The Commodity Futures and Trading Commission and the U.S. Department of Justice sued Minnesota, Governor Tim Walz, and a handful of other state officials on Tuesday over a newly signed omnibus bill that bans prediction markets in the state.
The lawsuit, filed less than 24 hours after Walz signed SF 4760 into law, argues that Minnesota is unlawfully attempting to regulate federally overseen derivatives markets that fall under the CFTC’s “exclusive jurisdiction.” The complaint describes Minnesota’s legislation as “the first outright ban on prediction markets in the U.S.”
Under the new law, Minnesota prohibits prediction markets, which allow customers to wager on the outcome of everything from sporting events to weather, and company valuations to goings on in the government. The law is set to take effect on Aug. 1.
The CFTC and DOJ claim that these are federally regulated products and “swaps” that trade on CFTC-approved exchanges, and therefore are outside the authority of states to criminalize or prohibit them. “This flagrant and unprecedented incursion into the Commission’s exclusive regulatory sphere must be preliminarily and permanently enjoined,” the complaint reads.
The lawsuit is the latest escalation in a jurisdictional clash between state gambling regulators and federally regulated prediction market platforms like Kalshi and Polymarket. Several states, including Illinois, Arizona, and Connecticut, have also been sued by the CFTC for attempting to shut down prediction market platforms by arguing they break the states’ gambling rules.
The complaint also says the statute wrongfully extends criminal liability to banks, payment processors, media organizations, and sports leagues that advertise, verify, or provide data tied to prediction markets. The CFTC specifically pointed to partnerships that prediction markets have struck with organizations like Major League Baseball, the NHL, Fox, Dow Jones, and the Wall Street Journal.
The CFTC has spent the better part of 2026 honing its approach to event contracts under new Chairman Mike Selig. In March, the agency published a formal advisory on prediction markets and launched a campaign seeking public opinion on potential rulemaking.
Minnesota has meanwhile taken a mixed approach toward regulating crypto and blockchain-adjacent services. Earlier this week, Walz signed legislation allowing banks and credit unions to offer crypto custody services. Prior to that, in February, Minnesota became the second U.S. state, behind Indiana, to outlaw crypto ATMs and kiosks, claiming that they were primarily used in scams and fraud.

Executive Summary (TL;DR)
The CFTC’s swift legal counterattack against Minnesota’s prediction market ban exposes a fundamental jurisdictional conflict that threatens to reshape the digital asset landscape, establishing federal authority over event-based derivatives while creating immediate opportunities for compliant platforms.
The Core Friction
This battle transcends mere regulatory disagreement, representing a power struggle between states seeking gambling tax revenue and federal authorities asserting dominance over financial innovation. Minnesota’s legislation, while framed as consumer protection, directly challenges CFTC Chairman Mike Selig’s carefully constructed framework for event contracts—a framework designed to position the U.S. as a competitive hub for prediction markets amid global regulatory competition. The underlying friction stems from states viewing these platforms as unlicensed gambling operations while the federal government recognizes them as legitimate derivatives instruments.
Market Impact & Chain Reaction
- Short-term: Prediction market platforms like Kalshi and Polymarket will experience immediate volatility as regulatory clarity remains uncertain, but the lawsuit provides a temporary reprieve allowing operations to continue. Minnesota’s ban’s broad criminal liability provisions for partners including Major League Baseball, NHL, and Fox create secondary market disruptions affecting advertising and media partnerships.
- Mid-term: This conflict accelerates the flight of prediction market innovation to federal oversight frameworks, potentially boosting platforms with CFTC approvals while punishing state-level restrictive environments. Competitors like Augur or Omen may gain market share in less restrictive jurisdictions, but the long-term trend favors federally compliant structures that can navigate both gambling and derivatives classifications.
RichSilo Verdict
Smart money should monitor the CFTC’s evolving rulemaking process on prediction markets as the agency seeks to establish clearer boundaries between gambling and derivatives, with particular attention to how states with conflicting regulations respond to federal preemption. The ultimate resolution will determine whether prediction markets become a regulated asset class or remain in regulatory limbo, creating asymmetric opportunities for platforms that proactively align with federal frameworks while maintaining product innovation.
