In just 48 trading sessions, Micron Technology has doubled its market capitalization to roughly $1.2 trillion — a feat that underscores the ferocity of the artificial intelligence-driven memory boom. The stock, which has surged more than 930% over the past year, closed Wednesday at €932.20, within striking distance of its all-time high of €938.70. That 70% monthly gain and 246% year-to-date advance have left even seasoned Silicon Valley observers scrambling for superlatives.
The catalyst is a deepening shortage of high-bandwidth memory (HBM), the specialized chips that form the backbone of AI infrastructure. Micron can currently meet only 50% to 66% of customer demand for HBM, with capacity booked solid through 2027. The company’s entire HBM4 production for 2026 is already sold out, and its next-generation chips — boasting bandwidth exceeding 2.8 TB/s — are being optimized for Nvidia’s forthcoming “Vera Rubin” graphics processors. CEO Sanjay Mehrotra sees the HBM market hitting $100 billion by 2028, growing at a compound annual rate of 40%.
Wall Street has taken notice with conviction. On June 3 alone, multiple bulge-bracket banks slashed their targets upward. Susquehanna lifted its price objective from $600 to $1,750 after boosting its own stake in Micron by 206% in the first quarter of 2026 to roughly 3.63 million shares. UBS tripled its target to $1,625, up from $535, while Morgan Stanley doubled to $1,050, arguing that the memory bottleneck could persist for two to three years. JPMorgan raised its global memory market forecast to $1.7 trillion by 2028, portraying memory chips as evolving from cyclical commodities into strategic AI infrastructure assets.
This structural shift is not lost on analysts who have studied the industry up close. Raymond-James analyst Melissa Fairbanks returned from a research tour through South Korea and Taiwan — meeting with Samsung, SK Hynix, and key suppliers — convinced that the memory market has fundamentally changed. Producers are behaving more disciplined than in previous cycles, she says. Customers are signing long-term purchase agreements that provide far greater visibility than ever before. Production capacity is locked up for “multiple years,” and pricing remains stable. Fairbanks sees no demand concerns.
Should investors sell immediately? Or is it worth buying Micron?
To insulate itself from cyclical downturns, Micron has begun entering into so-called Strategic Customer Agreements. The first such multi-year contract runs for five years, designed to create predictability on both sides for HBM and other advanced memory products.
The financial results already reflect this transformation. In the first quarter of fiscal 2026, revenue hit $13.6 billion, a 56.6% jump from the prior year. For the second quarter, management guided for a record $18.7 billion. The company’s GAAP gross margin has doubled in a year to 74.4%. Earnings expectations for the third quarter — which ended in May and will be reported on June 24 — call for adjusted profit of roughly $19.29 per share, more than ten times the $1.91 earned in the same period last year. Revenue is forecast to approach $34 billion, up from just over $9 billion a year ago. In the previous quarter, Micron smashed estimates: $12.20 in adjusted earnings per share versus the $9.31 consensus.
Yet euphoria has its dissenters. Technical indicators flash overbought: the relative strength index sits at 83.1, a level that has historically preceded pullbacks. Insider selling has picked up, and competition from Samsung and SK Hynix for AI clients like Nvidia remains intense. 24/7 Wall St. has slapped a “Sell” rating on the stock with a price target of $476.66, arguing that memory cycles have always corrected sharply. The analyst consensus may be “Strong Buy,” but the average price target stands roughly 22% below the current trading price — an unusual gap that reflects not doubt about the structural shift, but astonishment at how fast the rally has outpaced forecasts.
Historical patterns also counsel caution around earnings. Micron’s biggest gains have typically occurred between report dates, not immediately after them. On June 24, the company will have to show whether the demand narrative can justify a valuation that has already priced in several years of HBM dominance. The DDR4 market offers a real-time check: spot prices for DDR4 chips rose 3.57% to $34.80 in the week through June 3, while the NAND flash market remained relatively stable. With Micron’s HBM4 bandwidth exceeding 2.8 TB/s and its entire 2026 production already sold, the only question left is whether the trillion-dollar price tag can withstand the next cyclical gust — or whether this time really is different.
