Polymarket LoL submarkets spike to 90% on three straight days with no volume disclosure
Polymarket's League of Legends submarkets saw sharp probability swings across three consecutive days of LCS and LEC matches. A dragon-kill contract for Fnatic versus Karmine Corp spiked to 90.5%, while odds moved sharply on the Dignitas versus LYON and Cloud9 versus Disguised match outcomes. None of the reports disclosed trading volume or what triggered the moves. Polymarket also listed a new contract for SK Gaming versus Team Vitality in the LEC. The contracts cover niche in-game events with binary resolution windows.
Polymarket's esports submarkets now show a repeat pattern: contracts spike to or near 90% on thin or undisclosed volume, leaving traders unable to judge whether the move reflects genuine information or book drift. Retail participants face slippage that can erase any edge they hold on the match outcome itself.
The platform's CFTC registration does not itself guarantee orderly two-sided flow in these niche events. Institutional market makers observing across verticals will demand proof of genuine depth before committing capital. Kalshi and ForecastEx can cite these episodes when pitching their own gaming contracts as more stable alternatives.
