In a significant legal confrontation, Kalshi, a federally regulated derivatives exchange, has initiated a lawsuit against New York in a bid to protect its sports prediction markets from state shutdown. The case, filed in the Southern District of New York, pushes back against the state’s attempts to regulate Kalshi’s offerings, asserting that federal jurisdiction, granted by the Commodity Futures Trading Commission (CFTC), supersedes state authority.
Kalshi’s Legal Battle Over New York’s Sports Prediction Ban
The complaint—KalshiEX LLC v. Robert Williams—seeks to thwart penalties imposed by the New York State Gaming Commission, which claims that Kalshi’s trading products breach local gambling laws. The lawsuit aims to secure Kalshi’s right to operate without fear of civil repercussions from state regulators.
On October 24, 2025, Kalshi received a cease-and-desist notice mandating the halt of sports-related event contracts within New York. However, Kalshi counters that the enforcement lack legitimacy since such contracts fall under federal oversight.
Regulated as a designated contract market by the CFTC, a title Kalshi achieved following an extensive review in 2020, the exchange firmly believes that it alone holds jurisdiction over its products. The CFTC’s oversight is rooted in the Commodity Exchange Act, which is designed to prevent conflicts between state and federal laws.
Kalshi facilitates event contracts on various sports outcomes, including the NCAA tournament and the U.S. Open Golf Championship. The underlying regulatory framework emphasizes that federal regulations prevail over state laws, a principle Kalshi invokes in its defense against New York’s allegations.
New York Threatens Kalshi Over Sports Contracts
New York regulators assert that these contracts fall under the umbrella of illegal sports wagering as defined by the state’s Penal Law and Racing Law, threatening both civil and criminal penalties unless Kalshi ceases its operations within New York.
In response, Kalshi stands firm in its belief that its contracts are compliant with federal law, positioning the Commodity Exchange Act as the foundation that nullifies state claims to jurisdiction. The firm points out that New York’s interference is a direct violation of the U.S. Constitution’s Supremacy Clause.
Kalshi cautions that being required to restrict access in New York would severely impact its business operations. The CFTC mandates that Kalshi functions as a national exchange, so any state-level barriers could lead to insurmountable challenges for the platform to navigate.
This unfolding legal dispute underscores the increasingly complex regulatory landscape faced by platforms such as Kalshi. It reflects a broader trend of states attempting to exert control over new financial technologies, paralleling past efforts targeting the burgeoning cryptocurrency sector.
Kalshi’s argument posits that its federally sanctioned event contracts should be openly available to participants nationwide. The exchange contends that limiting access to users in New York could jeopardize its regulatory credibility and prompt reputational implications for both consumers and business allies.
This confrontation with New York regulators epitomizes the tense dialogue surrounding financial innovation, as the state has been known to adopt a stringent posture towards other emergent markets, further complicating the path for firms operating at the intersection of innovation and regulation.
The ongoing situation not only raises critical questions about the future of prediction markets but also highlights the urgent need for clear regulatory frameworks that can accommodate these novel technologies while safeguarding consumer interests.
