The legal battle over prediction markets in the U.S. has escalated significantly. Kalshi, a major prediction market company, faces mounting pressure from state regulators. In Nevada, a settlement agreement collapsed after state investigators bypassed Kalshi's geofencing system, leading to accusations of bad faith from both sides. Kalshi faces potential daily fines of $120,000. More critically, New York Attorney General Letitia James filed a lawsuit on July 31, alleging Kalshi operates as an unlicensed sports gambling platform in violation of state law, including allowing underage betting. The lawsuit seeks to recover all profits from the alleged illegal operation. Kalshi argues its platform is a prediction market, not a sportsbook, but New York officials assert it is functionally identical to gambling. The company had previously sought a federal injunction to block New York's enforcement, which was denied.

Last month, I wrote about the tug-of-war between the Trump administration and the states over prediction markets. Kalshi, one of the largest U.S. prediction market companies, had just won a favorable ruling from a federal court in Minnesota with the help of a key federal financial regulator. Since then, things have escalated dramatically for the prediction-market industry on multiple fronts.
Nevada: Geofencing Agreement Falls Apart
Nevada, which has extensive experience with gambling regulation, had appeared to strike a bargain with Kalshi earlier this year by getting it to agree to a geofencing restriction. In exchange for blocking people within the Silver State from accessing its markets, the state agreed to drop its ongoing case against the company.
That agreement fell apart last week after investigators for the Nevada Gaming Control Board were able to circumvent the geofencing services used by Kalshi.
Under the terms of the agreement, Kalshi agreed to pay the state $120,000 per day if it failed to implement a geofence by August 12. The company instead lashed out at Nevada regulators by accusing them of providing "falsified information (breaking federal law) to hunt for a loophole and manufacture another legal grievance" against Kalshi.
"This is not the behavior of a regulator trying to protect consumers—it is a vindictive waste of taxpayer dollars at the bidding of casinos," Rick Heaslip, Kalshi's general counsel, claimed on Twitter last week.
The Nevada Gaming Control Board was unamused, to say the least.
"Kalshi's accusations are baseless, and they cannot obscure the fact that Kalshi missed its agreed-upon deadline to comply with Nevada law," the board said in a statement. "Kalshi's consistent failures to comply with the court orders left the board with no other choice but to advise the court of Kalshi's noncompliance."
That could open the door to more punitive sanctions against the company.
New York: State Files Lawsuit Alleging Illegal Gambling
An even greater legal threat emerged in New York after state officials filed a lawsuit against Kalshi on July 31 for allegedly violating the state's gambling laws.
State law requires sports-betting companies to obtain a license from the state gaming commission and pay taxes on their winnings. New York also alleged that Kalshi violated the state's age limit for sports betting by allowing 18, 19, and 20-year-olds to place bets on its marketplaces.
"No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple," New York Attorney General Letitia James said in a statement announcing the lawsuit. "By ignoring our laws, Kalshi is running an illegal operation and harming New Yorkers in the process. We are taking them to court to uphold our laws and protect New Yorkers."
How Kalshi's Sports Contracts Work
Kalshi first announced that it would take bets on sports events in January 2025, the New York lawsuit noted, and advertised its product as allowing users to "view live sports (and bet)."
In practical terms, a Kalshi "sports contract" is functionally no different than a bet to the average consumer:
- A customer places a wager in the form of purchasing sports contracts on a binary outcome
- Examples range from whether the Los Angeles Dodgers will win the 2026 World Series to whether Shohei Ohtani will hit a home run during a specific game
- If the wager is correct, the bettor receives a larger sum payment
Key Difference from Traditional Sportsbooks
The principal difference between a prediction market and a traditional sportsbook is that the counterparty for the wager isn't the company itself, but other bettors who are buying and selling "event contracts." While sportsbooks derive their profit from losing bets by their customers, Kalshi and other prediction markets instead get their revenue from transaction fees for each wager placed.
Timeline of Escalation
- October 2025: New York state officials first instructed Kalshi to cease and desist its unlicensed sports gambling operation
- Three days later: Kalshi sued the state to obtain a preliminary injunction blocking New York from enforcing its demands
- Last month: A federal district court in Manhattan denied those motions
- July 31: The state escalated by filing its own lawsuit seeking to recoup all profits from the operation
