AI Spawns a New Trillion-Dollar Company

Micron has surpassed the $1 trillion market capitalization milestone for the first time, as the rise of agentic AI transforms HBM and DRAM memory chips into critical new pillars of the AI race.

Micron, one of the world's largest memory chipmakers, breached the $1 trillion market cap threshold for the first time on May 26. The company's stock skyrocketed 19%, propelled by insatiable AI-driven demand that shows no signs of cooling down for its core memory product lines, including DRAM and NAND Flash.

The massive rally followed an aggressive upgrade from UBS, which tripled its 12-month price target for Micron from $535 to a Street-high $1,625 per share. The investment bank noted that Micron is uniquely positioned to lock in long-term supply agreements with partially fixed pricing.

UBS suggested that the market has long undervalued Micron, but artificial intelligence is fundamentally altering the company's corporate identity.

"MU will continue to rerate higher as more details emerge about the structural changes AI has driven to the entire memory complex," the bank stated.

While memory chips were historically viewed as a highly cyclical and volatile commodity, the AI boom is reshaping the sector into a more stable, strategic growth industry. According to CNN, the newly set price target implies that Micron's stock could still more than double from its closing price on May 22.

Micron is positioned at the forefront of chipmakers capitalizing on the next phase of the AI race. Investors are aggressively pouring capital into equities tied to CPUs and memory chips—the critical hardware components required to run and process agentic AI workloads. This represents a notable shift for a sector that was previously almost entirely dominated by NVIDIA.

Unlike the initial wave of generative AI, the emergence of agentic AI demands significantly higher memory capacity to allow models to maintain deep context, handle concurrent multi-tasking, and operate in real time. Consequently, high-bandwidth memory (HBM) has emerged as one of the most vital pillars of modern AI infrastructure.

While GPUs have traditionally been the primary catalyst driving AI development, AI server clusters cannot fully leverage a GPU's processing power without an adequate supply of DRAM and HBM—even when utilizing NVIDIA’s most advanced silicon.

The surging demand has triggered a global memory chip shortage, leaving manufacturers like Micron struggling to keep pace with order volumes. This tight supply environment has allowed Micron and its chief rivals, SK Hynix and Samsung, to implement aggressive product price hikes. Driven by these tailwinds, Micron's stock has surged more than threefold since the beginning of the year.

Just weeks prior to hitting its trillion-dollar milestone, Micron had crossed the $700 billion valuation threshold to lock in its position among the most valuable tech corporations in the United States. Meanwhile, Intel—an enterprise that largely missed out on the early wave of AI—has seen its stock swell more than sixfold, trading near historic highs.

The legacy chipmaker is currently undergoing a massive restructuring effort backed by a substantial capital injection from the U.S. government last summer. Concurrently, other semiconductor heavyweights including Qualcomm, AMD, and Marvell have all rallied to fresh record highs.
