Polymarket Minnesota: Banned by Statute, Blocked by a Judge

Polymarket Minnesota is not a "the fight hasn't arrived yet" page like most states on this site — Minnesota is the one state that actually passed a law making it a felony to operate a prediction market, and then watched a federal judge stop that law from taking effect. Is Polymarket legal, legit, and safe in Minnesota right now? The honest answer: legally reachable today because of a court order, not because the state changed its mind.

Legal status in Minnesota

Minnesota has no licensed online sports betting market of any kind — multiple bills have failed since 2019 over a standoff between the state's 11 tribal nations, who want exclusive mobile licenses, and the Canterbury Park and Running Aces racetracks, who want a cut. A bipartisan Senate bill, S.F. 4139, was introduced in March 2026 to try again through tribal partnership; as of this writing it has not passed. Into that vacuum, Governor Tim Walz signed an omnibus public safety bill on May 18, 2026 containing language (drawn from S.F. 4760) making Minnesota the first state to outlaw prediction markets outright: creating, operating, or advertising a prediction market that lets users bet on future events became a felony punishable by up to five years in prison and a $10,000 fine, set to take effect August 1, 2026. The bill passed with lopsided margins — 100-32 in the House, 57-9 in the Senate. The CFTC sued Minnesota in federal court less than 24 hours after Walz signed it, and Polymarket and Kalshi filed their own suits soon after, all arguing the Commodity Exchange Act preempts a state from criminalizing a federally designated exchange's products. Attorney General Keith Ellison opposed every request for relief, calling the platforms "gambling, plain and simple" and arguing Minnesota was defending its "duly passed law." On July 27, 2026 — five days before the ban would have taken effect — U.S. District Judge Katherine Menendez granted a preliminary injunction blocking Minnesota from enforcing the law against Kalshi, Polymarket US, and the CFTC while the case proceeds. Her order found federal law likely preempts the ban for a "considerable swath" of the platforms' event contracts, but she stopped short of protecting every listed contract, meaning a later, narrower ruling is still possible. Ellison said the state "respectfully disagrees" and will keep litigating. As of this writing, no felony charge has been filed against Polymarket or any user, the injunction remains in place, and Minnesota still has zero licensed sportsbooks to offer as an alternative.

State gambling authority: Minnesota has no gaming commission overseeing online sports betting or prediction markets — the operative authority is Attorney General Keith Ellison, who is defending the felony ban (S.F. 4760, effective Aug. 1, 2026) in federal court after Judge Katherine Menendez preliminarily enjoined its enforcement against Kalshi and Polymarket on July 27, 2026

You may have read that Minnesota banned Polymarket. That is not false — it is just not finished. Minnesota is the only state on this site that wrote a felony prediction-market ban into law, watched the federal government and the platforms themselves sue over it, and then had a judge stop the ban five days before it would have taken effect.

Myth: Minnesota Banned Polymarket. Reality: A Judge Paused That.

Governor Tim Walz signed an omnibus public safety bill on May 18, 2026 that made it a felony — up to five years in prison, a $10,000 fine — to create, operate, or advertise a prediction market in Minnesota. It passed with lopsided votes, 100-32 in the House and 57-9 in the Senate, and was scheduled to take effect August 1, 2026. The CFTC sued the state less than 24 hours after Walz's signature. Polymarket and Kalshi filed their own suits soon after. On July 27, 2026, U.S. District Judge Katherine Menendez granted a preliminary injunction blocking Minnesota from enforcing the ban against Kalshi, Polymarket US, and the CFTC — five days before it would have become criminal law.

The injunction has a limit. Judge Menendez found federal law likely preempts Minnesota's ban for "a considerable swath" of the platforms' event contracts — not necessarily every single one. Attorney General Keith Ellison says the state "respectfully disagrees" and intends to keep litigating. This is a pause, not a final ruling.

Is Polymarket Legal in Minnesota? What the Injunction Actually Means

Right now, yes, in the specific sense that no Minnesotan using Polymarket US is at risk of the felony charge the legislature wrote — a federal court order says the state cannot enforce it while the case continues. That is different from the law being repealed. S.F. 4760's felony language is still on Minnesota's books. If Ellison wins on appeal, or if a later ruling narrows what "considerable swath" covers, the answer to this question could change without any new statute passing.

Why Minnesota Reached for a Felony Ban Instead of Regulation

Most states in this fight already license sportsbooks and are arguing prediction markets should be taxed and regulated the same way. Minnesota can't make that argument — it has no legal online sports betting market at all. The state's 11 tribal nations have insisted on exclusive mobile licenses since at least 2019; racetracks Canterbury Park and Running Aces want a cut or compensation for being cut out. Every bill has died on that disagreement, including a bipartisan Senate attempt, S.F. 4139, introduced in March 2026 that still hadn't passed as of this writing. With no licensed industry to fold prediction markets into, Minnesota legislators wrote a criminal ban instead — the bluntest tool available to a state with nothing else on the books.

Is Polymarket Legit and Safe in Minnesota?

Legit: Ellison's "gambling, plain and simple" framing is a regulatory argument, not a fraud allegation, and Polymarket US remains a CFTC-designated, KYC'd exchange regardless of how Minnesota's case resolves. Safe: usable today under the injunction, with the caveat that the protection is provisional and doesn't necessarily cover every contract type the platform lists. Neither answer is the same as a Minnesota regulator having reviewed and approved the product — no such regulator exists.

What This Means If You're in Minnesota

Watch the docket, not the statute book — Minnesota v. Kalshi remains active in federal court, Ellison has signaled an appeal, and the injunction could narrow before it ever gets to a final ruling. None of this makes Polymarket a way to make money, and an event contract here can expire worthless no matter which side wins the preemption fight. 21+ only, and if it stops feeling like a choice, 1-800-GAMBLER is free and confidential.

Polymarket Minnesota — Frequently Asked Questions

Is Polymarket legal in Minnesota?

Reachable, yes — but only because a federal judge is currently blocking the state from enforcing the law that would make it a felony. Judge Katherine Menendez granted a preliminary injunction on July 27, 2026, five days before Minnesota's prediction-market ban was set to take effect. The underlying law is still on the books and Attorney General Keith Ellison is still fighting to enforce it. "Legal" here means "enjoined," not "settled."

Did Minnesota really ban Polymarket?

Yes — Minnesota is the first state to pass an outright criminal ban on prediction markets, tucked into a public safety omnibus bill Governor Tim Walz signed May 18, 2026. Operating, running, or advertising one became a felony carrying up to five years in prison and a $10,000 fine. It just never actually took effect: the CFTC, Polymarket, and Kalshi all sued, and a judge blocked enforcement days before the August 1 effective date arrived.

Is Polymarket legit if Minnesota calls it a felony operation?

Ellison's office calls it "gambling, plain and simple" — a legal-classification argument about how the product should be regulated, not a claim that Polymarket rigs outcomes or withholds payouts. Polymarket US remains a CFTC-designated exchange with KYC accounts regardless of how Minnesota's case turns out. A state calling something illegal and a platform being fraudulent are two separate questions, and only the first one is actually in dispute here.

Is Polymarket safe to use from Minnesota right now?

Mechanically, yes — the July 27, 2026 injunction means no Minnesotan using Polymarket US is currently at risk of the felony charge the state legislature wrote. But Judge Menendez's order didn't protect every single contract type, only found the ban likely preempted for "a considerable swath" of them, and Ellison has said he'll keep litigating. That is a narrower, more provisional kind of safe than a state with no ban attempt at all.

What is Minnesota's S.F. 4760 prediction market ban?

The provision, folded into a broader 2026 public safety bill, made it a felony to create, operate, or advertise a prediction market allowing bets on future events in Minnesota — up to five years in prison, a $10,000 fine. It passed the House 100-32 and the Senate 57-9 and was signed May 18, 2026, before a federal judge blocked its enforcement against Kalshi and Polymarket on July 27, 2026, just before its August 1 effective date.

Why doesn't Minnesota have legal sports betting at all?

A different fight, running since 2019: Minnesota's 11 tribal nations want exclusive control of mobile sports betting licenses, while the state's two racetracks, Canterbury Park and Running Aces, want a share of the market or compensation for being excluded. Every bill has died on that disagreement, including the March 2026 bipartisan S.F. 4139 attempt. That stalemate is part of why lawmakers reached for a felony ban on prediction markets instead — Minnesota has no licensed sportsbook industry to lean on for comparison.
