SpaceX is about to rewrite the record books. The company confirmed plans to raise $75 billion in an initial public offering — the largest in history — and the money isn't just for rockets. It's for putting AI data centers in orbit.
A Record-Breaking Offering, by the Numbers
On June 3, SpaceX unveiled plans to sell 555.6 million shares at an initial price of $135 each, raising roughly $75 billion and valuing the company at approximately $1.77 trillion. The stock is slated to debut on the Nasdaq under the ticker SPCX on June 12.
To put that in perspective, the previous record for an IPO was Saudi Aramco's $29.4 billion debut in 2019. SpaceX is aiming to raise more than two and a half times that amount.
- Raise target: $75 billion — the biggest public offering ever
- Valuation: roughly $1.77 trillion at the offer price
- Shares: 555.6 million at $135 per share
- Ticker and exchange: SPCX on the Nasdaq
- Expected debut: June 12, 2026
Why Now? The xAI Merger Changed Everything
For years, Elon Musk insisted SpaceX would stay private until its Mars ambitions were on solid footing. What changed? In February 2026, Musk merged SpaceX with xAI, his artificial intelligence company that also includes the social platform X. That merger transformed SpaceX from a launch-and-satellites business into a combined space and AI company — and AI is now a cornerstone of its eye-watering valuation.
Notably, this is an all-primary offering. No existing shareholders are cashing out; every dollar raised flows directly into the company to fund AI computing infrastructure, Starship development, and Starlink's continued expansion.
Where the $75 Billion Goes
According to the IPO documents, the proceeds are earmarked for three priorities: scaling AI compute capacity, accelerating the Starship launch program, and growing the Starlink satellite network. The common thread is a bet that the next phase of the AI boom will be constrained by energy and infrastructure on Earth — a constraint SpaceX believes it can sidestep entirely.
Data Centers in Space: Bold Vision or Moonshot?
The most striking part of the filing is its emphasis on space-based AI data centers. Musk has argued it will eventually be cheaper to produce AI compute in orbit than on Earth, where data centers face mounting constraints on electricity, water for cooling, and land.
In space, the pitch goes, solar power is abundant and uninterrupted, cooling can radiate into the vacuum, and there are no zoning battles or grid bottlenecks. The economics depend heavily on launch costs falling — which is exactly what Starship, the fully reusable heavy-lift rocket the IPO will help fund, is designed to deliver.
This isn't purely theoretical. SpaceX is already monetizing orbital compute: its first space data center project, Colossus 1, is reportedly generating revenue at a rate of $15 billion per year for 300 megawatts of capacity — the equivalent of roughly 3,000 server racks in space.
The Skeptics' Case
Not everyone is convinced. Critics point to real engineering hurdles, including:
- Radiation and reliability: Hardware in orbit degrades faster and can't be swapped out by a technician.
- Latency and bandwidth: Moving massive AI training datasets to and from orbit is nontrivial.
- Launch dependency: The business case leans on Starship achieving rapid, low-cost reusability at scale.
- Valuation risk: At $1.77 trillion, SpaceX would be priced among the most valuable companies on Earth before proving the orbital compute model at scale.
What It Means for Investors and the AI Race
The timing is no accident. The AI infrastructure spending race has reached staggering levels — Alphabet announced plans to raise up to $80 billion in equity for AI infrastructure in the same news cycle. Capital markets are effectively funding a global buildout of compute, and SpaceX wants to position orbit as the next frontier of that buildout.
For retail investors, the SPCX listing offers the first chance to own a piece of a company that was, for two decades, one of the most coveted private holdings in venture capital. But the debut also lands amid debate over AI valuations broadly, and a $1.77 trillion price tag leaves little room for stumbles.
Markets will be watching three things closely: whether the offering prices at or above $135, how the stock trades in its first sessions on June 12, and whether SpaceX can show continued commercial traction for orbital compute beyond Colossus 1.
The Bottom Line
Whatever happens on June 12, the SpaceX IPO is a landmark moment — the biggest stock market debut in history, and a referendum on whether investors believe the future of AI infrastructure lies beyond Earth's atmosphere. If the orbital data center bet pays off, this offering may be remembered as the moment the space economy and the AI economy formally merged. If it doesn't, it will be a very expensive lesson in the limits of ambition.
