Judge Lin Grants Anthropic Preliminary Injunction Against Department Of War

Judge Lin granted Anthropic a preliminary injunction late last night, imposing a seven-day stay while litigation proceeds and issuing a forceful written opinion criticizing the government's case. Anthropic filed responsive briefs and sworn testimony (including Sarah Heck and Thiyagu Ramasamy) asserting negotiations continued until March 4, 2026, and that the Department of War's supply-chain risk designation reflected factual misunderstandings. The ruling preserves Anthropic's operations pending further proceedings.
