SpaceX has taken the wraps off its IPO filing, opening the books of the company that has already revolutionised rocket technology, with even larger ambitions to colonise Mars and build AI data centres in space.
The listing is poised to become the first trillion-dollar US market debut and could set the stage for a number of monumental IPOs in the coming months, among them potentially technology giants OpenAI and Anthropic.
The sale would immediately cement SpaceX as one of the world's most valuable publicly traded companies, the second in Elon Musk's sprawling business empire to surpass $1 trillion in market value.
SpaceX has grown into the world's largest space business since its founding in 2002 by launching thousands of Starlink internet satellites. Its pioneering use of reusable rockets has transformed the economics of space, forcing competitors like Jeff Bezos' Blue Origin to play catch-up.
While SpaceX made its name by building rockets and launching satellites into space, most of its $18.67 billion in revenue last year came from its Starlink satellite internet business and much of its future growth hinges on artificial intelligence-related businesses. Its nascent xAI unit still loses money, according to the filing.
A successful sale could value the company at a record-setting $1.75 trillion, putting its founder on track to become the first trillionaire in history, validating years of defying accepted logic through the development of rockets that can land and be flown again.
The company's regulatory disclosure comes during a critical week for the rocket maker, which is preparing to launch a test flight of its next-generation Starship rocket.
Musk's plans for lunar and Mars missions and to expand its Starlink satellite internet business depend on the new rocket.
The test launch, originally scheduled for Tuesday, is now expected later this week.
The board has given Musk control over the company, but ties much of his compensation to audacious targets of establishing a permanent human colony on Mars and building space data centres with compute capacity powered by the equivalent of 100 terawatts, or 100,000 one-gigawatt nuclear reactors, Reuters previously reported.
SpaceX is aiming to list its shares as early as June 12, with a roadshow launch targeted for June 4 and the share sale expected as early as June 11, Reuters reported last week.
'Halo effect'
Musk's CEO celebrity persona may matter more to some investors than SpaceX's underlying business fundamentals, analysts and academics said, because there are no other comparable companies against which to benchmark its valuation.
The company said it was targeting a potential total market of $28.5 trillion across its businesses, with a majority of that possible revenue tied to AI.
The $1.75 trillion valuation target, if achieved, would eclipse Saudi Aramco's 2019 offering, which set a record as the world's biggest IPO when it debuted on Riyadh's exchange at $1.7 trillion.
SpaceX had planned to try to raise more than $75 billion in the offering, Reuters previously reported.
The scale of the offering has drawn attention to the increasingly interconnected structure of Musk's business empire, often dubbed the "Muskonomy," which includes the leading electric vehicle company Tesla, as well as his businesses in artificial intelligence and brain-chip implants.
SpaceX merged with Musk's artificial intelligence startup xAI in a deal that valued the rocket company at $1 trillion and the developer of the Grok chatbot at $250 billion.
Concerns about Musk's ability to juggle multiple companies with combined market values exceeding trillions could weigh on investor sentiment, analysts said.
IPO push and pull
High-profile AI firms, including OpenAI and Anthropic, are also exploring potential public listings later in 2026. Demand for SpaceX’s listing could influence the timing and appetite for other upcoming IPOs.
SpaceX plans to earmark a significant portion of shares for retail investors and will host about 1,500 of them at an event in June following the IPO roadshow launch, Reuters reported in April.
The company is expected to list on the Nasdaq under the ticker symbol 'SPCX.' Goldman Sachs, Morgan Stanley, Bank of America, Citigroup and J.P. Morgan are the bookrunners.
