CFTC sued Minnesota after the state approved a law banning prediction markets run by platforms including Kalshi and Polymarket.
The agency says the measure conflicts with federal derivatives law and would punish firms and users operating under oversight.
The case places state authority and federal market regulation into a major legal fight.
Federal Regulator Pushes Back Against State Ban
The lawsuit followed Governor Tim Walz’s approval of the Minnesota law, which takes effect on August 1.
The measure would block companies from operating, hosting, or promoting prediction markets. Minnesota is the first US state to pass a full ban targeting these markets.
Prediction markets allow users to buy contracts tied to future events, including elections, sports results, economic data, and entertainment outcomes.
Supporters say these contracts are financial products overseen by the CFTC. Critics argue they resemble online gambling and could expose vulnerable consumers to risks.
The CFTC argues that Minnesota cannot regulate supervised derivatives markets through state criminal penalties.
The regulator says Congress gave it authority over event contracts and exchange activity. It also claims the state law could make lawful market participation a criminal act.
Minnesota Defends Consumer Protection Law
Minnesota officials say the ban is meant to protect residents from products they view as gambling disguised as financial trading.
State leaders have raised concerns about younger users, low-income residents, and the use of event contracts linked to sports outcomes.
Attorney General Keith Ellison said his office would defend the law and challenge the social impact of prediction markets.
He argued that such platforms can encourage harmful betting behavior and benefit wealthy participants at the expense of ordinary users.
State regulators in several regions have made similar arguments against prediction market operators.
Some officials say firms such as Kalshi offer unlicensed gambling products and may reach users below state gambling age limits.
However, operators say their markets are legal financial instruments because they function under federal exchange rules.
Court Fight Could Shape National Rules
The Minnesota case adds to a wider legal battle over prediction markets across the United States.
The CFTC recently secured a court order blocking Arizona from pursuing a criminal case against Kalshi. Nevada remains the only state with a court-enforced ban on Kalshi still in effect.
Massachusetts is waiting for a decision on whether it can enforce an injunction against Kalshi’s sports-event contracts.
These disputes have created uncertainty for platforms, investors, regulators, and consumers.
If the CFTC wins, states may face limits when trying to ban federally regulated prediction markets. If Minnesota prevails, other states could follow with similar restrictions.
The outcome could define how far state governments can go when financial event contracts overlap with gambling concerns.
