Prediction markets hit record $113.8B Q2 volume as crypto markets cooled
Prediction markets reached a record $113.8 billion in notional volume in the second quarter of 2026, according to CoinGecko data published July 16. The milestone came as spot centralized exchange trading, derivatives volume, and stablecoin market cap all declined during the same period. Polymarket's World Cup winner market alone attracted more than $3.3 billion in trading volume. The data also showed continued interest in contracts tied to the 2028 US election.
The $113.8 billion figure rewrites what regulators and institutional desks consider normal for event-contract markets. For Polymarket and Kalshi, a quarterly record that outruns a declining crypto sector proves prediction markets have decoupled from digital-asset beta and stand as their own asset class. That matters for the CFTC, which must now size these markets for systemic-risk review rather than treating them as a crypto sideshow.
It matters for market makers already committed to both platforms, since sustained volume justifies expanded quoting and tighter spreads. The World Cup's $3.3 billion single-market depth shows sports contracts can absorb institutional size. Election-contract durability through 2028 suggests political markets will not collapse in off-years. Platforms that can replicate this depth across verticals will capture the institutional capital now rotating out of crypto. Those that cannot will shrink to seasonal novelty status.
The $113.8 billion quarter caps a three-cluster run in which prediction markets first cleared $45 billion in a single month, then $50 billion around the World Cup final, and now more than double that in a full quarter, with Polymarket's World Cup winner market alone pulling $3.3 billion.
