Anthropic, the artificial intelligence company, has filed two lawsuits against the U.S. Department of Defense (DOD) after the agency labeled the company as a 'supply chain risk'. In one lawsuit filed in San Francisco, Anthropic argues the government is infringing on its free speech rights by punishing the company for its protected speech. The other lawsuit, filed in Washington D.C., accuses the DOD of unfairly discriminating and retaliating against Anthropic. The company is also seeking a temporary restraining order to continue working with its military partners while the legal battles play out.

Why it matters

This dispute highlights the growing tensions between the government and the AI industry, as agencies like the DOD seek to limit their exposure to potential risks from emerging technologies. Anthropic's lawsuits challenge the DOD's authority to designate private companies as security threats, which could have major implications for other AI firms working with the military.

The details

In its lawsuits, Anthropic alleges the DOD's 'supply chain risk' designation is retaliation for the company's public criticism of the government's AI policies. The company claims the DOD is unfairly punishing it by blocking Anthropic from lucrative military contracts. Anthropic is seeking to have the 'supply chain risk' label removed and regain access to its existing DOD partnerships.

• On March 6, 2026, the DOD designated Anthropic as a 'supply chain risk'.
• On March 12, 2026, Anthropic filed two lawsuits against the DOD in San Francisco and Washington D.C.

What’s next

The courts will now have to decide whether the DOD's 'supply chain risk' designation of Anthropic was justified or an unconstitutional infringement on the company's free speech rights. The outcome of these lawsuits could set an important precedent for how the government can restrict private companies' involvement in national security matters.
