Federal Appeals Court Upholds Pentagon's Blacklisting of Anthropic AI

• •The Pentagon's blacklisting of Anthropic restricts its AI models from military use.
• •The federal appeals court upheld the DOD's designation citing national security risks.
• •Anthropic is exploring further legal options after the ruling.

A federal appeals court upheld the Pentagon's designation of Anthropic as a supply chain risk, preventing the military and its contractors from using Anthropic's AI models. The ruling, which came on September 25, 2026, is a setback for Anthropic, which had previously won a partial victory in California. The Department of Defense (DOD) labeled Anthropic a supply chain risk in March 2026 after the company refused to allow its AI technology for all lawful purposes, citing ethical concerns. The court found the DOD had sufficient grounds to conclude that Anthropic's AI could pose a national security threat. Anthropic plans to consider further legal options, including a potential appeal to the Supreme Court. The blacklisting significantly jeopardizes Anthropic's business dealings with defense contractors and federal agencies. The ruling highlights ongoing tensions between the government and AI companies regarding the use of advanced technologies in military applications.
