AMD shares hit an intraday high near $558 on June 15, pushing the chipmaker’s market capitalization above $900 billion for the first time. The catalyst is a familiar one: AI.
The milestone caps a stretch of aggressive momentum that saw AMD’s valuation approach $850 billion earlier in June. In roughly two weeks, the company tacked on another $50 billion in market cap.
The Samsung deal fueling the fire
On March 18, AMD and Samsung Electronics signed a Memorandum of Understanding at Samsung’s Pyeongtaek facility. The agreement designates Samsung as the primary supplier of high-bandwidth memory, specifically HBM4, for AMD’s upcoming Instinct MI455X GPUs.
Samsung’s HBM4 targets performance metrics of up to 13 Gbps and 3.3 TB/s bandwidth. The deal also covers optimized DDR5 solutions for AMD’s sixth-generation EPYC “Venice” CPUs and the company’s Helios rack-scale platform.
