Best Data Center Stocks

Last updated June 2026

Short answer

There is no single list of best data center stocks, because the right holdings depend on your goals and no one can predict prices. What does anchor the theme is a mix of companies across the layers of the AI-driven buildout: data center REITs that own the buildings (DLR, EQIX), power and cooling (VRT, ETN, GEV), networking and compute (NVDA, ANET, SMCI), and electrical construction (PWR). The useful move is to treat a list like this as a research starting point and build a diversified portfolio from it, not to buy one name. Walnut, an AI investing app, can compare these names against your existing holdings. This page is descriptive and informational, not investment advice.

The AI boom is, underneath the headlines, a construction project. Training and running large models takes enormous, dense computing, and that computing has to live somewhere, draw power, and stay cool. So the data center theme is not one kind of stock but several: the REITs that own the buildings, the companies that supply power and cooling, the utilities and contractors that feed the grid, and the chips and servers that do the work. This guide groups the names people most widely hold and discuss for that buildout by the role each plays, explains what each one represents, links each to a fuller page, and then shows how to turn a list like this into a portfolio instead of a single bet. Nothing here is a recommendation to buy or sell, and Walnut is not an investment adviser.

What is the data center buildout thesis?

The thesis is simple to state and easy to over-apply. Artificial intelligence needs compute, compute needs data centers, and data centers need real estate, power, cooling, and a grid that can deliver electricity at a scale the system was not built for. That demand shows up at every layer at once, which is why the theme spans REITs, industrials, utilities, and chipmakers rather than a single sector. Three things are worth holding in mind.

  • The bottleneck has moved to power. Chips are abundant relative to the electricity needed to run them, so power generation, electrical equipment, and grid construction have become as central to the theme as the silicon itself.
  • The layers behave differently. REITs act like real estate, equipment makers track capital spending, and chip and server names are the most volatile. Owning across layers spreads risk versus concentrating in one.
  • It is still one theme. Much of the group depends on continued heavy AI capital spending, so these names move together more than their different businesses suggest. A slowdown in that spending would hit many of them at once.

None of this is a recommendation. It is the framework most long-term investors use to read a list like the one below without treating it as a set of hot tips.

What data center stocks are widely held in 2026?

Below are the data center stocks most widely held and discussed going into 2026, grouped by the role each one plays in the buildout. For each, the note explains what the business is and why it is commonly held, not whether you should own it. Every name links to its own page with the deeper detail.

Data center REITs and landlords

The most direct way to own a data center is to own the buildings. These real estate investment trusts develop and lease the facilities, the power, and the interconnection that cloud providers and enterprises rent, which is why they anchor most data center baskets going into 2026.

  • Digital Realty (DLR). Digital Realty is one of the largest data center REITs, leasing colocation and hyperscale space, power, and interconnection worldwide under its PlatformDIGITAL brand. It is widely held as a landlord play on AI demand, with revenue growing in the mid-teens and record hyperscale leasing reported in early 2026.
  • Equinix (EQIX). Equinix operates a global network of interconnection-dense colocation facilities and leases space, power, and cooling to enterprises, cloud providers, and networks. It is commonly held as the interconnection hub of the internet, a different flavor of data center REIT from the hyperscale-focused names.

Power, electrical, and cooling

AI racks draw far more power and throw off far more heat than traditional servers, so the equipment that delivers electricity and removes heat has become one of the most discussed parts of the buildout. These names are commonly held to express the data center theme through its physical bottlenecks rather than through chips.

  • Vertiv (VRT). Vertiv makes critical digital-infrastructure equipment for data centers, including power distribution, uninterruptible power supplies, thermal management, and rack systems, and has expanded heavily into liquid cooling for high-density AI racks. It is widely held as a direct beneficiary of AI-driven data center capex, reporting sharp sales growth into 2026.
  • Eaton (ETN). Eaton supplies electrical power-management gear, switchgear, and distribution equipment that data centers need to scale, and has reported record sales and a fast-growing electrical backlog. It is commonly held as a diversified industrial way to own the electrification side of the data center buildout.
  • GE Vernova (GEV). GE Vernova builds the gas turbines, grid equipment, and electrification hardware that utilities need to add generation and transmission for surging data center demand. It is widely held as a play on the power-generation constraint behind the AI buildout, one step further upstream than the in-facility equipment makers.

Networking and compute

Inside the building, data centers run on accelerators, switches, and servers. These are the silicon and hardware names commonly held to express the AI buildout through what actually does the computing, the part of the theme most directly tied to model training and inference.

  • NVIDIA (NVDA). NVIDIA designs the GPUs and the CUDA software that train and run most large AI models, plus the networking that ties accelerators into clusters. It is held heavily in nearly every data center and AI-infrastructure basket and sits among the largest companies in the S&P 500.
  • Arista Networks (ANET). Arista builds high-throughput Ethernet switching that connects the GPUs inside AI clusters, with hyperscalers among its largest customers. It is widely held as a networking pick-and-shovel play on data center scale-out rather than on any single chip.
  • Super Micro Computer (SMCI). Super Micro assembles the servers and rack-scale systems, including liquid-cooled designs, that house AI accelerators for data center operators. It is commonly held as a direct server-buildout name, though it is more volatile and has faced governance and accounting scrutiny.

Electrical construction and grid buildout

Before a data center draws a watt, the grid connection, substations, and transmission have to be built. This is the construction-and-engineering layer of the theme, commonly held as a more diversified way to own the spending without betting on a single chip or facility.

  • Quanta Services (PWR). Quanta Services provides infrastructure construction and engineering for electric power, including transmission lines, substations, and grid connections that data centers depend on. It is widely held as a contractor play on the grid upgrades and electrification spending the AI buildout requires.

How do you build a portfolio from these instead of buying one?

A list of stocks is an input, not a portfolio. The difference between the two is structure: which roles you want exposure to, how much weight each name gets, and the discipline to keep no single position from dominating. The repeatable way to do it looks like this.

  • Pick a thesis. Decide what view you are expressing. Data center landlords plus power equipment, for example, is a very different portfolio from all chips and servers.
  • Choose the names that express it. Use a list like this to fill each role with a handful of holdings rather than one, so a single company stumbling does not break the thesis.
  • Set target weights. Assign each name a percentage that sums to 100, so concentration is a choice you made rather than an accident of which stock ran up.
  • Compare against the S&P 500. Check how the mix would have tracked the benchmark, because a single-theme tilt like this one is concentrated and should earn its keep versus just holding the index.
  • Place the trades and review. Buy to your targets, then revisit periodically as weights drift away from where you set them.

This is exactly what Walnut is built for. You create a thematic basket from the stocks you choose, set a target weight for each, see how the basket would track against the S&P 500, and place trades you approve yourself at your own broker. Walnut frames each holding against the S&P 500 and shows how the mix is concentrated, so the portfolio is a deliberate structure rather than a pile of separate bets. Walnut does not tell you which stocks to buy.

How we chose what to feature

To be clear about method, since framing matters on a page like this: this is not a prediction and not a ranking. We did not forecast which stocks will rise, score them, or order them by expected return, because no one can do that reliably. We featured names on three descriptive criteria instead.

  • Widely held. Each is a large, broadly owned company that appears across data center and AI funds and mainstream portfolios, so the page reflects what people actually hold rather than obscure tips.
  • Role-representative. Each name was chosen to illustrate a layer of the buildout (REITs, power and cooling, networking and compute, electrical construction) so the list teaches how the theme fits together, not which single stock to chase.
  • Liquid and established. We featured large, liquid, well-covered companies so the descriptions can lean on durable business facts rather than hype.

The result is a map of the data center buildout and how to think about it, not a buy list. Treat every name as a starting point for your own research. Facts about companies change; verify current details before you act.

The bottom line on data center stocks

The honest answer to “what are the best data center stocks” is that there is no single list, because the right holdings depend on your goals and no one can predict prices. What anchors the theme is a spread across its layers: REITs that own the buildings like Digital Realty and Equinix; power and cooling like Vertiv, Eaton, and GE Vernova; networking and compute like NVIDIA, Arista, and Super Micro; and the electrical construction behind it all like Quanta. The useful move is to treat a list like this as research and build a diversified, weighted portfolio from it rather than buying a single name. Walnut helps you turn that into a thematic basket you control. It is not an investment adviser, and nothing here is a recommendation.

FAQ

What are the best data center stocks for 2026?

There is no single list of best data center stocks, because the right holdings depend on your goals, time horizon, and risk tolerance, and no one can predict prices. What this page shows instead is the names most widely held and discussed for the AI-driven buildout, grouped by role: data center REITs (DLR, EQIX), power and cooling (VRT, ETN, GEV), networking and compute (NVDA, ANET, SMCI), and electrical construction (PWR). Treat them as a research starting point, not recommendations. Walnut is informational and is not an investment adviser.

What is a data center stock?

A data center stock is any company whose value is tied to the facilities that house computing and storage. That spans several distinct roles: the REITs that own and lease the buildings (Digital Realty, Equinix), the equipment makers that supply power and cooling inside them (Vertiv, Eaton), the utilities and grid suppliers that feed them electricity (GE Vernova, Quanta), and the silicon and servers that do the computing (NVIDIA, Arista, Super Micro). Each role behaves differently, which is why grouping matters.

Why is there a data center buildout, and what is driving it?

The driver is artificial intelligence. Training and running large AI models requires enormous, dense compute, so cloud providers and enterprises are spending heavily to build new data centers and retrofit old ones. AI racks draw far more power and generate far more heat than traditional servers, which is why the buildout shows up not just in chips but in real estate, electrical equipment, cooling, and the power grid itself. This is descriptive, not a forecast that the spending will continue.

Why group data center stocks by role instead of ranking them 1 to 10?

A ranked hot-tip list implies someone can order stocks by future return, which no one can do reliably. Grouping by role (REITs, power and cooling, networking and compute, electrical construction) is more useful because it shows what each name actually represents and how they relate, which is what you need to build a diversified portfolio rather than chase one pick.

Are data center REITs different from the chip and equipment names?

Yes, meaningfully. REITs like Digital Realty and Equinix own and lease the buildings, so they behave more like real estate, with rental income, leverage, and sensitivity to interest rates. The equipment, networking, and chip names like Vertiv, Arista, and NVIDIA are operating companies whose revenue tracks data center capital spending more directly and tends to be more volatile. Owning across both spreads risk versus betting on a single layer of the theme.

Is investing in data center stocks risky?

Every stock carries risk, and data center names have theme-specific ones. Much of the group depends on continued heavy AI capital spending, so a slowdown in that spending would hit many of them at once, since they move together more than their different businesses suggest. Power and grid names face permitting and construction risk, and some hardware names are more volatile or have faced governance scrutiny. Nothing here is advice; Walnut is not an investment adviser.

How do I turn a list of data center stocks into an actual portfolio?

Decide which roles you want exposure to, choose the names that express each, set a target weight for each so no one position dominates, and place the trades at your broker. Walnut does this as a thematic basket: you set targets, see how the mix would perform against the S&P 500, and approve any trades yourself. The list is the input; the portfolio is the structure you build around it.

Does Walnut recommend which data center stocks to buy?

No. Walnut is not a registered investment adviser and does not tell you what to buy. It lets you build a thematic basket from stocks you choose, set target weights, see how the basket would track against the S&P 500, and place trades you approve at your own broker. Every page here is descriptive and informational, not a recommendation.

From here you can explore the data center and power theme or the broader AI infrastructure theme, dig into any individual stock, or see the best ETF in every category for instant diversification.
