NASA and the Pentagon are becoming a smaller part of SpaceX’s business. But an unexpected AI customer is now paying billions, Starlink is generating substantial operating profits, and Musk’s company is facing a financial challenge that many AI giants already know too well.
When people think about how Elon Musk makes money through SpaceX, rockets, NASA missions and government contracts usually come to mind.
But that picture is becoming outdated.
SpaceX is transforming into something much bigger than a rocket-launching company. It now makes money from satellite internet, artificial intelligence computing infrastructure, software platforms and commercial space services.
The transformation is so significant that Musk recently predicted payments from U.S. government agencies would represent less than 10% of SpaceX’s revenue in the fourth quarter of 2026, falling below 5% within a year.
That raises a fascinating question:
If the U.S. government is no longer SpaceX’s biggest source of money, who is actually paying Elon Musk billions of dollars?
The answer is surprising. Millions of ordinary internet subscribers, airlines, maritime companies, commercial customers and some of the world’s biggest technology businesses are helping finance SpaceX’s expansion.
But there is another question worth asking.
Artificial intelligence companies are spending enormous amounts on GPUs, data centers and electricity. Some are reporting substantial losses despite rapid revenue growth.
Could SpaceX’s AI business face the same problem?
Its latest financial results reveal an interesting answer: SpaceX is profitable overall, but its AI division’s profitability is much less straightforward.
Let’s break down where the money comes from, who the customers are and what the financial numbers actually reveal.
1. SpaceX Has Three Major Businesses, Not Just Rockets
The biggest misunderstanding about SpaceX is that people often associate its entire business with launching rockets.
In reality, its third-quarter 2026 financial filing divides the company into three operating segments:
- Space: Rocket launches, spacecraft and related space services.
- Connectivity: Starlink satellite internet and enterprise connectivity.
- Super Intelligence (SI): AI computing infrastructure, Grok, Cursor and the X platform.
Together, these businesses generated approximately $14.58 billion in revenue during the third quarter of 2026.
Here is how that revenue was distributed:
| Business segment | Q3 2026 revenue | Share of total |
|---|---|---|
| Super Intelligence (AI) | $7.56 billion | 51.9% |
| Connectivity (Starlink) | $5.25 billion | 36.0% |
| Space (rockets) | $1.77 billion | 12.1% |
| Total | $14.58 billion | 100% |
<em>Source: SpaceX Q3 2026 Form 10-Q. Percentages calculated from reported segment revenue.</em>
Think about what these numbers mean.
More than half of SpaceX’s quarterly revenue now comes from its Super Intelligence business.
The rocket business, which made SpaceX famous, contributes only about 12% of total revenue.
This is a dramatic transformation.
SpaceX is increasingly making money from selling connectivity and computing power rather than simply sending rockets into orbit.
2. Who Is Actually Buying From SpaceX?
SpaceX has a much wider customer base than many people realize.
Its customers can be divided into four major groups.
A. Millions of people paying for Starlink internet
The first major customer group is ordinary consumers.
Starlink sells satellite broadband subscriptions directly to households and individual users.
Unlike traditional internet providers that depend on underground cables and local infrastructure, Starlink uses a network of low-Earth-orbit satellites to provide internet connectivity.
Customers pay for monthly subscriptions and, in many markets, purchase or lease the necessary equipment.
The scale is already substantial.
According to SpaceX’s September 2026 filing, Starlink had approximately 13.6 million consumer subscribers, compared with 7.2 million a year earlier.
That is an increase of nearly 89%.
The company also earns money from commercial connectivity services that are not included in this consumer subscriber figure.
This is important because Starlink creates something many AI businesses do not have: a large recurring customer base that pays for an everyday service.
People need internet access regardless of whether a new AI model launches or an AI investment cycle slows down.
B. Airlines, ships and large businesses
Starlink is not just for households.
Its enterprise business sells connectivity to organizations that need reliable internet in places where conventional networks may be unavailable or insufficient.
Important customer categories include:
- Airlines requiring in-flight internet.
- Shipping companies operating vessels across oceans.
- Maritime operators and offshore businesses.
- Companies operating in remote locations.
- Businesses requiring connectivity across multiple countries.
- Telecommunications providers exploring satellite-to-mobile services.
A particularly interesting development is aviation.
SpaceX reported that growth in enterprise and government revenue was primarily driven by additional aircraft activations.
This suggests that commercial aviation is becoming an increasingly important source of income.
Think about the economics.
A household might pay a monthly subscription for internet. An airline can purchase connectivity for an entire fleet of aircraft.
That creates a different commercial opportunity, potentially involving larger contracts and long-term relationships.
C. AI companies renting computing power
This is where the story becomes particularly interesting.
Building an advanced AI model requires enormous computing resources.
Companies need thousands of powerful GPUs, data centers, electricity, cooling systems and high-speed networking infrastructure.
Not every AI company wants to build all of that infrastructure itself.
Instead, it can rent computing capacity from companies that already own or operate large data centers.
SpaceX has entered this market through its Colossus computing facilities in Memphis, Tennessee.
Its AI infrastructure business provides computing capacity to outside customers.
One of those customers is Anthropic, the company behind Claude.
Bloomberg identified Anthropic as SpaceX’s largest individual customer after SpaceX disclosed that an unnamed customer accounted for 34.5% of its third-quarter revenue.
That percentage represents approximately $5.03 billion of quarterly revenue when applied to SpaceX’s reported total.
The calculation is illustrative; SpaceX does not identify the customer by name in its filing.
The relationship is substantial. SpaceX’s earlier SEC prospectus disclosed a cloud services agreement under which Anthropic agreed to pay approximately $1.25 billion per month through May 2029, with computing capacity ramping up during the initial months.
This is a very different source of income from selling rocket launches.
SpaceX is effectively renting out the computing infrastructure that AI companies need to develop and operate their products.
D. Commercial satellite operators and government customers
SpaceX also sells launch services to customers that want to put satellites into orbit.
These include commercial satellite operators, organizations running space missions and government agencies.
A company that wants to launch a satellite does not necessarily need to build its own rocket.
It can purchase a launch service from SpaceX.
NASA and the Department of Defense remain important customers, particularly for astronaut transportation, national security launches and space-related development work.
However, they are no longer the only major source of income.
The important distinction is that government revenue is becoming a smaller percentage of a much larger business.
3. The $5 Billion Customer That Changes the Entire Story
SpaceX’s latest filing contains a number that deserves more attention than Musk’s government revenue prediction.
One unnamed customer accounted for 34.5% of total revenue in the third quarter.
Bloomberg identified that customer as Anthropic.
Let’s put the number into perspective.
SpaceX generated $14.58 billion in quarterly revenue.
A 34.5% share translates into approximately $5.03 billion.
That is more than the entire quarterly revenue generated by Starlink’s Connectivity segment.
It also exceeds the revenue of SpaceX’s traditional rocket business by a considerable margin.
But this creates an important risk.
What happens if Anthropic reduces its computing requirements, switches providers or develops more of its own infrastructure?
SpaceX could suddenly have a significant amount of computing capacity that needs new customers.
The agreements also contain termination provisions allowing either party to end the relevant arrangements with 90 days’ notice after the initial contractual periods.
This does not mean Anthropic plans to leave.
But it means SpaceX’s growing AI revenue should not automatically be treated as guaranteed long-term income.
The company may be reducing its dependence on Washington while becoming more dependent on one major AI customer.
That is the financial contradiction at the center of SpaceX’s transformation.
4. If AI Companies Are Losing Money, Is SpaceX Actually Profitable?
This is probably the most important question.
The AI industry has become famous for enormous investment requirements.
Companies spend billions developing models, purchasing GPUs, securing electricity and building data centers.
Revenue can grow rapidly, but infrastructure costs can grow just as quickly.
SpaceX’s financial results show why looking only at revenue can be misleading.
In the third quarter of 2026, its Super Intelligence division generated $7.56 billion in revenue.
Its reported operating costs and expenses were approximately $7.13 billion.
That left the segment with operating income of approximately $431 million.
<em>In other words, the AI business did report an operating profit for Q3 2026.</em>
However, the bigger picture is more complicated.
During the first nine months of 2026, the same segment generated $10.94 billion in revenue but reported an operating loss of approximately $3.30 billion.
That means one profitable quarter does not establish that the AI business has achieved sustained profitability.
Here is the comparison:
| Financial metric | Q3 2026 | First 9 months of 2026 |
|---|---|---|
| AI revenue | $7.56B | $10.94B |
| AI operating income/loss | +$431M | -$3.30B |
| Starlink operating income | +$2.37B | +$5.21B |
| Space segment operating income/loss | -$7M | -$1.21B |
These are reported operating figures, not adjusted EBITDA.
The difference matters because operating income includes depreciation and amortization, which are particularly significant for businesses investing heavily in computing infrastructure.
The figures reveal something unexpected:
Starlink, rather than AI, is currently the most consistent operating profit engine inside SpaceX.
The satellite internet business generated approximately $5.21 billion in operating income during the first nine months of 2026.
That profit helps support the company’s enormous investment ambitions.
5. Why SpaceX Can Make Money While Other AI Companies Report Huge Losses
The answer comes down to business structure.
SpaceX does not operate only as an AI model developer.
It owns businesses that generate revenue from different markets.
Consider the difference.
An AI company focused primarily on developing large language models must spend heavily on computing infrastructure, research, engineers and product development.
It may have millions of users but still struggle to turn those users into enough paying customers to cover its costs.
SpaceX has additional sources of income.
Its Starlink business sells subscriptions. Its rocket division sells launch services. Its AI division rents computing capacity and operates software platforms.
This creates a diversified revenue structure.
It also means that SpaceX does not need every business segment to be profitable in every quarter for the entire company to report a profit.
Starlink can generate substantial operating income even while the rocket and AI businesses absorb significant development costs.
However, diversification does not eliminate risk.
The company is making enormous investments in infrastructure, and the profitability of its AI segment remains a major question.
6. The Most Surprising Financial Number: SpaceX Spent Nearly $40 Billion on AI Infrastructure
Revenue is only half the story.
The other half is the money required to build the infrastructure behind it.
SpaceX reported approximately $39.995 billion in capital expenditure for its Super Intelligence segment during the first nine months of 2026.
That is an extraordinary amount of investment.
It reflects the scale of the company’s ambition to build computing capacity, purchase equipment and expand its data center infrastructure.
This is where the economics of AI become complicated.
A data center is not simply a building containing computers.
It requires:
- Thousands of high-performance GPUs.
- Reliable and enormous electricity supplies.
- Advanced cooling systems.
- Networking infrastructure.
- Backup power systems.
- Land, construction and engineering.
- Ongoing maintenance and hardware replacement.
The hardware also loses value over time.
New generations of GPUs can make older equipment less competitive, while AI models require increasingly sophisticated computing resources.
A company can report strong operating revenue while simultaneously spending tens of billions on expansion.
That is why investors need to distinguish between three different things:
Revenue: How much money the business earns from customers.
Profit: How much remains after the costs recognized in the income statement.
Free cash flow: How much cash remains after operating expenses and capital investment.
A company can report accounting profit and still consume enormous amounts of cash when it is expanding rapidly.
SpaceX’s AI infrastructure investment makes that distinction particularly important.
7. Is SpaceX Really Making a Profit? The Answer Depends on Which Numbers You Look At
SpaceX reported $4.40 billion in net income for the third quarter of 2026.
At first glance, that looks impressive.
Its total operating income was approximately $2.79 billion.
However, there is an important accounting detail.
The company also reported substantial interest income and other income during the quarter.
Among the items disclosed in its filing was a $561 million unrealized gain on an investment in TBC, a related-party investment.
The company also reported $873 million in interest income.
These items helped increase reported net income beyond operating income.
The nine-month figures tell a different story.
For the first nine months of 2026:
- Revenue: $27.08 billion.
- Operating income: $705 million.
- Net loss: approximately $413 million.
Why?
Interest expenses, other expenses and other financial items reduced the result below the operating profit level.
So the accurate conclusion is not that SpaceX is consistently generating billions in profit from every part of its business.
It is that the company reported a profitable third quarter, while its first-nine-month net result remained slightly negative.
Its AI division also remained loss-making over that nine-month period.
This is precisely why headline revenue and quarterly profit should never be treated as the complete financial picture.
8. Anthropic Is Spending Billions Too. Is the AI Business Model Sustainable?
There is another layer to this story.
SpaceX’s biggest AI customer is itself facing the economics of enormous infrastructure spending.
Anthropic’s 2026 SEC filing reported:
- Revenue of approximately $33.24 billion for the first nine months of 2026.
- Compute and infrastructure expenses of approximately $18.81 billion during the same period.
- A reported net loss of approximately $104.04 billion.
That last number needs an important qualification.
A substantial portion of Anthropic’s reported net loss was connected to a roughly $94.3 billion accounting adjustment involving the valuation of financing-related instruments.
That means the headline net loss should not be interpreted as $104 billion of cash burned by ordinary business operations.
Anthropic’s filing also reported adjusted operating income of approximately $4.1 billion for the first nine months of 2026, illustrating how significantly accounting adjustments and financing structures can affect reported results.
This creates an unusual relationship.
SpaceX sells computing capacity to Anthropic.
Anthropic uses that computing capacity to develop and operate AI products that it sells to businesses and consumers.
Both companies are investing heavily in the future of artificial intelligence.
But both depend on the economics of AI demand continuing to grow.
If companies and consumers are willing to pay more for AI services, the model could become extremely profitable.
If computing demand slows, prices decline or customers reduce their spending, the financial pressure could spread throughout the entire infrastructure chain.
The AI industry is therefore not just a competition between chatbot companies.
It is also a competition between the businesses that own the infrastructure and the companies that rent it.
9. Could Starlink Be SpaceX’s Secret Financial Safety Net?
Perhaps the most overlooked part of this entire story is Starlink.
While AI attracts attention because of its enormous growth potential, satellite internet provides SpaceX with a different kind of business.
Customers pay recurring subscription fees.
Businesses purchase connectivity packages.
Airlines and ships need communication services.
Remote communities and organizations need internet access where traditional networks are difficult to deploy.
This creates recurring demand.
In the third quarter of 2026, Connectivity generated approximately $2.37 billion in operating income.
For the first nine months, it generated approximately $5.21 billion.
That makes Starlink the company’s strongest operating profit contributor among its three reported segments.
It also gives SpaceX an advantage that a company dependent entirely on AI model development may not have.
Starlink can generate income from customers who are not buying AI products.
It does not need every consumer to subscribe to Grok or every enterprise to purchase computing capacity.
This separation of revenue sources could prove important if the AI industry experiences a slowdown.
However, Starlink also requires continuous investment in satellites, ground infrastructure and network capacity.
It is not a business without costs or competitive challenges.
10. The Biggest Risk Is No Longer Just Government Dependence
Musk’s prediction that government revenue will fall below 5% of SpaceX’s total revenue is certainly significant.
But the more important question is whether SpaceX is becoming financially diversified enough to sustain its enormous ambitions.
Three risks deserve attention.
Customer concentration: One AI customer accounted for 34.5% of quarterly revenue. That is a substantial dependence on a single commercial relationship.
Infrastructure spending: SpaceX is committing tens of billions of dollars to computing capacity. Those investments must generate enough future revenue to justify their cost.
AI market uncertainty: AI demand is growing, but competition, pricing pressure, hardware depreciation and customer spending could change the economics quickly.
There is also a political risk.
Even if government contracts become a smaller percentage of total revenue, NASA and the Pentagon remain strategically important customers. A deterioration in those relationships could affect future programs and national security work.
The company is not simply replacing one source of income with another without consequences.
It is changing the nature of its financial risks.
Final Verdict: SpaceX Is More Than a Rocket Company, but Its AI Profit Story Is Not Yet Settled
So, who is paying Elon Musk’s SpaceX if the U.S. government contributes less than 10% of its revenue?
The answer is millions of Starlink subscribers, airlines, maritime companies, commercial satellite operators, AI businesses such as Anthropic and other enterprise customers.
The company’s financial structure has changed dramatically.
AI computing now contributes more than half of quarterly revenue, while Starlink provides the strongest operating profit contribution.
SpaceX reported $4.40 billion in net income for the third quarter of 2026, but its first-nine-month results still showed a net loss of approximately $413 million.
Its AI division reported an operating profit in Q3, but remained in the red over the first nine months.
That is the distinction readers should remember.
SpaceX has demonstrated that it can make money from AI infrastructure, but it has not yet demonstrated that its enormous AI investment can deliver consistently sustainable profits.
The real test will be whether it can turn its growing computing capacity into long-term customer demand, diversify beyond Anthropic and generate enough cash to justify its infrastructure spending.
Musk may be making SpaceX less dependent on Washington.
But the next chapter of the company could depend on something much bigger: whether the global AI industry can turn its extraordinary spending into extraordinary profits.
