Kalshi Minnesota: A Felony Ban That Missed Its Start Date

Kalshi Minnesota is legal today for one reason: a federal judge stepped in five days before a felony law aimed squarely at Kalshi was set to take effect. Minnesota became the first state to criminalize running a prediction market, not just regulate one, and then watched a court freeze that law before it ever had a single day in force. This page covers the felony statute, the injunction that stopped it, and what is actually true right now.

Legal status in Minnesota

Minnesota has no legal statewide sportsbook market at all — a long-running standoff between the state's 11 tribal nations, who want exclusive control of mobile licenses, and the two commercial horse tracks, Canterbury Park and Running Aces, who want a cut, has killed legalization bills every session since 2019. A bipartisan bill, S.F. 4139, was introduced in 2026 to route mobile betting through the tribes, but it remains a low priority and has no confirmed path to passage. Into that vacuum, Gov. Tim Walz signed S.F. 3432 on May 18, 2026, making Minnesota the first state to criminalize prediction markets outright rather than treat them as unlicensed gambling. The law makes it a felony — up to five years in prison and a $10,000 fine — to create, operate, manage, or advertise a prediction market platform in Minnesota, or to knowingly supply one with data, payment processing, or geofence-bypass services such as a VPN; it targets the companies and their vendors, not individual bettors. The law named Kalshi and Polymarket in coverage and legislative debate even though the text is platform-neutral. It was set to take effect August 1, 2026. Kalshi, Polymarket US, and the Trump administration's Department of Justice each filed separate federal suits against the state, naming Attorney General Keith Ellison, Gov. Walz, and Alcohol and Gambling Enforcement Division Director Jon Anglin as defendants, arguing the Commodity Exchange Act gives the CFTC exclusive jurisdiction over event contracts and preempts a state from criminalizing them. On July 27, 2026 — five days before the law would have gone live — U.S. District Judge Katherine Menendez granted a preliminary injunction in a 44-page order, finding the plaintiffs are likely to succeed on preemption for contracts that meet the federal definition of a swap, and that Kalshi and Polymarket would suffer irreparable harm if the felony statute took effect. She was careful to note the injunction is not absolute: not every contract listed on either platform necessarily qualifies as a swap, so any final, permanent ruling could end up narrower than the preliminary order. As of this writing, S.F. 3432 has never been enforced for a single day, Minnesota's Attorney General has not said whether the state will appeal to the Eighth Circuit, and Kalshi continues to operate in Minnesota under the injunction rather than under any state license, because none exists to hold.

State gambling authority: Minnesota Alcohol and Gambling Enforcement Division (AGED), Department of Public Safety — named in the Kalshi injunction; no licensing authority over sportsbooks exists because none are legal statewide

No other state on this site wrote a felony law aimed at prediction markets. Minnesota did, and then watched a federal judge freeze it five days before it would have taken effect. Kalshi has never spent a single day operating under an enforced Minnesota ban — only under the threat of one, and now under the injunction that stopped it.

A State With No Sportsbook of Its Own

Start with what Minnesota doesn’t have: a legal sports betting market. Every legalization bill since 2019 has died in the same standoff — the state’s 11 tribal nations want exclusive control of mobile licenses, the two commercial horse tracks, Canterbury Park and Running Aces, want a cut or compensation, and neither side has budged. A bipartisan tribal-led bill, S.F. 4139, was introduced in 2026, but it’s a low legislative priority with no confirmed path forward. DFS apps and horse-track wagering are the only legal betting-adjacent products Minnesotans have today.

Is Kalshi Legal in Minnesota? The Felony Law That Missed Its Start Date

Into that vacuum, Gov. Tim Walz signed S.F. 3432 on May 18, 2026 — the first state law anywhere to make running a prediction market a felony rather than a civil gambling violation. It carries up to five years in prison and a $10,000 fine for anyone who creates, operates, manages, or advertises a prediction market platform in Minnesota, and it reaches vendors too: anyone who knowingly supplies a platform with data, payment processing, or a geofence-bypass service like a VPN. Individual bettors aren’t the target — the companies and their infrastructure are. It was set to take effect August 1, 2026.

Minnesota’s ban, start to freeze:

May 18, 2026 — Gov. Walz signs S.F. 3432 into law
Felony penalty: up to 5 years in prison, $10,000 fine
Kalshi, Polymarket US, and DOJ each file separate federal suits
July 27, 2026 — Judge Katherine Menendez grants a preliminary injunction, 5 days before the law would start
August 1, 2026 — the law’s effective date passes with the statute frozen, never enforced

Three Plaintiffs, One 44-Page Order

Kalshi and Polymarket US sued separately, and so did the federal government itself — the Trump administration’s Department of Justice joined as a third plaintiff, naming Attorney General Keith Ellison, Gov. Walz, and Alcohol and Gambling Enforcement Division Director Jon Anglin as defendants. All three argued the same theory: the Commodity Exchange Act gives the CFTC exclusive jurisdiction over event contracts, and a state can’t criminalize what federal law already regulates. On July 27, 2026, Judge Katherine Menendez agreed in a 44-page order, finding the plaintiffs likely to succeed on preemption and that they’d suffer irreparable harm if the felony statute took effect five days later.

The order isn’t a blanket clearance. Judge Menendez was explicit that her reasoning applies to contracts that meet the federal legal definition of a swap — and noted not every contract Kalshi or Polymarket lists necessarily qualifies. A final, permanent ruling could end up narrower than this preliminary injunction. “Blocked for now” is accurate. “Cleared permanently” is not.

Is Kalshi Legit in Minnesota?

As a company, yes — CFTC designation since 2020, KYC-verified accounts, dollar settlement, the same starting point as every other state page in this series. A felony law getting frozen in court isn’t a legitimacy problem for Kalshi; it’s an unresolved fight over how far a state can reach into federally regulated contracts, and Minnesota picked the hardest version of that fight to pick.

Is Kalshi Safe to Use in Minnesota Right Now?

You can open an account and trade from Minnesota today under the July 2026 injunction — no felony statute currently applies. Safe here still means CFTC oversight and KYC verification, not investment-safe, and not a guarantee that survives whatever comes after Judge Menendez’s preliminary order.

Kalshi Minnesota — Frequently Asked Questions

Is Kalshi legal in Minnesota?

Right now, yes, functionally — but only because a federal judge blocked the law written to stop it. Gov. Tim Walz signed S.F. 3432 on May 18, 2026, making it a felony to operate a prediction market in Minnesota, effective August 1. On July 27, 2026, five days before that start date, Judge Katherine Menendez granted a preliminary injunction finding the law is likely preempted by federal commodities law. The felony statute has never actually taken effect.

Was Kalshi actually banned in Minnesota?

On paper, briefly, yes — Minnesota passed a real felony law naming the conduct. In practice, no: the injunction landed before the law's effective date, so it never had a single day of enforcement. That distinction matters, because headlines saying "Minnesota bans prediction markets" describe the statute Walz signed, not the state Kalshi actually operates in today.

Why did Minnesota make this a felony instead of a civil fine?

Most states suing Kalshi are enforcing existing gambling statutes or issuing cease-and-desist letters under civil authority. Minnesota wrote a new criminal law specifically for prediction market operators — up to five years in prison and a $10,000 fine — and extended it to vendors who knowingly provide data, payments, or VPN-style geofence workarounds. It is the most aggressive statutory language any state has used against Kalshi, which is part of why the federal government itself sued to stop it.

Is Kalshi legit in Minnesota?

As a company, yes — CFTC designation since 2020, KYC-verified accounts, dollar settlement, the same baseline as every state page in this series. A blocked felony law is not a fraud finding; it is an unresolved argument over whether a state can criminalize a federally designated exchange at all.

Is Kalshi safe to use in Minnesota right now?

You can open an account and trade from Minnesota today under the July 2026 injunction. Safe here still means CFTC oversight and KYC verification, not investment-safe, and not a permanent legal clearance — Judge Menendez's own order left room for a narrower final ruling, and the state has not said whether it will appeal.

Does Minnesota have a licensed sportsbook alternative to Kalshi?

No. Minnesota has no legal statewide mobile or retail sports betting market of any kind — a standoff between the state's 11 tribal nations and its two horse tracks has stalled every legalization bill since 2019, including a tribal-led proposal, S.F. 4139, introduced in 2026. DFS platforms and pari-mutuel horse wagering are the only legal betting-adjacent products in the state today.
