OpenAI signed a seven‑year, $38 billion agreement to run and scale its AI workloads on AWS. The deal gives the ChatGPT maker immediate access to AWS infrastructure, including clusters built around hundreds of thousands of Nvidia GPUs, with planned capacity coming online by the end of 2026 and room to expand into 2027 and beyond.

The agreement bolsters AWS’s position in the AI infrastructure race and addresses OpenAI’s need for far more compute to train and serve advanced models. Investor enthusiasm pushed Amazon’s stock up roughly 5% on the day, reflecting expectations for stronger AWS demand tied to the new workloads.

The announcement comes days after OpenAI restructured its organization and revised terms with longtime backer Microsoft, ending Azure’s exclusivity and allowing OpenAI to diversify cloud providers. AP reported that regulators in California and Delaware approved steps enabling OpenAI’s new business structure.

Amazon highlighted that OpenAI will tap AWS clusters featuring Nvidia’s current and next‑gen accelerators (GB200 and GB300) via Amazon EC2 UltraServers, with scale designed for both training and inference. The companies said all targeted capacity is expected online by late 2026. ([apnews.com](https://apnews.com/article/071e752773dee5713c8b1a10039d08aa))
The surge also follows Amazon’s October 30, 2025 earnings, where management pointed to re‑accelerating AWS growth and expanding AI capacity—backdrop that likely amplified Monday’s rally.

OpenAI is pursuing massive long‑term compute build‑outs—commitments that news outlets have tallied at more than $1 trillion across data centers and chips—while Amazon continues investing to meet rising AI demand. The OpenAI‑AWS partnership is expected to scale progressively through 2026, with further expansion potential thereafter.
