Counter-Strike: Isurus vs Yawara Esports (BO3) - CCT South America Series 3 Playoffs

Platform comparison

Market context

The real-world event is a Best of 3 Counter-Strike 2 match between Isurus and Yawara Esports in the CCT South America Series 3 Playoffs, which took place on 7 July 2026 at 13:00 UTC. The match has already concluded with Isurus winning 2–0, confirming the outcome for the prediction market. In prediction markets, a YES share pays out if the specified event occurs (here, Isurus winning), while a NO share pays out if it does not; the current 100% YES crowd-implied probability reflects the certainty of this result after the match finished.

Historically, markets showing 100% probability before a match start are rare and often signal either a known outcome or a severe mispricing, as seen in past esports cases where one team was disqualified or the match was cancelled before play. However, in this instance, the 100% figure is justified post-match, as Isurus’s 2–0 victory is documented across live-score platforms like GosuGamers and Strafe, which recorded the final score and confirmed the winner[1][2]. This aligns with how settled markets resolve: once the event concludes, probabilities converge to 100% for the winning outcome.

Traders should monitor official tournament announcements from CCT and team social channels for any post-match clarifications, though the result is already confirmed. Recent coverage from Strafe noted that pre-match sentiment favoured Yawara Esports with 78% of votes, making Isurus’s win an unexpected but decisive outcome[2]. No further catalysts are needed, as the match is complete and the settlement window will close on 7 July 2026 at 19:00 UTC with Isurus as the resolved winner.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

How does resolution work?

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
