The synthetic intelligence startup sought the motion to pause its blacklisting by the Pentagon and forestall additional financial and reputational hurt because the case unfolds. The ruling comes after a decide in San Francisco federal court docket late final month, in a separate however associated case, granted Anthropic a preliminary injunction that bars the Trump administration from imposing a ban on using Claude.
The DOD declared Anthropic a provide chain threat in early March, which means that use of the corporate’s know-how purportedly threatens U.S. nationwide safety. The label requires protection contractors to certify that they do not use Anthropic’s Claude AI fashions of their work with the navy.
“In our view, the equitable stability right here cuts in favor of the federal government,” the appeals court docket mentioned in its resolution. “On one facet is a comparatively contained threat of monetary hurt to a single non-public firm.

Within the ruling on Wednesday, the court docket acknowledged that Anthropic “will probably endure a point of irreparable hurt absent a keep,” however that the corporate’s pursuits “appear primarily monetary in nature.” Whereas the corporate claimed the DOD was standing in the way in which of its proper to free speech, “Anthropic doesn’t present that its speech has been chilled through the pendency of this litigation,” the order mentioned.
The DOD relied on two distinct designations – 10 U.S.C. § 3252 and 41 U.S.C. § 4713 – to justify the provision chain threat motion, and so they should be challenged in two separate courts. The 41 U.S.C. § 4713 designation falls underneath the purview of the appeals court docket in Washington, D.C.

In a submit on X in late February, Protection Secretary Pete Hegseth declared Anthropic a provide chain threat, and the DOD quickly notified the corporate of the official willpower by way of a letter. Anthropic is the primary American firm to be given the designation, which has traditionally been reserved for overseas adversaries.
Shortly earlier than Hegseth’s submit, President Donald Trump wrote a Fact Social submit ordering federal businesses to “instantly stop” all use of Anthropic’s know-how. He mentioned there could be a six-month phase-out interval for businesses just like the DOD.
The Trump administration’s actions stunned many officers in Washington, the place Anthropic’s know-how had turn out to be embedded in quite a few businesses. The corporate was the primary to deploy its fashions throughout the DOD’s labeled networks, and it was championed for its means to combine with present Protection contractors like Palantir.
Anthropic signed a $200 million contract with the Pentagon in July, however as the corporate started negotiating Claude’s deployment on the DOD’s GenAI.mil AI platform in September, talks stalled.
The DOD needed Anthropic to grant the Pentagon unfettered entry to its fashions throughout all lawful functions, whereas Anthropic needed assurance that its know-how wouldn’t be used for totally autonomous weapons or home mass surveillance.
