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

Platform comparison

Market context

Polymarket currently prices CTBC Flying Oyster vs GAM Esports at **37% YES**, which means the contract is trading as a clear underdog on the CTBC Flying Oyster side, while the token itself is settled in USDC on Polygon through conditional tokens tied to the official match outcome. The market resolves on the BO3 result, but if the match is not played, ends level, or is pushed beyond the seven-day grace period without a winner, it flips to 50-50 under the contract rules.

The pricing sits against a mixed but informative head-to-head record. Recent listings and match histories show the teams have met repeatedly across the LCP era, with CTBC Flying Oyster holding the stronger overall series record, yet GAM has taken some of the more recent notable meetings, including a 2-1 win in Split 2 and a 2-0 win in their January 2026 regular-season meeting[10][15][16]. That combination usually matters in Polymarket pricing: historical dominance can support the favourite, but recent results and the BO3 format can narrow the gap when the underdog has already shown it can take a series.

For traders, the key catalysts are simple and time-sensitive: the official start time, whether the series goes ahead on schedule, and any late change to match status from the league or broadcast operators. Third-party listings place the match on 31 July at 11:30 UTC, while live score pages are already tracking it as an active fixture, which reduces but does not eliminate rescheduling risk[4][5]. In practice, the contract will mostly move on pre-match information, line-up confirmation, and any delay or cancellation signal, because those are the events that can change the payoff path before the BO3 is decided.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
