As apostas milionárias que venceram e perderam na Copa do Mundo até agora

Prediction markets experienced unprecedented activity during the World Cup, with high-stakes wagers generating both substantial gains and notable losses. Belgium-related bets and Czech Republic outcomes drove significant volatility, with one bettor losing US$9 million on a single Belgium prediction. The scale of these events underscores growing mainstream adoption of prediction markets for major sporting events.

Polymarket and Kalshi, two leading platforms in the space, both reported record trading volumes tied to World Cup activity. The CEO of Kalshi publicly confirmed that the tournament served as a major catalyst for platform growth, reflecting broader appetite for event-based wagering beyond traditional sportsbooks.

These developments highlight how prediction markets are evolving as alternatives to conventional betting channels, attracting both casual and sophisticated bettors. The concentration of large wagers on single outcomes also raises questions about market efficiency and risk management practices on these platforms. As prediction markets mature, regulatory scrutiny and operational safeguards will likely intensify.
