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

Platform comparison

Market context

KT Rolster face T1 in a best-of-three League of Legends match within the LCK's Legend Group stage, scheduled for 21 August 2026. The conditional token on Polymarket currently prices KT's victory at 37 cents per USDC, implying a 37% win probability. This valuation reflects T1 as the favoured side, though the market has absorbed limited liquidity relative to marquee LCK fixtures, suggesting room for repricing as match day approaches.

Historically, T1 command a significant head-to-head advantage over KT Rolster in recent LCK seasons, winning roughly 60–65% of their encounters since 2023. However, KT have demonstrated capacity to upset T1 in isolated fixtures, particularly when fielding strong mid-lane and jungle synergy. The current 37% probability sits below KT's typical upset range in comparable matchups, suggesting the market may be overweighting T1's structural advantages or underestimating KT's current roster form. Traders should cross-reference recent LCK standings and individual player performance metrics—particularly jungle proximity and vision control metrics—to calibrate whether this pricing reflects genuine form divergence or market inertia.

The settlement window closes 21 August at 16:00 UTC, allowing approximately ten hours post-match for result confirmation. Cancellation or postponement triggers a 50-50 resolution; any rescheduling must occur by 4 September 2026. Traders should monitor LCK official announcements for roster changes, injury updates, or scheduling shifts in the fortnight preceding the fixture. Recent patch notes affecting champion viability may also shift team preparation priorities and should be tracked via Riot's official patch release schedule.
