Polymarket restricts resolution to regulation time plus stoppage (90+ minutes only), while Kalshi includes the entire game duration including extra time. This creates a scope mismatch that will only manifest if the match requires extra time.
Hero Tip:
Monitor whether this Champions League fixture goes to extra time. If it does, Polymarket and Kalshi will resolve to different corner totals. Polymarket bettors are hedged against extra-time corner volatility; Kalshi bettors have full-match exposure. Consider this timing risk when comparing odds across platforms.
Critical Divergence Points:
Polymarket: Offers O/U 8.5 and O/U 10.5 corner markets. Resolution scope is strictly first 90 minutes plus stoppage time only. Extra time and penalty shootout corners are explicitly excluded. Primary source is official UEFA statistics or credible reporting consensus if official stats unavailable within 24 hours. Postponement keeps market open; cancellation resolves 50-50.
Kalshi: Offers five binary Yes/No markets at 7+, 8+, 9+, 10+, and 11+ corner thresholds. Resolution scope includes entire game duration: regulation, stoppage, and any extra time periods. No explicit mention of penalty shootout corners, but extra time is explicitly included. No stated fallback source or postponement/cancellation logic.
