06:18 AM EDT, 03/12/2026 (MT Newswires) -- Amazon ( AMZN )-backed (AMZN) Anthropic is petitioning an appeals court to block the Pentagon from designating it a supply-chain risk pending a ruling, news outlets reported Wednesday, citing court filings.

The company said the designation, which it is challenging in court, could potentially cost it billions in revenue, Reuters reported.

Anthropic and the Pentagon are in a dispute over the military's alleged use of AI technology for mass surveillance and autonomous warfare, news outlets reported.

Anthropic and the Pentagon did not immediately reply to MT Newswires' request for comment.
