Amazon to Invest Up to $25 Billion More in Anthropic, Deepening AI Chip and Infrastructure Ties

OpenAI’s push to expand model training, inference and enterprise products requires vast amounts of capital and computing capacity. Amazon’s investment deepens the companies’ financial and commercial ties while giving its Amazon Web Services unit a strategic role in OpenAI’s infrastructure ecosystem. Under the agreement, AWS will serve as the exclusive third-party cloud provider for the OpenAI Frontier program, strengthening Amazon’s position in the market for enterprise artificial-intelligence workloads.

As of Aug. 2, 2026, Amazon has completed its $50 billion investment in OpenAI, fulfilling the funding commitment ahead of schedule and securing an approximately 5% stake. The transaction extends the relationship beyond cloud services into equity ownership and ranks among the largest strategic investments in the AI sector. The accompanying arrangement makes AWS the sole outside cloud provider for OpenAI Frontier, aligning Amazon’s capital commitment with future demand for computing and enterprise deployment services.

Seattle-based Amazon is stepping up investment in artificial intelligence infrastructure, an increasingly capital-intensive race that requires spending on data centers, computing chips and networking capacity. The outlay is important to Amazon’s ability to support generative AI workloads and compete in cloud services, as the world’s largest technology companies commit growing sums to secure computing capacity and meet demand for AI products.

Amazon has raised its planned AI infrastructure spending for 2026 to $220 billion, up from the $200 billion estimate it issued in April. The $20 billion increase represents a 10% rise from its earlier forecast and signals a further acceleration in investment during the year. The revised plan underscores the scale of capital required as Amazon expands the infrastructure needed to handle rising AI computing demand.

AMD is deepening its ties with Anthropic as developers of large AI models seek to diversify access to advanced chips and computing capacity. The partnership gives AMD a major customer for its Instinct accelerators and strengthens its push into hyperscale AI infrastructure, a market dominated by Nvidia. For Anthropic, the agreement provides another source of hardware for training and running increasingly demanding AI systems.

AMD plans to invest as much as $5 billion in Anthropic under the infrastructure agreement. Anthropic will deploy up to 2 gigawatts of systems powered by AMD Instinct MI450 AI GPUs, with the first installation expected to begin in the first half of 2027. The scale of the commitment underscores the capital and power requirements behind frontier AI development and AMD’s effort to gain ground in the accelerator market.
