CXMT Corp is set to start trading in Shanghai on Monday after completing what has been described as Asia's biggest IPO this year. The market debut puts the Chinese memory chipmaker in the spotlight as investors watch pricing, liquidity and early trading activity.

At the IPO price, CXMT is valued at about 579 billion yuan, or roughly $85.5 billion, before any possible exercise of the over-allotment option. That valuation makes it one of China's largest listed semiconductor companies and gives the listing added weight in the domestic chip sector.

The Shanghai debut is significant because of both its size and timing. It highlights investor interest in Chinese semiconductor companies at a time when the market is closely tracking funding, expansion and competitiveness across the country's chip industry.

Heavy turnover is likely to be a major focus once trading begins, given the scale of the offering and the attention surrounding the stock. For the broader market, CXMT's first sessions in Shanghai may be seen as an early test of how strongly investors are prepared to back a major memory chipmaker at this valuation.
