Kimi Antonelli 66%
Next is Max Verstappen at 51.1%. Polymarket and Kalshi agree within 1 point on each matched outcome.
Consensus blends each venue’s last price, weighted by how much has traded there. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.
Prices come from our regular polls of each venue, the oldest 2 min ago. Ages are as of when this page was built.

Live prediction market odds for "United States Grand Prix: Driver Podium Finish". Kimi Antonelli leads at 66%. Next is Max Verstappen at 51.1%. $164K has traded across 24 outcomes on Kalshi and Polymarket. The market is expected to resolve by Nov 1, 2026.
This market will resolve to “Yes” if the listed driver finishes within the top three positions in the official "Final Classification" for the F1 United States Grand Prix, scheduled for Oct 25, 2026. Otherwise, this market will resolve to “No.” The "Final Classification" is published by the FIA following the conclusion of the race and includes any applied time penalties and official adjustments. It is typically released 30-60 minutes after the race ends. Disqualifications or changes made after the publication of the "Final Classification" will not affect market resolution. The timing of the podium ceremony does not determine the result for this market — only the FIA's published classification will be used to resolve this market. If the United States Grand Prix is postponed, this market will remain open until the event has been completed. If the United States Grand Prix is permanently canceled, this market will resolve 50-50.
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%.
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.
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.
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.
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.
