Released court documents from July 2, 2026, provide insight into the collapse of the partnership between Anthropic and the US Department of Defense. Tensions centered on Anthropic CEO Dario Amodei's refusal to permit his company's AI models to be integrated into autonomous weapons systems or domestic surveillance tools. The Department of Defense maintained a stance of utilizing the technology for all lawful uses, a policy Emil Michael, the undersecretary of defense for research and engineering, argued provided necessary flexibility.

The correspondence indicates that the friction escalated in January after weeks of limited communication. Emil Michael, a former Uber executive, contacted Dario Amodei seeking alignment on the Pentagon's terms. When Dario Amodei insisted on clear guardrails against specific applications, Emil Michael rejected these restrictions as unworkable. Emil Michael explicitly stated that the agency makes no distinction between defensive and offensive weapons, rendering Dario Amodei's attempt to categorize usage types futile under the Pentagon's legal framework.

Throughout the negotiation, Dario Amodei expressed concern that proposed language from the Department of Defense would remove established safety redlines. Following these disagreements, Defense Secretary Pete Hegseth officially designated Anthropic as a supply-chain risk, effectively terminating the professional relationship. Reports note that Emil Michael held significant stock in xAI, a competitor to Anthropic, adding a layer of potential conflict regarding his advocacy for the department's access to the models. The full account is contained within a 346-page document released by the court.
