Platform comparison

Active sub-markets

Market context

KT Rolster and T1 are scheduled to meet in a best-of-three League of Legends match during LCK Rounds 1-2 on 28 May at 6:00 AM ET. The market currently prices KT at 44 per cent implied probability, positioning T1 as the favoured side. This represents a significant underdog valuation for KT, a team that has historically competed at the highest level of Korean League play, though T1's sustained dominance in the LCK and international scene justifies their status as consensus favourite.

Historical matchups between these organisations show T1 winning the majority of recent encounters, reinforcing the current probability distribution. However, KT's performance trajectory within the 2026 season, roster stability, and recent form against comparable opponents should anchor any reassessment. The 44 per cent line suggests the market has already priced in T1's superior track record and current standing, leaving limited room for contrarian positioning unless KT has demonstrated unexpected strength in preceding matches or roster changes have materially altered competitive balance.

Traders should monitor official LCK scheduling confirmations and any last-minute roster announcements in the days preceding the match. Injury reports, substitute deployments, or coaching changes could shift the probability landscape. The settlement window closes at 16:00 UTC on 28 May, providing a tight window for match completion; any delays beyond seven days trigger a 50-50 resolution. Recent LCK broadcasts have maintained reliable scheduling, though technical issues or unforeseen circumstances remain possible catalysts for market volatility.

Methodology

We track LoL: KT Rolster vs T1 (BO3) - LCK Rounds 1-2 on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
