Anthropic sues Trump administration seeking to undo ‘supply chain risk’ designation

Anthropic sues the Trump administration to reverse its "supply chain risk" designation over military use restrictions on its AI technology.

Anthropic is suing the Trump administration, asking federal courts to reverse the Pentagon’s decision designating the artificial intelligence company a “supply chain risk” over its refusal to allow unrestricted military use of its technology.

Anthropic filed two separate lawsuits on Monday (March 9, 2026), one in California federal court and another in the federal appeals court in Washington, D.C., each challenging different aspects of the Pentagon’s actions against the company.

The Pentagon last week formally designated the San Francisco tech company a supply chain risk after an unusually public dispute over how its AI chatbot Claude could be used in warfare.

“These actions are unprecedented and unlawful,” Anthropic’s lawsuit says. “The Constitution does not allow the government to wield its enormous power to punish a company for its protected speech. No federal statute authorises the actions taken here. Anthropic turns to the judiciary as a last resort to vindicate its rights and halt the Executive’s unlawful campaign of retaliation.”

The Defence Department declined to comment on Monday (March 9, 2026), citing a policy of not commenting on matters in litigation.
