    Will a Millennium Prize be awarded for any unsolved Millennium Prize Problem before Jan 1, 2028?
    Outcome
    Before 2028
    Rules

    If the Clay Mathematics Institute officially announces the award of a Millennium Prize for any unsolved Millennium Prize Problem before Jan 1, 2028, then the market resolves to Yes.

    More rules

    The Clay Mathematics Institute must officially announce that a Millennium Prize has been awarded for the complete solution of the specified problem. The solution must be a positive proof as originally stated, not a counterexample or disproof (unless the market specifically includes counterexamples). Announcements of submitted solutions, peer-reviewed publications without CMI verification, or partial solutions do not qualify. If a mathematician solves a problem but declines the monetary prize, the market still resolves to Yes if CMI officially announces the prize award. The Poincaré Conjecture has already been solved by Grigori Perelman.
