I'm Ariana Salvatore, Head of Public Policy Research at Morgan Stanley. Today, what the midterms could mean for the AI investment cycle. It's Wednesday, October 7th at 10am in New York. I've spoken on this podcast before about the broader implications of the midterm elections. This time, I want to go a little deeper on what they could mean specifically for AI sentiment. We think about that through two separate channels. The first is data center opposition, where we do think the elections can be an important catalyst. The second is broader AI safety and regulation, where we think the election outcome matters much less. And that distinction is important. It suggests that the midterms are more likely to influence investor confidence in the pace and the durability of AI infrastructure spending, rather than fundamentally rewriting the rules governing AI. Let's start with data centers. Our base case is still a conditional build-out. We still expect substantial AI infrastructure investment, but increasingly subject to conditions around things like power costs, grid investment, siting, permitting, water use, and community impact. We don't expect a broad federal pause on data center development. AI compute is increasingly being viewed in Washington as strategic infrastructure, particularly when you consider competition with China. So, we think that national security framing should remain supportive of the build-out. But here's the important point for these elections. Many of the policy levers that can actually delay a project sit well below the federal level. Think about things like interconnection approvals, large load electricity tariffs, zoning, water permits, and tax abatements. Those are all generally controlled by states, utility commissions, and local governments. So, when it comes to AI infrastructure, we actually think governors, state legislatures, and public utility commissions may ultimately matter more than control of any one Senate seat in particular.And that brings us to sentiment. At the federal level, we think a Republican sweep would likely be the most constructive outcome for AI infrastructure sentiment. Now, that's because investor
