This market will resolve according to the winner of the 2026 Ohio U.S. Senate special election currently scheduled for November 3, inclusive of any run-offs. A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date. Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party. The candidates may be named in the contract for the convenience of traders. In the event that any named candidate is replaced as the nominee of their respective party prior to election day, the name in the contract will be updated and the market will resolve based on the replacement nominee of the party. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.

Currently, prediction market odds suggest a different outlook than traditional polling averages for the Ohio Senate election. While polls often show a close race, this market reflects the aggregated predictions of individuals trading on Opinion. It’s common to see discrepancies between prediction markets and polls, as markets incorporate not just voter preference but also factors like turnout likelihood, strategic voting, and information revealed after polls are conducted. This difference can be a valuable signal for understanding the nuances of the election.
On Opinion, this market is priced through a continuous order book where traders buy and sell contracts representing each possible outcome of the Ohio Senate election. The price of a contract reflects the market’s implied probability of that outcome occurring. On Opinion, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The more traders believe an outcome is likely, the higher the price of its corresponding contract will be. This dynamic pricing mechanism allows the market to quickly incorporate new information and adjust predictions accordingly, offering a distinct perspective compared to static polling data.
This market resolves around Nov 4, 2026, with the outcome confirmed once the winner of the Ohio Senate election is verifiable from credible public reporting. The resolution will be based on the official results certified by election authorities. Traders will then be able to collect payouts based on the outcome they predicted when they purchased contracts on Opinion. It’s important to monitor news sources leading up to and following the election date for updates on the official results and the market’s resolution.
Several signals or events could significantly move this market before its resolution on Nov 4, 2026. Major developments in the campaigns, such as significant fundraising announcements, endorsements from prominent figures, or impactful debate performances, could shift trader sentiment. Unexpected economic news or national political events could also influence perceptions of the candidates’ chances. Furthermore, any changes in polling data, particularly if they indicate a substantial shift in voter preferences, would likely be reflected in the prices on Opinion.
