Acton's win settles an Ohio governor board that had made her a five-in-six favorite

Democrat Amy Acton won the race for Ohio governor on Tuesday, November 3, The Associated Press projected at 10:49 p.m. that night, and the Ohio Secretary of State's unofficial results, read at 9:55 a.m. Eastern on November 5, 2026, show her ahead of Republican Vivek Ramaswamy by 364,448 votes with every one of the state's 8,834 precincts reporting. Ramaswamy conceded in Columbus on election night. The result matched the side both prediction markets had priced as the clear favorite going into the vote, and it came in wider than the market's own price implied a close race would be.

The count on November 5, 2026 stood at 2,404,178 votes for Acton and her running mate, David Pepper, against 2,039,730 for Ramaswamy and Robert A. McColley, or 52.3% to 44.4%, with Libertarian Don Kissick at 3.3%, which leaves Acton ahead by nearly eight points of the vote. It is the first time in 20 years that Ohio voters have elected a Democrat to lead the state, the Ohio Capital Journal reported. These are unofficial results, and Ohio's canvass, not the election-night count, produces the official figure.

What the Ohio governor market had priced

Both venues went into Election Day with the same number. On the evening of November 2, 2026, the last reading before polls opened, Kalshi and Polymarket each had the Democratic side of the Ohio governor's race at 83% and the Republican side at 18%. That price treated an Acton win as roughly a five-in-six outcome and left Ramaswamy about a one-in-six chance of an upset: a firm favorite, with real room left for an upset. It had climbed there over three weeks, from 69% on both venues on October 12, 2026 to 83% on both on November 2, 2026, which means the market spent October moving from a lean toward a clear call; the low point of the closing stretch was Polymarket's 79% on October 29, 2026, after a poll that narrowed Acton's lead.

The board has since closed out the question. In the November 5, 2026 read, Kalshi and Polymarket both quoted the Democratic contract at 100% and the Republican contract at 0%, and the board is listed as resolved. That last price means the market is recording the call rather than forecasting anything, and it says nothing on its own about when either venue pays out; each venue settles under its own rules. Trading through the night was heavy: Kalshi's board had changed hands on about 17.7 million contracts in its lifetime, and Polymarket's Democratic side alone had drawn about $1.53M, each venue in its own unit.

Why the result reads as a market that was right but cautious

A price of 83% is a statement about uncertainty, not a margin, which means it should be judged on whether the favorite won and whether anything in the count suggested the race was closer than the price allowed. The market was right about the winner, and the size of the win, close to eight points in the unofficial count, sits at the comfortable end of what an 83% favorite implies. What the 18% on Ramaswamy was paying for was the chance that the late polling was wrong or that the closing weeks of the campaign moved votes the polls did not catch. Neither happened in a way the count shows. The Ohio Capital Journal reported that Ramaswamy ran behind every other member of the Republican statewide ticket, and that Acton's campaign had stayed on affordability while the race's final week was dominated by an attack ad featuring her estranged mother, which Ramaswamy's campaign acknowledged making.

The earlier coverage on this site traced how the price got to 83%: the poll-driven climb through October, the late Suffolk dip and the final pre-election poll. The result is the test those prices were waiting for, and the closing number held up.

Where Acton's margin came from

The county returns show how the statewide lead was built. Acton carried 15 of Ohio's 88 counties in the unofficial count, and three of them did most of the work: she won Franklin County by 232,232 votes, Cuyahoga County by 223,077 and Hamilton County by 97,928. Those three margins add to 553,237 votes, more than her statewide lead, which means Ramaswamy won the other 85 counties combined by 188,789 votes and still lost the state.

The rest of Acton's counties fill in the map around the cities and their suburbs. She won Summit County by 58,210 votes, Lucas by 44,705, Montgomery by 36,430 and Lorain by 18,149, and she carried Delaware County, north of Columbus, by 9,662 votes and Lake County by 5,369. Mahoning, Trumbull, Portage, Wood, Erie and Athens counties complete her list. Ramaswamy's largest county margins came in Warren County, by 17,523 votes, and Butler County, by 11,320, and he carried Stark County by 2,939.

The county map matters for what the market got right. A price of 83% on a statewide race is a bet on the total, not on any county, and the unofficial count shows a total that did not depend on a single close county to hold: no county's outstanding provisional ballots approach the statewide margin.

What else Tuesday changed in Columbus

Acton takes office with a Republican-controlled General Assembly, but not the one Ohio has had. Democrats won enough Ohio House seats to break the Republican supermajority, the Ohio Capital Journal reported on November 4: unofficial results showed 42 Democrats and 52 Republicans elected to the 99-seat chamber, with five races still too close to call that afternoon, below the 60 seats a supermajority requires. In the Ohio Senate, Republicans kept their supermajority, with 22 Republicans and 11 Democrats elected. The practical consequence is that a veto from the new governor is harder for the House to override than it would have been at any point since 2013.

The Secretary of State's count shows 4,658,250 ballots cast against 8,018,054 registered voters, which is 58.1% of the rolls. Democrats also won the secretary of state's race on the same ballot, which means the office that oversees Ohio's canvass changes parties when Allison Russo takes office.

What happens next

The count is not finished, but nothing outstanding is large enough to change this race. The Secretary of State's results page lists 102,148 outstanding ballots statewide as of November 5, 2026: 3,779 absentee ballots from military and overseas voters and 98,369 provisional ballots. That is under a third of Acton's margin. Mailed ballots from military and overseas voters have up to four days after Election Day to arrive at the county boards, which runs through November 7, and the bipartisan county boards decide which provisional ballots count during the official canvass.

The Secretary of State says the official canvass is completed about three weeks after the election, and the results are released after the office reviews the county boards' canvass reports; it has not published a certification date on its results page. A statewide race goes to an automatic recount only when the margin is under one-fourth of one percent of the vote, and this one is roughly thirty times that. The Ohio governor market page carries the board and its resolution rules, and the elections page collects every Ohio race the markets priced.
