China memory chipmaker CXMT debuts on the Shanghai market after what multiple outlets describe as a major chip initial public offering in years. Across reports, CXMT’s shares open and then trade at levels several times higher than the IPO price, with gains reported around the mid-to-high 400% range by various outlets. Channel NewsAsia, India Today, and Yahoo Finance cite increases of roughly 466% to 470% in the trading debut. Seeking Alpha and MarketWatch also report a similar first-day surge, describing the stock as rising about fivefold (or approximately 500% in one account). MarketWatch reports that CXMT closes its first trading day with a market capitalization of about US$85 billion, while Seeking Alpha says the rally lifts the valuation above US$539 billion. The different valuation figures reflect variation in reported reference points and methodology, but all sources agree on the central point: CXMT’s shares experience an exceptional spike on their first day of trading in Shanghai following a record chip IPO.
