# Starlink's $3B annual free cash flow must subsidize $15-20B in combined annual capital deployment across xAI, Terafab, and Starship, making IPO proceeds structurally required for orbital AI ambitions

SpaceX's 2025 financials expose a fundamental capital allocation problem that makes the IPO a prerequisite for the company's stated ambitions rather than an optional financing event. Starlink, the only profitable business segment, generates approximately $3B in annual free cash flow from $11.4B revenue at 63% adjusted EBITDA margins. Against this, the company faces three massive capital consumers: (1) xAI operations burning $28M/day or $10.2B annually post-acquisition, (2) Terafab's $25B commitment over approximately 5 years ($5B/year), and (3) ongoing Starship development consuming multi-billion dollars annually (historically $15B+ total, suggesting $3-5B/year current run rate). The total annual capital requirement is $18-20B against $3B in organic free cash flow—a 6-7x gap. This arithmetic makes the $75B IPO fundraise not a liquidity event but a structural necessity. Without it, neither Terafab nor the orbital AI data center constellation can proceed as planned. The timing is revealing: the S-1 was filed in April 2026, just two months after the xAI acquisition closed in February 2026, suggesting the IPO was always the planned mechanism to finance the combined entity's capital-intensive roadmap. This reframes the entire orbital AI strategy as IPO-contingent rather than organically fundable.
