Financial Comparison of SpaceX, Rocket Lab, and AST SpaceMobile
A comparative analysis of three major space industry players reveals divergent financial profiles. SpaceX (SPCX) reported $14.6 billion in Q3 revenue, driven significantly by its 'Super Intelligence' AI segment; however, massive capital expenditures totaling $40 billion for AI infrastructure have resulted in nearly $35 billion in negative free cash flow for the first nine months of 2026. Rocket Lab (RKLB) generated $234 million in Q2 revenue, primarily through its Space Systems segment, but faces challenges with negative free cash flow and potential equity dilution following its Iridium acquisition. Meanwhile, AST SpaceMobile (ASTS) remains in a pre-revenue stage for its satellite-cellular service, reporting only $31.5 million in Q2 revenue, leaving its valuation heavily dependent on future commercialization success.
