A US District Judge on Thursday blocked the Pentagon's blacklisting of Anthropic, marking a significant development in the company's high-stakes dispute with the military over AI safety. According to reports from Reuters, US District Judge Rita Lin, an appointee of former Democratic President Joe Biden, made the ruling in a 59-page order where she found that the Pentagon's decision was 'illegal and baseless'. The judge wrote that 'the empty invocation of national security is not a blank check to punish and retaliate against government critics' and that 'the government's actions were based on a desire to make a public example out of Anthropic for its ‘arrogance’ in criticizing the government, not based on any articulable basis to believe that Anthropic would actually sabotage its model'. In the ruling, Lin stated that 'neither the Constitution nor the federal statute the government invoked allows them to “impose sweeping penalties based principally on Anthropic’s critique of the Administration’s views.'
The ruling comes as Anthropic faces potential billions of dollars in lost business and reputational harm from the Pentagon's unprecedented action. According to the latest reports from Reuters, Anthropic executives have warned that the designation could cost the company billions of dollars in lost business and reputational harm. The company welcomed the ruling and stated it remained 'focused on working productively with the government to harness AI for our national security so all Americans benefit from this technology.' In its March 9 lawsuit, Anthropic alleged the government violated its right to free speech under the First Amendment by retaliating against its views on AI safety. The company claims it was not given a chance to dispute the designation, in violation of its Fifth Amendment right to due process. The lawsuit says the decision was unlawful, unsupported by facts and inconsistent with the military's past praise of Claude.
The Pentagon's unprecedented move followed Anthropic's refusal to allow the military to use its Claude AI models for US surveillance or autonomous weapons. As reported by Reuters, Anthropic's lawsuit in California federal court alleges that Defense Secretary Pete Hegseth overstepped his authority when he designated the company a national security supply-chain risk. The designation made by the Pentagon was the first time a US company has been publicly designated a supply-chain risk under an obscure government-procurement statute aimed at protecting military systems from foreign sabotage. The dispute broke out in February when President Donald Trump and Defense Secretary Pete Hegseth accused Anthropic of endangering national security and designated the company a supply chain risk. The designation barred defense contractors from using Anthropic's technology in their work with the agency. The designation came after negotiations about how the military could use Claude AI models spiraled out of control - Anthropic wanted assurance that its technology would not be used for fully autonomous weapons or domestic mass surveillance, while the DOD wanted Anthropic to grant unfettered access to Claude across all lawful purposes.
The Justice Department countered that Anthropic's refusal to lift restrictions could cause uncertainty in the Pentagon over how it could use Claude and risk disabling military systems during operations. As reported by Reuters, Department of Justice lawyers argued in the July hearing that 'the nature of AI models is “so staggeringly enormous and opaque” that the Defense Department cannot evaluate it in the same way it would a physical piece of hardware.' The government stated that the designation stemmed from Anthropic's refusal to accept contractual terms, not its views on AI safety. The legal challenge intensified an unusually public dispute over how AI can be used in warfare and mass surveillance, with Anthropic's primary tech industry rival, ChatGPT maker OpenAI, making its own deal to work with the Pentagon just hours after the government punished Anthropic for its stance. The Pentagon did not immediately respond to a request for comment on the latest ruling.
While Lin's ruling on Thursday handed Anthropic a major victory, the company's litigation in Washington, D.C. is still ongoing. According to CNBC, until that case is resolved, Anthropic still technically remains a supply chain risk. In a statement, Anthropic praised Lin's decision, stating 'We welcome the court's ruling that this supply chain risk designation was unlawful.' The ruling clears a significant hurdle for Anthropic as it marches toward what's expected to be a near-record IPO. While the company has shown no signs of a slowdown since the blacklisting, if it's able to reestablish ties with the Pentagon, it could open additional business opportunities that had been cut off. Anthropic has said it brought the lawsuits an effort to return its business to the status quo before it was designated a supply chain risk, noting that the suits would not require the Pentagon to restart its work with the company.
