Elon Musk’s SpaceX is reportedly targeting a $1.75 trillion valuation in what would be the largest initial public offering in history, a move that has UK institutional investors circling with intent. The figure, more than three times the current market capitalisation of Tesla, reflects the market’s insatiable appetite for space-based assets and the promise of Starlink’s cash flows.
But let us not get carried away by the rocket fuel. A $1.75tn price tag would make SpaceX worth more than all but a handful of global companies. For context, that is larger than the entire UK gilt market. The valuation is being pitched on the back of Starlink’s growing subscriber base and the long-term potential of interplanetary travel, but the near-term economics remain murky. Starlink may be profitable on a unit basis, but the capital expenditure required to sustain its satellite constellation is immense.
UK pension funds, starved of yield in a low-growth environment, are understandably eyeing a slice. But there is a spectre of capital flight here. If British institutions pile into this US giant, they are effectively exporting domestic savings to fund Musk’s ambitions. The government’s Mansion House reforms, designed to channel pension cash into UK equities, will be put to the test.
The IPO’s size also raises questions about market absorption. A $10 billion raise would require significant liquidity, and with central bank tightening still draining markets, the timing is precarious. The Bank of England’s rate path remains clouded, and a misstep could see gilt yields spike, making fixed income more attractive relative to high-beta tech stocks.
Still, the allure of space is undeniable. SpaceX’s dominance in launch services and its monopoly on crewed missions to the ISS give it an unassailable moat. The question is whether the valuation already prices in a decade of perfection. For UK investors, this is a bet on Musk’s execution and the regulatory environment for Low Earth Orbit. The FCA will be watching closely, but don’t expect them to block it. The City loves a big fee.
In the end, this is a classic tale of fiscal discipline versus market euphoria. The prudent saver might wait for the launch window, but the speculators are already strapped in.
