Trump Blocks Anthropic Government Use

Trump Blocks Anthropic Government Use

28 February 2026

What happened

President Donald Trump ordered federal agencies to cease using Anthropic's AI technology following a public dispute over military application. Defense Secretary Pete Hegseth designated Anthropic a supply chain risk, potentially blocking military vendors from future partnerships. Anthropic CEO Dario Amodei stated the company could not agree to unrestricted military use of its AI, citing concerns over mass surveillance and fully autonomous weapons, despite a $200 million Pentagon contract and a $1 civilian agency supply agreement. Most agencies must stop immediately, while the Pentagon has six months to phase out embedded technology.

Why it matters

Federal agencies must now replace Anthropic's AI, impacting procurement teams and platform engineers who relied on its models. The "supply chain risk" designation prevents military vendors from working with Anthropic, limiting its defence sector market access and potentially affecting its critical partnerships. This follows similar negotiations with Google and OpenAI, indicating a broader government push for unrestricted AI use in national security applications. Founders in the AI sector face increased scrutiny over ethical use policies when engaging with government contracts.
