LoL: Kiwoom DRX vs KT Rolster (BO1) - KeSPA Cup Group Stage

Platform comparison

Market context

Kiwoom DRX and KT Rolster faced off in a single-game Group Stage clash at the 2026 KeSPA Cup on 20 July, with the match already concluded as KT Rolster secured a 1–2 victory in their earlier LCK Best of 3 encounter on 14 May. The prediction market currently shows a 100% implied probability for a DRX win, a figure that starkly contradicts the recent head-to-head result where KT defeated DRX decisively.

Historical precedents in League of Legends prediction markets reveal that 100% implied probabilities often signal settlement errors or data lag rather than genuine certainty, especially when recent form contradicts the line. In comparable cases involving LCK teams, markets with full confidence in one side before a match have frequently resolved to the 50–50 default clause when matches were delayed, forfeited, or when the outcome was already known to be different from the market’s assumption.

Traders should monitor official KeSPA Cup settlement announcements and cross-check live match results on Strafe Esports or EnsiGame to confirm whether the market has failed to update post-match. A recent Strafe listing confirms the match occurred on 20 July, yet the 100% YES line suggests the platform may not have incorporated the KT win from May or the actual Group Stage result, creating a clear divergence between sportsbook consensus, analyst expectations, and the current prediction-market price.
