CXMT surges over 500% in Shanghai debut after Asia’s biggest IPO of 2026

Chinese memory chipmaker ChangXin Memory Technologies made a blockbuster stock market debut on Monday, with shares soaring more than 500% on Shanghai's STAR Market to make the company mainland China's most valuable listed firm. The listing caps Asia's largest initial public offering of 2026 and marks a milestone in Beijing's drive to build a self-sufficient semiconductor industry.

A Record-Breaking First Day

CXMT's shares opened at 49.50 yuan, roughly 472% above the IPO price of 8.66 yuan per share, and climbed as high as 55.03 yuan during the session — a gain of 535%. The rally lifted the company's market capitalization to approximately 3.65 trillion yuan ($539 billion), surpassing state-owned banking giant Industrial and Commercial Bank of China to become the largest company listed on the Chinese mainland. The Financial Times News Corp ↘ 0.03% reported the valuation also placed CXMT ahead of Hong Kong-listed Tencent as the most valuable public Chinese company.investing+2

The Hefei-based company raised 57.92 billion yuan ($8.6 billion) in the offering — nearly double its original fundraising target of 29.5 billion yuan — after overwhelming investor demand. The IPO was the largest in the STAR Market's history and the biggest Chinese A-share semiconductor offering since SMIC listed in 2020.reuters+1

AI Demand and U.S. Restrictions Fuel Investor Appetite

CXMT is China's leading producer of dynamic random-access memory (DRAM) chips, which provide temporary data storage for smartphones, servers, and artificial intelligence systems. The company held approximately 7.7% of the global DRAM market in 2025, ranking it fourth worldwide behind Samsung Electronics, SK Hynix, and Micron Technology ↗ 5.12%.douglasresearch.substack+1

The company's revenue surged 719% year-over-year to 50.8 billion yuan in the first quarter of 2026, swinging from a net loss to a profit of 25 billion yuan. CNBC reported that CXMT's operating profit reached 35.43 billion yuan in the quarter, up from a loss of 2.83 billion yuan a year earlier, driven by booming demand for computing power and capacity expansion by major manufacturers.cnbc+1

Investor enthusiasm reflects both surging AI-related memory demand and China's urgency to develop domestic chip capabilities amid ongoing U.S. export controls.investing

Analysts See Further Upside

Nomura Holdings ↘ 0.95% said the stock could rally a further 1,239% from its IPO price as CXMT wins market share over time, according to Moneycontrol. However, not all analysts are as bullish — Morningstar has warned about the company's lack of access to extreme ultraviolet lithography equipment, which could limit its ability to produce the most advanced chips. Bloomberg noted before the listing that CXMT's valuation at IPO was roughly one-tenth that of SK Hynix, leaving room for further gains if the company continues to close the technology gap.moneycontrol+1
