Summary
SpaceX reported strong Q1 revenue as a publicly traded company following its June 2026 IPO, with most revenue coming from its Starlink satellite business. However, investor focus quickly turned to capital expenditures related to xAI's Grok AI service, which totaled $15.8 billion—significantly exceeding analyst expectations of $13.09 billion and doubling the previous quarter's spending. The higher-than-expected AI spending comprised the majority of SpaceX's overall $18.4 billion quarterly capital expenditure, triggering immediate concerns about the economic viability of the AI investment pace. The report caused SpaceX shares to reverse their strong intraday gains, falling 6.5% in after-hours trading despite having surged 9% during regular hours, with additional pressure expected when the insider lockup period expires Wednesday, allowing up to 20% of insider-held shares to enter the open market.
