SpaceX, IREN Both Buy Nvidia Chips: Their AI Margins Couldn't Be More Different
Key takeaways
- SpaceX’s aggressive capital spend contrasts sharply with IREN’s high‑margin, contract‑based AI model, highlighting divergent paths to monetizing NVIDIA chips.
- SpaceX $40 billion raise ($10 billion loans, $30 billion debt)
- SpaceX $23.6 billion AI capex H1 2026
- SpaceX $15.8 billion AI capex Q2 2026
What happened
SpaceX plans to raise $40 billion—$10 billion in bank loans and $30 billion in investment‑grade debt—to buy NVIDIA chips, while IREN Ltd. has a five‑year Microsoft agreement worth about $9.7 billion to sell NVIDIA‑powered compute. SpaceX’s AI capital spend hit $23.6 billion in H1 2026, with $15.8 billion in Q2 alone, and AI revenue was $2.56 billion that quarter. IREN’s AI Cloud generated $128.8 million in FY 2026 revenue against $16.9 million cost of revenue, implying ~87 % gross margin,…
Why it matters
The two companies illustrate the spectrum of AI business models: SpaceX is investing heavily to own and deploy compute at scale, while IREN monetizes compute capacity through recurring revenue contracts. Their differing capital intensity and margin profiles signal how the AI industry may allocate profits between…
Short-term and longer-term
Short-term. Over the next few weeks, watch SpaceX’s debt issuance and any updates on AI revenue growth; a spike in AI revenue could justify the $40 billion raise.
Longer-term. For investors, the story underscores a strategic choice: bet on owning AI hardware (SpaceX) versus monetizing it through services (IREN).
