This market will resolve according to the team that wins the 2026 MLB World Series. If at any point it becomes impossible for a listed team to win the 2026 MLB World Series per the rules of MLB (e.g., they are eliminated in the playoffs), the corresponding market will resolve to “No”. If the 2026 MLB season is cancelled, postponed after December 31, 2026 ET, or there is otherwise no winner declared within that timeframe, this market will resolve to “Other”. The primary resolution source will be official information from MLB (https://www.mlb.com/); however, a consensus of credible reporting may also be used.Defending back-to-back World Series champions Los Angeles Dodgers lead trader consensus at 26.5% implied probability, bolstered by their blockbuster offseason acquisition of outfielder Kyle Tucker to join Shohei Ohtani, Mookie Betts, and Freddie Freeman in a loaded lineup, plus a deep rotation headlined by Yoshinobu Yamamoto. Seattle Mariners follow at 8.9% on elite pitching from Luis Castillo, Logan Gilbert, and George Kirby, positioning them for AL West dominance amid a wide-open field. New York Yankees and Toronto Blue Jays tie at 7.5%, with Yankees' veteran core and Blue Jays' ALCS momentum from Vladimir Guerrero Jr., while Detroit Tigers' 6.3% reflects young arms like Tarik Skubal fueling breakout potential. Preseason power rankings and spring training health underscore Dodgers' three-peat edge over contenders' roster upgrades and playoff paths.
