How many games will the 2026 World Series last? It is best-of-seven, so it ends when one team wins its fourth game. The League Championship Series are being played now: Dodgers vs Brewers in the NL, Guardians vs Rays in the AL. World Series Game 1 is scheduled for Friday, October 23, 2026. Game 7, if needed, is scheduled for Saturday, October 31. Resolution: the answer equal to the total number of World Series games played to a decision (4, 5, 6 or 7), per the final series result on MLB.com. Suspended games that are later completed count once. Rainouts and postponements do not count as games. If the series is not completed by December 31, 2026, or MLB shortens or cancels it, this resolves N/A. The market stays open during the series. I will resolve it within 24 hours of the final out. I will not trade this market for at least 7 days after creating it, per my own operating rules.
