LSEG MaaS (Model-as-a-Service) is a governed marketplace launched by LSEG in February 2026, enabling banks, buy-side firms, and analytics vendors to host, distribute, and run financial models. The platform targets secure model sharing and monetization, with Societe Generale as the first major partner publishing seven datasets and analytics.
