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.The Los Angeles Dodgers command a 28.5% implied probability as 2026 World Series favorites, bolstered by their 2024 championship core and recent offseason additions like Blake Snell's five-year, $182 million deal, enhancing a rotation featuring Shohei Ohtani's pitching return, Yoshinobu Yamamoto, and Tyler Glasnow amid pursuit of Roki Sasaki. Seattle Mariners (8.6%) stand out with MLB's deepest starting rotation—led by Luis Castillo, Logan Gilbert, and George Kirby—plus emerging hitters like Julio Rodríguez, positioning them for sustained AL contention despite modest offense. New York Yankees (7.5%) gained rotation stability via Max Fried's signing but face lineup questions post-Juan Soto's departure, while Toronto Blue Jays (6.5%) and New York Mets (6.3%) leverage Vladimir Guerrero Jr. and Soto's megadeal, respectively, in a parity-driven field with farm systems and trade deadline potential key differentiators.
