100-word summary
The Defense Department branded Anthropic a "supply chain risk" on March 5, the first time it's used that designation against a U.S. company. Anthropic sued four days later, arguing the Pentagon violated its constitutional rights after the AI lab refused to drop limits on mass surveillance and autonomous weapons use. Claude had been embedded in military systems like Maven for intelligence analysis and targeting. The fight reveals a stark divide: Anthropic wants guardrails on how its models get used in warfare; the Pentagon wants unrestricted access across all programs. The outcome could set the template for every AI lab negotiating government contracts going forward.
