US court to Pentagon: You are 'wrong' in banning Anthropic and labelling it supply chain risk

A San Francisco federal judge has ruled that the Pentagon's decision to blacklist Anthropic earlier this year was unlawful. According to a report by CNBC, the US District Judge Rita Lin found that the Department of Defense violated the First Amendment by designating the AI giant a supply chain risk “based on a desire to make a public example” rather than on any “articulable basis.” The dispute stemmed from collapsed negotiations between Anthropic and the Pentagon over how the military could use the company’s Claude AI models. Anthropic sought assurances its technology would not be deployed for fully autonomous weapons or domestic mass surveillance, while the Pentagon demanded unfettered access for all lawful purposes. When talks broke down, Anthropic became the first U.S. company publicly labeled a supply chain risk, barring defense contractors from using its technology.How the dispute between Anthropic and Pentagon startedThe Defense Department designated Anthropic a supply chain risk in March, a label asserting that the company posed a threat to US national security. The designation followed negotiations over how the military could use Anthropic's Claude AI models that ultimately broke down. Anthropic had sought assurances that its technology would not be used to power fully autonomous weapons or domestic mass surveillance, while the Pentagon wanted the company to grant it unrestricted access to Claude for all lawful government purposes.When those talks collapsed, Anthropic became the first American company to be publicly designated a supply chain risk by the US government — a label that barred defense contractors from using its technology in any work performed for the agency.Anthropic's legal fight with Trump administrationAnthropic responded by suing the Trump administration in both San Francisco and Washington, D.C., seeking to reverse the blacklisting. The dual lawsuits were necessary because the Pentagon relied on two separate designations to justify the supply chain risk action, requiring the company to litigate the matter in two different courts simultaneously.Thursday's ruling resolved only the San Francisco case in Anthropic's favor. The company's parallel litigation in Washington, D.C. remains unresolved, meaning Anthropic technically continues to carry the supply chain risk designation until that second case is decided.What Anthropic has to sayAnthropic welcomed the ruling in a statement to CNBC, with a spokesperson saying the company was pleased the court found the designation unlawful and that it remains focused on working productively with the government to put AI to use for national security in ways that benefit all Americans.IPO implications for AnthropicThe decision clears a major hurdle for Anthropic as it moves toward a near‑record IPO. Reestablishing ties with the Pentagon could open new business opportunities that were cut off by the blacklisting.Get the latest technology news and updates. Download the TOI App.
