Anthropic on Wednesday sought a stay from a U.S. appeals court after the Pentagon said the company was a supply-chain risk, pending a judicial review of the case, adding that the designation could cost it billions of dollars in lost revenue.

Anthropic’s latest request comes after a weeks-long dispute over technology guardrails on the use of Anthropic’s artificial intelligence tools by the U.S. military. Defense Secretary Pete Hegseth labelled the firm a supply-chain risk and barred the Pentagon and its contractors from using its AI products.

The AI firm separately filed a lawsuit earlier this week in a California federal court to challenge its Pentagon blacklisting.

In a filing with the U.S. Court of Appeals for the District of Columbia Circuit on Wednesday, Anthropic said the Pentagon’s supply-chain designation would cause the company “irreparable harm.”
