Ohio Governor Race: Prediction Market Shifts in Ramaswamy vs Acton

The race for Ohio governor is intensifying, with Republican candidate Vivek Ramaswamy seeing a decline in his odds against Democrat Amy Acton. On prediction market site Kalshi, Ramaswamy’s chances hit a new low of 43% on Monday. The site reveals Ramaswamy’s odds had previously dipped below Acton’s in April, showed an upswing by May’s end, but lagged again around mid-August, failing to recover since.

Midterm elections often reflect the current political landscape for the ruling party. Traditionally, the president’s party loses seats during these elections. Republicans now maintain a thin majority in both the House and Senate. Donald Trump, who backed Ramaswamy’s gubernatorial bid, won Ohio in the 2024 presidential race against Kamala Harris, with a significant margin.

Newsweek sought comments from Acton and Ramaswamy’s campaigns via email on Monday.

Key Candidates and Context

Ramaswamy and Acton are the primary contenders for governorship as current GOP Governor Mike DeWine approaches a term limit. Acton, having led Ohio’s Department of Health, matches up against Ramaswamy in a state that has recently leaned Republican. Despite twice supporting former President Barack Obama in 2008 and 2012, Ohio swung towards Trump in the last three presidential elections.

Additionally, Democrats experienced a setback when Democratic Senator Sherrod Brown lost his seat to Republican Bernie Moreno.

Democrats’ Objectives

The Democratic party considers Ohio a prime target for gaining seats in the 2026 midterms, aiming for Brown’s Senate seat while eyeing the governorship. Brown confronts GOP Senator Jon Husted in the Senate race. Recent polls depict tight competition, with Acton and Brown often slightly ahead. The Cook Political Report has classified the Senate contest as unpredictable.

Democrats are strategizing on Trump’s low approval ratings, coupled with public dissatisfaction over policies involving immigration, economic challenges, and foreign policy issues, including tensions with Iran.

Prediction Market Insights

On Polymarket, Acton holds a 58% chance of victory, surpassing Ramaswamy’s 41%. Acton has remained ahead since late August. Florida Atlantic University’s political professor Craig Agranoff emphasized the significance of Ramaswamy’s dip on Kalshi. He noted Ohio typically favors Republicans, but the current midterm scenario seems challenging. Agranoff observed prediction markets are increasingly influential among party strategists and donors, however, they are not seen as definitive electoral predictors. He suggested using Kalshi as a preliminary indicator rather than a voter substitute, while sites like PredictionEdge.com gain traction for political forecasting.

Voter Sentiment

A YouGov and Bowling Green State University poll taken between September 1 and 10 shows 48% favoring Acton, against 45% backing Ramaswamy in the governor’s race.

Despite preferences, 62% believe Ramaswamy will win, contrasted with 36% anticipating Acton’s victory and 1% supporting Kissick.

In Fox News’s survey, conducted by Beacon Research and Shaw & Company Research, Ramaswamy leads Acton with 50% versus her 48%. This reflects a change since June, where Acton had a slight advantage.
