This event covers over/under betting on the combined runs scored by the Yankees and Red Sox during only the first five innings of their game on June 25, 2026. Bettors can wager on whether the combined first-five-inning total will exceed thresholds ranging from 0.5 to 6.5 runs.
Resolution is determined by the combined run total scored by both teams during the first five complete innings of the game originally scheduled for June 25, 2026 at 7:10 PM EDT. Each primary rule establishes a specific run threshold; if the combined first-five-inning total exceeds that threshold, the corresponding market resolves to Yes. If the game is postponed or delayed, the market remains open and closes after the rescheduled game has finished, within two days of the original scheduled date.
Prediction market odds and sportsbook odds often diverge because they serve different purposes and audiences. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets like this one aggregate trader beliefs through continuous price discovery. Traders here may price the first-inning run total differently than a sportsbook, reflecting real-time consensus rather than a fixed opening line. Comparing the two can reveal where smart money sees value or where public perception differs from market-maker positioning.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares representing different run-total outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each share reflects the probability traders assign to that outcome, and the price updates continuously as new orders match. You can place limit or market orders to enter or exit your position, and the spread between bid and ask prices shows the current liquidity and conviction around each outcome.
This market resolves around Jun 26, 2026, once the New York versus Boston game concludes and the first five innings are complete. The outcome is determined by the official combined run total recorded through the end of the fifth inning, verified against credible public sources. Once the result is confirmed and finalized, your position settles based on whether your prediction matched the actual total.
Several factors can shift prices before resolution. Lineup announcements, starting pitcher confirmations, and recent team form or injury updates often trigger significant moves. Weather conditions on game day—wind speed and temperature affect ball carry—can influence early-inning scoring expectations. Pregame betting action at sportsbooks and sharp-money positioning may also signal where informed traders expect the first five innings to land. Real-time game developments, such as early runs or pitching changes, will drive the most dramatic repricing as the contest unfolds.
