Before signing up on a platform to trade event contracts, it’s common to ask: Are prediction markets legal in the United States? We can’t give a simple yes or no answer to the question, since it can differ from state to state.
The fact is that prediction market sites are allowed to operate in the US under regulations by the Commodity Futures Trading Commission (CFTC). They’re classified as peer-to-peer (P2P) exchanges for trading binary event contracts in Yes/No formats. If an event occurs, the contracts settle at $1 each. Otherwise, they resolve to $0, meaning a loss.


First of all, prediction market sites are platforms where you trade contracts tied to real-world outcomes. The common event trading categories we often see are sports, politics, economics, culture, crypto, and climate.
If you want to ask: what is event trading? It simply involves buying and selling Yes/No contracts – Yes means an outcome will occur, and No implies the opposite. Here’s an example from politics:
| Event | Will the Democratic Party win the US Senate? |
| Yes | $0.68 |
| No | $0.32 |
Now, prediction markets operate under CFTC financial-market regulations in the United States. That’s why they’re accessible in the country, but it can vary from state to state. Generally, the Commission has authority over event contracts offered according to the Commodity Exchange Act.
We just explained that prediction trading involves event contracts. The markets are P2P, so trader supply and demand activity is what determines the contract price. When a contract records more purchases than sales, its price will typically increase, and vice versa.
Let’s say a Yes contract costs $0.60 and No costs $0.40. If more traders begin buying Yes, its price may increase to $0.80, while the cost of No drops to $0.20. Conversely, if many traders sell instead, the Yes price can decrease to $0.30, with No increasing to $0.70.
The bottom line is that prediction market sites don’t assign the rates directly. That’s one of the main differences mentioned in our prediction markets vs sportsbooks comparisons.
Now that you know how event trading works in the US, you may wonder what prediction market sites to use. Well, we’ve rated the best prediction market brands around. You can see them on the banners on this page. Here are the factors to consider to be sure a site is legit:
The criterion here is simple: platforms without CFTC-regulated contracts aren’t authorized to operate in the US. Therefore, you shouldn’t sign up with them. We usually confirm whether a site is under the Commission’s oversight by checking the details in its footer section.
CFTC rules require prediction market sites to verify the identity of traders. The process is necessary to confirm you’re eligible to trade and, more importantly, prevent fraud and money laundering.
Many platforms we review require KYC during registration. So, without completing it, you can’t deposit or trade. The good news is that the procedure is often automated, taking only a few minutes. You’ll only wait more than a day if manual review is necessary.
The order book is where you see outstanding buy and sell requests for a contract. That includes the prices and quantities available for trading. If you know how to read market prices, you can also tell the spread and liquidity from the details. We consider a transparent order book an indicator of a legit prediction market site because it shows the contracts are truly P2P.
We’ve seen many traders asking questions about site availability, contract settlement, KYC, and payouts. The answers will be specific to the platform you’re trading on. So, ideally, a legit prediction market site should have dependable customer service to assist you when you need it.
It’s best when the agents are active 24/7 via live chat and email. A comprehensive help center with articles explaining how the prediction market platform operates is also a good sign.
From what we’ve explained, these are the pros and cons of accessing prediction markets:
Prediction market brands available in the US offer event contracts in sports, economics, politics, crypto, culture, climate, and other categories.
