A Nevada judge temporarily blocked Kalshi from operating in the state after regulators argued the federally regulated prediction market was offering unlicensed sports wagering. The dispute, which intensified in February and March 2026, now sits at the center of a broader state-versus-federal fight over who controls event-contract trading tied to sports and other outcomes. For readers, the key questions are immediate: what the court did, why Nevada says Kalshi must stop, what Kalshi argues in response, and what comes next in both state and federal proceedings.
Nevada regulators sought emergency relief after a federal remand order on March 2, 2026, and a court filing on March 9 said the state was entitled to a temporary restraining order barring Kalshi from operating markets that Nevada treats as unlawful gaming activity, according to documents posted by the Nevada Gaming Control Board. The legal clash follows Nevada’s March 4, 2025 cease-and-desist order and a separate Ninth Circuit appeal scheduled for oral argument on April 16, 2026, according to Nevada court filings and the federal remand order.
⚠️
The Nevada case is no longer just about a cease-and-desist letter.
By February 17, 2026, the Nevada Gaming Control Board had filed a civil enforcement action seeking to halt Kalshi’s in-state operations until it obtained a Nevada gaming license and complied with state gaming laws, according to the March 2 federal remand order.
March 2026 filings put Kalshi’s Nevada access at risk
The immediate trigger for the latest court action is procedural but consequential. After Kalshi removed Nevada’s enforcement case to federal court, U.S. District Judge Miranda M. Du determined on March 2, 2026 that the federal court lacked subject-matter jurisdiction and remanded the matter to state court, according to the filed order. Nevada then moved quickly to pursue emergency relief against Kalshi’s operations.
In an ex parte motion filed March 9, 2026, Nevada told the court that Kalshi had been “willfully circumventing” Nevada law and asked for a temporary restraining order prohibiting the company from operating a market that accepts what the state characterizes as wagers without Nevada gaming licenses. The filing also said Nevada sought to stop Kalshi from allowing persons under age 21 in Nevada to participate, a point that underscores the state’s argument that these contracts function like sports betting rather than conventional financial hedges.

Why Nevada says federally listed contracts still violate state law
Nevada’s position is direct: if a product looks and functions like sports wagering inside the state, it must comply with Nevada’s gaming framework. In the March 4, 2025 cease-and-desist order, the Nevada Gaming Control Board said Kalshi was offering event-based contracts that, in the board’s view, constituted unlawful activity in Nevada and ordered the company to stop by 5:00 p.m. on March 14, 2025. That deadline marked the first major escalation in the dispute.
By February 2026, Nevada had sharpened that argument in court. The March 2 remand order states that the board’s complaint alleges violations of Nevada Revised Statutes sections 436.160, 463.350, 465.086 and 465.092, while seeking declaratory and injunctive relief under sections 463.343, 463.346 and 30.030. Those citations matter because they show Nevada is grounding the case in state gaming and anti-cheating laws rather than asking a court to reinterpret federal commodities law in the first instance.
Nevada-Kalshi timeline
March 4, 2025: Nevada issues a cease-and-desist order to Kalshi, saying the company must halt allegedly unlawful activity in the state by March 14, 2025.
March 28, 2025: Kalshi files suit in federal court seeking relief against Nevada regulators, according to later court orders.
November 24-25, 2025: The preliminary injunction is dissolved, and Kalshi appeals to the Ninth Circuit, according to the remand order and appellate filings.
February 17, 2026: Nevada files a civil enforcement action to block Kalshi’s in-state operations until it obtains a Nevada gaming license.
March 9, 2026: Nevada files an ex parte motion for a temporary restraining order after the federal remand fight.
How the federal-state split created the latest court clash
Kalshi’s core argument has been that its event contracts fall under the exclusive jurisdiction of the Commodity Futures Trading Commission, not state gaming regulators. That position has kept the company in court across multiple states. In Nevada, Kalshi told the Ninth Circuit in a February 11, 2026 emergency motion that forcing it to cut off Nevada users would impose “millions of dollars” in unrecoverable compliance costs and create conflicts with CFTC-mandated access rules, according to the filing posted by Nevada regulators.
Nevada answered that the company had continued to expand while the appeal was pending. In a February 6, 2026 letter filed with the Ninth Circuit on February 10, the state said Kalshi had “massively increased” trading volumes and marketed sports trading as “100% legal” in all 50 states. Nevada cited a Yahoo Sports report saying Kalshi’s Super Bowl trading volume was nearly 20 times higher than the prior year, using that growth to argue that each day of continued operation caused irreparable harm to the state, licensed operators and the public interest.

Volume growth became part of Nevada’s legal argument.
Nevada told the Ninth Circuit that Kalshi’s Super Bowl trading volume was nearly 20 times the prior year, citing Yahoo Sports in a February 6, 2026 letter filed on February 10. The state used that figure to argue the company was expanding, not preserving the status quo.
What the Nevada order means for Kalshi and the wider prediction market fight
The Nevada action matters beyond one state because it tests whether a federally regulated prediction market can keep offering sports-linked contracts where state regulators say those products amount to unlicensed gambling. Associated Press reported on February 17, 2026 that a federal judge in Nevada had agreed with the Nevada Gaming Control Board and issued a temporary restraining order against Kalshi operating in the state, while judges in New Jersey and Tennessee had ruled in Kalshi’s favor in separate disputes. That split shows there is no single national answer yet.
For Nevada, the significance is economic as well as legal. The state has one of the most established gaming regulatory systems in the U.S., and its filings argue that Kalshi’s contracts bypass licensing, age-gating and integrity controls imposed on traditional sportsbooks. For Kalshi, the stakes are operational and strategic: Nevada is a marquee gaming jurisdiction, and an adverse ruling there could influence how other states frame enforcement actions. That is an inference based on the breadth of state litigation and the prominence of Nevada’s gaming regime.

April 16 appeal date is the next major checkpoint
The next date on the calendar is April 16, 2026. That is when the Ninth Circuit is scheduled to hear oral argument in Kalshi’s appeal, according to the March 2 remand order. The appeal is separate from Nevada’s state-court enforcement push, but the issues overlap because both turn on whether federal commodities regulation displaces Nevada’s authority over these contracts.
Until then, the practical effect of the Nevada judge’s temporary block is straightforward: Kalshi faces immediate limits on operating in the state while the legal fight continues. The broader policy question remains unresolved. States argue they are policing gambling within their borders. Kalshi argues it lists federally regulated event contracts. Courts are now deciding where one regime ends and the other begins.
Frequently Asked Questions
Why did Nevada move to block Kalshi?
Nevada says Kalshi’s sports-linked event contracts amount to unlicensed wagering under state law. In filings dated February 17 and March 9, 2026, the Nevada Gaming Control Board sought declaratory and injunctive relief, including a temporary restraining order, until Kalshi obtains a Nevada gaming license and complies with state rules.
When did the dispute between Nevada and Kalshi begin?
The public dispute began on March 4, 2025, when the Nevada Gaming Control Board issued a cease-and-desist order directing Kalshi to stop the activity Nevada considered unlawful by March 14, 2025. Kalshi later sued in federal court on March 28, 2025, according to subsequent court orders.
What is Kalshi’s main legal argument?
Kalshi argues that its event contracts are regulated by the Commodity Futures Trading Commission and that state enforcement is preempted. In a February 11, 2026 emergency motion, Kalshi said cutting off Nevada users would create major compliance costs and conflict with federal access obligations.
Is Nevada the only state challenging Kalshi?
No. Associated Press reported on March 17, 2026 that Nevada and Massachusetts had early rulings favoring state restrictions, while federal judges in New Jersey and Tennessee had ruled in Kalshi’s favor. Arizona also escalated the fight with criminal charges announced March 17, 2026.
What happens next in the Nevada case?
A major next step is the Ninth Circuit oral argument scheduled for April 16, 2026, according to the March 2 remand order. Separately, Nevada’s state-court enforcement action continues, meaning Kalshi’s ability to operate in Nevada may depend on both appellate and state-level rulings.
