SpaceX eyes $800 billion valuation in secondary share sale as Musk signals possible IPO

Elon Musk’s SpaceX is launching a secondary share sale that could value the company at $800 billion, surpassing OpenAI as the most valuable private company in the U.S., according to The Wall Street Journal. CFO Bret Johnsen informed investors of the sale, while executives are also weighing a potential IPO in 2026. The $800 billion valuation represents a dramatic jump from previous transactions, doubling a recent $400 billion secondary sale and more than tripling the $250 billion valuation from November 2024. The surge reflects SpaceX’s dominance in reusable rockets, satellite infrastructure, and launch services, outperforming rivals like Blue Origin. A major driver is Starlink, the company’s global satellite internet business, which provides a steady revenue stream. Any future IPO would likely include Starlink, giving public investors exposure to both space transportation and global connectivity. Musk has expressed hesitation about public markets, citing lawsuits and operational challenges, but has not ruled out a listing. For now, the secondary sale highlights investor confidence in SpaceX’s growth and long-term potential, though whether this momentum leads to an IPO remains uncertain.
