Prediction market operator Kalshi is facing mounting legal pressure across the United States, with disputes in Nevada and California highlighting the growing conflict between state gambling regulators and federally regulated event-trading platforms.
The company, which allows users to trade contracts tied to the outcomes of sports, political, economic and entertainment events, has become the focal point of a broader debate over whether prediction markets should be treated as financial products or gambling activities.
In Nevada, regulators have taken some of the most aggressive action against Kalshi. The state’s gaming authorities argue that the platform is effectively offering sports betting without obtaining the licenses required under Nevada law. Earlier this year, a Nevada court granted a temporary restraining order preventing Kalshi from operating certain prediction market products in the state, marking one of the most significant legal setbacks the company has faced. The dispute has continued through multiple court proceedings, with regulators seeking to maintain restrictions on Kalshi’s activities.
Nevada officials contend that Kalshi’s sports-related contracts amount to wagering and should therefore fall under state gaming oversight. Kalshi, however, maintains that its products are federally regulated derivatives overseen by the Commodity Futures Trading Commission (CFTC), arguing that federal law pre-empts state enforcement efforts.
Meanwhile, California has emerged as another key battleground. Tribal gaming groups have challenged Kalshi’s operations, claiming that the company’s offerings infringe on protections granted to tribal gaming under federal law. However, a federal court in California previously declined to block Kalshi’s activities, finding that the plaintiffs had not demonstrated a sufficient likelihood of success under the Indian Gaming Regulatory Act. The ruling was viewed as an important victory for the prediction market operator.
Despite that outcome, California regulators continue to monitor developments closely. State officials have indicated they remain unconvinced that federal oversight automatically prevents states from enforcing their own gambling laws, leaving open the possibility of future legal action.
The disputes in Nevada and California form part of a wider national struggle over prediction markets. Kalshi has faced lawsuits, injunction requests, cease-and-desist orders and regulatory scrutiny in multiple jurisdictions, while state authorities argue that the rapid expansion of event-trading platforms risks bypassing established gambling regulations, licensing systems and consumer protections.
At the center of the debate is a fundamental legal question: whether prediction market contracts are financial instruments regulated exclusively by the CFTC or a form of gambling that remains subject to state control. Conflicting court decisions across the country suggest the issue is far from settled, and industry observers increasingly believe the matter could eventually be decided by higher federal courts.
