Pentagon Moves to Blacklist Anthropic From Defense Contractors

The Pentagon is laying the groundwork to potentially blacklist Anthropic from the defense supply chain. On Wednesday, the Department of Defense asked Boeing and Lockheed Martin — two of America's biggest defense contractors — to assess how deeply they rely on Anthropic's Claude AI model.

Lockheed Martin confirmed it received the DOD's request. The move signals the Pentagon is serious about evaluating and possibly severing ties between its contractor ecosystem and the AI company.

Asking contractors to audit their AI dependencies is a classic first step before issuing formal restrictions. If the DOD follows through, Anthropic could lose access to one of the most lucrative sectors in tech — defense and national security contracts.

The ask targets two contractors at the heart of U.S. military hardware and systems, making the potential fallout significant.
