alt Hacker NewsOutside of the US where gambling on sports has been the norm for decades, the bookies tend to run square books and just earn spread + commissions. To the point where pvp exchanges have been the dominant destination for betting for 20 years or so.
These article (and others like it recently) just make me think US sports betting operations are operating on antiquated business model.

All the tech piling into US sports books is British precisely because the British markets (particularly horses, football and tennis, but really everything up to and including political markets) are so much more sophisticated and there's a killing to be made exploiting the rubes in the Wild West.
Really professional gamblers (eg Tony Bloom / Betlizard) are just hedge funds and what we're talking about in this thread is "trying to gain an execution edge".
Yes, this is only because american sports give "line bet" and "prop bets", that anybody can exploit if two apps aren't coordinated. You can do line arbitrage (middling is the easiest, but professionals use props with weird maths and specific knowledge to make a living).
If you only offer to bet on the money line, it makes it way harder for professional gamblers.
