Trump administration fights Minnesota law outlawing Kalshi, Polymarket-style markets

The Trump administration, through the Commodity Futures Trading Commission, is suing Minnesota to block a new state law that would outlaw prediction markets like Kalshi and Polymarket. The law, signed by Gov. Tim Walz, makes it a felony to offer event contracts on a wide range of outcomes. President Trump has said the federal government should retain exclusive authority over the industry.

Lead

The Trump administration is fighting Minnesota's decision to outlaw prediction markets like Kalshi and Polymarket, with the Commodity Futures Trading Commission suing the state to block a new law that would make hosting such markets a felony. The law, signed Monday by Gov. Tim Walz, was set to go into effect Aug. 1, but the CFTC argues it would criminalize lawful operators overnight.

Coverage Comparison

Reporting on the dispute comes from two outlets: The Guardian and the Jerusalem Post (via Reuters). Both agree on the core facts: the CFTC has filed a federal lawsuit against Minnesota, the law criminalizes a broad range of event contracts, and the Trump administration is asserting federal authority over prediction markets. The Guardian places greater emphasis on President Trump's personal stake in the industry, noting his social media statement and his family's ties to prediction market companies. The Jerusalem Post focuses more narrowly on the legal and regulatory conflict, including the law's specific provisions and the CFTC's broader legal actions against other states.

Key Claims

The Commodity Futures Trading Commission filed a federal lawsuit against Minnesota to overturn the state's new law banning prediction markets, according to multiple sources. The lawsuit was reported by both The Guardian and Reuters.
The Minnesota law makes it illegal to host prediction markets or offer "event contracts" for a wide range of events, including athletic events, esports, emergencies, assassinations, short-term weather, popular culture events, and even whether a person will make a particular statement. Violators could face felony charges. This detail was reported by Reuters and is not disputed.
The law was signed into law by Gov. Tim Walz and was set to take effect Aug. 1, according to Reuters.
President Trump wrote in a social media post that it was "critically important" for the federal government, specifically the CFTC, to retain "exclusive authority" over prediction markets. This was reported by The Guardian.
The CFTC has also sued five other states—Arizona, Connecticut, Illinois, New York, and Wisconsin—over their attempts to limit prediction-market companies from offering sports contracts, per Reuters.
Prediction markets allow users to make speculative bets on event outcomes, and their growth has attracted state attention due to gambling concerns, as reported by The Guardian.

Perspectives

Federal Government Perspective

The Trump administration argues that prediction markets are a form of derivatives trading, which falls under federal oversight via the CFTC. In a statement, CFTC Chairman Michael Selig said the Minnesota law "turns lawful operators and participants in prediction markets into felons overnight." The administration is also challenging similar restrictions in other states, asserting that federal law should take precedence.

State of Minnesota Perspective

Minnesota has enacted what Reuters describes as the first outright ban on prediction markets, viewing them as unlicensed gambling on real-world outcomes. The law covers a broad array of events and carries felony penalties, signaling the state's determination to regulate an industry it sees as skirting gambling laws.

Industry Critics and Experts

Critics of Kalshi, Polymarket, and similar platforms argue that event contracts amount to gambling while avoiding state gambling regulations. Experts also warn that insider trading can be rampant, as some outcomes can be manipulated or known in advance. The Guardian cites a recent case where a U.S. Army soldier allegedly used classified information to profit from bets on the capture of former Venezuelan President Nicolás Maduro.

President Trump's Personal Stance

While Trump has said he "was never much in favor" of prediction markets, he has argued for federal control over the industry. The Guardian reports that Trump's media company released a prediction market product last year and that his son Donald Trump Jr. has ties to two top prediction market companies. These ties have not been independently verified beyond The Guardian's report, but they frame the administration's legal push in a broader context of potential financial interests.

Background and Context

The dispute highlights a growing tension between state and federal regulators over the legality of prediction markets, which have surged in popularity and now command billions in weekly trading volume. The CFTC has traditionally overseen derivatives markets, but states have become more assertive in applying their gambling laws to platforms like Kalshi and Polymarket. The outcome of the Minnesota lawsuit could set a precedent for how these markets are regulated nationwide.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
