Market context

LOUD and Vivo Keyd Stars face off in an Upper Bracket Quarterfinal of the Esports World Cup South America & LATAM Qualifier Playoffs on 7 June at 12:00 PM ET, with the winner advancing deeper into the tournament structure. The 0% YES probability on Polymarket reflects near-total market confidence in LOUD's victory, with conditional tokens priced to reflect minimal uncertainty around a Vivo Keyd Stars upset. On Polygon, USDC liquidity pools currently price the match as a heavily favoured outcome for the Brazilian organisation.

LOUD has established itself as the dominant force in South American League of Legends, consistently finishing atop regional standings and qualifying for international competition. Vivo Keyd Stars, whilst a competitive regional side, has not demonstrated the same level of consistency or tournament pedigree. Historical matchups between these organisations and their respective performances in qualifying rounds inform the market's extreme skew. Recent tournaments show LOUD winning similar high-stakes fixtures with relative comfort, establishing the baseline from which traders assess deviation risk.

The settlement window closes 7 June at 22:00 UTC, allowing six hours post-match for official results confirmation. Traders should monitor for schedule changes, technical issues affecting broadcast integrity, or unexpected roster alterations announced before match start. The conditional token structure means any delay exceeding seven days without resolution triggers a 50-50 split, creating a secondary risk vector independent of in-game performance.

Methodology

We track LoL: LOUD vs Vivo Keyd Stars (BO3) - Esports World Cup South America & LATAM Qualifier Playoffs on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
