US Judge Rules Pentagon’s Anthropic Blacklisting Unlawful

A federal judge on Thursday ruled that the Trump administration violated the law when it labeled artificial‑intelligence developer Anthropic as a “supply‑chain risk” earlier this year. The 59‑page opinion by U.S. District Judge Rita Lin found that the government’s designation was an unlawful response to Anthropic’s refusal to comply with demands from the Department of Defense, concluding that “the empty invocation of national security is not a blank check to punish and retaliate against government critics.” Anthropic, which builds large‑language models for commercial use, had argued that the label could cost the company billions of dollars in lost business and cause lasting reputational damage.

The ruling underscores the limits of executive authority in applying national‑security justifications to private‑sector firms that decline government contracts. By striking down the supply‑chain risk designation, the court opened the way for Anthropic to seek redress for the alleged harms and signaled heightened scrutiny of similar actions targeting technology companies. The decision may influence how future administrations assess and label potential security concerns within the rapidly expanding AI industry.
