Pentagon Labels Anthropic a "Supply-Chain Risk" After Company Refuses Military Surveillance Contract

The relationship between artificial intelligence companies and the U.S. Department of Defense reached a breaking point in early 2026. The Pentagon formally designated Anthropic as a "supply-chain risk" after the AI safety-focused company declined to provide its Claude models for a military surveillance program. The designation, which could affect Anthropic's ability to work with defense contractors more broadly, drew sharp criticism from across the technology sector. Employees at Google and OpenAI organized open letters and internal petitions rallying to Anthropic's defense, arguing that the Pentagon's move set a dangerous precedent by punishing companies for exercising ethical judgment about how their AI technology is deployed. The incident has become a flashpoint in the wider debate around AI ethics, military applications of generative AI, and whether frontier model developers should have the right to decline government contracts on moral grounds.
