A US court has lifted the Pentagon's block on Anthropic, ruling that the Defense Department's decision to treat the Claude developer as a national security risk was unlawful and unfounded. The order came on Thursday, local time.
What the ruling says
Judge Rita Lin rejected the government's core defense: that invoking national security was enough to carry the designation. Doing so, she wrote, is no free pass to punish critics of the government or retaliate against them. Her wording here is rendered from German-language reports of the decision.
The refusal behind the ban
Defense Secretary Pete Hegseth had placed Anthropic on a supply-chain risk footing after the company declined to make its models available for surveillance inside the United States or for autonomous weapons. Anthropic's reasoning runs on two tracks. It argues that AI models are not dependable enough to run weapons on their own, and that domestic surveillance cuts into civil liberties.
Money and legal claims
The company filed suit in March, alleging violations of free speech and of its right to due process. Anthropic says losing defense work could cost it billions of dollars. Neither report puts a specific contract value on that estimate.
How the government answered
Justice Department filings argued that the refusal could endanger military systems during active operations. The Pentagon added that private vendors should not be able to constrain military action. In its account, the designation followed Anthropic's rejection of contract terms rather than the company's public stance on AI safety.
Open questions
The available reporting does not say whether the government will appeal, how many contracts are affected, or when the ruling takes practical effect. Those points stay open here rather than being estimated.
