This market will resolve according to the candidate who wins the nomination for the Republican Party to contest the OH-01 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.Eric Conroy's commanding 97% implied probability in the OH-01 Republican primary stems from Steven Erbeck's April 20 withdrawal citing party unity, following President Trump's April 14 endorsement, alongside backing from House GOP leadership, Rep. Jim Jordan, former Rep. Steve Chabot, and Sen. Jon Husted. Conroy's Air Force and CIA veteran background, combined with superior fundraising—outpacing rivals combined—has consolidated support in this May 5 contest for the GOP nomination to challenge Democratic incumbent Greg Landsman. While Oglesby-Henry holds modest 14% trader odds, an upset would require a late scandal, health issue, or unexpected endorsement shift in the final days.
