The judges ruled that the Pentagon had "ample support" for its decision to designate the company that way pcmag.com.

Coverage described the outcome as judges upholding Anthropic's Pentagon blacklist pcmag.com. A federal appeals court upheld the supply chain risk designation, allowing the Pentagon to exclude Anthropic from defence work news.bitcoin.com.

How the dispute began

The conflict began in February, when Defense Secretary Pete Hegseth demanded that Anthropic change its terms techxplore.com. Anthropic's military contracts were then cancelled and other Pentagon users were barred from its models techxplore.com. The Pentagon designated Anthropic a supply chain risk in early March, after Hegseth's demand yahoo.com.

The Department of Defense sanctioned Anthropic under two separate supply-chain risk laws, aiming to strip Claude out of military systems en.cryptonomist.ch. Hegseth accused Anthropic of endangering national security rutlandherald.com. The ruling was the latest twist in Anthropic's dispute with the Pentagon ctvnews.ca. The department's stated objection was to the company's guardrails on military use techxplore.com.

What to watch

Emil Michael celebrated the decision on X, saying that "the weight of justice has shattered Anthropic's arguments" voz.us. Accounts differ on his title: one identifies him as Deputy Secretary of Defense voz.us, another as Under Secretary of Defense en.ammonnews.net.

The ruling lands ahead of an anticipated Anthropic initial public offering news.bitcoin.com. Its reach is the open question. As described, the order lets the Pentagon exclude the company from Defense Department contracts and military systems, with two separate statutory bases behind the designation en.cryptonomist.chaiweekly.co. The case also sits inside a wider pattern of courts being asked to weigh the administration's national security claims yahoo.com. For investors in AI infrastructure and defence software, the precedent is that a single department can foreclose a vendor without a contracting failure, and that an appellate court will not second-guess it where the record is judged adequate pcmag.comnews.bitcoin.com. The two statutory bases matter here, because a designation resting on more than one law is harder to unwind by curing a single defect en.cryptonomist.ch. The bar also extends to defence contractors, not only to the department itself aiweekly.co.
