The new congressional map, enacted via legislative compromise and slightly more favorable to Republicans than prior versions, has made several Democratic-held districts more competitive while preserving a core of five seats. Incumbents Greg Landsman in OH-1, Marcy Kaptur in OH-9, and Emilia Sykes in OH-13 face the steepest challenges from redrawn boundaries that incorporate additional Republican-leaning areas. Trader consensus around five to seven Democratic seats reflects uncertainty over whether a national midterm environment—typically unfavorable to the president's party—will enable Democrats to defend these marginal districts or flip one or two Republican-held seats. Upcoming candidate recruitment, fundraising trends, and any shifts in Ohio-specific polling or turnout patterns could widen or narrow the range before November 2026.

This market will resolve according to the number of seats in the US House of Representatives won by the Democratic Party in Ohio in the 2026 United States midterm election.
All Ohio US House of Representatives elections held as part of the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th congress are included. Special elections to fill a vacancy for the remainder of an unexpired term are not included, whether or not held concurrently with the 2026 United States midterm election. Runoffs for qualifying elections will determine attribution of the relevant seat.
Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation or vacates their seat after the date of the 2026 United States midterm election, the seat is attributed to the party under which the member was elected.
Members of the House elected as independents who formally caucus, or who announce their intent to caucus, with a party prior to the date of the 2026 United States midterm election are included in that party’s count. If the caucus decisions of relevant members of the US House of Representatives elected as independents cannot be determined as of the date of the 2026 United States midterm election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party.
