After entering the 2026 Major League Baseball season with respectable 16-1 odds to win the World Series, the Boston Red Sox looked hapless through the first half of the season, plunging into the 100-1 range for championship futures. Then, Boston put together nine straight wins heading into the All-Star break and has now extended that out to 13 games -- the team's longest winning streak since 1948 -- giving the Red Sox 25-1 World Series odds, 10th best on the board.
The Chicago White Sox have also continued their incredible turnaround this season and are down to 40-1 to win the World Series. The South Siders are now -135 to make the playoffs and +160 to win the AL Central. They are a big futures liability at multiple sportsbooks.
The top of the World Series odds board remained the same coming out of the MLB All-Star break, with the Los Angeles Dodgers (+190) and New York Yankees (+550) continuing to lead the way. The Milwaukee Brewers continue to improve in the contender conversation, shortening to 10-1 from 35-1 at the beginning of the season and from 11-1 week-over-week. The Atlanta Braves stand alone at 12-1 after sharing that number with the Seattle Mariners (13-1) and Philadelphia Phillies (13-1) just one week ago.
