The latter. I saw an email thread go around to organize a betting pool, using venmo (with the obvious warning not to say it was for gambling in the memo) and had a huge "ah ha" moment for why that feature exists. It's perfect for ensuring collections & payouts happen correctly and no money goes missing, or "missing". It'd be hard to crowd source for better odds on there, I'd think, since people disguise those kinds of transactions. Same as with drug purchases, which are also prohibited on Venmo so you can't mention them but are, obviously, some part of the activity on there, though unlike with betting pools Venmo's (previously, to me) weird social ledger thing isn't a killer feature for that. Probably they could spot betting pools and put some rules in place to make it annoying enough to use the platform for that purpose that people would stop, though I don't know why they would. I'd guess illegal activity's far from a majority of their revenue, but I bet it's still significant. Probably certain transaction patterns get really common on either side of major sports events.
