WASHINGTON, D.C. — On February 27, Defense Secretary Pete Hegseth designated artificial intelligence company Anthropic as a 'supply chain risk,' a classification previously applied to foreign firms like Huawei. Anthropic filed a lawsuit in the Northern District of California challenging the designation, and in late March, Judge Rita Lin issued a court order blocking the Pentagon’s action.

The dispute stems from Anthropic’s $200 million contract with the Pentagon, which the company conditioned on restrictions against using its Claude AI system for fully autonomous weapons or mass domestic surveillance. Anthropic refused to grant the Defense Department unrestricted authority over those use cases, citing existing U.S. legal prohibitions on such applications.

Anthropic has cut off Chinese firms linked to the Chinese Communist Party and shut down state-sponsored Chinese operations attempting to misuse its technology, a move that cost the company several hundred million dollars in potential revenue.

The legal conflict drew attention from other AI firms. In late February, OpenAI announced its own classified-deployment agreement with the Pentagon. Sam Altman, CEO of OpenAI, wrote in a memo to staff that the Anthropic-Pentagon dispute had become 'an issue for the whole industry,' and committed OpenAI to red lines prohibiting mass domestic surveillance, fully autonomous lethal weapons, and requiring human oversight for high-stakes automated decisions.

OpenAI initially faced criticism over its Pentagon deal. Civil society organizations and departing employees criticized the original agreement as insufficiently protective. Within days, OpenAI revised the contract after the resignation of robotics lead Caitlin Kalinowski and an open letter signed by hundreds of OpenAI and Google employees in support of Anthropic. Altman later described the original OpenAI-Pentagon deal as 'sloppy and opportunistic.'
