Michael Burry, the investor best known for predicting the 2008 financial crisis, has launched his own Substack, surprising followers who had been waiting for a cryptic announcement he had teased for 25 November. The page went live earlier than expected, featuring two initial posts outlining his focus on market analysis, historical patterns and financial risk.

The new platform, titled Cassandra Unchained, signals Burry’s intention to publish independent research and commentary directly to readers. The move follows months of heightened attention on his market positioning, particularly after he disclosed a series of high-profile bearish bets against companies tied to the AI boom.

Earlier this year, regulatory filings from Scion Asset Management — the investment firm Burry founded — revealed put positions against Nvidia and Palantir, both major beneficiaries of the rapid expansion of artificial intelligence. The filings drew significant interest given the scale of AI-driven market gains and Burry’s long-standing reputation for contrarian calls.

However, shortly after the disclosure, Burry deregistered Scion Asset Management as an investment adviser. He later clarified that he continues to trade, but now manages only his personal capital. The launch of his Substack marks his first structured public-facing platform since stepping away from institutional oversight, allowing him more freedom to comment on markets without managing external funds.

Burry has been particularly vocal in recent months about what he sees as emerging risks in the tech sector. He has criticised hyperscale cloud operators for what he alleges are accounting practices that artificially boost reported earnings by extending depreciation schedules for equipment. His comments come at a time when investors are increasingly debating whether parts of the technology sector have entered bubble territory.

The new publication suggests Burry intends to broaden these themes, drawing connections between present-day market behaviour and historical financial cycles. Given his history of detailed macroeconomic analysis, the platform is likely to attract investors interested in long-form commentary outside the constraints of social media.

The timing of the Substack launch also comes during a period of volatility across global markets. Concerns over interest rates, geopolitical tension and sector-specific risks — particularly in technology — have contributed to sharper swings in investor sentiment. Burry’s independent research may add another influential voice to the ongoing debate about valuations, systemic vulnerabilities and speculative excess.

While the early launch may not constitute the dramatic surprise some followers were expecting, it signals Burry’s return to regular public commentary — likely to be closely watched by investors given his track record.
