SpaceX’s public-market debut delivered the spectacle investors expected. Yet its first trade also exposed a deeper puzzle: Wall Street celebrated one space company while selling almost every other space stock, and investors still cannot agree on what kind of business they have just valued above $2 trillion.
SpaceX opened at $150 per share, surging approximately 11% from its $135 offering price. It soon rocketed to $174 a share which valued the company at roughly $2.3 trillion, immediately placing it among the world’s most valuable publicly traded companies.
The opening also closely matched the price previously indicated by unofficial pre-IPO markets. Those markets had suggested SpaceX could begin trading near $175, making their earlier bullish prediction surprisingly accurate but no longer particularly relevant after the official debut.
Musk’s Trillion-Dollar Moment
SpaceX’s opening surge appears to have pushed Elon Musk’s personal fortune above $1 trillion on paper, making him the first person in history to reach the milestone.
The number is difficult to comprehend. One trillion seconds is equal to approximately 31,700 years. Someone spending $1 million every day would need roughly 2,740 years to spend $1 trillion.
Even after selling some shares in the IPO, Musk retains a substantial economic interest in SpaceX and overwhelming voting control. At the opening valuation, his SpaceX stake alone is worth hundreds of billions of dollars, while his holdings in Tesla and other businesses push his estimated total wealth beyond the trillion-dollar threshold.
However, the most important development for ordinary investors may not be Musk’s wealth. It may be how the market has chosen to classify SpaceX.
SpaceX is officially considered an industrial stock, rather than a communications or technology company. That distinction could influence how analysts, sector funds and institutional investors value the business.
Technology and communications companies are frequently valued using subscriber growth, recurring revenue and future addressable markets. Industrial companies are more commonly judged on order backlogs, capital expenditure, operating margins and returns on invested capital.
SpaceX contains elements of both. Starlink resembles a communications platform, xAI gives the company exposure to artificial intelligence, while its rockets, spacecraft and government contracts resemble a capital-intensive aerospace manufacturer.
At its $174 opening price, SpaceX traded at more than 120 times its 2025 revenue. The market is therefore assigning a technology-style valuation to a company officially placed in the industrial sector. Whether that combination can survive future earnings reports may become one of the stock’s defining questions.
A Historic Debut Exposes A Divided Market
Demand for the IPO was extraordinary. Total orders reportedly exceeded $250 billion, while retail investors alone submitted more than $100 billion in orders.
Major asset managers requested billions of dollars in shares. Middle Eastern sovereign wealth funds, including funds connected to Saudi Arabia and Kuwait, also sought substantial allocations. For these investors, SpaceX offers exposure not only to rockets and satellites, but also to communications infrastructure, defense contracts and artificial intelligence.
Pension funds have been far less enthusiastic.
Several large pension investors resisted participating directly because of SpaceX’s valuation, corporate governance and Musk’s continued voting control. Their opposition creates an unusual situation: pension funds may refuse to buy the IPO voluntarily, only to become indirect shareholders later if SpaceX enters major indexes and passive funds are forced to purchase the stock.
The broader market’s reaction also revealed signs that the SpaceX listing may have marked a short-term peak for the space-investment theme.
Shortly after SpaceX began trading, several prominent space stocks fell roughly 8% to 11%. The decline resembled a classic “buy the rumor, sell the news” event. Investors who had purchased smaller space companies as substitutes for SpaceX appeared to take profits once the real company became publicly available.
At the same time, semiconductor shares regained investors’ attention. While space-related companies fell sharply, the major semiconductor ETF moved higher in early trading. The contrasting performance suggested that some speculative capital was already rotating away from the space theme and returning to AI-chip companies with more visible revenue and earnings.
Stars Ahead Or A Severe Bubble?
The bullish case for SpaceX remains powerful.
The company dominates commercial rocket launches, operates the rapidly expanding Starlink satellite network and holds strategically important relationships with the U.S. government. Starship could dramatically reduce launch costs, while orbital data centers could eventually connect SpaceX’s launch capabilities with the growing demand for artificial-intelligence computing.
The IPO also gives SpaceX an additional $75 billion to fund those ambitions. Few companies possess a comparable combination of technology, capital, government support and willingness to pursue projects that may take decades to become profitable.
However, the current valuation assumes that several difficult projects will succeed simultaneously.
SpaceX generated approximately $18.7 billion in revenue during 2025, but recorded a net loss of nearly $5 billion. Its AI operations require enormous capital expenditure, while Starship and orbital computing remain technologically and commercially uncertain.
Morningstar estimates the shares are worth only $63, almost 64% below the opening price. Valuation professor Aswath Damodaran places the company’s value near $1.2 trillion, roughly half its opening market capitalization. A more bearish scenario values the company at approximately $500 billion, implying a decline of nearly 80%.
None of those estimates guarantees that the stock will fall immediately. Limited publicly available shares, index-related buying and intense retail demand could keep the price elevated for months.
But after the excitement of the opening trade fades, SpaceX must begin proving that its many ambitious businesses can generate enough cash flow to justify an industrial company trading at a technology valuation.
The company may genuinely be building humanity’s future among the stars. The harder question for investors is how much of that future has already been included in today’s price.
