SpaceX is reportedly in talks for a secondary sale at a valuation of $800 billion, making it the most valuable private company in America

According to the Wall Street Journal, SpaceX will launch a secondary stock sale that would value Elon Musk’s rocket maker at 800 billion dollars – Doubling its recent valuation of $400 billion and overtaking OpenAI to claim the title of America’s most valuable private company.

SpaceX did not respond to a request for comment; The Wall Street Journal did not report on the size of the offer.

This staggering number reflects how huge valuations have become routine within private markets. OpenAI is valued at $500 billion, while Anthropic last month reportedly rose to $350 billion after major investments from Microsoft and Nvidia, compared to $183 billion just months ago.

These companies can now achieve public market valuations while remaining a private company, supported by secondary sales that provide liquidity without the scrutiny of quarterly earnings reports.

SpaceX, founded in 2002, dominates commercial rocket launches and operates the Starlink satellite internet service, which had more than 8 million customers globally as of November.
