Micron Technology crossed one trillion dollars in market capitalization this week, propelled by a 19% single-session surge after UBS tripled its price target to $1,625 per share. The stock has risen from a 52-week low near $92 to an all-time high above $895 — a move that, in percentage terms, resembles the behavior of an emerging-market speculative vehicle rather than a mature industrial semiconductor company. The underlying business is genuinely strong. The valuation has left the underlying business behind.
The bull case is real, and it deserves to be stated without qualification before it is qualified. Micron’s Q2 fiscal 2026 revenue reached $23.9 billion, up 196% year-on-year. Non-GAAP gross margin expanded to roughly 69%, a level that would have been implausible for any memory manufacturer two years ago. High-bandwidth memory — the premium product that sits directly on AI accelerator chips to feed their insatiable appetite for bandwidth — is entirely sold out through 2026 under binding, multi-year contracts with hyperscalers. That is not speculative demand. It is contracted revenue. Micron has also begun volume shipments of HBM4 aligned with Nvidia’s Vera Rubin platform, positioning it competitively in the product generation that will define the next phase of AI hardware deployment.
The structural argument for a re-rating is equally substantive. Memory is no longer behaving like a commodity. The three-supplier market for HBM — Micron, SK Hynix, and Samsung — combined with the months-long process required to qualify a new supplier, creates switching costs that traditional DRAM never had. The HBM total addressable market, which Micron’s management forecasts growing from roughly $35 billion in 2025 to $100 billion by 2028, has been pulled forward by approximately two years relative to prior estimates. These are not analyst projections extrapolated from a demand curve. They are the stated commitments of the companies buying the product.
All of that is true. None of it justifies one trillion dollars.
At $1 trillion in market capitalization and consensus fiscal 2026 EPS around $58, Micron is trading at multiples that price in not only the current AI memory supercycle but the sustained execution of a near-perfect outcome over the next several years. Memory has been cyclical for as long as it has existed as an industry. The current constraints — tight wafer allocation, HBM’s diversion of capacity from standard DRAM, packaging bottlenecks — are real, but they are not permanent. Micron, SK Hynix, and Samsung combined are projected to invest more than $58 billion in fabrication capacity in fiscal 2026 alone, more than the entire industry spent in 2023. That capital does not disappear. It converts into supply. When it does, the pricing environment that has produced 74% gross margins will face the same pressure it always has.
The more durable question is what Micron is worth when the cycle normalizes at a structurally higher floor — meaning a company that retains some portion of its premium positioning through HBM contracts and oligopoly dynamics, but no longer benefits from the acute supply shortage that compressed margins in both directions for the past decade. A market capitalization in the range of $750 billion accounts for that scenario. It reflects a business that generates meaningfully superior margins compared to its historical average, commands a durable position in AI memory infrastructure, and grows through the back half of this decade as agentic AI workloads drive continued increases in DRAM content per server. It does not price in the assumption that the current quarter extrapolates indefinitely into the future.
One trillion dollars requires something closer to perpetual scarcity. That is a faith-based valuation, and the memory industry has a long record of punishing faith-based valuations.
Micron is a well-run company in the right place at the right time. The stock is priced for a world where the right time never ends.
