Prices converge toward the true outcome as the game approaches, rewarding accurate predictions and penalizing incorrect ones.

This market resolves around Jul 5, 2026, once the Philadelphia-Kansas City game concludes and the final outs total is verifiable from credible public sources. The outcome is determined by counting the total outs recorded by both teams combined during the game. Traders holding the correct side of the contract at resolution receive their payout, while those on the losing side forfeit their stake. Resolution is automatic once the official game result is confirmed.

Several factors could shift prices in this market before resolution. Lineup announcements, particularly the inclusion or absence of key batters, directly influence expected outs. Pitching matchups and bullpen depth affect how long relievers stay in the game, which impacts total outs. Weather conditions—wind speed and humidity—can alter ball carry and defensive positioning. Injury reports or late roster changes create uncertainty. As game time nears, historical outs data from similar matchups may influence trader positioning. During the game itself, early inning performance will signal whether the actual pace is tracking above or below the market threshold.
