What happened
Broadcom reported that its AI semiconductor revenue increased 221% year-over-year to $16.7 billion in the fiscal third quarter. The company guided for $21.7 billion in AI revenue for the fourth quarter and updated its long-term outlook to expect $230 billion in AI chip revenue by fiscal 2028.
According to The Motley Fool, Broadcom released its fiscal third-quarter earnings on September 2, 2026, revealing that AI semiconductor revenue reached $16.7 billion, a 221% increase from the previous year. CEO Hock Tan stated that demand for custom AI accelerators and networking remains very strong, with the company expecting AI revenue to accelerate to $21.7 billion in the fourth quarter.
The company updated its long-term financial outlook, now projecting that AI chip revenue will reach $230 billion by fiscal 2028. This figure is substantial compared to Broadcom's total trailing-12-month revenue of $89 billion, highlighting the central role of AI infrastructure in the company's future growth trajectory.
Broadcom's growth is driven by its role as a design partner for major AI players. The source notes that Broadcom is developing Tensor Processing Units (TPUs) for Google, custom inference chips for OpenAI, and MTIA accelerators for Meta. Tan indicated that Broadcom plans to deliver tens of billions of dollars worth of TPUs annually to Alphabet alone over the coming years.
Why it matters
This report confirms that custom AI silicon is becoming a dominant revenue driver for major semiconductor firms, with Broadcom serving key hyperscalers like Google, OpenAI, and Meta. The scale of the projected revenue indicates a sustained, massive capital expenditure cycle in AI infrastructure that extends well beyond current market expectations.
The report underscores the shift in the semiconductor industry toward custom AI silicon, where Broadcom is a primary beneficiary. The 221% growth rate demonstrates that the demand for specialized AI hardware is outpacing general-purpose chip sales, validating the massive capital expenditures by hyperscalers.
With a projected $230 billion in AI revenue by fiscal 2028, Broadcom is positioning itself as a critical infrastructure provider for the AI era. This level of revenue concentration in a few key customers, such as Google and OpenAI, suggests that the success of these AI companies is directly tied to Broadcom's financial performance.
The article highlights that despite the strong growth, the stock's valuation remains relatively modest at 12 times fiscal 2028 earnings, compared to 25 times for other leading chip stocks. This suggests that the market may be undervaluing the company's long-term potential if the AI build-out continues as projected.
What to watch next
Investors should monitor Broadcom's ability to secure memory supply to meet demand, the actual ramp-up of Ironwood TPU shipments to Anthropic, and whether the stock's valuation multiple expands to match the growth rates of other leading chipmakers.
Supply chain constraints, particularly in memory components, could impact Broadcom's ability to meet its aggressive revenue targets. Management claims to have secured necessary supply, but component shortages remain a risk to the projected growth.
The actual shipment ramp of the Ironwood TPU version 7 to Anthropic in the fourth quarter will be a key indicator of whether Broadcom can maintain its momentum in the custom AI chip market.
Regulatory and public sentiment regarding data center construction and energy consumption could influence the pace of AI infrastructure spending, potentially affecting the demand for Broadcom's products in the long term.
