Minnesota Becomes First State to Criminalize Prediction Markets

Minnesota has drawn a hard line against the booming prediction market industry. On May 18, 2026, Governor Tim Walz signed into law the nation’s first comprehensive ban on platforms like Kalshi and Polymarket, making it a felony to operate, host, or advertise such services within the state starting in August.

The law is sweeping: it prohibits not only the platforms themselves but also tools used to circumvent the ban, including VPNs. Violations can result in up to five years in prison and significant fines. Users placing bets are not criminalized, but operators face serious consequences.

Exceptions and Political Compromises

The final bill includes notable carve-outs:

Weather contracts — added after strong pressure from Minnesota’s powerful agricultural lobby, which relies on such instruments for hedging crop risks.
Certain insurance-style event contracts.

Despite these exceptions, the law represents the most aggressive state-level crackdown on the industry to date.

Federal Response: Trump Administration Strikes Back

Minnesota Becomes First State to Criminalize Prediction Markets — Sparking Federal Showdown Within 24 hours of the bill being signed, the Commodity Futures Trading Commission (CFTC) — under the Trump administration — filed a federal lawsuit seeking to block the law before it takes effect. The CFTC argues that prediction markets fall under exclusive federal jurisdiction as regulated “event contracts,” and that states cannot criminalize federally overseen markets.

This is not an isolated move. The CFTC has already filed similar lawsuits against Arizona, Wisconsin, and New York, with bills under consideration in 14 additional states.

The Core Conflict: Gambling vs. Event Contracts

Kalshi Raises <img Billion at Billion Valuation as Prediction Markets Go Institutional At the heart of the dispute is how prediction markets are classified. Platforms like Kalshi and Polymarket operate under CFTC oversight as event contract exchanges. This allows them to offer betting on elections, news, weather, and — crucially — sports outcomes in states where traditional sports betting is restricted or banned.

In Minnesota, only tribal casinos offer legal sports betting. According to reports, roughly 85% of Kalshi’s trading volume comes from sports-related events. A Nevada court previously ruled that such contracts are “indistinguishable” from regulated sports gambling.

Family Ties and Political Dimensions

Donald Trump Jr. and Kalshi: Place Your Bets, Gentlemen! The situation carries extra political weight: Donald Trump Jr. is not just a supporter but a co-founder/investor in Kalshi, adding a personal layer to the Trump administration’s aggressive defense of the industry.

The conflict also highlights deeper tensions in American politics:

States’ rights vs. federal preemption.
The desire for minimal regulation and innovation vs. concerns over gambling disguised as “information markets.”
Unusual incentives created by prediction markets (including bets on Trump administration actions that have reportedly performed with surprising accuracy).

What Comes Next

Minnesota Becomes First State to Criminalize Prediction Markets — Sparking Federal Showdown Minnesota’s ban sets a precedent, but the federal pushback suggests the industry is unlikely to be dismantled state by state.

Legal experts predict a prolonged court battle that could ultimately reach the Supreme Court, determining whether the CFTC truly holds exclusive authority over this rapidly growing sector.

As prediction markets move from niche financial tools to mainstream entertainment and information platforms, the fight in Minnesota may be just the opening battle in a larger war over who gets to regulate the future of betting on reality itself.
