Judge blocks Pentagon Anthropic ban

A US judge blocked the Pentagon from blacklisting AI firm Anthropic over battlefield safety restrictions. The court ruled the national security designation was illegal and retaliatory.

A United States federal judge blocked the Pentagon's supply-chain risk designation of Anthropic on Thursday morning, halting a ban that cut the AI developer off from military contracts. The ruling marks a major legal setback for Defense Secretary Pete Hegseth in an escalating dispute over battlefield AI safety. Anthropic filed its lawsuit in California federal court after officials penalized the company for refusing to permit military use of its Claude models in autonomous weapons and domestic surveillance.
