SpaceX shares fell sharply on June 18, signaling a pause in the extraordinary investor enthusiasm that followed the company’s record-breaking stock market debut just days earlier. The decline came after a rally that briefly pushed the Elon Musk-led company into the ranks of the world’s most valuable publicly traded firms.
Shares of SpaceX dropped more than 6% during trading, extending losses from the previous session. Despite the pullback, the stock continued to trade more than 30% above its initial public offering price of $135 per share, underscoring the magnitude of its post-listing surge.

The decline wiped more than $150 billion from the company’s market value, though SpaceX remained one of the world’s largest listed companies by market capitalization. Analysts attributed the drop largely to profit-taking after an explosive debut that saw investors rush into the stock following the largest IPO in history.
SpaceX raised approximately $75 billion through its public offering before underwriters exercised an additional share option that increased total proceeds to $85.7 billion. Investor demand reportedly exceeded $250 billion during the offering process, highlighting intense interest in the company’s combination of space technology, satellite communications, and artificial intelligence ambitions.
Retail investors played a major role in the initial rally. Market data showed more than $300 million in net retail purchases during the first several trading sessions, although buying activity slowed considerably as the stock retreated.

The company’s valuation has become a central topic among investors. While supporters point to SpaceX’s leadership in commercial launches, its expanding Starlink satellite internet business, and growing AI initiatives, critics argue that expectations may have run ahead of underlying financial performance. The company reported revenue growth in 2025 but also posted a multibillion-dollar net loss as it continued investing heavily in expansion and artificial intelligence projects.
The stock’s early volatility has not surprised market observers. Analysts had warned that SpaceX’s relatively limited public float, enormous valuation, and intense retail participation could produce sharp price swings during its first weeks as a public company.
