What just happened? A federal judge has ordered the Trump administration to rescind its designation of Anthropic as a supply-chain risk, ruling that the government violated the AI company's First Amendment rights. The decision found the designation was not supported by evidence of a genuine national-security threat and instead stemmed from Anthropic's objections to Pentagon plans for using its AI models.
US District Judge Rita F. Lin ruled late Thursday that the government failed to show Anthropic posed a national-security threat. Instead, she found that officials acted against the company after it publicly challenged the Pentagon's plans for using AI.
"Defendants' contemporaneous words and deeds confirm that the challenged actions were based on a desire to make a public example out of Anthropic for its 'arrogance' in criticizing the government," Lin wrote.
The ruling requires the government to withdraw guidance, directives, and other communications that blacklisted Anthropic or labeled it a supply-chain risk.
Anthropic sued the administration in March after talks with the Pentagon over military use of its AI models broke down. The company had asked for limits on the use of its technology in fully autonomous weapons and domestic surveillance. The Pentagon wanted an agreement allowing the military to use Anthropic's models for any legal purpose.
The dispute centered on whether Anthropic could place limits on how the government used its models after making them available to federal agencies. The Pentagon viewed Anthropic's proposed restrictions as too narrow for military operations. Anthropic said the limits were needed for high-risk uses of AI.
Government lawyers argued that the Pentagon was allowed to choose vendors it considered reliable. They said Anthropic could make undisclosed changes to its models that might affect military operations.
"The Department of War needs to trust that its AI vendors are going to be forthright and honest with the department," government attorney James Harlow said during court arguments.
Lin questioned that position during the case. At a July hearing, she called the government's argument that it could retaliate against a contractor for criticizing the administration "really troubling" and "quite extreme."
The designation had immediate business consequences for Anthropic. The company said the government action led to hundreds of millions of dollars in canceled, shortened, or delayed contracts. Documents filed in the case showed rivals, including OpenAI, were preparing to replace Anthropic in parts of the federal government.
The decision also comes as Anthropic's technology remains in use across the US government. Claude has been used by the military, including in the January raid in Venezuela and the war with Iran. Other federal agencies continue to use Anthropic products, including Fable and Mythos.
Lin said that continued government use undercut the Pentagon's claim that Anthropic was a national-security risk. She had previously issued a preliminary injunction in March that blocked parts of the designation while the case moved forward.
Anthropic and the administration reached a separate agreement in June that allowed the company to release Fable and Mythos following a shutdown tied to security concerns. That agreement did not resolve the lawsuit over the blacklist.
The Defense Department did not immediately respond to a request for comment. The administration could appeal Lin's decision. A separate case involving Anthropic remains before a federal appeals court in Washington, which denied the company's request in April to block other parts of the designation.
