Anthropic keeps Mythos 5 and Fable 5 offline after June 12 U.S. export control order
An export control order issued by the Trump administration on June 12 required Anthropic to suspend access to Mythos 5 and Fable 5 for all foreign nationals, including employees working in the U.S., leaving the models fully offline for more than 14 days. With talks stalled, the company has been unable to restart the high-margin models, complicating IPO preparations, its ability to cover a $15 billion-per-year SpaceX compute commitment, and its path to profitability. OpenAI was also told to delay the release of GPT-5.6 and accept customer-by-customer approval. The move marks the first U.S. emergency export control applied to AI models, but it has not affected traditional listed stocks or major indexes.
