SpaceX just put a price tag on the final frontier: $135 a share.

At that price, Elon Musk’s rocket and satellite company would command a valuation of roughly $1.77 trillion, making it the largest initial public offering in history. The company plans to sell approximately 555.6 million shares, raising around $75B in a single offering. To put that in perspective, Saudi Aramco’s 2019 IPO, the previous record holder, raised about $25.6B.

The company is expected to debut on the Nasdaq under the ticker SPCX around June 11-12, 2026. A formal S-1 filing landed in May 2026, following a confidential registration back in April. The underwriter roster includes Goldman Sachs, Morgan Stanley, Bank of America, Citigroup, and JPMorgan.

How SpaceX got here

Earlier in 2026, SpaceX merged with xAI, Musk’s artificial intelligence startup. That merger bundled space infrastructure with AI capabilities under a single corporate umbrella. The combined entity now spans rocketry, satellite communications, and large-scale AI development.

The numbers in context

A $1.77T valuation would place SpaceX among the five or six most valuable companies on Earth the moment it starts trading. The $75B raise dwarfs every previous IPO by a wide margin. Even the largest tech IPOs of the past decade, think Alibaba at around $25B or Arm Holdings at roughly $5B, look modest by comparison.

What this means for investors and markets

The xAI merger adds an interesting wrinkle. Investors buying SpaceX at $135 aren’t just betting on rockets and satellites. They’re buying exposure to an AI company that competes directly with the most well-funded players in the industry.

The lead underwriter lineup includes Goldman Sachs, Morgan Stanley, and JPMorgan. With five major banks backing the deal, institutional infrastructure supports the $1.77T valuation target.
