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

Platform comparison

Market context

Polymarket has this BO3 priced at **0% YES**, which on the contract means traders currently assign effectively no chance to a **Vivo Keyd Stars** win in the USDC-settled, Polygon-based conditional token market before the settlement window closes. The underlying fixture is the CBLOL Regular Season meeting between Vivo Keyd Stars and Fluxo W7M, with the scheduled start shown by match trackers as 21:00 UTC on 7 August 2026.[1][2]

That pricing sits well outside the historical comparison set. Public match pages show Vivo Keyd Stars with a strong head-to-head edge over Fluxo W7M, including a 2-0 win in their April 2026 meeting and a broader unbeaten run in the series, while pre-match models and bookmaker-style odds on third-party pages still lean towards Vivo Keyd Stars rather than a clean Fluxo upset.[3][12][13][14] In other words, a 0% Polymarket read is not a neutral “pick’em” signal; it implies either stale trading, a market-maker gap, or a very strong view that the eventual contract outcome will not be a straightforward Vivo Keyd Stars win under the market rules.

A trader watching this contract should focus on whether the fixture is actually completed and officially recorded, because Polymarket’s resolution depends on the match outcome, with cancellations, ties, or a delay of more than seven days from the scheduled date pushing settlement to 50-50 instead.[9] The practical catalysts are simple: last-minute schedule changes from CBLOL, server or venue issues, and any broadcast or tournament notice that affects whether the BO3 starts on time or finishes with a decisive winner.[1][18]
