Polymarket defines three mutually exclusive binary markets (Charlotte win, draw, New York win) where exactly one resolves YES, while Kalshi defines three separate markets that each independently resolve YES if their specific outcome occurs. This creates a logical contradiction: under Kalshi's structure, multiple markets can resolve YES simultaneously for the same match, whereas Polymarket's structure guarantees only one YES resolution.
Hero Tip:
If you trade these markets across both platforms, understand that a single match result will trigger different resolution patterns: Polymarket will have exactly one YES market, but Kalshi may have one or more YES markets depending on the outcome. This means arbitrage opportunities or hedging strategies may not work as expected across platforms. Verify your position structure before settlement.
Critical Divergence Points:
Polymarket:
Distinct stance: Polymarket structures this as three mutually exclusive binary markets where exactly one outcome (Charlotte win, draw, or New York win) resolves YES and the other two resolve NO. The rules explicitly state 'If Charlotte FC wins, this market will resolve to Yes. Otherwise, this market will resolve to No' for the Charlotte market, with identical exclusive logic for the draw and New York markets. This guarantees only one YES resolution across the three markets.
Kalshi:
Distinct stance: Kalshi defines three independent markets, each resolving YES if its specific outcome occurs: 'If Charlotte wins...then the market resolves to Yes', 'If Tie wins...then the market resolves to Yes', and 'If New York wins...then the market resolves to Yes'. This structure allows exactly one market to resolve YES (since only one outcome can occur), but the logical framework treats each market as independently evaluable rather than explicitly mutually exclusive.
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.
