The Growth Story Behind The IPO
SpaceX is best known for reusable rockets and its high-profile push into artificial intelligence through its merger with xAI. But as Elon Musk’s company prepares investors for a massive initial public offering, its prospectus shows that Starlink is the business driving most of its growth and profit.
In the filing, SpaceX said its connectivity division, made up primarily of Starlink, generated 11.39 billion dollars in revenue last year. That represented 61% of total company sales. In the first quarter of this year, the figure rose to 69%.
Starlink Outshines Rockets And AI
Starlink was also SpaceX’s only profitable division last year. The satellite internet business generated 4.42 billion dollars in income, while the rocket launch division lost 657 million dollars and the artificial intelligence unit posted a deficit of 6.35 billion dollars.
That contrast is central to SpaceX’s investment case. The company’s most futuristic ambitions, including Mars colonization, orbital data centers and AI infrastructure, remain expensive and uncertain. Starlink, by contrast, is already producing large-scale revenue and profit.
A Global Satellite Internet Network
Starlink provides high-speed internet through more than 10,200 satellites in low Earth orbit, a region within about 1,200 miles of Earth’s surface. Since launching its first satellites in 2019, the service has become the leader in satellite-based internet.
The network is now available across all seven continents and in more than 160 countries. Its user base more than doubled to 10.3 million in the first quarter from a year earlier, strengthening its position ahead of the SpaceX IPO.
A Cash Cow For Bigger Ambitions
Starlink has long been viewed as the business capable of funding SpaceX’s more expensive goals. Musk wants to colonize Mars, build orbital data centers and compete more aggressively in artificial intelligence, but those projects require extraordinary levels of capital.
SpaceX reported 10.1 billion dollars in capital expenditures in the first quarter alone, more than double the year-earlier period. Of that total, 7.7 billion dollars went toward AI, underscoring why Starlink’s profitability is so important to the company’s broader strategy.
Consumers, Airlines And Governments Drive Demand
Starlink has gained traction with consumers, but it also serves commercial and government customers. Airlines including United, Southwest and Hawaiian use the service to provide in-flight internet, while states, charities and emergency organizations often buy terminals after natural disasters.
SpaceX also operates Starshield, a classified version of Starlink designed for military use. Musk said in December that Starlink’s commercial service was by far the largest contributor to SpaceX’s revenue.
Competition Is Increasing
Starlink’s lead is significant, but competitors are building their own satellite constellations. OneWeb, operated by France’s Eutelsat, has more than 600 satellites. Amazon has launched more than 300 satellites and is preparing its Leo service, which is expected to include about 7,700 satellites.
Blue Origin plans to deploy roughly 5,400 satellites beginning in late 2027, while China’s Guowang is working toward a mega constellation. SpaceX listed more than 20 Starlink competitors in its prospectus, including Amazon, Blue Origin, Viasat, AT&T and T-Mobile.
Regulators Remain A Key Risk
Starlink’s global expansion depends heavily on regulatory approvals, spectrum access and local licensing. Some countries have resisted the service because of foreign ownership rules or security concerns.
Namibia denied Starlink’s license application in March, while South Africa’s rules require foreign-owned communications companies to sell 30% of local equity to historically disadvantaged groups. Taiwan has also reportedly ruled out deploying Starlink because SpaceX would not agree to a joint venture with a local partner.
Space Debris And Orbital Data Centers
Starlink also faces environmental and technical concerns. Its satellites typically last only three to five years, meaning the company must continually retire and replace large numbers of units. SpaceX has also asked the FCC for permission to launch up to 1 million low Earth orbit satellites, drawing criticism from groups worried about space debris and light pollution.
At the same time, SpaceX is pitching an even more ambitious future: orbital data centers powered by solar energy and equipped with AI chips. The company says it could begin deploying space-based data centers as early as 2028, though experts warn the concept faces major challenges, including launch capacity, cooling, radiation and cost. For investors, Starlink is the proven engine of SpaceX today, while orbital AI remains the high-risk promise of tomorrow.
