CXMT surged more than 500% on its Shanghai trading debut following a massive $8.6 billion IPO, catapulting the memory-chip maker to the top of China’s stock market by valuation with a market capitalization of $539.21 billion amid severe global supply tightness.
Memory-chip maker CXMT soared on its Shanghai stock exchange debut, overtaking the Industrial and Commercial Bank of China to become the most valuable company listed in mainland China. The listing capped the rise of an upstart founded just a decade ago whose dynamic random-access memory products are sought by Apple, according to international financial reporting.
Record-Breaking Shanghai Debut and Valuation Surge
Shares of CXMT surged more than 500% during their Shanghai trading debut on Monday following Asia’s largest initial public offering of the year. The stock reached 54.65 yuan mid-session compared to its initial sale price of 8.66 yuan per share. The explosive rally lifted the chipmaker’s market capitalization to 3.65 trillion yuan, or approximately $539.21 billion, sharply up from $85.5 billion during the IPO process itself.
The company raised 57.92 billion yuan, equivalent to $8.6 billion, in the offering on the Shanghai STAR Market. This milestone marked the largest mainland Chinese semiconductor offering on record, surpassing SMIC’s $7.5 billion Shanghai share sale in 2020. The proceeds could rise to 66.61 billion yuan if an over-allotment option is fully exercised. Following the first-day surge, the company sported a market capitalization equivalent to $484 billion in opening-day figures, placing it just short of Tencent, the most valuable company listed in Hong Kong.
Liquidity Pressures and Market Speculation
Ahead of the blockbuster listing, market participants expressed mounting anxiety over potential cash drains across Chinese equities. Tim Sun, a senior researcher at HashKey Group, noted that investors anticipated the chipmaker’s valuation would rapidly exceed 1 trillion yuan, equivalent to $139 billion, drawing liquidity away from other domestic technology shares.
Once it passes 1 trillion yuan, CXMT will become a primary heavyweight in the STAR Market and semiconductor indices, forcing index funds, active funds, and sector-specific funds to reallocate toward it,
Sun explained.
This anticipated reallocation put downward pressure on sectors that previously led regional tech rallies, including memory chips, semiconductor equipment, and domestic substitution plays. Peter Alexander, founder of Z-Ben Advisors, observed that preparations for the public listing drew capital directly out of the secondary market. Analysts emphasized that the offering served as an amplifying factor for an existing correction driven by crowded positioning and high leverage within the A-share tech sector, mirroring the cash-call effects common around major public offerings.
Financial Turnaround and Surging Revenue Guidance
The public offering arrives as the memory chipmaker rides a wave of industry demand driven by artificial intelligence infrastructure and data center expansion. In its regulatory prospectus, CXMT reported that AI demand fueled its latest upswing while warning that the market could weaken if technology capital expenditures slow down or competitors flood the supply chain.
Financial forecasts released alongside the listing highlight a dramatic operational turnaround. The company expects its first-half revenue to rise more than sevenfold, reaching between 110 billion yuan and 120 billion yuan. Furthermore, CXMT projects a net profit of 66 billion yuan to 75 billion yuan, reversing a loss recorded during the same period a year earlier.
Industry Outlook Amid Severe Memory Shortages
Market analysts point to enduring supply constraints as a primary tailwind for the newly public firm. Ellie Wong, an analyst at technology research firm TrendForce, emphasized that the memory market remains tight with price increases expected to continue through the end of 2027,
adding that amid persistent supply shortages, many customers are seeking to diversify their memory supplier base, which should significantly benefit CXMT and create more business opportunities.
Counterpoint Research noted that the capital raised through the public listing will accelerate CXMT’s capacity expansion, strengthening its position in dynamic random-access memory production. At the same time, Morningstar analyst Jing Jie observed that while the company is well-positioned to capture domestic AI demand, technological gaps with established global leaders could ultimately constrain its market share in advanced memory applications.
