This event tracks the combined run total scored by both teams during only the first five innings of the June 28, 2026 game. If the game is postponed or delayed, the market remains open and resolves after the rescheduled game completes within two days.
Resolution is determined by the combined run total scored by New York Y and Boston through the completion of the fifth inning in the professional baseball game originally scheduled for June 28, 2026 at 7:20 PM EDT. Each outcome resolves to Yes if the combined total through five innings exceeds its specified threshold (0.5, 1.5, 2.5, 3.5, 4.5, 5.5, or 6.5 runs). If the game is postponed or delayed, the market remains open and closes after the rescheduled game finishes, provided it occurs within two days of the original scheduled date.
Prediction market odds and sportsbook odds often diverge because they reflect different participant pools and incentive structures. Sportsbooks set lines to balance action and protect their margin, while prediction markets like this one are driven by trader belief and real-money commitments. Sportsbooks may adjust faster for sharp action, whereas prediction markets can lag or lead depending on information flow and liquidity. Neither is inherently more accurate, but comparing the two can reveal where casual bettors and professional traders disagree on the likely first-inning run total.
On Kalshi, this market is priced through continuous order-book trading, where buyers and sellers submit bids and offers on the total runs outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price you see reflects the marginal trade—the last transaction executed—and moves as new orders arrive and old ones are filled. Higher prices indicate stronger trader conviction that the run total will exceed a given threshold, while lower prices suggest the opposite. Liquidity and trading volume influence how quickly prices respond to news or game developments.
This market resolves around Jun 29, 2026, once the game between New York Y and Boston concludes and the first five innings are complete. The outcome is determined by the combined run total scored by both teams through the end of the fifth inning, verified against credible public sources. Resolution happens automatically after the event is finalized and confirmed, at which point traders' positions settle based on whether the actual total matched their prediction.
Several factors can shift this market before the game starts and during the first five innings. Lineup announcements, weather conditions, and starting pitcher information often trigger price swings as traders reassess scoring potential. Injury news or late roster changes can alter offensive firepower. Once play begins, early runs, pitcher performance, and base-running situations will drive real-time repricing. Momentum shifts, defensive plays, and weather impacts during the game itself will continue to move odds as the five-inning window unfolds.
