Sept 25 (Reuters) – A US appeals court on Friday ruled against the prediction markets operator Kalshi, saying Ohio ​and Tennessee can regulate its so-called ‌event contracts under their gambling laws.

The decision by the 6th US Circuit Court of Appeals in Cincinnati deepens a split among federal appeals ‌courts ​over whether states or ⁠the federal Commodity ⁠Futures Trading Commission has authority to regulate the fast-growing industry.

Kalshi did not immediately respond to requests for comment.

Prediction markets are ​best known for letting people wager on the outcomes of sports events, ⁠though people can also ⁠wager on a wide variety ​of subjects including elections, the weather and ​cultural events such as the Oscars.

Circuit Judge ‌Julia Smith Gibbons wrote for a unanimous three-judge panel that Kalshi did not show that its sports event contracts ⁠were “swaps” that should be regulated exclusively by the CFTC. She also said the federal Commodity Exchange ⁠Act ‌did not preempt Ohio’s or ⁠Tennessee’s gambling laws.

Many states including Ohio ​and ‌Tennessee, which are both Republican-controlled, ​have sought ⁠to crack down on prediction markets, putting them at odds with Republican President Donald Trump’s administration, as well as the CFTC.
