SpaceX is reportedly negotiating a secondary share sale that would rocket its valuation to $800 billion - doubling from $400 billion and making it America's most valuable private company, according to the Wall Street Journal. The eye-popping figure would vault Elon Musk's space venture past OpenAI's $500 billion mark, cementing how routine mega-valuations have become in today's private markets.
SpaceX just made private market history look routine. The company is negotiating what could be the largest secondary share sale ever, targeting an $800 billion valuation that would instantly double its worth from the $400 billion mark it hit earlier this year, according to Wall Street Journal reports.
The astronomical figure would catapult Elon Musk's rocket maker past OpenAI, currently valued at $500 billion, to claim the crown as America's most valuable private company. It's a stunning leap that reflects just how dramatically the private market landscape has shifted - companies can now achieve public-market-scale valuations while staying completely out of the public eye.
Neither SpaceX nor the WSJ reported details about the scale of the offering, leaving investors to speculate about how much liquidity the company plans to provide to employees and early backers. But the sheer size of the valuation tells the story - this isn't just about employee stock options anymore.
The move puts SpaceX in rarified air alongside the AI giants driving today's private market frenzy. OpenAI sits at that $500 billion mark, while Anthropic reportedly surged to $350 billion last month following major investments from Microsoft and Nvidia, up from just $183 billion months earlier according to industry reports.
What's striking is how these companies can now achieve valuations that rival public tech giants without any of the quarterly earnings pressure or regulatory scrutiny that comes with being listed. Secondary sales provide the perfect escape valve - giving employees and investors liquidity while keeping the companies private and focused on long-term growth.
