Polymarket prices this June 30 at 100%.
Anthropic restored access to its advanced AI model, Claude Mythos 5, by June 30, following the lifting of U.S. government export controls. The decision to renew access to Mythos 5, alongside Claude Fable 5, came after negotiations with the White House, as reported by The New York Times and Business Insider. This move allows partners and clients whose access was previously rescinded to utilize the model once more. The market had strongly favored this outcome, with the odds on "June 30" closing at 100%, indicating high confidence in the restoration.
Background
In April 2026, Anthropic initially released Claude Mythos 5 with limited availability to approved partners within its Project Glasswing security program. However, on June 12, 2026, Anthropic suspended all customer access to Mythos 5 in response to a directive from the U.S. government. This suspension prompted uncertainty regarding when, or if, access would be reinstated, leading to a period of intense negotiation between Anthropic and U.S. authorities.
