Abstract

We analyse betting behaviour patterns of the visitors of the specialized betting website dedicated to the popular eSports game Counter-Strike: Global O ensive. The reverse favourite-longshot bias is found both in the in-sample and out-of-sample datasets. This phenomenon is rather unusual for parimutuel betting markets because favourite-longshot bias is more common. We de ne simple betting strategies based on the bets on underdogs and show that these strategies make a suciently large positive pro t, which is a sign of market ineciency. Next, we investigate determinants of the reverse favourite-longshot bias. We hypothesize that popular teams attract more unsophisticated gamblers which adds to the stronger reverse favourite-longshot bias in matches with such teams. Geographical proximity is found to be a signi cant factor that increases the bias, whereas the e ect of internet popularity measured by the number of team players' followers on Twitter surprisingly follows the U-shape curve
