HAWTHORNE, Calif. — When SpaceX begins trading on the Nasdaq under the ticker SPCX on June 12, investors will effectively be buying a satellite internet company that also happens to operate the world's most prolific rocket program. That is the picture that emerges from the company's IPO prospectus, which reveals just how dominant Starlink has become within SpaceX's overall business.
Starlink generated $11.39 billion in revenue in 2025, representing 61 percent of SpaceX's total sales for the year. By the first quarter of 2026, that share had risen further to 69 percent — a concentration that reflects both Starlink's rapid subscriber growth and the still-nascent status of SpaceX's newer revenue streams.
Subscriber Base More Than Doubled
The subscriber trajectory driving these numbers is significant. Starlink's user base surpassed 10.3 million in the first quarter of 2026, more than doubling from the same period a year earlier. The growth has been fueled by continued geographic expansion — Starlink now provides service across more than 100 countries — as well as new market segments including aviation, maritime, and government customers.
Aviation has emerged as a particularly strong growth vertical. Airlines including United, Qatar Airways, and Air France have deployed Starlink across their fleets, offering passengers seamless connectivity without the captive portals or per-session fees that defined earlier in-flight Wi-Fi. Government customers, including the U.S. military and several international agencies, have expanded their Starlink contracts substantially.
The Only Profitable Division
Starlink's financial contribution goes beyond revenue. It was the only SpaceX division to post operating profit in 2025, generating $4.42 billion in income. The rocket launch segment, which includes commercial, government, and national security payloads for Falcon 9 and Falcon Heavy, posted a $657 million deficit — a figure that reflects the significant costs of maintaining SpaceX's aggressive launch manifest.
The AI division, which accounts for the computational infrastructure and ongoing development costs absorbed following the February 2026 xAI acquisition, carried a $6.35 billion deficit for the year. SpaceX has begun monetizing that infrastructure through compute partnerships: Google has committed $920 million per month through June 2029, and Anthropic has agreed to $1.25 billion per month through May 2029 — deals that could contribute more than $100 billion in combined revenue before they expire.
Wall Street Prepares for a Historic Debut
The financial disclosures have prompted significant preparation by the institutions managing SpaceX's market entry. S&P Global's Equity Bookbuild division spent weeks expanding its infrastructure ahead of what could become the largest-volume first trading day in Nasdaq history. Several major banks reportedly organized internal watch parties for the June 12 debut, with stress-testing of settlement and clearing systems conducted in the days preceding the listing.
SpaceX's fixed $135-per-share price targets raising $75 billion — exceeding Saudi Aramco's 2019 IPO to become the largest public offering in history. At that price, Starlink's $11.39 billion in annual revenue implies a revenue multiple of roughly 13x for the satellite division alone, though investors are clearly pricing in a substantial premium for the company's broader ambitions and its unique position at the intersection of space, AI, and telecommunications infrastructure.
A Foundation for What Comes Next
The Starlink numbers matter not just for what they represent today but for what they enable going forward. The satellite division's profitability is the financial engine that funds Starship development, the xAI computing buildout, and the longer-term objectives outlined in the prospectus — including Moon refueling infrastructure, asteroid mining operations, and space-based manufacturing.
SpaceX has effectively solved the challenge that has confronted every prior commercial space company: how to generate reliable, recurring revenue from orbital operations. With 10.3 million subscribers paying monthly fees for high-speed internet, and enterprise and government customers signing long-term contracts, Starlink provides the kind of predictable cash flow that allows SpaceX to plan and invest across decade-long timelines. As the company takes its next step as a public company, that foundation may be its most durable competitive advantage.
