Jackson Chourio’s Kalshi contract to win Pro Baseball Championship Series MVP was priced at 16.0%, down 22.0 probability points, with $757K traded, in the supplied update published Oct 28, 2026 · 11:24 PM ET.

According to PredictionBubbles’ movers-board summary, the contract was among the largest downward moves in sports. The supplied material does not identify a game result, announcement or other catalyst for the decline.

How the move is measured

PredictionBubbles ranks changes over 24 hours using probability-point differences, rather than relative percentage changes. Trading volume provides context but does not determine a contract’s position in the rankings.

According to predictionbubbles.net, the board draws prices directly from Polymarket and Kalshi and updates every 15 minutes. The supplied snapshot records venue data read on 29 Oct 2026, 03:16 UTC.

Limits of the snapshot

The board’s coverage spans 1,982 markets lasting longer than 14 days, with same-week fixtures excluded. Only open contracts with a valid 24-hour comparison qualify; resolved markets and those too new to have a comparable price are omitted.

The supplied page text explains that methodology but does not reproduce Chourio’s individual listing. The headline supplies the contract’s price, decline and traded amount, while the summary identifies its placement among downward sports movers. Neither establishes the contract’s available liquidity or explains what drove the repricing.

What it means for prediction markets

  • The decline is measured in points: the 22.0-point move represents a change in the market-implied probability, not a 22.0% relative fall.
  • Volume and liquidity are different: $757K traded provides activity context, but the supplied material does not show order-book depth.
  • The catalyst remains unverified: the snapshot documents a lower price for Chourio’s MVP outcome, not why traders changed their assessment or whether that assessment will prove correct.
