Ohio prediction market guides follow an Ohio contract from the rule an exchange wrote to the record that settles it. Standing is a separate question, answered on the legal status page.
Ohio election markets settle when each contract's own rule is met. On the 2026 Ohio races, that rule let a media race call pay out weeks before the state's certified count.
· Read guide →The Bengals playoff contract settles the moment Cincinnati clinches a place in the NFL's postseason field or is eliminated from it, which can come before the final week. Seed does not matter.
· Read guide →The Ohio gas price contract works as a column of separate yes-or-no rungs, each asking whether AAA's statewide average for regular gas lands above one price. Every rung under the figure pays.
· Read guide →Ohio's Casino Control Commission says sports-event contracts on prediction markets need an Ohio sports gaming license, and federal courts have declined to block that law against Kalshi. This page reports the filings without a conclusion.
Status as of November 6, 2026 · · See the record →Ohio's Casino Control Commission has demanded that Kalshi stop offering sports-event contracts without a state license, and federal courts have refused Kalshi a preliminary injunction against Ohio's law. This page follows that dispute.
Status as of November 6, 2026 · · See the record →Each guide here takes a contract an Ohio reader meets on this site and follows it from the rule an exchange wrote to the record that ends it. The gas contract is a column of separate thresholds on one AAA figure, the statewide average for regular gasoline, and every rung under that figure pays. The Bengals playoff contract asks only whether Cincinnati is in the NFL's postseason field, so a clinch or an elimination can settle it with games still on the schedule. A race contract on the governor's office or a congressional district can settle on a media race call long before Ohio's county boards finish counting. Guides are listed alphabetically by title. The contracts themselves sit in the markets catalogue, the daily gas board on the Ohio gas prices page, and the state's races on the elections hub.
A guide is added when a mechanic needs its own page rather than a paragraph on a market page, so this index grows slowly. Three kinds of event move it. The calendar is one: the November 3, 2026 general election turned Ohio's race contracts from priced questions into settled ones, and each league's season does the same for the club contracts when its field is set. A rulebook is another, because an exchange can rewrite the source, the deadline or the fallback a contract settles against, and a guide is read again when that happens. The state record is the third. What the courts and the Ohio Casino Control Commission have said about the exchanges is kept, with its dates, on the legal status page, never summarized inside a how-to.
A price on a binary contract is the level at which its Yes side last changed hands, read as an implied probability of one stated outcome. It is not a forecast from this site and not a tip, and the outcome it describes is fixed in a rule written before the first trade. That rule always ends on a document: AAA's published average for a named date, the field a league declares, a set of media calls or a certified count. Two exchanges can list what looks like the same Ohio question and settle it on different documents, which is why a guide reads each venue's rule on its own terms and recommends neither. Nothing in these guides is legal or financial advice.
On the record each contract names. The Ohio gas contract settles on AAA's statewide average for regular gasoline on the named date, the Bengals playoff contract on the NFL's postseason field, and the 2026 race contracts on media race calls, with Ohio's certified count as a fallback.
It is the level at which the Yes side of one contract last traded, read as an implied probability of the outcome the contract's rule states. It is not a forecast from Ohio Predictions and not a recommendation on any side.
Because its rule allows it. Kalshi's House terms permit early resolution once four of eight named news outlets call a race, while Ohio's county boards have until the twenty-first day after the election to finish their official canvass.
On Kalshi and Polymarket, the two exchanges whose contracts the Ohio guides explain, sometimes both on one question and sometimes only one, as with Ohio's daily gas contract on Kalshi. The guides name the venue behind a rule and favor neither.
The legal status page on Ohio Predictions sets out what Ohio law, the courts and the Ohio Casino Control Commission have said about the exchanges, with the date on each part of it. The guides draw no conclusion and are not legal or financial advice.
