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

Platform comparison

Market context

Polymarket is pricing **Dplus KIA** at **59%** to beat KT Rolster in this BO3, which means the contract is trading only modestly above a coin flip on the current USDC, Polygon-based conditional token market. For a user, that leaves a fairly balanced setup: if DK win, YES settles at 1.00 USDC per contract; if KT win, it settles at 0, while a no-result outcome under the market rules would push it to 0.50.

That price sits in line with a matchup that has been competitive for some time. Tips.GG’s head-to-head record shows Dplus KIA leading the overall series count 17-12 across 29 LoL meetings, but KT have had the better recent stretch in several samples, including a 78% win rate over the past 30 days versus DK’s 56% on that site’s tracking.[17] Polymarket’s own team page also shows the broader DK market around the same level, with this contract near 62%/39% on adjacent listings, which suggests traders are not treating either side as a strong favourite.[11]

The main catalyst is simply whether the match goes ahead at the scheduled LCK time: Sofascore lists the start for 9 August 2026 at 08:00 UTC, and Polymarket’s market page is already counting down to settlement.[2][1] Traders should watch for any official schedule change, venue or broadcast notice, or format disruption, because this market’s 50-50 fallback only applies if the match is cancelled, ends tied, or is delayed beyond seven days without a winner. A completed forfeit after the match begins would still resolve to the team awarded the win under the rules.

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.
