Apple has entered the foldable market at the top of it. iPhone Duo, announced in Cupertino on 9 September, starts at US$1,999 with 256GB and goes up to 2TB — above the US$1,899 Samsung charges for the wide-format Galaxy Z Fold8 — and is priced as a halo product rather than a volume one. The interesting question is not whether Apple can sell it. It is who gets to build it, and how few of them there are.
