MLB World Series Champion 2026

About this market

Who prices it. $45.5M has changed hands on Polymarket since it opened, $186K of it in the past day, with $258K in resting orders. The gap between the best buy and sell price on Milwaukee Brewers is 1.7 points, so the quoted price is a fair read.

Other venues. Polymarket is the only venue we track that lists this exact question, so there's no second price to check it against.

What has moved it. No outcome has moved past our alert threshold in the past week. The latest headline we matched to it is “ALCS Game 6: Takeaways as Rays advance to World Series” (ESPN, October 20, 2026).

What would change it. The fixed date is the deadline: it settles by October 31, 2026, 12 days away. Before then the price should mainly move on news that touches the rules below.

How it settles, in short. This market will resolve according to the team that wins the 2026 MLB World Series. If at any point it becomes impossible for a listed team to win the 2026 MLB World Series per the rules of MLB (e.g., they are eliminated in the playoffs), the corresponding market will resolve to “No”.
