SpaceX is reportedly preparing a new secondary share sale that could value the company at an astonishing $800 billion, according to a new report from The Wall Street Journal. Citing people familiar with the matter, the report says SpaceX CFO Bret Johnsen recently informed investors about the potential transaction — one that would double the company’s valuation from the $400 billion it fetched during its previous secondary sale earlier this year.
However, SpaceX has yet to comment publicly on the reported share sale or the valuation attached to it. There’s no word on the size of the sale or the investors involved at this time, and details remain unconfirmed.
If the $800 billion figure does hold, SpaceX would overtake OpenAI — valued at $500 billion as of October — to once again become the most valuable private company in the world. It would also represent a dramatic jump from July’s $212-per-share pricing that put the company at a $400 billion valuation.
For SpaceX, the rumored valuation reflects the company’s accelerating momentum across virtually every part of its business. The company continues to break annual launch records, completing more than 150 missions in 2025 alone. Starlink, meanwhile, now serves more than eight million customers across 150+ countries as SpaceX works to bridge the global connectivity gap.
SpaceX is also deep into the next phase of Starship development. Last month’s 11th flight test successfully achieved all mission objectives and formally retired the company’s Starship V2 design. The next flight — expected in early 2026 — will debut the next-generation Starship V3 architecture. Progress continues on the Starship Human Landing System as well, which will enable the first crewed lunar landing in more than 50 years.
While the company hasn’t confirmed the reported share sale, investor appetite appears to be soaring as SpaceX pushes toward its long-term goal of enabling airport-like spaceflight operations and ultimately making life multiplanetary. If the $800 billion valuation materializes, it would mark one of the largest financial milestones ever achieved by a privately held company — and signal investor confidence at a scale few companies in history have reached.
