Amazon shares rise after OpenAI inks $38B AWS partnership

Amazon rallied on November 3, 2025 as OpenAI unveiled a multi‑year tie‑up with Amazon Web Services. The $38 billion cloud partnership gives the ChatGPT maker immediate access to fresh computing power and signals a new phase in the AI infrastructure race.

What changed today

OpenAI and AWS announced a multi‑year agreement on November 3, 2025 that will see the AI company run and scale core workloads on Amazon’s cloud. OpenAI gains access to advanced infrastructure, including hundreds of thousands of Nvidia GPUs, with capacity targeted to be fully online by the end of 2026 and room to expand in 2027 and beyond. Amazon shares climbed in early U.S. trading—about 5% at one point—touching an all‑time high, as investors cheered the deal’s implications for AWS competitiveness. Reuters and AP reported the move.

Context

The partnership follows OpenAI’s recent restructuring and updated terms with Microsoft that allow it to diversify cloud suppliers. AWS said the deployment will use EC2 UltraServers to cluster Nvidia’s latest GB‑series accelerators for both model training and ChatGPT inference. OpenAI framed the arrangement as a way to meet surging compute needs while keeping options open across providers, citing immediate use of AWS capacity and a clear ramp‑up plan through 2026. OpenAI characterized the pact as a strategic, multi‑year commitment.

Why it matters

For Amazon, the agreement is a high‑profile validation of AWS’s ability to win flagship AI workloads against cloud rivals. For OpenAI, the deal helps secure the resources required to train and serve increasingly capable models at global scale. Analysts say the arrangement could broaden OpenAI’s supplier base while reinforcing AWS’s role in the AI stack. The companies indicated a seven‑year agreement valued at $38 billion with all capacity targeted by end of 2026, underscoring the pace and magnitude of expected demand.

What’s next

OpenAI said it will begin using AWS immediately, with deployments accelerating through 2026. AWS executives described the compute as dedicated capacity built out specifically for OpenAI, while both sides highlighted ongoing collaboration around managed services and tooling.
