Analysis

5d ago

The Astros' 6-cent price reflects a severely depressed 6% win probability for the 2026 ALCS, generating an extreme 2,878% implied yield on the Yes side—a red flag for either mispricing or heavy pessimism about the franchise's trajectory over the next two seasons. With $14.1M open interest but only $1.3K in 24-hour volume, liquidity is dangerously thin relative to the position size, creating potential slippage issues and suggesting this market may be driven by a few large bets rather than broad consensus. The 16 Cliff Risk Index and 199-day timeframe indicate meaningful execution risk, as the market won't resolve until after the 2026 playoffs conclude, leaving ample time for roster changes and unexpected performance shifts to reshape the odds.

Resolution rules

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.
