Broadcom Stock Surged for Years. Now Investors Are Asking a Harder Question.

Wall Street screens flicker with the same ticker, AVGO, late on a trading afternoon. Similar to how traders used to watch Intel or Cisco decades ago, broadcom stock is now one of those symbols that they watch almost automatically. But this time, the topic of discussion is artificial intelligence, a field that appears to be growing more quickly than analysts can forecast.

There’s a feeling that Broadcom came quietly to this point. In late 2024, the company’s market value surpassed $1 trillion, making it a member of a select group dominated by the typical tech titans. However, the route there didn’t appear to be glamorous. Acquisitions, obscure chip components, and the kind of enterprise software that quietly manages corporate infrastructure but seldom makes headlines were used to build it.

When you stroll through the company’s Palo Alto headquarters, it feels more like a disciplined industrial machine than a flashy Silicon Valley startup. Engineers discuss networking switches and ASIC chips with the composure of those who understand how important they are to hyperscale data centers. Investors are pushing Broadcom stock into portfolios centered around the AI boom, suggesting that they are also aware of this confidence.

The numbers themselves provide an intriguing narrative. AI revenue recently reached about $8.4 billion in a single quarter, doubling year over year. Custom AI chips—those specialized processors made for businesses using large models—jumped even more quickly. As this develops, it’s difficult to ignore how different Broadcom’s role is from that of businesses like Nvidia. The eye-catching graphics processors are sold by Nvidia. The invisible plumbing that enables those processors to communicate with one another is sold by Broadcom. All of a sudden, that plumbing is extremely valuable.

Cables stretch across rows like industrial vines, and racks of servers hum behind metal cages inside data centers in places like Northern Virginia or Phoenix. Switching hardware and networking chips maintain system synchronization. Though few people outside the industry are familiar with the name, Broadcom is the source of many of those components. But more and more investors do.

However, the movement of Broadcom’s stock hasn’t been exactly linear. Despite strong earnings, the shares have declined by almost 20% in the last few months. Sometimes caution is indicated by that kind of pause. Even if a company’s fundamentals appear solid, markets may become uneasy when it becomes overly dependent on a single theme, in this case artificial intelligence.

It’s possible that investors are just adjusting their expectations. After all, the stock of Broadcom has already produced exceptional long-term returns. The company produced one of the highest total shareholder returns in the semiconductor industry over the past ten years. These profits came from a strategy that occasionally baffled outsiders in addition to chip sales.

An excellent example is the acquisition of VMware. Critics questioned why a chipmaker would want a virtualization software company when Broadcom announced the $69 billion deal in 2022. The reasoning now makes more sense. Compared to hardware, software has much larger profit margins, and once systems are embedded, enterprise clients typically stick around for years. Now, Broadcom’s revenue mix, which is roughly 58% semiconductor and 42% software, appears to be a purposeful hedge against the chip cycle’s volatility.

Uncertainty persists, though. The AI division of Broadcom is largely dependent on a small number of very large clients. If technology trends change, cloud giants ordering custom chips have the potential to drastically alter spending. Even as they celebrate the growth, investors appear to be aware of the concentration risk.

The issue of scale is another. By 2027, Broadcom thinks its AI chip clients could bring in over $100 billion. Even in a time when AI budgets seem boundless, that prediction seems almost unreal. The prediction might turn out to be correct. However, forecasts of that magnitude often cause seasoned investors to feel a little uneasy.

There are moments when watching the stock market’s response to Broadcom is like watching a slow-motion acknowledgement of something that is already taking place in the background. For years, the networks, switches, and specialized chips that make up the AI infrastructure have been quietly developing. Broadcom just so happens to be situated at a number of important intersections.

And that brings up a subtle question that keeps coming up in discussions with analysts: has the market finally caught up with the story, or is Broadcom stock still cheap?

According to some models, if the demand for AI continues to grow, the shares may still trade higher. Some contend that the optimism already presupposes years of flawless performance. Both points of view seem reasonable.

The scope of the AI build-out becomes more apparent when one stands outside a hyperscale data center, where delivery trucks unload server racks late into the night. The machines within execute algorithms, train models, and provide answers to queries. However, everything is connected by a dense network of chips. Many of those chips are sold by Broadcom. Investors have recently begun to take notice.
