Question About $1,000 Upfront Fee for Coinbase Prime

Yesterday, I registered for a Coinbase Prime account and received an email requesting a $1,000 upfront fee. This seems unusual to me, as I’ve found mixed information online—some say there is an upfront fee, while others (including the Coinbase Help Center) indicate that there isn’t any upfront fee for opening an account.

Has anyone else experienced this? Can someone confirm whether this fee is legitimate or if there might be something off here?
