Polymarket defines three mutually exclusive binary markets (Portland win, LAFC win, draw) where exactly one resolves YES, while Kalshi defines three markets that all resolve YES regardless of outcome, creating a logical contradiction that makes Kalshi's markets fundamentally unresolvable.
Hero Tip:
Do not trade Kalshi markets in this group. Kalshi's three markets all resolve to YES for any match outcome (tie, Portland win, or LAFC win), which violates basic market logic and creates arbitrage confusion. Polymarket's three binary markets are logically sound: exactly one will resolve YES. Trade only Polymarket if you must participate in this event group.
Critical Divergence Points:
Polymarket: Aligned with standard soccer market logic: Polymarket defines three mutually exclusive binary outcomes where exactly one market resolves YES based on the 90-minute result. Portland win market resolves YES if Portland wins, LAFC win market resolves YES if LAFC wins, and draw market resolves YES if the match ends in a draw. All three use the same primary resolution source: official MLS statistics or credible reporting consensus within 2 hours of match conclusion.
Kalshi: Outlier: Kalshi defines three separate markets that each resolve YES for any outcome. Market 1 resolves YES if 'Tie wins OR Portland wins OR Los Angeles F wins', Market 2 resolves YES if 'Portland wins OR Tie wins OR Los Angeles F wins', and Market 3 resolves YES if 'Los Angeles F wins OR Portland wins OR Tie wins'. All three markets cover all possible outcomes, meaning all three will resolve YES simultaneously regardless of the actual match result, creating a logical impossibility.
