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

Platform comparison

Market context

Dplus KIA face T1 in an LCK Round 3-4 Legend Group best-of-three, and the crowd-implied **49%** for YES is effectively pricing it as a coin flip. That is close to the kind of split you would expect on a two-team market where the favourite is not overwhelming, and it sits below several external previews that have leaned towards T1, including a 58% T1 view on one prediction write-up and 57.8% in a separate match-odds listing.[12][18]

Recent history between these sides matters because it has not been one-way. Dplus KIA beat T1 2-1 in the LCK regular season earlier in 2026, and also recovered from a reverse sweep in the LCK Cup playoffs to eliminate T1 2-3, while a later match result page shows Dplus KIA winning that BO5.[5][3][1] For market readers comparing platforms, Polymarket’s YES line maps directly to the match-winner outcome, whereas books such as Betfair or Smarkets would usually express the same view as decimal odds, with the live price then implying a percentage after fees; in practice, exchange commissions and the user’s KYC access can make a near-50 market trade differently across venues.

The main catalysts before the settlement window are straightforward: any official LCK schedule confirmation, last-minute roster or substitution updates, and whether the series starts on time at all. The listing says the match was initially scheduled for 6 August at 6:00AM ET, so a postponement, cancellation, or a start that is not completed could push the market towards the 50-50 fallback rather than a normal win resolution. A trader should also watch for pre-match line moves from exchange-style markets, because if T1 continues to attract the stronger outside pricing seen in recent previews, Polymarket’s 49% may narrow further before lock.[19][12]
