Broadcom's AI chip revenue growth rate has more than doubled since January -- and its CEO just put a $230 billion number on 2028

$16.7B (Broadcom's AI semiconductor revenue this quarter, up 221% from a year earlier) Broadcom posted fiscal third-quarter results on September 2 built around one number: $16.7 billion in AI semiconductor revenue, up 221% year-over-year and 54% from the prior quarter, against total revenue of $29.6 billion. The result beat the roughly $16 billion guidance Broadcom itself gave three months earlier, and it did so while the growth rate was still climbing rather than leveling off.

That climb has now held for three straight actual quarters, with a fourth already guided higher. AI semiconductor revenue went $8.4 billion in Q1 (up 106% year-over-year), $10.8 billion in Q2 (up 143%), then $16.7 billion in Q3 (up 221%) -- each quarter's year-over-year growth rate higher than the one before it, not just its dollar total. That is an acceleration curve, not a growth curve, and it is the specific pattern Tan pointed to on the call as evidence the current run isn't cresting yet.

Broadcom is guiding to $21.7 billion for the fourth quarter, which would put full fiscal-2026 AI semiconductor revenue at roughly $58 billion. Tan then went past the current year entirely, telling analysts Broadcom already has the supply secured -- meaning wafer capacity and packaging booked, not just customer demand -- to hit roughly $115 billion in fiscal 2027 and $230 billion in fiscal 2028, about four times this year's total. "Demand actually exceeds this outlook," he said of the $230 billion figure -- an unusual thing for a chipmaker to volunteer about a target two years out.

The AI semiconductor line isn't the whole company. Broadcom's infrastructure-software business, mostly VMware, kept growing at a steadier pace on the same call, giving the company a non-AI floor that a pure-play accelerator startup doesn't have if the cycle turns. That mix cuts the other way too: Tan has previously flagged that AI semiconductors carry thinner margins than Broadcom's networking and software lines, so the fastest-growing part of the business is also, by his own account, the part diluting the company's overall gross margin.

Underneath both multi-year targets sits a concentration Broadcom keeps volunteering rather than hiding: nearly all of that revenue runs through just six custom-chip customers, and Tan says only two of them need outside help paying for it.

“Anthropic and OpenAI are like two geniuses in the middle of Mongolia” who need financing to reach their potential -- Hock Tan, Broadcom CEO

That financing mostly runs through a platform Broadcom launched in June with Apollo Global Management and Blackstone, built to fund customers' chip and data-center buildouts off Broadcom's own balance sheet. Its first tranche, $35 billion, has already closed and is earmarked for Anthropic, which Tan said is on track to pass Google as Broadcom's largest custom-chip customer sometime in 2027. Reporting in late August put the same platform in talks to grow toward $100 billion for Anthropic's buildout alone -- nearly triple that first close, though no party has confirmed a final figure. (Broadcom helping arrange financing for the customer that then spends it on Broadcom's own chips is not new in this industry, but it does mean some of the "demand" behind the 2028 target is demand Broadcom itself is helping create.)

Tan put a number on why that financing is worth arranging: each gigawatt of AI compute a customer like Anthropic or OpenAI deploys, he told analysts, can generate roughly $30 billion a year in Broadcom revenue over the life of the contract. That math is Tan's own explanation for why a chipmaker would help arrange financing for its customers rather than just wait for a purchase order: locking in the compute now locks in the chip revenue that compute requires for years afterward, regardless of who ultimately fronts the cash for the buildout. It also explains why Broadcom is willing to compete for a customer relationship years before the matching revenue shows up on an income statement -- the up-front financing is itself a way of winning the order against rival accelerator suppliers, not just a courtesy extended after the sale.

Broadcom's stock barely moved on the results despite the beat. The reason was narrower than the AI story: $34.8 billion in guided Q4 total revenue landed a shade under the roughly $35 billion analysts wanted, enough on its own to offset an otherwise clean quarter. That gap sat entirely in the parts of the business the AI numbers don't touch -- a reminder that a record AI print and a flat stock price aren't a contradiction once the rest of a $30-billion-a-quarter company is counted too.

Nothing about today's print changes what a customer of Broadcom's non-AI business sees. What changed is the shape of the bet the company is now making in public: three straight quarters of accelerating growth, a fourth already guided higher, a two-year target built on financing arrangements Broadcom itself helps structure, and a CEO willing to say on the record that demand already exceeds even a $230 billion outlook -- a claim that, like the outlook itself, nobody outside Broadcom has independently checked. The next real checkpoint isn't another quote on a call; it's whether $21.7 billion actually shows up in December.
