Zhihu Analysis: Sky-High IPOs and Stock Market Crash History
SpaceX, OpenAI, Anthropic stacking sky-high IPOs; historical pattern of mega-IPOs before crashes — does it hold?
Original Core Argument
Historical pattern: Two major US stock crashes were preceded by sky-high IPOs:
- 2000 dot-com bubble: AT&T Wireless IPO $10.6B
- 2008 financial crisis: Visa IPO $17.9B
Conclusion: Sky-high IPOs don’t necessarily cause crashes, but crashes are always preceded by sky-high IPOs. 2026 AI-related mega-IPOs are here, bubble may burst.

Logic Analysis
What the Article Gets Right
Historical case analysis is valuable
- AT&T Wireless IPO did occur at dot-com bubble peak
- Visa IPO did occur at start of financial crisis
- These cases deserve investor attention
AI bubble warning
- SpaceX, OpenAI, Anthropic valuations are indeed high
- None are profitable yet (OpenAI Q1 loss $4.28B)
- Sky-high IPOs may be bubble signals
“Bubble will burst, but AI potential not denied”
- This is a balanced stance
- Distinguishes short-term bubble from long-term value
Where the Article Falls Short
Sample size too small
- Only 2 major crashes — not statistically significant
- Selection bias: ignores many cases where mega-IPOs were followed by continued rallies
Correlation ≠ causation
- Sky-high IPOs may be result of bubble, not cause
- Chain: Bubble → Mega-IPO → Crash, not Mega-IPO → Crash
Counter-examples ignored
- 2012 Facebook IPO ($16B) — market continued up
- 2014 Alibaba IPO ($25B) — market continued up
- These counter-examples are ignored
Historical analogy issues
- 2000 was dot-com, 2026 is AI
- Market structure, liquidity, investor composition all different
- Simple analogy may miss key differences
Conclusion
This article’s historical case analysis is valuable, warning investors about mega-IPO risks. But the “mega-IPO → crash” logic is oversimplified, sample size too small, counter-examples ignored.
More accurate statement: Sky-high IPOs may be one bubble signal, but not a sufficient condition. Investors should monitor valuations, earnings, liquidity — not just IPO size.
One-line summary: Historical cases have value, but “mega-IPO → crash” logic is oversimplified and ignores counter-examples.
