 The 38-state coalition's opposing amicus brief (filed April 24, 2026) will be tested at oral argument on May 4, 2026. The SJC ruling following this argument will be the first state supreme court decision on whether the coalition's federalism argument (states retain sovereign authority over gambling regulation) prevails over CFTC's exclusive jurisdiction claim.

+38 state AGs filed formal amicus brief April 24, 2026 in Massachusetts SJC case arguing states retain gambling regulatory authority. Their core argument: Dodd-Frank was designed for post-2008 financial crisis derivatives, not to create a nationwide pathway for unregulated sports gambling. This is now formally in the record as mainstream state AG legal theory opposing CFTC preemption.

 The May 4, 2026 oral argument scheduling confirms CFTC's state supreme court amicus strategy is advancing to the merits phase. This is the first state supreme court oral argument in the prediction market preemption litigation wave, making it the highest-stakes near-term judicial event for federal preemption doctrine.

+CFTC filed amicus brief April 24, 2026 in Massachusetts SJC asserting exclusive federal jurisdiction over Kalshi and all CFTC-regulated prediction markets. Argues CEA and Dodd-Frank give CFTC 'exclusive jurisdiction' preempting state gambling laws. This confirms the multi-jurisdictional defense strategy extends to state supreme courts, not just federal district courts.

 Massachusetts SJC oral argument scheduled for May 4, 2026 converts the case from 'pending indefinitely' to 'ruling likely by August-November 2026' (3-6 months post-argument). This accelerates the timeline for state supreme court precedent and increases pressure for SCOTUS review if the SJC rules against CFTC preemption, as it would create the first binding state supreme court precedent in this litigation wave.

+
+Massachusetts SJC oral arguments scheduled May 4, 2026, with ruling expected August-November 2026. This will be the first state supreme court ruling on federal preemption in prediction markets. If SJC rules for Massachusetts, it creates precedent that CFTC's federal preemption theory fails in state court — potentially enabling 50 states to independently regulate prediction markets even if CFTC wins in federal district courts. This adds a state court dimension to the circuit split pathway to SCOTUS.
