LoL: Movistar KOI vs GAM Esports (BO3) - Esports World Cup Group C

Platform comparison

Market context

Movistar KOI, the Spanish League of Legends squad, faces GAM Esports from Vietnam in the Esports World Cup Group C lower-bracket semifinal, a match initially slated for 9:40 AM ET on 15 July. The contest is a best-of-three series where a single victory determines the market outcome, with the Spanish side currently favoured by bookmakers offering odds as low as 1.42, implying a win probability near 70% [4].

Historical data from the Group Stage shows Movistar KOI already defeated GAM Esports 1–0 in a 30-minute game, securing a clean ace that highlighted their dominance in that encounter [3]. While GAM holds a 50% overall win rate compared to KOI’s 60%, KOI’s recent form is stronger, winning over 70% of their last matches, which aligns with the 100% YES crowd-implied probability on the prediction market despite the sportsbook line suggesting a less certain outcome [4][6].

Traders should monitor official Esports World Cup schedule updates for any delays beyond the seven-day resolution window, as unplayed or tied matches trigger a 50–50 settlement. No new roster announcements or injury reports have emerged since the Group Stage clash, and the match’s completion depends solely on the tournament’s progression without external dependencies [7]. The divergence between the 100% market probability and the 70% sportsbook implied probability reflects a strong consensus among prediction-market participants that KOI will replicate their earlier Group Stage victory.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
