Resolution Rules

Resolves Yes if …

This market will resolve according to the winner of the 2026 midterm Illinois U.S. Senate election, inclusive of any run-offs. A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date. Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.

Resolves No if …

No otherwise — if the Yes condition is not satisfied by the resolution criteria.

Important caveats

This market resolves according to the source market rules. Review the source market before relying on this interpretation.
