Anthropic loses appeals court bid to temporarily block Pentagon blacklisting

A federal appeals court in Washington, D.C. denied Anthropic's request to temporarily block the Department of Defense's blacklisting of the company as a supply chain risk (a designation claiming the company's technology threatens U.S. national security). The ruling means Anthropic is excluded from DOD contracts, though a separate court earlier granted Anthropic an injunction allowing it to continue working with other government agencies while the lawsuit challenging the blacklisting continues.
