On February 26, 2026, the CEO of one of the world’s most powerful AI companies published an open letter refusing a government ultimatum. The Department of War had threatened to designate Anthropic a “supply chain risk”, a label reserved for U.S. adversaries, never before applied to an American company, and to invoke the Defense Production Act to compel the removal of two safeguards: prohibitions on mass domestic surveillance and fully autonomous weapons. Dario Amodei refused. Within 24 hours, the Pentagon followed through, blacklisting Anthropic as a national security risk and ordering all military contractors to immediately cease commercial activity with the company. Anthropic said it would fight the designation in court.
