Platform comparison

Active sub-markets

Market context

Karmine Corp face GIANTX in a League of Legends lower bracket semifinal within the LEC Playoffs structure, with the winner advancing and the loser eliminated from the 2026 season. The best-of-five match is scheduled for 1 June at 11:00 AM ET, with settlement closing at 21:00 UTC that day. Current implied probability across platforms sits at 45% for a Karmine Corp victory, suggesting modest favouring of GIANTX, though this reflects fragmentation across venues: Polymarket's decimal odds display (approximately 2.22 for Karmine Corp) differs materially in user interface from Kalshi's implied probability format, whilst Betfair and Smarkets present fractional odds alongside percentage conversions, each affecting how traders perceive the same underlying probability.

Historical LEC lower bracket performance shows teams entering from the upper bracket typically carry momentum advantages, though seeding alone does not determine outcomes in best-of-five formats where individual player form and meta adaptation prove decisive. Recent roster changes and scrim results remain opaque to public markets, limiting the precision of probability calibration. Traders should monitor official LEC announcements regarding any schedule shifts, player availability, or technical issues that could trigger the 7-day delay clause leading to 50-50 resolution. Fee structures diverge meaningfully here: Polymarket charges 2% on both sides, Kalshi typically 1%, and Betfair's commission scales with volume, creating arbitrage opportunities for cross-platform traders if probabilities drift beyond these cost differentials.
