SAN FRANCISCO — U.S. District Judge Rita Lin stated on July 30, 2026, that the Trump administration has not presented sufficient evidence to justify banning the federal government from using Anthropic's technology. The judge also stated the administration has not presented sufficient evidence to justify labeling Anthropic a supply-chain risk.

Lin temporarily blocked the ban in March after Anthropic filed two lawsuits against the Department of Defense challenging the ban and risk designation. One of Anthropic's lawsuits against the Department of Defense is being heard in Washington. Lin is now weighing whether to make the temporary blocking order permanent.

The dispute originated from stalled contract negotiations between Anthropic and the Department of Defense. The government argued Anthropic’s public criticism of the Department of Defense justifies the ban. The Department of Defense claimed Anthropic could potentially disable or alter its AI models during warfighting operations.

Lin stated she saw no proof Anthropic could alter a delivered model. I saw no proof Anthropic could flip some kind of kill switch, he said during the court hearing. She called the government's justification logic "really troubling." he warned the government's logic could set a precedent of retaliating against federal contractors who disagree with the administration.

Anthropic stated it did not want its AI used for mass surveillance of Americans. The company also stated it did not want its AI used for targeting or firing decisions involving lethal weapons. Anthropic argued the technology was not ready for such uses.

The Pentagon stated a private company should not dictate how the military uses technologies. The Pentagon stated it would use the tools in lawful ways.

Anthropic had an estimated valuation of $965 billion in May 2026, making it the most valuable pure-play AI company in the world.

The ruling addresses whether the federal government can restrict contracts with technology firms based on public disagreements over policy. Lin's warning about retaliatory precedents shows the stakes for other federal contractors who may oppose administration positions. The case involves the use of artificial intelligence in military operations, a sector where private companies increasingly develop critical tools.
