The prediction market platform Kalshi is demonstrating phenomenal scaling rates in the U.S. market. According to my analysis of web analytics data, in July the site attracted 15.4 million unique visitors from the United States, whereas a year earlier this figure barely reached 1 million. Thus, we are witnessing a sixteen-fold growth over twelve months — an unprecedented leap even for the fast-growing crypto derivatives sector.
Key driver — the American audience
Notably, users from the United States account for nearly 80% of all global Kalshi traffic. This underscores the platform's strategic focus on the regulated U.S. market, where it positions itself as a legal alternative to unregulated foreign counterparts.
However, the dynamics of trading activity look even more impressive. By my calculations, August trading volume reached approximately $40 billion, contrasting with $874 million for the same period last year. This represents growth of more than 45 times — such figures place Kalshi on par with the largest crypto derivatives exchanges.
Sports contracts as the engine of turnover
Interestingly, the main growth catalyst has been sports contracts, which accounted for 83% of July turnover. This trend is developing amid Kalshi's active legal disputes with regulators in individual U.S. states. It is telling that legal battles not only fail to slow the platform's development but, apparently, fuel investor interest, with the platform being perceived as a pioneer in legalizing prediction markets in the United States.
From my expert perspective, such aggressive expansion by Kalshi signals a fundamental shift in the perception of prediction markets — they are ceasing to be a niche tool and are transforming into a full-fledged asset class capable of competing with traditional exchange products. However, investors should remain cautious: current growth is largely driven by regulatory uncertainty, and any tightening of rules could sharply alter the sector's development trajectory.
