Kalshi, a prediction markets platform, has crossed a major threshold, recording over $100 billion in lifetime trading volume as of Friday. The momentum didn’t stop there — the platform also achieved a daily trading volume exceeding $1 billion on both Saturday and Sunday for the first time. The Event Horizon newsletter by Dustin Gouker was quick to spotlight these milestones, underscoring the rapid growth of prediction markets in the United States. It’s important to note, however, that trading volume is distinct from sports betting handle.

Milestones Reflect Rapid Expansion
Kalshi’s recent milestones are fueled by the increasing sports-related activities on the platform, with football and the World Cup driving much of the action. Over just four days of the tournament, traders funneled $750 million into the markets. Another major contributor to Saturday’s volume was the NBA Finals final game, which accounted for over $200 million. But this growing engagement is pushing prediction markets into mainstream sports betting discussions.
Volume Isn’t Handle
A critical distinction between prediction markets and traditional sportsbooks is the concept of trading volume versus handle. While trading volume includes both opened and closed trades, handle specifically measures the amount wagered on a sporting event. This differentiation is important because high trading volumes can give the impression of greater economic activity than what’s genuinely comparable to traditional sportsbook wagering.
Kalshi’s Growth vs. Sportsbooks
Even as Kalshi continues to grow, its sports business doesn’t yet rival the economic impact of traditional sportsbooks. In March, for instance, parlay trades surged, constituting over 20% of Kalshi’s weekly sports trading volume, a remarkable increase from less than 1% at launch. Yet, the prediction markets still fall short on pricing, hold, and product depth compared to conventional sportsbooks.
Implications for the Gambling Ecosystem
Kalshi’s rise is drawing attention from sports betting operators, regulators, and legislators. As the platform’s volume climbs, it challenges the perception of prediction markets as a niche endeavor. This growth places additional pressure on the Commodity Futures Trading Commission and other regulators to clearly delineate between event contracts and gambling-style products. The increasing role of sports trading in Kalshi’s business model only amplifies this issue. What’s next? With Kalshi’s growing footprint, regulators will likely be pushed to address these distinctions more clearly, possibly as soon as the upcoming regulatory review sessions.
