Micron’s cheaper valuation fuels case it could outpace Broadcom in AI growth

Two chipmakers are riding the same AI spending wave. They are priced very differently.

Micron Technology trades at forward price-to-earnings multiples of roughly 6-13x. Broadcom sits around 18-30x. That gap sits at the center of a question The Motley Fool recently put to investors: which of these two semiconductor names is the better AI buy over the next three years?

The case for Micron: memory is the bottleneck

Micron leads in high-bandwidth memory, or HBM, plus the DRAM and SSD storage that fill data centers.

Micron reported fiscal Q4 2026 revenue of $54.2 billion, a 379% jump from the same quarter a year earlier. Full-year fiscal 2026 revenue came in at $133.2 billion, up 256%.

Micron guided for Q1 of fiscal 2027 revenue of $61.5 billion, give or take $1.5 billion, with expectations of sequential revenue growth throughout fiscal 2027.

The company also raised its long-term supply commitments to $32 billion. Tight supply conditions in memory are expected to persist through 2028, according to the research findings on the company.

Analyst consensus on Micron is a Strong Buy, with a potential price target upside of about 60% based on late September figures.

The case for Broadcom: customers who aren’t going anywhere

Broadcom builds custom chips and solutions tailored to specific tech giants. Its customer roster includes Google, Meta, OpenAI, and Anthropic.

Broadcom reported AI semiconductor revenue of $16.7 billion for fiscal Q3 2026, up 221% year over year.

Broadcom has projected AI semiconductor revenue of about $115 billion for fiscal 2027 and about $230 billion for fiscal 2028. Broadcom also carries a Strong Buy consensus rating from analysts.

Why the valuation gap exists

Micron’s low multiple reflects investor concern that today’s HBM shortage eventually eases. If tightness really does hold through 2028, that skepticism could prove too cautious. Broadcom’s higher multiple reflects its custom chips built for specific customers that are harder to swap out, and multi-year partnerships with hyperscalers offer visibility that spot memory pricing cannot.

What this means for investors

Broadcom’s fiscal 2028 target of about $230 billion leaves little margin for disappointment, and stocks trading at higher multiples tend to react sharply when growth slows. Micron’s guidance range of plus or minus $1.5 billion for its next quarter is a reminder that even strong forecasts come with uncertainty.

The key checkpoints are quarterly earnings. Watch whether Micron delivers the sequential growth it has promised through fiscal 2027, and whether its long-term commitments keep climbing past $32 billion. On the Broadcom side, the signal to track is progress toward that roughly $115 billion fiscal 2027 AI revenue target.

Micron offers the cheaper ticket with more sensitivity to the memory cycle. Broadcom offers predictability, at a price that already assumes things go very well.
