Ohio Governor Race 2026 — Odds

OH · GovernorLean ROpen seat
Incumbent:Open seat

Mike DeWine is term-limited, and Trump-endorsed Vivek Ramaswamy cleared the Republican field while former health director Amy Acton carries the Democratic banner. Ohio's Republican baseline favors Ramaswamy, but markets price him only around 55 percent — a notably thin edge for a red state. Paired with the Husted-Brown Senate special, Ohio is the densest cluster of 2026 election markets anywhere.
