Active sub-markets

Market context

KT Rolster and T1 are scheduled to face each other in a League of Legends Champions Korea (LCK) best-of-three match on 28 May 2026 at 06:00 ET. The current 44% implied probability for a KT victory reflects T1's historical dominance in the region, though the fixture carries meaningful uncertainty given roster volatility and mid-season form. Settlement occurs at the match conclusion, with a 50-50 resolution triggered only if the match is cancelled outright, extends beyond seven days without completion, or ends in a formal tie—an exceptionally rare outcome in LCK play.

T1 have won four of the last five LCK championships and maintain the region's strongest brand recognition globally, yet KT Rolster have periodically challenged that supremacy, most recently in 2022 when they reached the LCK finals. The 44% probability suggests traders are pricing in meaningful competitive parity rather than a T1 coronation, a stance consistent with how Polymarket's order-book pricing typically reflects tighter spreads than fixed-odds operators like Betfair or Kalshi on regional esports fixtures where Western liquidity is thinner. Kalshi's decimal-odds display (roughly 2.27 for a KT win at 44%) may appeal to traders accustomed to European betting conventions, whilst Polymarket's probability format suits direct comparison across multiple esports markets.

Roster changes and scrim results in the weeks preceding 28 May will be critical signals; LCK teams often adjust compositions mid-season in response to meta shifts. Monitor official LCK announcements regarding player availability and any schedule delays, as the seven-day grace period in the resolution criteria creates a narrow window where ambiguity could trigger a 50-50 split. Recent patch notes and international tournament results (should any occur between now and the match) may also shift trader positioning, particularly if either team's key players compete elsewhere immediately beforehand.

Methodology

We read LoL: KT Rolster vs T1 (BO3) - LCK Rounds 1-2 from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). Polymarket Alternative routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
