AI startup Anthropic has filed a lawsuit against the US Department of Defense and other federal agencies, seeking a reversal of the blacklisting by the Pentagon, which declared the company a “supply-chain risk.”
In the filing with the US District Court for the Northern District of California, the company states that these actions are “unprecedented and unlawful,” and that they are causing irreparable harm to Anthropic.”
Anthropic’s contracts with the federal government are already being cancelled. Current and future contracts with private parties are also in doubt, jeopardizing hundreds of millions of dollars in the near-term,” the filing said. “On top of those immediate economic harms, Anthropic’s reputation and core First Amendment freedoms are under attack. Absent judicial relief, those harms will only compound in the weeks and months ahead.”
With this declaration, Anthropic becomes the first American company publicly named as a supply chain risk and will require defence vendors and contractors to confirm the discontinuance of the company’s models, known as Claude, in their work with the Pentagon.
The move comes weeks after the department relentlessly chased the AI startup to accept its conditions to loosen certain safeguards governing the military use of its large language models.
Notably, prior to the escalation, it was the first AI company to be approved for classified military networks, among Google, OpenAI, and xAI.
The Dario Amodei-led startup has sought the court to forsake the “supply-chain risk” designation and grant the company a stay on the action as the legal case progresses.
Anthropic’s decision to take the Pentagon to court has gained support from rival companies and employees. Over 30 employees from OpenAI and Google, including Google DeepMind chief scientist Jeff Dean, filed an amicus brief, a legal document filed by individuals or groups who are not parties to a case but have a strong interest in its outcome, demonstrating support for Anthropic in its legal fight against the US government.
Filed hours after Athropic’s suing of the Trump administration, the amicus brief noted, “National security is not served by reckless designations of the military’s American technology partners as a “supply chain risk” or the suppression of public discourse on AI safety. Nor is the United States’ competitiveness in AI development served by the Defendants’ retaliation against one of the leading American companies in our field.”
It also called out the Pentagon for having the option to drop Anthropic’s contract if it no longer wished to be bound by its terms, rather than imposing a “supply-chain risk” designation.
Several other AI leaders have also publicly questioned the Pentagon’s move, including OpenAI’s Sam Altman, who signed its own contract with the Pentagon as its relations soured with Anthropic.
Meanwhile, Anthropic has separately filed for a formal review of the Defense Department’s determination in the US Court of Appeals in Washington, DC.
