Broadcom’s market capitalisation has fallen by more than $440 billion in a matter of days, reviving broader concerns that artificial intelligence chip stocks are overvalued.

On June 9, IT outlet TechRadar reported that Broadcom posted record revenue in fiscal 2026 second quarter and tripled AI chip business revenue from a year earlier. Its shares then saw a sharp correction after it failed to meet market expectations for its growth path.

Broadcom’s enterprise value slipped to about $1.88 trillion recently from about $2.28 trillion on June 2. It is still up 14.09 percent so far this year, but the short-term drop was enough to unsettle markets. Investors wanted a more specific explanation of how it would sustain growth in the second half of this year, rather than focusing on the results themselves.

The correction did not stop with Broadcom. Stocks with a large weighting in AI and semiconductors faced selling pressure, and Nvidia fell about 6 percent. Nvidia is maintaining a market value of about $5.05 trillion, but the Broadcom plunge again highlighted valuation burdens across the sector and shook investor sentiment.

The market still expects demand for Nvidia’s AI chips to continue and its technological edge over rivals to hold. But investors are shifting their focus from a simple race in chip performance to per-token efficiency and power issues. As AI data centre investment expands, efficiency as well as performance is emerging as a key evaluation standard.

It has already become clear that Nvidia is not immune to sharp corrections. When Chinese researchers released DeepSeek and a narrative spread that distillation models could cut demand for graphics processing units to a fraction of earlier expectations, Nvidia shares plunged 17 to 18 percent in a single day. About $600 billion in market value was wiped out at the time. Nvidia later said it rated DeepSeek highly for originality, but said the importance of its chips would remain or grow further.

The Broadcom case also highlighted a gap between forecasts offered by AI companies and market expectations. Investors are demanding stronger future guidance than companies can reasonably provide, and even strong results are failing to defend share prices. Some experts pointed to market demands growing beyond what AI companies can promise.

Against this backdrop, the market is also watching the possibility of large initial public offerings by Anthropic and OpenAI. As both are discussed at valuations below $1 trillion, the broader AI sector’s valuations could become more sensitive. As investors chase the next big winner, capital is moving faster and even small gaps between expectations and results are increasingly driving share-price volatility.

In the same context, there was also analysis that the recent drop in cryptocurrency market capitalisation coincided with money moving to participate in a SpaceX IPO. It was cited as a case showing that investor funds can shift to other growth narratives even though SpaceX recently played down its AI ambitions.

The next watershed is Nvidia’s earnings report. Nvidia will release fiscal 2027 second-quarter results on Aug. 26. The market is watching whether demand for AI chips will continue or whether the current frenzy will cool. With some investors including Bridgewater Associates’ Ray Dalio (레이 달리오) warning that a huge bubble has formed in the stock market, Nvidia’s results are expected to help gauge whether the correction in AI chip stocks is a temporary shakeout or the start of a structural revaluation.
