What is a prediction market?

Prediction markets allow users to purchase shares relating to the outcome of events using real money. Each event, such as an election, has a number of contracts associated with it, each correlating to a different outcome. For instance, an election contested between four candidates would be represented by eight separate contracts, with each contract correlating to a particular candidate winning or losing the election.

The share price in each individual forecast rises and falls based on market demand. Once the event's outcome is decided, holders of shares that correlate with the correct outcome receive a payout for each share they held.

For example, a user buys 10 shares at 20 cents each in a presidential primary saying Candidate A will win. If Candidate A wins the election, the user earns $10. If the candidate loses, the user earns no money and loses his original $2 investment.

Why do prediction markets matter?

Prediction markets can be used to gain insight into the outcome of elections. Microsoft Research economist David Rothschild argued that they are better suited to the task than polls: "I can create a poll that can mimic everything about a prediction market...except markets have a way of incentivizing you to come back at 2 a.m. and update your answer."[1][2][3]
