This event group covers the outcome of a CONCACAF Champions Cup soccer match between Seattle Sounders FC and Tigres de la UANL originally scheduled for April 15, 2026. Resolution is determined by the final score after 90 minutes of regulation play plus stoppage time, excluding any extra time or penalty shootout.
Kalshi's three markets create a logical contradiction: all three outcomes (Seattle win, Tigres win, tie) are marked to resolve YES, making it impossible for exactly one market to resolve YES. Polymarket's three markets are logically coherent and mutually exclusive. This is a data integrity failure on Kalshi.
Hero Tip:
Do not trade Kalshi markets in this group until the contradiction is resolved. Kalshi's resolution rules guarantee that all three outcomes cannot simultaneously occur, yet all three markets are written to resolve YES. Polymarket's markets are tradeable and follow standard mutually-exclusive logic: exactly one of Seattle win, Tigres win, or draw will resolve YES.
Critical Divergence Points:
Kalshi:
Outlier: Contains a logical contradiction. All three markets (Seattle win, Tigres win, tie) are written to resolve YES for their respective outcomes, but only one outcome can occur in a single match. The rules state 'If Seattle wins... then the market resolves to Yes' AND 'If Tigres wins... then the market resolves to Yes' AND 'If Tie wins... then the market resolves to Yes', making it impossible to determine which market should actually resolve YES when the match concludes.
Polymarket:
Aligned with standard market logic: Provides three mutually exclusive markets with coherent resolution. Market 1 resolves YES only if Seattle wins, NO otherwise. Market 2 resolves YES only if the match ends in a draw, NO otherwise. Market 3 resolves YES only if Tigres wins, NO otherwise. Exactly one market will resolve YES based on the actual match outcome.
