A Nevada district court judge has issued a temporary restraining order against prediction market company Kalshi, effectively halting its operations in the state. The order, granted Friday by the First Judicial District Court in Carson City, represents a significant escalation in the state's campaign to regulate what it views as unlicensed sports wagering disguised as financial contracts.
The Nevada Gaming Control Board (NGCB), which sought the injunction, argues that Kalshi's event contracts—which allow users to speculate on outcomes like election results or sports games—are functionally identical to sports bets. State law requires such operations to be licensed and subject to rigorous oversight of executives and business practices. "Prediction markets, to the extent they facilitate unlicensed gambling, are illegal in Nevada," said NGCB Chairman Mike Dreitzer in a statement. "We have a statutory duty to protect the public. We want people in the state to wager safely at a licensed book."
Dreitzer directly challenged Kalshi's public claims of operating legally nationwide. "Kalshi has repeatedly stated that its operations are legal in 50 states, which is clearly not true," he stated. Regulators contend the company's model, which lacks the federal oversight applied to licensed Nevada sportsbooks, creates vulnerabilities that could undermine the integrity of the state's tightly controlled gaming industry.
The legal action follows similar moves by other states. Earlier this week, Arizona became the first state to file criminal charges against Kalshi. Nevada itself had been in discussions with the company but opted to pursue court intervention after those talks failed to resolve the dispute. This follows the state's February filing for an injunction against Coinbase to prevent it from offering similar event contracts.
The NGCB's news release emphasized the foundational policy behind Nevada's aggressive stance: "Nevada's public policy, as expressed by the Legislature, is that the gaming industry is vitally important to the economy of the state and the general welfare of the inhabitants and therefore must be licensed, controlled, and assisted to protect the public health, safety, morals, good order, and general welfare of the inhabitants of the state."
The American Gaming Association (AGA) immediately endorsed Nevada's enforcement action. "Nevada and the Nevada Gaming Control Board's successful effort to secure a Temporary Restraining Order against Kalshi is a critical step in addressing sports event contracts offered by prediction markets," said AGA President and CEO Bill Miller. He praised the state's "decisive enforcement to uphold its laws, protect its consumers and defend the integrity of its regulated market."
The controversy around prediction markets has also reached Congress. In February, after reports that Kalshi had facilitated $871 million in contracts related to the Super Bowl, Representative Dina Titus (D-Nev.) introduced federal legislation aimed at closing what she sees as a regulatory loophole. "Prediction markets should not be able to circumvent state gaming laws," Titus argued. "Consumers deserve transparency, accountability, and protection against such predatory practices." Her effort is part of a broader, bipartisan push in Congress to ban sports-related contracts on these platforms.
This legal and regulatory clash occurs against a backdrop of heightened scrutiny over jurisdictional authority and consumer protection in emerging digital markets. The outcome in Nevada could set a precedent for other states grappling with how to classify and regulate prediction markets. The case also highlights the ongoing tension between innovative financial technologies and established regulatory frameworks designed for traditional industries.
