Pentagon Wins Appeals Court Ruling on Anthropic Label
Appeals Court Panel Divided Over Pentagon's Anthropic Designation
A three-judge panel on the US Court of Appeals for the DC Circuit ruled Friday that the Pentagon can keep its supply-chain risk label on Anthropic, dealing the AI company a loss in one of two parallel legal fights over the same underlying dispute. The case centers on Claude, Anthropic's flagship AI model, and the company's refusal to let the government deploy it for autonomous weapons systems or domestic surveillance. Defense Secretary Pete Hegseth's department used that refusal as grounds to invoke supply-chain risk statutes earlier this year, ordering Claude stripped from military and other federal systems by this month.
Anthropic has been fighting the designation on two fronts because the two laws behind it required separate court challenges. A federal judge in San Francisco already sided with Anthropic in March, striking down one of the labels, and reaffirmed that ruling last month. Friday's decision in Washington went the other way, leaving the second designation intact.
Anthropic spokesperson Danielle Cohen said the company is weighing its next move, including a possible appeal to a larger DC Circuit panel or to the Supreme Court. The split outcomes leave Anthropic's standing with the Pentagon only partly resolved.
“The department had ample support for its conclusion that the continued integration of Claude into the department’s information systems, by the department or its contractors, presented a statutorily covered national-security risk,” the judges wrote in a majority opinion.
Why this matters
For anyone building on top of Claude, or any model with defense customers, this ruling matters more than the split panel suggests. The court didn't just side with the Pentagon on the facts, it declined to second-guess the department's national-security judgment at all, which sets a low bar for future supply-chain designations against AI vendors. That's a meaningful precedent: if "continued integration" into federal systems can count as a statutory risk without much judicial pushback, other labs with government contracts should expect similar exposure, and similar difficulty getting courts to intervene.
The rejected due process and free speech claims are worth watching too, since they suggest companies challenging these labels can't easily lean on constitutional arguments once an agency cites security concerns. Anthropic hasn't said whether it will appeal further, and the divided panel hints the legal question isn't fully settled. But for now, the message to founders chasing federal deployments is clear: the government's discretion to flag your product as risky, even mid-contract, just got harder to challenge in court.

Common Questions Answered
Why did the Pentagon designate Anthropic as a supply-chain risk?
The Pentagon designated Anthropic as a supply-chain risk because the company refused to allow the government to deploy Claude for autonomous weapons systems or domestic surveillance. Defense Secretary Pete Hegseth's department used this refusal as grounds for the supply-chain risk label, arguing that continued integration of Claude into the department's information systems presented a statutorily covered national-security risk.
What was the DC Circuit Court of Appeals' ruling on Anthropic's supply-chain risk designation?
A three-judge panel on the US Court of Appeals for the DC Circuit ruled that the Pentagon can keep its supply-chain risk label on Anthropic, dealing the AI company a legal loss. The majority opinion stated that the department had ample support for its conclusion that Claude's continued integration into the department's information systems presented a national-security risk.
What precedent does this appeals court ruling set for future AI vendors?
The court's decision sets a low bar for future supply-chain designations against AI vendors by declining to second-guess the Pentagon's national-security judgment. This means that if continued integration of an AI model into federal systems can count as a statutory risk without significant judicial scrutiny, other AI companies with defense customers may face similar designations more easily in the future.
What is Claude and why is it central to this legal dispute?
Claude is Anthropic's flagship AI model that the Pentagon sought to integrate into its information systems. The legal dispute centers on Claude because Anthropic refused to allow the government to deploy it for autonomous weapons systems or domestic surveillance, which prompted the Pentagon's supply-chain risk designation.
