LoL: Nongshim Red Force vs DN SOOPers (BO3) - LCK Round 3-4 Rise Group

Platform comparison

Market context

Polymarket is pricing Nongshim Red Force at **70%** on this BO3, so the contract implies the crowd sees them as a clear favourite, but not a lock. On Polygon, buyers are effectively trading USDC against conditional tokens that settle to $1 if Nongshim win and $0 if DN SOOPers do, with the usual event-risk that a no-result outcome would push resolution to the market’s fallback terms rather than a normal win/loss outcome.[2]

That probability sits between the wider market’s recent reads and the match history. Public pre-match models have leaned more evenly split, with one listing DN SOOPers around 54% and another giving Nongshim roughly 73%, while the most recent available head-to-head result in May went DN SOOPers’ way 2-1 and an earlier LCK meeting in the spring ended 2-0 to Nongshim.[3][4][6][17] For a trader, the practical read is that the current 70% price is consistent with a side that has the stronger overall profile in the market, but one that still carries real BO3 upset risk if the underdog can convert map one into tempo.

The main catalyst is simply whether the series starts on schedule and whether both line-ups are the confirmed starting rosters when the broadcast window opens; Sofascore lists the match for 8 August at 10:00 UTC, which corresponds to the scheduled LCK slot.[1] Because Polymarket settlement here depends on the official match result, traders should watch LCK schedule updates, postponement notices, and any competitive-format changes, since a delay beyond seven days or a non-played match would force the fallback resolution rather than a standard winner payoff.[2]
