What is the central question about an AI bubble being explored at the start of the episode?
Hello, I'm Tim Bradshaw, the FT's global tech correspondent. Tectonic will be back soon with brand new episodes. But in the meantime, here's a highlight from the recent FT Weekend Festival. It's me debating what might be the most important question in the financial world right now. Is there an AI bubble and when will it burst? I spoke to Richard Kramer, a former top-rated analyst at Goldman Sachs and founder of Arate Research. And to Ophelia Brown, founder of Blossom Capital, one of London's top early-stage investors. We talked about the massive amounts of money pouring into AI right now. The real value of companies like OpenAI and Anthropic. And whether there's ever been a more exciting and confusing time to be a tech investor.
I started by asking Richard Kramer to give me a sense of the importance of tech and AI in particular to the wider financial markets.
I mean the SP right now is about sixty five trillion dollars, and about forty percent of that, about twenty seven trillion dollars, is tech. You know, we have an a vast, an unprecedented aggregation of resources at the top of the market. Uh seven of the most ten to ten most profitable companies in the world are tech companies. And next year that will likely be nine of the ten most profitable companies in the world are uh are tech companies. Uh three years ago I was here with John Thornhill and mentioned that the tech companies had about a trillion and a half dollars in sales. If you throw NVIDIA into the addition of of Google Meta, Amazon, Apple and uh And um Microsoft, uh that's three trillion dollars of sales.
Uh they generated four hundred billion dollars of cash flow. So we're talking real money, I think, at some point. Uh and that's actually going down this year to a hundred and seventy five billion, but two hundred billion of that is showing up. At NVIDIA. So uh this AI investment is kind of single handedly propping up the US economy right now. Uh seven hundred billion on CapEx, that'll be a trillion next year, and uh spending three hundred trillion in capex next year, spending about three hundred and eighty billion dollars on R and D. So that's kind of where we are in terms of scale. Okay.
And on the private markets, what's what does the Airbnb look like from your perspective on the
I think from a private markets perspective, I mean every participant considers this to be the biggest technology revolution of our lifetime and our generation. And Commensurate to the size of investment on the public market sides of trillion into CapEx, 500 billion went into two companies in the last year, OpenAI and Anthropic. And that makes up about 50% of total investment globally into AI companies. So in terms of where we stand, I think most would say that we're still relatively early in this. boom period of technical technological innovation. I think what's Fascinating is when we do a show of hands of who's got access to G BT and Claude is that to put it in perspective, I think there are one point five to one point seven billion iPhone users.
But OpenAI alone has a billion of monthly actives each month. So the distribution and the spread already amongst consumers is very high, but on the enterprise side we're still relatively high.
Yeah, and still early in in crystallizing some of that uh VC investment in the public markets as well, which we will we will kind of certainly get to. But so, I mean, uh you spend a lot of time in San Francisco in the valley. I i is there is there talk of this or fear of this being a bubble there? Or or is that just something that those of us who are outside looking in worry about?
How significant is AI‑related investment compared with the overall tech share of the S&P 500?
I think it's more of an outsider's perspective. I think I came back this week off my twentieth trip to San Francisco this year and I can certainly say that no participant there is thinking of this as a bubble. I think they really are thinking of it as a technological innovation that's going to unlock so many p pieces of our life and so many sectors that have you know especially when you come to think about the physical economy that hasn't been touched by even the software upgrade.
