polymarket
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/).

recent wire items
- OH-12 House race heavily priced for one outcome Polymarket 94%
- Polymarket prices the OH-12 House Election Winner contract at 94%, reflecting a near-settled race despite procedural uncertainty in the broader midterm environment.
- Voting-rule disputes and Trump's focus on election mechanics introduce tail risk to certifications, but OH-12 at 94% shows the market is not pricing significant result-disruption risk.
- The midterm House turnout contract (CM-EVT-FMNSCSWMC8) saw trading volume surge 43,946% day-over-day, signaling sharp fresh interest in participation-level bets as Election Day approaches.
- Resolves via UMA oracle; settlement requires a certified winner in Ohio's 12th district, meaning post-election legal challenges could delay resolution.
