Reuters exclusively reported that Chinese chip designers including Tencent Holdings (0700.HK) are aggressively pitching their AI chips as alternatives to Nvidia’s (NVDA.O), hoping U.S. export restrictions will prompt clients to switch, said four people familiar with such discussions. California-based Nvidia commands as much as 90% of China’s $7 billion market for chips used to process enormous amounts of data to develop artificial intelligence (AI) software.
