100-word summary
The Defense Department designated Anthropic a national security risk after disputes over removing Claude's safety guardrails for military use. Anthropic sued immediately, warning the label could cost it billions in 2026 revenue and tank partner relationships. Judge Rita Lin scheduled a March 24 hearing on a preliminary injunction, questioning whether the designation violates the First Amendment. Employees from OpenAI and Google filed amicus briefs backing Anthropic. Defense contractors including Lockheed Martin are already distancing themselves, waiting for the court to rule. The case turns on whether the government can blacklist an AI company over refusing to customize its product for Pentagon missions.
