Polymarket challenges Michigan gambling authority in court
"Polymarket runs a designated contract market under the supervision of the Commodity Futures Trading Commission, or CFTC. On its platform, users trade event contracts, which are financial products tied to the outcomes of real-world events. In its complaint, the company says Congress granted the CFTC "exclusive jurisdiction" over these kinds of derivatives, arguing that states have no authority to regulate or prohibit them."
"The legal fight erupted just one day after Michigan Attorney General Dana Nessel sued Kalshi, another CFTC-regulated exchange, in state court. In that lawsuit, Nessel claims that offering sports-related event contracts to Michigan residents amounts to unlicensed sports betting under state law. The complaint mirrors concerns raised by the Michigan Gaming Control Board, which recently confirmed it is investigating sports prediction markets."
""The threat to Polymarket US is immediate and concrete," the company wrote in its complaint seen by ReadWrite, pointing to Michigan's March 3 lawsuit against Kalshi. It says it faces a "real and imminent risk of enforcement," including potential civil fines, criminal liability, and an order."
Polymarket filed a lawsuit in U.S. District Court for the Western District of Michigan seeking to block state enforcement of gambling laws against its event-based trading platform. The company operates as a designated contract market under CFTC supervision, where users trade financial products tied to real-world event outcomes. Polymarket argues that Congress granted the CFTC exclusive jurisdiction over these derivatives, meaning states lack authority to regulate or prohibit them. This legal action follows Michigan Attorney General Dana Nessel's lawsuit against Kalshi, another CFTC-regulated exchange, claiming sports-related event contracts constitute unlicensed sports betting under state law. Polymarket contends it faces immediate enforcement risk including civil fines and criminal liability.
