Burry’s Cassandra Unchained hits 300,000 subscribers, sparking revenue speculation
With 300,000 subscribers and a $39 monthly fee, Michael Burry’s newsletter has become a financial phenomenon, though actual paid conversion rates remain undisclosed.
Michael Burry’s Substack newsletter, Cassandra Unchained, has surpassed 300,000 subscribers since its launch in November 2025, marking a significant shift from his previous role as a hedge fund manager. Burry, who gained global recognition for predicting the 2008 subprime mortgage crisis, deregistered his Scion Asset Management hedge fund with the US Securities and Exchange Commission to focus exclusively on the publication. The newsletter charges $39 per month and presents a bearish thesis regarding artificial intelligence and specific technology stocks, including Nvidia, Palantir, and Tesla.
The milestone has generated substantial speculation regarding the publication’s revenue potential. At the current subscription rate, if all 300,000 subscribers were paying, the newsletter could theoretically generate approximately $113 million annually. However, the publication also offers a free tier, and Substack does not disclose the exact number of paid subscribers. The newsletter holds a Substack "Bestseller badge" and is ranked number two in the platform’s finance category, indicating a significant base of paying users, though analysts note that the theoretical maximum revenue is likely an overestimate.
Market commentators have highlighted the stability of this income stream compared to traditional trading. The Street reported that while the exact number of paying subscribers is unknowable, the newsletter provides a steadier income than Burry’s trading positions, which have fluctuated between losses and wins. A December 2025 report from Fintech Growth Insider estimated that even a modest conversion rate from earlier subscriber numbers could generate millions annually, suggesting the venture offers a reliable revenue source independent of market volatility.
Burry’s content focuses heavily on criticism of Nvidia’s stock-based compensation, hyperscaler spending, and accounting practices. He has made trade disclosures including bearish positions on Nvidia, Palantir, Applied Materials, the iShares Semiconductor ETF, and Tesla. The Street described the subscription as buying "a front-row seat to a brilliant, deeply bearish mind," cautioning that it does not guarantee investment success but rather offers a perspective on market risks.
In a recent post, Burry stated he is "stunned and humbled" by the community growth less than eight months into the venture. The newsletter’s success coincides with broader market skepticism about artificial intelligence valuations, with other financial figures warning of potential overheating in the tech sector. The publication’s ability to attract a large audience suggests a strong demand for alternative viewpoints on the current market landscape.
