Is Kalshi legal in Minnesota? The ban that never started
Minnesota went further than any other state. Not a cease-and-desist, not a lawsuit, not a geofence deadline — a criminal statute banning prediction market platforms outright, signed into law and given an effective date. Then, days before that date arrived, a federal judge stopped it. The ban exists on paper and has never applied to anyone.
What changed since August
No new Minnesota action as of October 17, 2026: the injunction stands, no appeal to the Eighth Circuit has been publicly reported, and no trial or merits date has been set. The order itself is now public and worth reading precisely. It was issued on July 27, 2026 by U.S. District Judge Katherine Menendez in three consolidated cases, brought by the United States and the CFTC (No. 26-cv-2661), KalshiEX (No. 26-cv-2778) and QCX LLC, which trades as Polymarket US (No. 26-cv-2841); it enjoins enforcement of Minn. Stat. § 609.7615 "against entities that are registered as designated contract markets by the CFTC," on the finding that the plaintiffs "are likely to succeed, at least in part, on their express-preemption claims," while leaving the implied-preemption and First Amendment claims undecided (order, D. Minn.). The federal picture moved against the platforms elsewhere: the Ninth Circuit ruled for Nevada on August 28, the Sixth Circuit ruled for Ohio and Tennessee on September 25 that the Commodity Exchange Act does not preempt state gambling law, and on October 9 the CFTC published an interim final rule excluding licensed casino and sportsbook bets from the swap definition alongside a proposed rule to include event contracts, which Kalshi is citing in its rehearing petitions (CFTC release 9309-26). Neither circuit binds Minnesota, which sits in the Eighth Circuit alongside Iowa and Missouri, and no Eighth Circuit panel has ruled on the question. Attorney General Keith Ellison signed the brief of 39 states and the District of Columbia filed at the Supreme Court on October 7 supporting New Jersey's petition in Flaherty v. KalshiEX, No. 26-299; Kalshi's response is due November 9 (amicus brief). Kalshi and Polymarket remain available in Minnesota.
The timeline
| Date | What happened |
|---|---|
| May 18, 2026 | Governor Tim Walz signs SF 4760 as part of a broader public safety bill. Minnesota becomes the first US state to fully ban prediction markets. |
| May 28, 2026 | Kalshi sues Minnesota in federal court, arguing the law violates the Supremacy Clause given the CFTC's exclusive jurisdiction over event contracts. |
| Late July 2026 | A federal judge grants a preliminary injunction, blocking the ban days before it was due to start. |
| Aug 1, 2026 | Effective date passes. The ban does not take effect. |
| Aug 11, 2026 | Kalshi operating in Minnesota. Case proceeding on the merits. |
What the statute actually does
SF 4760 makes it a felony to create, operate, host or advertise a prediction market platform in Minnesota, punishable by up to five years in prison and a $10,000 fine. The verbs matter. Most state actions target the operator's licence status; this one reaches hosting and advertising, which pulls in affiliates, media partners and payment intermediaries alongside the exchanges themselves.
It also arrived attached to a public safety bill rather than a gaming bill, which is why it moved quickly and drew bipartisan support. That legislative route left it vulnerable in a specific way: a broad criminal prohibition is easier to enjoin than a narrow licensing requirement, because the constitutional conflict with federal law is starker.
Why the injunction landed
Kalshi's argument was the same one it makes everywhere: event contracts on a designated contract market are federally regulated derivatives, and under the Supremacy Clause a state cannot criminalise what the Commodity Exchange Act permits. In Minnesota that argument was at its strongest, because there was no ambiguity about whether the state was regulating gambling at the margins. It banned the product.
A preliminary injunction is not a win. It means the court thinks Kalshi is likely to succeed and that the harm of letting a felony statute take effect in the meantime outweighs the harm of pausing it. The statute stays on the books and can still be revived.
Where Minnesota fits nationally
| State | State's move | Result |
|---|---|---|
| Minnesota | Full statutory ban, felony | Blocked before taking effect, July 2026 |
| Arizona | 20-count criminal indictment | Permanently enjoined, May 2026 |
| New Jersey | Regulator shutdown order | State enjoined; 3rd Cir. affirmed 2-1 |
| Wisconsin | Civil suits under gambling law | CFTC's counter-injunction denied, July 2026 |
| Washington | State court injunction | Geofence due August 26, 2026 |
| Nevada / Michigan | Cease-and-desist plus deadline | Geofenced |
The pattern is sharper than it looks. Where a state acts through a criminal or blanket prohibition, Kalshi wins in federal court. Where a state acts through its gaming regulator and stays in state court, Kalshi tends to lose. The forum has mattered more than the argument. Full detail per state is in our 50-state tracker.
What it means for Minnesota users
Access is normal today, but Minnesota carries a distinct kind of risk. In Nevada or Washington the downside is a geofence — you lose access. Here the statute reaches conduct, and if the injunction were lifted the prohibition would be criminal rather than administrative. That is a meaningful difference for anyone hosting or advertising, less so for individual users, but it is worth knowing which category of risk you are in.
The near-term milestones are the merits ruling in district court and any appeal to the Eighth Circuit. Neither has a public date.

FAQ
- Is Kalshi legal in Minnesota?
- Yes, for now. The state's ban was blocked by a federal preliminary injunction in late July 2026 and never took effect on August 1.
- What does the ban say?
- SF 4760 makes creating, operating, hosting or advertising a prediction market platform a felony punishable by up to five years and a $10,000 fine.
- Why was it blocked?
- Kalshi argued the Supremacy Clause bars a state from criminalising federally regulated event contracts. The court found that likely to succeed and paused the law.
- Is the ban dead?
- No. A preliminary injunction pauses enforcement during litigation. The statute remains law and could take effect if the state prevails.
