This market will resolve according to the winner of the Democratic Primary for United States Senator from Ohio. If no 2026 Ohio Democratic Senate Primary takes place, this market will resolve to "Other". The resolution source for this market will be the first announcement of the results from the Ohio Democratic party, however an overwhelming consensus of credible reporting may suffice.Former Sen. Sherrod Brown commands 99.1% trader consensus to win Ohio's Democratic U.S. Senate primary on May 5, driven by his three-term incumbency record (2007-2025), unmatched name recognition in battleground Ohio, and a dominant $12.5 million fundraising haul reported last week that dwarfs challengers. Rep. Greg Landsman, former Rep. Tim Ryan (2022 nominee), and state Rep. Allison Russo show negligible support without polls, endorsements, or momentum in this special election vacancy from Sen. JD Vance's vice presidency. No developments in the past 30 days have shifted odds; scenarios like a late scandal, health event, or unexpected turnout could challenge, though barriers remain high.
