Broadcom Q3 Earnings Test a $16B AI Revenue Guidance

The Number to Watch Is $16 Billion

Broadcom reports fiscal third-quarter results after the close on Wednesday, September 2, 2026. The company set its own bar back in June, and it is a high one: $29.4 billion in consolidated revenue, up 84% year over year, with non-GAAP operating margin around 67%.

Inside that, the figure that will move the stock is AI semiconductor revenue. Broadcom guided to $16.0 billion for the quarter — growth of more than 200% year over year, and more than half of total expected revenue.

• Q3 revenue guidance of $29.4 billion, an 84% year-over-year increase, issued with Q2 results on June 3, 2026
• AI semiconductor revenue guided to $16.0 billion, up over 200% year over year
• Q2 actuals for comparison — $22.2 billion total revenue, up 48%, with AI semiconductor sales of $10.8 billion, up 143%
• Q2 AI bookings exceeded $30 billion against $10.8 billion shipped, a backlog that stretches visibility well past this fiscal year

Why the Backlog Matters More Than the Print

Here is the thing about a company guiding to 84% growth: the quarter itself is close to decided by the time it is announced. Custom silicon does not get bought on impulse. These are multi-quarter design wins with committed volumes, which is exactly why Q2's $30 billion in AI bookings against $10.8 billion shipped is the more informative number.

That gap is the story. A backlog roughly three times the quarter's shipments means the constraint is supply and schedule, not demand. Management raised full-year AI revenue guidance to $56 billion at the last print and reiterated a target above $100 billion for fiscal 2027 — figures that only make sense against an order book of that shape.

What I will actually be reading for on Wednesday is whether the backlog grew again. Revenue tells you about last quarter. Bookings tell you about the next four.

What Does This Mean for the Broader AI Trade?

Broadcom sits at a specific spot in the AI supply chain that makes its results a useful cross-check. It builds custom accelerators for hyperscalers rather than selling merchant GPUs, which means its numbers read as a direct measure of how much of the industry is designing its own silicon instead of buying off the shelf.

That is a different signal from Nvidia's, and the two are not substitutes. Nvidia's Q2 revenue doubled to $96.2 billion with guidance to $108 billion, and Broadcom's custom-silicon growth is running alongside it rather than against it. Both being up sharply is the more interesting outcome, because it suggests the compute buildout is broad rather than concentrated in one vendor's order book.

Broadcom's most visible custom project remains the OpenAI Jalapeño inference chip, which has since produced first benchmark results showing 1.9x work per kilowatt. Any commentary on how that programme scales would be the most valuable thing said on the call.

A Note on Expectations

None of this is a prediction, and it is certainly not advice. Wall Street consensus sits close to the company's own guide — around $29.4 billion in revenue — which means the setup is one where meeting guidance is the baseline rather than the win. Stocks that have run into a print on a strong sector tape can react to guidance rather than results, and Broadcom's last report was a reminder that a good quarter and a good reaction are separate events.

Full-year context helps: Broadcom's Q1 FY2026 report showed AI revenue doubling to $8.4 billion. Getting from there to a guided $16 billion in two quarters is the trajectory the market is pricing.
