Broadcom's $300 Billion Wipeout Exposes a New Divide in the AI Chip Trade

Broadcom lost up to $319B in market cap after record revenue and 48% sales growth failed to meet lofty AI guidance expectations. Most Wall Street analysts remain bullish, but Macquarie warns of Google concentration risk.

A single trading session erased between $280 billion and $319 billion from Broadcom's market capitalization on Thursday — one of the largest one-day value destructions ever recorded for a US megacap stock. The trigger wasn't bad news. Broadcom posted record quarterly revenue of $22.19 billion, a 48% surge, and adjusted earnings per share of $2.44 that beat the $2.40 consensus. But the market had already priced in perfection, and the company's AI chip guidance fell a crucial mile short.

The sell-off deepened into Friday, with shares closing at €338.60, down 6.26% on the day and 11.77% for the week. At that level, the stock sits 21.18% below its 52-week high of €429.60 reached on June 3. On a year-to-date basis, however, Broadcom still holds a gain of roughly 14%.

AI Engine Roars, Guidance Stumbles

Broadcom's AI semiconductor business delivered $10.8 billion in revenue during the fiscal second quarter — a 143% jump year-over-year and now nearly half of total company sales. CEO Hock Tan painted an even more explosive picture for the third quarter, forecasting AI chip revenue of $16 billion, representing more than 200% growth from a year earlier.

That should have been a knockout punch. Instead, the number came in roughly $1.2 billion below what analysts had modeled, with some street estimates reaching as high as $17.2 billion. Tan also reaffirmed, but did not raise, the cumulative AI revenue target of $100 billion-plus by fiscal 2027. For a stock trading on stretched multiples, a "confirm and hold" message was enough to trigger a rout.

Macquarie Draws a Line in the Sand

While most Wall Street banks rushed to call the dip a buying opportunity, Macquarie broke ranks. The investment bank downgraded Broadcom from Outperform to Neutral and slashed its price target by 15% to $437.

The core concern revolves around customer concentration, specifically Google. Macquarie estimates that Broadcom's share of Google's TPU-related revenue will slide from roughly 95% in 2026 to 80% in 2027 and then to 65% in 2028, as Google develops its own chip capabilities and works with MediaTek. Despite raising earnings estimates for 2026 and 2027 by 12% and 14% respectively, Macquarie cut its 2028 profit forecast by 21%.

Bullish Consensus Holds

Macquarie's downgrade remains an outlier. Within 24 hours of the stock's collapse, a parade of heavyweight firms lifted their price targets: Jefferies to $550, JPMorgan to $580, Mizuho to $530, Deutsche Bank to $515, Goldman Sachs to $525, and Morgan Stanley to $502. Of 47 analysts tracked by S&P Global, the consensus rating is Strong Buy with an average target of $511.

The prevailing Wall Street view is that the sell-off reflects a "catalyst gap" — a temporary vacuum between quarters — rather than a deterioration in AI demand. History offers some comfort: after previous Broadcom declines of 6% or more, the median return was 8% after one month, 20% after three months, and 35% after six months.

Strategic Pivot and New Client Ties

Amid the noise, Broadcom is sharpening its business model. The company will now sell only custom-designed AI chips, abandoning full-system sales. Tan confirmed six core customers for these custom ASICs: Anthropic, Google, Meta, and OpenAI, with shipments to OpenAI already underway.

The software segment, however, showed some cracks. Infrastructure software revenue came in at $7.18 billion versus the $7.32 billion expected, a rare miss in a division that had been a steady growth contributor.

Sector Shock Waves

The Broadcom sell-off cascaded across the semiconductor landscape. AMD lost 10%, Micron dropped 11%, and Intel fell 9%. Nvidia also came under pressure. The Nasdaq Composite declined 3% as capital rotated into defensive sectors, pushing the Dow to a fresh record. For the chip sector, the message was clear: even the fastest-growing AI names are no longer immune to the discipline of expectations.

Dividend a Distant Concern

Broadcom's quarterly dividend of $0.65 per share, payable June 30 with an ex-dividend date of June 22, extends a 15-year streak of increases. In the current environment, however, the payout is unlikely to provide much support. Investors are laser-focused on whether the ASIC strategy will continue to be perceived as a competitive moat — or as a dependency risk.

The next clear inflection point comes with the fiscal third-quarter results, when Broadcom will have to demonstrate that its growth trajectory can outrun the rising tide of customer in-sourcing and the gravitational pull of ever-higher market expectations.
