Court Rejects Kalshi's 'Swap' Argument

A federal appeals court in the 9th Circuit ruled against Kalshi, stating that its sports-related event contracts constitute gambling and are not federally regulated "swaps." This decision allows the state of Nevada to apply its gaming laws to Kalshi's prediction market activities.

Kalshi had argued that its sports event contracts were designated contract markets under the Commodity Exchange Act (CEA) and thus fell under the exclusive regulatory authority of the Commodity Futures Trading Commission (CFTC), preempting state laws.

Nevada's Stance Affirmed

The Nevada Gaming Control Board welcomed the ruling, stating that the 9th Circuit "emphatically reject[ed] the view that the federal Commodity Exchange Act preempts application of Nevada’s gaming laws to sports-event contracts offered by Kalshi, Crypto.com, and Robinhood." Nevada Governor Joe Lombardo affirmed that prediction markets offering sports-event contracts are gambling and must comply with state regulations.

Circuit Split and Future Implications

This ruling creates a conflict with a previous 3rd Circuit decision concerning New Jersey, which found that sports wagers on prediction markets are indeed swaps. This split among federal appeals courts increases the likelihood that the US Supreme Court will consider the issue to provide a definitive legal interpretation.

How outlets covered it

New Jersey has petitioned the Supreme Court to determine if prediction market sports bets, like those offered by Kalshi, are gambling subject to state laws or financial "swaps" under federal jurisdiction. This action follows conflicting rulings from the 3rd and 9th Circuit Courts of Appeals, creating a circuit split that could impact the regulation of the multi-billion-dollar sports betting industry nationwide.

The 9th US Circuit Court of Appeals ruled against Kalshi's attempt to prevent Nevada from regulating its prediction market platform, upholding the state's authority. This decision is part of ongoing legal challenges faced by Kalshi and other prediction markets regarding state-level oversight versus federal regulation by the CFTC.

The 9th U.S. Circuit Court of Appeals ruled that gambling on sporting events is not protected by federal law, directly challenging a prior federal judge's order that blocked Arizona from prosecuting online prediction market company Kalshi. This decision could allow Arizona to proceed with its case against Kalshi for violating state gambling laws.

A federal appeals court ruled that Kalshi's sports-related event contracts are gambling and subject to state laws, not federally regulated swaps. This decision allows Nevada to enforce its gaming laws against Kalshi, conflicting with a prior 3rd Circuit ruling and increasing the likelihood of Supreme Court review.
