As an exclamation point on their pennant run, the Brewers swept the two-time defending champions, the Los Angeles Dodgers, in the National League Championship Series.

Polymarket traders view Milwaukee as the clear favorite in the 2026 World Series.This edition of the Brewers is the most dominant in franchise history and appears on a course to claim its first Commissioner’s Trophy. There are many similarities between these admirable teams that vanquished giants to reach the Fall Classic. Both the Brewers and Rays feature top-level starting pitchers, strive to manufacture runs instead of waiting for the big home run, and demand a high standard of defensive performance. The difference could come down to Milwaukee’s offense or Tampa Bay’s starting pitching. Neither team relied heavily on the long ball during the regular season, but the Brewers turned on the power in the NL playoffs, leading all teams with 10 postseason home runs. Milwaukee starting pitcher Jacob Misiorowski is regarded as the best hurler on either side but was less effective in two NL playoff starts, getting chased before he finished five innings. Meanwhile, the Rays’ anchor SPs, Drew Rasmussen and Freddy Peralta, allowed five earned runs in 37.2 innings of work in the AL playoffs.

Three of the top four and four of the top six MVP candidates are from Milwaukee. Chourio and Contreras have elevated the Brewers’ offense during the postseason. Chourio hit seven of Milwaukee’s 10 HRs during the NL playoffs. Contreras has a .367 postseason batting average and led all National Leaguers with a 1.157 OPS. Brice Turang fashioned a .382 OBP in the NL playoffs. Caminero hit .273 with one HR and four RBIs during the AL playoffs. He and Diaz have combined for eight RBIs in the postseason. The two Tampa Bay offensive centerpieces must raise their games in the World Series for Tampa Bay to pull off the upset.World Series Total GamesTotal games marketPolymarket US price5 games$0.816 games$0.607 games$0.36This is another market showing that Polymarket users think the dominant team will leave no doubt. Because the Brewers toppled the Dodgers, Polymarket users think the Rays will take out the Rays quickly.But Tampa Bay’s starting staff may be better overall, and if Milwaukee’s top pitcher doesn’t look as good as he did during the regular season, then those who trade on a seven-game series could walk away with a healthy profit.
