Who uses custom sports betting products?

Background The expansion of online gambling in the UK has been accompanied by an increase in the number of novel betting products, particularly for soccer. The present research investigates which types of sports bettors are the most likely to use novel gambling products called 'custom sports bets' (CSBs), which allow gamblers to create their own unique bets. Method A large-scale, cross-sectional survey of online sports/horse racing bettors (n = 789, 32.7% female). The survey collected two measures of CSB usage and four validated gambling measures: the Problem Gambling Severity Index, the Gambling Related Cognition Illusion of Control Scale, the Short Gambling Harm Screen, and the Consumption Screen for Problem Gambling. Results Overall, 62.0% of participants reported having used a CSB, and those who had used a CSB did so on an average of 29.4 days over the last year. Overall, 16.0% of participants who had used a CSB were current problem gamblers, compared to 6.7% among those who had not. CSB users reported an average of 2.3 out of 10 possible gambling harms, compared to 1.5 harms for those who had not used a CSB. The illusion of control scale was significantly positively correlated with whether participants had ever used a CSB before, but not with past-year frequency of CSB usage. The usage of CSB products was most strongly associated with the frequency of gambling consumption. Conclusions Overall, these findings suggest that CSB products raise distinctive concerns around consumer protection for frequent sports bettors which deserve further investigation.
