After Kalshi appeal, prediction markets fight could head to US Supreme Court

An appellate court is expected to reach a decision after hearing arguments from Kalshi and lawyers representing the state of Nevada.

Some legal experts speculated that the state vs. federal jurisdiction battle over regulating prediction markets companies could soon be headed to the United States Supreme Court.

On Thursday, the US Court of Appeals for the Ninth Circuit heard oral arguments from lawyers representing prediction markets platform Kalshi and Nevada authorities over the state's ban on the prediction markets' event contracts. The appeal was over a lower court decision preventing Kalshi from offering certain event-based contracts in Nevada, based on claims that the company needed a gaming license.

The appellate judge overseeing Thursday’s oral arguments and the lawyer for Kalshi acknowledged that there had been several state-level enforcement actions against the company and other prediction market platforms, including criminal charges filed in Arizona. However, last week a federal court blocked Arizona authorities from enforcing the state’s gambling laws on Kalshi’s event contracts.
