The legal war over prediction market sites just hit a new level. Kalshi, the federally regulated trading exchange that’s become the face of event-based betting in America, is suing the New York State Gaming Commission (NYSGC).
The company claims the state overstepped its authority after issuing a cease-and-desist order that could have forced Kalshi to halt operations immediately.
The Spark That Lit the Fire
The drama started on Friday, October 24, when the NYSGC sent Kalshi a cease-and-desist letter accusing the company of offering unlicensed sports wagering within the state.
The letter alleged Kalshi was “illegally operating, advertising, and promoting” a mobile sports betting platform and threatened fines and civil penalties if the company didn’t immediately stop.
Just two days later, Kalshi fired back. The company filed a lawsuit in Manhattan’s US District Court, arguing that the NYSGC’s threats violated federal law. Kalshi’s team says the Commodity Futures Trading Commission (CFTC)—not state regulators—has exclusive oversight over its operations.
In short, Kalshi believes its event contracts are legitimate financial products regulated at the federal level, not gambling activities governed by state law.
In the filing, Kalshi stated that “defendants have implicitly threatened Kalshi with criminal action and explicitly threatened Kalshi with civil penalties, including fines, unless it shuts down these contracts in New York immediately.”
The lawsuit asks the court for an emergency order to stop the NYSGC from enforcing its cease-and-desist directive.
Why Kalshi Says It’s Protected
Kalshi’s argument hinges on federal preemption. The company claims that when Congress created the CFTC, it intended to prevent a messy patchwork of 50 different state rules from interfering with national trading markets.
Under the Commodity Exchange Act, exchanges like Kalshi are classified as “Designated Contract Markets,” which gives the CFTC full regulatory authority over their operations. According to Kalshi, that means state regulators—including the NYSGC—have no jurisdiction.
The company emphasized this point in the lawsuit, saying, “One of Congress’s avowed goals in creating the CFTC was to avoid the chaos that would result from subjecting exchanges to a patchwork of 51 different—and potentially conflicting—state laws.”
Kalshi believes New York’s attempt to regulate event-based contracts “intrudes upon the federal regulatory framework” and would not only harm its operations but also affect partners like Robinhood Markets that rely on its platform.
New York’s View: It’s Gambling, Not Trading
The NYSGC, however, sees things very differently. The cease-and-desist letter defines Kalshi’s offerings as “sports wagering within the meaning of New York law.”
The state contends that customers are staking something of value—money—on the outcome of sporting events, which squarely qualifies as gambling under its regulations.
According to the letter, Kalshi’s activity fits New York’s Penal Law §225.00(2), which classifies betting on “a contest of chance or future contingent event not under one’s control” as gambling.
The commission claims it has the power to “levy and collect civil penalties and fines in connection with Kalshi’s prior, current, and any future activity related to sports wagering.”
In simple terms, New York isn’t buying the argument that Kalshi’s event contracts are financial instruments. To state regulators, they look a whole lot like bets—just dressed up in a different language.
A Pattern of Pushback
This isn’t Kalshi’s first legal fight with state regulators. New York is the eighth state to issue a cease-and-desist notice against at least one prediction market operator, joining Arizona, Illinois, Maryland, Montana, Nevada, New Jersey, and Ohio.
Kalshi has already taken similar action in several of those states, filing lawsuits in federal courts to stop enforcement. Courts in both Nevada and New Jersey even granted Kalshi preliminary injunctions, preventing regulators from interfering with the company’s federally authorized contracts.
The pattern suggests that prediction markets are now in the same gray zone that daily fantasy sports and social sportsbooks once occupied a decade ago—stuck between gambling laws written for another era and a rapidly evolving digital marketplace.
Why the Timing Matters
Kalshi’s lawsuit landed at a crucial moment. Within days of the filing, two major developments reshaped the broader landscape.
First, DraftKings announced it had acquired Railbird Technologies, a CFTC-regulated platform operating under rules similar to Kalshi.
DraftKings plans to launch “DraftKings Predictions,” allowing users to trade on real-world outcomes such as politics, pop culture, and finance. While sports-related contracts haven’t been confirmed yet, the company said expansion is possible.
Second, FanDuel’s parent company, Flutter, is working with the Chicago Mercantile Exchange (CME Group) to create a joint venture called FanDuel Markets.
This new entity plans to offer “event-based contracts with defined risk” through CME’s federally regulated exchange.
With two of the biggest names in American gambling entering the prediction market arena, regulators are now racing to figure out where these platforms fit within the existing legal framework.
The Bigger Picture: State vs. Federal
At its core, Kalshi’s lawsuit against New York asks a simple but consequential question: Who should regulate prediction markets—states or the federal government?
The CFTC has historically treated event contracts as legitimate financial products, primarily when they’re based on measurable, non-sporting outcomes like inflation rates or election results.
Sports, though, complicate things. When the outcome involves a game, state regulators see it as gambling, not trading.
The Federal Showdown That Could Define Prediction Markets
Kalshi is seeking a temporary restraining order and preliminary injunction to block New York from enforcing its cease-and-desist notice. If granted, the company could continue operating while the case plays out.
Legal experts expect the case to hinge on how the court interprets the scope of the CFTC’s authority under the Commodity Exchange Act.
A ruling in Kalshi’s favor would reinforce federal dominance over prediction markets, potentially setting a precedent that limits state control.
A loss, on the other hand, could open the door for states to regulate—or even ban—these markets altogether.
What It All Means for the Future of Trading and Sports Betting
Kalshi’s legal gamble is bold, but it might be the only way forward. The company has made clear it intends to defend its status as a federally regulated exchange, even if that means fighting state by state.
New York’s response will likely set the tone for future battles. If the court sides with Kalshi, prediction markets could gain the legitimacy they’ve been fighting for. If not, the industry could face a wave of new restrictions, fines, and shutdowns.
Either way, the outcome won’t just affect one company. It will define whether Americans can continue to legally “trade” on real-world events—or if prediction markets will be forced back into the shadows of regulation once again.
