LoL: Team Secret vs Karmine Corp (BO3) - Esports World Cup Group B

Platform comparison

Market context

Team Secret and Karmine Corp face off in the League of Legends Lower Bracket semifinal at the Esports World Cup Group B, a match originally slated for 9:40 AM ET on 15 July. The crowd-implied probability of Team Secret winning sits at 0%, suggesting the market views Karmine Corp as the overwhelming favourite in this BO3 encounter.

Historically, 0% implied probabilities in live esports prediction markets often signal either a near-certain outcome or a data anomaly where liquidity has not yet corrected for late roster changes or bracket context. In comparable Esports World Cup lower-bracket clashes, teams entering with such lopsided odds have occasionally overturned expectations when the higher-ranked side suffers fatigue from earlier grinds, though such reversals remain rare without visible pre-match indicators. Programmatic traders typically flag these extremes for conditional order triggers, waiting for a shift above 1% before deploying capital.

Key catalysts include official roster confirmations, any delay notices beyond the seven-day settlement window, and the match’s actual start time relative to the scheduled 9:40 AM ET slot. Traders should monitor the Esports World Cup official schedule page and Team Secret’s social channels for last-minute updates, as a cancellation or tie would reset the market to a 50-50 resolution. A recent Esports Insider report on the Esports World Cup noted that lower-bracket matches are prone to scheduling compression, increasing the risk of delays that could impact settlement [1].

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

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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi Fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.
