#TradFi交易分享挑战 Single-day surge of 19.29%! Market capitalization breaks 1 trillion! Micron MU: From a small basement factory to the AI storage king
These past few days, the US semiconductor sector has completely exploded! Storage giant Micron Technology (stock code: MU) has staged an epic surge, fully igniting the tech track.
The previous day soared 19.29%, setting a ten-year record, and last night continued to rise strongly by 3.63%, with market cap stabilizing at $1.047 trillion, not only solidifying the trillion-dollar valuation base but also surpassing Berkshire Hathaway, entering the ranks of top global tech giants! No one expected that today, a chip giant comparable to Nvidia and TSMC with a trillion-dollar valuation, was just a four-person workshop in a dental clinic basement 48 years ago. From being dismissed by the market as a “cyclical junk stock,” to becoming a sought-after “AI hard currency leader,” Micron’s turnaround reveals the most authentic wealth explosion logic in the semiconductor industry. Today, this article will thoroughly explain: Micron’s origins, core team, flagship products, technological barriers, and the truth behind stock price movements—understanding the underlying logic of this surge!
Origin: From basement startup, a pure tech obsessive
In 1978, Boise, Idaho, USA. Four engineers from Motorola quietly founded Micron Technology in a dentist’s office basement. Without top-tier capital backing or a luxurious startup team, the initial founders were only four:
✅ Ward Parkinson
✅ Joe Parkinson
✅ Dennis Wilson
✅ Doug Pitman In the early days, Micron had only one obsession: to relentlessly develop storage chips, minimizing chip size and strictly controlling costs.
The company’s first business was designing 64K DRAM chips for major industry players, gaining a foothold with smaller size and more stable performance. In the following years, Micron kept climbing:
📌 1981: Self-developed and produced 64K DRAM, officially establishing the production and sales chain
📌 1984: Launched the world’s smallest 256K DRAM, and went public on NASDAQ the same year. Amid the global storage market dominated by Japanese and Korean companies, this grassroots American small factory forcibly carved out a gap, laying the foundation for later becoming one of the top three global storage giants (Samsung, SK Hynix, Micron).
Core team: A top talent leading the company through a decade of cycles
If the first-generation founders laid the technical foundation for Micron, then current CEO Sanjay Mehrotra is the soul figure leading Micron through industry booms and busts, and into the AI era. This Indian immigrant entrepreneur is recognized as the “cycle king” in the semiconductor industry. With 30 years of deep experience in storage, he previously worked at SanDisk, witnessing multiple industry crashes and recoveries, with precise control over industry cycles. After taking over Micron in 2017, he made two key decisions that changed the company’s fate:
👉 During the winter, he strategically invested in the storage industry’s full downturn in 2022-2023, with competitors cutting capacity and layoffs, Micron bucked the trend, heavily investing in high-bandwidth memory (HBM) and expanding production.
👉 Cutting redundancies, optimizing product lines for maximum efficiency, reducing ineffective costs, and focusing on high-end AI storage tracks, completely shedding the old low-end consumer electronics storage cycle. This foresightful contrarian strategy allowed Micron to fully realize its performance during the 2025 AI explosion, shedding the “cyclical stock” label.
Flagship products: Hard currency in the AI era, the core engine of surge
Micron does not pursue diversification across sectors, focusing solely on storage for decades, with three core products: DRAM, NAND flash, and HBM high-bandwidth memory. The biggest contributor to this surge is—HBM.
✅ HBM (High Bandwidth Memory): The heart of AI computing power Ordinary memory can no longer keep up with the speed of large AI models, and HBM’s bandwidth is ten times that of traditional DRAM, making it an absolute necessity for Nvidia AI chips and high-end AI servers. The current industry situation is extremely exaggerated: demand far exceeds supply, with capacity sold out. Micron’s HBM3E and HBM4 products are already mass-produced and delivered, with all capacity booked by 2026, and shortages expected to last beyond 2027. Thanks to advanced technology, Micron ranks as the second-largest HBM manufacturer globally, holding 35% of the market share, deeply tied to top giants like Nvidia, Microsoft, and Google Cloud.
✅ DRAM: Second globally, a fundamental need for AI servers The memory used in AI servers is over five times that of regular servers. As AI models evolve, DRAM demand continues to explode. Micron’s 1-alpha advanced process has been mass-produced, offering lower power consumption and larger capacity, monopolizing North America’s high-end server DRAM market, with gross margins steadily rising.
✅ NAND Flash: Industry-leading enterprise SSD QLC NAND technology, long-term supply to top cloud providers like Amazon AWS, Microsoft Azure. As AI data centers expand, enterprise SSD demand doubles, forming Micron’s stable revenue base.
Core barriers: Triple moats that others cannot copy or catch up
With many players in the storage industry, why does Micron stand out? Relying on technology, capacity, and ecosystem three hardcore barriers.
Technical barrier: Patent protection, advanced processes Micron holds over 12k core storage patents, creating a high industry threshold. Its DRAM advanced process and HBM stacking technology are far ahead of industry averages, with HBM yield reaching 65%, well above the 50% industry average. The new generation HBM4 mass production pace is over six months ahead of competitors.
Capacity barrier: Strategic deployment during downturns, monopolizing high-end supply During the 2022 industry winter, Japanese and Korean giants shrank capacity to cut losses, while Micron invested $15 billion in HBM high-end capacity. HBM capacity construction takes about two years, and with the industry now exploding, new entrants can’t expand fast enough. Micron directly controls high-end storage pricing power.
Ecosystem barrier: Deeply binding top AI giants, irreplaceable Micron has deeply integrated with Nvidia’s H100 and H200 series AI chips, and secured long-term orders from Microsoft, Google, and Amazon, most of which are locked in for over three years. As the only domestic US storage giant, it also benefits from policy support, continuously improving its competitive landscape.
Stock price review: From cyclical outcast to trillion-dollar AI leader, this surge is never accidental but a result of cycle reversal + AI demand + capacity scarcity. Looking back over two years, Micron’s stock performance is a textbook-level comeback.
🔻 2022-2023: After the darkest winter, the post-pandemic era saw a collapse in consumer electronics demand, halving storage prices, and the industry entered a super down cycle. Micron suffered a quarterly loss of $2.31 billion, forced to cut costs and layoffs, with its stock falling to $15, labeled as a “junk cyclical stock” with little market interest.
🔺 2024: Turning point in performance, valuation recovery The explosion of AI models led to a surge in AI server demand, fully unlocking the potential of HBM and high-end DRAM. Micron’s quarterly results turned profitable, gross margin soared to 60%, and market perception changed, with valuation rapidly recovering.
🚀 May 26-27, 2026: Continuous rally, stabilizing over 1 trillion, surpassing Berkshire Hathaway Many thought the 19.29% single-day surge was the end, but Micron’s rally never stopped! Two days of epic continuous gains, market excitement reignited, with core catalysts and latest trends completely reshaping market perception. Top Wall Street investment banks strongly forecast continued rise: UBS raised Micron’s target price from $535 to $1,625, with over three times upside, making it the highest target in the US storage sector, completely reversing market valuation logic!
Demand-supply gap continues to widen: Official confirmation that HBM shortages far exceed expectations, capacity gap extends to 2027. Market cap breaks through: On May 26, it first surpassed $1 trillion; on May 27, it surged again, closing at $1.047 trillion, successfully surpassing Berkshire Hathaway ($1.034 trillion).
On that day, the US semiconductor sector collectively declined, with the Philadelphia Semiconductor Index dropping 1.36%, chip giants like Qualcomm, ARM, and Marvell falling 4%-6%, but Micron bucked the trend, rising independently in a super rally, with the leading premium fully established!
Latest market data: Opening at $955.66 on May 27, reaching a high of $956.16, closing at $928.41, a single-day increase of 3.63%, with a two-day surge exceeding 23%; currently, Micron’s year-to-date increase exceeds 225%, and nearly 8x over the past 12 months. Amid a broad semiconductor sector correction, it achieved a crushing comeback, completely shedding the cyclical stock label!
Micron’s story offers a lesson to all tech investors. Short-term performance is driven by hype, medium-term by supply and demand, long-term by technology and cycles. Betting against the industry’s bottom during downturns and realizing dividends after the AI wave arrives is the core logic behind Micron’s explosive rise.
Today’s AI track, computing power is the face, storage is the foundation. The most hardcore signal in this round: as the broader semiconductor market retreats and chip stocks generally pull back, Micron’s contrarian strength and continuous new highs indicate that the market no longer trades on sector hype but highly recognizes Micron’s exclusive scarcity and performance certainty in high-end HBM storage. As long as the trend of model iteration and AI server expansion continues, the tight supply of high-end HBM and DRAM will persist, and Micron’s growth space remains ample.
Of course, risks must also be viewed rationally.
⚠️ The cyclical nature of the storage industry has not completely disappeared;
⚠️ If AI demand underperforms expectations or competitors significantly expand capacity, there could be subsequent pullback pressure.
But undeniably: the golden age of AI storage has only just begun.
How long do you think Micron’s contrarian rally and market crushing trend can last? Is a trillion-dollar market cap just the starting point or a short-term peak? Can the super dividends of the AI storage track continue? $MU
