AMD face growing pressure in China as local companies shift more AI chip spending toward domestic suppliers, according to a Bloomberg survey.
The survey of 60 Chinese executives found they plan to allocate 46% of AI chip budgets to domestic options over the next 12 months, up from 30% today. About 80% also said AI infrastructure projects are running over budget, adding pressure to find cheaper and more available local alternatives.
Huawei, Hygon and Cambricon are expected to benefit, while Tencent (TCEHY), Alibaba 
BABA, China Telecom and China Mobile remain major builders of AI data centers. Chinese firms still use Nvidia’s H20 and AMD’s MI308 accelerators, but their share is expected to fall as Beijing pushes domestic options and supply becomes tighter.
the survey highlights a rising China risk for U.S. chipmakers even as global AI demand remains strong. Nvidia fell 1.6% and AMD slipped 3.7% in premarket trading Tuesday.
