Milwaukee’s contract to win the 2026 Pro Baseball Championship was priced at an implied probability of 83.5% on Kalshi, down 0.8 percentage points, with $13.0M traded, in the Oct 26, 2026 · 9:54 AM ET snapshot. According to PredictionBubbles, the contract sits among the most-traded markets on its sports board.
A high probability, with a modest decline
The price indicates traders still strongly favor a Milwaukee championship, despite the decline. PredictionBubbles defines its probability-change column as the move over the previous 24 hours, measured in percentage points.
The supplied material does not identify a game result, lineup change, injury or other development behind Milwaukee’s move. The price and volume therefore establish the market’s position, but not the reason for its repricing.
Volume rankings and refresh limits
According to PredictionBubbles, its sports category covers 539 open markets across Kalshi and Polymarket: 190 from Kalshi and 349 from Polymarket. Its embedded display features the 300 largest markets by traded volume, while the full board covers the broader set. Volume rankings are separate from rankings based on absolute probability changes over the last 24 hours.
Milwaukee was not the board’s volume leader. At the last refresh, PredictionBubbles identified the Polymarket contract on whether Shakhtar Donetsk would win the 2026-27 UEFA Champions League Championship as the most traded sports market, with $35.8M in volume.

What it means for prediction markets
Probability is not certainty: Milwaukee’s 83.5% price represents traders’ implied assessment, not a confirmed championship outcome.
Volume and direction are different signals: The $13.0M figure measures total trading, while the 0.8-point decline describes the probability change over 24 hours.
Timing matters: A board snapshot can lag subsequent trades because the data refreshes every 15 minutes.
Cross-venue comparisons require care: PredictionBubbles notes that related Kalshi and Polymarket contracts can have different wording and resolution rules.
