U.S. Appeals Court Upholds Pentagon Ban on Anthropic's Claude in 2-1 Ruling

3 articles · Updated · CNBC · Sep 25

Summary

  • A Washington appeals court backed the Pentagon's blacklist of Anthropic, ruling 2-1 that the Defense Department could bar Claude models from military systems and contractor work.
  • Judges Gregory Katsas and Neomi Rao said the department had ample support for treating Anthropic as a statutorily covered supply-chain risk tied to national security; Judge Karen LeCraft Henderson dissented.
  • The March designation followed failed negotiations over military use of Claude and has been central to Anthropic's months-long legal fight with the Trump administration.
  • Anthropic said it disagreed and is weighing further review, pointing to a separate San Francisco ruling last month that found one parallel Pentagon designation unlawful.
