• SpaceX's near-50% post-IPO rally has pushed its valuation into the trillions, raising concerns about overheated tech valuations.
  • The company, now the world's fifth-most valuable, has no profit forecast and reported billions in losses against revenue of $18-19 billion.
  • Analysts warn the surge may be a warning sign for tech equities, with Swissquote's Ipek Ozkardeskaya calling it a potential red flag.

SpaceX's blockbuster IPO has ignited fresh fears of a tech bubble, as the stock's meteoric rise defies fundamental metrics. The company, valued at over $2 trillion, has yet to turn a profit, stoking comparisons to the dot-com era. Shares climbed another 3.5% in premarket trading to $208.85, extending gains that have made it the world's fifth-most valuable company.

"It's a warning sign that technology valuations may have gone too far," said Ipek Ozkardeskaya, senior analyst at Swissquote. The rally, she added, is driven more by speculative fervor than by earnings prospects. SpaceX reported $18-19 billion in revenue for 2025 but deep losses, a classic high-growth scenario that investors have historically rewarded—until they don't.

Concerns are amplified by the limited float and potential index inclusion, which could fuel further volatility. Traders are bracing for automatic additions to major indices, which may trigger forced buying by passive funds. Options markets are also expected to amplify price swings, creating a feedback loop that could push valuations even higher, at least temporarily.

"The valuation is unsustainable," warned a Morningstar analyst, speaking on condition of anonymity. "Without a clear path to profitability, the risk of a sharp re-rating is significant." Critics argue that the market is pricing in years of future growth, leaving little room for error. Yet supporters see SpaceX as a once-in-a-generation play on space and AI, deserving of a premium.

The IPO has also drawn attention to broader tech valuations, with investors reallocating capital from other high-growth names. Some lawmakers have raised concerns about market stability, though no immediate regulatory action is expected.

Attempts to reach SpaceX for comment were unsuccessful. The company's next earnings report will be closely watched for signs of progress toward profitability.
