AI stocks rally today as Nvidia seeks more H200 chips; AMD and Micron lead early gains

Nvidia shares rose 2.9% to $191.93 on Friday after Reuters reported the AI chipmaker had approached Taiwan Semiconductor Manufacturing Co about ramping up production of its H200 graphics processing units, chips used to train and run AI models.

TSMC stock forecast 2026: New U.S. China licence and Nvidia H200 push put targets in focus

Taiwan Semiconductor Manufacturing Co said the U.S. Department of Commerce granted its Nanjing unit an annual export licence that allows U.S. export-controlled items to be supplied without the need for individual vendor licences. The approval replaces a waiver known as validated end-user status — which let designated plants receive some controlled items with fewer approvals — that expired on Dec. 31, and Samsung Electronics and SK Hynix have received similar licences. TSMC said the Nanjing fab makes 16-nanometre and other mature-node chips and generated about 2.4% of the company’s 2024 revenue. Reuters
