Polymarket is a real prediction market founded in 2020, where you trade shares on the outcome of events. Its history is bumpy: the CFTC fined it in 2022 and it blocked US users for years, before buying a CFTC-licensed exchange to return. Several countries ban it, and you can lose everything you put into a position.
Polymarket gets quoted on the news whenever there's an election or a big world event, so plenty of people wonder whether it's a real platform or a crypto gamble dressed up as data. I've pulled together what's on the public record, from its run-ins with US regulators to the countries that block it, so you can judge it on facts.
Who's behind Polymarket
According to Wikipedia, Shayne Coplan founded Polymarket in 2020. The company is headquartered in Manhattan, New York City, and its legal domicile is in Panama. Its own documentation describes it as the world's largest prediction market and offers an API for traders and developers who want market data.
So it's not a fly-by-night app. It's a well-known company with a named founder, big trading volumes and plenty of press coverage. That doesn't settle whether it's right for you, but it does answer the scam question.
How trading on Polymarket works
Polymarket runs markets on questions such as who'll win an election or whether something happens by a date. You buy shares in an outcome, and the share price reflects how likely traders think that outcome is. If you're right when the market resolves, your shares pay out; if you're wrong, they're worth nothing.
Wikipedia says users deposit cryptocurrency through the Polygon blockchain network on the main platform. That brings crypto risks on top of trading risks: wallet security, network fees and the chance of sending funds to the wrong address.

Polymarket's history with US regulators
This is where the legit question gets interesting. In 2022, according to Wikipedia, the CFTC fined Polymarket 1.4 million US dollars and issued a cease-and-desist order, including for failing to register as a swap execution facility. After that, Polymarket blocked US customers for years.
In 2024 the FBI raided Coplan's home and seized his phone, and Bloomberg reported the Department of Justice was looking into whether US-based users could still bet on the site. In 2025, Wikipedia says, the CFTC and DOJ ended their investigations without bringing new charges.
| Year | What happened, per Wikipedia |
|---|---|
| 2020 | Polymarket founded by Shayne Coplan |
| 2022 | CFTC fine of 1.4 million US dollars and cease-and-desist order; US users blocked |
| 2024 | FBI raid on the founder's home during a DOJ inquiry |
| 2025 | CFTC and DOJ investigations closed with no new charges; US return approved |
How Polymarket came back to the US
Polymarket bought QCEX, a CFTC-licensed derivatives exchange and clearinghouse, for 112 million US dollars. Wikipedia says that let it operate legally in the US, and it received an Amended Order of Designation from the CFTC in 2025. Its documentation now points to a separate Polymarket US product.
That means the US version and the main international platform aren't necessarily the same thing, with the same rules. Check which one you're signing up to and read its own terms, because what's allowed, how you fund it and how you withdraw can differ.
Where Polymarket is banned or blocked
Location matters a lot here. Wikipedia lists France, Brazil, Italy and Gibraltar as having banned Polymarket, and says access is restricted or blocked in other places including Australia, Belgium, Spain, Switzerland, Singapore, South Korea and Denmark.

In the US, Nevada obtained a preliminary injunction and Minnesota enacted a ban, which shows states are pushing back here too. Using a VPN to get round a ban breaks the platform's rules and can put your funds at risk, so don't.
The catch with Polymarket
- You can lose all the money you put into a position.
- On the crypto-based platform, wallet mistakes and scams can cost you funds that can't be reversed.
- Rules differ between the US product and the international site.
- Bans and restrictions keep changing country by country and state by state.
- Event markets can be emotionally gripping, which makes overtrading easy.

Fake Polymarket sites and wallet scams
Copycat sites and fake airdrops follow every popular crypto brand. Type the address yourself, never connect your wallet to a site you reached from a random link, and never share a recovery phrase with anyone claiming to be support. Real support won't ask for it.
So, is Polymarket legit?
Yes, it's a real and very large prediction market with a licensed US arm, and US regulators closed their investigations without new charges. It also has a regulatory history, crypto risks and a list of countries where it's banned. Check that it's allowed where you live, read the terms for the version you use and only trade money you can afford to lose.
