Connecticut's attorney general filed suit against online prediction platform Kalshi on Thursday, alleging the company runs an unlicensed sports gambling operation in violation of state consumer protection laws, the latest in a growing wave of state legal challenges against the fast-growing market.
Attorney General William Tong announced the lawsuit, which targets contracts Kalshi offers on sporting outcomes, including how many wins a team will rack up in a season, the number of points scored in a game, and the points spread. The state's Office of the Attorney General said Kalshi "offers sports event contracts that resemble sports wagers" and put the matter bluntly: "This is gambling."
Tong framed the fight as one of basic consumer protection, not regulatory turf. ABC News reported his statement:
"Sports event contracts are no different than sports betting and are not magically shielded by federal law from Connecticut's commonsense consumer protection laws."
Kalshi fired back immediately. Jovy Dedaj, the company's head of litigation, posted on X that the lawsuit proves states are acting arbitrarily rather than protecting consumers.
"This is the latest in a line of arbitrary and inconsistent enforcement by the states, which shows this has nothing to do with consumer protection. If it did, the states would be seeking the same relief across the board. This unequal treatment is exactly why federal oversight is necessary."
At the center of this legal fight sits a straightforward question: Is a contract on how many points the Celtics score in Game 3 a financial instrument or a sports bet? The answer determines who gets to regulate it, and whether companies like Kalshi can operate freely across all fifty states.
Kalshi says it is regulated as a Designated Contract Market, a type of financial exchange designated to trade futures, swaps, and options on commodities, subject to oversight by the Commodity Futures Trading Commission. That federal designation, the company argues, puts it beyond the reach of state gambling regulators.
Connecticut disagrees. And the state did not wait for the courts to sort it out. Back in December, a Connecticut consumer protection agency ordered Kalshi and two other unnamed platforms to cease and desist from conducting unlicensed online gambling, specifically sports wagering. Kalshi responded by suing Connecticut, seeking to pause the state's enforcement action on the grounds that its contracts fall under exclusive federal jurisdiction.
That effort failed. A federal judge denied Kalshi's motion to pause the legal action earlier this month. Kalshi has appealed the ruling, but Connecticut pressed ahead with Thursday's lawsuit anyway.
The pattern playing out in Connecticut mirrors a broader state-level push to bring prediction markets under gambling statutes. And Kalshi is losing ground on multiple fronts.
Connecticut is not acting alone. A federal court last month temporarily blocked Minnesota's proposed ban on prediction markets, siding with defendants who argued they were subject to federal rather than state oversight. That ruling gave Kalshi a brief win, but the relief was narrow and temporary.
Kalshi spokesperson Elisabeth Diana issued a statement after the Minnesota reprieve that captured the company's core legal theory:
"Today's decision makes it clear: States cannot ban things that they don't have jurisdiction over. It runs directly against what Congress intended when it gave explicit, exclusive jurisdiction over financial markets to federal regulators, and it hurts the traders and everyday citizens who rely on these markets."
Days after that Minnesota decision, however, New York sued Kalshi, alleging its prediction market constitutes illegal, unlicensed gambling, in large part because the state says outcomes depend more on chance than skill.
So Kalshi won a temporary reprieve in one state and immediately got hit with lawsuits in two others. That is not a company on a winning streak. That is a company watching state attorneys general coordinate a legal siege.
The Minnesota federal court ruling may have given Kalshi a talking point, but it did not stop the enforcement wave. And the legal question at the heart of all these cases, whether federal commodity-market oversight preempts state gambling laws, remains unresolved.
Kalshi's strongest rhetorical punch came from Dedaj, who accused Connecticut and other states of singling out his company while allowing other prediction markets to operate undisturbed. If consumer protection were the real motive, he argued, states would pursue the same relief against every platform offering similar contracts.
That claim raises a fair point. Connecticut's December cease-and-desist order targeted Kalshi and two other platforms, but the names of those other companies have not been disclosed publicly. Whether those platforms faced the same escalation Kalshi now confronts, a full-blown state lawsuit, remains unclear.
The selective-enforcement argument also carries weight in a broader regulatory context. Prediction markets have operated in various forms for years. The Ninth Circuit recently sided with Nevada against prediction markets in a ruling that could tee up a Supreme Court showdown over whether these platforms are gambling operations or financial exchanges. If the highest court takes the case, it would settle the jurisdictional fight once and for all.
Until then, Kalshi faces a patchwork of state-level enforcement actions, each one requiring expensive litigation and each one carrying the risk of an unfavorable precedent. The company's appeal of the Connecticut federal judge's ruling adds another layer of legal exposure.
And the platform's own internal governance challenges have not made the public case for self-regulation any easier.
Kalshi's federal preemption argument has a certain legal logic. Congress did grant the CFTC authority over designated contract markets. And there is a legitimate debate about whether state gambling regulators should be able to override that federal framework.
But logic and litigation are two different things. Right now, Kalshi is fighting on at least three state fronts, Connecticut, New York, and Minnesota, while the federal courts have not delivered a definitive ruling in its favor. The Minnesota reprieve was temporary. The Connecticut motion to pause enforcement was denied. And New York's lawsuit adds yet another theory of liability: that outcomes depend on chance, not skill.
For Connecticut's part, the state is not making a complicated argument. Tong's position is simple: if a consumer pays money and wins or loses based on the outcome of a sporting event, that is a sports bet. Calling it a "sports event contract" does not change what it is. And operating without a state gambling license while offering those bets violates Connecticut law.
Kalshi can call its products financial instruments. State attorneys general can call them sports bets. The courts will decide who is right. But the direction of the enforcement trend is clear: states are not waiting for Congress or the Supreme Court to draw the line. They are drawing it themselves.
When a company has to explain to three different state courts why its product is not what it obviously looks like, the regulatory label on the tin matters a lot less than what is inside it.
