Appeals Court Upholds Pentagon's Supply-Chain Risk Designation of Anthropic

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit rejected Anthropic's appeal 2:1, upholding the Pentagon's decision to list it as a "supply chain risk." This means Claude remains barred from U.S. military uses and from work by defense contractors related to the Department of Defense, and Anthropic's relationship with the U.S. government will stay constrained under this restriction. Reuters, CNBC, The New York Times and other outlets covered the ruling; Anthropic says it is considering further appeal or review.

Confirmed

• The D.C. Circuit upheld the Pentagon's supply-chain risk designation for Anthropic 2:1, rejecting its appeal (@petrusenkomax, @vitaliychiley citing CNBC; @1411337 citing Reuters)
• The majority opinion held that DoD had sufficient basis to find that Claude integrations pose a national security risk (@nordicinst)
• The court specifically cited Anthropic's own public positions as grounds in the ruling (@nordicinst; the post was truncated, so exact citation details are unclear)
• The ruling means Claude remains banned from U.S. military uses and defense-contractor-related business (@petrusenkomax)
• Anthropic responded that it is weighing further appeal or review (@petrusenkomax)

Why it matters

• The case is a landmark in the relationship between U.S. government agencies and frontier AI companies: the court confirmed DoD's authority to restrict specific AI vendors from the defense supply chain on national security grounds
• Per @nordicinst's analysis, the ruling's reasoning on the legality of risk assessments offers lessons for AI governance and safety frameworks in the EU/Sweden and elsewhere
• Any further appeal or review will determine whether the designation is final, and is worth continued tracking
