Kalshi's market structure is logically contradictory and unresolvable. Kalshi states that YES resolves if Botafogo wins OR Coritiba wins OR a tie occurs—covering all possible outcomes—making it impossible for the market to resolve NO. Polymarket offers three separate, mutually exclusive markets (Botafogo win, Coritiba win, draw) with standard binary resolution, which is logically sound and consistent with soccer match outcomes.
Hero Tip:
Do not trade the Kalshi market. Its resolution rules guarantee YES regardless of the match result, rendering it a broken contract. Trade only Polymarket's three markets, which correctly partition all possible outcomes (Botafogo win, Coritiba win, or draw) and resolve independently based on the actual match result.
Critical Divergence Points:
Kalshi:
Outlier: Kalshi's market contains a fatal logical flaw. All three resolution conditions (Botafogo wins, Coritiba wins, or tie) resolve to YES, meaning the market will resolve YES regardless of the actual match outcome. The market rules state 'If Botafogo wins...then the market resolves to Yes' AND 'If Coritiba wins...then the market resolves to Yes' AND 'If Tie wins...then the market resolves to Yes,' leaving no scenario for a NO resolution.
Polymarket:
Aligned with standard market logic: Polymarket correctly structures three independent binary markets—one for each possible outcome (Botafogo win, Coritiba win, draw). Each market resolves YES only if its specific outcome occurs and NO otherwise. For example, the Botafogo win market states 'If Botafogo FR wins, this market will resolve to Yes. Otherwise, this market will resolve to No,' ensuring exactly one market resolves YES and two resolve NO after the match.
