Odaily Planet Daily reports that the prediction market platform Kalshi recorded 15.4 million visits in the United States in July, representing an approximate 1520% increase from under 1 million visits in August 2025; U.S. visits accounted for nearly 80% of its total traffic, up from 72.8% during the same period.
Kalshi's monthly notional trading volume in August was approximately $40 billion, representing a roughly 4,500% increase compared to $874 million in the same period last year. During the same period, the monthly notional trading volume of the prediction market industry rose from approximately $2 billion to $50.7 billion, with Kalshi accounting for nearly 79% of the latest total.
Sports contracts accounted for 83% of Kalshi's July trading volume. The legal status of Kalshi's sports contracts—whether they are subject to federal regulation or state gambling laws—is under dispute, and New Jersey has referred the matter to the U.S. Supreme Court.
In July, Canada had approximately 450,000 visits and the UK had approximately 296,000 visits, both significantly higher than the roughly 50,000 and 31,000 visits in August 2025. Users in both regions are currently prohibited from directly accessing or trading on Kalshi under its membership agreement. Kalshi has partnered with Canadian financial services company Wealthsimple to offer nearly 4,000 eligible contracts through a standalone app. (Cointelegraph)
