Elon Musk’s SpaceX is looking to raise $75bn (£55bn) from its blockbuster stock market listing next week as the rocket company aims for the largest initial public offering ever.
If the stock market launch – primed for 12 June – goes as planned, founder Musk, the world’s wealthiest person, could make history as the first trillionaire.
The rocket, satellite and artificial intelligence company, formally known as Space Exploration Technologies Corp, said in a filing on Wednesday that it would sell 555.6m shares at $135 a piece.
That would give SpaceX, which is loss-making, a market value of $1.77tn. Only six companies in the blue chip S&P 500 stock market index are worth more, with the US semiconductor company Nvidia topping the list at $5.2tn. The previous record for an IPO is the oil company Saudi Aramco, which floated in 2019 at a price of $1.7tn and raised $25.6bn.
Musk is not selling any of his shares in the SpaceX offering and would retain 82.4% of the voting power in the company.
Forbes values Musk’s net worth at $825bn, and his stake in SpaceX at $542bn. The South African-born billionaire also leads Tesla, the electric carmaker, as well as the social media platform X. Forbes said in April a SpaceX float would “all but guarantee his net worth rising above $1tn”.
SpaceX is expected to have a hefty weighting in the S&P 500 due to its sheer size, which means most people with investment accounts or pension pots will be exposed to its stock market performance as investors in the company.
SpaceX confidentially filed to go public in April. Founded in 2002, SpaceX has been central to Musk’s ambition of building a “self-sufficient city on Mars”. Since its inception, the company has been the recipient of lucrative aerospace contracts. Nasa, for example, depends on SpaceX rockets for most of its launches.
SpaceX has also joined competitors such as Anthropic and OpenAI in the race to scale up AI technology. The company acquired Musk’s xAI in a move to build out solar-powered infrastructure that could meet the energy demands of this AI boom era.
Anthropic, known for its AI chatbot Claude, filed paperwork this week to go public. OpenAI, the company behind ChatGPT, is expected to follow suit soon. Alphabet, the owner of Google, moved to raise $80bn in equity this week to fund its vast AI infrastructure investments.
The wave of splashy IPOs and fundraising has widely been interpreted as an attempt to generate capital that will fund datacentres powering the AI technology. SpaceX, which houses Musk’s xAI company, wants to develop datacentres in space and expects to start launching “orbital compute” by 2028.
The sprawling SpaceX business will be split into three parts: the rocket-launching unit; the Starlink satellite broadband arm; and the AI company that includes X, the social media platform formerly known as Twitter. The entire business is loss-making although the Starlink section is profitable. Despite its lofty valuation, the SpaceX business lost $4.9bn in 2025 on revenues of $18.7bn. But revenue is growing and rose by a third on the previous year.
A roadshow for SpaceX’s IPO is expected to start on Thursday, during which bankers helping the deal kick off will pitch the company to investors. SpaceX is viewed by some market watchers as a means of investing in Musk’s entrepreneurial flair and tapping into the AI boom.
In the longer term, some investors hope Musk could bring together Tesla – the electric carmaker in which he owns an 11% stake – and SpaceX in a mega-merger, giving the markets a one-stop shop for investing in the tycoon.
“Musk wants to own and control more of the AI ecosystem and step by step the holy grail could be combining SpaceX and Tesla in some way to give the connected tissue between both disruptive tech stalwarts looking to lead the AI revolution,” said Dan Ives, an analyst at the US financial services firm Wedbush Securities.
The JP Morgan Chase boss, Jamie Dimon, is reportedly planning to discuss the IPO with thousands of the bank’s high net worth clients this week, according to Bloomberg.
Dimon will reportedly host a “live interactive discussion” on Thursday from JP Morgan’s headquarters, joined by Mary Callahan Erdoes, the boss of the bank’s asset and wealth management division, as well as two SpaceX executives: its president, Gwynne Shotwell, and the chief financial officer, Bret Johnsen.
Space X’s listing represents a huge money-making opportunity for bankers. Last month, Goldman Sachs was selected as the lead bank for the IPO, alongside Morgan Stanley. JP Morgan, Bank of America and Citigroup are also among the 23 banks working on the listing.
