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 on 21 August 2026. The 37% implied probability for KT victory reflects T1's historical dominance in head-to-head fixtures and their standing as the region's most decorated franchise, though recent roster adjustments and mid-season form shifts have narrowed the gap between these two organisations considerably.

Historically, T1 hold a significant advantage in direct matchups against KT Rolster across multiple seasons, winning roughly 60–65% of their encounters in recent years. However, the LCK's competitive landscape has shifted noticeably since 2024, with KT demonstrating improved macro play and team cohesion under their current coaching staff. The 37% probability suggests the market is pricing in T1 as clear favourites whilst acknowledging KT's capacity to execute in best-of-three formats, where preparation depth and mid-series adjustments carry greater weight than single-game variance.

Traders should monitor LCK broadcast schedules and any roster announcements in the fortnight preceding the match, particularly regarding player health or last-minute line-up changes. Recent patch notes affecting champion viability and jungle pathing will influence champion select strategy significantly. The settlement window closes at 16:00 UTC on 21 August, with a two-week postponement window available should scheduling conflicts arise. Any cancellation or tie resolves the market to 50-50, a material tail risk given the LCK's occasional fixture congestion during summer playoffs.
