Stock market turmoil sheds stark light on the opaque AI economy

Chinese memory chipmaker CXMT's stock surged 466% on its Shanghai debut, highlighting China's advances in semiconductor technology including deep-ultraviolet lithography. This disrupted global AI chip markets, causing significant stock drops in South Korea and the US, notably impacting Nvidia and Samsung. A rebound followed after strong earnings from Amazon and Microsoft, but volatility underscored concerns over the opaque AI economy and chip supply chains.
