Ohio elects a new governor on November 3, 2026. Republican Mike DeWine is term-limited, and the race is between Democrat Amy Acton, the state’s former health director, and Republican Vivek Ramaswamy. These are the live odds from Polymarket and Kalshi side by side, plus Ohio’s Senate special election on the same ballot.

The campaign so far
Acton led most public polls through October, though by varying margins, and at least one October poll showed Ramaswamy narrowly ahead. Ramaswamy and his allies have heavily outspent her on advertising, including millions of his own money, and Acton declined to debate him. Ohio has elected Republican governors in every race since 2010. Checked October 2026 against recent reporting.
Ohio Senate special election
Ohio also votes for a senator on the same day. Republican Jon Husted, appointed to the seat J.D. Vance left when he became vice president, faces former Democratic Sen. Sherrod Brown. The winner serves the rest of Vance’s term, which ends in January 2029, so the seat is up again in 2028.

How these markets settle
- Polymarket resolves once the Associated Press, Fox News and NBC have all called the race for the same candidate, or on the official certified result if they haven’t.
- Kalshi’s governor market settles on the party of the governor inaugurated after the 2026 election, but can settle early once a consensus of media organisations projects the winner. Its Senate market works the same way, based on who is sworn in.
Rules as published on each market, checked October 2026. Until a market settles, a price near $1 is still a tradeable position, not a payout.
