LoL: Team Secret Whales vs CTBC Flying Oyster (BO5) - LCP Group Stage

Platform comparison

Market context

CTBC Flying Oyster face Team Secret Whales in an LCP Group Stage best-of-five, and the contract is currently pricing an almost complete CFO sweep on the crowd side. That 100% YES reading is far more extreme than the cross-market signals: Strafe’s match page shows CFO as a sizeable but not overwhelming favourite at roughly 67%, while the league table has CFO top of the group at 3-0 and TSW second at 2-1.[3][10]

History points in the same direction, but not to certainty. CFO beat Secret Whales 2-0 in their February meeting, while Secret Whales later upset them 2-1 in May, so the head-to-head has already swung once this year.[2][11] Broader season records and rankings still lean CFO: Strafe lists CFO at #7 and Secret Whales at #169, and review sites also describe CFO as the stronger side overall.[3][12] That makes a CFO win the analyst-consensus read, but not one that naturally maps to a literal 100% market price.

For traders, the main catalysts are match confirmation, start-time slippage and any format or schedule changes around the LCP stage. The market resolves 50-50 if the series is not played, ends tied, or is delayed more than seven days beyond the scheduled date, so any broadcast notice or official postponement matters as much as the line itself.[9] The listed start times also vary slightly across sources, which is a reminder to watch the official LCP and stream listings rather than relying on a single third-party schedule.[3][10]
