Executive Summary
SpaceX reported revenue of $14.6 billion, up 161% year over year, alongside net income of $4.4 billion. The results provide substantial evidence that its investment in AI infrastructure is becoming recognized revenue. Independent earnings coverage corroborates the company’s filing.
