Abstract: The aim of this paper is to predict the fair price as accurately as possible from the
microstructure of the orderbook on Betfair, the world's largest betting exchange. In particular,
the work focuses on the analysis of the effect of disproportionately large quotes on the fair
price of the market. It also addresses their theoretical monetization in practice in the case of
market inefficiency. The results show that, from the data examined, traded markets are
relatively efficient and the factors that can be inferred from the microstructure of the
orderbook are, in the vast majority of cases, not statistically significant for predicting the fair
price of a given event. However, the data do show exceptions where, in particular types of
markets, these quotes are statistically significant and have the expected impact on the model's
prediction in the form of increasing the probability of the selection they want to trade. Thus, the
model prediction can in some cases be used as a fair price indicator by which one could
theoretically trade profitably on Betfair or even on other platforms, assuming they offered a
better price.
