AI Infrastructure Rotation Beyond NVDA in 2026

It is not hyperbole to say that NVIDIA Corp. NASDAQ: NVDA it has made many investors millionaires.

NVDA is up more than 1,300% over the past five years. Go back 10 years, and NVDA delivered an impressive total return of more than 23,800%. That means an investor who put about $3,500 into NVIDIA stock 10 years ago and thought he would be a millionaire.

Indeed, the problem is that many investors have not seen NVIDIA’s important role in the evolution of artificial intelligence (AI). It was a revolutionary event that continues to move the economy.

But it also changes the perception of where the smart money is going. To be sure, NVDA will continue to perform well. But it “only” increased by about 11% in 2026, and before mid-April, it was a bad year.

The AI ​​Infrastructure Story Is Growing

The bearish view on NVIDIA is that the AI ​​bubble is ready to burst. This earnings season clearly doesn’t support that, but the narrative won’t die easily.

A more accurate reason for the slide in NVDA is rotation within the AI ​​context. Specifically, investors have realized that NVIDIA is not the only game in town.

The market has grown by treating AI as a full-stack architecture—computing, power, cooling, networking, and software—rather than a single company business, and there are other key AI architecture companies that are part of the “NVIDIA and” portfolio.

These stocks are entering a pickings and shovels theme that is growing stronger. Although they reside in different parts of the AI ​​infrastructure chain, each is tied to the physical and technical requirements of scaling AI. And the commonality of the group is their strong growth since April 1, which is likely to continue for several years.

Vertiv Solves the AI ​​Data Center Cooling Problem

Data centers require large amounts of energy and emit large amounts of heat. That requires thermal management solutions, hence Vertiv NYSE: VRT increased by more than 100% by 2026, and increased by almost 260% last year.

A company is like a person selling umbrellas on a rainy day. Hyperscalers have a problem; Vertiv has solutions.

Vertiv reported Q1 2026 earnings on April 22. The only factor in the otherwise strong report was a possible headwind from costs. Since the earnings release, some analysts have been raising their price targets, but the updated targets are generally in line with VRT’s current price. One could argue that this shows that new investors should wait for a better entry point.

On the other hand, analysts are predicting 33% revenue growth, which makes the company’s forward price-earnings (P/E) ratio of nearly 50x seem like a premium to pay.

Another concern is that Amazon.com Inc. NASDAQ: AMZNa current Vertiv customer, is developing its own liquid cooling solution. This may be a long-term windfall, but it only affects 10% of the company’s revenue.

Cadence Design Systems Powers the Next Generation of AI Chips

Chipmakers are getting a second wind in the AI ​​trade. That explains why shares of Cadence Design Systems NASDAQ: CDNS are up nearly 27% over the past month. And it’s a good bet that the stock will still work.

Cadence provides electronic design automation (EDA) software, hardware and intellectual property needed by chipmakers, especially companies that make more advanced chips.

The company reported its Q1 2026 earnings on April 27 with some top and bottom hits. Recent acquisitions may depress earnings for the remainder of this calendar year. But the long-term outlook for CDNS looks strong and is supported by analysts raising price targets since the earnings report. KeyCorp has a higher price target of $425, up from $405.

That said, Cadence has a forward P/E of about 57. That could be seen as a strong valuation if the company’s earnings are impacted in future quarters.

Ciena Builds High-Speed ​​AI Connectivity Core

Ciena Corp. NYSE: CIEN is an optical carrier, specializing in the high-speed optical connections required by data centers.

It’s hard to underestimate Ciena’s importance as large amounts of data move between servers, storage, and the outside world.

Ceina reported Q1 earnings on March 5, with record revenue and a backlog approaching $7 billion.

The only “problem” in the report is the company’s ability to meet that demand. In the report, Ciena said that it expects there to be supply constraints that prevent it from receiving all of its money. This comes despite accelerating the company’s spending to meet capacity.

CIEN has a consensus price target of $367.56, which is 30% below its current share price. However, prices have been on the rise since “Big Tech” earnings were reported at the end of April. Patient investors should view any pullback as an opportunity to enter CIEN.
