Polymarket Sued By Nevada Gaming Regulator Over Sports Predictions
Summary
The Nevada Gaming Control Board (NGCB) has filed a civil enforcement action in Nevada state court against Polymarket, seeking a declaration and injunction to stop the prediction market from offering what the Board calls unlicensed wagering in violation of Nevada law. This is the first U.S. lawsuit against Polymarket.
The complaint alleges that Polymarket’s event contracts constitute wagering and cites multiple Nevada Revised Statutes the Board says were violated, including statutes that bar unlicensed gaming, underage wagering, receiving money for bets, and accepting wagers from people physically located in Nevada without a licence. The NGCB simultaneously issued industry guidance requiring licencees to perform due diligence and report jurisdictions where they operate online gaming products.
Key Points
- The NGCB filed a civil enforcement action seeking an injunction to stop Polymarket offering what the Board classifies as unlicensed wagering.
- The complaint cites alleged violations of NRS 463.160, 463.350, 465.086 and 465.092 relating to unlicensed gaming, age restrictions, receipt of betting funds, and taking Nevada-located wagers without a licence.
- Polymarket is likely to try to remove the case to federal court, arguing federal preemption under the Commodities Exchange Act as seen in related cases brought by Kalshi, Crypto.com and Robinhood.
- Previous related litigation: Kalshi previously won a preliminary injunction against Nevada (on preemption grounds) though similar efforts by other firms saw mixed outcomes in federal courts.
- The NGCB issued “Industry Guidance for Online Gaming Protocols,” pressing licencees to complete due diligence and report jurisdictions where they offer online products within 60 days.
Content Summary
The article explains the NGCB’s reasons for suing Polymarket and lists the specific Nevada statutes it alleges Polymarket has breached. It outlines the likely procedural next step — removal to the U.S. District Court for the District of Nevada — where other prediction-market or crypto-exchange defendants have argued federal law preempts state regulation. The story also notes the NGCB’s contemporaneous guidance to Nevada licencees to tighten compliance and disclosure around online offerings.
Context and Relevance
This lawsuit lands amid an ongoing legal battle over whether prediction markets and crypto-enabled exchanges are governed by state gaming laws or federal commodities law. A Nevada ruling against Polymarket could restrict access to prediction markets for Nevada residents and influence regulatory approaches in other states. Operators and licencees across the sector should watch for potential precedent and compliance implications, especially given the NGCB’s new guidance demanding proactive due diligence by licencees.
