LoL: Dplus KIA vs KT Rolster (BO3) - LCK Round 3-4 Legend Group

Platform comparison

Market context

Dplus KIA and KT Rolster meet in a best-of-three LCK Legend Group series, and the market’s 59% YES price sits close to the teams’ longer-run head-to-head edge rather than implying a dominant favourite. Across 29 listed meetings, Dplus KIA have won 17 and KT Rolster 12, with Dplus holding a 40-34 map advantage overall; however, the recent split is tighter, with six meetings over the last 12 months shared 3-3 and KT slightly ahead on maps in that period.[4] Polymarket’s own team pricing has also kept Dplus only modestly favoured at around 62% on the match line, which is broadly consistent with the current crowd view.[6]

For a power-user, this is the sort of market that is best handled with event-driven automation rather than discretionary watching: schedule-confirmation alerts, line-up or pause-state monitoring, and conditional orders keyed to any official delay or format change matter as much as pre-match form. Recent Korean esports coverage has also shown KT in competitive shape, with a win over T1 and Hanwha Life pushing them further into the top-spot race, which supports the idea that this is not a soft spot for Dplus even if historical results lean their way.[16] The main catalysts to watch are the start time, whether the BO3 begins on schedule, and whether any broadcast or league announcement changes the settlement path, because a match not played, tied, or delayed beyond seven days resolves 50-50 under the market rules.[3]

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.

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.
