Trump Administration Sues Minnesota Over Nationwide Prediction Market Ban

Federal Showdown Over State Authority

The Trump administration has launched a federal lawsuit against Minnesota, marking the latest escalation in a nationwide battle over who controls prediction markets like Kalshi and Polymarket. The Commodity Futures Trading Commission (CFTC) filed suit Tuesday after Governor Tim Walz signed the nation's first comprehensive ban on prediction markets Monday , setting up a constitutional clash over federal versus state regulatory power.

The CFTC called Minnesota's law "the most aggressive move by a state to shut down CFTC-regulated markets," arguing it undermines federal authority over derivatives trading. CFTC Chairman Michael Selig declared that "this Minnesota law turns lawful operators and participants in prediction markets into felons overnight," as the ban takes effect August 1st with potential felony charges for violations.

What's Really at Stake

Minnesota's sweeping law prohibits betting on athletic events, esports, emergencies, assassinations, short-term weather events, popular culture events, and even "whether a person will make a particular statement" . The legislation emerged from bipartisan concerns that these platforms constitute unregulated gambling disguised as financial instruments.

On Kalshi, more than 85% of trading activity relates to sporting events, including high-risk "parlays" where users wager on multiple outcomes simultaneously . Major news outlets including CNBC, CNN, Fox Corporation and Dow Jones have partnerships with prediction markets and could face prosecution under Minnesota's law , highlighting the broad reach of the ban.

Minnesota Representative Emma Greenman, who proposed the ban, noted the CFTC's lawsuit is "unsurprising, given the pressure they're under from President Trump—whose son has financial ties to the two largest prediction-market companies" through investments and advisory roles.

A Growing National Conflict

The Trump administration has filed similar lawsuits against Arizona, Connecticut, Illinois, New York, and Wisconsin over comparable prediction market restrictions . Questions over federal versus state oversight have already triggered more than 20 lawsuits nationwide , with some courts finding prediction markets "indistinguishable" from state-regulated gambling.

The stakes extend beyond gambling regulation. CFTC officials argue the ban could harm Minnesota farmers who rely on weather and crop-related derivatives to hedge agricultural risks , though Minnesota's law explicitly bars prediction market bets on short-term weather events .

Legal experts expect the fundamental question of whether federally regulated sports event contracts should be allowed in all 50 states will eventually reach the U.S. Supreme Court . With billions in monthly trading volume at stake and more states considering similar bans, this Minnesota case could determine whether prediction markets remain a federal or state regulatory battleground for years to come.
