The Samsung Galaxy Fold, the foldable smartphone the Korean company unveiled yesterday, is ‘the main potential challenge’ for Apple, says Goldman Sachs.

The bank – which is partnering with Apple in the launch of a new credit card later this year – believes the Fold could prove troublesome for Apple in two ways …

First, there’s the fact that Apple has so far led the flagship smartphone market, and Samsung now has a model which sits above the top-spec iPhone in both features and pricing. Business Insider saw the investment note from the bank.

Second, if Apple decides to launch its own folding phone, Samsung may not be willing to make the displays – for a while at least – and right now there’s no other supplier able to do so.

Apple has been taking significant steps to bring at least one other OLED supplier into the mix, even going so far as to bankroll LG’s capital costs in gearing up for flexible OLED production.

The supply issue may not be a barrier in practice. As I observed yesterday, Apple is unlikely to want to rush into the foldable phone market until it’s able to deliver a polished product – which the Galaxy Fold definitely isn’t.

Samsung currently dominates smartphone-sized OLED panel production, with a market share of around 95%. The company is seeking to further strengthen its lead by building the world’s largest OLED production plant.

A separate investment note, this time from Wedbush analyst Daniel Ives, suggests that Apple is at a critical point with the development of its streaming video service, expected to be announced (if not launched) next month. It’s simply not possible for the company to develop its own content at a sufficient pace to keep pace with existing services, he argues.

“While acquisitions have not been in Apple’s core DNA, the clock has struck midnight for Cupertino,” he said. “Building content organically is a slow and arduous path, which highlights the clear need for Apple to do larger, strategic M&A around content over the coming year to ‘double down’ and drive the services flywheel.”
