Nevada Scores Preliminary Injunction Against Polymarket in Ongoing Prediction Market Battle
Nevada has secured another legal victory in its push to regulate prediction markets as a form of wagering. First Judicial District Court Judge Jason Woodbury granted a preliminary injunction to the Nevada Gaming Control Board against Polymarket. The move forces the operator to temporarily cease business in the state for the duration of the lawsuit if upheld.
The Nevada Gaming Control Board reported a written order from the court is forthcoming. This latest ruling underscores the state’s aggressive stance against unlicensed prediction market activity. For gaming executives and operators, it signals continued regulatory friction as the lines between event contracts and traditional sports betting remain contested.
Judge Jason Woodbury’s Ruling and Immediate Impact
Judge Jason Woodbury ruled in favor of the Nevada Gaming Control Board’s motion for a preliminary injunction. Polymarket will be ordered to halt operations in Nevada until the lawsuit concludes. The board has taken decisive action in recent months to halt the operations of other prediction markets in the state.
Because of previously entered preliminary injunction orders, Kalshi and Coinbase are prohibited from offering or facilitating sports-, election-, and entertainment related event contracts in the state of Nevada. This builds on a legal battle that began in January when the board filed a civil enforcement action against Polymarket in the District Court for Carson.
In its complaint, the board sought a declaration and injunction to stop Polymarket from offering unlicensed sports betting. The board considers offering sports event contracts, or certain other events contracts, to constitute wagering activity under NRS 463.0193 and 463.01962. Entities offering such contracts must therefore be licensed.
Mike Dreitzer, Nevada Gaming Control Board Chairman, said in a released statement: “We are very pleased with Judge Woodbury’s ruling and will continue to vigorously enforce Nevada law to safeguard gaming in our state.”
From my perspective after decades observing the evolution of gaming regulation, these injunctions highlight how states are treating prediction markets as an extension of sports betting rather than a separate derivatives category.
Broader Pattern of Enforcement Against Prediction Markets
The Nevada Gaming Control Board has lodged several victories against prediction market operators since beginning its legal fight last year. On Friday, March 20, the First Judicial District Court granted the board’s request for a temporary restraining order against Kalshi. That cessation has since been extended, and Kalshi remains unavailable in the state.
The same court granted a preliminary injunction motion on March 26 regarding Coinbase. This forced the operator to cease offering its sports event and entertainment contracts in Nevada.
These actions reflect a pattern. State gaming regulators maintain that the markets need to be beholden to regulations, taxes, and license fees that sports betting and gaming operators are required to follow. The central question in these court battles is who holds authority over sports event contracts and prediction markets in general.
Risks, Counterarguments, and the CFTC Debate
Prediction market operators including Robinhood, Kalshi, Coinbase, and Crypto.com argue that state regulatory bodies do not have the right to intrude on the federal government’s exclusive authority. They have filed lawsuits in several states asserting that only the CFTC can legally block contracts from being offered to customers.
This position carries real risk for operators. A prolonged shutdown in a key jurisdiction like Nevada disrupts user access, revenue streams, and market momentum. It also creates uncertainty for client-partners evaluating nationwide rollout strategies.
Yet the counterargument from states is equally pointed. Without licensing and oversight, these platforms could bypass consumer protections, taxation, and responsible gaming standards embedded in sports betting frameworks. The tension represents a structural shift in how event-based wagering is classified.
One limitation in the current landscape is the lack of clear federal guidance to resolve these overlapping claims. Until that arrives, operators face a patchwork of state-level injunctions that can halt operations abruptly.
Operational and Strategic Implications for Industry Executives
For gaming operators and executives, this ruling is more than a single-state enforcement action. It reinforces the need to model regulatory risk into expansion plans, especially in jurisdictions with established gaming control boards. Prediction markets sit at the convergence of derivatives, sports betting, and emerging verticals, but that positioning invites scrutiny.
Companies must weigh the speed of innovation against the cost of litigation and potential injunctions. Those already licensed for sports betting may hold an advantage in navigating these disputes. Others operating in gray areas could face similar preliminary injunctions.
The Bottom Line is that Nevada’s success in securing injunctions against Polymarket, Kalshi, and Coinbase signals a continued state-level push to assert authority over prediction markets. While operators maintain the CFTC should hold exclusive sway, the practical reality is ongoing legal battles that disrupt service and demand strategic adaptation. Industry executives should monitor how these cases influence broader regulatory clarity, as the resolution will shape access, compliance costs, and competitive positioning for years ahead.
