This market resolves according to the party affiliation of the winning candidate for Ohio's 12th congressional district in the November 2026 midterm elections. Resolution relies on a consensus of credible media reporting, which leaves some latitude to the resolver, but the rules provide a clear fallback to official results from the Federal Election Commission if reporting is contested or ambiguous. Clear mechanics are included to classify independent or non-major-party winners according to their stated intent to caucus at the time all House races are determined.

Resolution rules

This market will resolve according to the party of the candidate who wins the OH-12 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/).
