On the final trading day of the first half of 2026, China's A-share market reached a historic milestone as shares of artificial intelligence chip leader Cambricon Technologies (688256.SS) surged more than 8% as of the morning close on June 30, propelling its total market capitalization past the 1 trillion yuan mark. It became the first stock listed on the Shanghai Stock Exchange's STAR Market to enter the trillion-yuan club. As of the morning close, Cambricon's year-to-date gain had reached 77.44%. According to data from financial terminal provider Hithink RoyalFlush, Cambricon now ranks ninth across the entire A-share market by free-float market capitalization, with three other AI infrastructure-related names—Foxconn Industrial Internet, Zhongji Innolight, and Hygon Information Technology—also in the top 10. During the morning session on June 30, AI computing-related tech names were broadly in the green while traditional blue chips declined. Behind Cambricon's breakthrough lies an intensifying global AI infrastructure race; on June 29, South Korea's government, Samsung Electronics, and SK Group unveiled "three mega projects," pledging a combined total of 4,755 trillion won in AI-related fields. Last week, Nvidia CEO Jensen Huang stated that AI infrastructure has fully entered the production phase, with the buildout to be measured in decades.
