Federal Judge Halts Trump Administration's 'Supply Chain Risk' Label for AI Firm Anthropic

A federal judge in San Francisco temporarily blocked the Pentagon's designation of Anthropic as a "supply chain risk" on Thursday, ruling that the government's actions appeared designed to punish the company for its public stance on AI safety rather than to protect national security. Judge Rita Lin of the U.S. District Court for the Northern District of California granted a preliminary injunction that also halts a directive from President Donald Trump ordering all federal agencies to cease using Anthropic's technology. The ruling does not constitute a final decision, as the underlying case continues. Judge Lin put her order on hold for one week to allow the Department of Justice time to appeal, and required the government to submit a report by April 6, 2026, on how it plans to comply.

A $200 million contract dispute sparked the standoff The conflict traces back to negotiations over a 200 (million USD) — defense contract at center of Anthropic-Pentagon dispute contract between Anthropic and the Pentagon, during which Anthropic chief executive Dario Amodei insisted that the company's AI model, Claude, could not be used for fully autonomous lethal weapons or for the mass surveillance of American citizens. The Department of Defense countered that no private contractor could dictate the terms under which the military uses technology it purchases, arguing that military commanders, not vendors, must decide what is safe for AI to do in operational settings. After negotiations broke down, Defense Secretary Pete Hegseth labeled Anthropic a "supply chain risk," a designation that effectively blacklists a company from doing business with U.S. government entities and had never previously been applied to an American company. The label is typically reserved for foreign firms with ties to U.S. adversaries, such as China's Huawei. President Trump subsequently ordered all federal agencies to immediately stop using Anthropic's technology, compounding the reputational and commercial damage to the company. Anthropic argued in court that the designation was causing "irreparable harm" as business partners reconsidered contracts and federal agencies removed Claude from their systems.

The "supply chain risk" designation is a national security tool used by the U.S. government to restrict procurement from entities deemed to pose a threat to critical infrastructure or defense systems. Before the Anthropic case, the label had been applied exclusively to foreign companies, most notably Chinese telecommunications firm Huawei, which was placed on a U.S. government blacklist in 2019. The case raises broader questions about whether the Trump administration could use the same designation against other technology companies that publicly disagree with government decisions about how their products are used.

Judge cites Trump and Hegseth's own words as evidence of retaliation In her written ruling, Judge Lin pointed directly to public statements made by President Trump and Defense Secretary Pete Hegseth, in which they described Anthropic as "out of control" and "arrogant" and characterized the company's safety stance as "sanctimonious rhetoric" amounting to an attempt to "strong-arm" the government. The judge wrote that the court record supports "an inference that Anthropic is being punished for criticizing the government's contracting position in the press." She added that the supply chain risk designation is ordinarily reserved for foreign intelligence agencies and terrorists, not American companies, and that the broad measures taken against Anthropic did "not appear to be directed at the government's stated national security interests." Judge Lin wrote pointedly: "If the concern is the integrity of the operational chain of command, the Department of War could just stop using Claude. Instead, these measures appear designed to punish Anthropic." She also rejected what she called the "Orwellian notion" that an American company could be classified as a potential adversary simply for expressing disagreement with government decisions. The Pentagon had argued in court that Anthropic posed an "unacceptable risk" to national security because the company could theoretically disable or alter its technology to suit its own interests rather than the country's priorities in wartime.

Microsoft, ACLU, and retired military leaders back Anthropic in court Anthropic filed two separate lawsuits against the Trump administration — one in the Northern District of California and a narrower parallel case still pending before the U.S. Court of Appeals for the District of Columbia Circuit — alleging violations of its First Amendment free speech rights and Fifth Amendment due process rights, on the grounds that it was denied any opportunity to contest the designation before it was applied. A broad coalition of organizations filed amicus briefs in support of Anthropic, including Microsoft, the American Civil Liberties Union, and retired military leaders, as well as employees of OpenAI and Google. The Justice Department did not immediately comment on Thursday's ruling but had previously indicated it would appeal. Anthropic spokesperson Danielle Cohen welcomed the decision. „We're grateful to the court for moving swiftly, and pleased they agree Anthropic is likely to succeed on the merits. While this case was necessary to protect Anthropic, our customers, and our partners, our focus remains on working productively with the government to ensure all Americans benefit from safe, reliable AI.” — Danielle Cohen via The Verge The outcome carries implications beyond Anthropic, as legal analysts and technology companies watch whether the Trump administration could deploy the same national security designation against other firms that publicly challenge government use of their products.
