New York sues Kalshi over alleged illegal gambling operation; seeks to treat prediction market like sportsbook for tax purposes

New York state has filed a lawsuit against Kalshi, alleging the prediction market operator is running an illegal gambling operation without a state license. Attorney General Letitia James claims this could lead to significant tax implications, as Kalshi's operations may be classified as gambling under state law.

New York state has initiated legal action against Kalshi, a prominent prediction market provider, claiming it operates an illegal gambling operation. The lawsuit, filed by Attorney General Letitia James, alleges that Kalshi has failed to obtain a necessary state gambling license and is evading taxes required of licensed gambling entities.1245

James stated, “New York’s gambling laws protect children from underage betting and help combat gambling addiction. No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple.” The lawsuit seeks to enjoin Kalshi’s operations, impose fines, and require the forfeiture of profits.3

Kalshi, which is regulated by the CFTC, currently pays corporate income tax at a rate of 7.25%, significantly lower than the gambling tax rate of 51% that sportsbooks like FanDuel face on their net gaming revenue. If Kalshi is classified as a gambling provider, it could face a steep tax increase, impacting its profitability.78

The lawsuit also raises concerns about underage access, as Kalshi allegedly allows users aged 18 to 20 to participate, while New York law mandates a minimum age of 21 for mobile sports betting. Kalshi's spokesperson criticized the lawsuit as political theater, asserting that it could drive users to unregulated offshore markets.

This legal battle reflects broader tensions between state and federal regulations, as Kalshi and similar platforms argue they should be governed exclusively by federal law. The outcome could set a precedent for how prediction markets are treated under U.S. law.

Key Insight
“The lawsuit seeks forfeiture of profits, restitution, and fines three times Kalshi's profits, and alleges 18-to-20-year-olds can bet despite New York's 21+ age limit. The CFTC warns one state could 'bring entire federally regulated markets to the brink of destruction.'”
