Micron Technology just joined one of the most exclusive clubs in corporate America. The memory chipmaker’s shares surged as much as 19% on May 26 after UBS analyst Timothy Arcuri more than tripled his price target from $535 to $1,625, the highest among 46 analysts covering the stock.

That single-day move pushed Micron past the roughly $886.74 per share threshold needed to hit a $1 trillion market capitalization for the first time. If Arcuri’s target holds up, it implies a potential valuation of approximately $1.8 trillion within the next 12 months.

The AI memory trade gets its biggest endorsement yet

The catalyst behind Arcuri’s aggressive call is Micron’s positioning in the high-bandwidth memory market. HBM chips are a critical component in the AI accelerators that power everything from large language models to autonomous vehicle systems.

Micron has also locked in multi-year supply agreements with customers, some of which include partially fixed pricing. That’s a structural shift for a company that historically lived and died by spot market memory prices.

From commodity chipmaker to top-tier tech giant

Micron’s record close on May 26 marked its 28th record close of 2026. It was also the company’s best single-day performance since 2011. The stock’s trajectory has catapulted Micron to become the 11th-largest US public company by market capitalization, slotting in just behind Eli Lilly and ahead of Walmart.

If Micron reaches the $1,625 price target, it would enter the top seven US companies by market cap.

What this means for investors

Micron is one of only three companies in the world, alongside Samsung and SK Hynix, capable of manufacturing HBM at scale. Samsung has been aggressively investing in next-generation HBM production, and SK Hynix currently holds a leading market share in HBM3E chips. Micron’s ability to maintain or grow its share of the HBM market against well-capitalized competitors will be a key variable to watch over the next several quarters.
