Minnesota Criminalized Prediction Markets, but Its Ban Is Blocked

Minnesota’s prediction-market felony law took effect on August 1, 2026, but it is not currently being enforced against the federally regulated exchanges that challenged it. A federal judge issued a preliminary injunction before the effective date, and the Associated Press’s account of the ruling says the restriction will remain blocked while the litigation proceeds.

That is the essential update to Minnesota’s first-in-the-nation action: the state did enact criminal penalties, and the federal confrontation did materialize, but platforms such as Kalshi and Polymarket did not have to leave Minnesota on August 1. The unresolved question is whether federal commodities law prevents Minnesota from treating their event contracts as gambling.

What Minnesota’s law actually criminalizes

The statute targets the commercial infrastructure behind prediction markets, rather than simply declaring every prediction or individual wager a felony. It covers creating a market; operating or controlling a platform intended for consumer wagers; administering prices, terms or settlements; regularly acting as a counterparty; knowingly supplying outcome data; and knowingly providing location or payment services used for prohibited transactions.

Advertising or marketing financial or technological products that promote the prohibited transactions is also a felony. Under Minnesota’s official Chapter 97 text, a conviction can bring up to five years’ imprisonment, a fine of up to $10,000, or both. The provisions apply to crimes committed on or after August 1, 2026.

The wording matters because the law is broader than a rule aimed only at the exchange that lists a contract. A company that knowingly supplies essential data, payment processing or location services could also fall within its scope. At the same time, the knowledge requirement means it is inaccurate to describe the statute as an indiscriminate ban on VPNs, payment companies or data providers.

The enacted exceptions are also narrower and more technical than a general carve-out for weather markets. Activities that are not legally classified as bets remain outside the principal prohibition, as do contracts regulated under specified Minnesota insurance chapters. Traditional securities, commodities and futures transactions are preserved through the state’s definition of what does not count as a bet; the law does not create a categorical exemption for every contract involving weather.

Why the ban did not shut down Kalshi and Polymarket

U.S. District Judge Katherine Menendez granted preliminary relief to the Commodity Futures Trading Commission, Kalshi and Polymarket on July 27. At this stage, the court has not issued a final judgment invalidating Minnesota’s statute. A preliminary injunction instead preserves operations while the court decides the merits, based partly on its assessment of the challengers’ likelihood of success and the harm enforcement could cause.

The immediate practical distinction is therefore between enactment and enforceability. Minnesota’s criminal provision exists and reached its statutory effective date, but the state cannot presently use it against the CFTC-registered exchanges protected by the injunction. Calling the law “repealed” or the dispute “settled” would go beyond the ruling.

The order also does not transform every prediction-market transaction into an unquestionably lawful product. The litigation concerns the reach of federal preemption and the status of event contracts offered through federally registered exchanges. Other operators, products or conduct may present different registration and statutory questions.

The federal-state conflict behind the injunction

The CFTC sued Minnesota on May 19, one day after Governor Tim Walz signed the legislation. In the agency’s announcement of its lawsuit, it argued that Minnesota was intruding on the federal framework for CFTC-regulated markets and asked the court to stop the law before August 1.

Kalshi and Polymarket frame their products as event contracts traded on designated contract markets. Their federal argument rests on the Commodity Exchange Act, which gives the CFTC exclusive jurisdiction over specified derivatives transactions, including swaps. If the challenged contracts fall within that federally governed category, the companies contend that Minnesota cannot prohibit them through state gambling law.

Minnesota takes the opposite view. The state characterizes wagers on sports, elections, entertainment and other discrete outcomes as gambling within its traditional police powers, even when the operator uses the language and structure of a financial exchange. Its position is that federal registration does not automatically convert every event wager into a transaction that displaces state authority.

This classification dispute explains why the injunction is more consequential than a routine delay. A final ruling favoring the challengers could restrict how Minnesota and other states apply gambling laws to registered prediction exchanges. A ruling for Minnesota could leave federally supervised platforms facing different gambling restrictions from state to state.

What remains unresolved

The preliminary ruling answers the short-term operational question but not the underlying jurisdictional one. Kalshi and Polymarket can continue serving Minnesota customers under the protection of the injunction, while Minnesota retains a duly enacted statute that it intends to defend. The court must still decide whether the relevant contracts are federally regulated transactions, state-regulated gambling, or a mixture requiring a more contract-specific analysis.

The result may not be an all-or-nothing rule for the entire industry. Event contracts can concern sports, elections, economic indicators, weather or other occurrences, and their legal characteristics may differ. A court could conclude that federal law preempts Minnesota’s restrictions for some CFTC-regulated contracts without immunizing every market or every supporting business activity.

For Minnesota users, the present status is straightforward: the August 1 date did not produce the anticipated shutdown of the principal federally registered platforms. For operators and service providers, however, the statute’s breadth still matters because the injunction is temporary, tied to ongoing litigation and not equivalent to a permanent nationwide resolution.

Minnesota has therefore created a felony framework without yet being able to apply it to the companies at the center of the controversy. The state-federal showdown is real, but as of August 14, 2026, it remains a pending court fight rather than a completed ban.
