Polymarket settles on three binary outcomes (draw, Pumas win, Mazatlán win) covering all possible match results, while Kalshi settles on four goal-differential thresholds that create overlapping and mutually exclusive scenarios. The platforms use fundamentally different resolution scopes: Polymarket covers the complete outcome space with mutually exclusive markets, whereas Kalshi's markets can resolve YES simultaneously for different goal margins.
Hero Tip:
If you trade on Polymarket, exactly one of the three markets will resolve YES. On Kalshi, multiple markets can resolve YES in the same match (e.g., if Pumas wins 3-0, both 'Pumas wins by more than 1.5' and 'Pumas wins by more than 2.5' resolve YES). Do not assume Kalshi markets are mutually exclusive like Polymarket's.
Critical Divergence Points:
Polymarket: Distinct stance: Polymarket uses three mutually exclusive binary markets covering all possible outcomes—draw, Pumas win, or Mazatlán win—each resolving YES or NO based on the final 90-minute result. 'If the game ends in a draw, this market will resolve to Yes. Otherwise, this market will resolve to No.' Exactly one market resolves YES per match.
Kalshi: Distinct stance: Kalshi uses four goal-differential threshold markets that are not mutually exclusive. Markets resolve YES if either team wins by a specified margin (Mazatlán >1.5, Mazatlán >2.5, Pumas >1.5, Pumas >2.5). Multiple Kalshi markets can resolve YES simultaneously in the same match, and all four can resolve NO if the match ends in a draw or with a 1-goal margin. 'If Mazatlan wins by more than 1.5 goals...then the market resolves to Yes.'
