Chinese Chip Stocks Jump as Apple Reportedly Tests CXMT Memory Chips for China Devices

Chinese semiconductor stocks rallied on Wednesday after a report suggested Apple (NASDAQ: AAPL) is testing memory chips from domestic manufacturer ChangXin Memory Technologies (CXMT) for devices sold in China, fueling investor optimism over the country’s semiconductor industry despite ongoing U.S. technology restrictions.

Among the biggest gainers, Hua Hong Semiconductor Ltd (SS:688347) surged more than 14% during intraday trading, while Brite Semiconductor Shanghai Co. (SS:688691), also known as Canxin, jumped the daily limit of 20%. Skyverse Technology (SS:688361) climbed 15%, Kingsemi Co. Ltd. (SS:688037) advanced 10%, and Shenzhen-listed Wuhan Jingce Electronic Technology (SZ:300567) gained 13%.

The rally followed a Financial Times report stating that Apple is evaluating DRAM memory chips from state-backed CXMT for products sold in the Chinese market. The report also said Apple is encouraging U.S. policymakers to allow broader use of CXMT’s memory products, although the company has not yet committed to using the chips in commercial devices.

The news boosted confidence across China’s semiconductor supply chain, with investors viewing Apple’s reported testing as a potential endorsement of the country’s rapidly advancing memory-chip capabilities.

CXMT has grown into the world’s fourth-largest producer of DRAM memory chips, supported by significant domestic investment and expanding manufacturing capacity. Industry analysts expect the company’s share of global DRAM production to continue increasing over the next several years as additional fabrication facilities come online.

The reported Apple evaluation comes as Chinese semiconductor companies continue to expand their technological capabilities amid tightening U.S. export controls on advanced chip technologies. Any future commercial partnership between Apple and CXMT could strengthen China’s domestic semiconductor ecosystem while reducing reliance on foreign memory suppliers for products sold in the country.

Although Apple has not confirmed plans to adopt CXMT chips in commercial devices, the report was enough to trigger a broad rally across Chinese memory-chip and semiconductor equipment stocks, reflecting growing investor confidence in China’s chip industry and its long-term growth prospects.
