Space Exploration Technologies, widely known as SpaceX, has filed for an initial public offering in what could be the largest share listing ever.
The rocket and satellite company, founded and led by Tesla (TSLA) Chief Executive Elon Musk, seeks to list its class A shares on the Nasdaq under the ticker SPCX, according to a preliminary prospectus filed with the US Securities and Exchange Commission on Wednesday.
The filing did not provide details about a potential IPO size or the expected price range, but The Wall Street Journal reported that SpaceX could raise $80 billion or more as soon as next month. that would eclipse Saudi Aramco's blockbuster IPO in 2019.
SpaceX intends to have a dual-class stock structure, with each class A share entitling the holder to a single vote. Class B shareholders will get 10 votes per share. Musk already owns 93.6% of class B shares, the filing showed.
SpaceX estimates its quantifiable total addressable market at $28.5 trillion across AI-related markets, space-enabled solutions and connectivity services, according to the filing.
The company, which operates satellite internet service provider Starlink, recently acquired artificial intelligence startup xAI.
The filing showed SpaceX reported a net loss of $1.69 per share in 2025, compared with a breakeven point in 2024. Revenue increased 33% to $18.67 billion in 2025.
AI capital expenditures totaled $12.73 billion in 2025 and $7.72 billion in the first quarter of 2026.
"The company looks to own more of the physical AI compute stack over time to lower the cost-per-token input for enterprise AI customers," Wedbush Securities said in a note.
SpaceX plans to sell a portion of shares directly to retail investors through platforms including Charles Schwab (SCHW), E*TRADE by Morgan Stanley (MS) and Robinhood Markets' (HOOD) Robinhood Financial, according to the filing.
Tesla and SpaceX are expected to merge next year, Wedbush analysts including Dan Ives wrote in the Wednesday note.
"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," Ives said.
