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

Platform comparison

Market context

Dplus KIA’s BO3 with KT Rolster in the LCK Legend Group has been priced close to a coin-flip, with the market’s 59% YES sitting just under Polymarket’s listed Dplus KIA price of 62%. That gap is modest, but it still matters in a match where recent head-to-head form has swung both ways: Tips.GG records Dplus KIA leading the all-time series 17-12, while the map score is narrower at 40-34, and the teams split their last six meetings 3-3. Recent match pages also show KT taking the most recent 2026 series 2-0, which helps explain why the crowd has not pushed Dplus much higher despite the historical edge.[4][6][9][13]

For traders, the key catalyst is simple scheduling risk: the market resolves at the match outcome if the series is played, but drops to 50-50 if it is cancelled, tied, or delayed more than seven days beyond the scheduled date. That makes official LCK start-time confirmation, venue status, and any broadcast or fixture changes the main watchpoints, especially given that esports markets can move on postponement chatter before the first draft appears. The broader team context is also relevant: KT were reported to have beaten top domestic opposition in early August, reinforcing the view that this is not a one-sided fixture, while Polymarket’s own derivatives imply a relatively balanced game state, with Dplus at 56% for Game 1 and 56% for Game 2, but only 34% for a 2-0 cover.[15][6]

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.
