristics to understand how the Amwins’ programme portfolio aligns with the Syndicate’s risk appetite. In connection, AIG has developed an ontology that will enable Large Language Models to access over 4m industry data points to further expand its underwriting capabilities.
“Our partnership with Amwins and Blackstone represents the next level of innovation, technical modelling and use of GenAI for portfolio underwriting. To build a balanced portfolio across lines of business for AIG and our capital partners, we collaborated with Palantir to analyse the portfolio with specific characteristics. The formation of Syndicate 2479, which includes capital investment provided by Amwins and Blackstone, further advances our deployment of GenAI through a capability that can evaluate risk with more data and analytics at the individual level to optimise the special purpose vehicle. We believe this capability will unlock future opportunities for expansion and innovation in specialty and other lines of business,” said Peter Zaffino, Chairman & CEO, AIG. M
