Episode summary
A Layman Thinks About AI
Summary
Howard Marks argues that AI is too important for investors to ignore, but too unpredictable to treat like a normal growth story. He frames the memo as a set of 11 investment questions about what AI can do, who will profit, how competitive the industry will be, how profitable the businesses will become, and how much capital and debt the buildout will require. His central point is that investors must think in probabilities, not certainties, because the number of variables is unusually high and the odds of being right on all of them are low.
Marks says the technology itself is likely to be powerful and consequential, but the economics are far less clear. He worries that AI could become a commodity, that frontier labs and hyperscalers may not keep today’s advantages, and that earnings are hard to forecast even five years out. He also flags the huge expansion in data centers, the concentration of market gains in a small group of AI-linked stocks, and the growing importance of AI-related debt issuance.
On the credit side, he sees AI as a major new source of borrowing, with hundreds of billions already flowing into investment-grade and high-yield markets. That raises questions about leverage, refinancing, circular transactions, and whether the cost of capital will rise. His conclusion is not to avoid AI, but to approach it with calibrated humility, careful pricing, and disciplined position sizing.
Key takeaways
- Howard Marks says AI is the most consequential and least predictable development for investors in at least a generation.
- He thinks the main investment question is not whether AI matters, but who captures the profits from trillions of dollars in capital spending.
- He warns that AI-related debt could become a major market force, with roughly $600 billion issued globally this year and more to come.
- Marks sees frontier labs, hyperscalers, chips, and data centers as having very different predictability and risk profiles.
- He argues that uncertainty does not justify paralysis; investors should demand a low enough price and size positions accordingly.

“The key observation is that the factors our economy and markets depend on today are relatively undiversified”
“The conclusion I draw from my conversations with people I consider knowledgeable is that at this point answering this question is largely a matter of faith”

How the episode opens
This is the memo by Howard Marx. A layman thinks about AI. Should we invest in artificial intelligence and can we do so intelligently?
That's what I'm going to address in this memo. On one hand, I'm not a tech person and I don't claim to have above average knowledge of artificial intelligence or technology investing for that matter. On the other, AI is the biggest development of our time and could be one of the most impactful things the world has ever seen.
So, investors don't have the option to abstain from thinking about it. With that disclaimer, I'm going to share my deliberations, put forth the questions I'm wrestling with, not all of which are directly relevant to investing in AI, and provide my thinking about them. While my limited knowledge prevents me from definitively answering these questions, I hope to provide a service by assembling them in one place.
And while news on AI comes hot and heavy these days with security prices for AI and AI adjacent companies gyating up and down, I'm not going to try to keep up since what I have to say relates to the long-term outlook for AI, not what security prices will be tomorrow. Investing consists of just one thing, positioning capital to benefit from future events. And most investors cope by relying on forecasts.
But not everything is equally predictable and not all forecasters are equally skilled. Thus, to invest in AI based on expectations about the future, and I think that's all we have, we must consider both what we think the future may hold and the chance we can get it right. I've written in the past about the fact that people who engage in top-down investing have to be right about the outlook for the economy, the industry, the company, and the market.
