Broadcom’s AI Business Is Soaring. So Why Is the Stock Crashing?

Broadcom's AI division is on fire—revenue surging, demand exploding. Yet, the stock chart looks like a cliff dive. What gives?

The AI Engine Roars

Forget the noise. The core story is simple: Broadcom's custom AI chip business is a runaway train. Enterprise clients are scrambling for their solutions, weaving them into next-gen data centers. The numbers don't lie—this segment is posting growth that makes the rest of the semiconductor sector look sleepy.

The Market's Myopia

So why the disconnect? The street has a nasty habit of punishing complexity. While the AI unit shines, legacy segments face cyclical headwinds. Investors, in their infinite wisdom, often dump the whole basket when one apple shows a bruise—a classic case of short-term panic overriding long-term vision. It's the finance equivalent of selling your Ferrari because the ashtray is full.

The Bottom Line

This isn't a story of fundamental failure. It's a narrative clash. One division's explosive potential is being drowned out by broader, noisier concerns. For those with a stomach for volatility, it presents a glaring paradox: a leading player in the era's defining tech trend, trading on fear, not facts. The machines are learning; the market, it seems, still has a way to go.

Key Takeaways

• Shares of chip designer Broadcom tumbled on Friday as Wall Street focused in on margin pressure from its fast-growing AI business.
• Investors have scrutinized tech earnings more intensively in recent months amid concerns Silicon Valley is overspending on AI.

Broadcom’s custom AI chip business is growing rapidly. Wall Street, however, is wary about how much upside that growth suggests.

Broadcom (AVGO) on Thursday predicted its AI-related revenue will double year-over-year to $8.2 billion in the current quarter. That WOULD be an acceleration from the most recent quarter, when it grew 74% to $6.5 billion. But the forecast came with a caveat—and that weighed on the shares today. The stock was recently down about 10% in intraday trading.

Broadcom expects its gross margin to contract 100 basis points, or 1 percentage point, quarter-over-quarter, “primarily reflecting a higher mix of AI revenue,” said chief financial officer Kirsten Spears on a call with analysts Thursday night. 

Key Takeaways

Optimism about artificial intelligence has propelled tech stocks and the broader market to record highs this year. But mounting concerns about an AI bubble have made investors more cautious in recent months, pressuring shares of AI darlings in the process.

The notion that higher AI sales might be a drag on profitability wasn't what investors wanted to hear. But investors have lately upped their scrutiny of tech earnings due to concerns about stretched stock valuations and unsustainable infrastructure spending, meaning that even good news is getting put under a microscope.

That's led to less-than-rollicking market responses to corporate results. Nvidia (NVDA), the leading supplier of AI chips and Broadcom’s largest competitor, blew past estimates with its numbers last month, but its stock slumped under the weight of AI bubble concerns. Software giant Oracle (ORCL) on Wednesday said its backlog now exceeds $500 billion, but it failed to convince investors that its huge AI investments will pay off soon. Its stock slumped yesterday to lead an AI sell-off.  

Broadcom, meanwhile, isn't the only tech company whose profitability is being pressured by AI. In October, Oracle forecast its AI cloud infrastructure business would achieve gross margins between 30% and 40%, roughly half that of its legacy software business.

This year’s AI-driven rally has also set a high bar for tech earnings. Heading into Thursday’s results, Broadcom shares were up 75% since the start of the year. The stock ROSE about 20% in the past month alone thanks to Google’s newest AI model, which was trained on Broadcom-designed chips and lauded as a serious challenger to OpenAI’s ChatGPT. 

Bank of America analysts in a note Friday called Wall Street’s worries about profitability a “fair concern.” They lowered their 2026 and 2027 margin estimates by a couple percentage points. Nevertheless, they raised their earnings estimates for those same years, reflecting their belief that faster revenue growth will more than offset narrowing margins. Deutsche Bank analysts made the same adjustments, and raised their share price target.
