The long-awaited initial public offering of SpaceX is finally on the horizon, and the numbers are staggering. Private market trades have already valued Elon Musk’s rocket company at over $200 billion, and with the public listing expected within the next 18 months, some analysts are whispering the T-word: trillion. For UK investors accustomed to the steady hum of FTSE 100 dividends, this is a different beast entirely. Here are three things you need to know before the hype machine goes into overdrive.
First, valuation is a game of faith, not fundamentals. SpaceX’s current private valuation already prices in a future monopoly on low-cost satellite launch and the promise of Starlink’s global broadband empire. But the company is not yet profitable. Its 2023 revenue of $8.7 billion was achieved at a net loss of $500 million. A trillion-dollar valuation implies a price-to-sales ratio of over 100 times, a mark that would make even the frothiest tech unicorn blush. UK investors, remember the dot-com bubble. Gilt yields are still above 4%, and capital has a flight instinct when euphoria meets reality.
Second, the market structure matters. SpaceX will likely list on the US Nasdaq, exposing UK investors to currency risk and foreign withholding taxes on dividends. More importantly, the float is expected to be thin. Musk and early investors hold a tight grip on equity, so the free float could be as low as 10%. That means volatility will be extreme. A 10% swing on a trillion-dollar valuation is $100 billion. Compare that to the entire market cap of BP, and you get a sense of the instability. A hard Brexit scenario for your portfolio: the pound weakens, US equities soar, and you are left trying to hedge with a screaming margin call.
Third, the regulatory backdrop is murky. The UK’s Financial Conduct Authority has yet to signal how it will treat a company that operates in a sector part commercial, part military. SpaceX’s Starshield division already contracts with the US Department of Defense. National security concerns could restrict foreign ownership or impose disclosure requirements that dampen returns. Meanwhile, the Bank of England is watching inflation like a hawk. If the Fed and the BoE diverge on interest rates, capital flows could shift away from risk assets. A trillion-dollar debut is a psychological event, but the bottom line is that markets price risk, not dreams.
For the cautious UK investor, the lesson is simple: if it seems too good to be true, it probably is. Watch the float size, the pound-dollar exchange rate, and the inflation data. And remember, in the City, we have a saying: 'A rocket to the moon can also burn up on re-entry.'
