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 19.5% and Seattle Mariners at 16.5% to win the 2026 AL pennant, reflecting early-season parity across a deep American League where no team has separated after about 17 games. The Yankees sit at 9-8, nipping at the Rays' heels in a loaded AL East alongside the Orioles, bolstered by positive rehab updates for Gerrit Cole and Carlos Rodón that could deepen their rotation soon. Mariners hover at 9-9 in a tight AL West led by the Rangers, hampered by catcher Cal Raleigh's slow start despite elite pitching. Detroit Tigers at 8-9 lag in the Central behind surging Twins and Guardians but retain upside from their young core and preseason projections, underscoring the wide-open wild card and division paths keeping the race competitive.
