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

Platform comparison

Market context

Shark Attack and SU Esports will meet in the TCL Play-Ins mid bracket round 2 on 12 August, with the winner advancing further in Turkey's League of Legends regional qualifier. The best-of-three format means first to two victories takes the series. At 22% implied probability on Polymarket, the market prices Shark Attack as a substantial underdog, though the current odds diverge notably across platforms: Kalshi's decimal format (4.55) and Smarkets' fractional representation both reflect similar pricing, whilst Betfair's liquidity on TCL events remains considerably lighter, creating wider spreads on comparable matches.

Historical TCL Play-Ins data shows mid bracket round 2 encounters frequently favour teams with recent LFL or international experience. SU Esports' roster composition and recent scrim results against established regional sides provide context for the crowd's confidence in their victory. Shark Attack's path to this stage suggests they've overcome earlier opposition, though their win rate against comparable-tier competition in qualifying rounds typically sits below 30% when facing teams with SU's tournament pedigree.

Traders should monitor roster confirmations through the TCL's official schedule updates and any last-minute substitutions announced within 24 hours of match start. Recent patch changes to League's meta, released on 8 August, may disproportionately favour one team's champion pool or playstyle. The settlement window closes at 20:30 UTC on match day; delays beyond 7 days trigger the 50-50 resolution clause across all major platforms, though Polymarket's fee structure (2% maker, 2% taker) remains consistent regardless of outcome timing.
