Massachusetts judge allows state regulators to ban Kalshi

Suffolk County Superior Court Judge Christopher Barry-Smith has granted Massachusetts Attorney General Andrea Campbell a preliminary injunction against Kalshi, allowing regulators to enforce a ban on Kalshi’s event contracts.

Campbell filed the lawsuit in September 2025, arguing that prediction market operators must have a betting license to offer event contracts. The suit mentioned that Kalshi makes a bigger percentage of revenue from sports betting than operators like DraftKings and FanDuel do. Additionally, it was noted that Kalshi uses gambling terminology and mirrors other online gambling experiences.

Campbell said:

“Sports wagering comes with significant risk of addiction and financial loss and must be strictly regulated to mitigate public health consequences. This lawsuit will ensure that if Kalshi wants to be in the sports gaming business in Massachusetts, they must obtain a license and follow our laws.”

Many other states have also sued Kalshi for offering prediction event contracts, including Nevada, New Jersey, and Maryland, as lawmakers explain that Kalshi relies on a different interpretation of the Commodities Exchange Act in order to avoid state regulation.

The injunction will go into effect on January 23, 2026; however, Kalshi hasn’t yet commented on or appealed the ruling.
