OpenAI announces another Millennium Prize solution by...?

This event tracks whether OpenAI will officially announce that it has solved any qualifying Millennium Prize Problem by specific cutoff dates. Each market corresponds to a distinct calendar deadline.

How the outcomes relate

The event consists of a ladder of cumulative time-based deadlines. Because an announcement made by an earlier date also satisfies later deadlines, more than one market can resolve Yes.

How it resolves

A market resolves to Yes if OpenAI or its official representative announces that OpenAI (its researchers, models, or joint efforts) has solved a qualifying Millennium Prize Problem between market creation and the specified date at 11:59 PM ET. Qualifying problems include the Riemann Hypothesis, P versus NP, Yang-Mills existence and mass gap, Hodge Conjecture, and Birch and Swinnerton-Dyer Conjecture. Announcements regarding Navier-Stokes, partial progress, or purely outside researchers do not qualify. No confirmation from the Clay Mathematics Institute is required. If no qualifying announcement is made by the deadline, the market resolves to No.

Key dates

• First deadline: Dec 31, 2026 — 11:59 PM ET
• Second deadline: Dec 31, 2027 — 11:59 PM ET

Resolution source

Official information from OpenAI and/or its official representatives, or a consensus of credible reporting.
