Prediction market

A prediction market is an online tool that lets people show how likely they think certain things will happen. For instance, a prediction market might let you bet on who will win the next election, what the weather will be like, or even how the stock market will do. People use money to make their bets, and the person who guessed correctly will get that money. It's a way to make money off of predicting the future!
