On May 9–11, 2026, Micron Technology completed one of the most stunning stock market runs in semiconductor history. Shares of the Idaho-based memory chipmaker closed at $746.81 on May 8 — an all-time record — before trading near $757 on May 10, lifting the company's market capitalization past $840 billion. The 52-week gain stands at approximately 709%, making MU the single most powerful performer in the S&P 100 over that span. A stock that began 2025 below $90 now sits in a tier once occupied only by the most dominant technology franchises in the world.
- MU stock closed at an all-time high of $746.81 on May 8, 2026, up 709% year-over-year; market cap exceeds $840 billion.
- Fiscal Q2 2026 revenue tripled year-over-year to $23.86B; EPS of $12.20 crushed the $9.31 consensus by 31%.
- Entire HBM4 production capacity is sold out through the end of 2026, with Q3 guidance set at $26.5B–$28B.
From Commodity to Critical Infrastructure
For decades, Micron was treated by Wall Street as a cyclical commodity producer — a company whose fortunes rose and fell predictably with the rhythm of DRAM oversupply and undersupply. That discount is being forcibly removed from the stock's valuation in real time. The driver is High Bandwidth Memory, or HBM — a specialized form of DRAM stacked vertically beside AI processors to feed petabytes of data to GPUs at speeds that standard chips cannot approach. There is no substitute, no workaround, and critically, only three companies in the world manufacture it: Micron, SK Hynix, and Samsung.
That oligopoly dynamic, colliding head-on with exponential AI infrastructure spending, has produced financial results that look more like a software platform at scale than a traditional chipmaker.
Blowout Financials Reframe the Business
Micron's fiscal second quarter of 2026, reported on March 18, set the tone for everything that followed. Revenue of $23.86 billion came in nearly 196% above the year-ago period and exceeded the Wall Street consensus of $20.0 billion by more than 19%. Adjusted earnings per share of $12.20 demolished the $9.31 estimate by 31%. Gross margin reached a company record of 74.4%, up from 36.8% just twelve months prior. GAAP earnings surged 756% year-over-year.
DRAM revenue, which represents roughly 75–79% of total company sales, reached $18.8 billion for the quarter. NAND revenue contributed an additional $5.0 billion. Fitch responded by upgrading Micron's credit rating from BBB to BBB+, citing the materially improved profitability profile and forward revenue visibility from committed AI supply contracts. Hyperscalers — Amazon, Microsoft, Google — have moved to negotiate long-term supply agreements with Micron, a structural shift from the spot-market purchasing behavior of prior cycles.
The HBM Chokepoint That Changes Everything
The central thesis behind MU's valuation rerating is the HBM supply constraint. Micron has confirmed its entire HBM production output — including the next-generation HBM4 platform — is 100% committed through the end of calendar 2026. Every unit is contracted. Every shipment has a buyer. This is not a temporary squeeze; new fabrication capacity currently under construction will not reach production until 2030 at the earliest.
Micron's HBM3E chips established a competitive moat through 30% lower power consumption per unit of bandwidth relative to competing designs. In hyperscale data centers where energy costs represent up to 40% of total operating expenses, that efficiency advantage effectively writes procurement decisions. HBM4, now entering volume production, extends the lead with 60% higher performance and 20% better energy efficiency than its predecessor.
The total addressable market for HBM is forecast to grow at roughly 40% compounded annually — from approximately $35 billion in 2025 to around $100 billion by 2028. At that scale, the HBM market alone will be larger than the entire DRAM market was in 2024.
May 9–11: The Week That Sealed the Milestone
Friday, May 9, delivered the session that crystallized how far the MU re-rating has come. Shares surged 15.49% on May 9, closing at $746.81 — the highest closing price in company history. The catalyst was a confluence of confirmations: Micron's HBM4 supply remaining fully booked through year-end, the company's unveiling of a new 245TB 6600 ION solid-state drive designed to expand AI data center storage density without increasing power draw, and a broader semiconductor sector surge that carried AMD +11.44%, Intel +13.96%, and the VanEck Semiconductor ETF (SMH) to a 52-week high at +4.90%. Nvidia closed at $215.22, less than a dollar from its own all-time record.
By May 10, Robinhood data showed MU intraday high of $794.00, with shares settling near $757. The stock's 52-week range — $79 to $747 — tells the full story of the ride.
Micron was added to the S&P 100 in March 2026, a milestone that triggers automatic institutional buying from passive index funds and structurally broadens the ownership base. At the start of 2025, Micron was not among America's 100 largest companies. Today, it ranks among the ten most valuable technology businesses in the world.
Wall Street Raises the Ceiling
Analyst price targets have been revised upward repeatedly throughout 2026. Mizuho raised its target to $740, citing AI tailwinds and what Gartner has termed "memflation" — DRAM prices projected to spike 125% in 2026 on constrained supply. Wells Fargo and TD Cowen have both cited a potential peak EPS above $55 in this cycle, a number that would make the current forward multiple appear conservative.
Full-year fiscal 2026 consensus revenue estimates have climbed toward $78.4 billion, with fiscal 2027 projections reaching $104.5 billion. The Zacks consensus for fiscal 2026 EPS has been revised upward by 80.6% in the past 30 days. Q3 2026 revenue guidance issued by management — $26.5 billion to $28 billion — would represent yet another company record and arrives ahead of the next earnings report expected around June 24.
D.A. Davidson initiated fresh coverage with a Buy rating in late April. Seeking Alpha analysis notes Micron appears deeply undervalued at 11x forward P/E despite a 190% year-over-year revenue growth rate and a 57% net income margin.
Capital Expenditure and the Long Build
Micron is spending $6.4 billion per quarter in capital expenditures to expand HBM manufacturing capacity, including breaking ground on its first New York fabrication facility. Total capex for fiscal 2026 is budgeted at $20 billion. An advanced packaging facility in Singapore is scheduled to come online in 2026, with further expansion in 2027. The structural supply constraint, however, remains intact on any meaningful investment horizon — new capacity won't affect the supply/demand balance until 2030.
The Road Ahead
The next major milestones on Micron's calendar include JEDEC industry forums on May 12–13, covering edge computing and server/cloud AI memory standards — events where management commentary often signals demand expectations for the next cycle. The J.P. Morgan Global Technology, Media and Communications Conference on May 20 features CEO Sanjay Mehrotra, who has consistently positioned AI memory demand as a multi-year structural shift rather than a single-cycle event.
Broader macro conditions add complexity to the setup. US consumer sentiment hit its lowest recorded level ever at 48.2 in early May, and Brent crude has surged 74% year-to-date to $105.5 per barrel amid renewed US–Iran tensions — variables that could pressure macro sentiment without necessarily altering the fundamental AI capex cycle that is driving Micron's revenues.
Micron's 700%-plus run over 12 months was once dismissed as irrational exuberance. With a $28 billion revenue quarter on guidance, HBM4 capacity fully committed, and the world's largest technology companies locked into multi-year memory supply agreements, the market's verdict is becoming increasingly clear: this is not a chip cycle. This is infrastructure.
