Changxin Memory Technologies (CXMT), China's state-backed DRAM manufacturer, significantly expands production capacity, disrupting global memory semiconductor market pricing.
The global memory semiconductor market, buoyed by the artificial intelligence boom, now faces intensifying competition from Chinese players. ChangXin Memory Technologies (CXMT), China's largest DRAM manufacturer, is accelerating factory expansions funded by its recent initial public offering, challenging the long-standing dominance of Samsung Electronics, SK Hynix, and U.S.-based Micron. While Samsung and SK Hynix maintain technological advantages in advanced segments like high-bandwidth memory (HBM), analysts warn that the rapid growth of Chinese semiconductor firms could become a long-term burden on memory companies' performance and valuations.
According to Reuters and other outlets reporting on August 3, CXMT is pushing to build a 12-inch DRAM production plant in Beijing, with discussions underway with the Beijing Economic-Technological Development Area to secure investment funds. Once all planned new factories become operational, the company's production capacity could more than double. Samsung, SK Hynix, and Micron currently hold approximately 90% of the global DRAM market; however, analysts caution that CXMT's expansion, backed by Chinese government support, could intensify supply competition over the medium to long term.
According to market research firm Counterpoint Research, CXMT's DRAM market share rose from 3% in the first quarter of last year to 8% in the first quarter of this year, making it the world's fourth-largest player. U.S. investment journal Barron's reported that CXMT's aggressive capacity expansion, funded by its recent Shanghai Stock Exchange listing, could increase competitive pressure on existing memory firms. Although CXMT still lags behind Samsung and SK Hynix in technology, its rapid growth, fueled by government support, has dampened investor sentiment.
Some analysts, however, contend that CXMT's expansion is unlikely to immediately reshape the HBM market or threaten established players. Roh Geun-chang, a researcher at Hyundai Motor Securities, observed that "TSMC and the three major memory semiconductor companies are making large-scale equipment investments, which could make it difficult for CXMT to secure foreign-made equipment." As global semiconductor firms intensify competition for advanced equipment and U.S. export restrictions on semiconductor sales to China tighten, CXMT's expansion pace may slow more than expected.
The Guardian recently cited rapid growth in China's semiconductor industry as a factor behind the sharp correction in global AI semiconductor stocks. Following CXMT's 466% surge on its first trading day on the Shanghai Stock Exchange, progress in deep ultraviolet (DUV) lithography technology further weakened investor sentiment. The Guardian noted that South Korea's stock market, which carries heavy weightings in Samsung and SK Hynix, was hit harder than others as AI-related stocks adjusted globally, with investors taking profits as a new competitive variable—China—emerged to challenge the technological superiority that had supported high valuations in the AI semiconductor sector.
Nevertheless, some observers view China's push as unlikely to immediately resolve global memory shortages or shift HBM market dynamics. While Samsung and SK Hynix continue to lead in advanced memory products like HBM for AI servers, CXMT is focused on expanding its share in general-purpose DRAM. Kim Dong-won, a researcher at KB Securities, noted that "the fulfillment rate for memory and AI substrate demand from big tech customers remains at only 60%," projecting that memory shortages will gradually ease only after 2029.
