LoL: KT Rolster Challengers vs DN SOOPers Challengers (BO3) - LCK Challengers League Rounds 3-4 Challenge Group

Platform comparison

Market context

KT Rolster Challengers and DN SOOPers Challengers are due to meet in a best-of-three in the LCK Challengers League’s Rounds 3-4 Challenge Group, and the market is pricing a near-certainty on the KT side with a 100% YES readout. That stands well above the more conventional pre-match pricing seen elsewhere: Polymarket’s own listing shows the series split at roughly 50-50, while Kalshi has KT Rolster Challengers around 57% and DN SOOPers Challengers around 43%[11][15]. For a BO3 in a developmental league, that kind of spread usually signals either a stale line, thin liquidity, or an information gap rather than a truly unanimous view.

The comparison case points towards KT being the more established side in this pairing. Recent head-to-head results show KT Rolster Challengers beat DN SOOPers Challengers 2-0 earlier in the 2026 LCK CL season, and the broader match records in April also favour KT in direct meetings[3][5][8]. That makes the current 100% market print look especially aggressive relative to historical form, because even one-sided rematches in academy leagues usually retain some upset risk over a BO3 format. In practical terms, the current probability is only hard to read as a genuine consensus if multiple venues are all seeing the same team-news edge.

The main catalysts to watch are roster confirmation, whether the series starts on schedule, and any late schedule changes tied to the official LCK Challengers broadcast feed. The match page on Sofascore and the league’s live channels indicate the fixture was set for this morning UTC, so traders should focus on whether line-ups are locked in and whether the series is actually underway before the settlement window closes[1][16]. If the event slips beyond the seven-day rule or is not played, the market can resolve away from either team, which matters more here than usual given the extreme 100% reading on one outcome.
