Kalshi's three markets collectively cover all possible outcomes (Adelaide win, Auckland win, or draw) and each resolves YES for its respective outcome, creating logical contradiction where exactly one must resolve YES regardless of result. Polymarket's three markets are mutually exclusive binary outcomes (Adelaide YES/NO, Draw YES/NO, Auckland YES/NO) that align with standard sports betting logic. The platforms use fundamentally incompatible resolution structures.
Hero Tip:
Do not cross-hedge between Kalshi and Polymarket on this event. Kalshi's structure guarantees one market resolves YES (creating synthetic long exposure), while Polymarket's structure allows all three to resolve NO (if game is canceled). If betting on Kalshi, you are implicitly long the event occurring; on Polymarket, you can be short all outcomes. Verify game status before settlement.
Critical Divergence Points:
Kalshi: Outlier: Uses three markets that each resolve YES for a single mutually-exclusive outcome (Adelaide win, Auckland win, or draw), guaranteeing exactly one YES resolution if the match completes. Key quote: 'If Adelaide wins... then the market resolves to Yes. If Auckland wins... then the market resolves to Yes. If Tie wins... then the market resolves to Yes.'
Polymarket: Outlier: Uses three independent binary markets (Adelaide YES/NO, Draw YES/NO, Auckland YES/NO) where all three can resolve NO if the game is canceled with no make-up. Key quote: 'If the game is canceled entirely, with no make-up game, this market will resolve No' (for Adelaide and Auckland) and 'this market will resolve to Yes' (for Draw). This creates asymmetric cancellation logic across the three markets.
