SpaceX’s AI compute revenue leaps 250% to $2.6B, but burns $15.8B in capex

For AI researchers and technologists, SpaceX’s earnings reveal a company sprinting to build the world’s largest AI compute platform. Elon Musk claims SpaceX is “building AI compute capacity at scale faster than anyone else” and “significantly improving our AI models,” an assertion that, if true, could reshape the competitive landscape dominated by hyperscalers. The eye-watering $15.83 billion in quarterly AI capex and the tripling of AI revenue to $2.6 billion signal that SpaceX is treating this as a winner-take-most race—but the $1.3 billion operating loss also underscores that the path to AI profitability is measured in years, not quarters.

SpaceX’s first earnings report as a public company laid bare both the explosive growth and staggering costs of Elon Musk’s multi-industry bet. Second-quarter revenue rocketed 92% to $7.8 billion, beating analyst estimates by roughly $1 billion, fueled by its Starlink satellite internet service and a nascent AI compute business. Starlink, which accounted for more than half of total revenue, saw its subscriber base double to 12 million and its revenue rise 66%, while AI-related revenue surged approximately 250% to $2.6 billion. Rocket launches, historically SpaceX’s core, generated $962 million in revenue but posted a $542 million operating loss. The only profitable segment was Starlink. Yet despite the top-line fireworks, shares slid as investors digested an $18 billion capital expenditure bill for the quarter—an 11-fold increase from $2.83 billion a year earlier—with over $15.83 billion plowed into AI infrastructure alone. Finance chief Bret Johnsen warned that spending would remain at elevated levels over the next couple of quarters, and management acknowledged the AI unit recorded a $1.3 billion operating loss.

The earnings call underscored the core tension: SpaceX is valued at $1.75 trillion on the premise that profits from Starlink can underwrite an enormously expensive buildout of AI compute, next-generation rockets, and a V3 Starlink constellation, long enough for those ventures to become self-sustaining. Musk said that new capital deployments for AI compute would generate a payback in less than a year, and he asserted the company is “building AI compute capacity at scale faster than anyone else” while “significantly improving our AI models.” In parallel, SpaceX promised to launch at least 1,000 V3 Starlink satellites within a year and forecast reaching a $100 billion annualized revenue run-rate by December 2026—a target that assumes continued hypergrowth across all lines.
