Ariana Salvatore: Today: the politics, economics, and market implications of America's AI data center build-out. 

It's Tuesday, August 4th at 10am in New York. 

AI infrastructure spending is becoming a major force in the U.S. investment cycle. But as you've heard on this podcast in recent weeks, local resistance to data centers is growing, and projects worth hundreds of billions of dollars are being canceled or delayed. 

More than 300 local moratoria have passed since 2023, and restrictions now touch 40 states. Now, most are temporary pauses, not outright bans, but the community opposition is tangible. 

For investors, the key question is how these local pressures shape the broader build-out. So, I wanted to talk to you both because, Sarah, you've looked at this on the local level, and Michelle, you've been leading some of our thematic work on this topic. 

So, Sarah, maybe we'll start with what happens when a data center comes to town. How does a large project ripple through a local economy, especially when so much of the expensive hardware is imported? 

Sarah Wolfe: I think we need to look at the data center build-out from two lenses. First, at the national level, and then what's really happening at the local level, county by county. 

So, at the national level, the headline investment can actually overstate the contribution to GDP because a lot of the components that go into data centers – think chips, servers, networking equipment – most of that is imported. So, it's actually an offset in the GDP accounting.

But when we analyze the AI build-out at a local level, we see that the town experiences the project very differently. A data center still needs a physical shell, concrete, steel, electricians, construction workers, and then the restaurants that feed the construction workers. 

So, the local multiplier depends on how much of that spending around the data center stays nearby. Workers are going to get paid, local suppliers win contracts, and nearby businesses will see more demand. And then importantly, governments may collect more property and business tax revenue. When we look at county-level research on the AI data center build-out, we do see positive effects on employment, business formation, wages, income, and tax returns. 

So, these data centers are significant. They do have significant multipliers. But we need to dig a little bit deeper and look at how it affects different counties. 

Ariana Salvatore: So, it sounds like there are some local economic benefits. How durable do you think those are? 

Sarah Wolfe: Some of the effects are durable and some aren't. The largest and most important effects come through employment in the near term. If we look at the construction phase of these projects, let's look at a data center that's 250,000 square foot, in Virginia. That supports more than 1,500 workers during construction. 

But then, if we look at what happens after construction is done, there's only about
