Example 1: How do you identify a bubble?

Michael Burry ❯  Look for the cardinal sign: supply-side gluttony. When an entire industry commits to catastrophic overbuilding — when companies are pledging trillions with nowhere near enough demand to justify it — that's your warning.

              In 2000, the dot-com sector was doing exactly this with fiber optic cables. In 2025, the AI sector is doing it with data centers and microchips.

              I called it "supply-side gluttony" in my Cassandra Unchained Substack. The internet bubble was driven by profitable companies — Microsoft, Intel, Cisco, Dell — and it still crashed because of oversupply. Today we have OpenAI, Google, Microsoft, Amazon, Oracle all committing over a trillion dollars. And at the center of it is Nvidia — the Cisco of this cycle.

              If you want to identify a bubble, don't look at valuation multiples first. Look at the supply pipeline. If the capital expenditure commitments can't possibly be justified by future demand, you're looking at a bubble.
