[Anthropic Appeal Rejected, Pentagon Maintains 'Supply Chain Risk' Label] On April 9, the U.S. Court of Appeals for the District of Columbia rejected AI company Anthropic's emergency petition, upholding the Department of Defense's designation of Anthropic as a 'national security supply chain risk.' The three judges ruled that the government's interest in regulating AI technology during military conflicts outweighs the potential financial and reputational losses Anthropic may face. This label will prevent Pentagon contractors from using Anthropic's Claude model.
