Yeah, I think all arbitrage setups of any kind are already being exploited by those with a hard to replicate edge (nano second execution/latency, very very deep pockets - typically your large market makers like Citadel). Just think about it: Jim Simons (RIP) had been doing it for longer than most of us have been alive.

Pretty soon AI won’t be optional, it’ll be the only way to run a profitable quant shop.
