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

Platform comparison

Market context

DN SOOPers face KT Rolster in a single-game Group Stage clash at the KeSPA Cup, with the match originally slated for 5:45AM ET on 20 July. The current crowd-implied probability of 0% YES for a SOOPers win suggests the market views KT as an overwhelming favourite, a stance that diverges sharply from platforms using decimal odds where such a one-sided view might still show a non-zero price rather than a flat zero probability.

Historical LCK Cup encounters between these sides show KT’s dominance, including a recent 2-1 victory in the LCK Cup 2026 where KT secured the nexus and the match win, reinforcing the pattern of their superiority in high-stakes Group Stage fixtures [1]. On Polymarket, this 0% implied probability reflects a binary consensus, whereas Betfair or Smarkets would likely display a decimal odds figure above 1.00, preserving a minimal chance and differing in fee structures that can alter the effective payout for such extreme outcomes.

Traders should monitor official KeSPA Cup schedule updates for any postponements beyond the seven-day resolution window, as delays could trigger the 50-50 settlement clause, and watch for team announcements regarding roster changes or forfeits that might alter the outcome before the match begins. No recent news source has reported a cancellation, but the tight settlement window ending 2026-07-20T16:35:00Z means any delay past this point without a winner will reset the market to an even split, a nuance Kalshi’s KYC-heavy model may handle differently than Polymarket’s permissionless approach.
