Polymarket and Kalshi define contradictory resolution outcomes in the event of match cancellation with no make-up game. Polymarket's draw market resolves "Yes" on cancellation, while its win markets resolve "No"; Kalshi provides no explicit cancellation guidance, creating ambiguity and potential settlement failure.
Hero Tip:
Do not trade these markets until cancellation protocol is unified. If you hold positions, contact both platforms immediately post-event to confirm whether the match was completed or canceled, and demand explicit settlement confirmation in writing. Polymarket's asymmetric cancellation logic (draw=Yes, wins=No) is a structural flaw that may trigger disputes.
Critical Divergence Points:
Polymarket: Three separate binary markets: Racing Club win, Caracas FC win, and draw. All resolve based on official CONMEBOL statistics or credible reporting within 2 hours of match end. Cancellation rule: Racing win and Caracas win resolve "No" if canceled with no make-up; draw resolves "Yes" if canceled with no make-up. Key quote: 'If the game is canceled entirely, with no make-up game, this market will resolve "No"' (win markets) vs. 'this market will resolve "Yes"' (draw market).
Kalshi: Three markets bundled as a single event: Tie, Caracas win, or Racing Avellaneda win. All three resolve "Yes" if the match occurs and produces the specified outcome after 90 minutes plus stoppage time. No explicit cancellation clause provided. Key quote: 'If [outcome] wins the Caracas vs Racing Avellaneda professional CONMEBOL Sudamericana soccer game originally scheduled for Apr 29, 2026 after 90 minutes plus stoppage time, then the market resolves to Yes.' Silence on cancellation creates settlement ambiguity.
