SemiAnalysis published an analysis arguing that SpaceX's stated plan, announced by Elon Musk on the company's first earnings call, to add an incremental 6-8GW of datacenter capacity in 2027 — possibly above 10GW — is achievable, implying $300-500B of 2027 capex at roughly $50B per GW. The firm models SpaceX reaching about 10GW by year-end 2027 (versus ~2GW at year-end 2026) and a path to ~$300B ARR, assuming only half of incremental compute is monetized at $30-50M/MW/year with 3-5 month lead times and 90-day cancellation terms, financed partly by Nvidia vendor financing following Musk's declared Nvidia exclusivity. It estimates OpenAI, Anthropic and Microsoft can each generate over $100B/GW/year of API inference revenue on GB300 clusters against ~$12B/GW/year of cost at $3/GPU-hr.
