Context

This market tracks which team will win the 2026 American League Championship Series. It resolves to 'Yes' for the team that clinches the pennant, or to 'No' for any listed side that gets eliminated from contention. If the ALCS is canceled or not completed by the cutoff, all options resolve to 'Other'. The market's deadline is Nov 1, 2026. As it stands, the Yankees are the most favored outcome at 26.5%, but the market’s assessment is that their candidacy is a substantial minority view — meaningful, yet far from a consensus lock. That leaves considerable room for alternatives. Seattle at 17.0% and Tampa Bay at 15.5% are each seen as having a slim but non-trivial path. The other nine teams register only negligible interest, collectively representing a tail risk. Trading activity has been modest, with total volume around $4.1M. The price has ranged between 26.5% and 34.5% during the life of the contract.

FAQ

What determines the outcome of this market?

The market resolves based on which team wins the 2026 American League Championship Series. If a team is eliminated in the postseason, its contract resolves to 'No'. If the ALCS is cancelled or postponed beyond the resolution deadline, all contracts resolve to 'Other'. Official sources from Major League Baseball or credible reporting are used for settlement.

Why are some teams listed with probabilities and others not?

Only three teams have a large enough probability to be discussed individually: the Yankees, Mariners, and Rays. All other AL teams have contracts too, but their chances are small enough that they're grouped as long shots. This reflects the market's collective judgment about which clubs are genuine contenders.

What does the current probability for the Yankees mean?

At 26.5%, the Yankees are considered a substantial minority candidate — they're the top pick, but not dominant. The probability indicates that the market sees a meaningful chance they win, but there's still plenty of uncertainty about the final outcome.

How quickly do these probabilities change?

Prices can move with every major development, from player injuries to winning streaks. Even small changes often reflect new information being absorbed by traders.

What happens if the event doesn't take place?

If the 2026 ALCS is cancelled or there is no winner declared by the cutoff date, all contracts resolve to 'Other'. This prevents funds from being locked up indefinitely and provides a clear endpoint for the market.
