A federal judge in California has blocked the Pentagon's attempt to label Anthropic as a supply chain risk, ruling that this action violated the company's constitutional rights. The judge stated that no statute supports branding an American company as a potential adversary for expressing disagreement with the government.

A preliminary injunction has been granted in the case of Anthropic vs. the U.S. Department of War. This ruling allows Anthropic to proceed with its operations while the legal dispute is resolved.

Anthropic will challenge the Pentagon's designation of the company as a supply-chain risk in court. This decision follows U.S. President Donald Trump's directive for federal agencies to cease collaboration with Anthropic.

Anthropic is facing pressure from the US Department of War, which could set significant legal precedents. The demands made by Secretary Hegseth may have serious implications for the future of AI governance.
