Counter-Strike: Infinite vs 100 Thieves (BO3) - Esports World Cup Open Qualifier Play-Ins

Platform comparison

Market context

The match between Infinite and 100 Thieves in the Esports World Cup Open Qualifier Play-Ins is a best-of-three Round of 32 tie, with the sportsbook market broadly treating 100 Thieves as the stronger side. Betsafe lists 100 Thieves at 1.17 and Infinite at 4.40 in outright terms, which implies a far larger gap than the prediction market’s 27% YES price for Infinite and points to a material spread between exchange-style pricing and bookmaker shading.[11][6]

That gap is easier to read in context. The qualifier itself is a short, high-variance B-tier event running across 9 August, with 32 teams competing for a place in the main Esports World Cup CS2 event and a share of the $100,000 prize pool.[2][5] Comparable pricing elsewhere is also lopsided towards 100 Thieves: Bitget Wallet shows roughly 78% for 100 Thieves versus 23% for Infinite, while Predict.fun had a recent snapshot closer to 51% on 100 Thieves and 49% on Infinite, underscoring that the market can move quickly when the bracket and line-up news is thin.[7][13]

For traders, the main catalysts are schedule confirmation, roster finality and whether the match starts on time. Live listings from Bo3.gg and Sport.ru place the game at 09:00 UTC / 5:00 AM ET, and a delay beyond seven days or a cancellation would force a 50-50 settlement under the contract rules.[4][9] The most relevant external form reference is 100 Thieves’ recent upset of Team Falcons in BLAST Bounty Summer 2026, which supports the view that the team may be more competitive than a simple underdog label suggests, even if the current market still favours them strongly.[14]

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.
