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

Platform comparison

Market context

KT Rolster Challengers face DN SOOPers Challengers in a best-of-three LCK Challengers League group match, and the market is pricing the favourite at **100% implied probability** for KT. That is far more extreme than the most recent comparable head-to-head read: KT beat DN SOOPers 2-0 in their April meeting, with SofaScore and GosuGamers both recording a straight-series win for KT, and Polymarket’s earlier spring listing describing KT as the stronger side on form and standings. Those comparisons support the consensus side, but a 100% line leaves no room for variance, draft swings, or a map drop in a BO3.

For a handicapper, the main question is not who is better, but whether the market has already priced in nearly every plausible edge. KT’s prior clean win is the obvious anchor for the favourite case, while DN’s only route to value is as a contrarian on short-series volatility if the teams have narrowed since the spring split. The market on Polymarket is scheduled around July 31 at 1:00 AM ET, and the contract also says a cancellation or delay beyond seven days resolves 50-50, so schedule risk matters if the fixture is moved or not played. Traders should watch the official LCK Challengers broadcast and match page for start-time confirmation, roster changes, or any late bracket adjustments before lock.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
