SpaceX, the aerospace manufacturer led by Elon Musk, has initiated an insider share sale that values the company at approximately $800 billion, positioning it as the world's most valuable private company.
The transaction allows new and existing investors, along with the company itself, to purchase up to $2.56 billion in shares from eligible shareholders at $421 per share.
This price nearly doubles the previous internal share valuation.
In a letter to employees dated December 12, SpaceX Chief Financial Officer Bret Johnsen outlined preparations for a possible initial public offering in 2026.
Johnsen noted that the timing, occurrence, and valuation of any IPO remain uncertain, depending on execution and market conditions.
A successful public listing could raise significant capital and rank among the largest initial public offerings globally.
The move comes as the IPO market shows signs of resurgence in 2025 following a multi-year slowdown.
Proceeds from a potential offering would support accelerated development of the Starship rocket program, deployment of artificial intelligence data centers in space, establishment of a lunar base referred to as Moonbase Alpha, and missions to Mars.
The rapid growth of SpaceX's Starlink satellite internet service, including plans for direct-to-mobile capabilities, has driven the company's expansion and investor interest.
SpaceX has secured substantial funding from investors over the years, with Musk retaining the largest individual stake.
The company maintains close ties with NASA and the Pentagon, playing a key role in space exploration and national security initiatives.
SpaceX did not immediately respond to requests for comment on the share sale and IPO preparations.
