Chinese chipmaker CXMT surges 466% on debut, rattling Western AI dominance

Chinese memory chipmaker CXMT soared to a 3.3 trillion yuan (£365bn) valuation on its Shanghai stock exchange debut Monday, surging 466% in its first trading day. The volatile move underscores growing investor uncertainty about the AI supply chain and challenges to Western chipmaker dominance in a sector critical to AI infrastructure.

Why it matters: Chipmakers are foundational to AI development and deployment; geopolitical shifts in chip manufacturing capacity and capability directly impact which companies and nations control the AI economy.
