Global memory chip producers saw their stock prices climb sharply on Monday as investors reacted to a persistent supply shortage fueled by surging demand for artificial-intelligence (AI) infrastructure. Analysts warn that the tight market conditions could last months or even years, as companies prioritize high-performance chips for AI servers.
Unprecedented Supply Constraints
Samsung co-CEO TM Roh described the shortage as “unprecedented,” echoing concerns across the industry. Memory chipmakers have shifted manufacturing capacity toward high-bandwidth memory used in AI servers, leaving other sectors—such as smartphones and USB storage—facing squeezed supply.
According to market research firm TrendForce, prices for some memory chip segments have more than doubled since February last year, drawing increased attention from investors and traders anticipating continued gains.
Stock Market Performance
Shares of leading memory companies rose significantly:
- Micron (MU.O): +2%
- Samsung (005930.KS): +7.5%
- SK Hynix (000660.KS): +3%
Smaller peers also saw gains, including Western Digital (WDC.O), Applied Digital (APLD.O), and Seagate Technology (STX.O), each rising more than 3%, while SanDisk (SNDK.O) gained about 1.5%.
Micron CEO Sanjay Mehrotra indicated last month that memory markets may remain tight beyond 2026, following a 240% share price surge in 2025. Samsung and SK Hynix also saw dramatic gains last year, more than doubling and quadrupling, respectively.
The AI-Driven Supercycle
The current market rally is widely referred to as a memory chip “supercycle”, driven by exponential growth in AI infrastructure investment. Analysts at Morningstar and J.P. Morgan predict that this cycle could continue well into 2027, suggesting that tight supply and rising prices may persist for several years.
Memory is known for its cyclical volatility, with extreme swings in pricing during downturns and upturns. However, the rapid adoption of AI technologies has created sustained demand, giving companies and investors reason to expect continued strong performance.
