Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. 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 37 min ago. Ages are as of when this page was built.

Indicative gap, prices are 37 min old: Kimi Antonelli asks 25¢ on Kalshi and bids 26¢ on Polymarket (100 bps). Recheck both venues before trading. See all spreads

Mostly the same bet: 6 differences

Where they differ

  • Kalshi: if race is cancelled, moved to a different circuit, or not started within 48 hours of scheduled start, all markets resolve to a fair price. Polymarket: cancelled or rescheduled after Nov 15, 2026 resolves to 'Other'; a delay of up to 7 days still counts. Postponement of 2-7 days is handled differently.
  • Polymarket lists Esteban Ocon and Yuki Tsunoda, which Kalshi does not list; Kalshi lists Ryo Hirakawa, which Polymarket does not list. Unpaired outcomes are not linked.
  • Polymarket says disqualifications or changes after publication of the Final Classification do not affect resolution; Kalshi pays after the Final Classification is posted but does not say how later changes are handled.
  • Polymarket also names the official F1 website and credible reporting as resolution sources, while Kalshi names only the FIA Final Classification; both rely on the FIA classification in practice.
  • Polymarket rules say 'Kimi Antonelli' while Kalshi uses 'Andrea Kimi Antonelli'; same driver.
  • Trading closes at different times: Nov 15, 2026, 5:00 PM UTC on Polymarket and Nov 15, 2026, 11:00 PM UTC on Kalshi.

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.
