Kalshi emerged as a dominant platform for World Cup wagering, yet the company maintains it is not a sports betting operator. The platform positions itself as a federally regulated financial product where bettors wager against each other rather than against a house. This distinction sits at the center of ongoing debates about taxation and regulation in the growing prediction market sector.
Since the soccer tournament began, Kalshi has reported record activity, saying it has taken in more than $25 billion in sports wagers on its platform. Analysts, however, project that online sportsbooks such as DraftKings and FanDuel will log about $4 billion in bets across all 104 World Cup matches. The gap underscores a policy and regulatory battle over how Kalshi and similar prediction markets fit into the broader gambling landscape and tax regime.
Kalshi argues that its model functions without a traditional house, with users betting against each other and Kalshi earning fees on transactions rather than taking on risk of losses. The app also enables bets on a range of non-sports outcomes, including elections, the president’s word choices, or entertainment milestones, illustrating the breadth of its market offerings. Kalshi spokeswoman Elisabeth Diana emphasizes that, unlike sportsbooks, Kalshi does not restrict bets or ban frequent big winners. “Just like the stock market, you can exit your position at any time. It’s a fairer, less predatory platform,” Diana said.
Whether Kalshi is an unlicensed sportsbook or a new kind of finance app is a disputed question that sits at the heart of more than 20 pending federal lawsuits, potentially affecting billions of dollars in tax revenue and the future of the prediction market industry. Kalshi notes that sports are the most popular wagering category on its platform, typically accounting for about 80% to 90% of all bets placed.
In the midst of the World Cup betting surge, Kalshi and other prediction market operators have been touted as a legal backdoor to expand sports betting without paying state gaming taxes. The platform’s expansion into states where traditional sports betting is restricted—for example, California and Texas—has been aided by its argument that it is regulated as a financial product rather than a gambling site. The Trump administration’s stance has supported Kalshi’s position that it is not gambling, a stance that continues to provoke legal scrutiny as regulatory debates unfold.
From a bettor’s point of view, Kalshi and sportsbooks are described by some analysts as essentially similar in function. Victor Matheson, an economics professor at the College of the Holy Cross who specializes in sports gambling, said, “From a bettor’s standpoint, Kalshi and sportsbooks are basically identical.” Kalshi’s effort to distance itself from traditional sports betting is reinforced by advertising campaigns that positioned Kalshi as an alternative to “predatory” sportsbooks, though NPR noted some of these ads were later removed from the library.
Kalshi has also faced questions about its regulatory status in the broader policy debate surrounding tax treatment and enforcement. The company notes that prediction markets can sit outside conventional gambling tax structures, which has drawn opposition from some state lawmakers and gaming advocates. Tax issues remain a focal point as states consider how prediction markets should be taxed and regulated.
While Kalshi claims to comply with all applicable laws and to view taxation as a shared responsibility, the broader policy environment remains contested. The debate encompasses questions about how prediction markets should be taxed relative to traditional gambling operations, and whether these platforms should be treated as financial exchanges or as sportsbooks under state and federal law.
On the other side of the industry, sportsbook operators have argued that prediction markets may erode tax bases while offering a similar customer experience. DraftKings and FanDuel have reported upticks in quarterly profits in recent months, reflecting a shift toward smaller bets and a reduction in cash bonuses, according to Brad Allen, a gambling industry analyst at Eilers & Krejcik Gaming. The sector’s tax burden remains a political issue, with operators paying state taxes and licensing fees in myriad jurisdictions. NPR’s analysis indicates that total taxes paid by sports gambling operators amount to about $4 billion annually across more than 30 states where mobile betting is legal, though tax rates vary widely by state.
Industry observers note that the growth of Kalshi and other prediction markets has not yet meaningfully dented sportsbook profits, a gap stemming in part from a decline in the average size of bets or “handle” across the sector. Kalshi’s platform has, however, expanded access by lowering age requirements in some contexts and by enabling bets in states where conventional sports betting is restricted, a move some observers view as strategically expanding the market.
As the regulatory and tax framework for Kalshi and its peers continues to evolve, the company’s leadership and investors monitor policy developments that could reshape the trajectory of prediction markets. Kalshi asserts it remains committed to lawful operations and to engaging with regulators as it defends its designation as a financial exchange rather than a sportsbook.
The World Cup betting surge thus sits at the intersection of a legal debate over how to classify and tax prediction markets, the economics of a rapidly expanding form of wagering, and the political dynamics surrounding gaming policy in the United States.
