SpaceX, the rocket and satellite company founded by Elon Musk, is preparing to file paperwork with US regulators for a potential initial public offering that could become the largest in history, according to reports.
The company may submit a prospectus as early as this week, with plans to raise more than $75 billion. If achieved, the figure would surpass the record set by Saudi Aramco, which raised $29.4 billion during its 2019 stock market debut. Even earlier estimates of a $50 billion offering had already suggested a historic listing.
Ahead of a possible mid-year debut, SpaceX is expected to position itself as a platform business, with a valuation potentially ranging from $1.5 trillion to more than $1.75 trillion. Analysts say such figures reflect strong investor interest in the company’s long-term growth prospects, particularly in satellite communications.
At the center of this valuation is Starlink, SpaceX’s satellite internet service, which has driven much of the company’s recent expansion. Estimates suggest the company generated nearly $16 billion in revenue in 2025, with earnings supported largely by rapid subscriber growth in the Starlink segment. The service has become a major component of SpaceX’s business model, offering global broadband coverage and attracting both commercial and government clients.
The company’s broader vision includes ambitious projects such as space-based data centres and a proposed lunar settlement known as Moonbase Alpha. While these initiatives have captured investor attention, analysts note that they remain long-term concepts without clearly defined revenue streams at this stage.
SpaceX’s path to a public listing has become more complex following its acquisition of Musk’s artificial intelligence company xAI earlier this year. The deal, structured as an all-share transaction, valued the combined entity at about $1.25 trillion and positioned SpaceX as both a space infrastructure and AI-focused company. However, the integration of these businesses could present challenges for investors assessing risk and future performance.
Unlike many companies preparing for an IPO, SpaceX has not previously released detailed public financial statements. As a result, much of the current valuation is based on analyst estimates and secondary market data, adding a layer of uncertainty for potential investors.
If the listing proceeds as expected, it would mark a significant moment for global financial markets, highlighting the growing influence of private space companies and emerging technologies. Investors will be watching closely as more details emerge about the offering and the company’s long-term strategy.
