Why Analysts Are Getting SpaceX Wrong
– Most analysts are feeling one part of the elephant understand space but not AI or understand neither
– S1 (300-page F1) only covers through Q1 last year, predates the AI revenue pivot
– Many still exclude the new AI contract revenue from 2026 projections
– JPMorgan, Morgan Stanley, and others have since validated Brian’s original numbers
– Key numbers now validated Revenue $40B this year, $80B next year, $160B the year after
The AI Revenue Case
– xAI already #2 in AI cloud rental, ahead of Google and Amazon on all cloud revenue
– Current run rate: $26B/year in signed contracts (up from under $1B), mostly profit
– Only using 40% of Colossus 2. Fully rented out colossus 1 and 2, run rate goes to $64B/year
– Full Colossus 1 + 2 rental would exceed Microsoft, Amazon, and Google cloud combined
– Rubin chips (500K GPUs, ~1 GW). worth ~$100B+/year in rental revenue
– If xAI replicates Anthropic’s model capability, inference value 10x, pushing toward $300-400B/year
– Jensen Huang at Sequoia VC conference 1 GW of data center worth $300-400B/year. Complete AI data centers are worth more than components alone
– xAI can build new data centers in ~1 year vs. 4 years for competitors
– Cursor acquisition closing gap with Anthropic’s Claude Code. Grok training 10x faster. Models expected to converge
