Polymarket defines three mutually exclusive binary markets (Eibar win, Draw, Las Palmas win) where exactly one resolves YES, while Kalshi defines three independent markets that all resolve YES simultaneously if their respective outcomes occur, creating a logical contradiction where all three Kalshi markets would resolve YES for any match result.
Hero Tip:
Do not trade across both platforms assuming equivalent payoffs. On Polymarket, exactly one of the three markets will resolve YES (standard 1X2 betting). On Kalshi, all three markets resolve YES regardless of outcome, making Kalshi's structure fundamentally different from standard match betting. Clarify with Kalshi whether this is intentional or a specification error before placing trades.
Critical Divergence Points:
Polymarket: Outlier: Polymarket structures three mutually exclusive binary markets where exactly one outcome (Eibar win, Draw, or Las Palmas win) will resolve YES and the other two resolve NO. The resolution source is official La Liga statistics or credible reporting consensus within 2 hours of match conclusion. Quote: 'If SD Eibar wins, this market will resolve to Yes. Otherwise, this market will resolve to No' (and identical logic for Draw and Las Palmas markets).
Kalshi: Outlier: Kalshi defines three independent markets that each resolve YES if their specific outcome occurs, with no mutual exclusivity constraint. This means all three markets resolve YES simultaneously for any match result (e.g., if Eibar wins, all three Kalshi markets resolve YES). Quote: 'If Eibar wins...then the market resolves to Yes. If Las Palmas wins...then the market resolves to Yes. If Tie wins...then the market resolves to Yes.'
