Michael Burry Launches Substack to Warn of AI Bubble After Deregistering Hedge Fund
Michael Burry, the famed investor best known for predicting the 2008 housing market crash, has launched a Substack newsletter to share his latest market warnings—this time focusing on the rapidly inflating artificial intelligence (A.I.) sector. The move comes after Burry officially deregistered his hedge fund, Scion Asset Management, earlier this year, marking a new chapter in his career as a market commentator.
Burry’s Substack, launched on November 23, 2025, has already attracted over 35,000 subscribers. The platform will serve as a forum for Burry to voice his bearish outlook on the A.I. market, drawing parallels to past speculative bubbles such as the dot-com boom and the housing crisis. Subscribers pay $379 annually or $39 per month for access to his insights.
In the newsletter’s description, Burry wrote, “The current market environment is contentious and running hot. Lots to talk about.” He plans to publish one to two posts per week, with occasional Q&As, videos, and guest contributions. Rather than making direct investment bets, Burry will focus on analyzing and breaking down market trends.
Burry’s warnings about the A.I. bubble have gained traction online, especially after he returned to social media in October following a two-year hiatus. In a now-viral post, he wrote: “Sometimes, we see bubbles. Sometimes, there is something to do about it. Sometimes, the only winning move is not to play.”
His latest commentary echoes concerns he raised in previous years, when he warned of bubbles in meme stocks and cryptocurrency. While some of his recent market calls have not panned out, Burry’s reputation for spotting major market shifts continues to attract attention.
In his Substack launch, Burry referenced former Federal Reserve Chair Alan Greenspan, who in 2005 dismissed the idea of a housing bubble, saying it “does not appear likely.” Burry pointed out that current Fed Chair Jerome Powell has described A.I. companies as “profitable” and “different” from previous speculative manias—a sentiment Burry finds troubling.
“I am not retired,” Burry said. “There is still nothing I enjoy more than analyzing companies and markets each and every day.”
The launch of his Substack marks a shift from active fund management to a more public-facing role as a market analyst and commentator. Burry’s new platform gives him the freedom to speak candidly about his views, unencumbered by the regulatory and operational constraints of running a hedge fund.
As the A.I. sector continues to attract massive investments and sky-high valuations, Burry’s warnings serve as a cautionary note for investors and tech enthusiasts alike. Whether his latest predictions will prove prescient remains to be seen, but his voice is once again at the center of the debate over market bubbles and speculative excess.
