China’s Rapid Chipmaking Expansion Threatens AI Memory Chip Boom, Samsung Adviser Warns

Why It Matters

The surge in Chinese capacity threatens South Korea’s market share and could dampen AI‑related memory demand, reshaping pricing and supply dynamics globally.

Key Takeaways

• Chinese chipmakers aim to add 300,000 wafers in three years
• Their NAND share is ~20%; DRAM share could reach 12‑13%
• CXMT Q1 revenue hit $7.4 bn, up 719% YoY
• Forecasted 2026 DRAM revenue $15‑17 bn as prices rise
• Potential 2028 AI spending slowdown could curb memory demand

Pulse Analysis

The memory‑chip market has been the engine of the broader AI super‑cycle, with South Korean giants Samsung and SK Hynix riding a wave of soaring demand from data‑center operators. However, the rapid scaling of Chinese manufacturers, backed by state subsidies and lower labor costs, is reshaping the competitive landscape. By adding 300,000 wafers in the next three years, Chinese firms aim to lift their DRAM share to roughly 12‑13%, challenging the historic dominance of Korean players and potentially compressing margins as supply tightens.

Financial data underscores the intensity of China’s push. ChangXin Memory Technologies (CXMT) posted a staggering 719% year‑over‑year revenue jump to $7.4 bn in Q1, and it now forecasts $15‑17 bn in DRAM sales for the first half of 2026 as DRAM prices climb. This growth is fueled by aggressive capacity investments and a strategic focus on high‑density NAND and DRAM products that cater to AI workloads. The influx of Chinese output is expected to increase global supply, which could moderate price spikes but also erode the premium that Korean firms have enjoyed.

Looking ahead, the sector faces a dual headwind. Big‑tech firms, whose capex currently fuels memory demand, may curb spending by 2028 as returns on AI investments wane, potentially slowing the super‑cycle. Simultaneously, Samsung confronts internal labor unrest, with a planned strike by up to 50,000 workers that could shave 2‑4% off global NAND and DRAM supply. Together, these factors create a volatile outlook where market share battles, shifting AI hardware architectures, and labor dynamics will dictate the next phase of memory‑chip economics.
