Prediction markets let you buy and sell contracts on real-world markets, such as pop culture. While they may seem similar to sports betting or other forms of gambling, they function more like financial exchanges because you buy contracts, and prices move based on public perception. Find out all the must-know details about prediction markets: how to get started, whether they’re safe, and which sites are the best.
Here’s a quick look at the top six prediction market sites, including the pros and cons of each one.
Prediction markets are platforms where people trade on the outcome of real-world events. Instead of placing a fixed-odds bet with odds set by the house, you’re buying and selling contracts whose prices reflect what the market (including other predictors) thinks will happen. As news breaks and opinions shift, prices update to incorporate that information.
Most prediction markets simplify outcomes to “Yes” or “No,” making them approachable for beginners. The price you pay represents the market’s current implied probability of that outcome.
Other markets may have multiple possible outcomes (for example, who will be TIME magazine’s person of the year). In these cases, you can pick from a list of contenders, each with its own probability of winning.
Here are the quickfire need-to-know details about how prediction markets work. As they are new to the US market, it’s vital to understand the differences between online casino play and prediction markets.

Those prices are per contract, and you can buy multiple. If your outcome is correct, you get $1 per contract. You can also sell your contracts at a later date. This might be a good idea if the outcome has become more likely, but you still have some uncertainty and want to guarantee a payout.

If you’re new to prediction markets, I suggest starting small and simple. Stick to Yes or No markets and only buy a few dollars' worth of contracts at a time. This will help you get the feel for how it all works.
Signing up for a prediction market site usually takes just a few minutes. Note that the steps may change slightly between sites, but the overall process will feel similar at any prediction platform.
Prediction markets occupy a unique regulatory space and are governed more like financial sites. That’s why you’ll see language like “trade” and “contracts” instead of more gambling-coded words.
So, while prediction markets aren’t regulated in the same way as US online casinos or sportsbooks, they are still subject to strict regulation at the federal and state levels. Most reputable prediction market sites will have authorization from the Commodity Futures Trading Commission.
That said, prediction markets are currently under a lot of legal scrutiny. Some states have banned them completely, and legality varies by jurisdiction.
