Broadcom's fiscal third quarter showed AI semiconductor revenue more than doubling to $16.7 billion, yet shares slipped after the company forecast $34.8 billion in fourth-quarter revenue that barely cleared the consensus bar. The quarter itself was a blowout: total revenue jumped 86 percent year on year to $29.6 billion and adjusted earnings of $3.32 a share beat the $3.22 estimate. But the market had already priced in a miracle, and the guidance felt like a mere mortal result.
The AI engine is real
Custom accelerators and networking chips for OpenAI, Google, Anthropic and soon Meta drove AI semiconductor revenue up 221 percent from a year earlier. Broadcom now sees that line hitting $21.7 billion in the current quarter, a 236 percent year-on-year surge. Management says it has visibility into major deployments running through 2028, a claim that usually belongs in a slide deck but here comes with named customers and a growing order book.
The $230 billion horizon
The company put a staggering number on the whiteboard: $115 billion of AI semiconductor revenue in fiscal 2027, potentially doubling again to around $230 billion in 2028. That trajectory assumes hyperscalers keep converting capital budgets into silicon at the current clip. If they do, Broadcom becomes the primary toll collector on the AI infrastructure build-out. If they pause, the multiple compresses fast.
Expectations ate the upside
The stock's reaction tells the story. Beating estimates on the top and bottom lines was not enough because the whisper number had migrated far above the published consensus. A $34.8 billion Q4 forecast that sits "only slightly above or below some analyst estimates depending on the data set" is code for: the bar was set in the stratosphere and the company merely cleared it. Investors are now asking whether the 2027 and 2028 targets are a floor or a ceiling, and whether the next quarter can deliver a guide that feels like a step change rather than a continuation.
