Broadcom AI Chip Revenue Jumps 221% But Q4 Guidance Falls Short

What happened

Broadcom's fiscal third-quarter earnings, released September 2, delivered one of the more startling numbers of this AI cycle: AI semiconductor revenue of $16.7 billion, up 221% from a year earlier and 54% sequentially 789. Total revenue reached $29.6 billion, an 86% year-over-year increase, while non-GAAP diluted earnings per share climbed 96% to $3.32 and GAAP diluted EPS jumped 215% to $2.68 710. Free cash flow hit $13.7 billion, equal to roughly 46% of revenue, and operating income rose 92% on a non-GAAP basis to $20.1 billion 79. AI-related chips now make up about 56% of Broadcom's total sales, up from 49% the prior quarter 8912.

Both revenue and adjusted earnings beat Wall Street's consensus, though outlets differ slightly on the size of that beat depending on which estimate set they cite. Investing.com pegged consensus at $29.25 billion in revenue and $3.21 in adjusted EPS, implying a beat of about 1.2% on revenue and 3.4% on earnings 8. The Motley Fool cited a slightly different consensus of $29.4 billion and $3.24 adjusted EPS, still a clear but unspectacular beat 10. Either way, the takeaway is the same: Broadcom didn't just grow — it grew faster than analysts already-elevated models expected, even if not by a wide margin.

Despite that, shares barely moved, and multiple outlets frame the muted reaction as the real story of the quarter 101113. The culprit was guidance. Broadcom forecast fourth-quarter revenue of approximately $34.8 billion, up 93% year-over-year, but that came in just below the analyst average of roughly $35 billion to $35.03 billion cited by Yahoo Finance and Benzinga using LSEG data 111413. Truist Securities cut its price target from $550 to $520 while keeping a Buy rating, calling the results and outlook "good, but not stellar or completely clean" 11. Meanwhile Cantor Fitzgerald, BMO Capital and Rosenblatt all raised their price targets — to $600, $575 and $600 respectively — while maintaining bullish ratings 14.

The scale of the AI ramp

Broadcom's custom accelerator, or XPU, shipments rose more than 3.5 times year-over-year and made up 73% of AI revenue in the quarter, while AI networking revenue grew more than 2.5 times 89. CEO Hock Tan pointed to six major XPU customers driving the surge, and multiple sources name Google, Anthropic, OpenAI and Meta as key partners, with Google's Tensor Processing Units historically the largest piece of that business 913. During the quarter, Broadcom shipped Ironwood TPU v7 to both Google and Anthropic, and delivered Jalapeno, described as OpenAI's first custom accelerator 89.

Management's guidance extends well beyond the current quarter. Broadcom raised its fiscal 2026 AI semiconductor revenue outlook to $58 billion, up from a prior $56 billion forecast, and projected fourth-quarter AI revenue of $21.7 billion, up 236% year-over-year 7916. Looking further out, Tan laid out targets of roughly $115 billion in AI semiconductor revenue for fiscal 2027 and $230 billion for fiscal 2028, alongside a first-ever long-range projection of more than $30 in non-GAAP earnings per share by fiscal 2028 8912. Tan said the company has "secured the supply" to meet those targets even as demand continues to run ahead of them 89.

Those multiyear numbers matter because they reframe Broadcom's AI story from a quarterly beat into a stated multiyear trajectory, something analyst commentary compares to Nvidia CEO Jensen Huang's practice of guiding markets years in advance 12. Whether that guidance functions as a floor or a stretch target is likely to shape how the stock trades well into 2027 and 2028.

Margins under pressure

Gross margin came in at 75% for the quarter, better than Broadcom's own 74% guidance but down 210 basis points sequentially 89. Management expects fourth-quarter gross margin to fall further, to roughly 73%, as AI accelerators carry heavier memory content that dilutes margins even as revenue grows 912. Despite that, operating margin is expected to hold near 66%, roughly flat year-over-year, because revenue growth is generating enough operating leverage to offset the gross-margin drag 79.

The $1,000 question

Several outlets ran the now-standard "if you'd invested" exercise, and the figures vary considerably depending on the starting date. One calculation found that $1,000 put into Broadcom on September 8, 2025 would be worth about $1,070 including dividends a year later — a modest 7% gain that looks unremarkable next to the operating numbers 118. A separate stock-return tool using a July 9, 2025 start date put the one-year value at $1,399 19. A Motley Fool piece from November 2025 calculated that a one-year hold ending that month would have grown $1,000 to roughly $2,066, as the stock had more than doubled over the prior twelve months 20. Longer-horizon figures diverge just as much: one calculation found $1,000 invested a decade ago, in August 2016, would have grown to $25,041 excluding dividends 17, while another dated the ten-year mark to July 2016 and arrived at $24,701 including dividends, a 37.8% compound annual growth rate 19.

Where the reporting agrees

Across all the outlets covering this earnings report, the core financial facts are consistent: $29.6 billion in quarterly revenue, 86% year-over-year growth, $16.7 billion in AI semiconductor revenue up 221%, and adjusted EPS of $3.32 7891015. There's also broad agreement on why the stock didn't rally despite those numbers — Broadcom's $34.8 billion fourth-quarter revenue guidance landed just under Wall Street's roughly $35 billion consensus, and in a market pricing Broadcom for flawless execution, even a small guidance miss was enough to trigger profit-taking 10111314. Every outlet that addresses analyst sentiment describes it as still fundamentally bullish, with price-target increases from several major firms outnumbering the one notable cut from Truist 141516.

Where it doesn't

The clearest divergence is in the $1,000-investment framing, and it isn't really a disagreement so much as a function of differing time windows. Depending on whether the calculation starts in July 2025, September 2025, or November 2024, and whether dividends are included, the one-year return ranges from roughly 7% to 40%, or even to a full doubling in the case of the November 2025 Motley Fool figure 1181920. None of these outlets are wrong; they're simply measuring different twelve-month windows against a stock that has been unusually volatile, including a reported pullback of around 26% from its June peak noted by Blockonomi 16.

There's also some looseness around consensus estimates themselves. Investing.com's cited consensus of $29.25 billion in revenue and $3.21 adjusted EPS differs slightly from the $29.4 billion and $3.24 figures used elsewhere 810, and the gap between Broadcom's $34.8 billion guide and Wall Street's expectation is variously described as 0.7% or roughly $230 million short, depending on whether the source cites $35 billion or the more precise $35.03 billion LSEG figure 111214. These are rounding differences rather than substantive contradictions, but they do produce a wide range of price targets: Yahoo Finance-sourced compilations put the analyst average as low as $521.41 and as high as $530.32, with individual targets spanning $400 to $630 1516.

On the substance, the evidence points clearly in one direction: this was an exceptional operating quarter that ran into a market unwilling to reward anything short of a blowout guide. The revenue and AI-growth figures are not in dispute anywhere in the coverage, and the muted stock reaction is best explained not by weakness in Broadcom's business but by how aggressively the market had already priced in AI-fueled outperformance. The bull case built on $115 billion and $230 billion in future AI revenue remains unproven guidance rather than delivered results, and that gap between forward promise and near-term stock performance is the tension every outlet, in its own way, is describing.

Why it matters

Broadcom's results reinforce that the AI infrastructure buildout extends well beyond Nvidia's GPU dominance. Custom accelerators and networking gear tied to a handful of hyperscale customers — Google, Anthropic, OpenAI and Meta among them — are now generating tens of billions in quarterly revenue, and Broadcom's own long-range targets imply that business could nearly quadruple by fiscal 2028 91213. For investors and the broader market, the report sets up a new bar: strong absolute growth is no longer sufficient on its own, and future quarters will be judged against whether Broadcom can keep converting demand into upside surprises rather than merely meeting an increasingly aggressive set of expectations.
