Micron approaches $1T market value as UBS triples price target to $1,625

Micron Technology just joined one of the most exclusive clubs in global finance. The memory chipmaker’s market capitalization briefly surpassed $1 trillion on May 26, making it the latest semiconductor company to cross that psychological threshold.

The catalyst was a jaw-dropping price target revision from UBS analyst Timothy Arcuri, who tripled his estimate from $535 to $1,625 per share. That’s now the highest price target for Micron on all of Wall Street, and it implies the company could eventually command a valuation approaching $1.8 trillion.

What drove the surge

Micron shares climbed as much as 19% during intraday trading, reaching approximately $891 before settling at a record close of around $880. For context, the stock had closed the previous session near $751, meaning UBS’s new target suggests more than 100% upside from that level.

UBS pointed to structural transformations in the memory market. Long-term supply agreements and surging demand for high-bandwidth memory, known as HBM, have fundamentally changed how Micron’s business operates. Companies building AI data centers are locking in multi-year contracts for Micron’s most advanced chips, giving the company revenue visibility that memory makers historically never had.

Micron’s HBM production capacity is fully booked through the end of 2026. Recent quarterly revenues from HBM alone approached $2 billion.

The trillion-dollar context

The journey here has been powered almost entirely by AI infrastructure spending. As large language models and other AI workloads demand exponentially more memory bandwidth, HBM has become the critical bottleneck. Micron has positioned itself as one of only three companies on the planet capable of manufacturing it at scale.

The other two are Samsung and SK Hynix, both South Korean giants that are accelerating their HBM4 product timelines. Samsung has been working to close the technology gap after falling behind SK Hynix in earlier HBM generations, while SK Hynix has leveraged its first-mover advantage to secure key supply deals with Nvidia.

What this means for investors

UBS’s thesis rests on the idea that structural changes in the memory industry, specifically the shift toward long-term contracts and AI-driven demand, justify valuing Micron more like a high-growth technology platform than a cyclical chipmaker. If that framework holds, a $1.8 trillion valuation within the next year is the logical conclusion.

The risk is competition. Samsung and SK Hynix are accelerating their HBM4 development, and any breakthrough in yield rates or packaging technology could shift market share dynamics quickly. Companies like Microsoft, Google, and Meta have committed billions to data center buildouts, but those capital expenditure cycles can slow if revenue from AI products doesn’t materialize fast enough to justify the spending.
