Ohio Senate Odds Show Brown Lead Increasing: Trade Midterms on Kalshi

• Election Day 2026 is now three weeks away, set for Nov. 3, and several Senate races remain in flux, like Ohio

Ohio has generally been viewed as a purplish state, but the latest Ohio Senate odds show the state could be set for a Blue Wave. The Democrats have had occasional success in recent years, but it has fallen into the category of “We can win it!” for Democrats only to be disappointed when the votes come in. There is no doubt the state has gotten redder, with Republicans having an inherent advantage.

Former Democratic Senator Sherrod Brown, who had served in Washington DC for 18 years, was defeated in 2024 by Republican Bernie Moreno. Although Brown was popular, Republicans rode the coattails of President Trump when he returned to office by defeating Vice President Kamala Harris. Brown was caught in that wave.

Since Trump had selected first-term Senator J.D. Vance as his vice presidential nominee, that seat opened after Trump’s victory. Republican Gov. Mike DeWine named Lieutenant Governor Jon Husted to take Vance’s place. Now, Brown is trying to regain his lost seat against an opponent who was appointed, not elected, and is facing the headwinds of an unhappy electorate that might be nostalgic for a somewhat less contentious political time that the affable Brown exemplified.

Prediction markets are watching the Senate battles closely, and Ohio is one of the more competitive races, giving investors the chance to jump in and profit.

Sherrod Brown

Brown will be 74 years old shortly after Election Day.

He has been in politics in one capacity or another for more than five decades, starting in the Ohio House of Representatives and winning election to the Senate in the Democratic wipeout of the Republicans during the midterms in President George W. Bush’s second term in the White House.

There are parallels between Presidents Trump and Bush with the yoke of unpopular wars and general fatigue with one party dominating the political landscape, leading to the electorate voting against them rather than for the Democrats. In Brown’s favor is that he is a known commodity, is well-liked, has been known as conciliatory with the other party, and would be a safe pick that Ohioans who tend to tilt toward the right can live with.

He is very liberal, which would ordinarily be problematic in Ohio. His positives could outweigh that perception. There were past issues, including being late paying his property taxes and allegations of harassment from his first wife in the late-1980s. She backed off those accusations in later years and held fundraisers for her ex-husband’s first Senate campaign. It’s unlikely that this would have any resonance if brought up in the waning days before the election.

The biggest obstacle he faces is that the state is further to the right in recent years than it was in the past. Trump won Ohio easily in all three of his presidential runs. President Barack Obama won it twice. The margin in 2012 was narrow, 50.7% for Obama to 47.7% for Mitt Romney.

Jon Husted

Husted, 59, was given the Senate seat to replace Vice President Vance. He is a conventionally vanilla Republican who ran for governor before joining rival Mike DeWine’s campaign, where he ultimately became lieutenant governor. Husted is not controversial. In fact, he’s barely noticeable in the Senate since he’s been there for such a short time. He’s married with three children and, in college, turned down an offer to be a college football assistant coach.

For him, the election will come down to how many voters enter the booth and simply flip the switch for the Republican, not knowing or caring about the candidate. A benefit for the GOP is that Gov. DeWine is term-limited, and there will be a new chief executive in the statehouse. Former presidential candidate Vivek Ramaswamy is the Republican candidate against Democrat Amy Acton.

The GOP is pouring money into the gubernatorial race for Trump ally Ramaswamy. Acton is leading in the polls, but her lead mirrors Brown’s lead. Both are well within the margin of error.

Ohio is a safe Republican state when voting for president. Five of the past six governors have been Republicans. More and more, barring a transcendent candidate who does not fit into conventional narratives as Obama did, the state tends to vote for the GOP. That does not bode well for Brown. Nor does the close nature of the race, with all the metrics that would normally point to a blue wave, bode well on Nov. 3.

There is great profit to be made with either candidate, but it is worth the risk to pick Husted to retain his seat, mostly because he’s a Republican and it’s a red state.
