Former Ohio Sen. Sherrod Brown is trying to make a comeback in a state that rejected him two years ago.
Prediction market traders think he has a slight edge, with a little more than a month until the 2026 midterm election.
The former Democratic senator is trading at 58% on Kalshi, where $4.6 million has changed hands, and 57% on Polymarket, with $745,000 in volume. Those prices make Brown the favorite over Republican Sen. Jon Husted, but not by anything like the margin traders are giving former Democratic Gov. Roy Cooper in North Carolina.
That difference fits the polling. A survey of likely Ohio voters conducted Sept. 21-23 put Brown at 45.6% and Husted at 45.3%, a statistical tie. Several other recent polls have shown Brown ahead, while an earlier New York Times/Siena survey gave Husted a three-point lead.
Forecasters continue to rate the race a toss-up.
Brown’s familiar name, Husted’s harder sell
Brown spent three terms in the Senate before losing reelection in 2024. Husted was appointed to the seat vacated by JD Vance when Vance became vice president. The former senator therefore enters the rematch with a kind of recognition the sitting senator is still working to build.
An earlier Emerson poll found 40% of voters were unsure about Husted or had never heard of him, compared with 14% for Brown.
But name recognition is not the same as a majority. Brown lost his seat as Ohio continued moving toward Republicans, and President Donald Trump carried the state by roughly 11 points in 2024. To win it back, Brown needs voters who have supported Republicans at the top of the ticket to choose differently in the Senate.
His campaign is trying to make that choice about household costs. Brown has attacked Husted over health care, energy bills and tax breaks for data centers, while Husted has argued that Brown’s record contributed to higher grocery and electricity prices.
Husted breaks from Trump on prices
Unlike Michael Whatley in North Carolina, who has stuck closely to Trump even as he trails Cooper, Husted has begun acknowledging an economic problem the president’s allies would rather downplay: Ohioans still think prices are too high.
Husted has also called for the Iran war to end as quickly as possible so gas prices can fall. Still, he has not abandoned Trump. The president is expected to campaign for him in Ohio later this week. But Husted is trying to show voters he hears their frustration without losing the Republican base he needs to turn out.
That is a narrower path than Cooper’s apparent advantage in North Carolina. Ohio voters know Brown, but they have also voted against him recently. Husted benefits from the state’s Republican lean, yet must defend a governing record at a moment when affordability is dominating the race.
The markets’ high-50s prices capture that tension. They favor Brown while leaving Husted with a substantial chance to win.
The Senate control math
Ohio is a Republican-held seat Democrats may need to flip to take the Senate.
Republicans hold a 53-47 majority. Democrats need a net gain of four seats, assuming they hold every seat they currently control.
North Carolina looks like their clearest pickup opportunity, with Cooper far ahead in both polls and prediction markets. Maine remains another major target. After that, Democrats still need wins in more difficult territory, and Ohio is one of the most plausible places to find one.
A Brown victory would take a seat from Republicans in a state Trump won comfortably. It would turn his personal political comeback into a potentially decisive Senate pickup. A Husted victory would force Democrats to find that seat elsewhere, perhaps in Alaska, Iowa or Texas, while still protecting their own vulnerable incumbents and open seats.
That is why Ohio matters so much to both parties. North Carolina may be moving toward an early check mark for Democrats. Ohio is the kind of race they still have to earn, and the kind Republicans cannot afford to let slip.
