Bloomberg's Mark Gurman noted on X (Twitter) today that Otterbox is already selling iPhone 18 Pro cases at Best Buy. While the timing is early for a new iPhone that isn't expected until September, what's more interesting is that Otterbox's packaging indicates the iPhone 18 Pro will fit iPhone 17 Pro cases and vice versa.

Gurman passed on the packaging detail without saying whether he agrees with the implied sizing, and rumors suggest the iPhone 18 Pro lineup will largely retain the same design as the iPhone 17 Pro models. However, at least two leakers have claimed that the iPhone 18 Pro Max could be thicker and heavier than its predecessor, owing to its larger battery.
