Kalshi, a federally regulated prediction market platform, faces mounting class action lawsuits across multiple states claiming that its betting mechanics violate state gambling laws, despite the company’s registration with the U.S. Commodity Futures Trading Commission. As of January 2026, Kalshi faces 19 federal lawsuits across various states, with litigation accelerating following high-profile legal wins against the platform in Massachusetts and aggressive new legislation in Minnesota.
The core dispute hinges on whether Kalshi’s prediction market activities fall under federal CFTC commodity regulation or whether states retain authority to classify and restrict them as illegal gambling. The legal challenge to Kalshi represents a fundamental conflict in American regulatory authority. While the CFTC has approved Kalshi’s operations as a regulated commodities exchange, plaintiffs argue that prediction markets—particularly those focused on election outcomes and sports events—function identically to illegal gambling in violation of state law. Litigation funder Veridis Management has been strategically driving similar suits in Ohio, Illinois, South Carolina, Massachusetts, and Georgia, signaling a coordinated effort to establish that state gambling prohibitions supersede federal commodity regulation.

How Prediction Markets Function and Why States Question Their Legality
Kalshi operates as a platform where users place bets on the outcomes of future events—elections, economic indicators, sports results, and other occurrences. Unlike traditional stock or commodity exchanges, the underlying product is not ownership or a futures contract on a tangible asset, but rather a binary bet on whether a specific event will or will not occur by a set date. If your prediction proves correct, you profit; if it does not, you lose your stake. From a user perspective, this mechanics mirror traditional gambling more closely than commodity trading. The legal argument against Kalshi centers on the nature of these contracts and their similarity to prohibited wagers. State gambling laws, which vary significantly across jurisdictions, typically criminalize or restrict “gambling” defined as risking money on uncertain outcomes with no underlying economic purpose beyond the bet itself.
Kalshi’s platform, plaintiffs argue, offers exactly this: users do not gain hedging protection, insurance value, or any tangible commodity exposure. They are simply betting money on event outcomes. The Kentucky class action filed in May 2026 explicitly invokes the Statute of Anne, a 18th-century British law that allows losing gambling participants to recover their losses from the operators of illegal gambling arrangements. This legal theory suggests that even if Kalshi operates under federal license, state law may still provide a remedy to users who placed bets that violate local gambling statutes. The distinction between commodity trading and gambling is not merely academic—it determines regulatory authority, licensing requirements, and consumer protections. The CFTC treats Kalshi’s contracts as commodity futures and has approved them under federal commodities law. But state attorneys general and plaintiffs’ lawyers argue that the CFTC’s authority over futures does not preempt state gambling laws, and that an event-betting platform designed to attract casual bettors differs fundamentally from legitimate commodity hedging.
The CFTC vs. State Gambling Law Authority—The Regulatory Collision
The legal foundation of Kalshi’s challenges stems from a regulatory gray area that has not been definitively resolved by courts. The CFTC operates under federal authority to regulate commodity futures, and it has determined that Kalshi’s prediction contracts qualify for regulation as commodities rather than gambling. However, states also possess independent police powers to regulate gambling within their borders, and this state authority has never been clearly subordinated to federal commodity regulation on the specific issue of prediction markets. This collision of authorities creates a dangerous situation for Kalshi users and the company itself. In Massachusetts, a Suffolk County Superior Court issued a preliminary injunction in January 2026 ordering Kalshi to cease allowing in-state users from placing sports-related bets without a license.
This is striking because it represents a state court directly limiting the operations of a federally regulated platform. Washington state similarly sued Kalshi as of March 28, 2026, joining a growing number of states asserting that prediction market betting violates their gambling statutes regardless of federal commodity registration. If these state victories continue, they could effectively render Kalshi’s federal license meaningless in key markets, forcing the company to either geofence entire states or fight costly litigation in every jurisdiction. The limitation here is critical: the CFTC’s authority is not unlimited, and courts could ultimately determine that state gambling laws take priority. Kalshi users in states with active litigation now operate in legal uncertainty, with no assurance that their bets will be honored or that the platform will continue operating in their states. This uncertainty should weigh heavily on anyone considering significant financial commitments to prediction markets.
The Wave of State Lawsuits and Coordinated Legal Pressure
The litigation against Kalshi has accelerated dramatically in the past six months. Beyond the Massachusetts preliminary injunction and Washington’s state-level lawsuit, Kentucky filed a class action suit on May 11, 2026, explicitly seeking recovery of prediction market gambling losses under state law. This Kentucky litigation is significant because it moves beyond regulatory challenges and directly targets recovery of user losses—the same mechanism that made litigation against traditional online gambling platforms so consequential. What stands out in this litigation landscape is the role of Veridis Management, a litigation funder that has been strategically backing similar suits in multiple states. The presence of an institutional funder signals that this is not a scattered collection of lone plaintiffs, but rather a coordinated campaign to establish legal precedent that prediction market betting violates state gambling laws. By pursuing simultaneous suits in Ohio, Illinois, South Carolina, Massachusetts, Georgia, and Kentucky, Veridis is essentially creating a pressure campaign that forces Kalshi to defend itself across numerous jurisdictions simultaneously.
This strategy mirrors how plaintiffs’ bars have handled other emerging technologies that operate in regulatory gray areas. Kalshi has fought back by filing its own federal lawsuit. When Minnesota Governor Tim Walz signed SF4760 into law on May 18, 2026—making prediction market operation a felony within Minnesota—Kalshi immediately filed a federal suit challenging the ban as unconstitutional. This escalation underscores how high the stakes have become. Kalshi is now not just defending against private class actions, but fighting state legislatures determined to criminalize its core business model. The company argues that Minnesota’s felony law violates interstate commerce protections and federal preemption doctrines, but the outcome remains uncertain.
The Statute of Anne and the Recovery Mechanism for Bettors
One of the most intriguing legal theories in the Kalshi litigation is the invocation of the Statute of Anne, an 18th-century English law that has survived in various American state statutes. The Kentucky class action explicitly relies on this principle, which holds that a person who loses money in an illegal gambling arrangement can recover those losses from the operator of the illegal gaming activity. This is not a damages claim for fraud or misrepresentation—it is a straight recovery of lost betting capital. The appeal of the Statute of Anne to plaintiffs is obvious: if courts agree that Kalshi’s prediction markets constitute illegal gambling under state law, then the statute provides an automatic, dollar-for-dollar recovery mechanism. Users would not need to prove they were deceived or that Kalshi operated recklessly. They would simply need to establish that they placed bets on Kalshi, that such bets violated state gambling law, and that they lost money.
The burden shifts to Kalshi to defend the legality of its operations. For a class action, this could aggregate to significant liability if tens of thousands of users in a single state lost money on the platform. However, there is a major limitation to this recovery strategy. Not all states have adopted the Statute of Anne or its principle. Some jurisdictions have explicitly rejected it, viewing it as an outdated doctrine inconsistent with modern consumer protection law. Moreover, even in states that recognize the principle, courts may find that Kalshi’s federal CFTC registration creates a safe harbor, arguing that federal regulation should supersede invocation of antique English law. The outcome may depend heavily on the specific wording of each state’s gambling statutes and the sophistication of the judicial reasoning in early test cases.
Minnesota’s Felony Law—The Nuclear Option in Prediction Market Regulation
Minnesota’s recent decision to criminalize prediction market operation represents a dramatic escalation in state resistance to Kalshi and similar platforms. Governor Tim Walz signed SF4760 on May 18, 2026, making it a felony to operate a prediction market within Minnesota without specific licensing. This is not a civil fine or regulatory restriction—it is a criminal law that could result in prosecution and imprisonment for company executives and employees facilitating bets in the state. The Minnesota legislation is significant because it signals that states are abandoning nuanced regulatory approaches in favor of outright prohibition. Rather than seeking to license and regulate prediction markets the way many states do with traditional sports betting, Minnesota chose total criminalization except under state-issued licenses that the legislation makes effectively impossible to obtain. This approach mirrors how states have historically treated unlicensed gambling operations.
By criminalizing the activity itself rather than just restricting it, Minnesota created the strongest possible deterrent to Kalshi’s continued presence in the state. Kalshi’s immediate federal lawsuit challenging the Minnesota law highlights the company’s conviction that the legislation violates constitutional limits on state power. Kalshi’s argument likely emphasizes interstate commerce protections—that Minnesota cannot unilaterally prohibit a federally regulated activity that residents may lawfully engage in from other states. However, Minnesota may counter that it has traditional authority to regulate gambling within its borders and that Kalshi’s platform, regardless of federal designation, functions as gambling and thus falls under state authority. The outcome of this constitutional challenge could redefine the scope of state power over prediction markets nationwide. If Kalshi wins, it establishes that federal commodity regulation preempts state gambling bans. If Kalshi loses, it signals that states can essentially opt out of prediction markets through criminalization.
Implications for Kalshi Users and Potential Class Action Plaintiffs
If you have placed bets on Kalshi, the ongoing litigation creates real financial and legal uncertainty. In states where class actions have been filed or where preliminary injunctions have been issued, your bets may be at legal risk. Courts could eventually order Kalshi to return your wagered funds if they determine that the bets violated state gambling law, which sounds positive until you realize that such a ruling would also render your potential winnings unenforceable. In other words, you might recover your losses but lose any profits you had made.
The practical implication is that Kalshi users in active litigation states should carefully track the status of cases in their jurisdiction. A preliminary injunction, like the one Massachusetts issued in January 2026, is a temporary measure that can signal how a court is likely to rule on the full merits. If a state court has already signaled skepticism toward Kalshi’s operations, the risk of using the platform in that state increases significantly. Users should also be aware that class action membership is often automatic for anyone who held an account during the relevant period, meaning you could be bound by a settlement even if you did not actively participate in the lawsuit.
The Future of Prediction Markets and Regulatory Clarity
The Kalshi litigation is likely to continue escalating through 2026 and beyond, with multiple paths to resolution. Some cases will be decided on their merits by state and federal courts, potentially reaching appellate level if constitutional questions are raised. Others may be settled by Kalshi in exchange for geographic restrictions or operational changes. Minnesota’s federal challenge to the state’s felony law will be particularly influential; a federal court ruling on the constitutionality of state prediction market bans would effectively set the regulatory ceiling for the entire industry.
What is increasingly clear is that prediction markets are becoming a contested terrain between federal and state authority. Congress could intervene to clarify the regulatory framework, either endorsing Kalshi’s federal licensing model or explicitly deferring to state gambling law. Until that happens, the status quo is litigation, with states asserting authority over activities that the CFTC has already approved. This conflict will not be quickly resolved, and it ensures that prediction market platforms and their users will operate in legal uncertainty for at least the next several years.
Conclusion
Kalshi’s prediction market platform faces a direct challenge: 19 federal lawsuits and state-level legal action that question whether the company’s activities constitute illegal gambling regardless of CFTC registration. The case hinges on a fundamental regulatory conflict between federal commodity law and state gambling authority, with states increasingly asserting that prediction market betting violates their gambling statutes. Litigation funders like Veridis Management are coordinating multi-state campaigns, Minnesota has criminalized the activity entirely, and courts have already issued preliminary injunctions limiting Kalshi’s operations in certain jurisdictions.
If you have participated in prediction markets or are considering doing so, monitor developments in lawsuits filed in your state and understand that the legal status of these platforms remains unsettled. The Statute of Anne and other recovery doctrines may allow users to recover losses if courts determine that prediction markets violate state gambling law. The outcomes of key cases—particularly Kalshi’s constitutional challenge to Minnesota’s felony law and the Massachusetts injunction on its merits—will likely determine the future of the industry and the extent to which states can regulate or prohibit prediction market betting within their borders.
Frequently Asked Questions
Is Kalshi legal?
Kalshi is registered with the CFTC as a regulated commodities exchange, but its legality is disputed in multiple state lawsuits. Courts in Massachusetts have issued preliminary injunctions limiting Kalshi’s operations, and numerous states argue that prediction market betting violates state gambling laws despite federal registration.
Can I recover my losses from Kalshi?
If you live in a state where a class action has been filed, you may be automatically included as a class member. Some lawsuits invoke the Statute of Anne, which allows recovery of gambling losses if courts determine the bets violated state law. However, recovery is not guaranteed and depends on the outcome of ongoing litigation.
Why did Minnesota make prediction markets a felony?
Minnesota’s Governor signed SF4760 in May 2026, making prediction market operation a felony without state licensing. The state argued that prediction markets function as gambling and should be criminalized like unlicensed gambling operations. Kalshi has challenged the law as unconstitutional.
What is the Statute of Anne?
The Statute of Anne is an 18th-century English law, adopted in various forms by American states, that allows someone who loses money in illegal gambling to recover those losses from the operator. Kentucky’s class action invokes this principle to seek recovery for Kalshi users.
How many lawsuits does Kalshi face?
As of January 2026, Kalshi faced 19 federal lawsuits across multiple states. Additional litigation has been filed since then, including in Kentucky (May 2026) and Washington state (March 2026).
What happens if Kalshi loses in court?
If courts determine that prediction market betting violates state gambling laws, Kalshi could be forced to cease operations in those states, refund user losses, and potentially face criminal liability. The company could also be restricted from operating nationwide if federal courts rule against it in constitutional challenges.
