Market context

LOUD and Vivo Keyd Stars are scheduled to face off in the Upper Bracket Quarterfinal 3 of the Esports World Cup South America & LATAM Qualifier Playoffs on 7 June at 12:00 PM ET. The match is a best-of-three format, with the winner advancing deeper into the regional qualifier bracket that feeds into the broader Esports World Cup competition. The settlement window closes at 22:00 UTC on the same day, allowing a six-hour buffer beyond the scheduled start time for the match to conclude.

The 0% implied probability reflects LOUD's established dominance in Brazilian League of Legends. LOUD has consistently finished as a top-two seed in regional competitions and maintains a track record of advancing through qualifier stages. Vivo Keyd Stars, whilst a competitive organisation, has historically struggled to overcome LOUD in direct matchups. Prior regional playoff encounters between these teams have typically favoured LOUD by margins suggesting a probability substantially higher than the crowd's current assessment. This divergence between historical performance and current market pricing warrants scrutiny.

Key variables affecting settlement include fixture confirmation and any last-minute roster changes. The Esports World Cup qualifier schedule has experienced occasional delays in previous seasons, though typically resolved within the seven-day buffer built into the resolution criteria. Traders should monitor official League of Legends Championship Series announcements for any schedule adjustments or technical issues that might push the match beyond the settlement window. Player availability and team preparation status in the week preceding 7 June will influence match outcome probability.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
