Anthropic sues Pentagon over rare "supply chain risk" label; Axios, March 9, 2026

 Maria Curi, Axios; Anthropic sues Pentagon over rare "supply chain risk" label

"Anthropic on Monday sued the Pentagon, alleging its designation as a "supply chain risk" violates the company's First Amendment rights and exceeds the government's authority.

Why it matters: Supply chain risk designations are usually reserved for foreign adversaries that pose a national security risk — a punishment that could be hard for the government to square as it relied on Claude for operations in Iran.

State of play: The Pentagon last week designated Anthropic a supply chain risk, meaning companies must stop using Claude in cases directly tied to the department.

• President Trump also told the federal government in a Truth Social post to stop using Anthropic's technology, and some agencies have begun offboarding the tools.
• 
  

Anthropic is asking courts to undo the supply chain risk designation, block its enforcement and require federal agencies to withdraw directives to drop the company.

• The company says its two lawsuits are not meant to force the government to work with Anthropic, but prevent officials from blacklisting companies over policy disagreements."
