Anthropic-Pentagon Dispute Reverberates in European Capitals

The ongoing clash between Anthropic and the United States Department of Defense is playing out less like a procurement dispute between client and supplier and more like a high stakes melodrama, not least because of the Secretary of Defense Pete Hegseth’s decision to designate Anthropic a “supply chain risk” and to take an expansive view of what such a designation entails.

The DoD position—that the designation prohibits companies with defense contracts dealing with Anthropic altogether, rather than just from using its tech on federal government contracts—has elevated the dispute into an existential battle for Anthropic. Unsurprisingly, Anthropic is seeking to overturn the designation in court.

At the core of the dispute are two assurances that Anthropic sought from the Department: that its technology would not be used for “mass domestic surveillance” of US citizens, and that its technology would not be deployed in autonomous weapons. The DoD asserts Anthropic should be content with an assurance its technology would only be used for “any lawful purpose.”
