Nevada Judge Blocks Kalshi, Escalating Fight Over Prediction Markets

A Nevada judge has temporarily blocked Kalshi from operating in the state, marking a new setback for the prediction market platform as state regulators push back against its event contracts.

Judge Jason Woodbury granted a temporary restraining order that stops Kalshi from offering contracts to Nevada residents without a state license. The order covers contracts tied to sports, elections, and entertainment, according to Reuters. Nevada regulators argued that Kalshi was running an unlicensed sports pool in the state.

Kalshi has argued that its markets fall under federal oversight through the Commodity Futures Trading Commission. However, the Nevada court did not accept that argument at this stage. Instead, the judge said the state could enforce its own gaming laws while the case moves forward.

The ruling adds pressure on Kalshi at a time when the company is already facing legal challenges in other states. Therefore, the Nevada order could shape a broader debate over whether event contracts should be treated as financial products or as gambling.

Nevada says Kalshi contracts violate state gaming law

Nevada’s case against Kalshi did not begin with this order. In February, the Nevada Gaming Control Board sued to stop the company from offering sports related event contracts in the state. That earlier lawsuit set the stage for the latest court fight.

State regulators said Kalshi’s products fit Nevada’s definition of gambling activity that requires a license. As a result, the state asked the court to step in quickly and block the platform before the case reaches a final ruling. Reuters reported that the judge agreed to issue temporary relief.

For now, the court order is temporary, not final. Still, it immediately limits Kalshi’s ability to keep operating in Nevada and gives state regulators an early win in a case that could carry wider implications for prediction markets.

Broader pressure grows as more states challenge Kalshi

Nevada is not the only state taking action. Reuters reported that Kalshi is also facing pressure in Massachusetts, where a judge issued an injunction, and in Arizona, where authorities filed criminal charges accusing the company of operating an illegal gambling business. AP also confirmed that Arizona filed 20 criminal charges.

That wider legal pressure matters because Kalshi has positioned its contracts as federally regulated derivatives rather than gambling products. Yet state regulators are pushing the opposite view. Consequently, the dispute is becoming a direct test of how US law will treat sports, election, and entertainment event contracts.

The next key date in Nevada is April 3, when the court is set to consider whether a longer term injunction should follow. Until then, the temporary block keeps Kalshi out of the state and keeps the larger legal battle in focus.
