This market resolves based on which party wins the OH-10 congressional district in the 2026 midterm elections. Initial resolution relies on a consensus of credible reporting, with the Federal Election Commission serving as an official fallback if ambiguity arises. The rules explicitly handle independent or third-party candidates by attributing them to the party they intend to caucus with at the time all House races are called. Election results may take days or weeks to finalize depending on counting speed and close margins, but the fallback to official federal election certification provides a clear ultimate backstop.

Resolution rules

This market will resolve according to the party of the candidate who wins the OH-10 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/).
