What Are Prediction Markets? How Event Contract Trading Works

How do prediction markets work?

On prediction markets, you can trade event contracts tied to real-world events. These can be sports prediction markets, culture prediction markets, or any number of other categories. You, the customer, then have the option to buy and sell yes or no event contracts based on these predictions. This is done at prediction exchanges which facilitate the peer-2-peer trading of these predictions.

Let’s look at an example. One of the political prediction markets you might find could be, “Will any presidential candidate win outright in the first round of the Brazil election?” This question is the prediction market. Beneath that prediction market, you will then have a yes or no option such as:

  • Yes - 13c.
  • No - 89c.

These are the event contracts you can buy and sell for that prediction. Throughout the history of prediction markets and in most sites today, the settlement value of event contracts is typically $1, and their actual buy/sell price varies depending on user sentiment and which is seen as the most likely outcome.

If you buy a yes or no event contract relating to a prediction, you can then do two things with it:

  1. Sell it - if the price of the event contract shifts in your favor, you could potentially sell it to try and make a return.
  2. Hold it - if you are happy with your trade and think you have made the right prediction, you can hold your contracts until the event happens. At that point, if you got it right, you will get the settlement value of your event contract (usually $1), minus any fees.

When we look into what prediction markets are, these are the basics - crypto prediction market sites and other exchanges are simply the facilitators of these peer to peer trades. For more insight, we’ve listed some prediction examples we’ve previously seen in the table below, and you can also check out our prediction markets news page for general industry updates.

Prediction Market Yes No Exchange
Charlotte Hornets vs Miami Heat (Charlotte to win - NBA Play-In) 69c 32c Polymarket
Party to Control US House of Representatives in 2026 (Democrat) 83c 18c Crypto.com
Will the US confirm that aliens exist before 2027? 19.7c 80.5c Kalshi
Will Bitcoin be above $200k by next year? 9c 92c Kalshi
