Trump Bans Anthropic AI in Government After Pentagon Dispute

President Donald Trump has ordered all U.S. Federal agencies to cease using technology from artificial intelligence company Anthropic, escalating a dispute over the military’s desired use of the AI model and raising concerns about the future of a $200 million Pentagon contract. The move, announced on February 27, 2026, comes after Anthropic refused to grant the Defense Department unrestricted access to its AI technology.

Pentagon Demands and Anthropic’s Concerns

The Pentagon sought assurances that its AI models would not be used for fully autonomous weapons or mass domestic surveillance of Americans. Anthropic, however, insisted on safeguards to prevent such applications. Defense Secretary Pete Hegseth issued a deadline of 5:01 p.m. ET on Friday, February 27, for Anthropic to agree to the Pentagon’s demands, which was not met according to CNBC.

Trump’s Response and Agency Phase-Out

In a post on Truth Social, President Trump directed all federal agencies to “immediately cease” using Anthropic’s technology. He announced a six-month phase-out period for agencies currently utilizing Anthropic’s products, such as the Department of Defense. Trump also threatened further action against the company if it doesn’t cooperate during the transition as reported by CBS News.

Designation as a National Security Risk

Following Trump’s order, Defense Secretary Hegseth announced the Pentagon would designate Anthropic as a “Supply-Chain Risk to National Security.” This designation effectively bars any contractor, supplier, or partner doing business with the U.S. Military from engaging in commercial activity with Anthropic according to CNBC. Anthropic will be allowed to continue providing services to the Department of Defense for up to six months to facilitate a smooth transition.

Anthropic’s Stance

Anthropic maintained its position, stating that its stance is “fundamentally incompatible with American principles” as stated by Hegseth. The company’s CEO, Dario Amodei, previously expressed concerns about the potential misuse of its AI technology.

Contract at Risk

The dispute puts a $200 million contract signed between Anthropic and the Pentagon in July at risk. The future of this contract, and Anthropic’s relationship with the U.S. Government, remains uncertain.
