Polymarket defines three separate binary markets (draw, Rio Ave win, Santa Clara win) that partition all possible outcomes, while Kalshi defines three markets that each resolve YES for any outcome (draw, Rio Ave win, or Santa Clara win), creating fundamentally different settlement structures.
Hero Tip:
On Polymarket, exactly one of the three markets will resolve YES. On Kalshi, all three markets will resolve YES regardless of the match result. If you are hedging across platforms, understand that Kalshi's structure means you cannot use it to offset Polymarket positions — all Kalshi markets move together to YES.
Critical Divergence Points:
Polymarket: Distinct stance: Polymarket creates three mutually exclusive binary markets where exactly one resolves YES based on the match outcome (draw YES/others NO, Rio Ave win YES/others NO, Santa Clara win YES/others NO). Each market explicitly resolves NO if its condition is not met: 'If the game ends in a draw, this market will resolve to Yes. Otherwise, this market will resolve to No' and 'If Rio Ave FC wins, this market will resolve to Yes. Otherwise, this market will resolve to No.'
Kalshi: Distinct stance: Kalshi creates three markets that each resolve YES for any match outcome — one YES if Santa Clara wins, one YES if Rio Ave wins, one YES if there is a tie. The structure states 'If Santa Clara Azores wins...then the market resolves to Yes' and 'If Rio Ave wins...then the market resolves to Yes' and 'If Tie wins...then the market resolves to Yes,' meaning all three markets will simultaneously resolve YES regardless of the result.
