Platform comparison

Active sub-markets

Market context

The underlying event is a Counter-Strike 2 match between ex-Sashi Academy and eternal premium in the European Pro League Series 8 Closed Qualifier, originally set for 6:30 AM ET on 25 June. The match has already concluded, with ex-Sashi Academy securing a 2-1 victory after a tight three-map contest, scoring 13-10, 10-16, and 19-13 across the maps[1]. This result directly contradicts the current 10% crowd-implied probability for ex-Sashi Academy winning, suggesting a significant lag in market settlement or a mispricing anomaly that traders must address immediately.

Historically, prediction markets in CS2 qualifiers often exhibit delayed corrections when matches conclude outside peak trading hours, particularly in early morning ET slots where liquidity thins. Comparable cases from the 2025 European Pro League show similar 15–20% probability divergences resolving within 48 hours post-match, driven by analyst consensus confirming the outcome[1]. The current 10% line for ex-Sashi Academy, despite their confirmed win, mirrors these past inefficiencies, indicating the market has not yet fully incorporated the final score into its pricing framework.

Traders should monitor official settlement announcements from the platform and cross-reference with real-time odds on Kalshi and Sofascore, where the result is already marked as final[1][2]. No further catalysts are pending, as the match outcome is definitive; the only dependency is the platform’s administrative update to resolve the contract. Recent coverage on Gosugamers confirms the 2-1 scoreline and ex-Sashi Academy’s victory, leaving no ambiguity for market resolution[3]. The divergence between the live result and the 10% implied probability represents a clear arbitrage opportunity for those acting before the market corrects.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
