ChangXin Memory Technologies (CXMT), China's most closely watched homegrown memory-chip manufacturer, launched one of the country's most anticipated IPOs of 2026 last week, thrusting its founder Zhu Yiming into the national spotlight. The Shanghai offering, set to open subscriptions on Thursday, 17 July 2026, targets 29.5 billion yuan (US$4.4 billion) in fresh capital, with some analysts projecting CXMT could eventually reach a market valuation of 3 trillion yuan — placing it among China's most valuable listed technology companies.

A founder who refused a salary until profitability

Zhu Yiming reportedly pledged in 2018 not to draw a salary from CXMT until the memory-chip venture turned profitable — a milestone the company reportedly crossed last year. The listing marks the culmination of a years-long personal wager that has defined Zhu's career and underscored China's ambitions to reduce dependence on foreign memory suppliers.

Two decades of conviction: from Silicon Valley to Hefei

Long before CXMT was incorporated, Zhu was a chip designer in Silicon Valley with a blueprint and limited capital. More than two decades ago, he predicted that the gravitational centre of the global memory industry would inevitably migrate to mainland China. In emails retained by early investor Li Jun and later reproduced in a Tsinghua University alumni publication, Zhu traced the industry's historical arc — from the US to Japan, and then to South Korea — before concluding: 'It is time for China to play [a] role in this industry.'

Why it matters: the competitive backdrop

CXMT is widely regarded as China's primary challenger to dominant global memory-chip makers. The company's IPO arrives as geopolitical tensions continue to restrict Chinese firms' access to advanced semiconductor equipment and foreign DRAM supply chains. A successful listing would give CXMT the capital firepower to accelerate manufacturing capacity and narrow the technology gap with established rivals.

Investor and institutional backing

The company's early investor base includes Li Jun, who preserved Zhu's original correspondence outlining the long-term thesis for domestic memory production. CXMT's backers have also included strategic investors from Hefei, the city that has emerged as a hub for China's semiconductor ambitions. The IPO's scale — targeting one of the largest technology fundraises in recent Shanghai exchange history — signals strong institutional appetite for the domestic chip narrative.

What's next

With subscription opening imminent, market participants will watch whether retail and institutional demand pushes CXMT's valuation toward the 3 trillion yuan ceiling flagged by analysts. The company's post-listing capital deployment — particularly spending on advanced DRAM node development — will determine how quickly it can close the gap with global memory incumbents. For the broader Chinese semiconductor sector, a successful debut would validate the state-backed model of patient, long-cycle chip investment.
