Judge rules Pentagon’s supply chain risk designation for Anthropic was illegal

A federal judge has ruled in favor of artificial intelligence company Anthropic in its legal battle against the Pentagon

A U.S. judge on Thursday blocked the Pentagon’s blacklisting of Anthropic, ​the latest turn in the Claude maker’s high-stakes fight with the military over AI safety ‌on the battlefield.

It followed Anthropic's refusal to allow the military to use its AI models for things that included surveillance or autonomous weapons.

She barred the federal agencies named in the lawsuit from enforcing President Donald Trump’s order to stop using the tools of Anthropic – creator of the Claude AI models – and overturned defense secretary Pete Hegseth’s designation of the company as a “supply chain risk”, a status previously reserved for foreign firms.
