Changxin’s IPO thrust Hefei’s state capital strategy into focus as paper gains topped RMB 1 trillion
Changxin Memory’s market debut on Shanghai’s STAR Market on July 27, 2026, turned a long-running industrial bet by Hefei into one of the most discussed capital stories in China. The company opened at its RMB 8.66 offer price, surged more than 465% by the close, and finished its first day with a market capitalization of about RMB 3.3 trillion. On the following day, its valuation briefly climbed to RMB 3.66 trillion. That move sharply lifted the value of Hefei’s state-owned holdings. Based on the final ownership structure cited in the source article, Hefei’s state capital system was sitting on paper gains of more than RMB 1 trillion, built from cumulative investment of roughly RMB 26 billion to RMB 30 billion over nearly a decade. The article traces that outcome back to 2016, when Zhu Yiming pushed a DRAM industrialization plan that many places declined as too risky, while Hefei agreed to back the project. The report also links Changxin with an earlier BOE investment in 2008 to explain what is now widely called the “Hefei model”: using patient state capital to support strategically important industries through long loss-making cycles, then using the capital market to reprice those holdings. At the same time, the article argues the model is not easy to duplicate. It points to four factors behind Hefei’s result: unusual policy continuity, specialized state investment platforms, favorable timing tied to the AI-driven memory boom, and organizational discipline that many other cities have struggled to match.
