Resolution criteria on PolyGram: 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”.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

The 2026 Major League Baseball season will culminate in October with the American League Championship Series, determining which team advances to the World Series. The current order book on Polymarket implies a 5% probability for this market resolving YES, reflecting the distributed likelihood across the 15 AL teams competing for the pennant. This compressed probability reflects the inherent uncertainty in a season still months away, where roster composition, injury patterns, and mid-season trades remain unresolved variables.
Historical context suggests that preseason probabilities for individual league champions typically range between 5% and 15% for competitive franchises, with the strongest rosters occasionally reaching 20%. The AL has produced relatively balanced competition in recent years, with no single team dominating the regular season consistently enough to command outsized championship odds. Teams like the Houston Astros and New York Yankees have periodically held stronger positions, though postseason performance frequently diverges from regular-season strength due to playoff volatility and matchup dynamics.
Traders should monitor several catalysts through 2026: major free-agent signings and trades during the off-season, spring training performance indicators, and injury reports for key players. The trade deadline in late July typically reshapes contending rosters, whilst the AL East and AL West divisional races will clarify which teams maintain playoff positioning. Recent reporting from MLB.com and ESPN will provide updates on roster moves and team trajectories as the season progresses. The settlement window closes on 1 November 2026, allowing resolution shortly after the ALCS concludes in early October.
