(SeaPRwire) –   Micron Technology (MU) reached a milestone on Tuesday when its market cap surpassed $700 billion for the first time. The stock advanced around 10%, trading at roughly $635, according to Dow Jones Market Data.

Micron Technology, Inc., MU

This move places Micron among an elite group. It added $132.8 billion in market value over just three trading sessions. Year to date, the stock is up 125%, contributing approximately $395 billion to its market cap in 2026 alone.

Over the past 12 months, Micron has increased by 690%.

The catalyst behind the day’s rally included analyst upgrades, a new product launch, and growing investor discussion about whether artificial intelligence has fundamentally transformed the memory chip industry.

DA Davidson began covering MU with a Buy rating and a $1,000 price target—the highest on Wall Street. Melius Research also initiated coverage with a Buy rating and a $700 target, citing strong AI-driven demand for high-bandwidth memory, DRAM, and NAND. TD Cowen raised its price target to $660 from $550.

Supply Can’t Keep Up With Demand

CEO Sanjay Mehrotra was clear about supply constraints. He noted Micron currently meets only 50% to two-thirds of key customer demand in the medium term. Data center memory is expected to surpass 50% of the total addressable market for the first time in 2026.

Major tech companies are confirming these pressures. Meta’s CFO cited higher component pricing as the main reason for raising its 2026 capital expenditure. Microsoft quantified a $25 billion impact from elevated component costs. Amazon’s CEO described memory costs as having “skyrocketed.”

Micron also announced a new product on Tuesday—the 245TB Micron 6600 ION SSD, designed for AI, cloud, and hyperscale applications. The company claims the drive requires 82% fewer racks than traditional HDD-based solutions.

Goldman Sachs observed that Micron accounts for 51% of all S&P 500 earnings revisions since the start of the recent Middle East conflict—a sign of how pivotal MU has become to the current earnings cycle.

Memory Stocks Broadly on the Move

Micron is not the only memory sector player gaining momentum. Western Digital is up 176% year to date. Seagate has gained 185%. SanDisk has jumped 477%.

Bernstein set a $1,750 price target on SanDisk. Fox Advisors raised its SanDisk target to $1,500. Both moves reflect rising NAND and DRAM pricing across the industry.

A recent IDC report suggested that AI demand could break the memory chip market’s long-standing cyclical patterns—a major concern for investors who have historically viewed memory stocks as boom-and-bust assets.

Melius analyst Ben Reitzes said plainly in late April: “It is time to acknowledge memory is core to our AI coverage.”

According to FactSet data, among 50 analysts covering Micron, the average rating is Buy, with a consensus price target of $583.83—now significantly below the current trading level.

In April, MU gained 53%. May has already seen another 24% increase.
