Judge strikes down Pentagon's blacklist of Anthropic
A federal judge has thrown out the Pentagon's designation of Anthropic as a supply-chain risk, handing the Claude maker a decisive win in one of the most closely watched legal fights between an AI lab and the US government.
A California federal judge ruled Thursday that the Pentagon's blacklisting of Anthropic was unconstitutional, vacating the supply-chain risk label that Defense Secretary Pete Hegseth had placed on the company. US District Judge Rita Lin found that officials retaliated against Anthropic in violation of the First Amendment and stripped the company of its liberty interests without adequate notice or a meaningful chance to respond. "Neither the Constitution nor the federal statute invoked by Defendants allows them to impose sweeping penalties based principally on Anthropic's critique of the Administration's views," Lin wrote, adding in the ruling's sharpest line that "the empty invocation of national security is not a blank check to punish and retaliate against government critics."
The dispute traces back to a $200 million contract fight over how the Pentagon could deploy Anthropic's Claude models on classified systems. Anthropic demanded contractual limits barring its models from use in autonomous lethal weapons or domestic mass surveillance — conditions the Defense Department rejected, arguing corporate contractors have no authority to dictate military operating rules. When negotiations collapsed, Hegseth hit Anthropic with a designation historically reserved for foreign threats, effectively cutting the company off from every Pentagon contractor and supplier. Anthropic sued in March, and Thursday's order sets the designation aside with a permanent injunction.
Why it matters: this is the first time a court has drawn a hard legal line around the AI-safety principles that labs are trying to write into government contracts. The judge didn't order the Pentagon to buy Anthropic's products, and the military remains free to pick other AI vendors. But the ruling signals that a lab's refusal to let its models be used for lethal autonomy can't be punished as a national-security risk. For an industry watching Anthropic, OpenAI, and Google all jockey for defense deals, that's a precedent with real teeth — and a rebuke to the view that criticizing the administration's AI agenda is disqualifying.
