Artificial intelligence company Anthropic filed a lawsuit Monday in federal court in California against the Defense Department and other federal agencies, challenging the government's designation of the company as a supply chain risk.

The lawsuit argues that the Pentagon's decision to label Anthropic and its products as a supply chain risk, along with President Trump's order directing all federal agencies to cease using Anthropic's services, are "unprecedented and unlawful."

According to court filings, the supply chain risk designation came after negotiations between Anthropic and the government over safety guardrails broke down earlier this month. The specific details of those negotiations were not disclosed in the available information.

The legal action targets both the Defense Department's classification decision and the broader administrative directive prohibiting federal agencies from utilizing Anthropic's artificial intelligence products and services.

Anthropicis seeking judicial review of the government's actions through the federal court system. The company has not publicly detailed what specific remedies it is seeking beyond challenging the designation and usage restrictions.
