LoL: DN SOOPers vs KT Rolster (BO1) - KeSPA Cup Group Stage

Platform comparison

Market context

DN SOOPers face KT Rolster in a single-game KeSPA Cup Group Stage clash originally set for 20 July, with the match now effectively void as the settlement window closes on 20 July at 16:35 UTC. The crowd-implied probability of 0% YES for DN SOOPers suggests the market treats a win for them as impossible, likely reflecting KT’s dominance in recent LCK Cup 21 encounters where KT secured a 2–1 victory after the nexus fell [1]. In comparable Korean league group stages, teams with 0% implied win probability rarely overturn odds unless a roster change or forfeiture occurs, making this a high-confidence bet on KT unless the match was never played.

Traders should monitor official KeSPA Cup announcements for match cancellation notices or forfeiture rulings, as these trigger the 50-50 settlement clause. No recent news has confirmed a delay beyond seven days, but the absence of live coverage post-20 July raises cancellation risk. On Polymarket, this market would show decimal odds of infinity for KT (0% probability), whereas Kalshi, Betfair, and Smarkets typically convert 0% to a minimum tradable price (e.g., 1p or $0.01), creating a divergence in liquidity and fee exposure. Polymarket’s non-KYC access contrasts with Kalshi’s US-only KYC requirement, while Betfair and Smarkets impose higher commission fees on winning trades, affecting net returns on such a low-probability outcome.
