LoL: Shark Attack vs SU Esports (BO3) - TCL Play-Ins

Platform comparison

Market context

Shark Attack and SU Esports will meet in the second round of the Turkish League of Legends Championship's Play-Ins bracket on 12 August, competing in a best-of-three series. The winner advances further into the tournament structure; the loser's path depends on the bracket design. A YES share represents confidence that Shark Attack will win the match; a NO share bets on SU Esports victory. The current 20% implied probability for Shark Attack suggests the market views them as significant underdogs.

Turkish League of Legends competition has historically favoured established organisations with consistent roster stability and scrim access. SU Esports' positioning as the implied favourite aligns with typical patterns where teams with stronger regional seeding or prior tournament performances command higher win probabilities in play-in stages. However, play-in rounds frequently produce upsets when underdog teams execute focused strategies or exploit meta-specific champion pools their opponents haven't prepared for. Historical TCL data shows that a 20% probability for the lower-seeded team reflects genuine competitive uncertainty rather than elimination-level disparity.

Traders should monitor roster confirmations and any last-minute substitutions announced before the 10:30 AM ET start time, as mid-tournament line-up changes have occasionally shifted competitive balance in regional leagues. Scrim results, if leaked through community channels, occasionally surface in the 48 hours preceding matches and can shift market sentiment. The settlement window closes at 20:30 UTC on 12 August, allowing approximately 10 hours after the scheduled start for match completion; any delay beyond 7 days without resolution triggers a 50-50 settlement. Stream availability through official TCL channels will confirm match status in real time.

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.
