New York has opened a major legal challenge against prediction market operator Kalshi, accusing the company of running unlawful gambling in the state and seeking sweeping financial and operational remedies. State officials want the court to stop Kalshi from offering the relevant contracts in New York, return money to users where appropriate, and impose penalties that court filings say could reach at least $36 billion after a full accounting.
State alleges unlicensed gambling
According to the complaint, Kalshi offers markets that let users wager on outcomes tied to sports, culture and elections without holding a license from the New York State Gaming Commission. The lawsuit argues that these event contracts fall within New York’s legal definition of gambling, despite being presented as prediction markets.
The state says the platform exposed New York residents to personal and financial harm and alleges that some users may have included people below the state’s legal gambling age of 21. New York also claims Kalshi avoided tax obligations tied to activity the state considers gambling.
Injunction request and damages claim
Alongside the lawsuit, New York is asking for a temporary restraining order aimed at halting Kalshi’s relevant event contracts in the state while the case proceeds. The attorney general is also seeking broader relief, including restitution for users, disgorgement of proceeds, and civil penalties.
Court papers described in the report indicate the state wants penalties of up to three times Kalshi’s gains, plus $100,000 for each offering at issue. The filings further state that compensatory damages could amount to at least $36 billion, though that figure remains subject to a full accounting.
Officials frame case as consumer protection
Governor Kathy Hochul said New York’s gambling laws are intended to protect consumers, reduce problematic gambling, support public services and ensure operators follow the same standards. Attorney General Letitia James said platforms such as Kalshi are gambling businesses regardless of how they are branded.
The case therefore goes beyond a licensing dispute and centers on how New York classifies prediction-market contracts when they are made available to residents of the state. If the court accepts the state’s view, Kalshi could face both a block on operating there and a very large financial judgment.
Kalshi’s place in the market
The dispute lands at a notable moment for the company. The Block described Kalshi as the largest prediction market platform by trading volume, with significant activity in June. That scale helps explain why the New York action is being watched closely: the outcome could affect not only Kalshi’s business in the state but also the broader debate over whether event-based trading markets should be treated as regulated financial products or as gambling under state law.
The report also noted that the Commodity Futures Trading Commission had previously sought a temporary restraining order in enforcement matters involving Kalshi and other platforms. New York’s lawsuit adds a separate state-level challenge, combining claims over licensing, consumer protection, tax obligations and the legal status of the contracts themselves.
