LoL: Fnatic vs Karmine Corp (BO3) - LEC Regular Season

Platform comparison

Market context

Fnatic meet Karmine Corp in a LEC regular-season best-of-three, and the market’s **23%** crowd-implied chance on Fnatic leaves Karmine Corp as the clear favourite in consensus terms. That price is broadly consistent with recent sentiment that has leaned towards KC on current form, while still leaving a meaningful underdog case if Fnatic’s head-to-head edge carries into a longer series.[3][14]

The historical frame is mixed rather than one-way. One recent preview says Fnatic led the last five meetings in 2025 by 3-2, including a 3-1 series and a 2-1 win, and also cites an aggregated matchup split of 75% for Fnatic versus 25% for Karmine Corp.[1] By contrast, market commentary and vote data around spring 2026 pointed to Karmine Corp as the stronger side, with an 81.9% user vote share in one prior meeting and a finished 2-1 KC result in April, which supports the idea that the live consensus has shifted towards KC even if Fnatic still retain upset equity.[14]

For traders, the main catalysts are lineup confirmation, any schedule slippage, and whether both teams arrive with full preparation after the weekend slate. Polymarket’s own event page describes KC as entering with an undefeated 5-0 start and Fnatic as sitting around 5-6 with a two-game losing streak, which is the sort of form gap that can keep the favourite price anchored unless Fnatic news improves sharply.[3] The value angle is therefore more contrarian on Fnatic than on KC: if there is a late read that Fnatic’s drafting or early-game execution matches up well, the 23% line looks more attractive than the market’s broader KC bias, but absent that, consensus remains firmly with the favourite.[1][3]

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.
