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 powerhouse Karmine Corp against American squad Sentinels in a League of Legends best-of-three, scheduled for 7:20 AM ET on 16 July. With the crowd-implied probability at 100 % for Karmine Corp, the market treats a French victory as virtually certain, leaving no room for a Sentinels upset under normal conditions.

Historical precedents in LoL group-stage knockouts show that 100 % implied probabilities rarely survive once live play begins, especially when cross-regional matchups involve strong North American teams like Sentinels. In past Esports World Cup editions, teams with similar pre-match certainty have occasionally lost due to map-specific weaknesses or early-game errors, suggesting the current pricing may overstate Karmine Corp’s dominance despite their recent Valorant playoff predictions favouring them against other opponents[1].

Traders should monitor the official Esports World Cup schedule for any delay notices beyond the seven-day resolution window, as well as pre-match roster announcements that could alter team strength. A cancellation or tie would trigger a 50–50 settlement, while a match that starts but remains incomplete still resolves to the winner if one is declared. On Polymarket, this 100 % probability translates to decimal odds of 1.00 with no fee on wins, whereas Kalshi and Betfair would express this as 1.00 decimal odds but apply different fee structures and KYC thresholds, creating divergent liquidity and execution costs for the same event.
