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 1 h ago. Ages are as of when this page was built.

Live prediction market odds for "UEFA Nations League 2027 Finals Host". Spain leads at 40.2%. Next is France at 23.6%. $136K has traded across 17 outcomes on Kalshi and Polymarket. The market is expected to resolve by Jun 10, 2027.
This market will resolve according to the country officially announced by UEFA as the host of the 2027 UEFA Nations League Finals, currently scheduled for June 9-13, 2027. A qualifying announcement means an official confirmation by UEFA of the country selected to host the Finals. Bid proposals, recommendations by member associations, and media speculation about UEFA's decision will not qualify on their own. Under UEFA regulations, the host is selected by the UEFA Executive Committee, preferably from among the four teams that qualify for the Finals. A qualifying announcement before this market's close date will immediately resolve this market to the corresponding option, regardless of any subsequent change to the host or to the scheduled dates of the Finals. If no host is officially announced by June 9, 2027, 11:59 PM ET, this market will resolve to "Other". The primary resolution source for this market will be official information from UEFA.
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.
