How it resolves
Settled by Kalshi, a CFTC-regulated US exchange, against the official source named in each contract (e.g. a government release or election certification), with an Outcome Review Committee as a backstop for disputes.
Resolution criteria
If Anthropic releases a model under Anthropic's Mythos tier — including models branded "Mythos" or "Fable" - excluding Claude Fable 5 (released June 9, 2026) before Sep 1, 2026, then the market resolves to Yes.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.
