The financial world is watching with a mixture of awe and apprehension as SpaceX, the private rocket company founded by Elon Musk, experiences a dramatic surge in its stock market valuation. City analysts are sounding alarms, calling this perhaps Musk’s most reckless bet yet. The surge, driven by retail investor frenzy and speculative trading, has pushed SpaceX’s implied valuation to dizzying heights, dwarfing established aerospace giants like Boeing and Lockheed Martin.
Let’s be clear: SpaceX is not a publicly traded company. The stock surge refers to trading on secondary markets, where shares change hands between private investors. These trades are thinly regulated and opaque, a perfect breeding ground for irrational exuberance. The implied valuation, now hovering around $150 billion, is based on a handful of transactions, not a robust public market.
Why the alarm? For one, SpaceX’s revenue streams are still nascent. While its Starlink satellite internet service shows promise, it is years away from profitability. The company’s core business, launching rockets and ferrying astronauts, is capital-intensive and faces stiff competition from Amazon’s Project Kuiper, OneWeb, and traditional players. Moreover, Musk’s tendency to make audacious promises that defy conventional timelines is legendary. The Starship project, intended for Mars missions, is still grounded after a series of test failures. Markets, however, seem to be pricing in flawless execution.
There is a whiff of Tulip Mania about this. The same retail investors who chased GameStop and AMC are now piling into SpaceX, pushing its valuation beyond what any fundamental analysis would justify. Analysts point to the lack of liquidity in these shares: a sudden wave of selling could trigger a catastrophic collapse. The parallels to the 2021 SPAC boom are uncanny. Remember when electric vehicle startups with no revenue were valued in the billions?
But there is a deeper concern: capital flight from productive assets into speculative bubbles. While the Bank of England raises rates to curb inflation, investors are chasing moonshots. This misallocation of capital could have real consequences. If the SpaceX bubble bursts, it will not be confined to Silicon Valley. Pension funds and institutional investors have exposure through private equity funds that hold SpaceX shares. A sharp correction could ripple through financial markets.
Musk himself fuels the fire. His recent tweet, “SpaceX is now worth more than Lockheed + Boeing combined. Onwards to Mars!” is typical of his style: confident, dismissive of risk, and deliberately provocative. For a man who once joked about taking Tesla private at $420 a share and faced SEC scrutiny, this is par for the course. But for investors, it is a red flag.
Let’s not forget the opportunity cost. The same capital could be deployed in government bonds yielding 4.5% with virtually no risk. Instead, it is poured into a company whose success hinges on Musk’s whims and the laws of physics. Fiscal responsibility is being thrown out of the window.
Am I saying SpaceX will fail? No. The company has achieved remarkable technical feats: reusable rockets, the first private company to send astronauts to the ISS. But the current valuation implies that it will not only dominate space launch and satellite internet but also colonise Mars. That is a lot of assumptions. Market efficiency suggests that such extreme valuations are not sustainable.
The bottom line: this surge is a bet on Musk’s myth, not on a sound business. History judges such bets harshly. The City would do well to remember the lessons of the South Sea Bubble. The music may be playing, but the floor is getting crowded.
