LoL: CTBC Flying Oyster vs Ground Zero Gaming (BO5) - LCP Group Stage

Platform comparison

Market context

CTBC Flying Oyster and Ground Zero Gaming are scheduled to meet in a best-of-five League of Legends series in the LCP group stage, and this market pays out on the team that wins the match. In prediction markets, a **YES** share means the named outcome happens; here, a YES on CTBC Flying Oyster means CFO wins the series, while a YES on Ground Zero Gaming means GZ does. The current crowd price of 0% YES suggests traders are assigning almost no chance to the listed outcome, but that should be read against the specific contract wording and any late changes to the fixture.

Recent comparable results point to a more competitive baseline than a 0% price implies. Ground Zero beat CTBC Flying Oyster 3-1 in a LCP 2026 playoff meeting, but the teams also split earlier head-to-heads, and one recent LCP regular-season listing showed CTBC Flying Oyster winning 2-0 in February. Standings in LoL Esports also had Ground Zero above CTBC Flying Oyster in the Split 1 regular season, with Ground Zero 4-3 and CFO 3-4, which helps explain why pre-match opinion can swing quickly depending on form and stage context.[1][3][12]

The main things to watch are official start-time changes, roster or substitution announcements, and whether the series is actually played in full before the settlement window closes. The market’s rules matter: if the match is cancelled, ends in a tie, or is delayed by more than seven days without a winner, it resolves 50-50 rather than to either team. That means late schedule shifts, venue issues, or a series interrupted before completion can matter as much as team strength in determining the contract outcome.[3][6]

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.
