Prediction Market Kalshi Processes $40 Billion in World Cup Trades Amid State Tax Disputes

During the 2026 FIFA World Cup, the prediction market platform Kalshi recorded an estimated $40 billion in event contract trades, despite this unprecedented trading volume, Kalshi maintains that it operates as a federally regulated financial exchange rather than a traditional sportsbook. Consequently, the company asserts it is exempt from state-level sports betting taxes. This classification has initiated a complex jurisdictional dispute between federal commodities regulators and state gaming commissions, drawing intense scrutiny from the established gambling industry.

Unlike conventional sportsbooks, which are licensed on a state-by-state basis and subject to specific gaming taxes, Kalshi functions under the oversight of the Commodity Futures Trading Commission (CFTC). The platform allows users to trade financial derivatives based on the outcomes of real-world events. Because Kalshi categorizes its offerings as event contracts rather than sports bets, it avoids state tax rates that can reach as high as 51 percent in jurisdictions like New York. This regulatory asymmetry has allowed prediction markets to capture a significant share of consumer demand during the World Cup, introducing millions of users to event-contract trading.

The rapid expansion of prediction markets has prompted legal action and legislative responses from multiple states seeking to protect their tax bases and enforce local gambling laws. The American Gaming Association (AGA) estimates that the proliferation of platforms like Kalshi has displaced more than $1 billion in annual state sports betting tax revenue. Bill Miller of the AGA recently addressed the financial impact, stating that the “evasion of state and tribal laws” has cost communities substantial revenue, adding that “this siphoning will intensify as ‘prediction markets’ continue refusing to comply with state and tribal law.” Furthermore, state officials have initiated lawsuits to halt unlicensed operations. Following the initiation of legal proceedings in Kentucky, Attorney General Russell Coleman stated, “Kalshi and Polymarket are operating illegal sportsbooks in Kentucky and breaking our laws.”

In response to state-level pushback, Kalshi maintains that its operations are fully compliant with federal commodities laws and that state gaming regulators lack jurisdiction over CFTC-approved financial products. While states like New York pursue billions in damages based on retroactive applications of sports betting taxes, others are exploring new legislative frameworks to adapt to the market. For example, North Carolina recently drafted budget provisions to impose a specialized 6 percent tax rate on prediction market operators, acknowledging their distinct operational model while still capturing state revenue.
