Polymarket lacks published resolution rules while Kalshi provides comprehensive coverage. This creates source fragility and prevents cross-platform consistency verification, though the underlying event (match result) is objective and resolvable.
Hero Tip:
Use Kalshi's rules as your reference framework: resolution occurs at the 90-minute mark plus stoppage time, excluding extra time and penalties. Before trading Polymarket, obtain explicit confirmation that it follows identical logic. Monitor for any platform-specific tie-handling or cancellation procedures that may diverge.
Critical Divergence Points:
Kalshi: Comprehensive three-outcome coverage with explicit temporal boundary. All outcomes (LAFC win, Toluca win, tie) resolve Yes if they occur after 90 minutes plus stoppage time in the Apr 29, 2026 CONCACAF Champions Cup match. Key Quote: 'does not include extra time or penalties'.
Polymarket: No detailed rules published. Resolution logic, outcome coverage, and temporal boundaries are undisclosed, creating information asymmetry.
