Polymarket structures three separate binary markets (Athletic Club win, Draw, Villarreal win) that are mutually exclusive and collectively exhaustive, while Kalshi presents three separate YES/NO markets that each resolve YES for any of the three possible outcomes, creating a logical contradiction where all three Kalshi markets would resolve YES simultaneously.
Hero Tip:
If you trade on Kalshi, understand that all three markets will resolve YES regardless of the match outcome—this is not a typical three-way split. Polymarket's structure is standard: exactly one of the three markets resolves YES. Do not assume Kalshi behaves like Polymarket.
Critical Divergence Points:
Polymarket:
Outlier: Polymarket uses a mutually exclusive three-way structure where exactly one market resolves YES based on the final 90-minute result. Each market (Athletic Club win, Draw, Villarreal win) resolves NO if its specific outcome does not occur. Key quote: 'If Athletic Club wins, this market will resolve to Yes. Otherwise, this market will resolve to No.'
Kalshi:
Outlier: Kalshi presents three separate markets, each of which resolves YES if any of the three possible outcomes occurs (Tie, Bilbao win, or Villarreal win). This means all three Kalshi markets will resolve YES simultaneously after the match, regardless of result. Key quote: 'If Tie wins...then the market resolves to Yes. If Bilbao wins...then the market resolves to Yes. If Villarreal wins...then the market resolves to Yes.'
