Resolution rules

Each outcome is a separate contract with its own rules. The rules for Before 2035:

If the Clay Mathematics Institute officially announces the award of a Millennium Prize for the Riemann hypothesis before Jan 1, 2035, then the market resolves to Yes. 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.
