Polymarket defines three mutually exclusive binary markets (Barcelona win, Atlético win, draw), each resolving independently to YES or NO. Kalshi defines a single market that resolves YES for all three possible outcomes (Barcelona win, Atlético win, or draw), making it logically impossible to resolve to NO under any realistic match scenario.
Hero Tip:
Do not trade these markets as equivalent. Polymarket offers three separate binary bets where exactly one will resolve YES and two will resolve NO. Kalshi's market will almost certainly resolve YES regardless of the match result, making it fundamentally different in risk/reward profile. Avoid arbitrage assumptions between platforms.
Critical Divergence Points:
Polymarket: Distinct stance: Polymarket creates three separate binary markets covering all possible outcomes (Barcelona win, Atlético win, draw). Each market resolves YES or NO independently based on the actual match result. Only one of the three will resolve YES; the other two resolve NO. Key quote: 'If FC Barcelona wins, this market will resolve to Yes. Otherwise, this market will resolve to No' (and identical logic for Atlético and draw markets).
Kalshi: Outlier: Kalshi defines a single market with three resolution conditions all mapped to YES: 'If Tie wins...then the market resolves to Yes. If Barcelona wins...then the market resolves to Yes. If Atletico wins...then the market resolves to Yes.' This structure provides no NO resolution path for any realistic match outcome, creating a market that is logically equivalent to a guaranteed YES payout.
