Prediction Markets

Prediction markets are marketplaces for the exchange of predictions on uncertain future events. While stock exchanges find the price of stocks and futures markets find the price of commodities, prediction markets find the probability of some real world event happening. Traders buy or sell shares based on their predictions of the event happening.
