This market will resolve according to the candidate who wins the nomination for the Republican Party to contest the OH-09 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Republican primary will take place on May 5, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Republican sources, including https://www.rnc.org/. Any replacement of the nominee before election day will not change the resolution of the market.Derek Merrin's 82.5% implied probability in the OH-09 Republican primary trader consensus reflects his dominant 33% showing in the mid-April JL Partners poll of likely voters—nearly triple Josh Williams' 14%—bolstered by the National Republican Congressional Committee's endorsement and prior name recognition from challenging Rep. Marcy Kaptur. Williams trails at 16.2% with backing from Rep. Jim Jordan and claims of leading Q4 fundraising, appealing to grassroots conservatives amid 40% undecideds. An April 20 debate among all five candidates, including Madison Sheahan at 2.4%, focused on immigration and foreign policy but showed no polling shift. With the May 5 primary five days away, traders anticipate undecideds breaking toward the frontrunner in this redrawn battleground district.
