Polymarket and Kalshi use fundamentally incompatible market structures for the same event. Polymarket offers three mutually exclusive binary markets (Gwangju win, Bucheon win, draw), while Kalshi offers three separate YES/NO markets that can theoretically all resolve YES simultaneously, creating a logical contradiction.
Hero Tip:
Do not assume Polymarket and Kalshi outcomes will mirror each other. On Polymarket, exactly one of the three markets will resolve YES. On Kalshi, all three markets could resolve YES if the platform interprets each as independent outcome confirmations rather than mutually exclusive results. Verify the platform's settlement procedure before placing cross-platform hedges.
Critical Divergence Points:
Polymarket: Distinct stance: Polymarket structures the event as three mutually exclusive binary markets where exactly one outcome (Gwangju win, Bucheon win, or draw) will resolve YES and the other two will resolve NO. The resolution source is official K League statistics or credible reporting consensus within 2 hours of match conclusion. Quote: 'If Gwangju FC wins, this market will resolve to Yes. Otherwise, this market will resolve to No' (applied identically to all three outcome markets).
Kalshi: Distinct stance: Kalshi presents three separate YES/NO markets, each confirming whether a specific outcome occurred (Gwangju win, Bucheon win, or tie). The market structure does not explicitly state mutual exclusivity, creating ambiguity about whether all three could resolve YES simultaneously or whether only one should. Quote: 'If Gwangju wins...then the market resolves to Yes. If Bucheon wins...then the market resolves to Yes. If Tie wins...then the market resolves to Yes.'
