After Anthropic refused to let Claude be used for fully autonomous weapons and mass surveillance of Americans, the Pentagon officially declares it a "supply chain risk", a first for an American company.
What changes
- On March 5, 2026, the Pentagon notifies Anthropic that the company and its products are a supply chain risk, effective immediately.
- Defense contractors can no longer use Claude in their work for the department.
- On March 26, Judge Rita Lin (San Francisco) suspends the measure, then rules it unlawful on August 27.
- On September 25, the D.C. Circuit Court of Appeals upholds 2-1 the second designation, based on a different legal authority.
- Anthropic is considering a rehearing or an appeal to the Supreme Court.
On March 5, 2026, the U.S. Department of Defense (renamed "Department of War" by the Trump administration) officially informs Anthropic that the company and its products are "deemed a supply chain risk, effective immediately." It is the first time an American company publicly receives this label, usually reserved for foreign adversaries. ### What happened - Anthropic had signed a 200 million USD contract with the Pentagon in July 2025. Negotiations over Claude's deployment stalled on two red lines: no mass surveillance of Americans, no fully autonomous weapons without a human in the firing decision. - The Pentagon demands use "for all lawful purposes." On February 27, Donald Trump orders federal agencies to stop using Claude and Pete Hegseth announces the designation; the formal notification follows on March 5. - The designation bars defense contractors from using Anthropic's models in their work for the department. ### Legal follow-up | Date | Step | |---|---| | March 9, 2026 | Anthropic sues in San Francisco and before the D.C. Circuit Court of Appeals (two distinct designations) | | March 26, 2026 | Judge Rita Lin grants a preliminary injunction: the measures "appear designed to punish Anthropic" | | August 27, 2026 | The same judge rules the designation unlawful, in violation of the First Amendment | | September 25, 2026 | The D.C. Circuit upholds the second designation 2-1 | In the appeals ruling, Judge Gregory Katsas writes that "it is the President and the Secretary of War who must determine how best to balance the competing risks." Judge Karen LeCraft Henderson dissents. The court stays its decision to allow a petition for rehearing. ### Caveats The two courts reach opposite conclusions on two different legal bases. Until the Washington case is finally resolved, Anthropic technically remains designated a risk, according to CNBC. ### Key takeaways The dispute raises an unprecedented question: can an AI provider impose usage limits on its own country's military? The final answer may come from the Supreme Court.
