Kalshi's market structure is logically incoherent: all three possible match outcomes (Osasuna win, Tie, Alaves win) are listed as separate resolution conditions that each resolve to Yes, making it impossible for the market to function as a binary contract. Polymarket correctly structures three separate binary markets (one per outcome). This is a fundamental data integrity failure on Kalshi.
Hero Tip:
Do not trade Kalshi's markets in this group — they are unresolvable as written. The platform appears to have published three mutually exclusive outcomes as a single market contract, which violates basic prediction market logic. Polymarket's three separate binary markets are the only tradeable contracts in this event group.
Critical Divergence Points:
Polymarket: Aligned with sound market design: Polymarket correctly structures three separate binary markets, one for each outcome (Alaves win, Draw, Osasuna win). Each market resolves YES or NO independently based on the actual match result. Resolution source is official La Liga statistics within 2 hours post-match, or credible reporting consensus if official data is delayed. Cancellation without makeup resolves NO for win markets and YES for draw market.
Kalshi: Outlier — critical structural failure: Kalshi lists three mutually exclusive outcomes (Osasuna win, Tie, Alaves win) as separate resolution conditions within what appears to be a single market, each stating 'resolves to Yes.' This creates a logical impossibility: only one outcome can occur, so only one condition can be true, yet the market structure suggests all three are independent Yes/No triggers. The market is unresolvable as written and contains no cancellation or postponement rules.
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.
