Whenever a singular topic gains this level of attention, it’s instructive to look at how investors develop different types of tunnel vision. If the wave continues, there’s a good chance that while the average person may not know what a graphics processing unit (GPU) is or how it connects to AI, they might very well know that Nvidia ‘makes them’ and that Nvidia is basically the ‘AI company.’

Frequently, we find ourselves trying to remember to step back and think about the broader set of infrastructure that is required for Nvidia’s GPUs to actually be effective at training and running AI models. Nvidia, effectively, designs merely one part of a much longer value chain that builds into the AI ecosystem. It is an important part, and Nvidia is able to extract a significant percentage of the overall economic value, but if the other parts ceased to exist it is also true that Nvidia’s GPUs, by themselves, are not very useful.

Data Centers: Where Are the AI Models Trained and Run?

The software aspect of AI is often conceptualized, but it’s important not to forget the physical aspect. Giant server farms, strategically deployed across the globe, allow the internet to work as we have come to expect, and this infrastructure also allows the largest AI models to be trained and run.

Data centers represent the specific, purpose-built real estate that supports this infrastructure. All the time, there is a race to both expand the computational resourcing per square foot in the existing data centers as well as to expand the overall data center footprint.

Why is this? Well, when was the last time you thought about data storage? We’re all taking more pictures, generating more content and not even paying a second’s thought to storage. We just assume that when we need it, more will always be there.

At WisdomTree, we work closely with CenterSquare, an investment management firm that specializes in real estate assets. They recently put out a short briefing note with a focus on data centers, and we wanted to bring some of that information to our own audience.

Figure 1 provides important context on what the current real estate market looks like, roughly halfway through 2023¹:

• Data centers represent 8.6% of the pie.

• Many people might expect the share of ‘Office’ to be larger, but it is only 2.9%.

• We draw attention as well to ‘Towers, 13.8%’—while we are talking about AI and data centers in this piece, a critical reason why we are doing so regards the speed with which we can send data to different places—cell phone towers and the overall upgrade to 5G infrastructure is an important link in this chain.

Figure 2 takes the two largest data center real estate investment trusts (REITs), Digital Realty Trust and Equinix, and looks at the percentage of annualized rental revenue from cloud/IT providers. CenterSquare wanted to highlight this was due to their belief that it is really these companies that are driving AI and have a strong influence on the equity markets. Some of the names include:

• Amazon.com

• Alphabet

• Apple

• Meta Platforms

• Microsoft

• IBM

• Oracle

If we look at market indexes, like the S&P 500 Index or the Nasdaq 100 Index, many of these firms are responsible for the bulk of their performance in the first half of 2023. Whether or not that exact trend continues, it’s clear that many investors believe these companies will be central in pushing AI forward. Figure 2 indicates how important these firms are to the revenues of the two largest data center REITS.

Figure 2: Companies Driving AI Forward Are Major Data Center Customers

Figure 3 addresses the fact that the hyperscale (i.e., most capable, best infrastructure) cloud providers depend on Equinix and Digital Realty Trust for the majority of their connectivity. It is a similar idea to a key trend in semiconductors, where many firms depend on Taiwan Semiconductor Manufacturing Co. (TSMC) to fabricate the most advanced chips. Space and prime locations for data centers are not unlimited, and even if the degree of specialization is not the same as the case of TSMC, there are benefits to these companies from being able to plug into existing infrastructure from firms that specialize in exactly that, as opposed to building each and every data center on their own.

Bottom Line: New Economy Real Estate Represents a Totally Different Way to Think about Artificial Intelligence in 2023

The WisdomTree Artificial Intelligence & Innovation Fund (WTAI) has returned nearly 40% from December 31, 2022, to June 16, 2023. The strategy, designed to track the returns of the WisdomTree Artificial Intelligence & Innovation Index, focuses on those companies that are more directly developing different types of AI and pushing increased capabilities across the market. In short, exactly the topics that have been considered among those ‘most in favor’ in the first half of 2023.

Performance is historical and does not guarantee future results. Current performance may be lower or higher than quoted. Investment returns and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance data for the most recent month-end is available here.

On the other hand, two of the larger exposures within the WisdomTree New Economy Real Estate Fund (WTRE) are focused on data center REITs and cell phone tower REITs—something around 40%. It is not likely these companies would or should ever generate the level of excitement of say, an Nvidia, but we simply caution investors against forgetting about them, in that we believe their functioning well does in fact make Nvidia’s product more valuable.

Additionally, we believe that some investors will be looking at the first half of 2023—still excited about AI—but hesitant after such strong returns in the more direct AI strategies. WTRE is clearly different, and it may be worth at least some consideration.

WTAI: There are risks associated with investing, including the possible loss of principal. The Fund invests in companies primarily involved in the investment theme of artificial intelligence (AI) and innovation. Companies engaged in AI typically face intense competition and potentially rapid product obsolescence. These companies are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Additionally, AI companies typically invest significant amounts of spending on research and development, and there is no guarantee that the products or services produced by these companies will be successful. Companies that are capitalizing on innovation and developing technologies to displace older technologies or create new markets may not be successful.
