Nevada Regulators Sue to Shut Down Polymarket’s Over Unlicensed Wagering in Landmark US Case
Regulator seeks court order to halt alleged unlicensed wagering activity in Nevada.
Nevada Gaming Control Board has filed a civil enforcement action against Polymarket and related entities, escalating regulatory pressure on prediction market platforms operating without state gaming licences.
In a filing submitted to the District Court for Carson City on 16 January 2026, the Board named BLOCKRATIZE, INC., QCX LLC, and ADVENTURE ONE QSS, INC., all operating under the Polymarket brand, as defendants. The action seeks a judicial declaration and permanent injunction that would prevent Polymarket from continuing to offer what the regulator classifies as unlicensed wagering activity in Nevada.
According to the complaint, Polymarket operates a derivatives exchange and prediction market that offers event-based contracts to users through its mobile application. These contracts are made accessible to individuals located in Nevada, a factor the Board says places the activity squarely within the scope of state gaming law.
The Nevada Gaming Control Board argues that sports-related event contracts, and certain other outcome-based contracts, meet the statutory definition of wagering under Nevada Revised Statutes (NRS) 463.0193 and 463.01962. Under this interpretation, any entity offering such products to Nevada residents must hold a valid gaming licence issued by the state.
In its filing, the Board alleges that Polymarket’s operations violate multiple provisions of Nevada law, including NRS 463.160, NRS 463.350, NRS 465.086, and NRS 465.092. These statutes govern the licensing, regulation, and enforcement of gaming activity, as well as prohibitions against unlawful gambling operations.
The enforcement action reflects Nevada’s long-standing public policy approach to gaming oversight. State law emphasises that the gaming industry plays a critical role in Nevada’s economy and public welfare, and therefore must be strictly licensed, controlled, and regulated to protect public health, safety, and integrity.
This case adds to a growing list of regulatory challenges facing prediction market platforms in the United States. As regulators continue to assess whether event-based contracts resemble financial instruments or gambling products, enforcement actions such as Nevada’s highlight the legal uncertainty surrounding these hybrid models.
The outcome of the case could have broader implications for how prediction markets operate in US jurisdictions with established gaming frameworks, particularly those that maintain strict licensing and enforcement standards.
