Market details

Resolution rules

This market will resolve according to the outcome of the United States Senate general elections in Ohio, Iowa, and Maine (including the special election in Ohio) that are currently scheduled for November 3, 2026, inclusive of any potential runoffs. A candidate will be considered to represent a party by their ballot-listed affiliation or if they are the nominee of that party. 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. If the results of one of these elections are not conclusively known by March 31, 2027, or if an independent or third-party candidate wins one of these elections, this market will resolve to "Other". For purposes of this market, a "sweep" is when a party wins all races. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called the relevant elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on the official certification.
