Michael Burry is trading the trading desk for a keyboard, turning his market skepticism into a subscription product just as artificial intelligence euphoria hits a fever pitch. His new Substack is not a retirement hobby but a fresh platform for a familiar warning, and his opening salvo targets Nvidia at the very center of the AI boom.
I see his move as more than a branding exercise: it is an attempt to reframe how retail and professional investors think about this cycle, with Burry using his “Big Short” reputation to challenge what he views as a dangerous consensus around AI leaders.
From hedge fund manager to paid market commentator
The first shift that matters is structural, not rhetorical. Michael Burry of “The Big Short” has effectively pivoted from managing outside capital to selling his analysis directly to readers, launching a paid newsletter on Substack that he says now has his full attention. Reporting on Nov 23, 2025 describes how Michael Burry of “The Big Short” is offering access on a monthly or annual basis, turning his market calls into a subscription business rather than a fund structure.
He is explicit that this is not a retreat from markets. In his own words on Substack, Burry wrote “I am not retired,” stressing that the newsletter now has his “full attention” after he closed his hedge fund, a stance detailed in coverage dated Nov 23, 2025 that highlights how Burry explained managing money had become less appealing than publishing his research directly. That framing matters because it signals he wants influence over the debate, not just a track record.
A launch timed to the AI boom, with Nvidia in the crosshairs
The timing of the launch is not accidental. Coverage on Nov 23, 2025 notes that Burry, long known as a skeptic of market manias, is using his new platform to question the current AI surge, with one report describing how “Zoom In” on Nov 24 framed Michael Burry as a vocal critic of the AI boom who plans to share detailed findings in upcoming posts. Another summary dated Nov 23, 2025 lists as Key Points that Michael Burry launched a paid Substack newsletter on November 24, 2025, and that his debut writing criticized Nvidia, underscoring that Key Points from his launch are already circulating among investors and financial analysts.
In that first wave of posts, he goes straight at the market’s favorite AI hardware name. Reporting on Nov 23, 2025 describes how Michael Burry criticises NVIDIA and the AI boom in his new Substack, comparing today’s tech hype to the dot-com bubble and arguing that the current narrative around AI resembles earlier episodes of “glorious folly,” with one account noting that Michael Burry criticises NVIDIA and questions whether the underlying technology is as ready as the market assumes. That choice of target ensures his Substack is not just another macro diary but a direct challenge to one of the most widely held stocks in the world.
Inside Burry’s case against Nvidia and the AI trade
What Burry is building is not just a newsletter but a thesis, and Nvidia sits at the center of it. In the blog’s About section, he says the project will focus on “stocks, market and economic trends, special situations, and” other themes, and early coverage on Nov 23, 2025 notes that In the About section Burry has already targeted Nvidia, promising to post frequently and to dissect what he sees as excesses in AI valuations. That framing positions his criticism as part of a broader effort to map out where he believes the market is mispricing risk.
The specifics of his complaint go beyond a simple “too expensive” argument. Takeaways by Bloomberg AI on Nov 23, 2025 describe how Michael Burry is standing by his criticism of Nvidia Corp after the company pushed back, with the summary explaining that Takeaways from his Substack include concerns about how Nvidia Corp’s reported numbers reflect underlying demand. Another report on Nov 23, 2025 notes that Famed investor Michael Burry (Trades, Portfolio) continues to question Nvidia’s stock practices, with a detailed account of how Michael Burry Criticizes NVIDIA Stock Practices NVDA and raises issues about the sustainability of current earnings and the way equity-based incentives interact with valuation.
A public clash as Nvidia pushes back and Burry doubles down
Once Nvidia responded, the dispute moved from a one-sided critique to a public clash. Coverage summarizing the exchange explains that the company pushed back on Burry’s claims, prompting him to reiterate his concerns in a follow-up post and in other communications, with the Nov 23, 2025 Takeaways noting that Bloomberg AI highlighted his refusal to soften his stance even after Nvidia Corp defended its reporting. That kind of back-and-forth is unusual, since most large-cap companies avoid engaging directly with individual critics, and it underscores how visible his Substack has become in a matter of days.
The escalation did not stop there. On Nov 24, 2025, a separate account described how “Big Short” Michael Burry Doubles Down On Bear Case After Nvidia Pushes Back In Wall Street Note, detailing that the clash intensified after reports of his criticism circulated and that he framed certain accounting and demand signals as potentially indicative of fraud, language that appeared in a summary of how Big Short Michael Burry Doubles Down On Bear Case After Nvidia Pushes Back In Wall Street Note. By taking that step, he is not just questioning valuation but hinting at deeper structural issues, a move that raises the stakes for both his reputation and Nvidia’s.
Why Burry’s Substack matters for investors watching the AI cycle
For investors, the significance of Burry’s Substack is not only in the content but in the format and timing. Earlier this month, Burry teased on X that he would be “on to much better things” on November 25, and reporting on Nov 23, 2025 explains that Exactly where his Substa would land became clear when he launched a paywalled Substack after de-registering his hedge, with one account noting that Earlier coverage highlighted how the post getting the most attention so far lays out his view that AI spending artificially boosts earnings. That combination of a teased launch date, a paywall, and a high-profile target ensures his analysis is part of the broader conversation about whether AI is a durable growth engine or a cyclical bubble.
His track record is part of the draw. A separate summary on Nov 23, 2025 reminds readers that Michael Burry, whose uncanny ability to spot impending financial crises earned him a place in history and in the book and film “The Big Short,” has now launched a Substack and taken aim at Nvidia in his first post, with the report emphasizing that Michael Burry is again warning of a potential market bubble. When someone with that history chooses to focus his new platform on AI, Nvidia, and what he calls the “glorious folly” of the moment, it becomes a signal that the debate over this cycle’s winners and losers is only just beginning.
