Micron Reaches $1 Trillion Market Value as Memory Chip Demand Rises

Micron reached a $1 trillion market capitalization this week. Samsung crossed the same threshold earlier in the month, and SK Hynix followed on Tuesday. The three companies now control most global DRAM production. In the early 1990s more than 20 firms competed in the segment.

Samsung reported more than $30 billion in profit for the first quarter. UBS analysts stated this week that multi-year volume and pricing agreements with cloud providers could keep the DRAM market undersupplied into 2028. Modern AI systems require large amounts of high-bandwidth memory for data movement inside data centers.

Lightmatter CEO Nick Harris said photonics technology does not remove the memory bottleneck.

Suppliers and locked-in contracts may reduce the historic pattern of overproduction followed by price collapses. UBS estimates the current supply constraints could extend through 2028. Investors are assessing whether these structural shifts will produce a longer cycle than past memory upswings.
