The Micron Paradox: A $840 Billion Company Trading at a Discount

Micron's market cap briefly surpassed JPMorgan at $840B, driven by AI demand for HBM chips. Revenue hit $23.9B, up 196% YoY, with supply locked through 2028.

Memory-chip maker Micron Technology has found itself in an extraordinary position — one that would have seemed impossible just two years ago. The company's market capitalization briefly eclipsed $840 billion last week, overtaking JPMorgan Chase, yet its shares still trade at just 11 times expected earnings. That valuation gap tells the story of a company caught between explosive growth and the structural constraints of its own supply chain.

A Week for the History Books

The numbers from the week ending May 8 are staggering. Micron shares surged roughly 43%, closing at €633.50 — a fresh 52-week high. The single-day jump of nearly 15% on May 5 alone added roughly $200 billion to the company's market value after Fitch Ratings upgraded Micron's creditworthiness from BBB to BBB+. The rating agency cited "materially improved profitability and near-term revenue visibility" driven by AI demand, with hyperscalers increasingly locking in multi-year supply agreements.

Retail investors have taken notice. Vanda Research data shows net buying by individual investors hit a two-year high in mid-April. The stock now sits more than 155% above its 200-day moving average, and year-to-date gains stand at 135%. Over the past twelve months, the rally has been nothing short of historic — approximately 740%.

The Supply Squeeze That Changes Everything

Behind the price action lies a fundamental shift in the memory-chip market. Micron's fiscal second quarter of 2026 delivered $23.9 billion in revenue, up 196% year-over-year and marking the fourth consecutive quarterly record. The company's guidance for the third quarter points to roughly $33.5 billion in sales with gross margins around 81%.

The driving force is high-bandwidth memory (HBM), the specialized chips essential for AI training and inference. Every bit of HBM4 production for 2026 is already spoken for under binding contracts. Customers are now signing three-to-five-year supply agreements — a structural departure from the quarterly or annual deals that once defined the industry.

CEO Sanjay Mehrotra told CNBC that key customers can only secure between half and two-thirds of their requirements due to the supply crunch. Only three companies — Micron, SK Hynix, and Samsung — produce HBM at meaningful scale. Market researcher Gartner has coined the term "memflation" to describe what it calls the most extreme pricing environment for memory chips in years.

The Long Game

The supply-demand imbalance shows no signs of easing soon. New fabrication plants in the United States and South Korea will take years to reach full capacity. Analysts don't expect equilibrium before 2028 at the earliest. Negotiations for 2027 delivery volumes are already underway, a sign that customers are planning years ahead.

The addressable HBM market is projected to grow from $35 billion in 2025 to roughly $100 billion by 2028, according to Micron's estimates. The broader global memory market is expected to expand from around $216 billion in 2025 to over $630 billion in 2026, per Gartner.

Split Talk and Analyst Targets

With the stock trading above $700, speculation about a stock split has intensified. Micron has split its shares three times in its history, most recently in 2000. No official announcement has been made, and opinions among analysts are divided. Some view a split as a logical step to broaden the investor base; others consider it largely cosmetic given that the fundamental driver remains the HBM supply squeeze.

Wall Street is scrambling to keep up. Mizuho's Vijay Rakesh raised his price target to $740 in early May — a level the stock has already exceeded. DA Davidson initiated coverage with a Street-high target of $1,000, while TD Cowen followed with a $660 target. Despite the rally, the stock's forward price-to-earnings multiple of 11 remains low compared to most AI beneficiaries.

The Other Side of the Coin

The rally carries risks. The relative strength index sits at 73.5, signaling overbought conditions that could trigger short-term profit-taking. The supply shortage that has been a blessing could eventually become a curse — when Samsung and SK Hynix bring new capacity online, margins could come under pressure.

For now, the structural argument holds. Micron reports its fiscal third-quarter results on July 1, 2026, and the bar has never been higher. The company that can't make chips fast enough is still the one everyone wants to buy.
