Micron Technology (MU) is having the kind of rally that can shift the perception of an entire industry on Wall Street.
The memory-chip maker briefly topped the $1 trillion market value threshold for the first time on May 26, on the back of soaring demand for chips that power artificial intelligence data centers.
But the rally did not stop there.
Shares of Micron are lately trading at $928.41 for a market value of over $1.06 trillion, Bloomberg Television confirmed.
That’s a big change for a firm often seen as one of the more cyclical brands in semiconductors.
For years Micron’s fortunes soared and fell with memory chip pricing cycles. Now investors are wagering that artificial intelligence has transformed the industry in a more lasting way.
The impetus was Wall Street, Washington, and an emerging AI memory shortage.
UBS analyst Timothy Arcuri boosted his Micron price target to $1,625 from $535, CNBC indicated. This was the biggest increase among the 46 brokerages monitoring the stock.
President Donald Trump also praised Micron’s plans for investing in the U.S. at a recent rally in Suffern, N.Y., according to Business Insider, giving the company a political tailwind as investors look toward domestic chip production.
“Micron, boy Micron’s great, they’re investing hundreds of billions,” Trump said.
Micron’s AI memory boom is changing the stock story
Micron is no longer being viewed as a typical memory-chip stock.
Artificial intelligence servers need massive quantities of next-generation memory like double-data-rate and high-bandwidth memory solutions. That has put Micron, SK Hynix, and Samsung Electronics at the center of the AI infrastructure trade.
Micron has sold out its high-bandwidth memory supply for 2026 and has started development of next-generation HBM4 devices, Reuters reported.

That’s important because investors want to see evidence that the current memory cycle is not like earlier booms.
The memory chip business has historically seen bouts of oversupply, sliding prices and dramatic reversals in earnings. This time, Wall Street is predicting demand for AI might keep supplies tight for longer than usual.
The broader market is beginning to price in that notion.
SK Hynix became the latest memory chipmaker to surpass 1 trillion won ($729 million) in market capitalization, CNBC noted. The company joins Samsung and Micron, with the industry being fueled by demand for memory for AI-related.
Memory chip prices doubled in the first quarter and could jump as high as 63% in the second quarter, according to Reuters.
The sector rise is a sign of how rapidly investors have moved past seeing only Nvidia as the clear AI victor.
Graphics processors are still at the heart of the AI buildout, but data centers still need memory to store and move information quickly. That has made Micron more significant in the artificial intelligence supply chain.
Micron’s story on U.S. manufacturing adds another depth to the rise.
The company said May 22 that it started manufacturing 1-alpha DRAM at its Manassas, Va., fab, calling it the most advanced memory technology ever produced in the United States.
UBS sees Micron stock climbing even higher
The UBS price target offered investors a concrete number to focus on.
Arcuri’s $1,625 target implies significant upside even after Micron’s historic rally. His argument rests on the idea that artificial intelligence has structurally changed the memory market.

A crucial part of that theory is the greater usage of long-term supply agreements.
Such purchases may provide memory-chip makers better information on price than they have had in previous cycles. That would make Micron’s earnings stream look less volatile and thus justify a higher value multiple.
That is the key debate facing investors presently.
Micron still has the baggage of being a cyclical memory business, but the market is starting to treat it more like a winner in AI infrastructure.
That is the point that the comparison with SK Hynix highlights.
SK Hynix shares rose 9.3% on May 27, according to CNBC. The increase came as the larger Korean market rose over memory-chip stocks linked to AI demand.
Samsung also continues to be part of the tale.
Samsung and its unions have negotiated a tentative wage accord, helping to avert a potentially damaging strike at a critical time for the memory-chip industry, Reuters reported.
Micron stock rally timeline
- May 22: Micron says it started producing 1-alpha DRAM at its Manassas, Va., fab.
- May 26: Micron briefly crosses $1 trillion in market value for the first time.
- May 26: UBS raises its Micron price target to $1,625 from $535.
- May 27: SK Hynix joins Samsung and Micron in the trillion-dollar memory-chip club.
- June 24: Micron is scheduled to report fiscal third-quarter results.
Micron’s next test is already scheduled.
The company said May 27 it will host its fiscal third-quarter earnings conference call June 24 at 2:30 p.m. Mountain Standard Time.
That report could be a litmus test of whether the stock’s trillion-dollar valuation is a new baseline or a red flag.
Investors will be searching for more information on high-bandwidth memory demand, pricing power, capital spending and the long-term supply agreements noted by UBS.
The risk is expectations are moving very quickly.
Shares of Micron have more than quadrupled in the past year. That kind of rise leaves little space for disappointment if AI spend cools or memory prices drop or clients push back on longer-term contracts.
But Wall Street is delivering a clear message for now.
Micron is more than a cyclical memory-chip manufacturer with a temporary pricing snapback. It is being recognized as one of the key vendors behind the AI infrastructure growth.
