Kalshi is taking Illinois to court. The prediction market platform sued Attorney General Kwame Raoul and Governor J.B. Pritzker last Tuesday after the state classified prediction markets as unlicensed sports wagering operators and slapped new taxes on them.
The stakes are high. If the law stands, Kalshi would owe taxes no other state is charging and could face felony charges. Starting July 1, Illinois planned to impose a 1.75% tax on the first 5 million sports wagers per fiscal year, then 3.5% on everything after. The state license would cost $15 million for the first four years, then $1 million annually. Kalshi, valued at $22 billion, called the license too costly and burdensome.
The core legal question: who regulates prediction markets? Kalshi argues the CFTC has exclusive authority. States like Illinois say these are sports bets dressed up as event contracts, and they want a cut. The CFTC itself sued Illinois in April, claiming the state was interfering with federally sanctioned swap contracts.
Kalshi draws a sharp distinction. In a prediction market, traders do not bet against the house. Every yes position has an equal no position. The platform frames event contracts as financial hedging tools, not gambling. Media companies hedge viewership risk. Advertisers weigh sponsorship value. Insurance companies manage ticket revenue exposure.
States are not buying it. Illinois logged its most devastating year of legal sports betting losses on record in 2025, with residents losing close to $1.5 billion. The urgency is real, especially with Meta reportedly exploring its own sport-wagering platform.
Prediction markets just had their biggest week ever, driven by the NBA Finals, World Cup, and Stanley Cup. The regulatory patchwork is expanding fast. Kalshi needs clarity before more states pile on.
