Michael Burry's 'Whale Fall' Strategy: Warning of an AI Bubble While Buying the Ignored Stocks

TL;DR Michael Burry is warning that the AI trade is turning into a dot-com-style bubble — and, at the same time, quietly buying nine ignored, non-AI stocks. His thesis is a 'whale fall': while everyone stares at the whale (AI) up top, perfectly good companies have sunk to the bottom and are being left for dead at cheap prices.

The man warning about a bubble is the one hitting 'buy'

What Burry says and what he does look, at first glance, like a contradiction. With one breath he warns the AI bubble is about to burst; with the other hand he's buying more stock.

That's exactly the tension that pulled me into his latest trades. He didn't just average down on two names he already owned — he leaned in with conviction. He added two brand-new positions. He labeled one a 'high-conviction pick.' And there's one more he's still watching but won't name. This is not a guy who buys by accident. So I started not from 'let's copy him,' but from a single question: why?

The résumé of a man who called 2008

If you don't know Burry, one sentence covers it: he's the guy who looked only at the data and stood on the opposite side when everyone else said things were fine.

In the mid-2000s, when every bank, analyst, and expert insisted the housing market was healthy, Burry dug into the actual numbers, concluded it would collapse, and bet against it. When housing crashed in 2008 and nearly took the whole financial system with it, he and his investors made over $700 million. That story became the film The Big Short.

Let me be clear about the frame here. I'm not telling you to buy something because Burry did — or because anyone on the internet did. That's the worst habit in investing. What I care about is the process: looking at real numbers before you spend a single dollar. That, more than any stock pick, is what separates you from the crowd.

One phrase: 'whale fall'

Underneath everything Burry is doing right now sits one idea — the whale fall.

When a whale dies at sea, the body sinks to the ocean floor. And down there it feeds an entire ecosystem of creatures nobody noticed while they were all watching the whale swim around up top. Burry believes that's precisely what's happening in the market today.

Everyone is watching AI. Nvidia, Micron, AMD, and anything with even a whiff of an AI story. All the money and all the attention flow there. As a result, a batch of genuinely good companies now sits at the bottom — beaten down not because the business is broken, but simply because it isn't an AI stock. Those are the companies Burry is loading up on. In his own words: 'These stocks are part of the mass whale fall happening away from the main spectacle.'

He isn't waiting for the crash

Here's the part I think gets misread most. Burry isn't bracing for a crash. He has already positioned himself for what comes after it.

He's spent months warning that the AI trade is morphing into a dot-com-style bubble — too much money chasing too few stocks — and that it ends badly for the AI darlings. But while everyone argues about that, he's been quietly assembling a nine-stock portfolio of companies left for dead: beaten down, ignored, and cheap.

His own line captures the strategy best: 'Lighter-expectation stocks will float to the top as the heavy-expectation stocks see market value simply disappear.'

For context, back in May he had bought Microsoft and MSCI, was watching Salesforce, and was building positions in PayPal and Adobe. Since then he hasn't slowed down — if anything, he's leaned in harder.

Great investing rarely feels comfortable. That discomfort is what creates the mispricings value investors have exploited to beat the market for over a century. But I'll insist on one thing: don't buy because Burry buys — not even out of enthusiasm for Burry himself. Know what you own and know what it's worth. That's the whole game.
