Micron's $47 Billion Daily Trading Frenzy Signals a Structural Shift in Memory Markets

Micron's AI DRAM modules and 196% revenue growth fuel 695% stock surge; BofA raises target to $950 amid $1.7T data-center opportunity.

For years, Micron Technology was the invisible giant of the semiconductor world—essential but overshadowed by the flashier names in computing. That era ended abruptly when the memory specialist clocked an average five-day trading volume of $47 billion, nudging even Nvidia aside as Wall Street's most actively traded stock. The chipmaker now commands a market cap north of $900 billion, closing in on the trillion-dollar threshold, and its shares are perched just beneath a fresh 52-week high of EUR 685.

The surge in investor attention mirrors a fundamental transformation inside Micron. The company's new 256-GB DDR5 RDIMM modules for AI servers began sampling on May 12, built on the 1-Gamma DRAM process and capable of 9,200 megatransfers per second. Each module consumes more than 40% less power than a two-stick 128-GB configuration—a critical advantage for hyperscalers grappling with soaring electricity bills. The strategic importance of memory was underscored by HP Inc., which reported that storage components now account for 35% of a PC's material costs, up from 15-18% just a quarter earlier.

Bank of America has doubled down on the thesis, lifting its price target from $500 to $950 while maintaining a buy rating. The revision stems from a dramatically expanded addressable market: analysts now peg the global AI data-center opportunity at $1.7 trillion by 2030, with high-bandwidth memory (HBM) alone growing into a $168 billion segment. The HBM production pipeline is already fully booked through 2026, and new capacity from fabs in Idaho and Singapore won't arrive until mid-2027 at the earliest.

The financial results support the optimism. In the second fiscal quarter, revenue exploded 196% year-over-year to $23.86 billion, lifting net income for the trailing four quarters to $24 billion on $58 billion in sales—a net margin of 41%. The current quarter is forecast to generate $33.5 billion in revenue at a non-GAAP gross margin of roughly 81%. On a YTD basis, the stock has gained 152%; over the past twelve months, the advance stands at 695%, though the relative strength index of 77 hints at an overbought condition.

Supply constraints provide a tailwind that could persist for years. An 18-day strike by more than 50,000 Samsung employees, scheduled to begin May 21, threatens to divert orders toward competitors. Separately, the SK Group warns that wafer shortages will extend through 2030. Barclays identifies Micron as the primary beneficiary of global AI infrastructure spending, which is expected to cross the trillion-dollar annual threshold. The company's confidence is reflected in a planned $25 billion in capital expenditures for fiscal 2026, mostly funneled into new cleanroom capacity.

Customer adoption is accelerating. More than 50 new AI chip designs are being integrated by AWS, Google Cloud, and Meta, creating a structural demand base that extends well beyond cyclical swings. Institutional investors are voting with their wallets: Central Asset Investments expanded its stake by nearly 600% in the most recent period. With supply unlikely to ease before late 2027 and pricing power firmly in manufacturers' hands, the memory market's old reputation as a commodity business is being rewritten.
