A federal judge in California ruled on August 27, 2026, that the Trump administration’s designation of AI company Anthropic as a supply-chain risk by the Department of Defense (DoD) was unlawful. U.S. District Judge Rita Lin found that this label amounted to illegal retaliation in violation of the First Amendment and denied Anthropic due process under the Fifth Amendment. The controversy originated earlier in 2026 when Defense Secretary Pete Hegseth and former President Donald Trump ordered all federal agencies to halt contracts with Anthropic, citing national security concerns related to the company’s AI model use in autonomous weapons and surveillance.

Judge Lin’s ruling criticized the Pentagon’s inconsistent behavior, noting that despite branding Anthropic a security risk, the DoD simultaneously sought contracts with the company and collaborated on the cybersecurity-focused Mythos model. Lin pointed out that the government’s actions seemed aimed at publicly punishing Anthropic for criticizing the administration’s policies, rather than based on genuine security threats. The ruling also confirmed that Anthropic retained full control over its technology with no backdoor access granted to the military once it was handed over.

This court victory marks an important step for Anthropic, which has been actively challenging the supply-chain risk designation through multiple lawsuits, including ongoing litigation in Washington, D.C. The company welcomed the ruling and expressed commitment to productive cooperation with the U.S. government to advance AI applications for national security. Meanwhile, the Pentagon declined to comment on the court’s decision as the second case proceeds.

Anthropic’s legal battle highlights significant tension over the growing role of AI in defense and the limits of government authority to impose restrictive labels on technology providers. The court’s rejection of the supply-chain risk label underscores that claims of national security must have clear justification and cannot be used as a tool to penalize dissenting companies. This case sets a precedent for protecting tech firms’ rights while balancing national security interests in the rapidly evolving AI landscape.
