Greg Landsman holds a strong position as the Democratic incumbent in Ohio's 1st congressional district ahead of the November 3, 2026, general election. The seat's fundamentals, including Landsman's 2024 reelection margin and recent polling averages showing him ahead, underpin trader consensus around his prospects despite a new congressional map that added more Republican-leaning territory in Hamilton, Warren, and Clinton counties. Eric Conroy secured the Republican nomination with a primary victory and former President Trump's endorsement but trails in available surveys. Race ratings from outlets such as the Cook Political Report and Inside Elections classify the contest as lean or tilt Democratic, reflecting the district's competitive but incumbent-favored profile and limited late-cycle shifts in voter sentiment.

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/).
