Anthropic filed a lawsuit against the Trump administration on Monday after the artificial intelligence startup was blacklisted and labeled a threat to U.S. national security.
The company said in a complaint that these actions are “unprecedented and unlawful,” and that they are “harming Anthropic irreparably.” The lawsuit was filed in the U.S. District Court for the Northern District of California.
“Anthropic’s contracts with the federal government are already being canceled. Current and future contracts with private parties are also in doubt, jeopardizing hundreds of millions of dollars in the near-term,” the filing says. “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.”
On Thursday, Anthropic confirmed that it had officially been designated a supply chain risk, an extraordinary move that has historically been reserved for foreign adversaries. It will require require defense vendors and contractors to certify that they don’t use Anthropic’s models in their work with the Pentagon.
President Donald Trump also shared a post on social media last month directing federal agencies to “immediately cease” all use of Anthropic’s technology.
“WE will decide the fate of our Country — NOT some out-of-control, Radical Left AI company run by people who have no idea what the real World is all about,” Trump wrote.
