Munich Re runs aiSure, its AI insurance unit, and says it has insured AI risk since 2018. Its subsidiary HSB has announced AI liability for small businesses, and in August 2026 it agreed to buy At-Bay.
Mosaic, working with Munich Re's aiSure team, offers cover for financial losses when an AI model misses defined performance thresholds. It targets any company commercialising AI and is meant to complement cyber and tech E&O rather than replace them.
