Odds by venue

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.

About this market

Live prediction market odds for "MLB Postseason: Longest Game". 11+ innings leads at 26.9%. Next is 12+ innings at 11%. $19K has traded across 7 outcomes on Polymarket. The market is expected to resolve by Nov 16, 2026.

This market will resolve to "Yes" if the greatest number of innings played in any single game of the 2026 MLB Postseason equals or exceeds the listed number. Otherwise, this market will resolve to "No". A game counts at the number of innings in which play occurred, as recorded by MLB in the official box score. A game that ends in the bottom of its final inning counts at that inning number, even though that inning was not completed. A suspended game that is later resumed and completed counts as a single game at its final inning total. A game that is shortened or called before completion counts at the last inning completed. Only games in 2026 MLB Postseason games will count toward this market. The 2026 MLB Postseason comprises the Wild Card Series, the Division Series, the League Championship Series, and the World Series. Regular season games, exhibition games, and any tiebreaker or "Game 163" will not be considered part of the 2026 MLB Postseason. If the 2026 MLB Postseason is cancelled, or the World Series has not concluded by November 15, 2026, 11:59 PM ET, this market will resolve to "No". The resolution source for this market will be official information from MLB; however, a consensus of credible reporting may also be used.

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.
