Kalshi U.S. visitors surge more than 1,500 percent as sports betting drives growth

U.S. prediction market platform Kalshi’s U.S. website visitors jumped more than 1,500 percent in less than a year, driven by a surge in sports prediction contracts and a sharp rise in trading. Similarweb estimates showed 15.4 million U.S. visits in July, up from under 1 million in August 2025. Dune Analytics data put August notional volume at about $40 billion, while legal disputes grow over whether the products are financial instruments or sports gambling.
