Polymarket structures three mutually exclusive binary markets (Sporting CP win, Arsenal FC win, draw), while Kalshi presents three non-mutually-exclusive YES/NO markets that all resolve YES regardless of outcome. Kalshi's structure is logically contradictory and unresolvable.
Hero Tip:
Do not trade Kalshi markets in this group. Kalshi's three markets will all resolve YES simultaneously after the match concludes, making them worthless for prediction. Polymarket's three markets are mutually exclusive and properly structured — exactly one will resolve YES. Trade only on Polymarket.
Critical Divergence Points:
Polymarket:
Outlier: Polymarket creates three mutually exclusive binary markets where exactly one resolves YES based on the match outcome (Sporting CP win, Arsenal FC win, or draw). Each market explicitly resolves NO for all other outcomes. Key quote: 'If Sporting CP wins, this market will resolve to Yes. Otherwise, this market will resolve to No.'
Kalshi:
Outlier: Kalshi presents three markets that all resolve YES regardless of match outcome. Market 1 resolves YES if Sporting CP wins OR if Tie wins OR if Arsenal wins. Markets 2 and 3 repeat the same logic. Key quote: 'If Sporting CP wins... then the market resolves to Yes. If Tie wins... then the market resolves to Yes. If Arsenal wins... then the market resolves to Yes.'
