Anthropic Secures Court Injunction Blocking Pentagon’s Supply-Chain Risk Designation
Generative AI firm Anthropic has won a preliminary injunction that bars the U.S. Department of Defense from classifying the company as a national supply-chain risk, a decision that could clear a path for clients to resume commercial work with the AI developer.
Thursday’s ruling, issued by U.S. Federal District Judge Rita Lin of San Francisco, marks a symbolic defeat for the Pentagon and a significant boost to Anthropic as the company fights to protect its business operations and public reputation.
“Defendants’ designation of Anthropic as a ‘supply chain risk’ is likely both contrary to law and arbitrary and capricious,” Lin wrote in her justification for the temporary court order. “The Department of War provides no legitimate basis to infer from Anthropic’s forthright insistence on usage restrictions that it might become a saboteur.”
Neither Anthropic nor the Pentagon immediately responded to requests for comment on the ruling.
Over the past two years, the Department of Defense — which the Trump administration refers to as the Department of War — has leveraged Anthropic’s Claude AI tools to draft sensitive documents and analyze classified data. But earlier this month, the Pentagon began cutting ties with Claude after concluding Anthropic could not be trusted as a vendor. Defense officials cited multiple instances where Anthropic allegedly imposed, or attempted to impose, usage limits on its technology that the Trump administration considered unnecessary.
The Trump administration ultimately issued a series of directives, including the controversial supply-chain risk designation, that gradually halted all use of Claude across the federal government, harming Anthropic’s sales trajectory and public standing. The company filed two separate lawsuits challenging the sanctions as unconstitutional. During a Tuesday hearing ahead of the ruling, Lin noted the government had appeared to illegally “cripple” and “punish” Anthropic through its actions.
Lin’s Thursday ruling “restores the status quo” to conditions on February 27, the date before the administration’s directives went into effect. “It does not bar any defendant from taking any lawful action that would have been available to it” on that date, she wrote. “For example, this order does not require the Department of War to use Anthropic’s products or services and does not prevent the Department of War from transitioning to other artificial intelligence providers, so long as those actions are consistent with applicable regulations, statutes, and constitutional provisions.”
The ruling clarifies that the Pentagon and other federal agencies still remain free to cancel existing contracts with Anthropic and order third-party contractors that integrate Claude into their own tools to stop using the software — they just cannot use the invalidated supply-chain risk designation as the legal basis for those steps.
The immediate real-world impact of the ruling remains unclear, as Lin’s order will not go into effect for one week. A federal appeals court in Washington, D.C., also has not yet ruled on Anthropic’s second lawsuit, which focuses on a separate law that was also used to bar the company from supplying software to the U.S. military.
Even so, Anthropic can use Judge Lin’s ruling to reassure clients wary of partnering with a firm labeled a supply-chain risk, demonstrating that courts may ultimately side with the company long-term. Lin has not yet scheduled a timeline for a final ruling in the case.
