Psupportive investors concerned about the trend for companies to do this grow into giants outside the public markets, a new problem could soon arise with these megacaps.
Companies like SpaceX, Stripe, OpenAI, and many more have created hundreds of billions of dollars—perhaps more than $1 trillion in SpaceX’s case—in shareholder value without deigning to raise money the old-fashioned way through an IPO and the public markets.
Employees have become millionaires and some venture capital funds have made fortunes. But the average investor has missed out on such wealth creation over the past decade.
Online platforms and software companies discovered that in the age of cloud computing, they needed little upfront capital to support their growth. Very different from the past, when growing companies had to build factories or dig mines.
But even the companies that had to spend big – like SpaceX and OpenAI – have been able to tap huge amounts of private money. This way they could continue to expand without the burden of public scrutiny or a volatile stock price.
Good for them, although I’ve thought before about the threat this poses to public stock markets as the engine for the democratic wealth creation we’ve enjoyed for a hundred years.
Whale sharks
Some of today’s largest and best-known AI-related startups are expected to finally go public in the US this year. thanks to the voracious capital requirements of AI infrastructure rollout.
But if you’re a passive investor in the S&P 500, you might wish this weren’t the case.
As venture capitalist Tomasz Tunguz points out, these companies grew so big before going public that it’s not clear how the market will find the money to take a stake:
Tunguz notes:
At standard float rates, these three companies would need to raise $432 billion to $576 billion in a single quarter from the public markets.
From 2016 to 2025, the entire U.S. IPO market raised $469 billion.
It’s like throwing a boulder into a pond. Standard floats are impossible, so these companies will debut with small floats, probably 3-8%.
It is a theme that will be discussed during the Financial timeswhere Craig Coben highlights how Nasdaq is proposing to adjust its listing rules to welcome these behemoths.
Broken houses
The problem is, as Joseph Stalin noted, “Quantity has a quality all its own.”
These companies are so ridiculously large that certain uncomfortable realities of the stock market listing process – such as being ahead of index funds that are required to buy the shares – become almost existential threats at this scale.
You’ll have to read Coben’s full piece for the details, but here’s his sobering conclusion:
In short, [Nasdaq’s] The proposed changes will allow founders and management to float fewer shares, maintain tighter control, and still benefit from the valuation population through rapid benchmark inclusion.
In the meantime, [index fund] holders are faced with the other side of the trade – forced to buy into a low free float after the market has already favored them.
Nasdaq may describe the consultation as modernization, but in practice it appears to be the blueprint for a new kind of market conquest.
I don’t feel like I’m qualified to judge what exactly will happen if a $1 trillion company wants to become the sixth largest company in the public markets overnight.
But I know the process wasn’t meant to work this way.
Supermassive
Some people are also concerned that all the potential value has already been created by these companies because they went public so late. Therefore, public market investors buying into it now are doing the same thing as securing it shares on Lastminute.com on the eve of the Dotcom crash.
That is clearly tautologically true. If SpaceX had been at, say, $1 billion 20 years ago, US small-cap index returns would have been in much better shape over the past few decades.
But it’s also true that the largest companies in the US will likely be larger than $10 trillion by 2040. There may still be room for even more multi-bagging.
Especially if, you know, AI ends up taking over all the work of every other company on the market…
Have a nice weekend.
