This market resolves on the party winning Ohio's 15th congressional district seat in the 2026 midterms. The rules clearly define how party affiliation is determined, including fallback rules for independent candidates based on stated intent to caucus. Resolution relies initially on a consensus of credible reporting, with an official fallback to the Federal Election Commission if any ambiguity arises. While relying on reporting consensus involves some discretion before official certification, congressional race outcomes are standard and unambiguous, presenting minimal risk of unexpected resolution.

Resolution rules

This market will resolve according to the party of the candidate who wins the OH-15 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 3, 2026. ​A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources. This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
