Market context

G2 Esports and Movistar KOI will contest the League of Legends Championship Series upper bracket final on 25 May, with the winner advancing directly to the grand final. The Polymarket contract currently prices G2's victory at 51%, reflecting near-parity between two of Europe's strongest rosters. Settlement hinges on match completion by 21:00 UTC; any cancellation, tie, or unresolved delay beyond seven days triggers a 50-50 split of the conditional token pool across USDC on Polygon.

Historically, G2 has dominated LEC regular seasons but faced inconsistency in playoffs, whilst Movistar KOI emerged as a challenger franchise with a rising trajectory. The 51% pricing suggests traders view this as a genuine toss-up rather than a G2 coronation. Previous LEC upper bracket finals have often favoured teams with stronger mid-game macro and teamfighting cohesion over raw mechanical skill, a dynamic that shapes how experienced Polymarket participants assess roster matchups.

Traders should monitor roster health and scrim reports in the week preceding the match, though public information remains limited. The LEC typically publishes official schedules and any postponements through its broadcast channels; material delays would be announced well before the settlement window closes. Team composition changes or unexpected player absences could shift the conditional token distribution significantly, though such announcements are rare at this stage of playoffs. The match's position as an upper bracket final—with the loser dropping to a lower bracket semifinal—adds urgency to both teams' preparation.

Methodology

We track LoL: G2 Esports vs Movistar KOI (BO5) - LEC 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.
