Advanced Micro Devices (AMD) committed to invest up to $5 billion in Anthropic, while the companies entered into a strategic partnership covering AMD chips.
AMD will make the investment in the Amazon.com-backed (AMZN) artificial intelligence firm "in the future," the companies said Wednesday.
The strategic partnership covers the deployment of up to 2 gigawatts of AMD Instinct MI450 series graphics processor units in AMD Helios rack-scale solutions, with initial deployment starting in the first half of next year. Anthropic is already using AMD Instinct MI355X GPUs, according to a joint statement.
"We are thrilled to deepen our partnership with Anthropic and deploy AMD Helios at gigawatt scale," AMD Chief Executive Lisa Su said. "This collaboration brings together Anthropic's leadership in frontier AI with the full strength of AMD high-performance computing."
AMD shares were up 1.8% in Wednesday late-afternoon trade, bringing its year-to-date gains to about 159%.
"By partnering with AMD across the stack, we are securing the capacity we need and optimizing it for training and serving Claude," Anthropic Chief Compute Officer Tom Brown said.
The companies are also launching a multiyear engineering collaboration under which teams will use Claude to optimize workloads for AMD Instinct GPUs and accelerate ROCm software development. ROCm is an open-source software stack designed for GPU computation.
AMD will "broadly adopt" Claude across its engineering and product development teams, the companies said.
Earlier this year, Anthropic expanded its partnership with existing backer Amazon, which said at the time it was investing another $5 billion in the Claude maker, with up to an additional $20 billion in the future. The AI company confidentially filed for an initial public offering in the US earlier in 2026.
The Anthropic collaboration marks the latest deal for AMD, which earlier this week announced an expanded strategic partnership spanning its GPUs, central processing units, networking and software on Microsoft's (MSFT) Azure cloud-computing platform.
AMD is scheduled to report its fiscal second-quarter results Aug. 4.
