Market context
Team Vitality and Movistar KOI will contest the upper bracket semifinal of the 2026 LEC Playoffs on 23 May, with the winner advancing directly to the final. The match is scheduled for 11:00 AM ET and will be played as a best-of-five series. Current pricing on Polymarket's order book reflects a 42% implied probability for Vitality, suggesting the market views KOI as slight favourites heading into the fixture.
Vitality's playoff performance this season provides the primary historical anchor for assessing this matchup. The organisation has historically performed well in knockout stages when roster cohesion is established, though their regular season standing relative to KOI's will determine baseline expectations. KOI, as a newer competitive entity in the LEC, has demonstrated upward trajectory in recent splits. The 42% probability suggests traders are pricing in KOI's recent form and momentum whilst acknowledging Vitality's experience in high-stakes matches.
Traders should monitor roster announcements or last-minute substitutions before the 23 May fixture, as player availability directly impacts series outcomes in best-of-five formats. Scrim results and team statements in the days preceding the match often signal confidence levels, though these remain unreliable predictors. The settlement window closes at 21:00 UTC on match day, allowing approximately ten hours for the series to conclude. Any technical delays or cancellations beyond seven days would trigger the 50-50 resolution clause, creating tail-risk considerations for positions held close to the deadline.

How active is this market?

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
