SpaceX and IREN show starkly different AI economics despite using Nvidia chips
SpaceX is investing billions to own and run AI infrastructure, while IREN sells access to Nvidia‑powered compute. In the first half of 2026 SpaceX’s AI capex reached $23.6 billion, with $15.8 billion spent in the June quarter, generating $2.56 billion of AI revenue that quarter. IREN’s AI Cloud business produced $128.8 million of revenue in fiscal 2026 and reported an estimated 87% gross margin, compared with SpaceX’s AI segment gross margin of roughly 32% in 2025.
Why it matters
The contrast highlights differing capital efficiency: IREN’s model currently yields a higher share of revenue as profit, which may appeal to investors seeking lower upfront spending, while SpaceX’s approach relies on scaling large‑scale compute to justify its heavy investment. Investors will watch whether IREN can sustain its high margin as it grows and whether SpaceX’s massive spend translates into future profitability.
