Chinese chip champion CXMT soars more than 500% in market debut

CXMT shares soared more than 500 per cent in their trading debut in Shanghai on Monday as investors flocked to the chipmaker amid booming demand for AI memory chips.

The stock opened at Rmb49.50 ($7.30) a share, compared with an IPO price of Rmb8.66 and rose further in afternoon trading to Rmb54.65.

The surge sent CXMT’s market value to Rmb3.65tn ($539bn), making it the most valuable public Chinese company ahead of Hong Kong-listed Tencent, worth $514bn.

CXMT’s debut comes two weeks after SK Hynix, the South Korean memory-chip maker, raised more than $26bn in a US listing.

The Chinese chipmaker is raising money to expand production as well as research and development of DRam chips, which store short-term memory in computers.

CXMT turned profitable this year, raking in Rmb33bn ($4.9bn) in the first quarter alone, in a striking reversal from the Rmb37bn in losses it built up over the past decade. The company has benefited from a…
