Judge blocks Pentagon's Anthropic blacklisting

A US judge on Thursday blocked the Pentagon's blacklisting of Anthropic, the latest turn in the Claude maker's high-stakes fight with the military.

The judge ruled that the government unlawfully retaliated against the AI start-up 'for constitutionally protected expressive activities.' The federal judge in California wrote that the blacklisting was illegal.

The decision is a significant victory for Anthropic.
