AnthropicAI has reinstated access to its AI models, Fable 5 and Mythos 5, following the U.S. government’s decision to lift export controls. This move comes after an 18-day restriction, reportedly due to national security concerns, was lifted on June 30, 2026. The Fable 5 model is now available globally, while Mythos 5 is selectively restored to approximately 100 approved U.S. organizations dealing with critical infrastructure. The export controls were initially imposed to address security risks, but Anthropic’s implementation of new cybersecurity classifiers appears to have satisfied governmental requirements.
Key Takeaways
- Market activity suggests support for the YES outcome following the restoration of Claude Fable 5, with significant increases in confidence reflected in the market.
- Pricing for the July 1 market suggests a high likelihood of restoration, with the YES probability rising significantly in recent days.
- The lifting of export controls by the U.S. government is consistent with increased market confidence in the restoration scenario.
What to Watch
Developments over the next few days could further impact market pricing. Watch for any additional announcements from AnthropicAI or U.S. government officials that might affect broader access to Mythos 5. Any updates regarding the ongoing negotiations for broader distribution of Mythos 5 could influence future pricing scenarios. Key actors to watch include Anthropic’s CEO Dario Amodei and U.S. AI Adviser David Sacks.
