A federal appeals court ruled on 28 August that states can regulate prediction markets as gambling, delivering the most significant legal setback yet to platforms that have spent two years arguing federal commodities oversight shields them from state gaming law. For anyone who follows the regulated betting industry — and that increasingly includes poker players who use the same operators for sports wagering — this is the ruling that changes the terrain.
Kalshi and Polymarket both hold Commodity Futures Trading Commission licences to offer event contracts, a form of derivative swap. That federal registration has been the foundation of their claim to operate in all fifty states regardless of local gambling statutes. The appeals court has now said that claim does not hold.
How the Conflict Built
The dispute has been escalating steadily through 2026. Forty-four states argued in July that prediction markets are gambling and should be subject to state gaming law and the tax regimes that accompany it. Their complaint is straightforward: a contract on the outcome of a football game is a sports bet in everything but name, and it is being offered without a state licence, without state consumer protections, and without paying state gaming tax.
Sports contracts in particular drew the fire, because their resemblance to state-regulated sports betting is hard to argue away. A licensed sportsbook in New Jersey pays tax, funds responsible gambling programmes, verifies age and location, and operates under a state licence that can be revoked. A prediction market offering an economically identical product on the same game did none of those things.
Individual states moved to block access. Washington became the fourth state to block Kalshi, joining Michigan, Nevada and Massachusetts. Minnesota went further, signing the first outright state ban on prediction markets on 18 May, due to take effect 1 August — though a federal judge blocked that law from taking effect on federal jurisdiction grounds.
Then in the same month, a New York federal judge refused to stop state regulators from enforcing gambling laws against prediction markets, finding that the state rules were not preempted by federal authority. The appeals court ruling on 28 August builds directly on that reasoning.
The Federal Counterweight
What makes the picture messy is that the platforms have federal political backing. The Trump administration has supported Kalshi and Polymarket's position even as states moved to ban them, and the CFTC has continued to license event contracts. Regulators and banks have both increased scrutiny in recent months, but the federal licensing pathway itself remains open.
So the industry now faces a genuine split: a federal regulator that permits the product, an administration that supports it, and an appeals court saying states may nonetheless apply their own gambling law. That is not a stable equilibrium, and it points toward either a Supreme Court appeal or federal legislation defining where the line sits.
Why Poker Players Should Care
Three reasons, and none of them are abstract.
First, the operators overlap. Many of the sportsbooks poker players already use sit in the same regulatory conversation. If prediction markets are pulled fully under state gaming law, licensed operators gain a competitive position they have been demanding for two years — and the market share currently sitting on prediction platforms has to go somewhere. Our sportsbooks section covers the licensed options, including the BetOnline sportsbook, SportsBetting.ag and the TigerGaming sportsbook.
Second, the precedent matters for online poker. The core question — whether a federally regulated product can override state gambling prohibition — is the same question that has shadowed interstate online poker for two decades. A ruling that strengthens state authority over gambling definitions cuts both ways: it reinforces states' power to prohibit, but it also reinforces the primacy of state-by-state licensing that has slowly expanded legal poker across the country. Our US poker guide tracks where that stands.
Third, consumer protection is not symmetric. A player on a licensed poker site or sportsbook has recourse: a regulator to complain to, segregated player funds, dispute resolution, and enforceable responsible-gambling tools. Those protections are the practical reason we point readers toward safe poker sites. Whatever the eventual legal outcome, the difference in protections between a state-licensed operator and a CFTC-registered exchange is real today.
What Happens Next
The immediate practical effect is uncertainty about availability. Prediction markets currently operate under a federal licence in most of the country but face active blocks in a handful of states and now a circuit ruling that invites more. Users should expect access to vary by state and to change without much notice.
The medium-term possibilities are:
- Supreme Court review. With circuit-level and district-level rulings pointing in different directions, and the federal government supporting the platforms, this is a strong candidate for certiorari. That would take a year or more.
- Federal legislation. Congress could define event contracts explicitly, either carving sports outcomes out of CFTC jurisdiction or preempting state law directly. Both directions have advocates.
- Negotiated licensing. The path several observers consider most likely: prediction markets seek state gaming licences in the largest markets, pay the tax, and accept the compliance burden in exchange for legal certainty. That converts a jurisdictional fight into a business-model question.
Historical Comparison
The closest analogue is the long fight over daily fantasy sports a decade ago. DFS operators argued their product was a game of skill and therefore outside state gambling law. Several state attorneys general disagreed, litigation followed, and the resolution was neither total victory nor prohibition — it was a state-by-state licensing regime that legitimised the product while subjecting it to gaming oversight and tax.
The same arc looks plausible here, and the DFS precedent is instructive on timing: the fight took roughly three years from first attorney general opinion to a majority of states having a workable framework. Prediction markets are perhaps eighteen months into their equivalent process.
There is a second, older parallel closer to home. The Unlawful Internet Gambling Enforcement Act reshaped online poker in 2006 not by declaring poker illegal but by attacking the payment layer. The lesson poker players learned then — that the legal status of the game and the practical ability to play are different questions — applies directly to prediction markets now. Payment processors and banks are already increasing scrutiny, and that pressure often bites before any court rules.
The Takeaway
Nothing about this ruling changes what happens at a poker table tonight. What it changes is the assumption that a federal licence is a universal permission slip. States have just been told they retain authority over gambling within their borders, and forty-four of them have already said they intend to use it.
For players, the practical guidance is unchanged and unglamorous: prefer operators that are licensed where you live, understand what protections you actually have, and do not assume that a product's availability today guarantees its availability next month.
