Michael Burry’s $379 Newsletter Launch: AI Bubble Thesis vs. Social Media Skepticism

:
According to CNBC[1], Michael Burry launched ‘Cassandra Unchained’—a $379 annual Substack newsletter—after deregistering Scion Asset Management in November 2025. Research indicates the newsletter focuses on his bearish AI bubble thesis, comparing Nvidia (NVDA) to Cisco (1990s dot-com bubble) and warning of “supply-side gluttony” in AI infrastructure[3]. Reuters[2] notes the publication attracted over 21,000 subscribers within days, and Bloomberg[4] highlights Burry’s past pattern of closing funds post-success (like 2008 after housing crash). Burry stated regulatory constraints “muzzled” him while managing money professionally[1].

:
Reddit user: Burry’s newsletter is a cash grab to fund losing short positions in NVDA and PLTR[7]. Another user: Closing his hedge fund (saying he had no pulse on markets) yet selling $379/year insights is contradictory[7]. A neutral comment: Burry may be right about the AI bubble, but timing its burst is unknown—critical for profitable trades[7]. Some users compare the newsletter to snake oil or an OnlyFans for doomer audiences[7].

Research underscores Burry’s historical credibility (2008 housing crash prediction) and the traction of his newsletter (21k+ subscribers). However, social media skepticism centers on motives (cash grab) and practicality (timing). Investment implications: Burry’s AI bubble thesis may hold long-term, but short-term investors should avoid relying solely on his newsletter—success requires both correct thesis and timing. Subscribers may value historical context, but critics warn against treating his views as actionable trade signals without independent analysis.
