Judge Blocks First State Law That Would Have Banned Prediction Markets (arstechnica.com)

(Tuesday July 28, 2026 @05:00PM (BeauHD) from the not-so-fast dept.)


An anonymous reader quotes a report from Ars Technica:

> Minnesota, the first US state to prohibit prediction markets, was [1]prevented from enforcing the law by a federal court ruling just days before the ban was scheduled to take effect. But while Minnesota was stopped from enforcing a total ban, the state may ultimately be allowed to prohibit some types of prediction-market wagers. The Trump administration and the two largest prediction markets -- Kalshi and Polymarket -- sued Minnesota after the state [2]enacted the law in May . The cases were consolidated, and [3]a ruling (PDF) issued yesterday imposed a preliminary injunction blocking the law that was scheduled to take effect on August 1.

>

> Minnesota lawmakers saw prediction markets as indistinguishable from gambling, but the US Commodity Futures Trading Commission (CFTC) argues it has exclusive authority to regulate the platforms under federal law. One of the primary legal questions is whether event contracts are "swaps," which are regulated by the CFTC. Swaps are defined broadly in US law to include contracts in which payment "is dependent on the occurrence, nonoccurrence, or the extent of the occurrence of an event or contingency associated with a potential financial, economic, or commercial consequence." US District Judge Katherine Menendez in the District of Minnesota, a Biden appointee, said Minnesota's total ban on prediction markets is likely to violate US law because many trades on Kalshi and Polymarket are swaps.

>

> Menendez wrote: "Specifically, it appears that whether the Minnesota statute is expressly preempted turns on whether the state law attempts to regulate trades in event contracts that qualify as "swaps" within the meaning of the CEA [Commodity Exchange Act]. And there are several examples of event contracts hosted by Kalshi and Polymarket US that fit that definition because they concern the occurrence of events with clear potential economic, financial, or commercial consequences that are neither remote or unattenuated. Kalshi and Polymarket US are designated contract markets, so the CFTC has exclusive jurisdiction to regulate transactions involving those 'swaps.'"

>

> Menendez said the CFTC, Kalshi, and Polymarket met their burden of showing they are likely to succeed on the merits, so she issued "a preliminary injunction barring enforcement of Minnesota's prediction market statute until a final decision on the merits is reached." But she said Minnesota may be able to prohibit some types of event contracts offered on Kalshi and Polymarket because not all of them appear to meet the definition of swaps. For example, Menendez doesn't think prediction-market bets on the outcome of Love Island USA meet the legal definition of swaps. Minnesota could continue litigating the case in district court or ask a federal appeals court to overturn the preliminary injunction.

I don't give a flying fuck. That just means they are gambling...with event contracts. The contracts are the 'casino chips'; win and turn them into cash, lose and they go bye-bye.

It is.

I fundamentally disagree with all forms of stock markets and believe they should be eliminated worldwide. All companies should either be non-profit or for-profits, and all for-profits should be co-ops/profit shares among all employees. All utility providers should be non-profits and owned 100% by customers of that utility.

In a lot of cases, maybe even most it could be that functionally but there are still real assets under it and real direct economic interests in the outcomes for parties to those contracts and instruments, that alone separates it from simple wagering which is what a prediction market is.

Most of stocks, options and other financial instruments shift risk, or speculatively take on risk for potential gain. "predicting" who will get an Oscar, with a payout if you're right or loss of your "investment" if you are n

Financial swaps and gambling are differentiated by their economic function, legal classification, and risk management utility. While both involve a contingent transfer of money based on future uncertain events, swaps are commercial tools used to manage existing financial risk, whereas gambling creates artificial risk for entertainment or speculative profit.

I don't follow prediction markets that closely, but it seems to me that win or lose, this ruling shows they're screwed either way.

If they lose, showing that these are unregulated forms of gambling, then the states can come after them.

If they win and the injunction is dismissed, it's because these prediction markets are operating like credit default swaps, which are heavily regulated. This would force every prediction market to operate through clearing houses, eliminate direct holding of users' funds, force them to to become registered dealers, and most importantly limit their market to those who have high discretionary assets, because at least regulated swaps require you to have $10M in discretionary assets to even buy swaps.

Again I may be missing something here, but I read this as the injunction being put on hold because they could essentially be swaps; if that holds, then it could be argued they must then act like swaps which are highly regulated and would kill their retail business. I'd be curious to know if I'm missing something about these though that would suggest a different analysis.
