LoL: Vivo Keyd Stars vs Fluxo W7M (BO3) - CBLOL Regular Season

Platform comparison

Market context

Vivo Keyd Stars meet Fluxo W7M in a CBLOL regular-season best-of-three, and the crowd price of **0% YES** on this contract is far below both sportsbook-style pricing and trader consensus elsewhere. Polymarket’s own esports page described Vivo Keyd Stars as a slight frontrunner, citing stronger rankings and a prior 2-0 head-to-head sweep earlier in 2026, while Kalshi showed the market much closer to a coin flip, with Vivo Keyd Stars at 49% and Fluxo W7M at 51%.[12][18] That gap matters because the historical comparison is not one of two evenly matched rosters: Vivo Keyd Stars had already beaten Fluxo W7M 2-0 in April and also won their earlier 2026 meeting, giving them the clearer direct matchup edge.[1][14]

For traders, the main catalysts are straightforward: confirmed line-ups, any last-minute schedule changes, and whether the match actually starts before the settlement window closes. Bo3 preview markets on third-party esports sites also leaned towards Vivo Keyd Stars, with implied match prices around 1.19 on one comparison page and around 61% pre-match win probability on another, which is much firmer than the 0% implied by this crowd snapshot.[13][14] If the series is delayed, shortened, or not completed, the contract’s resolution rules become more important than the in-game favourite, because cancellation or an unresolved delay pushes settlement to 50-50 rather than a side win.
