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

Platform comparison

Market context

KT Rolster and Dplus KIA have already met in this LCK cycle, and the latest result went to Dplus KIA by 2-1 after KT took the opening map but dropped the next two, which is consistent with a fairly even head-to-head rather than a dominant favourite. Historical series data also leans only modestly towards Dplus KIA overall: one archive puts the matchup at 17 wins to 12 across 29 meetings, with the map score 40-34 in Dplus KIA’s favour, while recent year-on-year form has been closer to split. That helps explain why a market price around 41% for KT looks like a live underdog rather than a longshot, especially in a best-of-three where one strong draft or early objective swing can flip the series outcome.[14][1][5]

For traders comparing venues, Polymarket typically shows the market in **implied probability** terms, while Betfair and Smarkets usually make the same opinion more readable as **decimal odds** plus exchange commission, so a sub-50% view can look materially different once fees are included. On exchanges, the relevant question is not just who is likelier to win, but whether the price already discounts the side most recent head-to-head result and current momentum; Dplus KIA’s comeback win in the most recent meeting is a real catalyst, but it is already visible in the tape.[15][9][1] The practical watch-points are the final official match start time, any schedule reshuffle around the LCK broadcast slot, and confirmation that the BO3 is actually played to completion, since cancellation, a delayed start beyond the settlement threshold, or an unfinished series would change the market into the fallback outcome rather than a straight team win.
