In-depth Analysis of the Storage Chip Industry: Western Digital, SanDisk, Micron Technology, Samsung, SK Hynix, DRAM Investment Logic

I. Industry Overview and Strategic Positioning

By 2026, the global storage chip industry will enter a 'super boom cycle' driven by the explosive demand for AI computing power. According to the latest data from TrendForce, the global DRAM market revenue is expected to skyrocket by 81% quarter-on-quarter in Q1 2026, reaching $97 billion. The demand for high-bandwidth storage chips in AI data centers is surging, completely reshaping the competitive landscape and rules of the storage chip industry.

Industry Landscape Characteristics:

  • The three DRAM giants' monopoly: Samsung $SAMSUNG , Micron $MU , and SK Hynix collectively control about 90% of the global market share (40.5%, 19.9%, and 29.6% respectively)

  • NAND Flash market: Samsung, SK Hynix, Kioxia, Western Digital, and Micron collectively control 63.1% of the market share

  • Market cap breakthrough: In May 2026, Samsung, #美光 , and SK Hynix all entered the trillion-dollar market cap club

Two, Core buy logic

1. AI computing power demand explosion drives a super cycle

AI infrastructure development has led to a surge in demand for storage chips, while major manufacturers have cut ordinary NAND capacity in favor of higher-margin HBM products, creating a serious supply-demand imbalance. The global DRAM revenue is expected to soar to $418.6 billion in 2026, a 177% year-on-year increase. Behind this number is a complete reshaping of the memory chip industry driven by the generative AI wave.

2. Prices are skyrocketing, profit elasticity is enormous

In Q1 2026, global storage chip prices doubled quarter-on-quarter. DRAM contract prices are rising rapidly, pushing the market into a booming cycle of supply shortages. Counterpoint Research predicts that DRAM prices will increase by 50% quarter-on-quarter in Q2 2026, and the annual market size will triple.

3. Accelerated technological iteration, deepening moats

HBM4 technology is about to be mass-produced, and the demand for high-bandwidth storage from high-end AI chips is showing exponential growth. Samsung, Micron, and SK Hynix's competition in HBM technology is becoming increasingly fierce, and the technological leader will gain higher pricing power and market share.
