A look at Apple's quest to build key device components in-house, including a cellular modem and other wireless chips, displays, batteries, and camera sensors
Context & Ripple Effects
Apple's component push builds on an earlier decision to place modem engineering under Johny Srouji's hardware-technology organization and a 2020 effort to develop a modem intended to replace Qualcomm's chip. It extends the same internal-silicon playbook covered in Apple's multiyear replacement of Intel processors in Macs.
The breadth of the effort matters: modem, wireless, display, battery and camera work would shift more of the device bill of materials from supplier-selected parts toward Apple-controlled engineering roadmaps. Later coverage indicates the in-house modem remained a multiyear rollout effort, underscoring the execution difficulty.
First-order effects
- Apple must sustain specialized engineering programs across several component categories, concentrating more product-definition responsibility inside its hardware organization.
- Existing component suppliers retain their roles while Apple develops alternatives, but face a clearer risk that future design wins and roadmap influence migrate in-house.
Second-order effects
- Suppliers in affected categories may need to differentiate through manufacturing scale, component performance, or support for Apple-specific designs rather than rely on long-lived standard-part positions.
- Apple can coordinate component choices more tightly with its devices and software if internal projects reach production, while delays preserve suppliers' leverage and create parallel development costs.
Third-order effects
- If this pattern holds, premium device makers will increasingly treat custom components as a strategic control point, not merely a procurement decision—raising the value of scarce chip and systems engineering talent.
- The outcome is likely to be uneven rather than a wholesale exit from suppliers: difficult components such as cellular modems can keep external partners relevant even as vertical integration expands elsewhere.
The trend: Apple's component program is one instance of device makers using custom silicon and adjacent in-house hardware to control differentiation, supply dependencies, and product roadmaps.
