A federal appeals court on Wednesday denied Anthropic's request for relief from the Defense Department declaring the company a supply-chain risk, complicating the legal battle between the U.S. government and one of the country's leading artificial-intelligence companies. While Anthropic has sustained financial harm from the Pentagon's actions, the appeals court said that it didn't feel strongly enough to override the government on a matter of national security.

Why it matters

This case highlights the growing tensions between the U.S. government and the AI industry, as federal agencies seek to limit the use of certain technologies deemed potential national security risks. Anthropic's legal battles could set precedents around the government's ability to restrict private companies in the name of national security.

The details

The Defense Department has declared Anthropic a supply-chain risk, barring federal agencies from using the company's AI models. Anthropic has filed two separate legal challenges - one against the Pentagon's actions and another against a broader Trump-era ban on federal use of Anthropic's technology. While a California court recently granted Anthropic a preliminary injunction on the broader ban, the appeals court in Washington denied the company's request to be removed from the Pentagon's blacklist.

  • The appeals court ruling was issued on Wednesday, April 8, 2026.
