Milwaukee Brewers win the 2026 World Series priced at 91.4% on Polymarket, down 5.5 points, on $2.9M traded

Brewers contract retreats but remains above 90%

The Polymarket contract on the Milwaukee Brewers winning the 2026 World Series was priced at 91.4%, down 5.5 probability points over 24 hours, with $2.9M traded, according to the supplied market update. Despite the decline, the price continued to imply a high likelihood of a Brewers championship.

According to PredictionBubbles, its movers board placed the contract among declining sports markets in the Oct. 28, 04:44 UTC snapshot cited in the summary. The supplied page carries a later venue-data timestamp of 28 Oct 2026, 05:14 UTC, but does not reproduce the Brewers contract’s individual figures.

What the board measures

PredictionBubbles tracks prices from Polymarket and Kalshi and updates its rankings every 15 minutes. Markets are ordered by the size of their 24-hour probability-point changes, rather than relative percentage changes; trading volume and liquidity provide context without affecting rank.

The supplied board covers 2,027 markets lasting longer than 14 days. Only open contracts with a valid 24-hour comparison qualify, while same-week fixtures are excluded to prevent moves associated with imminent settlement from dominating the rankings.

The material does not identify a game result, announcement or other catalyst behind the Brewers decline. It also does not specify the measurement period for the reported $2.9M traded, so that figure should not be treated as confirmed 24-hour turnover.

What it means for prediction markets

• A retreat, not a reversal: The 5.5-point decline reduced the contract’s implied probability, but its 91.4% price still reflected a strongly favored outcome.
• Volume is not liquidity: The reported $2.9M provides trading context, but the supplied material does not establish order-book depth or how much trading accompanied the decline.
• The cause remains unverified: The board documents repricing, not why it happened. Neither the move nor its ranking independently establishes a change in the Brewers’ underlying championship prospects.
