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

The 6th ​US Circuit Court of ⁠Appeals ⁠said Kalshi ​has not shown that ​its sports event contracts ‌are “swaps” that should be regulated exclusively ⁠by the federal Commodity Futures Trading ⁠Commission. ‌It also ⁠said federal ​law ‌did not ​preempt Ohio’s ⁠or Tennessee’s gambling laws.
