Bottom Line
The World Cup turned prediction markets from "politics + macro" tools into mainstream sports gambling rails. Kalshi and CEXs captured most of the $5.6B wave thanks to easy onboarding. But with rapid growth comes scrutiny on fairness and rules. If $10B is hit, this could be the breakout moment for prediction platforms.
