https://www.fdic.gov/analysis/quarterly-banking-profile/qbp/... claims that there were 4,706 banks reporting to FDIC at the end of last year. If anything there are too many banks and too few big internet companies, given that you can fit the five that matter into one acronym.
I’m not sure it’s fair to compare regional banks to FAANG if that’s what you mean? There are plenty of “internet” companies that don’t fit into FAANG just as there are only a few mega banks on the scale of FAANG. Or I misunderstood?
