Overview
- Anthropic filed two cases on March 9—one in the Northern District of California and one in the D.C. Circuit—seeking to undo the designation and block enforcement, including a temporary restraining order to keep defense work running.
- Defense Secretary Pete Hegseth issued the label on Feb. 27 and President Trump ordered a government‑wide halt on Claude, with the Pentagon planning a six‑month phase‑out to avoid disrupting systems reportedly using the model in classified Iran‑related operations.
- The Pentagon argues vendors cannot restrict wartime decisions and wants access for any lawful use, while Anthropic maintains current AI is too unreliable for fully autonomous targeting and rejects mass domestic surveillance.
- Anthropic’s complaints cite First Amendment and due process violations and warn the action is unprecedented for a U.S. firm, with contracts already in doubt and hundreds of millions of dollars at near‑term risk.
- Competitive and industry fallout accelerated as OpenAI announced a Pentagon deal within hours of the breakdown, and more than 30 OpenAI and Google employees filed an amicus brief supporting Anthropic’s bid for emergency relief.
