Understanding Prediction Markets

A prediction market is a platform that focuses on speculating the outcomes of various events in different industries. Instead of traditional markets that involve speculating on asset prices, prediction markets allow individuals to speculate on the results of events such as election outcomes, sports events, and contests. In recent times, prediction markets have even witnessed unusual predictions like the color of an outfit during a US presidential speech or the number of coronavirus cases.

Some prediction markets use the parimutuel system, where participants support different predictions and place their bets into a common pool. The winning prediction then takes the entire pool of bets and distributes it proportionally among the participants based on their share of the winning stake. In such cases, the organizer of the prediction market takes a small commission from the pool.

Due to the need for evaluating predictions from a large number of individuals, prediction markets rely on significant sample sizes. The more participants there are, the more data is available, leading to more accurate predictions.

Many modern prediction markets leverage blockchain technology to offer various incentives that encourage people to bet on predictions. Some common strategies or mechanisms include:

The reputation score of participants improves if their predictions align closely with the actual outcome, increasing the impact of their future predictions on their winnings.
If a prediction differs significantly from the “crowd wisdom,” the payout for a correct prediction is higher.
Early predictions, when there is insufficient data available, receive a higher time weight in the calculation of winnings.
