Anthropic, the maker of Claude AI, has taken the Trump administration to court. The AI company has filed a lawsuit on Monday (March 9) to block the Pentagon from placing it on a national security blacklist – a designation that is reserved for those organisations, or countries, that pose national security threat. This is already costing the company government contracts and threatens hundreds of millions of dollars in future business.
The lawsuit has been filed in the US District Court for the Northern District of California and marks another escalation in a standoff between the AI startup and the US military over use of AI for autonomous weapons and domestic surveillance.
What Anthropic has said in lawsuit against Trump administration
The company said in a complaint that these actions are “unprecedented and unlawful,” and that they are “harming Anthropic irreparably. ”
“These actions are unprecedented and unlawful. The Constitution does not allow the government to wield its enormous power to punish a company for its protected speech,” Anthropic said.
“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. All of these unprecedented actions—the Presidential Directive, the Secretarial Order and the Secretarial Letter that followed it, and other agency actions taken in response to the Presidential Directive (collectively, the Challenged Actions)—are harming Anthropic Irreparably,” the company added.
Why Anthropic has sued the government
The Pentagon wanted Anthropic to remove hard limits on deploying its AI for fully autonomous weapons and domestic surveillance of American citizens. Anthropic denied saying that current AI models are not reliable enough for autonomous weapons and that using them in that way would be dangerous. It also called domestic surveillance a violation of fundamental rights.
When those negotiations broke down, Defense Secretary Pete Hegseth formally designated Anthropic a national security supply-chain risk. President Donald Trump then directed the government to stop working with Anthropic altogether, with a six-month phase-out announced for existing contracts.
The Defense Department has been equally firm, saying that US law – not a private company – should determine how America defends itself, and that the military needs full flexibility to use AI for “any lawful use.” The Pentagon warned that Anthropic’s self-imposed restrictions could endanger American lives.
