LoL: Gen.G vs T1 (BO1) - KeSPA Cup Group Stage

Platform comparison

Market context

Gen.G and T1 face off in a KeSPA Cup group-stage match scheduled for 21 July at 3:30AM ET. The 0% implied probability reflects the market's current state rather than any substantive shift in the past 48 hours; this appears to be an early-stage market with minimal trading activity. Settlement hinges on match completion by 28 July; any cancellation, tie, or seven-day delay without resolution triggers a 50-50 split.

Historically, both organisations have fielded competitive rosters in domestic Korean competition. T1 won the 2023 LCK Summer split and remains a consistent playoff contender, whilst Gen.G secured the 2023 LCK Spring title and has maintained top-four finishes. Head-to-head records in regular season play have been relatively balanced over recent years, though T1's recent international form and roster stability provide marginal structural advantages in single-game formats where preparation depth matters.

The KeSPA Cup operates on a compressed schedule with group stages typically resolved within tight windows. Traders should monitor official LCK announcements for any roster changes, player absences due to injury or military service obligations, or schedule adjustments. Recent patch notes and meta shifts in the weeks leading to 21 July will influence team preparation trajectories. The early-morning ET timing may also affect viewership-dependent market liquidity, though this carries no bearing on match outcome.

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.
