π¨ BREAKING: U.S. Pulls the Plug on Claude β Fable 5 & Mythos 5 Shut Down Worldwide
At 5:21 PM ET on June 12, the U.S. Commerce Department issued an export control directive forcing Anthropic to shut down Fable 5 and Mythos 5 globally β the first time U.S. export controls have been used against a deployed commercial AI model. Three days after launch, hundreds of millions of users hit a wall. Anthropic's $965B IPO is now under a regulatory cloud. #AILeague
What just happened
Why this is unprecedented
The backstory: Anthropic vs. Trump
- February 2026: Trump ordered all federal agencies to stop using Anthropic's models after contract negotiations collapsed. The sticking point was the Pentagon's demand that any AI it purchases be usable "for any lawful purpose" β including autonomous weapons and mass domestic surveillance. Anthropic sought exemptions. The White House said no.
- March 2026: The Pentagon declared Anthropic a "supply chain risk" β a designation historically reserved for foreign adversaries. Defense contractors were required to certify they would not use Claude for government work. Anthropic sued to block the blacklisting; litigation is ongoing. 4
- Early June 2026: Trump signed an executive order requiring federal vetting of the most advanced AI systems before public release.
- June 12, 2026: The export control letter arrives.
The IPO problem is now a crisis

Two weeks of AI failure coverage (June 8β21, 2026), 27 items editorially reduced to 17: The US government used ECRA 2018 export controls to pull Anthropic's Claude Fable 5 and Mythos 5 offline three days after launch β the first-ever application to a deployed AI model β triggering a geopolitical and technical firestorm still unresolved at press time.
