New York Targets Kalshi in Major Lawsuit, Claiming Unlawful Gambling Operations
In a significant legal move, New York has filed a lawsuit against prediction market platform Kalshi, alleging it operates as an “illegal, unlicensed gambling operation” and seeking to halt the company’s activities while demanding forfeiture of profits, potentially amounting to billions.
This lawsuit adds New York to the list of states challenging the regulation of prediction markets, which have rapidly expanded in popularity. Kalshi, along with similar platforms, maintains that they are federally regulated and thus beyond the jurisdiction of state laws.
Elisabeth Diana, speaking for the New York-based Kalshi, expressed disappointment with the state’s actions, stating, “It’s sad to see this type of political theater from the leadership in our own state. States can’t just shut down a federally licensed exchange.”
Kalshi and others like it facilitate trading on a broad array of events, from sports to political outcomes, which has prompted legal scrutiny. Governor Kathy Hochul and Attorney General Letitia James have spearheaded the lawsuit, filed in Manhattan’s state Supreme Court.
Attorney General James emphasized the lawsuit’s goal to safeguard against underage betting and mitigate gambling addiction risks, claiming that prediction markets are simply gambling platforms under a different guise. She stated, “By ignoring our laws, Kalshi is running an illegal operation and harming New Yorkers in the process.”
The legal action seeks to have Kalshi relinquish any unlawful earnings, compensate affected consumers, and face fines potentially tripling their gains. Preliminary estimates put the damages and costs at around $36 billion.
Recently, Kalshi engaged with New York officials regarding tax obligations and consumer protections, amid escalating legal tensions. New York’s legal pursuit mirrors its April actions against platforms Coinbase and Gemini over similar allegations.
State authorities argue that prediction markets qualify as gambling due to the uncertain nature of event outcomes. They also contend that Kalshi has not secured a necessary state Gaming Commission license and has avoided tax responsibilities akin to those of licensed casinos and mobile sports betting operations.
The state also cites that while Kalshi permits users aged 18 to 20, New York mandates sports betting participants be at least 21. Last October, the Gaming Commission instructed Kalshi to cease its “unlicensed mobile sports wagering platform” activities, leading Kalshi to file a federal lawsuit, which is ongoing.
Kalshi argues that their model differs from traditional gambling, functioning more like a stock market where users trade against each other, with prices determined by trading activities, from which the platform earns a fee.
The ongoing legal debate involves federal jurisdiction claims, with prediction markets asserting that the U.S. Commodity Futures Trading Commission (CFTC) exclusively oversees their transactions. In a February statement, a CFTC official declared the agency’s intent to challenge state efforts that could undermine its authority.
Despite federal oversight claims, states maintain that the bulk of prediction market business involves sports betting, which falls under state regulatory power, distinct from commodities and futures trading.
In a related development, a federal judge recently paused Minnesota’s impending ban on prediction markets, marking a temporary setback for state regulatory efforts. Earlier, Arizona faced a similar judicial intervention against its enforcement actions.
The legal landscape continues to evolve with numerous lawsuits, as states attempt to leverage their gambling laws against Kalshi, Polymarket, and other operators. In April, the federal government contested regulatory attempts by Connecticut, Arizona, and Illinois.
