The Only Pritzker-Bailey Debate Replayed 2022, and the Governor Market Treated It That Way
Kalshi and Polymarket both priced a Democratic win at 98% on October 16, 2026, three days after the forum, which means the only Pritzker-Bailey debate was read as a replay of 2022 rather than a turn in the race.

Vancil Says Sorensen Turned Down a Peoria Forum, and the 17th District Board Still Prices a Safe Seat
Kalshi priced a Democratic hold of the 17th District at 96% on October 16, 2026, three days after Vancil said Sorensen declined a Peoria forum, which means the dispute leaves a seat won by under four points in 2022 priced as safe.
What the Illinois People Index Holds
There are no person pages here yet. The rule that adds one is narrow: an Illinoisan joins when one of the state's contracts prices a race they are in, or names them outright, and an official source confirms the office they hold or the ballot line they are on. For a sitting officeholder that means Wikidata matched against the office's own website, the Clerk of the House member list or the U.S. Senate roster; for a candidate, the State Board of Elections' list for the November 3, 2026 general election. Until then, the people behind the races appear on the governor market page, the Senate market page and the elections page.
What Changes the Illinois People Index
Names come from ballots and offices, never from an exchange's label. Kalshi's candidate-level board for the 4th District names Chris Getty and Mayra Macias, but the State Board of Elections' list marks Macias's independent filing as removed on July 21, 2026, so a label on its own proves nothing about who is running. Dated events change a person's page once it exists: the November 3 vote, the State Board's proclamation of results by December 4, the swearing-in that follows, a resignation or an appointment. One race already moves a name between offices: Juliana Stratton, Lieutenant Governor since January 14, 2019, is the Democratic candidate for the U.S. Senate, and Christian Mitchell is the party's candidate for her current office.
Why Illinois Politician Prediction Markets
Every Illinois election contract on this site pays on a party. Kalshi settles on the party of the governor inaugurated or the member sworn in, so a person page carries the race, the office and the contract's terms rather than a price of its own. The price lives on the market page, as the cheapest Yes any exchange quotes, with the exchange named. Read that way, a price is a reading of the race and never a verdict on the person, and nothing here grades a politician or favors a party. A contract on a national question that names an Illinoisan would sit on that person's page as a linked market, not as an Illinois market page.

How do prediction markets on politicians work?
