Anthropic Keeps Mythos 5 Offline for 14 Days as Trump Export Order Stalls Talks
3 articles · Updated · The Verge · Jun 26
Summary
Fourteen days after the June 12 order, Anthropic still has no timeline to restore Mythos 5 and Fable 5, saying negotiations with the Trump administration remain unresolved.
The White House demanded Anthropic block “any foreign national” from the models over security concerns, and the company has concluded its only workable option is to keep them fully offline.
One obstacle is the lack of a clear export-control framework for AI systems: Commerce had reportedly tested Fable 5 before release, then moved only after a reported guardrail-bypass concern surfaced.
The shutdown is hitting Anthropic’s business ahead of an IPO, threatening revenue from premium models needed to support heavy compute commitments including a $15 billion-a-year SpaceX data-center deal.
The standoff is also chilling the wider US AI market, raising fears similar controls could spread to OpenAI, Google or Microsoft and pushing some countries to seek non-American AI alternatives.
By restricting its top AI, did the White House just hand the global market over to rival China?

The 2026 Anthropic AI Shutdown: U.S. Government Intervention, Global Tech Sovereignty, and the Future of AI Regulation
Overview
In June 2026, the Trump administration forced Anthropic to disable its most advanced AI models, including Mythos, citing national security concerns. This marked one of the most aggressive uses of export-control powers against a commercial AI product, highlighting the government's struggle to set clear rules for fast-moving AI technology. The shutdown followed a sweeping AI executive order and discussions about using Mythos to strengthen federal cyberdefense. As a result, Anthropic faced a sudden operational halt, disrupting its services and raising urgent questions about the future of AI regulation and industry stability.
