Market context

The League of Legends Upper Bracket Semifinal 2 between LOS and Vivo Keyd Stars will determine one of the final spots in the Esports World Cup South America & LATAM Qualifier Playoffs. The best-of-three match is scheduled for 8 June at 3:15PM ET. In prediction markets, a YES share represents a bet that LOS will win; a NO share bets on Vivo Keyd Stars. The current 0% implied probability for LOS suggests the market has assigned near-zero chance to their victory, though such extreme readings often reflect low trading volume or a decisive historical record rather than certainty.

Vivo Keyd Stars have established themselves as the stronger regional force in recent LATAM League of Legends competition, consistently advancing through playoff stages and maintaining roster stability. LOS, by contrast, has faced roster turnover and inconsistent regular-season performance. Historical matchups between top-seeded and lower-seeded teams in LATAM qualifiers show that upsets remain rare but possible, particularly when preparation time or meta shifts favour the underdog. The 0% probability reflects market consensus that Vivo Keyd Stars are heavily favoured.

Traders should monitor roster announcements or last-minute substitutions in the days before 8 June, as player absences or illness have occasionally altered playoff outcomes in regional tournaments. Schedule confirmation from Riot Games' official channels is essential, given that technical issues or venue problems have occasionally delayed LATAM matches. The settlement window closes 9 June at 01:15 UTC, allowing a seven-day buffer for rescheduling before the market resolves to 50-50 if no result is determined.

Methodology

We track LoL: LOS 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.

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.
