States That Have Banned Prediction Markets May 2026
Prediction markets — platforms like Kalshi, Polymarket, and others where people bet on real-world events such as elections, economic indicators, sports outcomes, or weather — have exploded in popularity. However, they sit in a legal gray area: federally regulated by the CFTC as event contracts, but often viewed by states as a form of gambling.As of May 2026, only one state has passed a comprehensive statewide ban.
Minnesota: The First State to Ban Prediction Markets
In May 2026, Minnesota became the first state in the U.S. to explicitly ban prediction markets. Governor Tim Walz signed Senate File 4760, which makes it a felony for companies like Kalshi and Polymarket to operate or advertise in the state. The law takes effect on August 1, 2026.Minnesota lawmakers argued that these platforms function as unlicensed gambling operations, especially when they offer contracts on sports or elections. The ban has already triggered a federal lawsuit from the CFTC, which claims exclusive jurisdiction over these markets.
Other States Taking Strong Action
While Minnesota is the only state with a full statutory ban so far, many others are actively fighting prediction markets through enforcement actions, lawsuits, or proposed legislation:
- Nevada: Issued a temporary ban on Kalshi sports contracts, arguing they violate state gambling laws. One of the most aggressive gaming states.
- Arizona: Filed criminal charges against Kalshi, calling it an illegal gambling business.
- Maryland, Illinois, Michigan, Massachusetts, Ohio, Connecticut, Tennessee, New Jersey: Have issued cease-and-desist letters or are involved in ongoing litigation.
- Hawaii and North Carolina: Have pending bills that seek full statewide bans.
- Utah: Passed legislation expanding its gambling definition to cover certain prop bets on prediction platforms.
According to the National Conference of State Legislatures, bills targeting prediction markets were introduced in at least 14–15 states in 2026.
The Federal vs. State Conflict
The core issue is jurisdictional:
- The CFTC treats many prediction market contracts as legal “swaps” or event contracts under federal law.
- Many states argue that sports and election contracts are effectively gambling and fall under state authority.
This tension has led to multiple lawsuits, with the federal government (under the current administration) generally siding with prediction market platforms against restrictive state laws.
Current Landscape Summary (May 2026)
| Status | States / Details |
|---|---|
| Full Ban | Minnesota |
| Active Enforcement / Lawsuits | Nevada, Arizona, Maryland, Illinois, Michigan, etc. |
| Pending Ban Bills | Hawaii, North Carolina |
| Generally Allowed | Most other states (with legal uncertainty) |
Note: Even in states without explicit bans, users and platforms face significant legal risk depending on the type of contract (especially sports or elections).
Why Are States Cracking Down?
- Consumer protection concerns
- Tax revenue loss for state-regulated sports betting
- Gambling addiction fears
- Insider trading and manipulation risks (especially around elections)
Outlook for More Prediction Market Regulation
The battle is far from over. Legal experts expect the issue to eventually reach the U.S. Supreme Court to decide whether the CFTC has exclusive jurisdiction or if states can regulate (or ban) these platforms.Prediction markets are still accessible in most states, but the regulatory environment is rapidly evolving and highly uncertain.This article reflects information available as of May 23, 2026. Laws and court rulings can change quickly — always verify current regulations before using any prediction market platform.
