Prediction markets top $50 billion in June trades on World Cup volume
Prediction markets generated over $50 billion in trading volume during June, fueled by World Cup event contracts. The figure spans activity across platforms including Kalshi and Polymarket, as well as smaller venues.
Why this matters?
The $54 billion monthly figure demonstrates that major sporting events can drive prediction-market volume at a scale comparable to traditional derivatives markets, validating the sector's liquidity thesis for global event contracts.
The bigger picture
Record monthly volume headlines this month across Kalshi, Polymarket, and smaller platforms, giving Congress unified data to cite as it weighs a bipartisan Senate ban on CFTC-registered sports event contracts.
