The 2026 World Series Opens on 23 October

Major League Baseball's published postseason schedule puts World Series Game 1 on Friday 23 October 2026, with Game 7 on Saturday 31 October if the series goes the distance. On 20 September 2026 Kalshi's champion market had no runaway favourite: the Dodgers sat at 29%, Milwaukee at 16% and the Yankees at 10%.

Game 1 of the 2026 World Series is set for Friday 23 October 2026, per the postseason schedule Major League Baseball announced and ESPN's date-by-date version of it^[2][3]
The series is best-of-seven in a 2-3-2 format, with the team holding the better 2026 record hosting Games 1–2 and, if necessary, Games 6–7^[2][3]
The full slate runs Game 1 on Friday 23 October, Game 2 Saturday 24 October, Game 3 Monday 26 October, Game 4 Tuesday 27 October, and if necessary Game 5 Wednesday 28 October, Game 6 Friday 30 October and Game 7 Saturday 31 October^[2][3]
Travel days fall on 25 and 29 October, the latter only if the series lasts more than five games^[2]
A winner-take-all Game 7 would be played on Halloween night, and ESPN notes “There is no November baseball on the calendar. Barring a rainout, Game 7 of the 2026 World Series is scheduled for Halloween night”^[2][3]
The opening date is fixed regardless of the earlier rounds: “Does the start date of the World Series depend on when the ALCS and NLCS end? No, not this year”^[2]
The World Series is presented by Capital One, with every game on FOX plus FOX Deportes and FOX One^[2]
It closes a postseason that starts unusually early, on Tuesday 29 September with the four best-of-three Wild Card Series, followed by the Division Series from 3 October, the NLCS from 11 October and the ALCS from 12 October^[2][3]
MLB published the schedule on 10 August 2026 with the caveat that “All dates are subject to change”; ESPN's version is dated 17 August 2026^[2][3]
Kalshi's champion market has no runaway favourite: Los Angeles at 29.3%, Milwaukee at 16% and New York at 9.9%, all three drifting down at capture, on $76,496,027 of volume^[1]
That Kalshi capture is of a logged-out page, so its order ticket shows no prices and reads “Odds 0% chance” with a max payout date of 31 October 2028, two years after the series it covers^[1]
