LoL: Kiwoom DRX vs DN SOOPers (BO3) - LCK Round 3-4 Rise Group

Platform comparison

Market context

Polymarket is pricing Kiwoom DRX at **64%** against DN SOOPers in this LCK Rise Group best-of-three, with settlement paid in **USDC** through **Polygon** conditional tokens once the match result is official. That is above a simple coin-flip and suggests traders currently see Kiwoom DRX as the more likely winner, but not by enough to imply a clean mismatch.

The current number sits in line with comparable market reads that have often placed Kiwoom DRX in the high-50s to high-60s for this pairing, including recent third-party previews around the 57% to 62% range. The broader setup matters too: the teams are in the lower half of the Rise Group, where every BO3 has direct implications for progression, so traders tend to treat regular-season form and series reliability as more important than raw name value when assessing the contract.[2][4][15]

For traders, the main catalysts are the confirmed line-ups, any schedule changes, and whether the series starts on time at the listed window, since a cancellation, no-contest or delay beyond seven days would push the market to 50-50 under Polymarket’s rules. Because the market only resolves on the match winner if the BO3 is completed, any forfeit, default or partial series outcome can matter materially, so the practical focus is less on live map swings and more on official LCK announcements and broadcast status near start time.[1]
