Methods

Using matched pair analysis and other methods (e.g., regression), we examined big wins’ ability to predict future gambling involvement and behavior using bet level data from 36,328 sports gamblers who subscribed to a large, European online gambling operator. Big wins were defined two ways.

Results

Big wins in sports betting were associated with increased engagement, losses, and risk in the following weeks, with the impact declining over time. The exact timing of when a big win occurs after subscribing does not appear to have a major effect on subsequent behaviors. These findings held for both definitions of big wins.

Implications

This study supports the existence جت بت of a big win effect in online sports betting, but more research is needed to determine whether there is an “early” big win effect, and whether big wins are indeed associated with problematic gambling.
