LoL: Maryville University vs Dorado Gaming (BO3) - North American Challengers League Group Stage

Platform comparison

Market context

Maryville University defeated Dorado Gaming 2–0 in their North American Challengers League Group Stage match, a result that occurred on 8 April 2026, not the initially scheduled 16 July date. The match was completed in a BO3 format, with Maryville securing a clean sweep after 3 hours and 50 minutes of play[3][5]. This outcome renders the current 0% YES probability on Polymarket for a Maryville win factually inconsistent with the settled result, suggesting either a platform error or a mismatched event listing.

Historically, similar discrepancies arise when prediction markets fail to update after matches conclude off-platform, particularly in collegiate esports where scheduling shifts are common. On Kalshi, such events typically resolve within 24 hours of official confirmation, whereas Polymarket often retains stale probabilities until manual intervention occurs. Betfair and Smarkets, by contrast, adjust odds dynamically using decimal formats rather than implied probabilities, allowing traders to spot mispricings faster. The fee structures also diverge: Polymarket charges no trading fees but imposes higher withdrawal costs, while Kalshi requires KYC and applies a 1% fee on winnings.

Traders should monitor official NA Challengers League announcements for rescheduling notices or cancellation clauses, as delays beyond seven days trigger a 50–50 settlement. Recent coverage from Sheep Esports confirms the 2–0 scoreline and validates the April date, indicating the July listing may be a duplicate or erroneous entry[2]. Watch for updates from the league’s official channel or team socials, as unresolved listings can persist on unregulated platforms longer than on KYC-compliant books.
