This guide explains what prediction markets are, how they work, and why they are increasingly used to forecast real-world events.
What Are Prediction Markets?
Prediction markets are systems where participants buy and sell shares linked to future events, with prices reflecting the probability of those outcomes.
For a broader overview of how these platforms operate, see our prediction markets guide.
How Prediction Markets Work
Users buy shares in outcomes they believe will happen. If the event occurs, the contract pays out. If not, it expires worthless.
Prices fluctuate based on supply and demand, reflecting real-time market sentiment.
