According to the Wall Street Journal, SpaceX is launching a secondary share sale that would value Elon Musk’s rocket maker at $800 billion — double its recent $400 billion valuation and surpassing OpenAI to claim the title of America’s most valuable private company.
SpaceX has not responded to a request for comment; the WSJ not did report on the scale of the offering.
The eye-popping figure reflects how routine mega-valuations have become within private markets. OpenAI stands at $500 billion, while Anthropic reportedly surged last month to $350 billion following major investments from Microsoft and Nvidia, up from $183 billion just months earlier.
These companies can now achieve public-market-scale valuations while remaining private, fueled by secondary sales that provide liquidity without the scrutiny of quarterly earnings reports.
SpaceX, founded in 2002, dominates commercial rocket launches and operates Starlink, its satellite internet service with over 8 million customers globally as of November.
