Minnesota Senate Advances Bill to Ban Prediction Markets

ST. PAUL, Minn. (GRAY) – A bill to outlaw prediction markets in Minnesota has cleared its first legislative hurdle, advancing out of the Minnesota Senate State and Local Government Committee on a voice vote on April 9, 2026. This move comes as lawmakers express increasing concerns over the unregulated nature of platforms like Kalshi and Polymarket, which allow users to bet on the outcomes of various events.

Proponents of the bill argue that these platforms currently operate outside the bounds of state gambling laws, creating a legal gray area that could lead to unethical practices. “I think if you ask people two years ago about prediction markets—a year ago—[they’d have said] ‘what are you talking about?’ This year, it’s gone from down here to [up] here,” said Senator John Marty (DFL-Roseville) during the committee hearing. His comments highlight a growing awareness of prediction markets among the public and lawmakers alike.

The bill's supporters are particularly worried that prediction markets can skirt state gambling regulations and may become breeding grounds for insider trading. Senator Erin Maye Quade (DFL-Apple Valley) emphasized this concern, stating, “I have a really good friend who works for an elected official who’s planning to announce a run for something else, and I know exactly what day that they’re going to announce or that they’re planning to announce before most other people know. I can bet on that. The person who runs the campaign can bet on that. The member themselves can bet on that.”

These insights into the potential misuse of prediction markets have prompted lawmakers to take action. The bill's companion measure in the House was set aside in the House Commerce Committee earlier this week, but the Senate version is now slated to move on to the Senate Commerce Committee for additional consideration.

Meanwhile, as legislative discussions in Minnesota progress, the broader implications of prediction markets are becoming increasingly apparent. These platforms have gained traction as a niche financial market, drawing both participation and capital but operating without clear regulatory frameworks. One notable example occurred recently when a bet on whether the United States and Iran would reach a cease-fire by April 7 was posted on Polymarket on March 24, 2026. Around $107 million was wagered on this bet, illustrating the substantial financial stakes involved.

On the day of the cease-fire announcement, at least 50 accounts placed substantial 'Yes' bets before the official announcement was made by former President Trump at around 6:30 p.m. One user reportedly wagered $72,000 at 10 a.m. when the probability of a cease-fire stood at just 8.8%, later earning $200,000 from that bet. Another user placed a bet just 12 minutes before the announcement, netting $48,500. These instances raise ethical questions about the timing and motivations behind such bets.

Prediction markets function by allowing participants to trade 'yes or no' contracts on specific events, with the price of each contract representing the probability of the event occurring. Transactions are recorded on a blockchain-based distributed ledger, which ensures transparency and prevents manipulation. As the market continues to evolve, it has attracted attention from major Wall Street firms, with platforms like Polymarket and Kalshi securing substantial investments. Polymarket recently reached a valuation of about $9 billion after securing large-scale investment from the Intercontinental Exchange, the parent company of the New York Stock Exchange.

Critics of prediction markets argue that they commodify serious issues, including war and human suffering. Some have described these platforms as “unethical gambling” that trivializes the consequences of real-world events. For example, Polymarket faced backlash for listing a bet on when a missing U.S. military pilot would be rescued, which it later removed. In response to these ethical concerns, bipartisan legislation has been introduced in Congress to ban bets related to deaths or war and to prohibit participation by public officials.

Internationally, the regulatory environment for prediction markets varies widely. Countries such as France, Taiwan, and Singapore have blocked access to Polymarket, classifying it as an illegal gambling site. In the U.S., the Commodity Futures Trading Commission (CFTC) had previously treated prediction markets as gambling until a federal court ruled in favor of Kalshi in 2024, prompting the CFTC to reconsider its regulatory approach.

As prediction markets gain traction, they are also seen as valuable tools for aggregating information. Market experts have noted that data feeds from these platforms are increasingly being used to influence trading algorithms in traditional financial markets. For example, outcomes from prediction platforms like Polymarket are reportedly affecting trading in global Brent crude futures, illustrating their growing impact on investor sentiment.

Concerns about the potential for manipulation of public opinion through prediction markets have also emerged. As these platforms continue to evolve, the debate surrounding their ethical implications and regulatory needs will likely intensify.

The discussion in Minnesota reflects a broader national conversation about the role of prediction markets in society. As lawmakers grapple with the implications of these platforms, they must balance the benefits of innovative financial tools against the potential risks they pose to ethical standards and regulatory compliance. The outcome of Minnesota's legislative efforts could set a precedent for how prediction markets are treated across the country.

As the Senate Commerce Committee prepares to take up the bill, its implications for future regulation of prediction markets will be closely watched by both proponents and opponents. With the stakes high and the conversation growing, the outcome could significantly shape the future of this burgeoning sector.
