The NFL has submitted a filing backing New Jersey authorities in their petition to the U.S. Supreme Court regarding Kalshi, a federally regulated event contracts exchange. According to the league, Kalshi and other prediction markets "threaten game integrity" because many event contracts are "highly susceptible to manipulation." This argument mirrors concerns the NFL has raised about unregulated or lightly regulated betting markets. The league's support signals that it views state-level oversight as a necessary tool to protect the outcomes of its games.
The case centers on whether New Jersey can enforce its gambling laws against Kalshi's sports-related event contracts. Kalshi operates under Commodity Futures Trading Commission (CFTC) oversight, which the company argues gives it federal authorization to offer these contracts. New Jersey authorities, however, contend that these products function like sports bets and should be subject to state regulation. The Supreme Court petition asks the justices to review whether federal law preempts state gambling statutes in this context.
The NFL is the most prominent sports league in the United States, and its endorsement of New Jersey's position could carry weight with the Supreme Court. The league has previously partnered with regulated sportsbooks, but it has consistently opposed betting products it believes pose a risk to game integrity. By siding with state authorities, the NFL is effectively arguing that state regulators are better positioned to police sports-related event contracts. This stance could encourage other leagues to file similar briefs or support state-level restrictions.
The outcome of the petition could determine how event contracts are regulated across the United States. If the Supreme Court takes the case and rules in favor of New Jersey, states could gain clearer authority to restrict or ban sports-related event contracts. Such a ruling would affect not only Kalshi but also other prediction market platforms that offer similar products. The dispute therefore extends beyond one company, touching on the boundary between federal financial regulation and state gambling laws.
Kalshi is a U.S. exchange regulated by the Commodity Futures Trading Commission that offers event contracts, which are financial instruments that pay out based on the outcome of specific events, including sports. It has been at the center of legal disputes over whether such contracts are subject to state gambling laws.
The NFL argues that Kalshi's event contracts threaten game integrity because they are highly susceptible to manipulation. The league believes that state authorities need the ability to regulate these markets to prevent potential interference with sporting outcomes.
The petition asks the Supreme Court to review whether New Jersey can enforce its gambling laws against Kalshi's sports-related event contracts. The key legal question is whether federal regulation of event contracts preempts state gambling statutes.
If the Supreme Court agrees to hear the case, its ruling could set a nationwide precedent on the regulation of prediction markets. A decision in favor of New Jersey would give states more power to restrict sports event contracts, while a ruling for Kalshi would reinforce federal authority over such products.

Prediction markets and sports betting both involve wagering on outcomes, but they are regulated differently. Kalshi's contracts are structured as event contracts under federal oversight, while traditional sports betting is regulated primarily at the state level. The legal dispute centers on whether this distinction holds in practice.
