U.S. visits accounted for nearly 80% of its total traffic, up from 72.8% during the same period. Kalshi's nominal trading volume in August reached approximately $40 billion, a year-on-year increase of about 4500% compared to $874 million in the same period last year. During the same period, the monthly nominal 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 made up 83% of Kalshi's trading volume in July.

In Canada, visits in July were approximately 450,000, and in the U.K., about 296,000, both significantly higher than the approximately 50,000 and 31,000 visits in August 2025, respectively. 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 an independent application. (Cointelegraph)
