• A federal appeals court upheld the Pentagon's designation of Anthropic as a national security risk.
• The ruling blocks Anthropic's AI models from being used by the US military and contractors.
• The court found the Department of Defense had ample support for its determination.

This ruling may indicate a growing trend of the US government scrutinizing AI companies for national security risks, which could have significant implications for the industry. The decision suggests that the executive branch has considerable power to blacklist US businesses, potentially impacting the development and deployment of AI technologies.
