Note that JPM Chase had had “instant transfer” for about 2 years now. They appear the only one with it, and it likely is prototype/testing of this new system. They have it down to about 10 seconds now.
I can sit with a second bank account up in another browser tab, do the transfer from JPM Chase, and see it show up in the second account if I do a refresh after about 10 sec.
