Micron (NASDAQ:) just posted the best quarter in its history. Michael Burry is shorting it anyway.
On July 2, Burry used his Substack, Cassandra Unchained, to disclose a direct short in Micron Technology at $1,051.87 a share. His argument is blunt: the memory maker’s run has carried it into bubble territory, and the AI story papering over its history is about to meet the cycle that has always defined it.
The timing is what makes the call worth reading. That gap, between a record quarter and one of the market’s best-known bears stepping in against it, is the whole trade.
The Bubble Call
Burry’s case rests on Micron’s long record rather than the next two quarters. Over 42 years, he notes, the stock has taken 34 drawdowns of more than 30%, and it now sits further above its 200-day moving average than at any point since 1984, a stretch he says even the dot-com peak never reached.
He points to a median return on invested capital near 4% and a median return on equity around 7%, both weak against a double-digit cost of capital, and argues that one quarter in three Micron is a destroyer of capital.
To Burry, the rally runs on fear of missing out and greater-fool psychology rather than fundamentals, and the claim that high-bandwidth memory is sold out through 2026 is just the latest version of a scarcity story the sector tells every cycle. He also reads South Korea’s plan to spend more than $500 billion on chips as a warning rather than a bullish signal, on the logic that when this much capital floods an industry, real returns get harder to earn.
He shorted the shares outright rather than buy puts, which he judged too expensive for now.
The Wider Basket
The Micron short does not stand alone. Two days earlier, on the same Substack, Burry disclosed shorts against NVIDIA (NASDAQ:), Applied Materials (NASDAQ:), Caterpillar (NYSE:), Tesla (NASDAQ:), and the iShares Semiconductor ETF (NASDAQ:), tied to a call that AI-linked chip names face a correction of roughly 30%.
What complicates the simple bear label is the other half of the same post. Alongside the Micron short, Burry added to long positions in PayPal (NASDAQ:), Sprouts Farmers Market (NASDAQ:), Zoetis (NYSE:), Fannie Mae (OTC: FNMA), and Freddie Mac (OTC: FMCC).
This looks less like a bet that markets crash than a rotation out of the crowded AI trade and into cash-generative names the crowd has left behind.
The Record Quarter
Here is what the short has to work against. In its fiscal third quarter, reported June 24, Micron posted record revenue of $41.5 billion, up from $9.3 billion a year earlier, with gross margin near 86% and net income above $28 billion.
The company guided the current quarter to roughly $50 billion in revenue, and chief executive Sanjay Mehrotra tied the results to the strategic value of memory in the AI era. Micron crossed a $1 trillion market value in late May, and its multi-year supply agreements are built to make the boom look less like a spike and more like a plateau.
On the numbers alone, this is the strongest the company has ever been, which is exactly why the bulls read a re-rating where Burry reads a top.
The Cycle Question
So the trade comes down to a single question: is memory finally structural, or still cyclical? Burry has been early before, and shorting a momentum leader carries open-ended risk, since a short can bleed for a long time before a thesis pays, if it ever does.
Micron’s beta near 2.2 cuts both ways, magnifying the pullback he is counting on and any squeeze against him. The tells worth watching are HBM pricing and hyperscaler capital spending, the two readings that would confirm either durable demand or the first crack in it. Micron does not report again until late September, which leaves both sides a full quarter to be proven right.
One caveat colors the whole thing: Burry closed Scion Asset Management in late 2025 and now runs a personal book in public, so this is a conviction call, not an institutional one.
Strip away the celebrity and the argument is narrow. Burry concedes Micron is booming. His bet is that the boom is the cyclical kind, priced today as if it were permanent, and that the cycle always returns. Micron’s record quarter is the market’s answer, at least until the next one lands.
