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. Ages are as of when this page was built.

Live prediction market odds for "AP calls the House by...?". December 31, 11:59 PM leads at 99.1%. Next is November 10, 11:59 PM at 97.6%. $15K has traded across 12 outcomes on Polymarket. The market is expected to resolve by Nov 4, 2026.
This market will resolve to “Yes” if the Associated Press has, by the specified date and time (ET), called control of the United States House of Representatives for the Congress that will convene following the midterm elections. Otherwise it will resolve to “No”. Control of the House of Representatives will be considered to have been called when the Associated Press has either 1) issued a call that House control has been determined, or 2) issued race calls declaring winners in at least 218 districts for candidates of the same party, with all such calls standing at the same time for 1 hour without retraction. Independents will not be considered members of a party for purposes of this count. Under condition 1, no subsequent withdrawal of a control call will be relevant to this market. Under condition 2, this market will remain open for one hour following the race call that brings a party’s standing calls to 218. If, within that hour, the Associated Press retracts any of those calls such that the party’s standing calls fall below 218, condition 2 will not be considered satisfied by that call. If no such retraction occurs within the hour, condition 2 will be considered satisfied as of the time of the 218th call, regardless of any later retraction. For resolution, the relevant time is the time of the 218th call, not the end of the one-hour period. The resolution source for this market will be the Associated Press.
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.
