SpaceX is moving to file an initial public offering prospectus that could see the company raise upwards of $75 billion by June 2026. This is not just another high-profile market debut; it is a calculated attempt to secure the largest capital injection in the history of the stock market, eclipsing Saudi Aramco’s record-setting 2019 listing. The filing, expected to hit regulatory desks within the next fortnight, seeks to anchor the company at a staggering $1.75 trillion valuation. While the public narrative centers on Starship and Mars, the quiet reality of this IPO is a fundamental pivot from being a launch provider to becoming the world’s first space-based cloud computing power.
The numbers alone are enough to make a seasoned analyst blink. In 2025, the company generated $16 billion in revenue with $7.5 billion in EBITDA. By the end of 2026, projections suggest revenue could hit $24 billion. This growth is almost entirely propelled by Starlink, which has effectively transformed from a fringe experimental ISP into a global utility serving over 9 million subscribers. But the $1.75 trillion target suggests investors are being asked to buy into something far larger than just faster internet for rural homes.
The xAI merger and the heat problem
In February 2026, a structural shift occurred that few in the general public fully grasped. SpaceX absorbed Musk’s artificial intelligence venture, xAI, in a move that valued the combined entity at $1.25 trillion. This was not merely a consolidation of assets. It was a technical necessity for the next stage of the business.
Terrestrial data centers are currently hitting a wall. They consume vast amounts of water for cooling and place immense strain on power grids. By moving massive compute workloads into orbit, SpaceX intends to solve two of the biggest overhead costs in AI development: electricity and cooling. In the vacuum of space, satellites can use giant radiators to shed heat into the void while drawing constant, unmitigated power from the sun. The goal is to build orbital data centers where Starlink’s mesh network acts as the data bus for xAI’s large language models. This IPO is the war chest required to build that infrastructure.
The Starship bottleneck
For this $1.75 trillion valuation to hold water, the Starship program must transition from experimental flights to a reliable cargo train. In 2025, SpaceX achieved 122 successful launches, but most were the workhorse Falcon 9. To deploy the Starlink V3 satellites—the hardware capable of supporting orbital data centers—the company needs Starship’s massive payload capacity.
The risk here is one of cadence. If Starship development stalls due to the "harmonic resonance" issues seen in earlier 2025 flights, the entire revenue model for the orbital cloud begins to fray. The company is betting $75 billion that they can turn the most powerful rocket ever built into a routine delivery vehicle by 2027.
Why now and who gets in
The timing of the June 2026 window is a mix of tactical financial planning and characteristic Musk flair. Advisors suggest the goal is to hit the market while the xAI integration is still fresh and the revenue growth from Starlink’s maritime and aviation sectors is at its steepest. Retail investors are expected to be given a significant slice of the pie, with reports suggesting up to 20% of the offering could be earmarked for individual buyers.
However, the "central case" for the IPO remains the appetite of institutional heavyweights. Long-term backers like Baillie Gifford and Scottish Mortgage have already seen their positions grow to represent massive portions of their portfolios. These firms are looking for a liquidity event, but they are also looking for a sign that SpaceX can transcend the volatility of the aerospace sector.
There is a gritty reality to this valuation that many are ignoring. At $1.75 trillion, SpaceX would be trading at roughly 72 times its projected 2026 revenue. For context, traditional defense contractors like Lockheed Martin or Boeing typically trade at multiples closer to 1.5 or 2. This is not a defense stock; it is a technology stock that happens to own the sky. If the market experiences a bout of volatility or if the Federal Reserve shifts its stance on interest rates, that 72x multiple becomes a very dangerous place to be.
The 2026 IPO is the moment SpaceX stops being an aspirational venture and starts being a scrutinized public utility. The transition will be painful, demanding a level of transparency that the company has avoided for two decades. Whether the market is ready to price in the "orbital data center" narrative remains the $75 billion question.
