Pentagon blacklists Anthropic, labels AI company "supply chain risk"

Dave Lawler, Maria Curi

President Trump said Friday the U.S. government would blacklist Anthropic, and the Pentagon declared the company a "supply chain risk," in the most consequential and controversial policy decision to date at the intersection of artificial intelligence and national security. The big picture: Anthropic rebuffed the Pentagon's demand to lift all safeguards on the military's use of its model, Claude, due to its concerns about the use of AI for mass domestic surveillance and the development of weapons that fire without human involvement.

For that, the government will now impose a penalty usually reserved for companies from adversarial countries, such as Chinese tech giant Huawei. By Friday evening, Anthropic said it would challenge any "supply chain risk" designation in court, and rejected Hegseth's claim that military contractors would be barred from working with the company.
