LoL: CTBC Flying Oyster vs GAM Esports (BO3) - LCP Group Stage

Platform comparison

Market context

CTBC Flying Oyster’s meeting with GAM Esports in the LCP group stage is priced at 37% for CFO on the market, which is broadly consistent with a modest underdog rather than a longshot. Recent head-to-head results show the matchup has not been one-sided: GAM won 2-0 in January 2026, while GAM also beat CFO 2-1 in a later 2026 LCP meeting, but CFO took the upper hand in at least one 2025 series and recent community pricing has swung the other way on some platforms, with Strafe users leaning to CFO at about 69% in the same fixture.[2][5][17] On paper, that divergence matters: a Polymarket-style event market expresses the chance directly as a yes/no probability, whereas Betfair- or Smarkets-style books show decimal odds and apply exchange commission, so the same view can look cheaper or pricier depending on the fee and market-making layer.[5]

The main catalysts are simple: confirmed line-ups, whether the match starts on schedule, and any late bracket or broadcast changes before the 17:30 UTC settlement window closes. Flashscore and Sofascore both list the fixture for 31 July, which supports the event being live, but traders still need to watch for official LCP schedule updates because a no-contest, tie, or delay of more than seven days would push the market to 50-50 under the rules.[1][3] On Kalshi, access is restricted by jurisdiction and user verification, while Betfair and Smarkets are exchange models with different fee schedules; that affects how much edge a trader needs versus a platform that settles purely on the binary match winner.[3]
