On June 18, 2026, Anthropic received an export control directive from the Trump administration ordering it to suspend access to its newest Claude models, Fable 5 and Mythos 5, for all foreign nationals, including foreign national employees at Anthropic itself (CNBC). The order, issued without specific explanation beyond 'national security authorities,' effectively bars non-US persons from using or accessing Anthropic's frontier models. Senior Anthropic staff flew to Washington to negotiate, but the models remain offline pending resolution (Bloomberg). The crackdown follows a broader US government push to tighten AI export controls, and has left allies like South Korea caught in the crossfire (The Diplomat). This directive significantly hampers Anthropic's ability to serve international customers and collaborate with global talent, directly impacting its revenue and competitive position in the AI infrastructure race. The timing also coincides with Anthropic's accusation that Alibaba orchestrated a massive distillation attack using 25,000 fraudulent accounts to extract Claude capabilities (CNBC), further straining US-China AI tensions. The export restriction is a clear negative for Anthropic, as it limits market access and creates operational uncertainty.
