⚠ The Function Gets Integrated AwayModerate threat

The 'small cost, big consequence' advantage assumes the function stays a discrete chip that Broadcom supplies — but the long history of semiconductors is one of discrete functions being absorbed into larger, more integrated chips over time. What is a separate, high-margin Broadcom component today can become a block integrated into a customer's system-on-chip tomorrow, eliminating the socket entirely. Integration is the quiet, permanent enemy of every specialized chip vendor.

The threat is sharpest with Broadcom's largest, most sophisticated customers — the hyperscalers and system makers who have the scale and engineering talent to pull functions in-house. A cheap-but-critical part is exactly the kind a giant customer might decide is worth designing itself, both to capture the margin Broadcom earns and to control its own roadmap. Each function integrated away removes a durable, profitable stream that is hard to replace. Apple, which designs its own chips, took about 20% of Broadcom's revenue in each of fiscal 2022 and 2023¹.

Broadcom's defense is to keep its parts at the leading edge of performance, where integrating them in-house is hardest and least worthwhile, and to keep moving up to new critical functions as old ones commoditize. That has worked for decades, but it is a treadmill, not a moat that holds by itself: the company must continually justify why its specialized silicon beats what a customer could build alone. A slow, persistent pressure rather than a sudden threat — and it falls hardest exactly where Broadcom's biggest revenues sit, the AI silicon that brought in $16.7 billion in the quarter to August 2026².
