Is Polymarket legal?
· 7 MIN READ
Polymarket now runs a CFTC-regulated exchange in the US alongside its international crypto venue. Several state regulators disagree that this settles the question, and outside the US the answer varies country by country.
This is the most-asked question about prediction markets, and it has no single answer. The status changed substantially during 2025 and 2026, it differs between the United States and everywhere else, and inside the United States it differs between federal and state law.
Nothing here is legal advice. It is a summary of where the public record stands, so you know which question to ask about your own situation.
The federal position in the US
Polymarket left the US market in 2022 after a settlement with the Commodity Futures Trading Commission. It returned through the regulated route: it acquired QCEX, a CFTC-licensed exchange and clearing house, and in November 2025 the CFTC approved an amended Order of Designation for the entity now trading as Polymarket US.
A designated contract market is the same legal category as a futures exchange. It brings market surveillance obligations, clearing rules and regular reporting to the regulator. Whatever else is true, this is not an unregulated venue at the federal level.
Two separate venues
The consequence most people miss is that "Polymarket" now means two different things.
Global Polymarket is the original crypto-settled venue — USDC on-chain, international users, and not available to US users. Polymarket US is the CFTC-regulated exchange, accessed through the regulated intermediaries the designation contemplates.
They share a brand, not a rulebook. They do not necessarily share liquidity, market lists or settlement mechanics either, so a market you read about may simply not exist on the venue you can reach. Which venue that is gets determined by where you are, and the platform decides it, not you.
The states do not all agree
Federal designation has not ended the argument. In January 2026 the Nevada Gaming Control Board sued Polymarket's operating company in state court, arguing that event contracts on sports and similar outcomes amount to unlicensed wagering under Nevada law. A temporary restraining order followed in February, and in June 2026 the court granted a preliminary injunction barring those contracts in the state while the case proceeds.
The reasoning matters more than the result. The judge found the regulator "reasonably likely to prevail on the merits" and rejected the argument that the Commodity Exchange Act places these contracts solely under CFTC jurisdiction — holding that federal law does not preclude state enforcement. Federal designation, on that reading, is not a shield against state gaming law.
That is one court in one state, and comparable arguments elsewhere have gone differently. But it is a concrete answer to the question people assume is settled: being CFTC-regulated at the federal level did not, in Nevada, make the state question go away.
Outside the United States
There is no global rule. Some jurisdictions regulate event contracts as financial instruments; some treat them as gambling requiring a local licence; some have not addressed them at all. Availability is enforced by the platform, which restricts access from jurisdictions where it does not operate.
Two practical points. First, if a venue is not available where you are, that unavailability is the answer to your question — we will not help you work around it, and doing so typically breaches the platform's terms as well as whatever local rule prompted the block. Second, tax treatment is a separate question from legality, and one that catches people out even where trading is plainly permitted.
If you need certainty rather than a summary, the only reliable source is a lawyer who knows your jurisdiction.
