World Cup Pushes Prediction-Market Volume to Record $50 Billion in June as Kalshi, Polymarket Race Ahead
- Prediction-market platforms collectively topped $50 billion in monthly trading volume for the first time in June 2026, driven primarily by the expanded 48-team FIFA World Cup, CNBC reported (https://www.cnbc.com/2026/07/04/2026-fifa-world-cup-boosts-prediction-market-volumes.html).
- Kalshi led with roughly $33 billion in monthly volume (with $7.4 billion tied to World Cup contracts), while Polymarket handled about $14 billion and new entrant Rothera added $2 billion; the Canada–Morocco Round-of-16 match alone drew over $100 million combined across platforms.
- The volume milestone lands as the CFTC pushes new event-contract rules and several U.S. states continue legal fights to classify the platforms under state gambling laws, framing a live regulatory-vs.-industry-growth fight for finance readers.
