Gaming Edge’s TL;DR
- The World Cup is doing more than drawing TV audiences – it is driving record activity on prediction market platforms.
- June trading surged on Kalshi and Polymarket, a sign that event-based trading is attracting major attention from US users during one of the biggest sports moments on the calendar.
The 2026 FIFA World Cup helped push prediction market volume sharply higher in June, according to figures cited from Dune Analytics.
Kalshi processed more than $30 billion in trading volume during the month. That was up more than 70% from nearly $18 billion in May. Since the World Cup began on June 11, Kalshi also averaged more than $1 billion in daily trading.
Polymarket reported $10.8 billion in June trading volume, adding to the picture of broad demand across major event-trading platforms.
Interest was especially strong around the US’ tournament chances. Ahead of Monday night’s match against Belgium, more than $64 million had been traded on Kalshi on whether the US will win the World Cup. On Polymarket, that same question had drawn $122 million in trading.
Unfortunately, the Team USA lost 4-1 to Belgium and is out of the tournament. It remains to be seen how that will impact World Cup betting in the US going forward.
World Cup a demand accelerator for trading
It highlights how prediction markets are increasingly intersecting with the same audience that follows sports betting and other online wagering products in the US.
The biggest takeaway is scale. A single global tournament helped generate tens of billions of dollars in monthly activity across two well-known platforms. That suggests major sporting events can act as demand accelerators for event-based trading, especially when Team USA is involved.
Kalshi and Polymarket saw heavy action tied to a headline event, and the US angle was clear in the volume centered on whether the American team could win the tournament.
CNN has a partnership with Kalshi and uses its data to cover major events. CNN said its editorial employees are prohibited from participating in prediction markets.
