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