Private Companies Can Raise Capital at Negotiated Valuations, Public Companies Have to Raise Capital at Market Valuations
For years, Elon Musk benefited from something most corporate leaders can only dream of: easy access to practically unlimited private funding at hefty valuations determined by himself. All he had to do was build the proper narrative and convince a few large investors that his own valuation was the right one.
The SpaceX IPO fundamentally changed the process. It doesn’t mean Musk can no longer raise money. Surely, he can. But what changes is the ease, flexibility, and discretion with which he can do so.
When SpaceX was private, raising billions of dollars was relatively straightforward. Musk could approach a small group of investors, give a valuation, issue new shares, and obtain fresh capital without having to expose every detail of the transaction. He didn’t even have to convince all of them. If only a few believed his narrative, the company could raise money at an enormous valuation even while showing continuously negative operating cash flow.

That mechanism becomes much more difficult now that SPCX is publicly traded.
A public company has a market price every second of every trading day. Any new equity issuance is immediately visible. Investors know exactly how many shares are being created, at what price, and why the company needs the money. If the market suspects a company is raising capital because its existing operations cannot finance its ambitions, the stock can fall dramatically. And that creates a fundamental difference.
A private company can raise capital at a negotiated valuation. A public company has to raise capital at a market valuation.
The pressure on Musk is mounting. Every quarter he needs to deliver. Every quarter he needs to find a new narrative to prevent the stock price from collapsing.
Let’s imagine SpaceX needs $10 billion funding. When it was private, Musk could potentially raise the money from institutional investors at a valuation agreed upon with those investors. The transaction itself could even reinforce the perception that SpaceX is worth more.
As a public company, however, the calculation is completely different. If SpaceX is trading at a $1.5 trillion valuation and announces a $10 billion equity offering, investors immediately ask why the company needs the money, whether its cash flow is sufficient, and whether further dilution is coming. And if the stock falls 20% following the announcement, the company would have made its financing problem much worse than before.
This problem is particularly critical because SpaceX is a highly capital-intensive business. Its only profit comes from Starlink. But Starlink cannot finance all the other negative-cash-flow businesses by itself, mainly Starship launches and AI ambitions.
Starlink is the only cash-generating asset inside the group, and it cannot become the piggy bank for the entire group, including Tesla.
How can we forget that, earlier this year, SpaceX came to the rescue of Tesla by buying up all the unsold Cybertruck inventory, at hefty margins for Tesla, which then “beat expectations” thanks to the trick?
Would such a move be accepted by the market now that SpaceX is publicly traded?
When SpaceX was private, the boundaries between Musk’s various ventures were much less visible to the public markets. Capital could move through a relatively complicated ecosystem of private companies and investors.
Now that SPCX is public, the shareholders would question every move, knowing that they are not necessarily willing to see their company become a financing vehicle for every project associated with Elon Musk.
With the SpaceX IPO, Elon Musk played his last Ace card. Now he’s left with a handful of weak cards to try to win the game. He can still bluff that he’s got another Ace hidden in his sleeve, but it’s not clear the market will believe him this time.
Private markets gave Musk something extraordinarily valuable: financial flexibility. Public markets are now forcing him to operate without it.
But Elon Musk’s financing problems aren’t limited to the SpaceX IPO. Like any capital-intensive venture, he also has to contend with the Fed’s ill-considered policy of keeping interest rates high, supposedly to fight inflation that stems from supply shocks.
Because of the Fed, every additional percentage point of interest represents billions of dollars transferred from productive investment to debt servicing. Money that could finance AI chips, data centers, engineers, research laboratories, or new factories instead goes to creditors!
The Fed might believe it is fighting inflation, but it is in fact raising the cost of winning the AI race for companies like SpaceX.
It’s surprising that Elon Musk isn’t openly denouncing the Fed’s absurdity of keeping interest rates high, when his own companies are among those suffering most from it.
SpaceX’s recent $25 billion bond offering is a perfect illustration. The company issued five tranches, including $3.5 billion of senior notes carrying a 6.65% coupon and maturing in 2056. If the Fed’s rate were closer to 2%, the company’s borrowing costs would be at least half their current level. This bond offering is costing SpaceX somewhere around $1.5 billion a year in interest expense, that could have been slashed by half had the Fed acted quickly in reducing interest rates.
And this is precisely where the Fed’s policy becomes relevant to Musk’s financing problem.
High interest rates make borrowing far more expensive for Musk. At the same time, restrictive monetary policy makes investors more demanding about equity valuations and makes long-duration growth stories more vulnerable to changes in discount rates. They also make car loans much more expensive for potential buyers, which significantly affects Tesla sales.
Musk therefore faces a particularly uncomfortable combination: Equity financing is more visible and potentially dilutive. Debt financing is expensive. Private financing is no longer available on the same scale.
The SpaceX IPO, on top of the Fed’s mistake of keeping interest rates high, is putting significant financial stress on the “richest man in the world” as he urgently needs to find new imaginative ways to fund his highly capital-intensive ventures.
And this is without even considering the probability of a 2008-like financial crash triggered by the bursting of the AI bubble. How would Elon Musk manage to sort himself out this time in case of such financial collapse?
