Kalshi, a prediction market platform, has generated approximately $40 billion in sports-related trading activity during the World Cup tournament, according to analytics firm Ticker Tracker. This figure substantially exceeds projections for traditional sportsbooks like DraftKings and FanDuel, which analysts expect to process around $4 billion across all 104 matches of the tournament.
The company maintains that it operates as a federally regulated financial product rather than a sports gambling application. Kalshi positions itself differently from traditional sportsbooks by allowing users to trade against each other rather than against the house, charging transaction fees instead of profiting from losing bets, and offering wagering on diverse topics including elections and entertainment. However, sports betting accounts for approximately 80 to 90 percent of all activity on the platform, encompassing bets on match outcomes, player performance, and other sports-specific outcomes.
The distinction between prediction markets and sportsbooks has become a contentious legal and regulatory matter, with over 20 federal lawsuits pending. Industry observers argue the platforms function identically to sportsbooks from a user perspective, while Kalshi contends its regulatory framework differs fundamentally. The disagreement carries significant implications for tax revenue, as prediction markets currently operate in states where sports betting is prohibited and accept bets from 18-year-olds in jurisdictions where the legal age for sportsbooks is 21.
Sportsbook operators highlight that licensed betting sites pay substantial taxes ranging from 6.7 percent in Nevada to 51 percent in New York, with the industry collectively paying approximately $4 billion annually in state taxes. These revenues fund various public programs including education and infrastructure. Some states have responded by attempting to regulate prediction markets, with North Carolina implementing a 6 percent tax, while others including Minnesota and Michigan have enacted restrictions or bans.
The federal Commodity Futures Trading Commission, which oversees prediction markets, has filed lawsuits against multiple states attempting to regulate the sector. Legal experts anticipate the matter may eventually reach the U.S. Supreme Court to determine the appropriate regulatory classification and tax treatment of prediction market platforms.
