AI demand accelerates into fall

Hyperscalers are pulling forward orders for custom accelerators, high-bandwidth memory, and networking chips. All three major semiconductor names raised guidance in recent earnings despite a mid-week tech selloff.

Broadcom's AI revenue surges 221%

Broadcom reported fiscal Q3 AI semiconductor revenue of $16.7 billion, up 221% year over year and now 56% of total revenue. Management projects AI revenue reaching $230 billion by fiscal 2028.

“Q3 demand was simply hot and we're just getting started.”

Broadcom's custom silicon pipeline widens

Management guided Q4 AI revenue to $21.7 billion and outlined a multi-year trajectory anchored by six named customers, including a Google TPU agreement and a 1.3 gigawatt OpenAI deployment planned for 2027.

Broadcom margin pressure ahead

Rising custom silicon mix is a margin headwind. Q4 consolidated gross margin is expected to be approximately 73%, compared with 78% a year ago, as memory content grows inside custom accelerators.

Micron's data center revenue explodes

Micron posted fiscal Q3 revenue of $41.46 billion, up 346% year over year, with data-center revenue exceeding $25 billion, an annualized run rate of over $100 billion.

Micron backs memory cycle with capex

Management guided fiscal Q4 revenue to $50 billion with 86% gross margin and outlined $27 billion in fiscal 2026 capex, with fiscal 2027 spending expected above Q4 levels. HBM4 is ramping twice as fast as its predecessor.

“AI has elevated the value of memory.”

Micron's customer lock-in is unusual

Sixteen Strategic Customer Agreements, mostly five-year take-or-pay contracts, cover roughly 20% of DRAM volume and a third of NAND volume, giving rare visibility for a memory maker.

Marvell raises data center growth outlook

Marvell raised fiscal 2027 data-center growth outlook to approximately 60% from 50% previously, with data center now 79% of total revenue. Management expects fiscal 2028 data-center revenue to grow more than 60% year over year.

“AI-related bookings remain exceptionally robust.”

Marvell's reset is broad-based

Growth spans interconnect, switching, custom silicon, optical DSPs, and scale-up networking. Marvell's expanded custom program with Google includes a warrant for Google to acquire up to 7% of shares tied to revenue milestones.

Micron's Q4 report is the next test

Broadcom has delivered its trajectory and Marvell has raised guidance. Micron's fiscal Q4 report, expected late September, will test whether hyperscaler capex is holding through year-end.
