In June 2026, the trading volume on the prediction platform Kalshi reached $9.4 billion. This set a new all-time high, confirming the rapid growth of interest in prediction markets.
For comparison, Polymarket's figure for the same period was $4.3 billion, more than half that of the leader. This trend indicates a shift in trader preferences toward Kalshi, which likely benefits from a broader range of events and a user-friendly interface.
Experts attribute the record activity primarily to the 2026 FIFA World Cup, which kicked off on June 11. Massive interest in sports outcomes, as well as related macroeconomic and political events, creates an ideal environment for volume growth on prediction platforms.
Analytical commentary from Cryptalist: Kalshi's record is not just a number, but a clear signal that prediction markets are transitioning from a niche tool to the mainstream. In the coming quarters, we will likely see further consolidation in this sector, especially amid major sports and political events. Polymarket urgently needs to boost liquidity and attract new users to avoid losing market share.
