- ▸ Minnesota’s SF4511 would effectively ban advertising and offering prediction market trading in-state, passing the Senate with a veto-proof 56–10 margin.
- ▸ The bill faces a tight two-week window, a split House, and potential amendments, making final passage in 2026 far from guaranteed.
- ▸ If enacted, lawsuits are inevitable (likely invoking federal preemption), and the bill could serve as a “test case” ahead of a likely Supreme Court decision on state vs. federal control.
The Minnesota Senate has passed a bill that aims to impose restrictions on prediction marketing trading for people within the state’s borders. The legislation proceeds to the state House of Representatives, where members will need to process the measure quickly if it is to become law in 2026 with the legislative session ending May 18.
The bill is sure to meet immediate challenges in federal and state courts if it becomes law. However, the proposal could also represent a framework for future legislation if national court cases over prediction market regulation result in decisions friendly to other state governments.
Minnesota Senate File 4511 proceeds with veto-proof margin
On Friday, the Minnesota Senate voted 56-10 to approve SF4511. The bill makes it illegal for people inside the state to advertise or offer trading of a prediction market.
SF4511 defines a prediction market as an online “system that allows consumers to place a wager on the future outcome of a specified event that is not determined or affected by the performance of the parties to the contract.” The outcomes explicitly mentioned in the proposal include most categories of contracts available on exchanges.

The margin by which SF4511 passed in the Senate suggests that it might be sufficient to override a potential veto. Support in the House may not be as robust, especially in the short term remaining to consider the measure.
House has two weeks to process SF4511
The scheduled session end for the Minnesota legislature in 2026 is May 18. While there are mechanisms for extending the session, doing so only to consider SF4511 is unlikely.
The legislation has four Democratic sponsors and lacks any Republican endorsement. While the Minnesota Senate has a Democratic majority, the House is evenly split.
That could mean a tougher road forward for SF4511 in the House, and even if it does receive House approval, that’s no guarantee that will occur without amendments. Any amendments the House makes would necessitate Senate concurrence, which could represent delays the bill’s supporters can’t afford at this juncture.
SF4511 has not yet been assigned to any House committee as of the time of this writing. Should it become law in its current form, the proposal would take effect on Aug. 1, 2026.
Lawsuits in federal and/or state courts would be awaiting that date for filing in that event.
Legal challenges are inevitable if SF4511 becomes law
SF4511’s enactment would undoubtedly trigger at least one if not multiple legal challenges, potentially in multiple venues. Complaints against Minnesota on the subject could resemble established paths for these actions.
Prediction market platforms themselves would likely ask federal courts for injunctive relief barring Minnesota from enforcing the new law. It’s also possible that the Commodity Futures Trading Commission (CFTC) might file a similar complaint.
Arguments in these complaints will focus on federal laws governing commodity trading, arguing that Minnesota’s law is unconstitutional because it violates the Supremacy Clause. The timing of Minnesota’s enactment and existing court cases could change this narrative.
Could SF4511 be a “practice run” for future state regulation?
Multiple lawsuits in federal and state courts across the United States are currently adjudicating the nature of prediction markets and the sovereignty of state governments. For example, the CFTC has sued New York to stymie the enforcement of state laws against prediction market operators.
The likely end game of all these actions will be a decision from the US Supreme Court, establishing whether prediction markets fit the legal description of gambling and whether federal statutes preempt state laws on the matter. A ruling that favors the state governments will have many ramifications.
In that event, the language that SF4511 proposes would take on a new level of legitimacy for prediction markets in Minnesota. The bill’s proponents could bring the legislation to bear even if it fails in 2026.
Until the Supreme Court weighs in, state governments are attempting various strategies to exercise some control over prediction market trading. At this time, SF4511 represents the efforts of lawmakers in Minnesota.
