U.S. restrictions on new Anthropic models could trigger a global AI arms race

Anthropic has blocked access to its Fable 5 and Mythos 5 AI models after the government flagged them as a security threat when used by foreign nationals. The move highlights regulatory and national-security risk around AI model access and distribution. The news is negative for Anthropic operationally, but the likely market impact is limited unless broader restrictions follow.
