LoL: RMD Gaming vs Vivo Keyd Stars Academy (BO1) - Circuito Desafiante Regular Season

Platform comparison

Market context

RMD Gaming’s Bo1 against Vivo Keyd Stars Academy in Circuito Desafiante has already been played, and the result available in match trackers shows Vivo Keyd Stars Academy won 1-0 on 22 July 2026. That makes the crowd-implied **0% YES** price look consistent with the post-result reality rather than a live pre-match view.[1]

On comparable pricing, external odds screens had Vivo Keyd Stars Academy as a clear favourite at around **1.31 decimal** versus RMD Gaming near **3.01–3.38**, which implies roughly **76%** to **31%** before bookmaker margin rather than a straight 50-50 split.[3][4] For market comparison, Polymarket-style display uses *implied probability* while Betfair and Smarkets are typically read through *decimal odds* and exchange commission, so a 0% crowd price would only diverge from those books if the match were still unresolved; here, the settled match outcome removes that ambiguity.[1][3][4]

For traders, the key catalyst is whether the event was officially completed within the settlement window, because the contract only goes 50-50 if it is cancelled, tied, or delayed beyond seven days without a winner. In this case, the match was listed as finished with a winner, so the practical checkpoint is confirmation from the event page and any league schedule updates, not team news or line-up changes.[1]
