The Trillion-Dollar Gap | We Asked Aswath Damodaran What SpaceX Is Really Worth

Space Launch Cost Dominance

SpaceX revolutionized the industry with reusable rockets, creating a 60% cost advantage that allows them to control the growing satellite launch market.

Starlink's Niche Revenue Stream

Generating $15 billion (60-70% of total revenue), Starlink serves remote areas and airlines but remains technologically inferior to fiber optics for urban users.

The XAI Acquisition Gamble

The February 2026 merger added Grok to compete in AI, but this business currently has negative margins and unproven unit economics despite claims of a $26 trillion addressable market.

Growth Can Destroy Value

Damodaran warns that AI expansion accompanied by massive reinvestment and substandard gross margins is potentially value-destructive rather than accretive.

The $26 Trillion Market Mirage

While bankers cite a massive total addressable market, delivering high-end AI costs thousands per hour with no clear path to profitability or economies of scale.

Conflicting Business Models

SpaceX plans to dominate AI while simultaneously renting data center space to competitors like Google and Anthropic, creating a fundamental strategic contradiction.

Story-Driven Fundamentals

With limited financial history and current losses driven by R&D expenses, Damodaran valued each business separately based on optimistic future narratives rather than historical data.

The Unit Economics Problem

Unlike software, AI lacks marginal cost advantages because data center power and water costs prevent margin expansion as revenue scales.

Accounting for Intangibles

Treating R&D as an operating expense artificially depresses reported earnings, but even correcting this leaves the company with thin margins dependent on uncertain future execution.
