A federal court rules the Pentagon illegally blacklisted Anthropic

A federal judge just ruled that the Pentagon broke the law when it blacklisted Anthropic over its AI safety guardrails.

According to a report from The Verge, District Judge Rita F. Lin ruled Thursday that designating Anthropic as a "supply chain risk" was unconstitutional. The dispute began when Defense Secretary Pete Hegseth pushed to expand military AI contracts to "any lawful use." Anthropic refused, standing firm against using its tech for mass surveillance of Americans or lethal autonomous weapons. After CEO Dario Amodei maintained that stance, the Department of Defense labeled the startup a national security threat and moved to replace it with seven other AI vendors. Judge Lin called the military's broad measures "unlawful retaliation in violation of the First Amendment."

Why it matters: The decision draws a hard boundary for how the military deals with tech vendors. It clarifies that the government cannot use national security classifications to punish companies that publicly push back on contract terms.

Know this: Anthropic spokesperson Danielle Ghiglieri welcomed the ruling, noting the company remains focused on working with the government to harness AI for national security.

Saying no to the Pentagon is risky, but the court just proved it isn't illegal.
