CXMT Shares Surge Again as Chinese Chipmaker Gains Ground in AI Memory Market

CXMT Corp closed Friday up nearly 9 percent at 57.60 yuan, marking its fifth straight day of gains on the Shanghai Stock Exchange. This momentum has pushed its valuation to roughly 3.54 trillion yuan, or $523 billion. The chipmaker’s growth streak comes hot on the heels of its record-breaking IPO just last week.

ChangXin Memory Technologies, known as CXMT, debuted on the STAR Market on July 27. The stock soared an astonishing 466 percent on day one, momentarily outranking the Industrial and Commercial Bank of China as the most valuable mainland Chinese firm by market cap. The IPO raised around 58 billion yuan ($8.6 billion), cash CXMT plans to funnel into boosting output and closing technology gaps with international competitors amid tightening US restrictions on semiconductor tech exports to China.

How CXMT Fits Into the Global DRAM Picture

Since its founding in 2016 and headquartered in Hefei, CXMT has climbed to hold about 7.7 percent of the global DRAM market. Samsung, SK Hynix, and Micron dominate the remaining 90 percent, making CXMT the fourth-largest player. The company mainly produces standard memory chips for consumer gadgets like phones and laptops, but it’s still trailing in the advanced High Bandwidth Memory (HBM) segment vital for AI data centers. Industry insiders suggest CXMT aims to roll out HBM products domestically by 2027. Major companies including Dell, HP, and Apple have begun testing CXMT chips, attracted by lower prices, even as geopolitical tensions cast shadows. The Pentagon lists CXMT as linked to the Chinese military, a claim the company denies. Apple is reportedly lobbying US regulators to greenlight these chips for its supply chain.

This growth story unfolds as the global memory chip sector experiences a supply crunch known as “RAMageddon,” which has bolstered prices for devices like Apple’s smartphones and sparked volatility in chip stocks across markets from Seoul to Wall Street. While CXMT promises relief to the memory shortage, analysts remain divided on how much impact it will have.
