Judge Tells Pentagon: Blacklisting Anthropic Looks Like an Attempt to "Cripple" the Company
A federal judge delivered a sharp rebuke to the Pentagon at Tuesday's injunction hearing in San Francisco, saying the Department of Defense's "supply-chain risk" blacklisting of Anthropic "looks like an attempt to cripple Anthropic" and that the agency appeared to be "punishing Anthropic for trying to bring public scrutiny to this contract dispute." U.S. District Judge Rita Lin's pointed skepticism is a significant signal heading into a ruling expected within days.
The case centers on Defense Secretary Pete Hegseth's designation of Anthropic as a national security supply-chain risk — a label that blocks the company from certain defense contracts — after Anthropic refused to allow Claude to be used for mass surveillance and lethal autonomous weapons systems without human oversight. Anthropic filed suit alleging the government's actions were unconstitutional and ideologically motivated, backed by sworn declarations from its Head of Policy and Head of Public Sector calling the DoD's core claims flatly false.
The outcome will set binding precedent for whether AI companies can maintain safety guardrails against government customers without facing retaliatory market exclusion. Every frontier AI lab negotiating defense contracts is watching: a ruling for Anthropic would establish that safety conditions are legally defensible; a ruling for the Pentagon could force labs to choose between federal contracts and their own usage policies. The broader stakes — autonomous weapons, civilian surveillance, and the limits of executive power over AI vendors — are unlikely to be resolved in a single hearing.
