Why Starlink became the core of SpaceX's current revenue
At 8:40 · chapter starts 5:31
Starlink now generates 60–70% of SpaceX revenues via 10,000 satellites; its coverage advantage stems directly from SpaceX's launch cost edge.

Starlink Built SpaceX Into a Real Business
SpaceX started as a space launch company, but the real commercial breakthrough was Starlink: broadband internet from 10,000 satellites in orbit. Because SpaceX launches satellites cheaper than anyone else, Starlink has coverage competitors can't match — and it now generates 60–70% of SpaceX's revenues. Without Starlink, SpaceX would still be a niche business.
SpaceX has 10,000 satellites in orbit
Starlink's competitive moat rests on having approximately 10,000 satellites in space, giving it coverage that no other satellite-based internet provider can match.
Starlink: ~60-70% of SpaceX revenue
The Starlink connectivity business accounts for roughly 60–70% of SpaceX's total revenues, making it the core commercial engine of the company.
The $26 Trillion Mirage: AI's Big Market Delusion
SpaceX's prospectus claims a $26 trillion AI total addressable market — the largest Damodaran has ever seen. But a big market with poor unit economics and massive reinvestment needs can destroy value rather than create it. Getting to revenue and profit from a large TAM requires a chain of assumptions most analysts never complete.
Claude Fable costs ~$6,000/hour to use
The high-end AI model Claude Fable reportedly costs around $6,000 per hour to use, and Anthropic does not profit from it because the delivery costs are comparably high.
AI Unit Economics: The Unsolved Problem
Claude Fable reportedly cost $6,000 per hour to use — and Anthropic still lost money on it. The costs come from data centers, power, and water that don't benefit from traditional economies of scale. Until someone solves the unit economics of high-end AI, the entire LLM industry is competing for a market where profits may structurally not exist.
