A broad bipartisan group of state attorneys general has intensified efforts to bring disputes over prediction market regulation before the Supreme Court. The moves come amid conflicting lower court rulings on whether platforms offering event contracts tied to sports outcomes fall under federal Commodity Futures Trading Commission oversight or state gambling laws.

New Jersey filed a petition last month asking the justices to review a Third Circuit decision favoring federal preemption in a case involving Kalshi. Other filings seek review of a Ninth Circuit ruling upholding Nevada's ability to enforce its sports betting restrictions. Legal observers note that a circuit split and multiple pending petitions increase the likelihood of Supreme Court involvement, potentially as early as the current term.

More than 40 states, led by officials from both parties including Nevada Attorney General Aaron Ford and Ohio Attorney General Dave Yost, have submitted amicus briefs and comment letters. These documents argue that Congress did not intend the CFTC to override traditional state police powers over gambling when it addressed financial derivatives after the 2008 crisis. The coalition spans states with legal sports betting and those that restrict it, underscoring shared concerns about consumer protections and state sovereignty.

The legal landscape remains uneven. Courts have blocked major platforms in Nevada, Michigan, and Washington, while prediction markets operate with varying restrictions elsewhere. Platforms maintain CFTC registration for many contracts, but states contend sports-related offerings function as unregulated wagers bypassing age verification and problem gambling measures.

The Trump administration has supported federal primacy through CFTC actions and amicus filings, aligning with industry arguments that uniform national rules benefit innovation. States counter that federal rules would erode decades of state regulatory expertise and revenue streams from licensed gaming.

Three petitions now sit before the Court. If accepted, arguments could occur in early 2027 with a decision possible by June, according to gaming law experts. The outcome would clarify boundaries between federal financial regulation and state control over activities resembling sports betting.
