The bill of materials for Apple's iPhone 18 Pro is set to jump by roughly 38 per cent year-on-year, driven almost entirely by memory pricing. Research firm TrendForce estimates that memory's share of total BOM cost for the 256 GB model has climbed from about 10 per cent a year ago to roughly 34 per cent in the third quarter of 2026, with a further rise past 40 per cent projected for the first half of 2027. Memory has overtaken both the application processor and the display as the single largest cost component in Apple's flagship — a reversal from every prior generation. It has become the load-bearing wall of the smartphone bill of materials.This shift carries consequences far beyond Cupertino. Apple sits atop the smartphone industry with gross margins that most hardware makers can only dream of. If even Apple faces a margin squeeze of this magnitude, the rest of the market faces a bloodbath.About The AuthorAt heart, I am a storyteller drawn to the watershed moments that bend the technology landscape.
