A Nevada federal judge declined to keep Kalshi’s lawsuit against state gaming officials, sending the dispute to state court and intensifying the tug-of-war over who can regulate markets built around event outcomes. By remanding for lack of subject-matter jurisdiction, the ruling lets Nevada’s regulator pursue an injunction against Kalshi even though the platform is registered with the CFTC.
State-Law Claims Take Center Stage
Filings show the judge concluded the Nevada Gaming Control Board’s allegations arise under state law and are not entirely displaced by the Commodity Exchange Act. The agency argues Kalshi is effectively running an unlicensed sportsbook by offering contracts tied to sports results—products that make up much of the venue’s activity and resemble sports betting to the state regulator. That line-drawing often turns on whether a product is treated as a consumer wager on a sports outcome or as a cash-settled derivatives contract listed on a federally supervised venue, with regulators weighing factors such as how the contract is marketed, who can access it, and whether it functions more like risk transfer or like wagering on a game.
CFTC’s Reach and the Preemption Question
The dispute also turns on how federal commodities oversight interacts with state gaming enforcement when contracts reference real-world events.
| Regulator | Authority Claimed | Legal Basis | Court Interpretation |
|---|---|---|---|
| Commodity Futures Trading Commission | Exclusive oversight of certain futures and swaps venues, including event-based contracts listed on registered platforms | Commodity Exchange Act | The court did not treat federal oversight as automatically displacing state-law claims in this posture |
| Nevada Federal Court | Authority to assess subject-matter jurisdiction and the scope of federal preemption in the removed case | Federal jurisdiction and preemption principles applied to the Commodity Exchange Act | Read the statute to mean Congress did not intend to wipe out ordinary state rules, leaving Nevada courts to decide whether to halt trading on the challenged contracts |
In practice, the CFTC’s role in this area includes supervising registered venues, reviewing self-certifications, and retaining the ability to scrutinize or challenge certain event contracts—particularly where the agency views offerings as implicating prohibited “gaming” features or other public-interest concerns. At the same time, the scope of preemption remains contested in courtrooms, and the agency’s oversight does not necessarily prevent state regulators from pursuing parallel theories under state gaming laws.
Legal analyst Daniel Wallach called the outcome unsurprising yet consequential, noting it edges Kalshi closer to being sidelined in Nevada—potentially the first state where a court forces the company to stop listing event-based derivatives.
Wallach warned of a cascading effect in other jurisdictions:
- Implementation of geofencing.
- Impact on legal arguments in other jurisdictions.
- Complications in broader regulatory disputes.
In a parallel matter decided the same day, the court refused to move Polymarket’s clash with Nevada to federal court, finding the company was not acting under the CFTC simply by operating an exchange with federal compliance processes and self-certifying contracts. Polymarket quickly sought an emergency stay while it prepares an appeal.
Other disputes have also highlighted the uneven U.S. legal landscape for these products, including earlier fights over CFTC no-action relief for election-related markets such as PredictIt, where the platform’s ability to operate hinged on shifting agency positions and court challenges tied to the boundaries of permissible event contracts.
Kalshi’s next move could be to seek an administrative stay from the Supreme Court to pause the remand while it pursues relief in the Ninth Circuit, aiming to keep trading uninterrupted during the appellate process.
Wallach noted that while the Supreme Court has, at times, issued short administrative stays to maintain the status quo pending circuit review, obtaining one without expedited treatment from the Ninth Circuit may prove difficult.
These twin rulings add fresh ambiguity to the legal footing of markets built on real-world outcomes and to the CFTC’s role in policing them. More broadly, prediction markets in the U.S. operate in a patchwork: some platforms attempt to fit within federal commodities regulation, while state regulators may still challenge the same activity under sports-betting or gaming frameworks, creating overlapping—and sometimes conflicting—enforcement pressure.
Prediction markets are increasingly regulated through overlapping federal and state theories, and that fragmentation can leave even well-resourced operators unsure which rules will be applied, by which regulator, and on what timeline.
Key regulatory challenges include persistent ambiguity over whether particular contracts are treated as gambling or as derivatives, jurisdictional disputes between state and federal regulators, and uncertainty in legal definitions and enforcement standards that can shift from case to case. Market structure also evolves quickly—new contract types, distribution channels, and trading mechanics can outpace the cadence of formal rulemaking and litigation, leaving regulators and courts to apply older categories to newer products.
That uncertainty also creates enforcement risk as the sector grows: operators can face inconsistent approaches across jurisdictions, heightened scrutiny from both state and federal agencies, and incentives for regulatory arbitrage when activity can be routed through different legal or technical structures. The practical consequence can be abrupt changes to product availability, including emergency injunction requests, trading pauses, or contract delistings driven by fast-moving court orders or regulatory demands.
In 2024, Kalshi tried to list Congressional Control Contracts allowing users to speculate on which party would control Congress. Under a different administration, the Commodity Futures Trading Commission moved to block those offerings as gambling related to elections, activity restricted in many states. That episode underscored how political sensitivity can influence regulatory decisions, with election-linked contracts drawing heightened attention based on concerns about integrity, public confidence, and perceived commodification of democratic outcomes.
Kalshi responded with an Administrative Procedure Act challenge, and a federal court in Washington, DC, held that the agency misclassified the contracts as gaming, vacating the decision. The DC Circuit later concluded the CFTC’s asserted risks—market manipulation and threats to election integrity—were speculative and lacked concrete support.
Now confronting the opposite side of the gambling debate, the CFTC again finds its authority curtailed with respect to event-driven derivatives, but this time in a way that favors state-level enforcement over federal preemption.
For practitioners—including platform operators, market makers, and sophisticated participants—the implications are practical as well as legal: potential exposure can attach under multiple overlapping regimes, compliance programs may need to account for both federal commodities expectations and state gaming restrictions, and operational planning can be disrupted by shifting legal interpretations across venues and jurisdictions. The reputational stakes can also be significant, particularly for products tied to sports and elections, where public-facing controversy can move as quickly as the legal process.
