Chinese chipmaker CXMT surges over 470% in Shanghai debut, becomes Chinas most valuable listed firm

ChangXin Memory Technologies (CXMT), a Chinese semiconductor manufacturer, saw its shares surge by over 470% on its first day of trading on the Shanghai stock exchange, making it the most valuable listed company in China. The spectacular debut comes amid a frenzy around artificial intelligence and strong state support for the domestic chip industry.
CXMT, which was founded in 2016 and is based in Hefei, China, specializes in manufacturing memory chips for computers, servers, and smartphones. The company's initial public offering (IPO) was priced at 8.66 yuan per share, a number chosen for its cultural significance in China as it is associated with good luck and wealth. The shares opened at more than five times the IPO price, with retail investors subscribing to the shares more than 200 times the amount on offer.
The company's success is attributed to strong state support and the global shortage of chips, which has been exacerbated by the focus of major manufacturers on high-end chips for AI data centers. CXMT has filled this gap by producing affordable DRAM chips used in everyday electronic devices, including budget smartphones and laptops.
The rise of CXMT is part of a broader trend in China's tech industry, where companies are increasingly producing competitive and cost-effective alternatives to Western technology. Chinese AI startups, such as DeepSeek, Z.AI, and Moonshot AI, are developing models that match the performance of Western counterparts like OpenAI and Anthropic but at a fraction of the cost.
According to Selina Xu, China research lead for former Google CEO Eric Schmidt, Chinese startups have introduced techniques to boost efficiency, getting the most out of every unit of computing power. This has been partly driven by US restrictions on exports of cutting-edge AI chips, forcing Chinese companies to optimize their models.
The success of Chinese tech companies comes amid rising geopolitical tensions. China has accused the US of "AI hegemonism" and threatened countermeasures over potential probes into Chinese AI companies. The US has alleged that Chinese firms have copied American AI technology.
CXMT is now the fourth-largest manufacturer of memory chips worldwide.
