What Happened
In March 2024, Kalshi, a federally regulated prediction market, registered an estimated $2 billion in handle-equivalent volume, according to figures from Eilers & Krejcik Gaming shared via Casino.org. This positions Kalshi as the fourth-largest operator by handle-per-adult in the US betting sector, overtaking major industry incumbents such as BetMGM and Caesars in total monthly volume.
While Kalshi is not licensed in the traditional sports betting framework and instead operates under Commodity Futures Trading Commission (CFTC) oversight, its player liquidity and market activity now statistically rival those of top national sportsbooks. The company has maintained that, despite the similarity in product format, it is part of the financial services sector, differentiating itself from state-licensed betting operators.
Why It Matters
Kalshi’s ascension into the top echelon of US wagering operators signals a profound shift at the intersection of gambling, financial services, and regulatory frameworks. For the first time in the post-PASPA era, a federally regulated prediction market has exceeded the scale of some of the most prominent sports betting brands in the country, at least in terms of raw betting volume per adult.
$2 billion March handle-equivalent — Kalshi's monthly volume now positions it ahead of established operators like BetMGM and Caesars and puts it near the top of the US betting landscape.
This development is significant for several reasons. First, it demonstrates the consumer appetite for prediction markets with structures distinct from traditional sportsbooks. Kalshi enables traders to take positions on a wide array of real-world outcomes (such as economic indicators, political events, and, in certain cases, sports-adjacent questions), blending speculative financial activity with the engagement factors of gambling.
Second, Kalshi’s status as a CFTC-regulated entity challenges existing state-level regulatory paradigms. Whereas traditional online sportsbooks must navigate a patchwork of state licensure, taxation, and responsible gambling obligations, Kalshi operates under federal oversight, leveraging this regulatory vector to scale rapidly across state lines.
Lastly, Kalshi’s market scale is forcing a re-examination of what constitutes “betting” versus “trading” in the US context. As these boundaries blur, there are implications for tax policy, player protection, and the competitive landscape for both incumbent sportsbooks and financial exchanges.
Industry Context
Kalshi's rise comes amid growing interest in prediction markets as vehicles for both speculation and hedging, particularly within the context of regulatory arbitrage. Legal US online sportsbooks, regulated primarily on a state-by-state basis since the repeal of PASPA in 2018, have faced significant barriers to multi-state expansion, marketing, and product innovation. In contrast, Kalshi, much like the earlier CFTC-regulated platform PredictIt, has been able to serve users more broadly as an “event contracts” exchange under national law.
Observers note that handle volume, while a useful metric, is not directly comparable between sportsbooks and financial prediction markets due to differences in product structure, margin, and customer intent. However, the magnitude of Kalshi’s figures underscore an increasing preference among certain user segments for prediction-based products over conventional sports bets.
Kalshi itself has faced regulatory scrutiny regarding the types of events it is permitted to list—political contracts, in particular, have attracted both investor and regulator attention. Nevertheless, the $2 billion figure from March demonstrates that even with product limitations, a federally regulated prediction exchange can compete on scale with traditional gambling enterprises.
What Happens Next
The rapid growth of Kalshi is likely to prompt renewed interest from both regulators and operators regarding the appropriate classification and oversight of prediction markets in the US. Key questions include whether other financial exchanges will follow Kalshi’s lead, whether state regulators will seek greater jurisdictional input, and how consumer protection standards will evolve at the intersection of gambling and trading.
The debate around the regulatory perimeter for products like Kalshi is increasingly relevant as innovation continues to blur category lines. Market participants and policymakers alike are watching closely as the implications for tax collection, player care, and competitive dynamics become clearer.
