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 2026, originally set for 5:45 AM ET on 20 July. The prediction market currently implies a 0% chance for DN SOOPers to win, a stark divergence from community voting data where KT Rolster holds 95.2% support on Strafe Esports, while another platform shows a 50% split, suggesting significant cross-platform pricing inefficiency [1][2].

Historical precedents in League of Legends prediction markets often show that 0% implied probabilities for a named team signal either a confirmed roster absence or a pre-match forfeiture rather than genuine competitive inferiority. Comparable cases in regional tournaments reveal that when sportsbook lines or community votes heavily favour one side but prediction markets collapse to zero, the contract frequently resolves to the 50-50 cancellation clause if the match fails to start, rather than a decisive loss for the favoured team.

Traders must monitor official KeSPA Cup announcements regarding roster validity and match completion status, as the settlement window closes on 20 July 2026 with a seven-day delay clause for unresolved fixtures. Recent coverage confirms the match was scheduled but highlights the volatility in community sentiment versus market pricing, making the cancellation clause the primary risk vector if KT Rolster’s dominance is not reflected in a completed game [1]. Any delay beyond the seven-day threshold or a forfeiture will trigger the 50-50 resolution, overriding the current 0% implied probability for DN SOOPers.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
