Minnesota's Prediction Market Ban (SF 4760): What It Actually Says

Minnesota’s SF 4760 does something no other state has done: it makes prediction markets themselves illegal, not just their sports contracts. Signed May 18, 2026 and scheduled to take effect August 1, 2026, the law makes operating, hosting, or advertising a prediction market platform a felony carrying up to five years in prison and a $10,000 fine. The CFTC sued to block it within 24 hours.

What Does the Law Actually Cover?

SF 4760 bans prediction market platforms generally — not a specific contract type. That’s the detail that separates it from every other state action in this fight, most of which target sports event contracts specifically while leaving political and economic contracts alone.

The bill was passed as part of a larger omnibus public safety bill and prohibits creating, operating, hosting, or advertising a prediction market platform within Minnesota. It explicitly lists prohibited categories including sports, elections, war, popular culture, and weather-related event contracts — a broader scope than any of the roughly 20 other states currently disputing prediction markets, nearly all of which confine their fight to sports contracts. The law also extends liability to supporting infrastructure: geolocation providers, payment processors, and entities supplying event-data verification to platforms operating in the state.

The felony penalty is up to five years in prison and a $10,000 fine — a criminal exposure well beyond the civil cease-and-desist letters most states have used against Kalshi and Polymarket so far. Minnesota’s Commerce Department is also empowered to issue its own cease-and-desist orders ahead of any criminal referral.

Why Does the Advertising Provision Matter So Much?

The advertising ban is arguably the most consequential part of the statute, because it reaches beyond the platforms themselves to anyone promoting them to a Minnesota audience. That’s a meaningfully different target than every prior state action in this fight.

Most state disputes over prediction markets — the cease-and-desist letters, the lawsuits, even the criminal case Arizona filed against Kalshi in March 2026 — target the exchange operating the contracts. Minnesota’s law goes further, criminalizing the advertisement of a prediction market within the state. Legal analysts have described this as effectively de-platforming prediction markets from local media and social feeds serving Minnesota users, since a media outlet or affiliate marketer running a Kalshi or Polymarket ad campaign that reaches Minnesota residents could theoretically fall within the statute’s reach.

This is also the provision most likely to draw a First Amendment challenge alongside the preemption argument the CFTC is already making, though no such challenge had been separately litigated as of this writing. For context on how sports contracts specifically became the industry’s core legal battleground even before Minnesota’s broader ban, see our explainer on why sports event contracts are the flashpoint.

What Is the CFTC’s Lawsuit Actually Arguing?

The CFTC and DOJ sued Minnesota one day after Governor Walz signed the ban, arguing the same preemption theory the agency has used against eight other states: that the Commodity Exchange Act gives the CFTC exclusive jurisdiction over swaps, and that a state law criminalizing CFTC-registered contracts is preempted.

Filed May 19, 2026, the suit was the CFTC’s sixth state lawsuit in seven weeks at the time (it has since sued additional states, bringing the total past nine). The agency has publicly characterized Minnesota’s law as the most aggressive state action against prediction markets to date, given its criminal penalties and its reach into non-sports contracts and advertising. Kalshi separately sued Minnesota on its own behalf on May 28, 2026. See the full regulatory timeline for how this fits alongside the CFTC’s other eight state lawsuits and the Third Circuit/SDNY circuit split running in parallel.

A federal judge, Katherine Menendez, heard arguments on July 2, 2026 — less than a month before the law’s scheduled effective date. One theory reportedly under consideration is whether the ban can be preempted only as applied to contracts that pass the CEA’s “swap” definition, rather than struck down wholesale, which would leave some of the law’s broader reach (weather, pop culture) more exposed than its sports and election contract provisions. No ruling had been issued as of this writing.

How Does Minnesota Compare to Other States’ Actions?

Minnesota stands alone as the only state with an enacted outright ban; every other contested state is working through litigation, cease-and-desist letters, or court orders that leave platforms operating in some form while the case proceeds.

Nevada comes closest in scope — its restrictions cover sports, election, and entertainment contracts, not just sports — but Nevada’s action is a court-issued temporary restraining order arising from litigation, not a legislated criminal ban. Every other state currently disputing prediction markets (Arizona, Connecticut, Illinois, Iowa, Kentucky, Maryland, Massachusetts, Michigan, New Jersey, New York, Ohio, Rhode Island, Tennessee, Utah, Washington, Wisconsin, among others) confines its dispute to sports-related contracts specifically, and none has passed a statute equivalent to SF 4760.

What Happens to Minnesota Traders?

If the ban takes effect August 1 without a court injunction, Minnesota residents should expect platforms to geo-block the state rather than void existing positions outright, based on how Polymarket handled its 2022 US exit — though the statute’s public text does not spell out a specific process for open positions, and no platform has published a Minnesota-specific contingency plan as of this writing.

The law’s felony provisions target operators, promoters, and advertisers, not individual users placing trades — a distinction several legal analyses of the bill have highlighted. That’s not the same as saying Minnesota residents face zero risk; the statute’s broad definitions of “operate” and “promote” have not been tested, and this is exactly the kind of ambiguity a felony statute creates when it’s this new. Anyone currently holding open positions from a Minnesota address should treat August 1 as a real deadline until a federal court says otherwise, and should not rely on this article as legal advice for their specific situation.

Key Takeaways

• Minnesota’s SF 4760, signed May 18, 2026, is the first enacted state ban on prediction markets generally — not just sports contracts — and takes effect August 1, 2026 absent a court injunction.
• Penalties are criminal: up to five years in prison and a $10,000 fine for operating, hosting, or advertising a prediction market platform in the state.
• The advertising provision is unusually broad, reaching media outlets and affiliate marketers promoting platforms to Minnesota residents, not just the exchanges themselves.
• The CFTC and DOJ sued to block the law within 24 hours of signing; a federal judge heard arguments July 2, 2026 with no ruling yet as of this writing.
• The law targets operators and promoters, not individual traders placing bets — but the practical fallout for existing Minnesota positions if the ban takes effect remains unaddressed in public reporting.
