About this event

This event tracks the outcome of the 2026 U.S. House of Representatives election for Ohio's 9th Congressional District (OH-09), measuring which political party will win the seat in the midterm elections.

How the outcomes relate

The event contains markets representing different political parties competing for the same congressional seat. Because only one candidate wins the seat, at most one market can resolve Yes, while the other resolves No.

How it resolves

Each market resolves to Yes if the candidate affiliated with the specified political party wins the OH-09 seat in the 2026 midterm elections, and No otherwise. A winning candidate's party is determined by their ballot-listed affiliation or by their stated caucus intent if unaffiliated with the Democratic or Republican parties. Resolution is determined by a consensus of credible reporting, with official results from the Federal Election Commission serving as the definitive fallback if ambiguity exists.
