Ongoing litigation in multiple federal circuits centers on whether sports event contracts traded on CFTC-regulated platforms qualify as swaps under the Commodity Exchange Act or fall under state gambling authority. The Third Circuit has addressed related preemption questions, while the Ninth Circuit heard consolidated arguments in April 2026 involving platforms such as Kalshi. A circuit split or strong amicus participation from over 30 states could accelerate a certiorari petition, though no such petition has yet reached the Court. Traders view early acceptance as improbable given standard timelines for appellate rulings and the absence of an immediate circuit conflict.
