The U.S. Commodity Futures Trading Commission and Department of Justice filed a lawsuit against Illinois and various state officials on Thursday over the state's efforts to shutter prediction market providers.
Illinois sent cease-and-desist letters to some prediction market providers, arguing that the companies were offering sports gambling products that should be regulated under state law. The CFTC has argued that prediction markets are offering swaps products, which are regulated under the federal Commodity Exchange Act and therefore are under the "exclusive jurisdiction" of that regulator.
In the lawsuit, the CFTC continued this argument, saying Illinois's efforts "intrudes on" the CFTC's role, and that federal law preempts state regulations in this matter.
