Platform comparison

Active sub-markets

Market context

KT Rolster face DN SOOPers in a best-of-three LCK fixture scheduled for 30 May at 04:00 ET. The 100% crowd probability reflects KT's standing as a historically dominant LCK organisation with multiple championship titles, whilst DN SOOPers remain a lower-tier franchise with minimal competitive pedigree in the region's top division. No roster changes or injury reports have emerged in the past 48 hours that would materially alter the expected outcome.

KT's recent form and institutional resources create a structural asymmetry that underpins the extreme probability. The organisation has consistently fielded competitive squads capable of competing at Worlds, whereas DN SOOPers have cycled through multiple rosters without establishing sustained success. Historical matchups between top-tier and lower-tier LCK teams typically favour the established organisation by margins exceeding 80–90% win rates over extended sample periods.

The settlement window closes at 14:00 UTC on 30 May, allowing seven days for completion before the 50-50 tie resolution triggers. Traders should monitor the LCK official schedule for any last-minute postponements or technical issues that might delay the match beyond the deadline. Confirmation of both teams' final rosters and any late-stage player availability announcements from either organisation would be the primary catalysts to track before fixture start.
