Designation

• Anthropic filed a lawsuit in San Francisco federal court on March 24, 2026, urging a judge to block the Pentagon's designation of the AI firm as a supply-chain risk. • The company described the label as 'unprecedented and stigmatizing,' amid a feud with the Trump administration over potential AI use in warfare. • A hearing occurred on Tuesday before Judge Lin, with Anthropic also filing a separate case in Washington, D.C. federal appeals court.

• The Trump administration designated AI company Anthropic as a 'supply chain risk' and ordered federal agencies to stop using its technology, prompting Anthropic to file a lawsuit against the government. • Major tech firms including Google, Microsoft, Meta, and OpenAI have backed Anthropic through amicus briefs and legal support, warning that blacklisting an American company harms U.S. innovation and competitiveness against China. • The conflict stems from late February tensions when Trump publicly criticized Anthropic, leading to contract cancellations and raising concerns about uncertainty throughout the broader technology industry.
