This market will resolve to "Yes" if Anthropic, or an official representative of Anthropic, announces that Anthropic has solved any of the qualifying Millennium Prize Problems by 11:59 PM ET of the date specified in the title. Otherwise, this market will resolve to "No". The qualifying problems are the Riemann Hypothesis, P versus NP, the Yang-Mills existence and mass gap problem, the Hodge Conjecture, and the Birch…

If Anthropic announces a complete solution, developed by Anthropic or researchers collaborating directly with Anthropic on that solution, to one of the six Millennium Prize Problems unsolved as of September 5, 2026 before Jan 1, 2027, then the market resolves to Yes.
Full rules on Kalshi ↗About this market
This market will resolve to "Yes" if Anthropic, or an official representative of Anthropic, announces that Anthropic has solved any of the qualifying Millennium Prize Problems by 11:59 PM ET of the date specified in the title. Otherwise, this market will resolve to "No". The qualifying problems are the Riemann Hypothesis, P versus NP, the Yang-Mills existence and mass gap problem, the Hodge Conjecture, and the Birch and Swinnerton-Dyer Conjecture (https://www.claymath.org/millennium-problems/). Announcements concerning the Navier-Stokes existence and smoothness problem will not qualify. A qualifying announcement must express that the problem has been solved; announcements of partial results or progress toward a solution will not qualify. The announcement must present the solution as the work of Anthropic, its researchers, or its models, alone or jointly with outside researchers. An announcement that only credits or congratulates outside researchers, including researchers who used Anthropic's models, compute, or research credits, will not qualify. No further confirmation from Clay Math Institute or any other organization is required. The primary resolution source for this market will be official information from Anthropic and/or its official representatives; however, a consensus of credible reporting may also be used.
