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 5 min ago. Ages are as of when this page was built.

Live prediction market odds for "United States Grand Prix: Driver Pole Position". Max Verstappen leads at 33.4%. Next is Kimi Antonelli at 24.5%. $140K has traded across 24 outcomes on Kalshi and Polymarket. The market is expected to resolve by Oct 31, 2026.
This is a polymarket on the driver who achieves pole position at the 2026 F1 United States Grand Prix, scheduled for Oct 24, 2026. If the 2026 F1 United States Grand Prix is canceled or rescheduled to a date after Oct 31, 2026, this market will resolve to “Other.” This market will resolve in favor of the driver who is officially recognized by Formula 1 as having set the fastest time during the qualifying session for the 2026 F1 United States Grand Prix. The market will be settled based on the FIA's official qualifying results, regardless of any subsequent penalties, disqualifications, or changes to the starting grid. For example, if a driver sets the fastest qualifying time but later receives a grid penalty or is moved down the starting order, the market will still resolve to “Yes” for that driver. The resolution source will be the official Formula 1 website and a consensus of credible sports news reporting.
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.
