U.S. national security concerns over AI model access threaten Anthropic’s global expansion and raise regulatory risk for U.S. tech firms

Executive summary: The U.S. Commerce Department ordered Anthropic to suspend its Mythos 5 and Fable 5 AI models, citing national security concerns. The decision could limit Anthropic’s ability to sell its models internationally and set a precedent for government control over AI development in the United States.

Who is involved: Anthropic, the U.S. Department of Commerce, and the Trump administration

Likely next: Anthropic may appeal the order, seek clarification on the scope, and other AI firms could face similar restrictions, affecting global AI supply chains.

On June 14, 2026, the U.S. Commerce Department ordered Anthropic to suspend its Mythos 5 and Fable 5 AI models, citing national security. The move, first reported by Le Figaro, marks an unprecedented government intervention in the domestic AI supply chain. It signals a broader willingness of the Trump administration to impose restrictions on advanced AI technologies without detailing the specific security grounds.
