Polymarket uses three separate binary markets with asymmetric cancellation logic (draw YES, wins NO), while Kalshi uses a single three-outcome market with no explicit cancellation clause. This creates structural incompatibility in edge case resolution.
Hero Tip:
Traders holding positions across both platforms face basis risk in cancellation scenarios. Polymarket's draw market has asymmetric payoff if canceled (YES), while win markets pay NO. Kalshi's cancellation behavior is undefined. Recommend monitoring CONMEBOL official channels and requesting explicit Kalshi cancellation guidance before April 29, 2026.
Critical Divergence Points:
Polymarket: Three independent binary markets with asymmetric cancellation logic. Draw market resolves YES if canceled; win markets resolve NO if canceled. All three markets reference 90 minutes plus stoppage time, with official CONMEBOL statistics as primary source and credible reporting as fallback within 2 hours of conclusion.
Kalshi: Single unified market covering three outcomes (Santa Fe win, Platense win, Tie). Resolves YES for whichever outcome occurs within 90 minutes plus stoppage time. No explicit cancellation or postponement clause provided in source material.
