The Milwaukee Brewers enter the 2026 World Series as the clear market favorite after posting MLB's best regular-season record at 103-59 and sweeping the two-time defending champion Dodgers in the NLCS. Their pitching staff led the league in ERA while the lineup posted the top mark in runs scored, supporting the 64% implied probability reflected in current pricing. The Tampa Bay Rays, who finished 98-64 and claimed the AL pennant, sit at 36% despite strong home performance and a deep playoff run that eliminated the Yankees and Guardians. Game 1 at American Family Field features Milwaukee starter Jacob Misiorowski against Tampa Bay's Nick Martinez, with both clubs seeking their first franchise title in a best-of-seven matchup that begins October 23.
