The CXMT IPO on July 27 vaulted ChangXin Memory Technologies into a global DRAM peer and triggered a sell-off in Micron (MU), SanDisk (SNDK), and SK Hynix (SKHY) as investors reassessed future DRAM supply and pricing.
CXMT Debut and Scale
ChangXin Memory Technologies completed its Shanghai STAR Market listing on July 27, selling about 6.7 billion shares before any overallotment. The base proceeds totaled roughly $8.6 billion, rising to nearly $9.8 billion if the 15% overallotment is exercised, according to the IPO prospectus and listing documents. The offering implied a valuation near $85 billion.
Shares opened around 49 yuan, surged to an intraday high near 54.7 yuan, and closed close to 49 yuan—about 466% above the offer price. Turnover exceeded 140 billion yuan, and CXMT’s market capitalization briefly reached between 3.3 trillion and 3.65 trillion yuan, making it the most valuable mainland-listed company, surpassing Industrial and Commercial Bank of China.
Business Profile and Market Impact
Founded around 2016, partly through acquiring intellectual property from Qimonda, CXMT is now China’s largest DRAM producer and the world’s fourth-largest DRAM maker. It held an estimated 7.7–9.0% of global DRAM bit volume in 2025 and generated about 97% of its 2025 sales from Greater China.
The IPO proceeds are earmarked for expanding next-generation DDR5 and high-bandwidth memory (HBM) capacity. Industry commentary cites capacity targets of roughly 300,000 to 380,000 wafers per month by the end of 2026, aiming to approach incumbent levels.
The listing prompted immediate sell-offs in Micron, SanDisk, and SK Hynix, reflecting investor concerns about state-backed capacity additions eroding pricing power, capital rotation away from incumbents, and medium-term margin pressure from new Chinese scale.
TrendForce data show DRAM contract prices rose 58.0–63.0% quarter-over-quarter in Q2 2026 after nearly doubling in Q1 and are forecast to increase another 13.0–18.0% in Q3. NAND contract prices jumped 70.0–75.0% in Q2 and are expected to rise 10.0–15.0% in Q3. This pricing environment makes incremental capacity a significant risk to sustaining the recent upcycle.
Investors will watch whether CXMT converts the fundraising into planned DDR5 and HBM wafer capacity and how quickly it scales output. These developments will influence whether recent memory-price gains persist or give way to renewed margin pressure for incumbents.
