Apple has cap­tured Gen Z in the US so thor­oughly that younger con­sumers fear being socially ostra­cised for not hav­ing an iPhone, a trend that will allow the tech group to gain mar­ket share across mul­tiple product cat­egor­ies.

The tech group's hold on younger con­sumers marks a sig­ni­fic­ant change as mar­ket research has shown that, for older gen­er­a­tions of Amer­ic­ans, there is a rel­at­ively even split between own­ers of devices run­ning Android, Google's soft­ware for mobiles, and Apple's iOS.

Shan­non Cross, ana­lyst at Credit Suisse, said the rami­fic­a­tions of these shift­ing tastes exten­ded well bey­ond smart­phones, as iPhone users were more likely to pur­chase Mac­Books, Apple Watches and Air­Pods.

'The strength of the Apple eco­sys­tem cre­ates a moat that is fairly impen­et­rable by the com­pet­i­tion,' Cross said. 'It really makes it hard to change the tra­ject­ory. Apple is just going to con­tinue to gain share over time.'
