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 on the 2026 American League pennant reflects preseason parity, with Seattle Mariners (17%) edging New York Yankees (16%) amid stacked divisions and key offseason bolstering. Mariners lead power rankings thanks to elite rotation depth and prospect influx, positioning them for AL West dominance despite modest batting average gains needed. Yankees fortified their lineup via Cody Bellinger's five-year pact and Gerrit Cole's post-Tommy John return, challenging in a brutal AL East alongside Toronto Blue Jays (12%), whose core talent persists despite opening-day rotation injuries to Shane Bieber and Jose Berrios. Detroit Tigers (10%) surge on AL Central favoritism and young roster momentum, underscoring wide-open wild card paths and no clear playoff locks as Opening Day unfolds.
