Nevada has become the first US state to actually force prediction exchange Kalshi to restrict access to its markets, following a court order issued late last week that marks a real escalation in the regulatory battle over event contracts.

Nevada’s First Judicial District Court granted the Nevada Gaming Control Board a 14-day temporary restraining order on Friday, compelling Kalshi to block sports, entertainment and election contracts for users in the state. The order runs through 3 April, when the next hearing is scheduled.

By Saturday, Nevada residents trying to access the restricted categories hit error messages citing the court order. Kalshi’s response was pointed: “We disagree with those restrictions, but as a law-abiding company, we’re following them. We’re confident in our legal position, and we’ll continue to fight for your right to trade the same products that are available in 49 other states.”

Enforcement Victory for Nevada Regulators

The NGCB framed the action as a matter of protecting licensed operators. “The offering of sports event contracts, along with certain other event contracts, constitute wagering activity,” the board stated. Nevada has now “successfully restricted the operation of all unlicensed prediction markets that had been known to be operating in Nevada.” That list includes Polymarket, Robinhood, Coinbase and Crypto.com.

NGCB Chair Mike Dreitzer was blunt about the regulatory position. “Prediction markets, to the extent they facilitate unlicensed gambling, are illegal in Nevada, and we have a statutory duty to protect the public. We want people in the state to wager safely at a licensed book.”

Technical Implementation Raises Questions

The enforcement mechanism itself is quite intriguing. Kalshi has previously argued in court that jurisdictional restrictions contradict federal impartial access requirements for financial markets. They also claimed geofencing technology would be too costly and impractical to put in place.

Despite these assertions, Kalshi appears to have enacted restrictions using customer registration data. Nevada residents are now barred from trading affected contracts regardless of physical location, while out-of-state visitors to Nevada can still access the platform. This represents a departure from the location-based geofencing that sports betting jurisdictions use.

The blocking mechanism isn’t entirely precise, though. Reports indicate some contracts slipped through the net over the weekend. Markets on Saturday Night Live monologues, government shutdown duration and certain political mention markets got through, despite apparent connections to restricted categories. Kalshi declined to comment on the court ruling or its implementation.

Broader Industry Implications

Nevada’s position as America’s pre-eminent gaming jurisdiction makes this action particularly significant.

Similar legal challenges are proceeding in New Jersey, New York and Ohio, and the regulated industry has rallied behind Nevada’s approach.

“We strongly agree with Chairman Dreitzer’s remarks that prediction markets are offering illegal sports wagers in Nevada and applaud the state’s decisive enforcement to uphold its laws, protect its consumers and defend the integrity of its regulated industry,” said Bill Miller, CEO of the American Gaming Association.

The AGA has made prediction markets a central policy issue, enlisting former New Jersey Governor Chris Christie to spearhead messaging efforts. The stance has proven divisive. FanDuel, DraftKings, Fanatics, OpenBet and Sportradar all left the trade group over prediction market ties. The AGA maintains a running tracker alleging prediction markets have diverted over $650 million in potential state sports betting tax revenue.

Timing and Market Pressure

The enforcement push comes as Nevada faces broader economic headwinds. Las Vegas tourism and visitation have lagged for nearly 18 months, even as gaming revenue has held relatively steady. This divergence has raised questions about the sustainability of the state’s hospitality model, making encroachment from unlicensed operators a particularly sensitive issue.

Nevada’s Super Bowl handle of $133.8 million in February marked the lowest figure in a decade. Regulators may view that as evidence of market cannibalisation. Whether prediction markets genuinely contributed to that decline remains debatable, but the timing has certainly sharpened regulatory resolve.

The temporary restraining order runs only through early April. The next hearing will determine whether Nevada’s restrictions become more permanent. For now, Kalshi has complied with the order while signalling its intention to contest the legal position. The outcome will likely shape how other states approach prediction market regulation in an increasingly fragmented market.
