LoL: Team Solid vs RMD Gaming (BO1) - Circuito Desafiante Regular Season

Platform comparison

Market context

Team Solid faces RMD Gaming in a single-game League of Legends match for the Circuito Desafiante Regular Season, originally set for 7:00PM ET on 20 July. The market currently shows a 100% implied probability for Team Solid, suggesting the crowd views an RMD win as virtually impossible or the match as already concluded in Team Solid’s favour.

Historically, 100% implied probabilities in esports prediction markets often signal a cancelled fixture, a pre-match forfeit, or a completed result rather than a live competitive edge. On platforms like Kalshi, such extremes are rare due to regulatory caps and KYC requirements, whereas Polymarket’s permissionless structure frequently hosts near-certainty odds on asymmetric matchups. Fee structures diverge sharply here: Smarkets and Betfair charge commission on winnings, while Polymarket embeds fees in the spread, making a 100% line economically distinct across books.

Traders should monitor official Circuito Desafiante announcements for match completion status, as a cancellation or delay beyond seven days triggers a 50-50 settlement. With the settlement window closing on 21 July at 04:30 UTC, any post-schedule update from the league’s broadcast team or Discord channel could invalidate the current pricing. No recent news source confirms a forfeit, but the timing gap between the scheduled start and today’s UTC date suggests the event may have already resolved off-chain.
