The US government has made a strong case 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 and the Department of Justice requested a federal court to prevent Arizona from enforcing its gaming laws against Kalshi, a prediction market operator.

The agencies argue that contracts related to sports, elections, and other real-world events are financial derivatives, known as swaps, which fall under federal oversight. If the courts agree with this interpretation, it could lead to a shift in control of the rapidly growing prediction market from individual states to the federal government, allowing these platforms to operate nationwide under a unified set of rules. However, the core issue in this case revolves around the definition of a bet. Arizona and several other states consider contracts on sports outcomes to be equivalent to traditional bets and believe they should be regulated as such, with requirements for licensing, age restrictions, and consumer protection.

Arizona has taken a more aggressive approach, filing criminal charges against Kalshi under state betting laws, with an arraignment scheduled for April 13. In contrast, federal regulators contend that the structure of these contracts, rather than their subject matter, is the determining factor. Because the payouts are contingent upon the occurrence of a future event with potential economic implications, these products are considered to be under the same legal framework as derivatives tied to commodities or interest rates. This interpretation would place prediction markets firmly under the Commodity Exchange Act, granting the CFTC exclusive jurisdiction and limiting the ability of individual states to restrict or shut down these platforms.

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, finding that its sports contracts are presumptively allowed under federal law unless the CFTC intervenes. However, courts in other jurisdictions have been more receptive to state arguments, allowing enforcement actions to proceed. The government has warned that permitting states to prosecute federally regulated exchanges would undermine a national market intended to be overseen at the federal level.

Ultimately, if the courts 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 might be forced into existing gaming regimes or shut down altogether in key jurisdictions.

For the time being, the federal government is taking a broad 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 courts must now decide whether this comparison is valid.
