Memory Chipmakers Unveil $2.1 Trillion Expansion as AI Demand Doubts Stoke 2028 Glut Fears
1 articles · Updated · Financial Times · Jul 20
Summary
$2.1 trillion in planned spending by Samsung, SK Hynix and Micron has shifted investor focus from AI-driven shortages to the risk of a memory-chip glut, knocking Samsung, SK Hynix and Micron shares down more than 30% from recent highs.
SK Hynix has pledged to double capacity within five years, while Samsung and SK Hynix together aim to double South Korea's DRam output, a buildout that could tip conventional DRam into oversupply by 2028 or 2029 if AI demand weakens.
AI demand itself is under scrutiny as investors question whether hyperscalers can sustain heavy spending; reports that Meta may sell excess computing capacity have added to concerns that the first infrastructure wave could fade.
New supply will take years to arrive and HBM remains tighter because it is harder to make, but China is the key swing factor: CXMT could reach 500,000 wafers a month by end-2028, with China seen driving about 30% of net DRam additions through 2028.

Navigating the $2 Trillion AI Memory Surge: 2026-2028 Boom, Oversupply Warning, and Long-Term Industry Impact
Overview
As of July 2026, the memory chip industry is booming due to the soaring demands of artificial intelligence infrastructure. This surge is not just a typical cycle but marks a major shift in the market, driven by the huge computational needs of AI, especially for training large language models and running complex applications. As a result, there is an insatiable demand for high-performance memory, leading to significant profit gains for major companies and creating supply constraints across the sector. Industry leaders project massive growth, with the AI chip market expected to exceed $500 billion by 2028 and the broader data center chip market reaching $1 trillion.
