Broadcom earnings on September 2 expected to reveal $16B AI semiconductor quarter

Broadcom is about to put its money where its mouth is. When the company reports fiscal Q3 2026 earnings after the bell on September 2, investors will be looking for confirmation that its AI semiconductor business hit roughly $16 billion in quarterly revenue, a number that would represent more than 200% growth year-over-year.

The numbers Wall Street is watching

Broadcom’s own guidance pegs total revenue for the quarter at approximately $29.4 billion, which would mark an 84% increase compared to the same period last year. The AI semiconductor segment is expected to carry the heaviest load, with that $16 billion figure serving as the headline metric investors will measure everything against.

The company enters this report with momentum. In Q2 FY2026, Broadcom posted record consolidated revenue of $22.2 billion, a 48% jump from the prior year. AI semiconductor revenue specifically came in at $10.8 billion, reflecting 143% year-over-year growth. The company also reported a record adjusted EBITDA margin of 69%.

For Q3, management has guided non-GAAP operating margin to roughly 67%. As Broadcom’s product mix tilts further toward custom silicon designed for hyperscaler clients, margins could face structural pressure even as top-line numbers soar.

Who’s buying and what they’re building

Broadcom’s AI semiconductor business is fueled by a client roster that reads like a who’s who of the AI buildout. Google (via Alphabet) relies on Broadcom for its TPU custom accelerators, the chips powering much of Google’s AI infrastructure. OpenAI, Anthropic, and Meta are also among the company’s key customers.

Networking products accounted for approximately 40% of AI semiconductor revenue in Q2, a reminder that Broadcom’s AI story isn’t purely about custom accelerators.

The full-year fiscal 2026 AI semiconductor revenue target stands at $56 billion, which management reaffirmed after Q2. That represents roughly 180% year-over-year growth for the fiscal year. Even more ambitious: the company has projected AI semiconductor revenue exceeding $100 billion for fiscal 2027.

Stock under pressure despite blowout growth

Broadcom’s stock has pulled back from 52-week highs near $495, recently trading in the $368 to $400 range. Investors have grown jittery about the sustainability of AI infrastructure spending, particularly around how hyperscalers are financing their massive buildouts. There’s also the margin question: custom silicon is a lower-gross-margin business compared to Broadcom’s traditional merchant chip products, and analysts will be parsing the Q3 numbers to see whether Broadcom is managing that tradeoff effectively.

What the September 2 report means for the broader market

Broadcom’s earnings carry implications well beyond its own stock price. The report will serve as a real-time health check on AI infrastructure demand from the world’s largest technology companies. A beat on the $16 billion AI revenue guide could stabilize sentiment across the tech sector. A miss, or cautious commentary about order backlogs and customer financing, would likely amplify existing concerns about the durability of the AI capex cycle.

The fiscal 2027 target of $100 billion-plus in AI semiconductor revenue looms large. Every quarterly report between now and then is essentially a progress update on whether that forecast is realistic or aspirational. September 2 is the next exam.
