Polymarket defines three mutually exclusive binary markets (El Ahly win, Draw, Smouha win) where exactly one resolves YES, while Kalshi defines three independent YES/NO markets that can all resolve YES simultaneously if the match completes normally. This creates a logical contradiction: under Polymarket logic, only one outcome is possible; under Kalshi logic, all three outcomes trigger YES in their respective markets.
Hero Tip:
Do not assume Polymarket and Kalshi markets are interchangeable. On Polymarket, betting YES on El Ahly win means betting NO on Draw and Smouha win (mutually exclusive). On Kalshi, all three markets resolve YES if the match occurs and completes—they are not mutually exclusive. Arbitrage or hedging strategies that work on one platform will fail on the other.
Critical Divergence Points:
Polymarket:
Outlier: Polymarket structures the event as three mutually exclusive binary markets where exactly one resolves YES based on the final 90-minute result. The Draw market uniquely resolves YES if the game is canceled with no make-up, creating an asymmetric cancellation rule. Key quote: 'If the game is canceled entirely, with no make-up game, this market will resolve "Yes"' (Draw only); El Ahly and Smouha markets resolve NO on cancellation.
Kalshi:
Outlier: Kalshi defines three independent outcome-based markets (Al Ahly wins, Smouha wins, Tie) that each resolve YES if their respective outcome occurs after 90 minutes plus stoppage time. All three markets can resolve YES simultaneously if the match completes normally. Key quote: 'If Al Ahly (EGY) wins... then the market resolves to Yes. If Smouha wins... then the market resolves to Yes. If Tie wins... then the market resolves to Yes.'
