The primary resolution source for this market is the official final statistics of the event as recognized by the governing body or event organizers. However, if the governing body or event organizers have not published final match statistics within 24 hours after the event's conclusion, a consensus of credible reporting may be used instead.
Resolution depends on the run differential at the end of the fifth inning of the Miami vs Philadelphia game originally scheduled for June 16, 2026 at 6:40 PM EDT. Markets are offered for Philadelphia winning by more than 1.5 or 2.5 runs, and for Miami winning by more than 1.5 or 2.5 runs. Each outcome resolves to Yes if the specified team wins by more than the stated margin through five innings. If the game is postponed or delayed, the market remains open and closes after the rescheduled game concludes within two days.
Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform attracts distinct trader demographics, liquidity pools, and fee structures. Polymarket may draw more casual volume on directional bets, while Kalshi appeals to traders seeking precise margin-based outcomes. Differences in market depth, settlement speed, and promotional incentives can also widen spreads. Arbitrage opportunities between the two venues reward alert traders who spot and exploit these gaps before prices converge.
Key catalysts include starting pitcher announcements, last-minute lineup changes, and weather updates affecting ball carry and visibility. Injury reports on star hitters or relief arms can shift early-inning dynamics significantly. Pregame betting action at sportsbooks often telegraphs sharp money flow, influencing prediction market prices. Live game action—early runs, errors, or momentum swings in the first few innings—will drive real-time repricing as traders react to unfolding play.
