Key facts
- China's CXMT saw a 466% IPO surge, producing DRAM chips.
- China reportedly developed deep-ultraviolet lithography tools, challenging ASML's monopoly.
- Global AI-linked shares, including Nvidia and South Korea's Kospi, experienced significant drops.
- Market volatility was influenced by China's semiconductor advancements and Nvidia's potential deal with OpenAI.
- Analysts suggest some market reactions were overreactions to short-term threats.
The global AI economy experienced significant volatility last week, driven by China's advancements in semiconductor technology and memory chip production. The Shanghai debut of Chinese memory chipmaker CXMT, which soared 466%, and reports of China developing its own deep-ultraviolet lithography tools, challenging ASML's monopoly, sent shockwaves through the market.
AI-linked shares, particularly chipmakers, saw substantial drops worldwide. South Korea's main index, the Kospi, fell sharply, heavily impacted by semiconductor giants SK Hynix and Samsung Electronics. In the US, the Nasdaq index entered correction territory, and Nvidia experienced a notable decline, briefly losing its position as the world's largest listed company to Apple.
However, a rebound occurred later in the week, fueled by strong financial results from Amazon and Microsoft, which helped to calm investor nerves. The Kospi jumped nearly 20%, though it still marked its worst month since October 2008.
Analysts suggest that the sell-off in memory chip stocks like SK Hynix and Micron may have been an overreaction, given the ongoing global shortage of DRAM chips, which is projected to continue until 2030. CXMT's production of DRAM chips is seen as complementary, not competitive, to GPU makers like Nvidia.
The more significant concern for Western investors stems from China's potential to develop its own lithography tools, which could eventually lead to the production of GPUs rivaling Nvidia's. However, experts believe that establishing competitive semiconductor fabrication plants will take years, and ASML's dominance outside mainland China remains structurally secure in the short term.
This week's developments are viewed as game-changing for the AI economy, largely predictable given US export controls pushing China toward domestic capabilities. Some analysts believe Chinese chip companies may eventually undercut and outcompete major chipmakers on price, similar to their impact on other industries.
