Kalshi US traffic surges as legal scrutiny intensifies

Kalshi’s US audience has expanded at a remarkable pace over the past year, even as the prediction market operator faces deeper legal and regulatory challenges. The company’s growth has been concentrated in the United States, where most of its traffic now originates. That combination has put Kalshi at the center of a broader fight over how event contracts should be classified and supervised.

Traffic growth and market reach

Kalshi drew 15.4 million visits from the US in July, compared with just under 1 million in August 2025, according to Similarweb estimates reviewed by Cointelegraph. That works out to an increase of more than 1,500% in less than a year. US traffic represented nearly four-fifths of all visits in July, up from about 73% a year earlier, suggesting the platform’s reach has widened while remaining strongly tied to its home market.

The traffic surge points to stronger public interest in prediction markets, but it also highlights how quickly Kalshi has scaled its US-facing business. The company’s growth in visits has been matched by a faster rise in trading activity, indicating that the platform is not just attracting more attention but also more active participation. That matters for a business model built on event contracts, where user engagement is closely linked to volume.

Legal pressure on sports contracts

The same expansion has drawn sharper scrutiny from regulators and courts over Kalshi’s sports-related offerings. The core dispute is whether those contracts should be treated as products under federal oversight or as forms of gambling governed by state law. New Jersey has escalated that conflict by bringing the matter before the US Supreme Court.

That legal uncertainty is significant because the answer could determine where Kalshi is allowed to operate and how its products are supervised. If courts side with state gambling regulators, the company could face tighter restrictions in some markets. If federal oversight prevails, prediction markets may gain more room to expand, though the rules would still depend on the outcome of ongoing proceedings.

The dispute has implications beyond Kalshi itself because it touches a fast-growing segment of financial and wagering-like products. Prediction markets have become more visible as users look for ways to trade on real-world outcomes, from politics to sports. Kalshi’s recent traffic figures show that demand is rising, but the company’s legal path remains unsettled while the courts weigh where these contracts belong.
