Anthropic spent the better part of June watching its newest AI models sit idle for international users, blocked by a U.S. government export control order. On June 30, that block was lifted, and the company can now move forward with global deployment, just in time for what could be one of the most closely watched tech IPOs of the year.
The clearance covers Fable 5 and Mythos 5, two frontier models Anthropic launched as part of its Mythos class series in June 2026. The U.S. Commerce Department had issued an export control directive on June 12 that barred foreign nationals from accessing either model, citing national security concerns tied to a potential jailbreak vulnerability. Anthropic had to disable the models globally just days after launch. For a company that filed a confidential S-1 registration with the SEC on June 1, the timing was about as welcome as a fire alarm during a job interview.
What the clearance actually means
Fable 5 is scheduled for global redeployment on July 1. Mythos 5 takes a narrower path: it will be available exclusively to approved U.S. organizations, suggesting the government still has reservations about that particular variant’s international exposure.
The practical consequence of the original ban showed up almost immediately in pre-IPO trading. Perpetual contracts tied to Anthropic on the Hyperliquid exchange dropped roughly 3.7% following the export control order.
