About this market

Final prediction market prices for "Illinois Governor Republican Primary Winner". Gregg Moore last traded at 0.1%. Next is Rick Heidner at 0.1%. $82K has traded across 3 outcomes on Polymarket. The market closed on Mar 17, 2026.

This market will resolve according to the winner of the Republican Primary for Governor of Illinois, scheduled to take place on March 17, 2026. Resolution will be based on the overall winner of the primary, including any potential second round or run-off. If no 2026 Illinois Gubernatorial Republican Primary takes place, this market will resolve to “Other.” The resolution source for this market will be the first official announcement of the results from the Illinois Republican Party; however, an overwhelming consensus of credible reporting may suffice.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
