⚠ One Generation of Lock-In, Then a Clean SlateModerate threat

Qualcomm (QCOM) — threat to the moat

Lock-in worth exactly one product generation, renewed annually at a cost of nine billion dollars a year.

Switching costs that bind for one product cycle are switching costs that expire on schedule.

The cost of staying eligible for the next socket rose 68% in six years.

A handset maker that has designed a phone around Snapdragon cannot change it mid-programme; the board, thermals, camera pipeline, software and carrier certification all assume the part.1 That is real, and it is worth exactly one generation. At the next architecture selection, eighteen months to three years later, the slate is clean and Qualcomm competes again on price and product.

The cost of showing up to that competition is the research line: $9,042 million in fiscal 2025, about a fifth of revenue, rising to 26% of a smaller revenue base in the June 2026 quarter.2

The compounding risk is that a customer who ships one generation on a rival's silicon has already paid the switching cost. The second decision is free, and the third is habit.

There is no disclosure that would give warning. A lost socket becomes visible when the product it was in stops shipping.

The forward-looking number is R&D as a share of revenue, which is the price of remaining eligible.
