Counter-Strike: Sharks vs ECHO (BO3) - Super DraculaN Playoffs

Platform comparison

Market context

The underlying event is the Best-of-3 Counter-Strike 2 third-place decider between Sharks Esports and Echo, held at the Bucharest LAN on 28 June 2026. Echo secured a 1–2 victory, winning Inferno 13–9, Nuke 16–13, and Ancient 13–8, while Sharks had been the bookmaker favourite and ranked higher globally prior to the match[1][2].

Historically, third-place deciders in CS2 LANs often defy pre-match form when one team adapts better to specific map picks; Echo’s reversal of the 88.9% pre-match vote share for Sharks mirrors similar upsets in 2024 where lower-ranked teams capitalised on underprepared map strategies[1][4]. The current 0% prediction-market implied probability for Sharks reflects this settled outcome, diverging sharply from the pre-match sportsbook lines that favoured Sharks by 15–20%[4][5].

Traders should monitor post-match analyst reports confirming whether the result was due to tactical errors or roster instability, as well as any official statements on future roster changes for either team[2]. Recent coverage from Strafe confirms the final score and map breakdown, providing the definitive settlement data needed to validate the contract’s resolution[1]. No further announcements are expected before the settlement window closes on 28 June 2026 at 19:30 UTC.

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.
