Overview
- Defense officials said the designation takes immediate effect and requires DoD entities and related contractors to stop using Anthropic’s Claude or certify nonuse for defense work.
- President Donald Trump ordered federal agencies to cease using Anthropic technology at once, granting the Pentagon a six‑month transition to unwind deployments.
- Anthropic said it refused uses for mass domestic surveillance and fully autonomous lethal weapons and announced it will challenge the designation in court.
- Pentagon technology chief Emil Michael linked the dispute to future programs such as the Golden Dome missile defense concept and argued exceptions are impractical, noting rivals accepted broader terms for “all lawful uses.”
- Claude had been integrated into classified workflows and used in recent operations, agencies like Treasury moved to terminate partnerships, Microsoft said most customers can still access Anthropic products outside defense, and consumer adoption of Claude spiked to top app‑store rankings.
