LoL: KT Rolster vs T1 (BO3) - LCK Round 3-4 Legend Group

Platform comparison

Market context

KT Rolster and T1 are scheduled to meet in a best-of-three League of Legends match within the LCK's Round 3–4 Legend Group phase on 21 August 2026. The current crowd-implied probability of 37% for a KT Rolster victory reflects a substantial underdog position relative to T1, one of the region's most decorated franchises. Settlement occurs at 16:00 UTC on the match date, with a 14-day postponement window extending to 4 September 2026.

Historically, T1 has dominated head-to-head records against KT Rolster across multiple seasons, though the gap has narrowed during periods when KT fielded competitive rosters. The 37% implied probability sits notably lower than typical sportsbook spreads for similarly-ranked LCK matchups, suggesting either market undervaluation of KT's current form or overconfidence in T1's consistency. Recent LCK seasons have shown increased volatility in Legend Group standings, with mid-tier teams occasionally upsetting favourites during round-robin phases.

Traders should monitor roster announcements and injury reports through early August, particularly regarding T1's mid and ADC positions, which have experienced turnover. LCK broadcast schedules occasionally shift due to production constraints; any rescheduling before the 4 September deadline would not affect market resolution but could alter preparation time for either team. Recent patch notes affecting champion viability in professional play typically drop weeks before matches, providing clarity on meta direction that could favour either squad's preparation strengths.

The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
