Polymarket defines three mutually exclusive binary markets (Union win, Draw, Riestra win) where exactly one resolves YES, while Kalshi defines a single market that resolves YES for ALL three possible outcomes (Union win, Draw, or Riestra win). This creates a fundamental logical contradiction: Kalshi's market cannot fail to resolve YES under any realistic match scenario.
Hero Tip:
Do not trade Kalshi's market as written—it is logically unresolvable. If you hold a YES position on Kalshi, the market will resolve YES regardless of the match result, making it a guaranteed payout. If you hold NO, you will lose. Polymarket's three separate binary markets are logically sound and mutually exclusive. Clarify with Kalshi whether their market should resolve YES only if a specific outcome occurs (e.g., Draw only), or if the market description is an error.
Critical Divergence Points:
Polymarket: Distinct stance: Polymarket offers three separate binary markets covering all possible outcomes (Union win, Draw, Riestra win). Each market resolves YES or NO independently based on a single outcome. Exactly one market will resolve YES. Quote: 'If CA Unión wins, this market will resolve to Yes. Otherwise, this market will resolve to No' (Union market); 'If the game ends in a draw, this market will resolve to Yes. Otherwise, this market will resolve to No' (Draw market); 'If CD Riestra wins, this market will resolve to Yes. Otherwise, this market will resolve to No' (Riestra market).
Kalshi: Outlier: Kalshi presents a single market with three resolution conditions all mapped to YES: 'If Tie wins...then the market resolves to Yes. If Riestra wins...then the market resolves to Yes. If Union Santa Fe wins...then the market resolves to Yes.' This means the market resolves YES for every possible match outcome, making NO resolution impossible under normal circumstances.
