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 prices the New York Yankees at 28.5% implied probability to claim the 2026 AL pennant, driven by their strong 27-16 start—just two games behind division-leading Tampa Bay Rays (28-13)—bolstered by elite offensive depth and the anticipated returns of aces Gerrit Cole and Carlos Rodón from the injured list. Seattle Mariners rank second at 15.5% on their vaunted rotation's dominance despite a middling 21-22 record, positioning them as wild card threats amid a tight AL West led unexpectedly by the Athletics. Rays sit third at 10.6% as traders question their lineup sustainability behind the hot pitching; Texas Rangers (7.5%) and surging Detroit Tigers (6.5%) round out leaders via veteran core and youthful breakout in the weak AL Central, underscoring a wide-open race with ample wild card paths.
