Pentagon stops using Anthropic AI tools after blacklisting company

The US Department of Defense has ceased using Anthropic's AI products, an official told the BBC, months after designating the company a national security supply chain risk. Sources said Claude was still used for research, analysis and intelligence gathering, including via Palantir's Maven Smart System, as recently as last week.

• Pentagon labeled Anthropic a supply chain risk in February and set an end-of-August deadline
• Claude was embedded in Palantir's Maven Smart System for intelligence and analysis
• Anthropic is suing the Trump administration to overturn the designation
• The Pentagon has signed contracts with Google, xAI and OpenAI
