Historical Price (Probability)
Outcome probability
Date
This market has traded in a tight, four-point range between 50.0% and 54.0%, indicating a sideways trend with no strong directional conviction. The contract opened at 50.0%, pricing the game as a toss-up. It then moved higher to the 53%-54% zone, establishing that level as short-term resistance. This initial upward price movement aligns with external reports favoring the Chicago Cubs, who held a superior 61-46 record compared to the St. Louis Cardinals at 53-54. The price has since settled near 51.0%, just above the 50.0% level that has served as a floor for the market.
Trading volume was negligible until the day of the game, July 29, when it surged to over 38,000 contracts and accounted for the vast majority of the 88,885 total contracts traded. This pattern shows that market participants waited for final game-day information before committing capital. The price action, while favoring the Cubs, remains close to the 50.0% equilibrium point. This suggests that while the market acknowledges the Cubs as slight favorites based on their season performance, there is no strong consensus on the game's outcome. The slight pullback from the 54.0% peak to 51.0% indicates some buying pressure for the Cardinals contract, tightening the implied odds as the event neared.

Pitchers JoJo Romero and Dustin May, along with Lars Nootbaar, are being considered as potential trade candidates [^][^].
