A federal judge in the United States has ruled that the Trump administration must rescind a ban on the use of Anthropic PBC's artificial intelligence technology by federal agencies. The ruling, delivered Thursday evening by U.S. District Judge Rita F. Lin in San Francisco, sided with the developer of the Claude chatbot in its lawsuit against the Department of Defense.

The decision marks a significant legal win for Anthropic, which had challenged the government's directive as part of broader scrutiny over supply chain vulnerabilities. Judge Lin's order compels the administration to reverse the prohibition, a move that could have broader implications for how AI firms engage with federal clients.

This outcome underscores the ongoing tensions between national security concerns and the rapid commercialization of advanced AI systems. Anthropic's case centered on whether the risk designation was justified, with the court ultimately finding in favor of the company's position.
