Market context
Maryville University and Conviction were scheduled to meet in an upper-bracket quarter-final of the North American Challengers League playoffs in a best-of-three League of Legends series. The current 0% yes price implies the market is effectively not assigning any chance that Maryville are confirmed as the winner before settlement; in practice, that should be read alongside the event state, not as a performance forecast. Comparable NACL head-to-heads have often moved sharply once a series is officially listed, postponed, or completed, especially when a market can still resolve 50-50 if no winner is determined within the delay window. For UK-facing users, the same activity can sit uneasily with Germany’s GlüStV framework if offered there, while US CFTC reach remains relevant where a venue is viewed as a derivatives-like venue. “No-KYC up to $1,500” typically means lower-value access can be available without full identity verification, but it does not remove platform geoblocking, sanctions checks, or withdrawal controls.
The key catalysts are whether the match is actually played, rescheduled, or already completed elsewhere, because that determines whether the market resolves to one side or to 50-50 under the no-result clause. The relevant operational checks are the tournament schedule, official NACL playoff updates, and any VOD or scoreboard confirmation from trusted esports databases such as Liquipedia or Sofascore; those sources already show the matchup and timing history, but not necessarily the final settlement outcome. Traders should also watch for bracket changes or broadcaster announcements, since playoff delays can trigger the seven-day clock. If the series is still unplayed after the scheduled date, the resolution mechanics matter as much as the game result.
Methodology
We track LoL: Maryville University vs Conviction (BO3) - North American Challengers League Playoffs on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
