Prediction markets took $50B on the World Cup. Your licence is the edge they cannot buy.

Prediction-market sites took more than $50B in bets across the World Cup opening. Kalshi handled $31B in June, about 85% on sports.
Polymarket’s international site set a record $10.8B, plus $3.5B on its US site. The World Cup Winner market alone drew about $3.9B on Polymarket and $800M+ on Kalshi.
Both are regulated by the CFTC and legal in all 50 states on paper. Massachusetts bans sports event contracts, and Arizona, Michigan, Nevada and California are fighting them in court.
Volume this big settles the demand question and opens a sharper one.
These sites are winning on ease and price while carrying none of the player protection that licensed sportsbooks spent a decade building. The sportsbooks hold the one thing the exchanges cannot buy quickly: trust with regulators and players. Right now they treat it as a cost.
Whoever names that difference for the customer keeps the premium.
Expect the first sportsbook to sell its player protection as a reason to pick it rather than a rule it has to follow.
The court fights in five states keep the law unsettled through 2027. A fight like that is won by whoever tells the story first.
