Well, I don’t know much about market making but as a member of Gamblers Anonymous since 1998 I’ve seen just about every kind of devastation caused by every kind of gambling. In the last few years I’ve seen a significant increase in the number of very young men coming to us. Here in Australia, the gambling industry absolutely is laser focused on targeting young men using every psychological trick in the book, including such pernicious features as “Bet With Mates (tm)” which is explicitly designed to use peer pressure to lock in and escalate those in the group who may otherwise pull out.

If we accept that almost 50% of revenue comes from 80% of gamblers (a diverse cohort) while the other almost 50% comes from 3% of gamblers (a far more uniform cohort), then of course betting companies would be absolutely defending against any change (regulation) that would impact the 3%. Furthermore they’d be remiss in their duty to their shareholders if they weren’t trying to migrate gamblers from the larger cohort to the smaller.
