AMD Expands AI Compute Tie-Up With Anthropic, Pointing to Larger HBM4 Demand

AMD and Anthropic announced a strategic partnership centered on future Instinct MI450 deployments and a potential equity investment of up to $5 billion by AMD. The first gigawatt of capacity is scheduled for the first half of 2027 in AMD Helios rack-scale systems. The announcement also confirms that Anthropic is already running workloads on current-generation AMD MI355X GPUs. AMD said the Helios configuration for Anthropic combines Instinct MI455X accelerators, EPYC Venice CPUs, Pensando networking and ROCm software. The company describes each rack as carrying 72 accelerators and 31 TB of HBM4, which makes the agreement notable for high-bandwidth memory demand even though it does not directly change DRAM or NAND contract pricing today. For RamTrend, the main takeaway is that another large AI infrastructure commitment supports the medium-term outlook for premium memory content in accelerator platforms. The near-term pricing effect is limited because deployment starts later, but the deal reinforces expectations of sustained demand for HBM-linked supply through 2027.
