SpaceX IPO Explained: 3 Massive Pillars Driving the Future of Tech, AI, and Space
For most people, SpaceX still feels like a company from a science-fiction movie. Rockets landing back on Earth, satellites covering the planet with internet, plans to go to Mars, and now even AI data centres in space.
But behind all the excitement, the SpaceX IPO is asking one simple question:
Is this just a rocket company, or is SpaceX becoming one of the most important infrastructure companies of the future?
The answer is not straightforward. SpaceX is no longer only about launching rockets. It is building 3 businesses together, space launches, satellite internet through Starlink, and artificial intelligence infrastructure. The interesting part is that all 3 are connected. The rocket business helps Starlink grow. Starlink generates cash. And both of them may help SpaceX build its future AI business.
That is why this IPO is not a normal IPO. Investors are not just buying a company. They are buying a vision.
As per the IPO details, SpaceX plans to issue 555.6 million shares at $135 per share, raising around $75 billion. This is a fresh issue, which means the money will go to the company for expansion rather than to existing shareholders. The company plans to list on Nasdaq / Nasdaq Texas under the ticker SPCX. The funds will be used mainly for AI compute infrastructure, launch infrastructure, satellite constellation expansion and general corporate purposes.
Now let us understand how SpaceX actually makes money.
The 1st business is the Space business. In simple words, SpaceX owns rockets and customers pay it to carry satellites, cargo or people into space. NASA, the US Department of Defense, telecom companies, satellite operators and private companies are major customers. Think of it like a cargo airline business, but instead of moving goods from Mumbai to Delhi, SpaceX moves payloads from Earth to orbit.
The biggest advantage here is reusable rockets. Earlier, most rockets were used once and thrown away. That made space launches extremely expensive. SpaceX changed this model by landing and reusing rocket boosters. This is like using the same aircraft for multiple flights instead of buying a new aircraft for every journey. Because of this, SpaceX has been able to bring down launch costs sharply. Falcon 9’s cost to low Earth orbit is around $2,700 per kg compared with the historical average of around $18,500 per kg.
This cost advantage is the foundation of everything else SpaceX does.
In 2025, the Space segment reported revenue of $4.1 billion and adjusted EBITDA of $0.7 billion. Adjusted EBITDA means operating profit before interest, tax, depreciation and amortisation, adjusted for certain items. But these numbers do not tell the full story. Why? Because SpaceX also uses its own rockets to launch Starlink satellites. It does not charge itself fully for these internal launches. So, the Space business may look smaller on paper, but economically it is the engine that powers the rest of the company.
The second and most commercially proven business is Starlink, which comes under Connectivity.
This is the easiest business to understand. SpaceX has placed thousands of satellites in low Earth orbit. These satellites provide internet to homes, ships, aircraft, remote factories, rural areas, disaster zones and defence users. Customers buy a Starlink device and pay a monthly subscription.
In simple terms, Starlink is like a global internet provider from space.
This is powerful because traditional internet infrastructure has limitations. Fibre cables and mobile towers are difficult to build in remote villages, mountains, oceans, aircraft and war zones. Starlink solves this by sending internet directly from satellites.
The numbers are already impressive. Starlink had around 10.3 million subscribers by Q1 2026, with coverage across 164 countries. Connectivity revenue grew from $3.9 billion in 2023 to $11.4 billion in 2025. More importantly, adjusted EBITDA increased from $1.6 billion to $7.2 billion during the same period. Margins improved from 41% to 63%.
This tells us something important. Once the satellite network is built, every new customer can become highly profitable. The fixed cost is already spent on satellites, ground stations and launches. So, as more subscribers join, profits can grow faster than revenue. This is called operating leverage. In simple words, the business becomes more profitable as it gets bigger.
Starlink also has multiple customer segments. Regular consumers pay for home internet. Enterprises such as airlines, shipping companies and remote industrial sites pay higher monthly charges. Governments use secure versions like Starshield for defence and emergency communication. Mobile operators can partner with Starlink Mobile to reduce dead zones where normal network coverage is weak.
That is why Starlink is currently the strongest part of the SpaceX story. It is not just a future dream. It is already a large, fast-growing and profitable business.
The third business is AI, and this is where the story becomes more ambitious — and more risky.
SpaceX’s AI segment includes X, Grok and AI compute infrastructure. X earns mainly from advertising and subscriptions. Grok is the AI assistant and can earn through consumer subscriptions, enterprise use and API access. API simply means allowing other companies to use Grok’s AI capabilities inside their own apps or products.
The company also talks about Colossus, a large AI supercomputer infrastructure. SpaceX wants to sell compute capacity to other AI companies. Compute means the processing power required to train and run AI models. As AI becomes bigger, companies need more GPUs, more electricity and more data centre capacity. SpaceX believes this is a massive opportunity.
In 2025, the AI segment reported revenue of $3.2 billion, but adjusted EBITDA was negative $1.2 billion. So, unlike Starlink, this business is still in heavy investment mode. The company claims around 550 million monthly active users across X and Grok, and around 117 million monthly active users using Grok’s AI features.
But the boldest part is orbital AI compute. SpaceX argues that AI data centres on Earth face three major problems: power shortage, land availability and cooling cost. Its proposed solution is to place AI compute satellites in space, powered by solar energy and supported by Starship launches.
This is exciting, but investors should be careful here. Starlink is proven. Falcon is proven. But orbital AI compute is still an idea that needs execution. It may become revolutionary, but it is not yet a mature business.
Financially, SpaceX is growing fast but spending even faster.
Total revenue increased from $10.4 billion in 2023 to $18.7 billion in 2025. Adjusted EBITDA increased from $3.8 billion to $6.6 billion. These are strong numbers. However, the company reported a GAAP net loss of $4.9 billion in 2025. GAAP net income means profit calculated using standard accounting rules.
Why is the company still loss-making despite strong EBITDA?
The main reason is heavy capital expenditure and depreciation. Capital expenditure, or capex, means money spent on long-term assets such as rockets, satellites, launch pads and data centres. SpaceX’s capex increased from $4.4 billion in 2023 to $20.7 billion in 2025. Once these assets are built, accounting rules require the company to charge depreciation over time. Depreciation is a non-cash expense, but it reduces reported profit.
So, SpaceX is currently in build mode. It is investing heavily today in the hope that these assets generate large profits in the future.
Now comes valuation.
At the IPO price of $135 per share, the pre-money valuation is estimated at around $1.69 trillion. Pre-money valuation means the value of the company before adding IPO proceeds. After adding the fresh capital raised, the post-money valuation is around $1.765 trillion. On 2025 revenue of $18.7 billion, this is a very expensive valuation, indicates an approximate P/S of 94x. P/S means price-to-earnings ratio. It tells us how much investors are paying for every dollar of sales. A high P/S is not always bad if the company can grow very fast for many years. But it also means the company must execute almost perfectly. Any delay in Starship, slowdown in Starlink, higher AI losses or regulatory problem can hurt investor confidence.
This brings us to one of the biggest risks: corporate governance.
The prospectus highlights that SpaceX will have 2 classes of shares. Class A shares will have 1 vote/share, while Class B shares will have 10 votes/share. The public offering will be Class A shares. Elon Musk will hold all Class B shares, giving him control over more than 85% of the voting rights.
This means public shareholders may own the stock, but they will have very little control over major company decisions.
In founder-led companies, this structure can work very well when the founder keeps creating value. But it also creates risk. Shareholders may not have much say in board decisions, related-party transactions, capital allocation, leadership succession or strategic direction.
This is especially important because Elon Musk is involved in several large businesses — Tesla, X, xAI and other ventures. SpaceX’s AI strategy also creates possible overlaps with other Musk-linked companies. Investors must therefore ask: if there is a conflict between different Musk entities, will minority shareholders have enough protection?
That is the real governance question.
So, how should we think about the SpaceX IPO?
SpaceX has 3 layers. The Space business is the foundation. It gives the company low-cost access to orbit. The Connectivity business is the cash machine. Starlink is already scaling fast and generating strong margins. The AI business is the future option. If it works, it can create massive value. If it fails, it can burn a lot of capital.
This is what makes SpaceX both fascinating and risky.
For optimistic investors, SpaceX is one of the rare companies that can create entirely new markets. It has reusable rockets, a global satellite network, a fast-growing internet business and a bold AI infrastructure plan. Very few companies in the world have this kind of combination.
For cautious investors, the concerns are equally clear. The valuation is extremely high. Free cash flow is under pressure. AI and orbital compute are unproven. Starship still has execution risk. And Elon Musk’s voting control means public shareholders will have limited influence.
In the end, the SpaceX IPO is not just about buying a company that launches rockets. It is about buying into a belief that the next generation of internet, AI and space infrastructure may be built by one vertically integrated company.
The opportunity is enormous.
But so is the execution risk.
And that is why investors should not look at SpaceX only with excitement. They should look at it with excitement plus discipline.
