The launchpad at Cape Canaveral was eerily quiet this morning, but the real blast-off happened in the City. SpaceX, the privately held rocket company that has long defied earthly valuation models, is reportedly preparing a stock market listing that could value it at a staggering $250 billion. For the London investment community, this is not just a story of a single company’s ambition. It is a litmus test for whether the capital markets can digest the sort of speculative fever that has driven Big Tech to stratospheric multiples, while the real economy stumbles under the weight of inflation and rising gilt yields.
Make no mistake: Elon Musk is rolling the dice. A public offering at such a valuation implies that SpaceX’s future profitability is not merely assured but exponential. The company’s Starlink satellite internet division is still burning cash at an alarming rate, and the Starship programme has yet to produce a sustainable revenue stream. Yet the narrative of space colonisation has seduced venture capitalists, sovereign wealth funds, and now, potentially, the public markets. The question is whether London’s institutional investors will swallow the astronomical price-to-earnings ratios that such a valuation demands.
The timing is curious. Central banks, including the Bank of England, are still grappling with sticky inflation and the spectre of rate hikes. The FTSE 100 has been a bastion of value stocks, not growth fantasies. A SpaceX listing would be a shot across the bow of conventional asset allocation, forcing fund managers to decide whether to chase alpha in the final frontier or stick to more terrestrial income streams. I suspect many will be tempted, if only because the alternative is dull. But temptation is the enemy of fiscal discipline.
Meanwhile, the spectre of capital flight looms. American tech listings have historically drawn liquidity away from London, and a SpaceX IPO would be the biggest magnet yet. The UK’s equity markets have already lost their lustre for high-growth companies, with ARM Holdings choosing New York over London. If SpaceX chooses to float on the Nasdaq, it will be a further blow to the City’s ambitions to remain a global financial hub. But even if it lists in London, the risk is that investors overpay for a story that might take decades to deliver returns.
The bottom line is this: Musk’s gamble is a bet on the eternal optimism of markets. A bet that investors will ignore present reality for a future where humanity is a multi-planetary species. It is a bet that has paid off before, with Tesla’s dizzying rise. But Tesla had a product in high demand and a path to profitability. SpaceX’s path is far less certain. The company is a marvel of engineering but its financials remain opaque. As a financial editor, I prefer to see the books before I board the rocket.
In the meantime, London investors should brace for volatility. The space race is a narrative that will capture headlines and pound notes. But let us not forget that the City’s strength has always been its caution. We do not need to be the first to Mars. We need to be the last to a bubble.
