Top Illinois Prediction Markets
Two families of contract make up the Illinois catalog. The election family asks which party takes an Illinois office on November 3, 2026: the governor's race, the U.S. Senate seat Dick Durbin holds and House seats such as the 8th District. Each of them pays on a party rather than a named candidate.
The sports family follows clubs that play their home games in Illinois. Some contracts are league title fields narrowed to one club, such as the Bulls' NBA Finals market and the Blackhawks' Stanley Cup market. Others are ladders, like the Bears' win total, where every rung asks whether the club reaches a given number of wins. The list on this page runs in order of lifetime trading volume, so the most heavily traded questions come first.
What Moves Illinois Prediction Markets
The election contracts answer to the State Board of Elections' calendar. Early voting at permanent polling places runs from October 19 to November 2, 2026, election authorities finish their canvass by November 24, and the Board proclaims statewide results by December 4. Kalshi settles its Illinois race contracts on the party of the official sworn in or inaugurated, so its payouts come in January 2027 even when a race is called on election night.
The club contracts react to results. Every Bears game reprices the division, the playoff question and each win-total rung at once, until the NFL regular season ends on January 10, 2027. The Fighting Illini and Northwestern close their regular seasons against each other in Evanston on November 28, 2026, and the Big Ten title game follows in Indianapolis on December 5. The NBA and NHL title fields stay open until their playoffs end in 2027.
Why Illinois Prediction Markets
A poll asks people what they think; a prediction market asks traders to pay for a claim. A Yes contract pays a fixed amount if its outcome happens and nothing if it does not, so the price works as the chance traders give that outcome. Kalshi and Polymarket each list many Illinois questions, and their quotes do not always agree. Every figure in this catalog is the cheapest Yes either exchange quotes for that line, with the exchange named beside it, never a blend of the two. Each market page names the venues that price it, quotes the resolution rule in the exchange's own terms and gives the settlement date, so the payout condition is clear before the price is.
Questions readers ask
How do Illinois prediction markets work?
Each contract asks a yes-or-no question about Illinois, such as which party wins the governor's race on November 3, 2026, and pays a fixed amount if the answer is Yes. The price traders pay for that payout reads as the probability they give the outcome.
Which Illinois races and teams have prediction markets?
On the election side, the governor's race, the U.S. Senate race and Illinois's U.S. House districts. On the sports side, the Chicago Bears, Chicago Bulls, Chicago Blackhawks, the Fighting Illini and Northwestern, through title, division, playoff and win-total contracts.
How do Illinois prediction markets settle?
On the event each exchange's rules name. Kalshi's Illinois race contracts pay on the party of the official sworn in or inaugurated; Polymarket's governor market pays on a call by the Associated Press, Fox News and NBC, or on certification; club contracts pay on official league results.
Where can I trade Illinois prediction markets?
Kalshi and Polymarket price most Illinois contracts on this site, while some, including the Bears' playoff question and the Fighting Illini's win total, trade on Kalshi alone. Illinois Predictions shows the prices and takes no trades.
Are prediction markets legal in Illinois?
The legal status page sets out the record with dates: the Illinois Gaming Board's cease-and-desist letters to Kalshi on April 1, 2025 and to Polymarket US on January 27, 2026, and a federal court ruling in Chicago on October 2, 2026. It draws no conclusion and is not legal advice.
