The Third Circuit's April 6, 2026, divided 2-1 ruling affirmed a preliminary injunction for Kalshi, determining that sports event contracts on designated contract markets qualify as swaps under the Commodity Exchange Act, granting the CFTC exclusive jurisdiction and preempting state gambling laws like New Jersey's. This first appellate victory contrasts with Ninth Circuit oral arguments on April 16, where judges questioned federal preemption in Nevada's challenge, signaling a nascent circuit split that elevates SCOTUS certiorari prospects. No certiorari petitions are docketed; losers may pursue en banc review, followed by 90-day petition windows. SCOTUS typically grants review in under 1% of roughly 7,000 annual petitions, often requiring circuit finality before acting.
