Wall Street’s favorite bet falters as chip stocks whipsaw the market

For most of 2026, betting on chip stocks felt less like investing and more like printing money. The Philadelphia Semiconductor Index, known as the SOX, had gained over 100% in the first half of the year alone, powered almost entirely by the market’s collective conviction that AI would need silicon in quantities the world had never seen before. Then came the unraveling.

By July, semiconductor stocks had slipped into bear market territory, with the SOX logging single-session declines of roughly 5 to 6%. The AI trade, once the most celebrated position on Wall Street, started to look a lot like a crowded elevator with a snapped cable.

How a $1.3 trillion wipeout happens

The damage started accumulating in early June, when the sector shed approximately $1.3 trillion in combined market value over a short stretch of sessions. To put that in perspective, that is roughly the GDP of Spain, gone from a single corner of the equity market in a matter of weeks.

Nvidia, the face of the AI chip boom, retreated around 2.5% during the sell-off. Broadcom’s situation was more acute, with the company facing significant guidance challenges that spooked investors who had priced in nothing short of perfection. Memory chip makers like Micron and SK Hynix also took hits, erasing gains that had built up over months of AI-adjacent enthusiasm.

The catalyst was not one single headline but a convergence: anxiety over whether AI capital expenditure could sustain the pace markets had assumed, rising interest rate concerns, and geopolitical tensions that have become a permanent background hum for global tech supply chains.

A Bank of America survey of fund managers conducted in July found that 82% of respondents identified semiconductors as the single most crowded trade in the market.

The irony of the first-half scoreboard

The rotation hitting chip stocks looks especially striking when you compare what different asset classes actually delivered in the first half of 2026. The SOX returned roughly 102% over that period. Bitcoin, by contrast, fell 33% over the same stretch.

But the semiconductor sell-off changed the arithmetic. As the AI trade unwound and fund managers started rotating toward more stable sectors like transportation, Bitcoin quietly held above $64,000 through July’s turbulence.

Semiconductor stocks outperforming Bitcoin by 135 percentage points in six months created a significant relative value gap.

What this means for investors watching both sides

The same survey that put 82% of fund managers in the crowded trade camp also implies that a coordinated exit could produce more volatility than even July’s sharp sessions suggested.

The guidance challenges at Broadcom deserve particular attention. When a company at the infrastructure heart of the AI buildout signals uncertainty about forward demand, it raises questions that extend well beyond one firm’s earnings call. It forces the market to revisit assumptions about data center spending timelines and the rate at which AI deployment translates into actual chip orders.

For crypto investors, the read is more nuanced. Bitcoin holding above $64,000 during a period when Wall Street’s most beloved trade was unraveling is a data point, not a thesis. It suggests some degree of decorrelation from the AI equity complex, which is meaningful given how tightly crypto had tracked risk assets in prior cycles.
