That’s a fantastic credit limit.
FYI: Usually if you get a second one of their top level cards the credit limit is 2 or 3 times what the first one was. You have to wait six months and then keep checking the prequal again. Savor or the regular Quicksilver NOT the Quicksilver One (if those cards would be helpful to you that is). Who knows you might find others cards more to your liking by then anyway.
