A federal judge ruled the Defense Department's March ban on Anthropic's Claude AI model for military use was unlawful, overturning the blacklist.
Published
A U.S. federal judge has blocked the Pentagon's blacklist of Anthropic, ruling that the Trump administration's decision to bar the military from using Claude was illegal. The Defense Department had banned the use of Anthropic's Claude AI model by the U.S. military in March. The ruling marks a significant reversal of the government's attempt to restrict the AI company's products from defense contracts. The judge's decision prevents the blacklist from taking effect and opens the door for Anthropic to pursue government and military contracts. This case represents one of the first major legal tests of the administration's AI procurement restrictions. Anthropic declined to comment on pending litigation, while the Pentagon has not yet responded to the ruling. Legal experts say the decision could influence similar challenges to government technology blacklisting efforts.
