Prediction Markets Explained: How Do Prediction Markets Work and What is a Prediction Market?

What is a prediction market, and how is it different from regular betting? If you’re here, there’s a good chance you want answers to this question, along with a guide to help you get started.

Prediction markets aren't the same as betting sites because you’re basically taking a position on real events and what you think will happen. On this page, we’ll share everything about prediction markets, what they are and how they work. Also, we'll highlight if they’re legal, and how accurate they can be when events roll around.

What is a prediction market?

A prediction market is a site, app, or any online platform that lets you take positions on real-world outcomes by trading event contracts (shares), instead of going against the house. These contracts are binary and come in the form of YES or NO shares. Going for YES means you think the event will occur. Going for NO means you think it won't happen.

You’ll find markets on almost everything to predict on. There are extensive markets for elections, finance, entertainment, crypto, sports, tech, and even weather. So you can predict if you think it will rain on a certain day or not. If it matters in real life, there's probably a market for it.

Each market poses a simple question, usually something like “What price will gold close at in 2025?” or "Will the AI bubble burst in 2026?” All you have to do is click YES or No.

We must mention that the value of shares change based on people's perceptions and occurrences.

And for many, it's a good way to track public expectations in real time. You may find our guide on Kalshi vs Robinhood interesting if you're curious about some of these markets.

How prediction markets work

Now we've answered the pressing question: What is a prediction market? Let's see how they work. Honestly, it isn't as complicated as it first seems.

Just as we've mentioned, prediction markets are all about simple yes-or-no contracts.

Each contract has a value somewhere between $0 and $1, and that price shows what people think the chances are. If a YES contract is trading at $0.40, it means the market is saying there’s a 40% chance that the event will happen. And if it settles as true, that YES becomes $1 and you get $0.60 as profit. But if it turns out false, it becomes $0 and you lose the $0.40 you used to trade.

Just like we covered in our guide on what is event trading, you’re not backing a team or dealing with preset odds. You’re buying a contract at the market price and trying to get in at a level that you're comfortable with. So if you bought YES at $0.40 and the event happens, you get $1. If you bought NO at $0.30 and the event doesn’t happen, that settles at $1 instead.

That said, prices are hardly static as they keep changing as users trade, new events occur, or due to changes in other users' perceptions. So you must be prepared for this, and you can sell your position at any time, even before the event happens, which is an upside to prediction markets.

How accurate are prediction markets?

Prediction markets can be pretty good at reflecting what people think will happen, but they’re far from being perfect. When a market has a lot of traders and everyone is reacting to new information, the prices usually settle around a fair estimate of the chances. It’s just like watching a room full of people adjust their guesses in real time based on new information received.

They don’t always get it right though. Some markets aren't very active, so a few users can cause noticeable changes to the price easily. Other times the topic is totally unpredictable, and no one has reliable information to work with.

So they’re useful, and often a bit better than polls when there’s enough interest and activity. But they’re still just probabilities made by people reacting to the moment.

Are prediction markets legal in the US?

Now that you have answers to what is a prediction market, it’s natural to wonder if they’re actually legal in the US. So, are prediction markets legal in the US? The simple answer is yes, they are. Long answer? - Only prediction markets and platforms that are approved by the Commodity Futures Trading Commission (CFTC) are legal. Our guide on Kalshi vs Polymarket spotlights some of the best platforms in this space.

These sites are generally available nationwide, although certain states like New York may still block access for their various reasons. Each operator keeps an updated list of where they can and can’t offer markets, so you’ll always know if you can go on to register. You also need to be at least 18 years old, and KYC verification is a must.

Ready to try prediction markets for yourself?

Prediction markets are a simple way to turn what you're knowledgeable about into something you can act on.

You’re not holding assets or dealing with charts. You’re instead taking a side on what you believe will happen in the future. It could be who wins a presidential election, what the price of Bitcoin will be at the end of the year, or even what the highest grossing movie will be in 2025.

There’s a wide range of topics to choose from, and you'll often find more than enough to interest you. Remember though, that events can swing either ways, and nothing is really 100% certain.

If you feel you’ve got a bit of insight or you just enjoy keeping up with real-world events, you can use the banners to any of the featured prediction platforms on this page, sign up, and try a few markets to get a firsthand experience.
