Gaming Body Pushes Kalshi Sports Markets Fight to Supreme Court
A row that has rumbled through American courts for more than a year has now reached the US Supreme Court’s doorstep, with the industry’s biggest trade body weighing in on who gets to police sports-linked prediction markets. It is a dispute worth watching from this side of the Atlantic too, given how quickly prediction-style products have been testing the boundaries between financial trading and betting.
What’s been released
The American Gaming Association has filed a brief urging the U.S. Supreme Court to review a ruling that prevents New Jersey from enforcing its gaming laws against Kalshi sports event contracts.
The brief describes the Third Circuit’s decision in Kalshi’s favour as disruptive and argues there is no credible evidence Congress intended Dodd-Frank to have that effect.
The filing backs a petition lodged by New Jersey’s attorney general in September, and
Attorney General Jennifer Davenport argued the platforms should not be able to avoid state requirements simply because their products are structured as event contracts, noting that dozens of states across the ideological spectrum have opposed the practice.
The NFL has also filed in support of New Jersey, raising concerns about game integrity and arguing that prediction-market operators have not matched the safeguards used by licensed sports betting operators.
The Supreme Court has yet to decide whether it will even hear the case, and
as things stand, it has not agreed to do so.
Should the justices accept the petition, a ruling would likely not arrive until sometime in 2027.
What’s changed
New Jersey’s petition asks the justices to decide whether the Dodd-Frank Wall Street Reform and Consumer Protection Act removed states’ authority to regulate sports bets offered through CFTC-registered markets, challenging a Third Circuit ruling that bars the state from applying its gaming laws to Kalshi’s contracts.
Kalshi’s position, consistently, is that these are federally regulated financial instruments rather than wagers.
Lower courts have not been consistent on this point.
The Third Circuit’s finding conflicts with a Ninth Circuit decision in Kalshi’s Nevada case, where judges found the contracts amount to sports bets rather than swaps and are not shielded by the Commodity Exchange Act.
In a separate Illinois case, a district judge ruled on 2 October that the contracts at issue were likely swaps, granting preliminary injunctions in part while leaving other matters for further proceedings.
That patchwork of outcomes is precisely why New Jersey wants the Supreme Court to settle the question once and for all.
Where it fits
None of this changes licensing or product rules for UK players, since Kalshi does not operate in the regulated UK market and the Gambling Commission’s framework already treats sports-linked wagering as gambling regardless of how a product is structured financially. But the case is a useful marker for anyone tracking how other jurisdictions are drawing the line between trading platforms and betting products, a question that has started to surface in conversations around novel game formats and hybrid markets elsewhere too.
The dispute has significant implications for the rapidly expanding prediction-market industry, with platforms allowing customers to trade contracts tied to outcomes ranging from elections to sporting contests, while state officials contend that sports-related contracts function as wagers and should comply with state gaming rules.
Expect more amicus filings and parallel state cases before this one is anywhere near resolved.
