Two additional baseball teams play each other, and spectators gauge whether their combined runs will go over various benchmarks. The result is solely based on the actual game score without any external influences.
The market resolves to Yes if the total runs scored by both Hiroshima Toyo Carp and Yokohama DeNA BayStars in their NPB game on Sep 28, 2026, exceed specified thresholds of 5.5, 7.5, 9.5, or 11.5 runs. Each threshold defines a unique market outcome, with higher thresholds reflecting greater scoring requirements. The game must take place as scheduled; any delay or cancellation nullifies all markets. Kalshi states it is not affiliated with the Governing League, and all trademarks remain the property of their respective owners.
Prediction market odds often reflect the collective wisdom of a diverse group of traders, potentially offering a different perspective than traditional sportsbooks. Sportsbook odds are typically set by professional oddsmakers, while this market’s pricing is determined by supply and demand from individuals trading contracts. While sportsbooks consider factors like team statistics and player injuries, the prediction market can incorporate a broader range of information, including less quantifiable factors or late-breaking news. It’s common to see differences in implied probabilities between this market and sportsbook offerings, especially as new information emerges.
On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing their belief about whether the total runs scored will be over or under 5.5. The price of a contract ranges from 0 to 100, representing the probability of that outcome occurring. As more people buy contracts predicting 'over,' the price increases, and vice versa. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market dynamically adjusts as traders react to new information and refine their predictions, creating a real-time assessment of the likely total runs in the game.
This market resolves around Sep 28, 2026, with the outcome confirmed once the final score of the Hiroshima Toyo Carp versus Yokohama DeNA BayStars game is verifiable from credible public reporting. The total number of runs scored by both teams will be used to determine whether the 'over' or 'under' contract wins. The resolution will be based on official game statistics, ensuring a transparent and accurate determination of the result. Traders holding contracts on the winning side will receive a payout of 100 minus the contract price they paid.
Several factors could influence the price of this market. Any news regarding key player injuries or starting pitcher changes for either the Carp or the BayStars would likely cause significant movement. Weather conditions at the game location, particularly forecasts for rain or wind, could also impact scoring expectations. Late-breaking reports on team strategies or lineup adjustments could also play a role. Furthermore, significant shifts in public sentiment, perhaps driven by pre-game analysis or social media discussions, could influence trading activity and move the market price.
