ChangXin Memory Technologies priced its Shanghai IPO at 8.66 yuan per share on July 16. The company will raise up to $9.83 billion and enter the market on a $85 billion valuation. The listing is the largest by a Chinese semiconductor company on a mainland exchange.

More than 9.4 million investors applied for shares. Retail demand ran 212 times oversubscribed. That is a 212-to-1 ratio. Shanghai has not seen demand like this in years.
The Story Behind ChangXin
ChangXin makes DRAM chips—the memory that powers phones, laptops, and servers. The company was founded in 2016 by Zhu Yiming, a billionaire who previously founded GigaDevice Semiconductor. ChangXin has no parent company. It is independent.
The company is profitable. First-half net profit surged up to 25 times compared to the prior year. The math is identical to Samsung‘s story: AI demand, memory shortage, pricing power.
Founder Zhu pledged not to sell shares for a decade. That is unusual and signals confidence. Most new IPO insiders take chips off the table immediately.
China’s Chip Independence
This IPO is symbolic. China is pouring capital into domestic chip manufacturing. The US export controls are pushing Chinese companies to self-sufficiency. ChangXin is proof it works. The company makes leading-edge DRAM that competes with Samsung and SK Hynix.
The oversubscription shows investors believe in the story. ChangXin will trade on the Shanghai STAR Market under ticker 688825 starting July 27.
What This Means
The US will lose some leverage in chip supply chains. Chinese memory makers are now well-capitalized and competitive. Samsung and SK Hynix should expect tougher competition in the next two years, particularly in the Chinese market.
ChangXin’s IPO is a watershed moment for Chinese semiconductor independence. The capital is now there to scale.
