Pennsylvania attorney general Sunday joins coalition asking Supreme Court to weigh prediction markets
Pennsylvania Attorney General Dave Sunday is joining a multi-state coalition asking the U.S. Supreme Court to clarify whether prediction markets fall under state gambling laws. Sunday's office did not name which states are co-signing the brief or which operators are targeted. The Supreme Court has not yet signaled whether it will take the case. The action aligns Pennsylvania with other state attorneys general pushing back against event-contract platforms they argue encroach on state-regulated gambling.
Sunday's entry widens the state front already pressing the Supreme Court to strip CFTC-registered platforms of federal preemption. Kalshi faces parallel state pressure in multiple jurisdictions. Pennsylvania adds electoral weight to the roughly 40-state cert push, making denial costlier for the court.
If the Supreme Court grants review, it decides whether CFTC registration blocks state gambling law nationwide. A denial leaves operators funding defenses in every filing state, with traders holding contracts whose validity shifts at state lines.
