ChangXin Memory Secures Approval for China's Largest IPO in Four Years

China's securities regulator has approved ChangXin Memory Technologies' initial public offering, clearing the path for what would be the largest listing on Shanghai's STAR Market since 2022. The Hefei-based company, China's leading manufacturer of dynamic random-access memory chips, plans to raise 29.5 billion yuan (approximately $4.4 billion USD) through the issuance of 10.6 billion shares, making it the second-largest IPO on the STAR Market overall.

The approval underscores Beijing's strategic commitment to accelerating funding for domestic semiconductor champions and strengthening China's self-sufficiency in memory chip production. ChangXin Memory is the only Chinese integrated device manufacturer to have achieved large-scale DRAM production at scale, operating three 12-inch DRAM wafer fabrication plants in Hefei and Beijing that give it the largest production capacity in China and the fourth-largest globally. The company's registration became effective on June 12, 2026.

The IPO has attracted investment from leading Chinese brokerages including China Merchants Securities and Huaan Securities, as well as from insurers through alternative investment subsidiaries and industrial funds. ChangXin Memory's extensive industrial chain extends across multiple sectors—from upstream materials, equipment, and components to downstream applications—and includes suppliers comprising more than 30 mainland-listed firms with a combined market value exceeding 3 trillion yuan.

Last year, the company purchased approximately 11.5 billion yuan worth of raw materials, including 4.3 billion yuan of chemicals, 1.4 billion yuan of photoresists, 980 million yuan of silicon wafers, 590 million yuan of electronic specialty gases, and 250 million yuan of target materials. The listing is expected to strengthen China's semiconductor self-reliance while driving coordinated growth across the entire memory chip industrial chain, amid a broader wave of multibillion-dollar technology listings globally that threatens to absorb liquidity from equity markets.
