$31B Investor on AI Infrastructure, Private Equity, and Secondaries
How I Invest With David Weisburd
· · 1 hr 8 min · Hosts: David Weisburd · Guests: Stuart Waugh
Summary
Stuart Waugh argues that the biggest AI opportunity is not in AI companies themselves but in the infrastructure that makes AI possible: power generation, transmission, data centers, communications networks, and related assets. He says Northleaf’s view is built on long-term trends rather than short-term market noise, and that governments increasingly lack the balance-sheet capacity to fund this buildout alone, leaving a large opening for private capital.
He frames infrastructure as a portfolio category with essential services, predictable cash flows, long asset lives, low correlation, and often inflation linkage. In his view, AI is only one catalyst: urbanization, energy security, deglobalization, and refurbishment of aging assets are all driving demand. He says Northleaf estimates roughly $40 trillion of addressable infrastructure investment over the next 10 years and sees the middle market as especially attractive because larger managers have moved upmarket.
Waugh also says secondaries have become a mainstream portfolio management tool rather than a distressed seller’s solution, with relationships and proprietary information still creating an edge. On private credit, he says institutional demand remains solid despite retail market stress, and he returns repeatedly to the idea that boring, patient, long-term investing is often the advantage.
Key takeaways
- Stuart Waugh says Northleaf sees AI infrastructure demand as a power-and-connectivity story, not just a data-center story.
- He says Northleaf estimates about $40 trillion of addressable infrastructure investment over the next 10 years in its core markets.
- He argues infrastructure offers long-duration cash flows, low correlation, and inflation linkage, making it a portfolio diversifier.
- Waugh says secondaries have shifted from opportunistic distress trades to routine portfolio management, with GP relationships still a key edge.
- He says private credit remains attractive for institutions even as retail-oriented parts of the market face sentiment pressure.

How the episode opens
At Northaf, you manage $31 billion and you believe today the biggest opportunity isn't in AI. Why is that? — That's because we're focused on the enablers of AI, principally infrastructure. And if you think about it, without infrastructure, AI doesn't happen.
Everyone uses this term infrastructure. What does it mean exactly? — For us, it really means assets and projects that provide essential services without which you just don't get a productive modern society. So it really is the foundational building blocks of societal progress and and ultimately societal prosperity.
And what's the investment case for infrastructure that's supporting the AI boom?
The example I always think about if you go back to the gold rush in history is the picks and the shovels and the mules. So if you think about what does AI really need? AI needs power.
So that means both generation as well as transmission of power. It actually needs the data centers obviously and there's been lots of attention paid to the physical construction of data centers but then it also needs the digitization and the communication. So it needs transmission, it needs cell towers, it needs access that you and I now take for granted in terms of where we can get information and communication.
So you think about all of those building blocks that are necessary for AI. That's where infrastructure comes in and that's where the massive demand for capital we see both now and well into the future.
And how would you bucket those different investment opportunities? — We think about infrastructure as having a series of characteristics. So essential services are critical like what is it that really is foundational to the asset? Why does it exist? How much would people notice if it ceased to be?
