Abstract
Prediction markets are a powerful tool to make accurate predictions about the outcome of an event and, for this reason, they attract the interest of researchers and practitioners alike. To date, there exist no means of validation for quantitative models of prediction markets. To address this shortcoming, in this paper we compile a list of empirical regularities (stylized facts) of price changes we find by analyzing daily price changes from 3385 prediction markets on political events, a dataset provided by PredictIt. We find that price changes in prediction markets show characteristics similar to emerging markets, with some small differences.
