Online sports wagering is a popular and still growing gambling activity around the world. Like other types of gambling, it can lead to problems that include devastating financial, social, and health-related harms. The first analysis of actual online sports wagering activity (LaBrie, LaPlante, Nelson, Schumann, & Shaffer, 2007) suggested that levels of financial and time involvement were more moderate than anticipated from earlier survey studies. However, these findings are now more than a decade old. The current study examined actual online sports wagering activity of a similar cohort of 32,262 online gamblers from 2015 to understand how sports betting might have changed in ten years. Measures included subscriber characteristics, betting activities, and transactional activities. Online sports wagering behavior was similar to what was found a decade ago, with the majority of subscribers exhibiting modest to moderate, and a small subset exhibiting disproportionately high engagement, transactional activity, and in-game betting. These findings suggest that further investigation of individual trajectories of sports wagering behavior and engagement with different types of sports wagering products is merited.
