Minnesota Prediction Markets: The First State Ban and the Injunction Keeping It Open

Right now, yes — Minnesota residents can trade CFTC-regulated event contracts, because the state’s ban is blocked and cannot be enforced. That is the accurate one-line answer as of August 2, 2026, and it needs the full sentence: Minnesota enacted SF4760, which would have made offering these markets a felony beginning August 1, 2026, but U.S. District Judge Katherine Menendez granted a preliminary injunction on July 27, 2026 that forbids the state from enforcing the ban against federally registered designated contract markets. The markets are available not because Minnesota licensed or welcomed them, but because a federal court told the state to stand down while the lawsuit plays out.

Read that as “available pending litigation,” not “settled and safe.” The injunction is preliminary, it rests on a federal-preemption theory that other courts have rejected, and the judge herself flagged that a permanent order could be narrower than the pause she granted. Attorney General Keith Ellison is still defending the statute. If you want the shortest honest phrasing: the ban is currently blocked, so the markets are open, but nothing here is final.

Most states that moved against prediction markets in 2026 reached for a cease-and-desist letter or a licensing-and-tax scheme. Iowa, Kentucky and North Carolina all leaned toward taxing or regulating the products rather than erasing them. Minnesota went the other direction entirely. Instead of trying to fold event contracts into a state framework, it made offering them a crime.

The prohibition started life as a standalone measure, SF3432, and was folded into SF4760, the omnibus public-safety bill that carried the session’s criminal-law changes. Walz signed the package on May 18, 2026. What made the moment notable was not just the policy but the margins: the Minnesota House passed SF4760 by a 100-32 vote and the Senate by 57-9. Those are not party-line numbers. Prediction markets drew opposition across the aisle, and the bill’s own authors described the result as making Minnesota the first state in the nation to ban the products outright.

The operative language did a few distinct things, and the distinctions matter for the litigation that followed:

• It made it a felony to create, operate, manage or control an online prediction-market platform that serves Minnesota residents.
• It separately made it a felony to host or advertise such a platform in the state. That advertising clause is not a footnote — it is the hook for a standalone First Amendment challenge that rides alongside the main preemption fight.
• It set an effective date of August 1, 2026, giving operators a narrow window to pull out of Minnesota or risk criminal exposure.

Supporters built their case on two themes. The first was consumer harm — the argument that always-on, uncapped event contracts function as a new and largely unregulated form of gambling aimed at ordinary residents. The second was the interests of Minnesota’s tribal nations, whose casino gaming operates under state compacts and who view unlicensed national platforms as a direct competitor that pays none of the compact obligations they do. Those two arguments explain the lopsided votes better than any national partisan storyline does, and they are why the tribal angle keeps surfacing in coverage of the case. You can pull the underlying records for SF4760 and its predecessor SF3432 from the Minnesota Legislature’s bill system at the state revisor’s site (revisor.mn.gov) if you want the enacted text and roll-call detail rather than a paraphrase.

The signature set off one of the fastest legal responses the sector has seen. Within days, three separate challenges converged on the new law, and the striking feature was who lined up where. This was not simply industry versus a state. The federal government sued Minnesota too.

• The U.S. Department of Justice and the Commodity Futures Trading Commission brought suit against the state, with the CFTC asserting that it holds exclusive jurisdiction over event contracts traded on registered exchanges and that Minnesota’s criminal ban trespassed on federal ground. Minnesota is one of nine states the CFTC has taken to court in 2026, a group that also includes Arizona, Connecticut, Illinois, New York, New Mexico, Rhode Island, Wisconsin and Kentucky.
• Kalshi filed its own challenge, casting the ban as preempted by federal commodities law. Kalshi has made a habit of suing states preemptively, and Minnesota fit the pattern.
• Polymarket followed with a parallel suit. Both operators attached First Amendment claims aimed squarely at the felony-to-advertise provision, arguing the state cannot criminalize truthful commercial speech about a lawful federally regulated product.

The alignment is worth sitting with, because it scrambles the easy narrative. A Republican administration’s Justice Department and the CFTC joined the very platforms Minnesota tried to outlaw, arguing the state overstepped federal authority. And the judge who ultimately paused the law was appointed by a Democratic president. Whatever one thinks of prediction markets, this is not a clean left-right fight, and any framing that treats it as one is missing the actual dispute, which is about which government — state or federal — gets to regulate these contracts.

Four days before SF4760 was to take effect, U.S. District Judge Katherine Menendez granted a preliminary injunction barring Minnesota from enforcing the ban against CFTC-registered designated contract markets. Menendez, a Biden appointee, found that the plaintiffs had, in her words, “met their burden to show they are likely to succeed on the merits” of the federal-preemption claim, that they would suffer irreparable harm without relief, and that the balance of equities and the public interest favored pausing the law. The order tells the state it may not prosecute federally registered exchanges under the ban while the case proceeds.

That injunction is the single reason Minnesotans can reach these platforms today. But it is not the unqualified victory some headlines suggested, and two features of the order keep it from being one:

Ellison has signaled the state will keep defending the law rather than fold, which means the availability Minnesotans enjoy today rests entirely on a preliminary order that a later, permanent ruling could reshape or shrink. Polymarket’s legal team publicly cast the decision as a win for federal authority over a state-by-state patchwork — the company’s chief legal officer, Neal Kumar, framed the Minnesota result in exactly those terms — but the “not preempted in all its applications” language is a reminder that even a sympathetic judge left the state a lane. If you want to follow the case directly rather than through coverage, the docket is trackable through CourtListener, and the CFTC posts its filings and statements at cftc.gov.

Zoom out and the Minnesota case is a data point in a much larger argument playing out in federal courts around the country. The whole vertical hangs on a single classification question: are the sports and event contracts these platforms list a federally regulated financial product, or are they gambling that each state gets to police? Treat them as swaps under the Commodity Exchange Act and the CFTC’s authority crowds out state gambling law. Treat them as bets and every state gaming regulator has a say, and the platforms are unlicensed operators. Courts have landed on both sides of that line, and Minnesota now sits, provisionally, with the platforms.

The appellate map explains why the Menendez order carries weight beyond Minnesota. In April 2026, the Third Circuit ruled for Kalshi in KalshiEX LLC v. Flaherty, holding that sports event contracts are swaps and that federal law preempts New Jersey’s gambling statutes as applied to those contracts on a registered exchange — the industry’s biggest win to date, though it was a 2-1 decision with a pointed dissent and only a preliminary-injunction ruling, not a final judgment. Pulling the other way, a Ninth Circuit panel heard a consolidated appeal out of Nevada in April and, by most accounts, sounded skeptical of the platforms; a ruling for Nevada there would create a direct split between the circuits and make Supreme Court review close to unavoidable. That decision was still pending as of August 2, 2026.

What makes Minnesota distinctive within that landscape is the bluntness of its approach. It did not send a cease-and-desist, did not stand up a licensing regime, did not try to tax the products. It reached straight for a criminal ban — and lost the first round on preemption. That makes the Menendez order one of the cleanest recent examples of a federal court stopping a state ban cold. It also makes Minnesota an early candidate to test the next phase of the fight, the contract-by-contract question the judge gestured at, in which even courts friendly to the platforms start asking whether a particular market really is a swap or just a wager wearing a swap’s clothes.

If you have only ever used a sportsbook, the mechanics here will feel different, and the difference is central to the legal argument. A prediction market is an exchange. When you buy a contract, you are not betting against a house that sets the line and profits from the vig — you are trading a yes-or-no contract with another participant on the other side. Each contract settles at either 100 cents or zero depending on whether the event happens, and the live price between those poles reads as the market’s implied probability. A contract trading at 63 cents is the crowd pricing roughly a 63 percent chance.

Because you can buy or sell before an event resolves, you can lock in a profit or cut a loss without waiting for the outcome, the way you would exit any position on an exchange. That order-book, peer-to-peer structure is exactly what the platforms point to when they argue these are derivatives rather than sports bets, and it is what skeptical judges wave away — one Ninth Circuit judge called the peer-versus-bookmaker distinction “sophistry to the nth degree.” For a Minnesota resident the practical upshot is simple: you are trading on a federally registered exchange, the pricing looks like a probability rather than American odds, and the platform earns from fees rather than from building an edge into the line.

The menu on these exchanges runs well past sports, and it is worth knowing the categories because the legal exposure is not uniform across them. Sports contracts — who wins the game, series and futures markets, some player and prop-style questions — drive the overwhelming majority of volume industry-wide and are the flashpoint in nearly every state case. Beyond sports you will find political and election markets, economic contracts tied to data releases like inflation prints and interest-rate decisions, crypto price markets, and a grab bag of entertainment and cultural questions.

That range matters in Minnesota specifically because of the judge’s caveat. The preemption shield is strongest for the products that look most like classic regulated derivatives, and it is weakest for the ones that look most like a straight wager. If the litigation moves toward a permanent ruling that sorts contracts by type, the categories most likely to draw state authority are precisely the ones that dominate the sports book of business. So a Minnesotan trading today should not assume that “the markets are open” means every category is equally secure over the coming months.

Beyond those three, the platforms we review that trade or distribute event contracts are listed below. Several are distributors rather than exchanges — Robinhood, Coinbase and Crypto.com route contracts listed by others — so a given market’s Minnesota availability can depend on the underlying exchange as much as the app. Pick’em operators (PrizePicks, Underdog, Sleeper) run a parlay-style peer format rather than a full order-book exchange. Confirm each platform’s own Minnesota status before signing up.

The full lineup sits on our prediction markets hub.

Two practical realities follow from the fact that these are federally regulated exchanges rather than Minnesota-licensed gambling operators, and neither is obvious from the marketing.

On taxes, the treatment is genuinely unsettled, and this is not tax advice. Kalshi does not issue 1099-B forms for event contracts, the IRS has published no formal classification guidance for this product, and whether gains should be reported as gambling income, ordinary capital gains, or under the Section 1256 rules that cover many regulated futures remains an open question. The reporting can also differ depending on whether a contract was listed by an exchange or distributed through a brokerage, so a Minnesotan using two different platforms may face two different paperwork situations. Keep your own records of every position, and if the amounts are meaningful, talk to a Minnesota tax professional rather than relying on a platform’s default handling.

The bigger gap is in consumer protection, and it is the flip side of the preemption argument the platforms are winning. Because these exchanges answer to the CFTC and not to Minnesota, they sit outside the state’s gambling-protection framework. There is no Minnesota self-exclusion registry that covers them, no state complaint or dispute-resolution channel for these products, and minimum ages are often 18 — lower than the 21 Minnesota requires for tribal casino gaming. If the state ultimately prevails and platforms are forced out, operators elsewhere have generally let users close positions and withdraw funds on the way out, but the current order writes no such guarantee. FanDuel Predicts, with its voluntary limits and self-exclusion tools, is the one meaningful exception to that gap, which is why it is worth a look for anyone who wants guardrails the sector otherwise does not provide.

Here is the wrinkle that makes prediction markets so relevant to Minnesotans in particular: the state never legalized online sports betting. Repeated legislative pushes have stalled, so unlike residents of neighboring states, Minnesotans have no licensed mobile sportsbook to use. That vacuum is a big part of why event contracts drew attention here at all — for a lot of users, a Kalshi sports market has been the closest available thing to a legal online bet on a game.

But close is not the same. A licensed sportsbook operates under state gaming rules, pays state taxes, enforces a 21-plus age floor and plugs into state responsible-gaming tools. A prediction market operates under federal registration, prices contracts as probabilities rather than odds, lets you trade in and out of a position, and — as the section above lays out — sits outside Minnesota’s consumer protections. They are not interchangeable products, and they are not on the same legal footing: one is a licensed activity the state chose to allow, the other is a federally regulated product the state tried and failed, for now, to ban.

Set Minnesota beside the other states fighting this out and its posture looks both harsher and, so far, less successful than most. Nevada has been the most aggressive, layering cease-and-desist letters, a state restraining order and even a contempt threat against Kalshi for allegedly failing to geofence — and Kalshi, unlike Robinhood and Crypto.com, refused to withdraw voluntarily. New York opened two fronts, losing a federal injunction bid by the platforms and then having its attorney general file a state-court petition seeking enormous financial penalties. Arizona went the furthest of anyone, converting a restraining order into a permanent injunction in May 2026 — the first district-level merits ruling that federal law preempts state gambling statutes as applied to these markets. On the other side, Tennessee has been the clearest win for the platforms, with a federal judge granting and then extending an injunction on the theory that sports event contracts are likely CFTC-regulated swaps.

Minnesota is the outlier in method. Where those states used regulators, prosecutors or licensing bills, Minnesota legislated a flat criminal ban — and it is the only state to have done so. That is exactly why the Menendez injunction reads as such a clean test of the preemption question, and why the case is worth watching even from outside Minnesota. The nearest thing to a comparison is not a neighboring state at all but the broader federal split: Minnesota now sits, provisionally, in the same column as the Third Circuit and Tennessee, against the direction the Ninth Circuit appeared to be leaning.
