According to Business Insider, Michael Burry of “The Big Short” fame has launched a paywalled Substack blog called “Cassandra Unchained” that’s now his “sole focus.” The blog promises subscribers a “front row seat to his analytical efforts and projections for stocks, markets, and bubbles.” Burry has published two initial posts, including one titled “The Cardinal Sign of a Bubble: Supply-Side Gluttony” that directly targets the AI boom. He specifically compares Nvidia to Cisco during the dot-com bubble, noting Cisco plunged 78% during that crash. This comes after Burry recently terminated Scion Asset Management’s SEC registration and closed his hedge fund to outside cash.
Burry’s Bubble Warning
Here’s the thing about Burry’s analysis – he’s not just saying “AI is a bubble” like everyone else. He’s making a much more specific historical comparison that’s actually pretty compelling. He points out that during the dot-com bubble, people forget there were highly profitable companies driving the Nasdaq – Microsoft, Intel, Dell, and Cisco. Sound familiar? Basically, he’s saying today’s argument that “this time is different because the companies are profitable” completely ignores that the dot-com bubble had profitable giants too.
And his Cisco-Nvidia comparison is particularly brutal when you think about it. Cisco was the infrastructure provider everyone needed during the internet boom – the “picks and shovels” play. Now Nvidia occupies that exact same position for AI. But here’s the question: does that mean the same fate awaits Nvidia? Burry seems to think the patterns are “remarkably timeless.”
From Hedge Fund to Substack
So why is Burry pivoting to a paid newsletter after making hundreds of millions in the markets? It’s actually a fascinating career shift. He’s basically monetizing his reputation and analysis directly rather than through fund management fees. At $180 annually for subscriptions to his Substack, he doesn’t need many subscribers to replace his former income.
Look, the timing is pretty strategic too. He’s launching right when everyone’s wondering if AI is peaking. He’s positioning himself as the voice of reason amid the hype. And given his track record with the housing bubble, people will pay attention. Whether they’ll listen is another question entirely – hence the “Cassandra” nickname.
Supply Side Reality Check
Burry’s main argument centers on what he calls “supply-side gluttony.” He says the dot-com bubble wasn’t just about overvalued stocks – it was about “catastrophically overbuilt supply and nowhere near enough demand.” And he thinks we’re seeing the exact same pattern now with AI infrastructure.
Think about it: every major tech company is building out massive AI capabilities. Microsoft, Google, Meta, Amazon, Oracle – they’re all pouring billions into AI. But is there enough real demand to justify all this supply? Burry’s betting there isn’t. He sees the same “expansive vision” that characterized Cisco’s downfall now playing out with Nvidia and the AI ecosystem.
What This Means for Tech
If Burry’s right, we could be looking at a significant correction in the tech sector. The comparison to Cisco’s 78% plunge should make any Nvidia investor nervous. But here’s the counter-argument: maybe this time really is different. AI adoption is happening faster than internet adoption did, and the use cases seem more immediately valuable to businesses.
Still, when someone with Burry’s track record makes this specific of a historical comparison, it’s worth paying attention. He’s not just shouting “bubble” – he’s pointing to concrete patterns from the last major tech mania. Whether he’s early, wrong, or prescient remains to be seen. But one thing’s for sure: he’s definitely not trying to be the most popular guy in the room.
