This market will resolve according to the team that wins the 2026 American League Championship Series. If at any point it becomes impossible for a listed team to win the 2026 American League Championship Series per the rules of the MLB (e.g., they are eliminated in the playoffs), the corresponding market will resolve to “No”. If the 2026 American League Championship Series is cancelled, postponed after November 31, 2026, 11:59 PM 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 Major League Baseball (https://www.mlb.com/); however, a consensus of credible reporting may also be used.Trader consensus gives the Seattle Mariners an 18% implied probability as 2026 American League champions, narrowly ahead of the New York Yankees (16.5%) and Toronto Blue Jays (13%), underscoring the AL's wide-open parity with five teams above 10% and no probability exceeding 20%. This tight clustering stems from balanced offseason roster enhancements and young talent across divisions: Mariners bolstered their elite rotation (Castillo, Kirby, Woo) and outfield depth after a strong 2024 finish; Yankees rely on Judge, Cole, and Volpe despite Soto's Mets signing; Blue Jays feature Guerrero Jr., Bichette, and potential pitching adds; Red Sox gained ace Crochet via trade; and Tigers ride Skubal's Cy Young momentum plus emerging hitters like Riley Greene. AL East depth, Central resurgence, and West volatility keep the race competitive.
