Prediction markets topped $50 billion in monthly volume in June, driven by trading on the FIFA World Cup 2026, CoinDesk reported Tuesday.
Kalshi posted $31 billion in notional volume, more than 70% higher than the prior month. Polymarket's international exchange logged $10.8 billion, a new monthly record. Polymarket's regulated U.S. platform added $3.5 billion, nearly double May's total. Rothera, a joint venture between Robinhood and Susquehanna International Group, processed $2 billion in its first month of operation after launching in June, the report said, citing Dune data.
World Cup-related contracts accounted for $7.4 billion of Kalshi's June volume alone. Both Kalshi and Polymarket advertised heavily during the games, according to the report.
Kalshi announced June 26 that it formed a branding and product partnership with ADI Predictstreet, the official prediction market partner of the FIFA World Cup 2026. In the first two weeks of World Cup play, Kalshi said its platform saw "explosive growth" and recorded daily volume above $1 billion.
"The World Cup is the largest stage for any brand," Kalshi Co-Founder and CEO Tarek Mansour said in a press release. "We see this as a massive opportunity to increase global awareness and fan engagement."
Wall Street broker Bernstein said in April it expects prediction market volumes to hit $1 trillion by 2030 as the industry moves from niche bets to a broader "information market" covering sports, cryptocurrency, politics and the economy. Prediction markets reached $51 billion in volume last year and are on track for roughly $240 billion this year, the report said.
