Broadcom is designing custom AI chips for Google, Meta, OpenAI, and Anthropic. Its AI semiconductor revenue just grew 221% in a single quarter. The stock is trading about 30% below its 52-week high. Those three facts, sitting together, describe an unusual situation.

Why This Stock Now

On September 2, Broadcom reported fiscal Q3 2026 results that were records across every financial line. Revenue reached $29.6 billion, up 86% from a year earlier. AI semiconductor revenue specifically hit $16.7 billion, up 221% year over year, and represented 56% of the company’s total revenue for the quarter. Free cash flow was a record $13.665 billion, equal to 46% of revenue. Net income more than tripled to $13.088 billion.

The stock dropped on the report. The stated reason was that Q4 revenue guidance of $34.8 billion landed slightly below what some analysts had penciled in. The actual guidance implies 93% year-over-year growth. The market chose to focus on the delta versus the most optimistic estimates rather than the underlying trajectory.

That reaction — punishing a record quarter because guidance missed the most bullish forecasts — is worth examining in detail. Broadcom’s Q3 earnings breakdown: 221% AI revenue growth and a $230 billion roadmap walks through exactly what the numbers say versus what the market priced in, and why the gap between the two may be the setup traders are watching.

The Business

Broadcom occupies a specific and defensible position in AI infrastructure: it designs custom accelerator chips, often called XPUs, for hyperscalers and AI labs that want alternatives to Nvidia’s general-purpose GPUs. Each customer gets silicon engineered around their specific workload, which can mean better performance per dollar than off-the-shelf solutions. That specificity also creates multi-year dependency, since switching requires rebuilding the software stack.

During Q3, Broadcom said it shipped Google’s TPU v7 “Ironwood” in high volume and began production shipments of Google’s next-generation TPU v8i. Broadcom and OpenAI also publicly unveiled Jalapeño, OpenAI’s first custom intelligence processor, as part of a multi-generation program the two companies are building together. Apple has also discussed increasing U.S. investment tied to domestic chip production, but Broadcom has not specifically attributed that plan to increased Apple spending with Broadcom in its Q3 release.

The Apple relationship has been a recurring thread in Broadcom’s story for longer than the current AI cycle. Broadcom’s Apple chip deal and what it meant for the stock’s recovery from a 19% drawdown covered how that partnership was framed when the stock was at an earlier low, providing a reference point for how the market has historically treated Apple-linked revenue expectations.

Why Wall Street Is Paying Attention

Management said it expects fiscal 2026 AI revenue to be $58 billion, up 186% from the prior year. Beyond that, CEO Hock Tan outlined targets of about $115 billion in AI semiconductor revenue in fiscal 2027 and $230 billion in fiscal 2028, which he framed as a “line of sight” rather than a formal guide. The company has discussed ambitions for materially higher earnings power by fiscal 2028, but specific figures for 2028 EPS, the 2028 consensus EPS, the number of analysts with a Strong Buy rating, and an average price target can change day to day and are not provided in Broadcom’s earnings materials, so they should be treated as directional rather than definitive.

The multi-year backlog reached $179.2 billion at the end of Q3, up more than 550% year over year. That figure covers contracted work not yet converted to revenue, across the existing customer set.

The scale of that backlog figure becomes clearer when set against where Broadcom’s roadmap stood just a few months earlier. Broadcom’s $100 billion AI roadmap: what the backlog and revenue numbers actually say examined the earlier version of these targets alongside the $30 billion-plus backlog at that time, offering useful context for how quickly the contracted pipeline has expanded since.

What’s Driving the Opportunity

The pullback from $495 to around $340 reflects two things: profit-taking after a massive run, and concern that AI infrastructure spending will slow before Broadcom’s FY2027 and FY2028 targets materialize. Both are reasonable concerns. What they miss is the contractual nature of the backlog. Broadcom is not guessing at future demand; it is executing against signed multi-year agreements with some of the most capital-intensive buyers in the world.

Q4 guidance calls for AI semiconductor revenue of $21.7 billion, up 236% from a year earlier. Non-GAAP operating margins are guided at 66%, with gross margins around 73%. The cash generation, $13.665 billion in free cash flow last quarter, easily funds the roughly $3.1 billion quarterly dividend and ongoing debt reduction.

What Could Go Wrong

Customer concentration is the clearest risk. Management has said that six customers drive its AI revenue, and four of those customers were named publicly: Google, Meta, OpenAI, and Anthropic. If those buyers slow their infrastructure build, Broadcom’s revenue trajectory moves with it. The company has also described residual value guarantees as part of its broader guarantee arrangements, which can create contingent liabilities. EU antitrust regulators are also scrutinizing Broadcom’s VMware licensing changes, which adds an overhang on the software segment.

The Bottom Line

Broadcom just delivered a record quarter on a free cash flow basis, raised full-year AI expectations, and laid out a two-year roadmap that management argues is supported by contracted backlog rather than projection. The stock is about 30% below its 52-week high. At around $340 with $58 billion in AI revenue expected for this fiscal year, the gap between what the business is doing and where the stock is trading looks like a re-entry the company’s numbers support.
