Yost and 35 other U.S. Attorneys General oppose betting app

U.S. & Mahoning Valley - Ohio Attorney General Dave Yost along with 35 other U.S. Attorneys General have formed a coalition against Kalshi for what they believe to be the creation of a loophole for unregulated gambling.
"States rightfully have the ability to protect their citizens from the negative consequences of online gambling, no matter how it's packaged," Yost said. "We're protecting the unprotected."
In an amicus brief, the coalition looks towards the U.S. Court of Appeals for the Third Circuit to side with New Jersey in a lawsuit involving mobile app Kalshi.
New Jersey Federal Courts sided with Kalshi in a lawsuit against the New Jersey Division of Gaming Enforcement on April 28, 2025, according to Holland & Knight.
Kalshi labels itself a exchange and prediction market that offers event contracts, which allows users to bet on the outcome of events such as sports championships, political elections and more.
According to Holland & Knight, the company claims that its practices are governed by the Commodity Exchange Act. Event contracts are a contentious topic in legality as many believe it to be gambling.
Other countries, such as the United Kingdom classify and regulate event contracts under gambling.
The brief goes on to warn about the side effects of letting Kalshi get away with what the coalition believes to be unregulated gambling.
"Eliminating the states' ability to regulate online sports betting would pose very serious risks to the states' citizens," the brief says. "Online sports betting, while convenient and entertaining for many, comes with life-altering consequences for some."
Yost and the coalition of attorney generals join the American Gaming Association, the Casino Association of New Jersey and more that are going against Kalshi in the wake of the that April 28 court decision.
