SpaceX's $1.78tn Float: Rocket or Bubble?

SpaceX is about to make stock-market history, but analysts warn its staggering valuation may be built on little more than ambition and stardust.

On Friday, a company that lost $4.9 billion last year will attempt the largest stock-market debut in human history. SpaceX — Elon Musk's rocket, satellite and artificial intelligence empire — is set to list on the US stock exchange at a valuation of $1.78 trillion.

Investors have flooded in: the share offering has been oversubscribed by three or four times, with bids reportedly exceeding $250 billion. That enthusiasm is, depending on who you ask, either a sign of visionary confidence or a very expensive warning sign. The numbers are genuinely dizzying. SpaceX is offering at least $75 billion of shares to the public — nearly three times the previous record, set by Saudi Arabia's oil giant Aramco in 2019.

At an anticipated price of $135 per share, the company is being valued at roughly 92 times its annual sales. To put that in perspective: investors are not paying for what SpaceX has done. They are paying for what they believe Musk can do — from orbital data centres to lunar bases to, as the company itself puts it, "extending the light of consciousness to the stars." Not everyone is starstruck.

  • Why might investors bid $250 billion for shares in a company that lost money last year?
  • Michael Field advises waiting for 'a more attractive entry point.' What does this phrase mean, and do you think it is good advice?
  • SpaceX values Starlink's market at $1.6 trillion; Morningstar says $129 billion. How can two serious organisations disagree so dramatically?
  • Is it ever right for a government body like the SEC to delay or block a company's stock-market listing? Why or why not?
  • If Elon Musk becomes the world's first trillionaire, does that tell us something meaningful about the economy, or just about one unusual person?

Four Astronauts, Two Landers, One Moon

Picture this: two rival rocket companies — Blue Origin and SpaceX — both showing up at the same orbital rendezvous, trying to dock with the same NASA spacecraft. That is exactly what Artemis III is designed to test in 2027. …

A Daily Pill Doubles Survival in Deadliest Cancer

One small pill, taken every morning. That is the surprisingly simple routine which may double how long patients with the world's deadliest cancer can survive. The drug is called daraxonrasib, and results from a landmark clinical trial have stunned oncologists across the globe. Professor Naureen Starling, at London's Royal Marsden Hospital, describes it as one of the biggest breakthroughs in decades. …
