Anthropic PBC plans to spend $50 billion to build custom data centers for artificial intelligence work in several US locations, including Texas and New York, the latest expensive pledge for infrastructure to support the AI boom.

The new sites, which Anthropic is developing with UK-based Fluidstack Ltd., will start coming online throughout 2026, the company said Wednesday in a statement. The project marks the first major data center build-out that the AI firm has taken on directly, rather than through cloud-computing partners such as Amazon.com Inc. and Alphabet Inc.’s Google.
