Micron’s Market Value Tops $1 Trillion for the First Time as Stock Surges 18%

Micron Technology crossed a $1 trillion market value for the first time on Tuesday after its shares jumped 18%, extending a rally fueled by surging demand for artificial intelligence memory chips. The move reflected growing investor optimism that AI infrastructure spending will keep boosting the company’s earnings and valuation as memory becomes a critical bottleneck in the next phase of the AI boom.

The rally was reinforced by UBS, which nearly tripled its price target on Micron to $1,625 per share from $535. UBS pointed to the potential for long-term agreements with partially fixed pricing, arguing that the market may begin assigning Micron a more normalized valuation as structural changes from AI reshape the memory industry. The new target implies substantial upside from Friday’s close and added momentum to a stock that has already more than tripled this year.

Micron is benefiting from a broader surge in semiconductor names tied to AI. Investors are increasingly moving beyond Nvidia and into chipmakers that supply memory and central processing units needed to power agentic workloads and other compute-intensive applications. That shift has helped turn memory chips into one of the most sought-after components in the global AI supply chain. With demand running ahead of supply, chipmakers have been able to raise prices, and Micron’s major competitors, including SK Hynix and Samsung, have also moved to capitalize on the shortage.

The company’s rise has been swift. Just weeks ago, Micron moved past a $700 billion market capitalization and entered the ranks of the most valuable U.S. technology companies. Its latest milestone places it among the most prominent beneficiaries of the AI investment cycle, which has pushed capital toward companies supplying the hardware behind advanced computing systems.

The rally also highlights renewed interest in central processing units, another area drawing investor attention as AI workloads expand. Intel has staged a dramatic recovery after missing much of the early AI trade, climbing more than sixfold and trading near all-time highs. The company is in the middle of a broad turnaround and has received major support from a U.S. government investment last summer. Other chipmakers including Qualcomm, Advanced Micro Devices and Marvell Technology have also posted gains and reached new highs, underscoring how the AI trade is broadening across the semiconductor sector.

Micron’s surge reflects a market increasingly focused on the physical constraints of AI growth. As models become more complex and agentic applications demand more memory and compute power, investors are betting that suppliers of chips and related components will remain essential winners. The company’s latest valuation milestone shows how quickly the AI boom is reshaping the semiconductor landscape and elevating firms that sit at the center of the industry’s supply chain.
