The board as of 5 October
Eight teams remain. The Los Angeles Dodgers, back-to-back champions, are the favourite at around +240 (bet365, checked 5 October 2026) to become the first team since the 1998–2000 Yankees to win three straight World Series.
Behind them: the Milwaukee Brewers at +300 (BetMGM), the Tampa Bay Rays at +575 (BetMGM), the New York Yankees at +750 (bet365), the Atlanta Braves at +800 (BetMGM), the Chicago White Sox at +1000 (bet365), the Cleveland Guardians at +1700 (BetMGM) and the San Diego Padres at +4000 (bet365).
Those are best available prices across the books quoting that day. Your book's number will differ, and it will move.
Why Milwaukee is the story
The Brewers finished 103–59, the best record in baseball, winning the NL Central by 14 games. They have played in one World Series — 1982, a seven-game loss to St. Louis — and have never won one.
At +300, the market gives them roughly a one-in-four implied chance. That is the price of a very good team standing in the way of a dynasty, not the price of a favourite.
The White Sox went from +50000 to +1000
No preseason board respected Chicago. The White Sox opened around +50000 at some books — a lottery ticket, not a prediction — and played their way into the final eight at +1000.
This is the part of October where the board stops being about the 162-game season and starts being about who is healthy and hot right now.
What +240 actually means
American odds of +240 imply about a 29% chance, before the book's margin. The Dodgers are the most likely single winner and still lose this tournament more than two times in three, on the market's own math.
Futures boards are entertainment pricing with a margin built in. They are not forecasts, and the eight-team field means seven fan bases go home unhappy.
