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

Platform comparison

Market context

Team Secret and Karmine Corp are set to face off in the League of Legends Lower Bracket semifinal at the Esports World Cup Group B, with the match scheduled for 9:40AM ET on 15 July. The crowd-implied probability of Team Secret winning sits at 0% YES, suggesting near-universal confidence in Karmine Corp’s superiority ahead of this BO3 clash.

Historically, in Esports World Cup Group stages, European teams like Karmine Corp have dominated lower-bracket matchups against MENA or SEA representatives such as Team Secret, particularly when the latter enter without recent top-tier tournament wins. In comparable BO3 lower-bracket semis from 2024–2025, teams with a 0% crowd probability rarely overturned the odds unless a key roster change or in-game ban disrupted form—none of which have been reported here.

Traders should monitor the official Esports World Cup schedule for any delay notices, as matches postponed beyond seven days trigger a 50-50 resolution. Additionally, watch for pre-match roster confirmations on the tournament’s Discord or official site; a missing player or substitution could shift the probability materially. As of 14 July, no such changes were announced, and Karmine Corp’s recent LFL performance reinforces their dominance [1]. Programmatic traders may condition orders on live odds shifts within the first 10 minutes of the match, where early game outcomes often dictate the full BO3 result.

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.
