Anthropic Supply Chain Risk Designation Stands
The Anthropic supply chain risk case has produced a setback for the AI company. A federal appeals court in Washington, D.C., ruled 2-1 to uphold the Pentagon's designation from March, rejecting Anthropic's main arguments that the action was arbitrary, unauthorized, and unconstitutional. The majority found sufficient support for viewing Claude's continued integration into Defense Department and contractor information systems as a national-security risk.
How the Designation Affects Claude
The designation bars the U.S. military from using Anthropic's models and prevents defense contractors from using them in work for the agency. The dispute followed failed negotiations over deploying Claude on the Defense Department's GenAI.mil platform. The Pentagon sought unrestricted military access for all lawful purposes, while Anthropic wanted assurances against uses including fully autonomous weapons and domestic mass surveillance.
Further Review Remains Open
The ruling will not take immediate effect, giving Anthropic time to seek rehearing by the same panel or an en banc review by the full D.C. Circuit. The company could also ask the Supreme Court to hear the case. Separately, a federal judge in San Francisco has already found the government's parallel designation unlawful, so the broader legal dispute remains unresolved.
The conflict illustrates how military demands for availability and ultimate control can collide with a model developer's safety boundaries. The appeals court deferred the risk balance to the president and defense secretary, but further review and the legal distinction between the two designations remain important. They may determine whether Anthropic can restore relevant government business and shape how safety restrictions are negotiated in future public-sector AI contracts.
