The US government has made its strongest case to date for regulating sports betting as a financial activity, rather than as a form of gambling. In a recent court filing, the Commodity Futures Trading Commission (CFTC) and the Department of Justice have requested that a federal court intervene to prevent Arizona from enforcing its state gaming laws against Kalshi, a prediction market operator.

The agencies contend that contracts related to sports, elections, and other real-world events are, in fact, financial derivatives known as swaps, which fall under federal jurisdiction. If the courts concur, this could result in a significant shift in the regulation of the rapidly growing prediction market, with control being transferred from individual states to the federal government, allowing operators to function nationwide under a unified set of rules.

At the heart of the matter lies a fundamental question: what defines a bet? Arizona, along with a growing number of states, views contracts on sports outcomes as akin to traditional wagers, subject to gambling regulations, including licensing requirements, age restrictions, and consumer protections. Arizona has taken a more aggressive stance, filing criminal charges against Kalshi under state betting laws, with a scheduled arraignment on April 13.

However, federal regulators have a differing perspective. They argue that the structure of these contracts, rather than the events they are based on, is the determining factor. Since the payouts are contingent on the occurrence of future events, which can have economic implications, these products are subject to the same legal framework as derivatives tied to commodities or interest rates.

This interpretation would place prediction markets squarely under the Commodity Exchange Act, granting the CFTC exclusive jurisdiction. It would also limit the ability of individual states to shut down or restrict these platforms, a scenario that regulators warn would lead to a fragmented, state-by-state system. The ongoing legal battle has been escalating for months, resulting in conflicting rulings. A federal appeals court in New Jersey recently ruled in favor of Kalshi, determining that its sports contracts are presumptively allowed under federal law unless the CFTC intervenes.

In contrast, courts in other jurisdictions have been more receptive to state arguments, permitting enforcement actions to proceed. The government has warned that allowing states to prosecute federally regulated exchanges would undermine a national market that Congress intended to be overseen at the federal level. If the courts ultimately accept the CFTC's position, prediction markets could operate nationwide under a single federal framework, effectively bypassing the current state-by-state system governing sports betting. Conversely, if the courts reject this position, these products could be forced into existing gambling regimes or shut down altogether in key jurisdictions.

For the time being, the federal government is adopting an expansive view of its authority, arguing that a contract on the Super Bowl is not fundamentally different from one tied to oil prices or interest rates. The decision now rests with the courts to determine the validity of this comparison.
