Owning the buildings AI runs in

There are two ways to invest in the AI buildout. You can own the chips and equipment that do the computing, or you can own the real estate that holds all of it. Data center REITs, real estate investment trusts such as Digital Realty and Equinix, are the second path. They are the landlords of the AI boom, collecting rent on the buildings where the world’s most valuable workloads actually run.

That landlord model is the cleanest, most diversified way to own AI demand, because a REIT’s tenants are the cloud giants and enterprises that have already committed to spending. It is also the sharpest contrast to the Homestacks pitch, which argues that some of this demand will stop renting the big campus and move into a small appliance on a new home instead.

How the REIT model works

A data center REIT develops or acquires facilities, then leases space, power, and cooling to tenants. The tenants are usually hyperscale cloud providers or large enterprises, and they sign long leases because moving computing workloads is expensive and risky. The rent covers the building, the electrical infrastructure, the cooling, and the security, and because REITs are required to distribute most of their taxable income to shareholders, they tend to carry above-average yields.

The reason these names have done so well in the AI era is pricing power. Demand for the newest, most power-dense facilities is running ahead of supply in the major markets, which lets landlords push rents higher and lock in longer terms. The trade-off is capital intensity: these buildings cost hundreds of millions of dollars each, and a landlord that overbuilds into a cooling market is left carrying empty, expensive space.

Where Homestacks breaks from the landlord model

The Angel Publishing Homestacks promotion makes a specific claim: that giant centralized data centers are hitting power, water, and heat limits, and that AI compute will therefore migrate to a distributed appliance installed on new homes. The real product behind the name is SPAN’s XFRA, an outdoor unit about the size of an air-conditioning compressor that pairs NVIDIA Blackwell GPUs with a smart electrical panel and a home battery. SPAN covers the host homeowner’s power and internet bills and installs the battery and panel at no charge.

The first pilot is about 100 units in build-to-rent communities in Arizona and Nevada, built with homebuilder PulteGroup. SPAN has raised roughly $500 million and took a $75 million strategic investment from Eaton. The careful detail is that SPAN’s own press release describes XFRA as a way to augment centralized data centers, not replace them, and NVIDIA’s involvement is as a chip supplier rather than an investor. That gap between the headline and the product matters, because the REIT thesis and the Homestack thesis point in opposite directions for the future of the big campus.

The three picks that are not REITs

The promotion’s three supply-chain names are not real estate companies at all. nVent Electric (NVT) builds the enclosures and housings that protect electrical and networking equipment, with data centers near 40% of revenue. Generac Holdings (GNRC) brings the home-energy angle through batteries, software, and grid controls, plus a roughly $700 million data-center backup-power backlog. Vistra Corp. (VST) is the Texas power producer with purchase agreements with Amazon and Meta.

Each is a real, reasonably valued business tied to the same demand that fills REIT buildings, but none of them depends on a 100-unit housing pilot. We walked through the equipment side in our breakdown of the data center stocks behind the AI Black Paper pitch, and the facilities themselves in our explainer on the Frontier AI buildout.

The income angle the landlords offer

One thing a REIT gives an investor that a supplier does not is current income. Because a data center REIT must distribute most of its taxable income as dividends, it tends to carry a meaningful yield, and that yield is backed by long-term leases with creditworthy tenants. For an investor who wants exposure to the AI buildout without relying entirely on price appreciation, that regular distribution is the appeal.

The growth names in the Homestacks pitch do not offer the same thing. nVent Electric (NVT), Generac Holdings (GNRC), and Vistra Corp. (VST) are all growth-oriented businesses, and while Vistra and Generac pay some income, their investment case rests on earnings growth rather than on a landlord-style distribution. That is the honest difference between the two paths into the same theme.

Neither approach is right or wrong. The REIT is the steadier, income-oriented way to own the buildout, while the promo’s picks are the higher-growth, higher-volatility way. Our companion piece on the best data center REITs walks through the landlord names themselves.
