The World Cup didn't just take over your TV.
It took over Wall Street's weirdest cousin: prediction markets.
And the numbers are absolutely bonkers.
In June alone, Kalshi and Polymarket combined pulled in $44.8 billion in trading volume.
That's a 75% jump from May.
One month. One tournament. One giant vibe shift.
Here's how the split looks 👇
Polymarket had been bleeding volume from March through May.
Then the World Cup kicked off on June 11.
And the bleeding stopped. Instantly.
Kalshi's single "Who wins the World Cup?" market has soaked up over $832 million in bets.
35% of the money is riding on France.
Polymarket's tournament winner pool? Around $2 billion on its own.
Even individual match contracts are pulling $500K to $2M each.
Trading peaked near $297 million in a single day on June 24.
Every kick. Every VAR call. Every injury minute.
Someone, somewhere, is trading it.
Prediction markets used to be a niche playground for election junkies and crypto degens.
Now they're eating sportsbooks alive.
No bookmaker. No house edge. Just people trading probabilities like stocks.
And once fans taste that — going back to traditional odds feels ancient.
More than a dozen U.S. states have come swinging.
The accusation: these platforms are running unlicensed sports betting dressed up as "event contracts."
Kalshi and Polymarket disagree — loudly.
Their argument: they're federally regulated by the CFTC, which trumps state gambling law.
It's a real-time legal knife fight.
And $45 billion a month is now on the table.
The World Cup ends July 19.
What happens to volumes after that is the real test.
Because if prediction markets can hold even half of this energy post-tournament…
They won't just be the future of betting.
They'll be the future of every market where opinions have a price.
That's all for now!
