Analysis
Custom AI chips are forecast to grow at nearly double the rate of merchant AI accelerators like Nvidia's GPUs over the next seven years, according to Bloomberg Intelligence, which projects a 27% compound annual growth rate for custom silicon through 2033 against 16% for merchant accelerators -- a structural shift in who eventually captures the AI buildout's chip margins.
Broadcom is the company best positioned to benefit: it designs custom application-specific integrated circuits (ASICs) for Alphabet and Meta, letting the two hyperscalers build silicon tuned precisely to their own AI workloads rather than buying Nvidia's general-purpose GPUs at whatever margin the market will bear. That arrangement gives both companies a path to reducing their single-vendor dependence on Nvidia over time.
Nvidia's position is not under immediate threat -- it still holds an estimated 81% share of the overall AI chip market, and its Blackwell architecture remains sold out through mid-2026 -- but the growth-rate gap is exactly the kind of forward-looking signal that has driven AMD and Micron's stock performance far ahead of Nvidia's this year, even as Nvidia's own revenue keeps setting records.
“That arrangement gives both companies a path to reducing their single-vendor dependence on Nvidia over time.”
The logic follows a pattern seen across other parts of big tech: once a customer's scale justifies the fixed cost of custom silicon design, owning the chip becomes cheaper than renting it indefinitely from an external vendor, the same reasoning that has pushed Amazon, Microsoft and Google to build their own in-house AI chips (Trainium, Maia, TPUs) alongside their continued Nvidia purchases.
For semiconductor and infrastructure investors, the split to watch is between Nvidia's near-term fundamentals, which remain excellent by any conventional measure, and its long-term share trajectory, which the custom-silicon growth rate suggests will erode gradually as more hyperscalers reach the scale needed to justify their own chip programs.
What to watch: whether Broadcom's custom-ASIC relationships expand beyond Alphabet and Meta to additional hyperscalers, and whether Nvidia's own next-generation architecture roadmap is enough to keep its 81% share from eroding faster than the 2033 forecast currently implies.
