We Think the SpaceX IPO Is Overvalued
Morningstar’s claim that the upcoming SpaceX IPO is overvalued has triggered wide skepticism about the company’s growth story, especially its assumptions around reusable Starship rockets and AI-focused “orbital data centers.” Many argue that the physics, maintenance, and economics of data centers in space are fundamentally worse than terrestrial alternatives, making the AI narrative look like hype to justify a $1–2 trillion valuation. Others note that demand for the shares will likely remain strong anyway, driven by retail enthusiasm, index funds, and a cult-like bet on Elon Musk despite concentrated voting control, governance concerns, and a stock market increasingly decoupled from traditional fundamentals.
Orbital Data Centers: Physics & Engineering
- Many commenters argue the physics are hostile:
- Huge mass to orbit (thousands of tonnes for a large DC) implies dozens of Starship launches.
- Cooling in vacuum is hard: radiators must run at very high temperatures; current GPU/HBM limits may be exceeded.
- Radiation, lack of serviceability, and satellite deorbit lifetimes further complicate things.
- Others note SpaceX’s plan is not “a building in space” but many small 100–150 kW satellites, closer to scaled‑up Starlink buses.
- Some think the technical problems are solvable “with enough money”; others call it a “physics/thermodynamics litmus test.”
Orbital Data Centers: Economics & Use Cases
- Critics say launch + hardware + maintenance makes them far more expensive than terrestrial DCs (including remote or offshore options), with no compelling advantage.
- Proponents see potential if:
- Power and land/zoning constraints on Earth bind hard (NIMBY, grid limits).
- High‑value, attack‑resistant compute is needed (military, surveillance, “dissident‑proof” infrastructure).
- Even then, many argue the market would be niche and not justify a trillion‑plus valuation.
Valuation, Markets, and IPO Dynamics
- Thread consensus: IPO is richly priced; often described as a meme/cult stock driven by retail enthusiasm and “betting on” the founder.
- Comparisons made to Tesla, Bitcoin, and other “concept” assets where price is decoupled from fundamentals.
- SpaceX’s own TAM breakdown (space ~$370B, connectivity ~$1.6T, AI ~$26.5T) is seen as heavily reliant on very speculative AI assumptions.
- Some expect index and large‑cap funds to be forced buyers, further supporting price regardless of fundamentals.
Governance and Shareholder Rights
- Prospectus highlights:
- Super‑voting shares give the founder ~85% voting power; public investors have little control over board or CEO.
- Mandatory arbitration and limits on class actions weaken shareholder recourse.
- Several commenters see this as effectively a sole proprietorship with public capital; others note similar dual‑class structures exist elsewhere.
AI, Commoditization, and Long‑Term Risk
- Skepticism that cloud AI subscriptions are a durable goldmine: hardware will get cheaper, on‑device inference will grow, and models may be commoditized (including by China).
- Some argue current AI hype and regulatory capture efforts are a rush to cash out before margins collapse.
Role of SpaceX and Space
- SpaceX is acknowledged as dominant in launches and Starlink‑type connectivity, but many note that:
- Space remains a modest commercial market compared to big tech/AI.
- Much of the IPO valuation is tied to speculative AI lines, not launch or traditional space services.
- A minority of commenters explicitly say they’ll buy shares as a “piece of the future” regardless of valuation.
