Resolution rules
This market will resolve to "Yes" if the listed team reaches the World Series of the 2027 MLB Playoffs. If at any point it becomes impossible for the listed team to advance to the World Series of the 2027 MLB Playoffs (e.g. they are mathematically eliminated), the associated market will resolve to "No". If the 2027 MLB regular season is cancelled, or no 2027 MLB regular-season game has been played by July 1, 2027, 11:59 PM ET, this market will resolve to 50-50. If the 2027 MLB Playoffs are otherwise cancelled, postponed after November 15, 2027, 11:59 PM ET, or the World Series matchup has not been declared within that timeframe, this market will resolve to "No". The resolution source for this market will be official information from MLB (https://www.mlb.com/); however, a consensus of credible reporting may also be used.

FAQ
How are prediction market odds calculated?
Each contract pays $1 if the outcome happens and $0 if it doesn't, so its price is the market's implied probability: a 60¢ contract means roughly a 60% chance. We show the last trade, or the midpoint between the best bid and ask when the order book is tight.
When does this market close?
Polymarket lists Oct 22, 2027 as the end date. It can close earlier if the outcome is decided.
