SpaceX is preparing for a public listing that could reshape capital market history, though debates over its valuation rationale and business integration logic remain key uncertainties. According to earlier reports, SpaceX aims to raise up to $50 billion through an IPO, targeting a valuation exceeding $1.75 trillion. If successful, this would surpass Saudi Aramco’s $29.4 billion record set in 2019, making it the largest IPO ever. The space company, led by Elon Musk, could go public as early as June this year.
However, SpaceX’s recent all-stock acquisition of xAI has unsettled some investors. xAI is burning approximately $1 billion monthly on AI infrastructure, raising concerns that this cash drain may dilute the appeal of SpaceX’s core business—particularly its satellite internet service, Starlink. Whether public market investors will accept such a high valuation remains unclear.
SpaceX has reportedly selected several major Wall Street banks to assist with IPO preparations, including filing confidential documents with the U.S. Securities and Exchange Commission (SEC) as early as March. This would initiate a typical two-to-three-month review process. Following SEC approval, SpaceX will publicly file its prospectus, revealing its financials for the first time. A 15-day public comment period will follow before the company begins roadshows to pitch shares to institutional investors and set a price range. Trading is expected to begin shortly after final pricing.
Underwriters including Bank of America, Citigroup, Goldman Sachs, JPMorgan, and Morgan Stanley are confirmed participants, though their specific roles have not been finalized.
Starlink serves as the core justification for SpaceX’s valuation. The global satellite broadband service is the company’s primary cash flow generator, with growing user numbers, dominance in commercial rocket launches, and ongoing direct-to-cell network development creating a unique business profile. As one analyst noted, “Starlink’s user growth, launch market leadership, and cellular ambitions form a combination unmatched in public markets.”
Additional factors supporting the valuation include SpaceX’s leadership in commercial spaceflight, billions in government contracts, and deep ties to defense and telecommunications sectors.
The acquisition of xAI, however, introduces controversy. Critics argue that integrating a high-cash-burn AI venture could lead to SpaceX being valued as a loosely structured conglomerate, potentially below expectations. Musk defends the move as “vertical integration innovation,” suggesting synergies between rockets, space internet, AI, and social media could advance opportunities like space-based data centers.
Prior to the xAI deal, Musk held less than half of SpaceX’s shares, with external investors including Founders Fund, Fidelity, and Alphabet. Post-acquisition, his stake remains unclear. Reports indicate SpaceX may adopt a dual-class share structure, allowing insiders—likely including Musk—to retain near-total control after the IPO. While this may not deter investors confident in Musk’s track record, it could limit external shareholder influence if issues arise.
Musk’s personal reputation may also help justify the valuation. Tesla’s stock surged roughly 3000% over the past decade, rewarding many investors. For some, this history serves as a powerful endorsement.
The IPO is also expected to offer retail investors access through platforms like Robinhood and SoFi, though allocation for individual investors in high-demand IPOs is typically limited.
