Less than two weeks after becoming the most valuable IPO in history, Elon Musk’s SpaceX has suffered a reality check.
The over three trading sessions, wiping out a significant chunk of the gains that followed its blockbuster stock market debut.
To put that figure in perspective, the wipeout is nearly three times the combined wealth of India’s two richest businessmen — Reliance Industries Chairman Mukesh Ambani ($88.3 billion) and Adani Group Chairman Gautam Adani ($120 billion).
The sell-off comes after investors briefly pushed SpaceX’s valuation close to $3 trillion, betting on Musk’s vision for artificial intelligence, space exploration and the future of computing.
So what changed?
The short answer is not much. And that may be exactly the problem.
When SpaceX debuted on the Nasdaq earlier this month, demand was unprecedented. Investors poured into the stock, helping it become one of the world’s most valuable companies almost overnight.
For many buyers, this was not just a bet on rockets or satellites.
It was a bet on Elon Musk.
SpaceX’s IPO arrived at a time when investors were aggressively chasing companies linked to artificial intelligence. The company had spent months positioning itself not just as a space business, but as a major AI infrastructure player through investments in data centres, computing power and AI acquisitions.
That excitement helped fuel a stunning rally.
But after the initial euphoria faded, investors began paying closer attention to the numbers.
One trigger for the sell-off was SpaceX’s announcement that it would raise fresh money through a bond offering. Ordinarily, companies raise debt all the time.
What surprised investors was that SpaceX disclosed it already had more than $100 billion in cash and cash equivalents on its balance sheet.
That immediately raised questions.
If the company has that much cash, why does it need more money?
SpaceX said the proceeds would be used for general corporate purposes and to repay existing loans. But investors interpreted the move as a sign of just how expensive Musk’s long-term ambitions have become.
Another issue is profitability.
Despite reporting revenue growth of more than 30%, SpaceX remains deeply loss-making. The company reported billions of dollars in losses as spending surged on AI infrastructure, data centres, Starship development and other expansion plans.
Investors are willing to tolerate losses when growth is extraordinary.
But after the IPO rally, many began asking whether the company’s valuation had become disconnected from its current financial reality.
At one point, SpaceX was worth more than Amazon and was challenging the world’s largest technology companies despite generating only a fraction of their revenue.
That inevitably invited scrutiny.
The decline also highlights a broader shift happening across markets.
For the past year, investors have poured money into anything associated with artificial intelligence. That enthusiasm helped create enormous valuations across the technology sector.
Now investors appear to be distinguishing between companies generating immediate AI profits and those making long-term AI bets.
SpaceX remains one of the most ambitious companies in the world. But it is also asking investors to believe in projects that may take years, if not decades, to fully pay off.
As markets become more selective, that kind of promise is facing greater scrutiny.
Even after the sell-off, SpaceX remains worth more than $2 trillion and is still trading well above its IPO price.
That suggests investors have not lost faith in Musk or the company.
What has changed is their willingness to pay almost any price for that faith.
The past three days may not signal the end of the SpaceX story. But they do suggest that after one of the most spectacular IPO rallies in market history, investors are beginning to ask a more difficult question:
How much of SpaceX’s valuation is based on today’s business, and how much is based on tomorrow’s dreams?
