Ohio regulators are ramping up pressure on prediction market platform Kalshi, proposing a $5 million penalty and accusing the company of running illegal sports gambling in the state.
In a letter dated April 14, 2026, the Ohio Casino Control Commission told Kalshi it has the “intent to impose a penalty or fine for operating or conducting unlicensed sports gaming in Ohio,” according to a document shared publicly by Ohio Attorney General Dave Yost. The notice also gives Kalshi the option to request a hearing.
Yost wrote that the state views Kalshi’s event contracts as unlawful bets and suggested the company’s time operating in Ohio could be limited.

This latest move adds to a drawn-out legal fight between Kalshi and Ohio officials over how prediction markets should be regulated. State regulators have repeatedly argued that contracts tied to sports outcomes look and function like traditional sports betting. Because of that, they say, companies offering them need proper licensing under Ohio law. Officials have also warned other platforms with similar products that they could be violating the state’s gaming system.
Kalshi has pushed back, maintaining its contracts are federally regulated financial instruments overseen by the Commodity Futures Trading Commission, not wagers controlled by state gambling authorities. The company has taken the issue to court, filing a federal lawsuit challenging Ohio’s stance.
So far, the legal battle has produced mixed results. A federal judge in Ohio refused Kalshi’s request to block enforcement, allowing the state to continue its actions while the case moves forward, giving regulators an early advantage.
Kalshi has since continued to fight, appealing parts of the case in an effort to keep operating in Ohio during the litigation. Meanwhile, the state has stayed aggressive, opposing those appeals and defending its authority in higher courts.
Multiple states are currently grappling with how to handle prediction markets, and the outcomes have been inconsistent. New Jersey has acted to restrict Kalshi, influenced in part by earlier enforcement efforts in Nevada.
At the same time, some court decisions elsewhere have supported Kalshi’s position. An appeals court ruling involving Arizona suggested federal law may override certain state restrictions, strengthening the company’s argument.
