China’s Memory Chipmakers Challenge Global Giants as AI Boom Accelerates

The global race to supply artificial intelligence infrastructure is creating new winners in the semiconductor industry, and China’s memory chipmakers are increasingly positioning themselves as major contenders.

According to Jefferies’ latest GREED & Fear report, China’s top NAND flash producer Yangtze Memory Technologies Corp (YMTC) and leading DRAM manufacturer ChangXin Memory Technologies (CXMT) are moving ahead with public listings while benefiting from soaring demand for AI-related memory chips.

Their rapid expansion is not only attracting investor attention but also raising questions about how much market share Chinese companies could capture from established global semiconductor giants.

Why Are YMTC and CXMT in the Spotlight?

Both companies are preparing for major stock market listings at a time when investor enthusiasm for AI infrastructure remains strong.

Jefferies noted that YMTC has already initiated its mainland A-share listing process and could submit a formal application as early as mid-June.

The report said YMTC's revenue "exceeded Rmb20bn in the first quarter, more than doubling from a year earlier," while its NAND flash production represented more than 10 per cent of global output.

The company has also made significant gains in market share. According to Jefferies, YMTC captured 13 per cent of the global NAND flash market in the first quarter of 2026, placing it alongside some of the world's leading producers.

Meanwhile, CXMT is also moving forward with its listing plans after receiving approval for its IPO application on the Shanghai Stock Exchange's STAR Market.

How Big Is CXMT’s Planned IPO?

The proposed fundraising effort is among the largest in China's technology sector.

Jefferies said, "The company plans to raise Rmb29.5bn (US$4.36bn), which will be the second-largest IPO in the STAR Market after China foundry Semiconductor Manufacturing International Corporation (SMIC) in July 2020."

The brokerage believes the company's growth has been driven by surging demand for AI-related technologies.

"The company, according to the prospectus, expects revenue in the first half of this year to reach Rmb110-120bn marking growth of over 600% YoY," the report said.

Jefferies added that first-half net profit is expected to reach between RMB 66 billion and RMB 75 billion, a dramatic turnaround from a net loss during the same period last year.

Why Are These IPOs Happening Now?

The timing appears closely linked to the AI investment cycle.

Jefferies said, "Meanwhile, the two pending Chinese IPOs are clearly timed to take advantage of the AI capex boom to raise capital while semiconductor stocks are still hot. And that capital will doubtless be used to increase capacity."

In other words, both companies are seeking to capitalize on strong investor appetite for AI-linked businesses while securing funds to expand manufacturing capabilities.

What Message Do These Listings Send to Global Investors?

According to Jefferies, the significance of these IPOs extends beyond fundraising.

The brokerage argued that the listings could alter perceptions about China's competitiveness in the semiconductor industry.

"As for the impact of these listings from the standpoint of general investor sentiment, they will send the general message that the Chinese are coming in both the NAND flash and DRAM segments," Jefferies said.

The report suggested that investors should not underestimate China's ability to gain market share, pointing to similar developments in industries such as electric vehicles and battery storage, where Chinese companies have become globally dominant players.

How Fast Are China’s Semiconductor Exports Growing?

The report highlighted a sharp rise in semiconductor exports, underlining the sector's growing international presence.

"Exports of electronic integrated circuits rose by 99.6% YoY to US$31.1bn in April and were up 83.7% YoY to US$103.5bn in the first four months of 2026," it said.

These figures indicate that China's semiconductor industry is scaling rapidly, both in production capacity and export reach.

How Have US Restrictions Influenced China’s Chip Industry?

US export controls on advanced semiconductors have become a major catalyst for China's drive toward technological self-reliance.

Jefferies noted that restrictions on access to cutting-edge chips have created incentives for Chinese companies to develop domestic alternatives and strengthen local supply chains.

The report said, "The hottest area of the China stock market of late has been the China AI hardware supply chain where the opportunity to grow has been created by the vacuum left by the US restriction on sales of advanced semiconductors to China."

As a result, China's AI hardware ecosystem has expanded rapidly, supported by both government policy and growing domestic demand.

What Could Happen Next?

Jefferies believes there is still substantial room for growth.

According to the brokerage, China's AI-related capital expenditure remains significantly lower than that of the United States. This suggests that future investment in data centres, AI infrastructure and semiconductor manufacturing could continue to drive expansion for Chinese memory chipmakers.

If current trends persist, YMTC and CXMT could become increasingly influential players in the global memory chip market, intensifying competition in both NAND flash and DRAM technologies while strengthening China's position in the broader AI supply chain.
