Counter-Strike: Sashi Esport vs BIG (BO3) - Esports World Cup Open Qualifier Play-Ins

Platform comparison

Market context

Sashi Esport’s quarter-final Bo3 with BIG in the Esports World Cup Open Qualifier Play-Ins has already played out, with BIG winning 2-1 in Paris at 15:10 UTC, so the contract’s 0% yes price is consistent with a completed loss for Sashi rather than a live coin-flip. Sofascore lists the match as finished 1-2, while tournament schedules place the fixture inside the Play-Ins bracket on 9 August, which is the key date traders use for settlement timing.[2][3]

The clearest historical frame is that Sashi had been treated as a live underdog only when compared with broader qualifier opponents, not with BIG specifically. Recent market activity on the same event showed heavy trading in adjacent Big-vs-Sashi derivatives, and Polymarket’s esports board also carried a separate Sashi market at roughly two-thirds implied support against a different opponent, which underlines how matchup-specific these prices are.[1][12] In head-to-head terms, Sashi had one recorded win over BIG before this event, but BIG also had previous victories, so the match-up was not one-sided on paper.[5]

For traders, the main catalysts were the official bracket order, match start confirmation, and whether the Bo3 completed before the seven-day settlement clock mattered. The available live schedules showed the Play-Ins running on 9 August in France, and multiple scoreboards updated the match state in real time once it began.[2][3][6] Since the result is already final, the only remaining market-sensitive issue is whether the contract’s reporting source recognises the completed 2-1 score as definitive, which would leave little room for divergence between sportsbook-style match lines and prediction-market settlement.[1][2]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
