The Washington vs Boston game scheduled for July 1, 2026 at 1:35 PM EDT will be evaluated for total combined runs scored by both teams. Resolution occurs when the final game score is determined, with separate binary outcomes for whether the combined total exceeds 4.5, 5.5, 6.5, 7.5, 8.5, 9.5, 10.5, 11.5, 12.5, 13.5, or 14.5 runs. Each threshold represents an independent market outcome based on the official final score of the game.
Prediction market odds and sportsbook odds often diverge because they reflect different participant bases and incentive structures. Sportsbooks set lines to balance action and manage risk, while prediction markets aggregate trader beliefs through continuous price discovery. This market may show higher or lower implied probabilities than traditional sportsbooks, depending on whether informed traders see value the books have missed. Comparing the two can reveal where sharp money is positioning ahead of the game.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares representing yes or no outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each share reflects the collective expectation of the total runs scored by both teams. As new information emerges—lineup announcements, weather updates, or injury reports—traders adjust their bids and offers, moving the market price to reflect changing probabilities in real time.
This market resolves around Jul 1, 2026, once the Washington vs Boston game concludes and the final run total is verified. The outcome is determined by the official combined runs scored across both teams during the complete game.
