A federal judge has ruled in favor of artificial intelligence company Anthropic in its legal battle against the Pentagon after the government labeled the company as a supply chain risk earlier this year.

U.S. District Judge Rita Lin issued a written order Thursday night that the Pentagon acted illegally by punishing the AI company for its criticism of the Department of Defense's views on AI use. The government is expected to fight the ruling.

The dispute between the AI company and the government broke out in February when President Donald Trump and Defense Secretary Pete Hegseth accused Anthropic of endangering national security and designated the company a supply chain risk. Anthropic CEO Dario Amodei refused to back down over concerns the company's products could be used for mass surveillance or autonomous armed drones.

Lin wrote that the government's actions "were based on a desire to make a public example out of Anthropic for its 'arrogance' in criticizing the government, not based on any articulable basis to believe that Anthropic would actually sabotage its model."

An Anthropic spokesperson said in a statement that they welcome the judge's ruling: "We remain focused on working productively with the government to harness AI for our national security so all Americans benefit from this technology."

The White House did not immediately respond to a request for comment.

In the 59-page ruling, Lin, an appointee of former President Joe Biden, wrote that neither the Constitution nor the federal statute the government invoked allows them to "impose sweeping penalties based principally on Anthropic's critique of the Administration's views."
