A federal judge ruled on August 28, 2026, that the Pentagon’s decision to blacklist AI company Anthropic was unconstitutional, handing the company a win in a months-long legal dispute with the Trump administration.
Judge Rita F. Lin, a district judge in the Northern District of California, found that the Defense Department’s designation of Anthropic as a “supply chain risk” amounted to illegal retaliation under the First Amendment. “The empty invocation of national security is not a blank check to punish and retaliate against government critics,” Lin wrote in the ruling, adding that Defense Secretary Pete Hegseth’s decision was “arbitrary and capricious.”
The conflict began when Hegseth moved to renegotiate AI contracts with the military, requiring labs to allow the Pentagon to use their AI for “any lawful use.” Most AI companies agreed to the new terms, but Anthropic refused to drop two restrictions: prohibiting use of its AI for mass surveillance of Americans and for lethal autonomous weapons systems — defined as AI capable of selecting targets without human oversight.
After Anthropic CEO Dario Amodei publicly declared the company would not change its position, the Pentagon designated Anthropic a supply chain risk — a classification typically reserved for national security threats — and signed replacement deals with seven other AI labs, including Google, Microsoft, OpenAI, and SpaceX.
Anthropic filed suit in a California district court in March, and Judge Lin issued a temporary block on the blacklist at that time, noting the Pentagon’s own records showed Anthropic was designated due to its “hostile manner through the press.” Thursday’s ruling formalized that position.
In a statement, Anthropic spokesperson Danielle Ghiglieri said the company “welcomes the court’s ruling” and remains focused on “working productively with the government to harness AI for our national security.”
The ruling may signal limits on how federal agencies can use national security classifications against companies that publicly challenge government contracting terms.
