When you're running a business, the best days are the ones where priorities stay on track. For midsize and large companies, risk can affect multiple parts of the organization at once, from property and liability to cyber and regulatory challenges. At that level, managing risk becomes an ongoing discipline. At the Hartford, the focus is on helping businesses manage risk before it turns into something more disruptive. And when losses do happen, that work is paired with insurance coverage shaped by years of underwriting, risk engineering and claims experience.

Foreign. Welcome to the Merlin Talks Money Market Wrap, where we talk about the biggest moves in markets this week and what's been driving them. I'm John Stevick, senior reporter and author of the Money Distilled newsletter, and joining me in the studio today is Bloomberg's private company's managing editor, Neil Callanan. Neil covers hedge funds, asset management, and real estate in emea. So in today's show I basically wanted to talk about the AI industry. I wanted to give a structure of what it's actually about, lay it out so that you can understand it better who's producing the chips and who's producing the models, and then wanted to look at how that's funded and why. There are some concerns about perhaps the circularity of some of the deals in the industry, and Neil has written a lot about that. Thanks very much for being with us today, Neil. It's great to have you on the show.
Neil Callanan
Thanks for having me, John.
John Stevick
Not at all. We're recording this on Wednesday. And probably the biggest story so far this week has been the route in the South Korean Cosby Index. Basically, this is driven by the fact that cospi is. Half of it is comprised of two stocks that are related to the AI boom, and that's sk, Hynix and Samsung. Also, there is an element of retail investors getting in over their heads because they've been able to buy all these leveraged ETFs. And so the cost went up a lot and then down a lot. One of the stats that really jumped out at me is that it's actually still up 35% on the year, but in the last month it's fallen 34%. Okay, that's a proper roller coaster moment. But does this tell us or what does this suggest is about the overarching AI story? Because it's not just about Korean leverage. There's other stuff going on too, isn't there?
Neil Callanan
Absolutely. And Korea, in a way, is a special case because Korea has almost gamified the finance industry and the stock market. And you mentioned the leverage ETFs, but they've been big on crypto and tether and things like that, stablecoins for a long time. And a lot of those investors in retail have grown up very accepting of those levels of risk. And in many cases, it has paid off. So, as you said, the cost is still up this year, despite the rout in recent weeks. But what is driving a lot of the change at the moment is the fear that China is catching up. And China's emergence in AI, which was always going to happen, but perhaps faster than people thought, is really concentrating minds at the moment. And we have seen in the past when deepsea came out of nowhere and released its models, the market disruption that that caused. And now we're going through a kind of second bout of that, where in the space of just over a week, you've seen massive progress in terms of memory chips, in terms of language models. And so China is definitely emerging. And one of the things around all the spending that we're seeing in AI is the assumption is that people are willing to pay for it and we pay a for it going forward. And then suddenly if you have these cheaper models coming out of China and people start switching to that, then what happens with the names we're all familiar with, like OpenAI and anthropic. And so there's definitely fears in the market about that at the moment. And I think People are definitely taking pause globally as a result of that. At the same time, a lot of this money is going to be spent. There is an investment case for it. It's whether it' getting ahead of itself at the moment. And certainly in terms of valuations, it did seem to be getting steamy at one point this year.
John Stevick
Yeah, I mean, I thought we'd just kind of lay out roughly the AI industry and the business model because I think a lot of the time we sort of talk about AI and it's quite an amorphous kind of blob. And a lot of time we're thinking about ChatGPT and we know Nvidia is in there somewhere and all the rest of these things. But so I always kind of looking at it and actually I was talking to AI about it and getting a sense of what the kind of value chain is. So you've got the machines that make the. So you've got the companies that make the machines that make the chips. And that's like your SML that makes the kind of lithography machines. And then you get the chip foundries themselves. And that's like the Taiwanese company tsmc, you've got chip designers and that's Nvidia. So they're the ones that basically do the kind of value add element, isn't it? It's like they're making the brains for these things. Then all of these chips go into big AI hotels, the kind of data centers, and they're run by the same people that run what we used to call Internet hotels, the kind of data servers like the Amazons and all the rest of this world. And then you've got the people who actually make the AI models. And the AI models, the brains of the AI live on the data centers. And that's like your OpenAI. And then they're selling them to companies, either big enterprise providers who can garnish their existing offerings with AI, or end users like me and you, or smaller companies. Is that about the size of it? Does that kind of sound about right in terms of what the AI value chain is and who all the companies are involved in this?
Neil Callanan
100%. But this is so massive now, that encompasses everything else as well. So they need energy. And so we're seeing a massive boom in energy. And people are talking about needing up to 300 gigawatts of additional energy power by 2030. That's enough to power 225 million homes for a year just for data centers. Now those things have to be built as well. You have to get people to build the data centers and build the energy infrastructure, et cetera. So construction firms are taking off as well. And so in the US in particular, it's driving a lot of the economic growth. And any slowdown in this kind of spending will be negative for growth, not necessarily turn recessionary, anything. But it would be negative for growth in the US but this goes back your point about in the end, it comes back to the end users, goes back to my point about China in a way, which is that we need people at the end to be paying for these services in order to justify these investments. When you look at the amount of money that are being spent by some of the hyperscalers in particular, which are these Internet hotels originally, as you described them, if you look at Alphabet's recent filing, forward spending commitments rose $500 billion essentially in three months. Now, future revenue growth grew, but not by anything close to that. And that goes back to the fears people have about this entire ecosystem that is sucking up so much in, so much capital at the moment that people are going, well, I don't know whether I want to have as much exposure as I could have to this. And you're starting to see that in the credit markets as well, where people are becoming much more discriminating about the deals they invest in and the price they're willing to pay. And they're also hedging a bit more this week. Core Weave's cds, which is a form of hedging against default risk that's risen to almost a record. Core Weave is one of these companies that is like a rework of the GPU world is the chips and they basically rent out to other people what they're doing. People have become much more cynical in the last few weeks about deals, partly because they know so much of this stuff is coming to the credit markets that they don't have to buy everything. The question is whether people in the AI industry, as a wider thing, have become too complacent about the idea that the credit markets will be there and be supportive of them. And that's not necessarily always going to be the case.
John Stevick
Well, I think that this is fascinating from that point of view in that there really has been a deluge. Bond issuance hasn't. I mean, we're talking about, by some measures now, the hyperscalers are the biggest issuers of corporate investment grade debt. And you're used to it being the banks. And the other point about hyperscalers is that before all this, they were basically running on their own cash generation, they were deemed as being essentially impregnable balance sheets. While it's not negative that they've started raising or not started, they've now got a lot of debt. For example, Alphabet, its latest quarter was its first negative free cash flow quarter. Ever since it listed. It's just a sort of saying that how much is out there and how these businesses are fundamentally being changed by this. And then you throw in China, maybe turning around and doing it all much, much cheaper and suddenly you're kind of like, oh, wait a minute, your earnings are going to be crushed or, sorry, the earnings that we're hoping that you get might get crushed by this. And one thing I thought was really interesting going back to the debt point is you were involved in putting together this very complicated and now famous in a sort of local way chart about how this is all being financed. And one of the big things that's I think, slightly worrying people as well is that a lot of the money seems to be coming from the people who raised the money in the first place. Almost a form of vendor financing where you've got companies that kind of make the chips, paying the people who buy the chips or who are going to rent the data centers that use the chips. Can you talk to us a bit more about that and how that's kind of pan in?
Neil Callanan
Yeah. What happened late last year was I was sitting there reading story after story about these deals where companies were doing deals with other companies in the AI universe. Nvidia has always been at the center of this, but the likes of Google and Anthropic and OpenAI were doing all these as well. And I literally couldn't keep up. And so we just had the idea that maybe we need to do a visual here and kind of show the levels of circular deals that are happening. And this became something of a bad word in the 1990s with fiber optic. And when there was a big rollout of that and lots of spending and there was vendor financing and there was capacity sharing and various other things, and then a lot of those companies went bust when the demand wasn't there at the end, having invested in all that money. Now, of course, the irony of course, is that long term the economy benefited massively from that level of spending. It's just the companies involved in Norway, so many of them ended up going bankrupt.
John Stevick
Well, that's the infrastructure story, isn't it? The railways are still here and we still have trains, but a lot of companies have built them, went bust. And same with dot com.
Neil Callanan
And that happens with Most new technologies. And again, that goes back to why investors are being somewhat skeptical at the moment about that. But these circular deals, they can create misaligned incentives around things like, are you making the decision in the best interest of the company? Are you making it in the best interest of the company that invested in you is one of your biggest customers, et cetera. And does that mean you're not devoting resources to something else when perhaps you should be? It also raises the question of whether there might be misaligned values. So, yeah, the deal is being done at, let's just say 7 billion valuation. But if that was with somebody else, might have been a 4 billion deal. You're also creating customers for you who are beholden by those contracts. And then that, like, essentially creates regulatory risk as well. But regulators may come along and go, actually, we don't like that. We're not sure whether that's the best deal for the consumer. And so all these risks are emerging that perhaps we didn't have before. But the biggest one probably of all is that these circular deals can create a false impression of demand. And you may think that these companies are generating massive revenues, but if it's all just moving around and sloshing around, then if something falls out of bed, then there could be wider implications and that could become systemic.
IBM Representative
So there's a lot of noise about AI, but time's too tight for more promises. So let's talk about results. At IBM, we work with our employees to integrate technology right into the systems they need. Now a Global workforce of 300,000 can use AI to fill their HR questions. Resolving 94% of common questions, not noise. Proof of how we can help companies get smarter by putting AI where it actually pays off, deep in the work that moves the business. Let's create smarter business.

John Stevick
The other thing I thought was interesting this week is that although Cosby's fallen out of bed, the NASDAQ took a bit of a bump, but not a big one. It so far seems to be restricted largely to the AI and the tech sector and actually plenty of other stocks are doing fine. The equal weighted S and P is doing fine. That's the S and P that's not wholly invested in the tech sector. Also, the FTSE 100 is almost back at a record high, the laggard of the global stock markets. But is this issue of how much does this spread? Or could it spread beyond the tech sector? Who else is involved in lending to these companies? And if something did break down there sort of where are the contagion vectors?
Neil Callanan
The demand means that the AI industry has had to go to pretty much every corner of the credit market and hand out the bull and kind of say give us a few quid to fund what we need going forward. And so you're seeing everything from direct lending, which is private credit, usually for infrastructure. So like just to build a data center, you're seeing investment grade. You're also seeing these neo clouds like Core Weave, who I mentioned, who are sub investment grade. Sometimes not all of them, but some of them are sub investment grade. So that's the high yield market, the junk bonds that people might know they're in the structured credit markets. These are basically taking bond payments that are due and slicing them up by risk and selling them off to people.
John Stevick
Yeah, that reminds me, didn't something like that happen in the mortgage market? What was it 20 years ago?
Neil Callanan
We haven't got to kind of of the CDO level or CDO squared level. Where I would be concerned around that. Lending in particular is around what in real estate is called speculative lending, which means something else to many people but in real estate, it's basically building the stuff before you have a tenant.
John Stevick
Yes.
Neil Callanan
And if you can get finance from that, from a bank or from a private credit lender, that says something about bubble territory, because they are taking a complete risk that you are building this thing over the course of five years and you will find somebody to occupy. And if not, or if the industry moves on and technology moves on, you can end up with a very expensive elephant at the end, which may not have much residual value for people.
John Stevick
Yeah. If you build it, they will come. It only works in the field of dreams, doesn't it?
Neil Callanan
I mean, there can be a first mover thing where you can get away with it, but if you're spending 5 billion quid, it's building a data center. I certainly would want to be more certain of that. But we are beginning to see elements of that. And we're also beginning to see terms being pushed within those deals for lending that maybe are too generous to the hyperscalers. That is the point of view of the credit markets. You're starting to hear things like after a certain amount of time, if the project is delayed, then the hyperscaler come back up. Now, if you've invested five years and spent, as I say, $5 billion in building a data center and it gets a bit delayed because let's just say something got stuck in the streets of Hormuz at the moment, that's a very big risk. Again, that's part of what's happening with the credit markets and the pullback. They're reconsidering some of the levels of risk that they're accepting at the moment.
John Stevick
From that point of view, this, arguably, as long as it's not already going too far, may be a good thing. As in maybe it gets everyone to rein end or horns a bit before it does go properly pear shaped.
Neil Callanan
Yeah. And I think it was always going to happen. And to be fair, like you look at something like the Cosby and it's still up. Many of the companies in it are still up over 100% year to date. In some cases, AI adjacent companies are up 300% for the year. So there was a natural moment for a pause anyway. And while we are seeing in terms of the Chinese evolution, is that that was always going to happen as well. And China's big advantage is it has cheap electricity, so the tokenization is cheaper. So if you're a company that's also been spending loads of money on AI and your staff, it turns out, are using it to convert Excel files into PDFs rather than actually using a much cheaper technology for that, you're going to be scouting around for cheaper prices. And so, you know, China and the Chinese LLMs become a natural kind of success story from that. And you know, that was all to be expected I think, within a certain reason. And it's just all happened very quickly and all at once as it does these days in markets. And there's a bit of panic in certain areas, particularly when it comes to retail money. You and I have spent years writing about retail money being hot money and how people can panic. And to be fair, if I had leveraged several times, I would be looking at that and going oh my God. So it's understandable in a way, but if people are sensible about how they invest, there's still major opportunities there.
John Stevick
Yeah, I mean my heart goes out to the various rookie retail investors in South Korea who are now looking at some really nasty losses. I'm hoping that they were all young enough to bounce back from it. Thanks very much for this, Neil. It's really helpful. The one other thing I would ask you about is on the the debt side. So we've flood the debt market if you like. And we have also seen a bit of equity issuance. And I suppose the other thing I'm wondering about is how much can the market take whenever we've had decades of de equitization. So companies buying back all their shares or getting bought off the market. I know we're going to get quite unusually net equity issuance quite possibly this year. What does that say to you about what might happen regarding the tightness of my overall as in just not going to be enough to go around for
Neil Callanan
all the hungry mouths I think investors will be discerning. I mean you can tell an equity story that people will follow. I mean just think within AI, how many of these companies we had heard of three years ago? Very few of any. And yeah, they may not have very much revenue, but people are willing to bet on a deal. But there's also a thing of like it can go wrong quite quickly and SpaceX is probably a good example of that. Not necessarily went wrong, but there was so much hype and now it's obviously down. Since its IPO price, which was ambitious in the first place, I looked recently and the short interest on the stock was at near 40%. People are being very bearish on the future for it and that's probably the big question for investors at the moment. SpaceX being partially an AI story with data centers in space et cetera is has that and what happened to that stock closed the IPO window for a while in that sense. Then the focus would shift back to the equity markets. Sorry, to the credit markets and the credit markets sculptor I think it was put an investor letter out recently and they talked about how credit capacity is needed at its greatest extent just as people are pulling back. And that's something you have to be a bit fearful of, I think. Now often we have taught these things and two weeks later the market has said, oh, oversold and it's popped right back up and often exceeding the previous highs, obviously. But at the moment it's definitely a moment. It's just the length that that moment takes.
John Stevick
Great. Well, look, thanks a lot Neil. I think that was really helpful. I hope the main point here was to try and explain to people what's going on and I think you've done that excellently. And obviously the market can remain excitable for longer than anyone can remain solvent, especially if you're invested in a leveraged etf. So just be careful out there. Thanks again Neil.
Neil Callanan

This episode focuses on the current state of the AI industry, exploring how the so-called "AI money machine" is funded and whether recent turmoil signals deeper issues to come. Host John Stevick and guest Neil Callanan dissect the market’s recent roller coaster, the structure of the AI value chain, the risk of circular financing, and the growing concerns about the sustainability of AI’s explosive growth—especially as competition from China accelerates and new risks emerge in both equity and credit markets.

Diverse Sources of Capital:
Parallels with 2008 Mortgage Market:
