Prediction market operator Kalshi recorded 15.4 million U.S. website visits in July 2026, an increase of roughly 1,520% from fewer than 1 million visits in August 2025, according to Similarweb data.
U.S. users accounted for nearly 80% of Kalshi's total traffic, up from 72.8% a year earlier.
Kalshi's trading activity has also accelerated sharply. Monthly trading volume reached approximately $40 billion in August 2026, up roughly 4,500% from $874 million a year earlier. The company's valuation has also reportedly climbed to $40 billion, leveraging its compliance-first approach over competitors. Kalshi operates as a U.S.-regulated exchange, having been approved by the Commodity Futures Trading Commission (CFTC), a designation that has distinguished it from offshore rivals in the fast-growing prediction markets sector.
The growth reflects a broader shift in which event contracts—letting users trade on outcomes ranging from elections to sports results—have moved from a niche corner of derivatives trading into mainstream retail activity. Across the broader prediction markets industry, monthly notional volume rose to $50.7 billion from about $2 billion year over year. Kalshi accounted for roughly 80% of that total, with sports contracts making up 83% of Kalshi's trading volume in July 2026, underscoring how sports, rather than politics or economics, has become the primary driver of trading activity.
Traffic growth was also notable outside the United States:
- Canada generated approximately 450,000 visits in July 2026, up from roughly 50,000 a year earlier.
- U.K. traffic reached approximately 300,000 visits, up from 31,000.
The surge comes as Kalshi faces mounting legal challenges over whether its sports contracts should be regulated by the federal CFTC or under state gambling laws. A recent court ruling saw the platform lose its bid to stop state-level gambling enforcement, handing regulatory power to the states. The outcome of that regulatory dispute is likely to shape how the industry's largest operator structures its sports offerings going forward, and whether the sector's rapid expansion continues at its current pace.
