Anthropic Sues U.S. Government Over National Security Blacklist
Anthropic is suing the U.S. government to overturn a supply-chain risk designation issued after the company refused to remove AI safety guardrails for military use.
The United States Department of War (formerly the Department of Defense) designated AI startup Anthropic as a national security supply-chain risk in early March 2026. The move followed a collapse in negotiations after Anthropic CEO Dario Amodei refused a Pentagon ultimatum to remove safety guardrails prohibiting the use of the Claude AI model for mass domestic surveillance and fully autonomous weapons. President Donald Trump subsequently ordered all federal agencies to cease using Anthropic's technology, granting the military a six-month phase-out period.
Anthropic filed two federal lawsuits in California and Washington, D.C., alleging the designation is an unlawful campaign of retaliation and a violation of First and Fifth Amendment rights. The company argues the label, typically reserved for foreign adversaries, could cost it billions in revenue. In response, the Department of Justice claimed the designation is a commercial dispute, alleging Anthropic could sabotage or manipulate models during active combat operations to satisfy corporate interests.
Despite the ban, reports indicate the military continued using Claude for target identification and intelligence during strikes in Iran. The Pentagon has since shifted its classified AI needs to competitors OpenAI and xAI, who agreed to terms allowing all lawful military use. Major tech partners including Microsoft, Google, and Amazon have continued providing Claude to non-defense customers. During a March 24 hearing, U.S. District Judge Rita F. Lin questioned the government's motives, suggesting the actions looked like an attempt to cripple the company.
