Appeals court upholds Pentagon’s supply-chain risk label for Anthropic

WIRED reports that a divided federal appeals court panel in Washington, DC, rejected Anthropic’s challenge to one Pentagon supply-chain risk designation on September 25, 2026. Anthropic had argued that its rights were violated. The majority said the Pentagon had “ample support” for concluding that continued integration of Claude into its systems presented a national-security risk covered by law. WIRED says the Pentagon’s sanctions aimed to remove Claude from the military and other parts of the federal government by September 2026, but the department had not provided detailed updates on replacing it.
