Are AI Bubble Concerns Warranted or Overblown?

Is there an AI bubble? We've all heard the bull case for AI, that we're in the early innings of a technological revolution that will change the world. And the companies leading this revolution will generate tremendous returns for their investors.

But after years of heavy spending and rising stock valuations, we're starting to hear a lot more skepticism. So are there signs of a bubble? And if we are in a bubble, what does it mean for investors? I'm Alison Nathan, and this is Goldman Sachs Exchanges. Each month, I speak with investors, policymakers, and academics about the most pressing market-moving issues for our top of my report from Goldman Sachs Research. This month, I spoke with two of my colleagues here in Goldman Sachs Research.

our U.S. Internet Equity Research Analyst, Eric Sheridan, and our U.S. Software Equity Research Analyst, Cash Rangan. I started by asking Eric and Cash about where the AI buildout stands today and how that compares to expectations. On the infrastructure layer... The amount of capital and the amount of spend has surprised to the upside. That level of spend short term is mostly tied to the fact that demand for these services, the compute need.

generated by you querying GPT is outstripping the available capacity. So infrastructure has surprised to the upside on the need for capital to meet the demand for services. The platform layer arguably is the handful of companies that are transitioning from just running foundational models. to either building API solutions or applications on top of the foundational model. And there's only a handful of those companies that have started to emerge that have the scale of capital and talent.

to execute against that. We've seen more applications emerge on the consumer side, mostly through the usage of ChatGPT and Google Gemini by consumers. And I'll leave it to Cash to talk about the application side. for enterprise. Right. Okay. Cash, I do want to get your take. The infrastructure build-out has gone on a lot longer than anybody expected. But at the same time, I look at my coverage area, how this activity at the infrastructure layer...

is percolating up to the platform layer is starting to become more discernible. The platform layer is in a much better position today than it was a year ago, two years ago. The disappointment has been at the application layer. To Eric's point, a lot of consumer applications, they're exemplifying the value of AI, whether it's chat GPT or cloud application at the consumer level. But at the enterprise level, end user level, there are some signs of life.

We're not where we expected. If you asked me to guess at where these companies would be today, I would have given you a number and we would be well below the number. But we're getting there. It's not where we expected it to be a year ago, two years ago, but relative to where we were. Six months ago, nine months ago, we're starting to see these applications. But ultimately, Eric, there is so much CapEx going in, so much more than we even thought when there was amazingly high numbers last year.

the return potential. Has that grown too? So I'll make a couple of points. The rise in spending in aggregate is a very large number and it has resulted in a number of investors. really asking the ROI question. That question is only going to build in scale, not abate in scale. And I really don't think there's any incentive for anyone to stop playing offense today.

Nvidia recently put out a number of $3 to $4 trillion between now and the end of the decade. I think most investors we talk to would struggle. to justify the return profile on three to four trillion of cumulative spend unless AI is the main driving factor in an enormous amount of the economic output of society in some sort of end state. That being said, there have been computing cycles

Folks like me have not been able to look out 6, 7, 8, 9, 10 years and say, this is what it's going to look like. At different points in time, it was we overbuilt to desktop computing. and then netflix was created and the browser wars happened and the uh portal wars happened and all of those things drove a lot more desktop usage

There was nobody when spectrum and towers and wireless was being built that thought 3 billion people would have smartphones with this battery capability and power capability. Things do change. And I think the most. leading-edge companies invest with confidence against the long-term time horizon. The questions from investors will continue to rise, and I think if the dollars keep rising...

I'll be brutally frank, will struggle to answer them with what we know today. And typically, through every computing cycle I've ever analyzed, that leads to a trough of disillusionment at some point, where either the spend or the adoption rate or some combination of the two don't give a satisfactory six, 12-month answer.

And are we going to avoid one this time? I would be shocked if we avoided one. In any technology cycle that we've covered, there are typically two to three companies that earn their cost of capital. and earn an excess return on that cost of capital. The idea that there are four, five, six, seven companies in an industry that do something and they all earn an excess return in the same vertical or the same product is...

Not typical. And I don't know why this should be any different. Obviously, we're having this conversation because the concerns that there is a bubble forming in the markets when you see how mega cap tech. has performed the valuations where they are today. Do you think concerns that we are now in bubble territory are there? And what are you watching to assess that? I'm not trying to be flip about this question.

There's been more talk of a bubble in a continuous nature for three years. Two other bubbles I lived through, there wasn't this much talk of the bubble while we were in the bubble. So look, do I see signs that point me back to the late 90s or the 07 time period? Sure. Private market valuations are well ahead of public market valuations. Public market valuations are above historical.

norms, but they're also below the peak of public market valuations that you saw in 99 and 2000. Capital market activity is still well below the levels that were seen in 2020, 2021. 2007, 2008, 1998, 1999. So I would argue there are signs. of exuberance there are signs that rhyme with past periods of time but i wouldn't necessarily align it perfectly with some of the lessons we've learned in prior periods at least not yet now that's arguably a duration

narrative that I'm saying that we're just not there yet. That would be one framing I would give the other that is a little bit different than prior periods. Typically, the companies that generate no profits, and in 1999, it was companies that generated no revenue, are the ones that were driving the most exuberant valuations in the market. Most of those companies generate outsized levels of free cash flow and buy back their stock and pay dividends.

There were very few companies buying back their stocks and paying dividends in 1999. So there are some key distinctions I would keep in mind as opposed to just drawing a straight analogy. Pastor, do you have any thoughts about bubble concerns? signs that we may or may not be in one? Certainly not in the stocks that I cover. A lot of software stocks are trading at depressed valuations because of what AI could presumably do to their end markets, whether it's job dislocation.

towards consumption or AI enables you to write software in a cost-effective manner because you got pipe coding and other things that obvious the need to buy an application software package from the likes of Salesforce, et cetera. So we're going through an existential crisis right now, that there is a decided discount rather than a premium. And something that is so different about this cycle, which should make even somebody that's normally a bit circumspect.

a little bit less cautious, is where is this capital coming from? American Art lived through the late 90s, and we saw the capital that was deployed in high-risk projects was venture capital and private capital. This time... The capital is coming from well-heeled, deep-pocketed hyperscaler giants. Their cost of capital is quite low. Their ability to take risk with this amount of money is quite high. And even if it means a couple of cycles of trying and...

finding out what the best way to extract value from AI, they can do it. So the availability of so much capital coming from a very different audience, a different set of investors. makes the cycle a little bit different and more tolerant of snafus and missteps which we will have plenty of these things before we nail the ultimate ai business model

But we're starting to see a new development whereby entities are being put together that are funded with 80% debt, 20% equity. And even within the equity piece, there is a collateral that's backed to a sponsoring entity. And these entities are able to issue debt at very low cost of capital. But something we should be aware of as a risk factor is that leverage in the system is starting to emerge. We have to make sure that...

the system works, that ultimately these companies that are driving the need for capital, whether it's the foundation model companies, whatnot, are able to hit their numbers. We need to be carefully monitoring if this math works. Because there's a lot of leverage upon leverage on top of a low gross margin business model. So active monitoring needed. Right. And let me put that back to you, Eric. Because ultimately, at the end of the day, we have...

NVIDIA investing $100 billion in OpenAI. And then we have OpenAI pledging $300 billion, which they don't really have on cloud compute from Oracle. And then Oracle's buying NVIDIA chips. And then NVIDIA is investing in Intel. I mean, the circularity of all this, does that make you nervous at all? It does. As I said, I think there are things you can point to going on right now that rhyme.

with 1998, 1999, that would be an example of it. I started my career as a telecom analyst and a telecom investor in the late 90s and early 00s.

the era of global crossing and level three and quest and these companies were trading capacity with each other using debt and one person's revenue was another person's capacity and vice versa and when the debt curve got too high it all fell apart and when you untangled all the revenue there was nowhere near the revenue you thought there was at the end of that rainbow that capacity was eventually absorbed

by 2003 and 2004 and 2005. But depending on where your entry point was in the market, your return could have been quite low for very long periods of time. When you start seeing debt... when you start seeing companies investing in other companies, when you start seeing suppliers invest in a company that delivers capacity.

investors are naturally and correctly asking questions about untangling at all and then making sure that there isn't compounded effects that can be built up in the system. Very last question, which is, Eric, what would make you less optimistic? I continue to monitor rise in utility, rise in adoption, monetization and free cash flow. I mean, at the end of the day. It will be very hard to argue if companies spend in a way that eventually puts their free cash flow generation in real risk.

And that typically can be a tipping point in the market. People cutting dividends, cutting buybacks, things like that. Excessive use of debt. Those are things that I am watching for. And Cash, what would make you less optimistic? I'd go back to the point that I made earlier, the beginnings of a credit cycle where new entities are being funded with a lot of debt as opposed to cash from the balance sheet. Less worried about the hyperskillers, but more worried about the collateral damage in case.

Credit cycle does not really cooperate. That's what I'd be watching. That cycle does not cooperate. It will have a ripple effect through the rest of the tech ecosystem. Let's leave it there.
