Can Tech Justify a Trillion-Dollar Valuation?
Wall Street Week
· · 11 min · Guests: Steve Rattner
Summary
SpaceX’s long-awaited IPO, with Anthropic and OpenAI expected behind it, was presented as a test of how far capital markets can stretch for AI-linked companies. Steve Rattner called the wave “extraordinary,” saying he had never seen companies go public at these valuations or raise this much capital at once. He framed the offering sizes as a sign that investors are valuing future cash flows, not current earnings, and that the market is betting AI will be economically transformative.
Rattner also argued that the concentration risk is real but not automatically disqualifying. The market’s heavy weighting in a small number of big tech and AI names resembles earlier speculative periods, though he said it is too soon to know whether that concentration will end badly. On SpaceX specifically, he said the launch business is excellent but too small to explain a trillion-dollar valuation on its own, implying investors must believe in future AI-related lines of business.
He warned that Elon Musk’s control creates key-man risk, even as he praised the team around him. At the same time, he said the scale of demand, revenue growth, and capital formation around AI suggests the IPO market could open the door for more venture-backed listings if these deals trade well.
Key takeaways
- Steve Rattner said the SpaceX, Anthropic and OpenAI listings are unprecedented in both valuation and capital raised.
- He argued that a trillion-dollar IPO depends on what investors believe future cash flows will be, not on current earnings.
- Rattner said SpaceX’s launch business is strong but cannot by itself justify a trillion-dollar valuation.
- He flagged key-man risk because Elon Musk holds about 85% voting control and sits at the center of the company.
- He said AI demand and revenue growth are so strong that the IPO wave could pull more private companies into public markets.
Notable quotes
“we've never had companies of this kind of valuation on the day they go public go public. We've never had this amount of capital being raised at an IPO”
“It's also, I would say, relatively concentrated as much of the stock market has been actually in big tech”
“I do believe that AI is a gamecher unlike anything I've seen in my lifetime in terms of what it the impact it could have on business”
How the episode opens
We start with the arrival of the mega IPO led by SpaceX with anthropic and open AI right behind. What does starting out with a $1 trillion market cap mean for the markets and those of us investing in them? Steven Rner is chairman and CEO of Willlet Adviserss which invests the personal and philanthropic assets of our founder and majority owner Michael Bloomberg.
Steve, this week we have had uh the IPO of SpaceX, long awaited and it's not the only one that appears to be going out at a trillion dollars or more. We also have anthropic and we have open AI. There's a lot of talk about this in the financial press.
Is it that big a deal?
Oh, yeah. This is extraordinary. Uh I've been in this business for a pretty long time.
uh back in the day when a few hundred million dollars of market cap and an IPO of $50 million was, you know, reasonable and now look where we are. Uh we've never had companies of this kind of valuation on the day they go public go public. We've never had this amount of capital being raised at an IPO.
Uh it's extraordinary and perhaps it's a natural part of the evolution of capital markets, but it is still extraordinary. It's also, I would say, relatively concentrated as much of the stock market has been actually in big tech. I mean, it's all techreated, AI related related.
Is is is that a problem potentially?
People certainly worry about it. The fact that you have such a high percentage of the stock of the stock market in a relatively small number of seven to 10 companies depending on how you count. I've seen charts showing that if you look back at the dotcom bubble, if you look back at 1929 at some of the other corrections, we there was a similar phenomenon.
