LoL: Dplus KIA vs T1 (BO3) - LCK Round 3-4 Legend Group

Platform comparison

Market context

Dplus KIA’s latest swing against T1 came in February, when they won the LCK Cup 2026 playoff series 2-3 after a reverse sweep, but T1 answered with a 2-0 league win in May in the 2026 rounds. That split recent record is the main reason the market sits close to parity at 49% YES: the teams have traded momentum, and neither side has established a clean edge in the current season’s head-to-heads. [3][10][5]

Longer-term, T1 still carries the stronger comparative profile. Head-to-head summaries list T1 ahead overall, with more series wins and a larger cumulative map score, even though Dplus KIA have taken some of the more recent and more consequential meetings. For a best-of-three, that history usually keeps T1 priced as the narrower favourite unless recent form or draft trends point sharply the other way. [15][6][12]

The key near-term catalyst is whether the match starts as scheduled and under standard LCK conditions, because any cancellation, tie, or delay beyond seven days would push the market to 50-50 by the rules. If the series is played, traders will watch official LCK scheduling updates, pre-match roster confirmations and any late changes to patch or venue conditions, since these are the main events that can move a short-dated esports market before the first draft.
