I just reviewed Michael Burry's tweets this week, and it's interesting how this guy remains relevant after all this time. He's not just the one from The Big Short, you know? His track record over the past 26 years is practically impeccable. From predicting the 2008 mortgage crisis to calling shots on Apple, oil, gold, and everything else, Burry has a record that many investors envy.

But what caught my attention was his confession about Bitcoin. In 2013, after meeting with a friend at Lightspeed, Burry was about to buy Bitcoin when the price was around $50. He thought it over, went to sleep on the idea, and ultimately didn't do it. Imagine that. If he had invested just $100 back then, he would have bought 2 BTC. Today, those 2 Bitcoins would be worth around $138,660 at the current price of $69,330 each. That’s a nearly 139,000% gain. Burry himself admits this is his biggest regret.

What’s interesting is that Burry has not been silent lately. He has been publicly questioning the massive spending on AI infrastructure by tech giants. He directly addressed Oracle, Google, Meta, Microsoft, Amazon, Nvidia, and Caterpillar, asking when this data center expansion will really end. He points out that hyperscalers are projecting combined capex of between $650 y $700 billion by 2026, consuming almost all their cash flow and forcing them into financing structures they have historically avoided.

It’s not just Burry who sees this as problematic. Man Group published an analysis in November saying that although AI is transformative, the spending might be ahead of actual adoption. The pattern is always the same in tech: initial enthusiasm, huge promises, uncontrolled spending, and then reality forces a pause.

What intrigues me is how Burry connects all this. His regret with Bitcoin, his warnings about AI, his market timing track record. The guy sees patterns where others see noise. And although he didn’t get Bitcoin right in 2013, his instinct about bubbles and excess capital remains as sharp as ever. It’s worth paying attention to where he’s looking now.
