LoL: Cupid Esports vs Conviction (BO3) - North American Challengers League Playoffs

Platform comparison

Market context

Cupid Esports face Conviction in the North American Challengers League playoffs, with the match listed for 20 August and a best-of-three format. The market is already priced at 100% YES for Cupid, but the cross-platform picture is less extreme: Polymarket showed Cupid around 86% on its main odds page, while sportsbook pricing seen elsewhere sat nearer 1.39–1.50 for Cupid and 2.40–2.60 for Conviction, implying a strong favourite rather than a near-certainty.[1][4][9][14]

That gap matters because NACL playoff markets can move quickly on bracket confirmation, stream schedules and any late rescheduling. Bo3 listings for the same fixture placed the start at 21:00 UTC, and the playoffs were set to run as a double-elimination bracket from 20 August into September, so any delay or venue change could alter settlement risk if the match slips beyond the stated window.[2][3][5]

For comparison, this kind of pricing often sits between model-driven bookmaker lines and thinner prediction-market liquidity, where early crowd consensus can overstate certainty before line-up news or official start confirmation. Here, the main divergence is not on the favourite, but on the margin: analyst-style and bookmaker views point to Cupid, while the contract’s 100% YES implies the market has effectively priced out upset, cancellation, or postponement risk already.[7][8][13][15]

Methodology

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, which mirrors the Polymarket order book directly.

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.
