The 2026 MLB Playoffs American League Division Series between the Cleveland Guardians and Chicago White Sox is a best-of-five series, won by the first team to win three games. Each market in this event names a team and a series spread of -1.5 or -2.5 games, and its two outcomes are the named team with that spread (for example, "Guardians -1.5") and the other team with the opposite spread (for example, "White Sox +1.5"). A -1.5 spread is covered if the named team wins the series 3-0 or 3-1, and a -2.5 spread is covered if the named team wins the series 3-0. If the series is completed, each market will resolve to the named team's outcome if its spread is covered and to the other team's outcome if it is not. If the series is not completed by October 24, 2026, 11:59 PM ET, for any reason, including cancellation of the 2026 MLB Playoffs, a market will resolve to the other team's outcome if the other team has already won enough games that the named team can no longer cover the spread (2 games against a -1.5 spread, 1 game against a -2.5 spread). Otherwise, it will resolve to 50-50. Only games completed by that time will be counted. The resolution source for this market will be official information from MLB; however, a consensus of credible reporting may also be used.

On Polymarket, this market is priced through a continuous auction mechanism. Traders deposit collateral and buy or sell shares representing their belief about the outcome of the Guardians vs. White Sox series. As more shares are traded, the price adjusts to reflect the collective sentiment. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of a share represents the probability of that outcome occurring, and traders aim to profit by correctly predicting the result. The market’s price movements are driven by supply and demand, influenced by news, analysis, and overall market perception.
This market resolves around Oct 12, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution will be based on the official result of the MLB playoff series between the Guardians and the White Sox. The team that wins the series will determine the winning outcome in this market. It’s important to note that the official MLB results are the final authority for determining the resolution of this market, ensuring a transparent and verifiable process.
Several factors could significantly influence this market before it resolves. Any news regarding key player injuries to either the Guardians or the White Sox would likely cause a shift in the odds. Unexpected pitching changes or strong performances in preceding games could also impact trader sentiment. Furthermore, weather forecasts predicting disruptions to the series schedule, or any significant updates to team strategies, could all contribute to movement in this market. Public perception and analysis from sports commentators could also play a role.
