The markets have a new headline to digest. Tom Mueller, the quiet engineer who built the first rocket engines for SpaceX, has broken his silence on the company’s long-anticipated initial public offering. Mueller, who famously described himself as 'employee number one,' offered few specifics on timing but made it clear that the decision rests with Elon Musk and the board. For investors, this is less a scoop and more a reminder of the peculiar nature of this particular asset.
Let us be clear. SpaceX is not a normal company. It is a privately held behemoth valued at over $200 billion, a sum that would make it one of the largest floats in history if it ever materialises. The market’s appetite for such a listing is voracious. But Mueller’s comments, in an interview with a tech publication, should be read with the scepticism that financial history demands.
We have seen this play before. The promise of a blockbuster IPO, the drip-feed of executive commentary, the subsequent letdown when valuations fail to meet the hype. Mueller, to his credit, did not fan the flames. He noted that the company’s focus remains on its mission to Mars and the Starlink satellite constellation. Both are capital-intensive endeavours that, from a balance sheet perspective, look more like a sovereign wealth fund than a conventional aerospace firm.
The bottom line is this. An IPO would be a liquidity event for employees and early backers, but it also introduces quarterly earnings pressure, shareholder activism, and the tyranny of short-termism. SpaceX has thrived on a culture of secrecy and risk-taking. Public markets demand transparency and quarterly guidance. The two are often incompatible.
From a macroeconomic standpoint, the timing is curious. Central banks are tightening, liquidity is draining, and inflation remains stubbornly above target. The FTSE 100 has been a haven for defensive stocks, not high-growth tech. A SpaceX listing would absorb a significant amount of capital, potentially crowding out other sectors. Gilt yields have been volatile, and a jumbo IPO could exacerbate that.
Capital flight is another consideration. UK investors, starved of high-growth opportunities, would likely pile in. But the premium demanded by private markets for SpaceX shares has already been steep. In secondary markets, shares have traded at valuations that make little sense by traditional metrics. Price-to-sales ratios are unheard of. The only justification is the narrative of Elon Musk himself.
Mueller also hinted at the possibility of a direct listing, bypassing the traditional underwriting process. This would be a direct hit to investment banks, who thrive on fees. But it also reduces the regulatory scrutiny that comes with a full IPO. The FCA will be watching closely. Market efficiency demands full disclosure, but SpaceX has built its brand on secrecy.
My own view is that the market will have to wait. Musk is not one to cede control easily. He has seen what happens when founders lose grip on their companies. The Twitter acquisition was a cautionary tale. SpaceX remains his jewel. An IPO would be a concession to the inevitable, but he will delay it as long as possible.
For now, investors should treat any announcement with caution. The hype is priced in. The reality is that SpaceX is a remarkable engineering achievement but a questionable financial asset at these valuations. The prudent money stays on the sidelines. The speculative money will chase the dream. I know which side I prefer.
