LoL: DN SOOPers Challengers vs T1 Academy (BO3) - LCK Challengers League Rounds 3-4 Challenge Group

Platform comparison

Market context

Polymarket is pricing DN SOOPers Challengers at **36%** to beat T1 Academy in this BO3, with the contract settled in **USDC on Polygon** through conditional tokens, so the market is effectively asking whether the underdog can take the series before the 7-day delay rule or any no-contest outcome pushes it to 50-50.

That price sits against a split historical picture. T1 Academy have generally been the stronger side in the 2026 standings and entered the matchup with a reported 80% series win rate and top placement in the Challenge Group, while DN SOOPers Challengers did beat Dplus KIA Challengers 2-0 in their most recent listed result. The head-to-head also matters: the teams met earlier in 2026, with T1 Academy winning one series and DN SOOPers Challengers taking another across recent meetings, which is consistent with a market that does not treat this as a one-way spot. The earlier April meeting also went the distance, ending 2-1 to T1 Academy, which supports a view that the underdog can stay live even when not favoured.

For traders, the main catalysts are simple: final roster confirmation, any schedule slippage, and whether the match starts on the listed broadcast window. The event was posted for 6 August at 05:00 UTC, and live schedule pages around the league show the same pairing in the Round 3-4 Challenge Group, so the main binary is still whether the series is played cleanly and who has the sharper draft and early-game execution once champ select begins.
