# Pentagon designates Anthropic a "supply chain risk" after it refuses surveillance and autonomous-weapons uses

In late February to early March 2026, Defense Secretary Pete Hegseth labeled Anthropic a 'supply chain risk' after the company refused to let Claude be used for mass surveillance of Americans or autonomous lethal weapons. The administration ordered agencies to phase Claude out. Anthropic sued on March 9 and won a preliminary injunction on March 26.

## Key facts
- Designation dated Feb 27, 2026 per Wikipedia; TechCrunch and CNN describe it as early March — exact date uncertain
- Trigger: Anthropic's refusal to allow mass domestic surveillance and autonomous lethal weapons uses
- Federal agencies directed to phase out Claude over 6 months
- Anthropic sued the Defense Department on March 9, 2026; Judge Rita F. Lin granted a preliminary injunction March 26
- Administration appealed (Axios, April 2, 2026)

## What happened

The dispute began over Anthropic's usage-policy limits on military uses. Wikipedia reports that Hegseth threatened removal from the DoD supply chain before making the designation. Tech companies filed amicus briefs backing Anthropic.

## Why it matters

This was the most serious clash yet between a US frontier lab's safety or usage policies and the federal government. Later rulings split: Judge Lin found the designation unlawful on Aug 27, and the D.C. Circuit upheld a parallel designation on Sept 25.
