Market context

Team Vitality face Movistar KOI in the LEC upper bracket semifinal on 23 May, with the 9% implied probability reflecting heavy favouritism towards Vitality. The matchup pits the region's most decorated organisation against a KOI side that has shown inconsistency throughout the 2024 regular season. Vitality secured first place in the regular standings and enter playoffs as the tournament favourite, whilst KOI finished fourth and must navigate the upper bracket gauntlet to reach finals.

Historical LEC playoff data shows that regular season seeding carries substantial predictive weight in best-of-five formats. Teams finishing first have won their opening playoff matchups at roughly 75–80% rates over the past three seasons, with the gap widening further when facing fourth-place finishers. Vitality's roster continuity—maintaining their core from 2023—contrasts with KOI's mid-season roster adjustments, a factor that typically correlates with lower playoff performance. The 9% probability assigned to KOI suggests the market views an upset as unlikely but not impossible, pricing in scenarios where KOI's individual mechanical skill overcomes structural disadvantages.

The match settlement window closes 24 May at 21:00 UTC, allowing a full day buffer beyond the scheduled start time. Traders should monitor official LEC communications for any schedule shifts or technical delays that could trigger the 7-day cancellation clause. Recent LEC broadcasts have proceeded without major disruptions, though server issues or player illness remain potential catalysts. KOI's recent scrim performance and any last-minute roster confirmations could shift market sentiment in the 48 hours before play.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
