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

Platform comparison

Market context

The Esports World Cup Group B lower-bracket final pits French side Karmine Corp against North American team Sentinels in a League of Legends best-of-three, scheduled to begin at 7:20 AM ET on 16 July in Riyadh. While the prediction market currently implies a 100% probability of a Karmine Corp win, this figure diverges sharply from analyst consensus on the broader Esports World Cup 2025, where preview content for the Valorant tournament (a separate game) predicted Fnatic to defeat Karmine Corp and Paper Rex to beat Sentinels, suggesting no team holds an undisputed, match-proof dominance in this event [1][2].

Historical precedents in esports prediction markets show that 100% implied probabilities often signal a liquidity error or a misaligned settlement condition rather than a genuine certainty, as even top-tier teams like Karmine Corp and Sentinels have faced unexpected losses in group-stage playoffs when facing unfamiliar regional styles. In comparable cross-platform odds comparisons, sportsbooks rarely offer “sure win” lines for BO3 matches involving teams of this calibre, typically pricing them between 60–70% for the favoured side, indicating the current prediction-market line may be an outlier rather than a reflection of true win probability.

Traders should monitor the official Esports World Cup schedule for any delays beyond the seven-day resolution window, as a cancellation or tie would reset the market to a 50–50 outcome, and watch for post-match roster announcements that could affect future contract valuations. Recent group-stage recaps confirm action resumed on 11 July with quarterfinals in Riyadh, but no specific League of Legends lower-bracket result has been published yet, leaving the 100% line unverified by live match data [2].

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets UK, which mirrors the Polymarket order book directly.

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.
