What is a Prediction Market? Key Takeaways Prediction markets are markets that bet on the occurrence of events in the future.
They are used to bet on a variety of instances and circumstances, from the outcome of presidential elections to the results of a sporting event to the possibility of a policy proposal being passed by legislature.
Prediction markets depend on scale; the more individuals participate in the market, the more data there is, and the more effective they become.
Compare Accounts. Prediction markets may also be subject to speculative bubbles. There can also be direct attempts to manipulate such markets.
In the Tradesports presidential markets there was an apparent manipulation effort. An anonymous trader sold short so many Bush presidential futures contracts that the price was driven to zero, implying a zero percent chance that Bush would win.
The only rational purpose of such a trade would be an attempt to manipulate the market in a strategy called a " bear raid ". If this was a deliberate manipulation effort it failed, however, as the price of the contract rebounded rapidly to its previous level.
As more press attention is paid to prediction markets, it is likely that more groups will be motivated to manipulate them.
However, in practice, such attempts at manipulation have always proven to be very short lived. In their paper entitled "Information Aggregation and Manipulation in an Experimental Market" ,  Hanson, Oprea and Porter George Mason U , show how attempts at market manipulation can in fact end up increasing the accuracy of the market because they provide that much more profit incentive to bet against the manipulator.
Using real-money prediction market contracts as a form of insurance can also affect the price of the contract. For example, if the election of a leader is perceived as negatively impacting the economy, traders may buy shares of that leader being elected, as a hedge.
These prediction market inaccuracies were especially prevalent during Brexit and the US Presidential Elections. Even until the moment votes were counted, prediction markets leaned heavily on the side of staying in the EU and failed to predict the outcomes of the vote.
According to Michael Traugott , a former president of the American Association for Public Opinion Research , the reason for the failure of the prediction markets is due to the influence of manipulation and bias shadowed by mass opinion and public opinion.
Similarly, during the US Presidential Elections, prediction markets failed to predict the outcome, throwing the world into mass shock.
Like the Brexit case, information traders were caught in an infinite loop of self-reinforcement once initial odds were measured, leading traders to "use the current prediction odds as an anchor" and seemingly discounting incoming prediction odds completely.
Because online gambling is outlawed in the United States through federal laws and many state laws as well, most prediction markets that target US users operate with "play money" rather than "real money": they are free to play no purchase necessary and usually offer prizes to the best traders as incentives to participate.
Notable exceptions are the Iowa Electronic Markets , which is operated by the University of Iowa under the cover of a no-action letter from the Commodity Futures Trading Commission , and PredictIt , which is operated by Victoria University of Wellington under cover of a similar no-action letter.
Some kinds of prediction markets may create controversial incentives. For example, a market predicting the death of a world leader might be quite useful for those whose activities are strongly related to this leader's policies, but it also might turn into an assassination market.
