On February 27, 2026, President Trump posted on Truth Social directing all federal agencies to “immediately cease” use of Anthropic’s artificial intelligence (“AI”) technology. Simultaneously, Defense Secretary Pete Hegseth announced on X he was designating the company a “supply chain risk to national security” and prohibiting federal contractors from doing any business with Anthropic. This unprecedented action against a domestic company has significant supply chain implications for government contractors. Below, we summarize what led to this development, the legal authorities pertaining to supply chain bans, and practical guidance for contractors navigating this evolving situation.

1.&nbsp;Background: From Contract Dispute to Presidential Directive

The conflict between Anthropic and the federal government emerged from a contract dispute over the company’s AI usage restrictions. Anthropic, which holds a $200 million Pentagon contract and was the first frontier AI company to deploy its models on classified government networks, maintained two “red lines” in its contract negotiations: it refused to allow its AI model, Claude, to be used for mass domestic surveillance of Americans or in fully autonomous weapons systems.

The Pentagon demanded that Anthropic agree to “all lawful use” of its technology without Anthropic’s proposed restrictions. Anthropic’s refusal led President Trump and Secretary Hegseth to announce their decisions against Anthropic on social media. Secretary Hegseth stated that Anthropic would be “immediately” designated a supply chain risk, prohibiting any federal contractor working with the military from “any commercial activity with Anthropic.”

Anthropic has announced it will challenge the supply chain risk designation in court, calling it “legally unsound.”
