SpaceX said Wednesday it plans to raise up to $75 billion in an IPO this month that would value the company at $1.77 trillion and could make Elon Musk the world's first trillionaire.
The company said it will sell 555.6 million shares at $135 a piece.
SpaceX's amended prospectus says Musk owns 5.22 billion Class B shares that carry 10 votes each and that his holdings would give him 82.4% of the company's voting power.
The IPO document says proceeds would be used to help put men on the moon again and perhaps even Mars, and it calls for building "a permanent human colony" on the red planet with "at least one million inhabitants" as existential threats loom that could consign man to "the same fate as the dinosaurs."
Musk's net worth is valued at $826 billion and his stake in SpaceX at $542 billion.
The estimated proceeds from the SpaceX IPO would top the $26 billion raised by oil giant Saudi Aramco in 2019.
Only six companies in the S&P 500 are currently worth more than the offering's implied valuation, with Nvidia tops at $5.2 trillion.
Anthropic submitted a confidential filing with the U.S. Securities and Exchange Commission this week, and OpenAI has not yet reported filing initial SEC paperwork, though an IPO from the ChatGPT maker is widely expected.
