SpaceX, which confidentially filed for an IPO in April, is planning to disclose its prospectus as soon as next week, according to people familiar with the matter, as Elon Musk’s reusable rocket company nears what’s expected to be a record share sale.
The company is aiming to kick off a roadshow to officially market the deal to investors on June 8, said the sources, who asked not to be named because of a quiet period ahead of the listing process. The filing needs to be disclosed at least 15 calendar days before the roadshow begins, but SpaceX and its advisers are aiming for a slightly earlier flip to give investors time to digest the numbers, said the people, who added that the timing may still change.
SpaceX didn’t immediately respond to a request for comment.
The IPO is expected to be the largest ever, after SpaceX merged with xAI, Musk’s artificial intelligence company, in February, in a deal that valued the combined entity at $1.25 trillion. Bloomberg reported, citing people familiar with the matter, that the company was targeting a listing size of about $70 billion to $75 billion, well over twice the size of Saudi Aramco’s record offering in 2019.
Because this much stock has never been sold in an IPO before, SpaceX’s advisers are seeking out unique channels, particularly for what they perceive to be longer-term retail holders outside the U.S., two of the people said. That includes scouting out brokers in countries like the U.K., Japan and Canada to obtain allocations for clients, one person said.
Wall Street is thirsting for IPOs after a yearslong drought, and investors are particularly excited about anything tied to the AI trade. Cerebras, an AI chipmaker, soared 68% in its debut on Thursday, closing with a market cap of about $95 billion. AI model giants OpenAI and Anthropic are also pursuing offerings as soon as this year that could push their valuations past $1 trillion.
SpaceX’s filing could hit around the time of the 12th test flight of its next-generation Starship rocket. The company previously said it was targeting May 19.
