Broadcom's AI success story gets complicated ahead of earnings
Broadcom (AVGO) reports fiscal Q3 2026 results after the close on September 2, and investors want proof its AI boom can justify a valuation that has shed roughly $520 billion in market value since June. After Nvidia's blowout quarter set a high bar, Wall Street is watching whether CEO Hock Tan can deliver a reset—not just meet numbers already on the table.
Key Takeaways
- AVGO shares have fallen about 30% from their June peak after AI revenue guidance disappointed, erasing roughly $520 billion in market cap.
- Management guided Q3 AI semiconductor revenue to $16 billion—up 200% year over year—but that figure trailed the $17.2 billion analysts expected in June.
- Barron's puts consensus at $29.2 billion in Q3 sales and $3.22 adjusted EPS; the real test is whether Tan raises forward AI targets.
- AVGO is up only about 6.7% in 2026, lagging the PHLX Semiconductor Index's roughly 60% gain despite explosive AI chip growth.

Why Has Broadcom Lost $520 Billion in Market Value?
According to Bloomberg, Broadcom's summer slide began after its June outlook landed below investor expectations. Shares tumbled when Tan guided fiscal Q3 AI semiconductor revenue to $16 billion—well short of the $17.2 billion analysts had penciled in.
Barron's notes the stock has dropped roughly 30% from its June peak. For a company positioned as the third-most valuable chipmaker, that is a sharp repricing of an AI narrative that once looked unstoppable.
What Numbers Will Wall Street Watch Tonight?
Most headline figures are already known. In June, Broadcom guided total Q3 revenue near $29.4 billion, up 84% year over year, with AI chips driving more than half of sales. Barron's reports analysts expect about $29.2 billion in revenue and adjusted earnings of $3.22 per share.
The print itself may matter less than the forward view. Tan has reiterated a fiscal 2027 AI semiconductor target above $100 billion without raising it—a pattern that frustrated markets last quarter. Investors now want an updated AI figure and evidence that order conversion is accelerating, not stalling.
Can Broadcom Match Nvidia's Earnings Momentum?
Nvidia raised the stakes last week, projecting roughly 70% sales growth in its next fiscal year and sending its stock to its best day since April 2025. Bloomberg frames Broadcom's task as delivering a similarly confidence-building report to halt the skid.
Yet AVGO's setup looks harder. The stock is up only about 6.7% year to date while the PHLX Semiconductor Index has climbed near 60%, per Barron's. Even when Broadcom beats estimates, shares have often sold off on guidance—making tonight's call as much about tone as totals.
What Makes Broadcom's AI Story Complicated?
On paper, the growth is extraordinary: Q1 AI revenue hit $8.4 billion, Q2 reached $10.8 billion, and Q3 is guided to $16 billion. Full-year AI sales are targeted at $56 billion. The complication is that markets already priced that ramp—and punished Tan when he did not exceed it.
As the Wall Street Journal flagged, Broadcom's AI success story is getting harder to sell. Custom-chip customers like Google and OpenAI remain partners, but investors are weighing concentration risk, margin mix shifts, and whether giant AI financing structures can sustain demand. Tonight's earnings will show whether AVGO can simplify that story—or deepen the doubt.
