SINGAPORE/SHANGHAI, July 27 (Reuters) – Shares of CXMT Corp are set to start trading in Shanghai on Monday after Asia’s biggest IPO this year, putting the Chinese chipmaker’s $85.5 billion market value and likely heavy turnover ​in focus after a sharp pullback in tech shares.

The debut will give investors ‌a gauge of how much they are willing to pay for a marquee Chinese chip firm, as local markets navigate volatility following an AI-led selloff, and money rotates between high-growth technology names and safer sectors.

CXMT, formally ChangXin Memory Technologies, raised 57.92 billion yuan ($8.6 billion) by selling shares at 8.66 yuan each, its ‌listing ​documents showed. Proceeds could rise to 66.61 billion yuan if ⁠an over-allotment option is fully used.

At ⁠the IPO price, CXMT is valued at about 579 billion yuan ($85.5 billion) before the possible exercise of the over-allotment option, making it one of China’s largest listed semiconductor companies.

Only 6.73% of CXMT’s enlarged share capital will be freely tradable at listing, as ​most shares are locked up. The small initial float could magnify price swings and attract strong turnover.

HSBC Qianhai Securities said in a note last week that the offering could ⁠drain liquidity from the wider Chinese market before ⁠and on its debut, though past technology listings suggested a rebound could ​follow the next trading day.

BIGGEST EVER

CXMT makes DRAM chips, a type of memory chip used ​in phones, computers and servers. It is the world’s fourth-largest DRAM maker after ‌Samsung Electronics, SK Hynix and Micron Technology.

The company’s IPO is the biggest mainland Chinese semiconductor offering on record, surpassing SMIC’s $7.5 billion Shanghai share sale in 2020.

Morningstar analyst Jing Jie Yu wrote in a report on Friday that CXMT was well-placed to benefit from rising domestic AI ⁠demand, but its technology gap with global leaders could limit its share of the market for memory chips used in AI systems.

Its debut comes after Shanghai’s tech-focused STAR 50 Index edged ⁠down 0.1% on Friday, while ‌the broader Chinese and Hong Kong markets fell as higher oil ⁠prices amid renewed Iran war concerns hurt risk appetite.

CXMT said in ​its ‌prospectus that AI demand helped drive the latest DRAM upswing, but ​said the ⁠market could weaken if AI investment slowed or rivals added too much supply.

The company expects first-half revenue to rise more than sevenfold to 110 billion yuan to 120 billion yuan. It expects net profit of 66 billion yuan to 75 billion yuan, reversing a year-earlier loss.
