OpenAI another Millennium Prize claim on Kalshi

If OpenAI announces a complete solution developed by OpenAI or researchers collaborating directly with OpenAI on that solution to one of the five qualifying Millennium Prize Problems (Birch and Swinnerton-Dyer, Hodge, P versus NP, Riemann, or Yang-Mills), excluding the Navier-Stokes existence and smoothness problem and the Poincare conjecture before Jan 1, 2028, then the market resolves to Yes.

Settles on: OpenAI.

No independent base rate yet. Until we connect one (sportsbook consensus, forecasts, the score), the market's own price is the best public forecast, and the fee sits on top of it.

Mostly luck. The market itself expects the favorite to lose this often; the fee is the only certainty.
