OpenAI has signed a $38 billion seven-year agreement with Amazon Web Services (AWS) which will see the generative AI giant run its workloads on AWS infrastructure.

Under the terms of the deal, OpenAI will have access to “hundreds of thousands” of Nvidia GB200s and GB300s via Amazon EC2 UltraServers, with the ability to also expand access to tens of millions of CPUs.

OpenAI will have access to some compute infrastructure immediately, with all expected capacity to be deployed before the end of 2026 – although neither company has disclosed what capacity is being targeted.

The partnership will also allow OpenAI to further expand its deployments into 2027 and beyond, with CNBC reporting that the first phase of the deal will use existing AWS data centers, but future infrastructure build out will be required by Amazon to support the capacity needs of OpenAI.

In Amazon’s Q3 2025 earnings call, CEO Andy Jassy said that AWS's backlog had grown to $200bn by the end of the quarter, and didn’t include "several unannounced new deals in October, which together are more than our total deal volume for all of Q3." He also noted that the company had added 3.8GW of power in the last 12 months.

"To put that in perspective, we're now double the power capacity that AWS was in 2022, and we are on track to double again by 2027," Jassy said.

Commenting on the deal with AWS, OpenAI co-founder and CEO Sam Altman said: “Scaling frontier AI requires massive, reliable compute. Our partnership with AWS strengthens the broad compute ecosystem that will power this next era and bring advanced AI to everyone.”

“As OpenAI continues to push the boundaries of what's possible, AWS's best-in-class infrastructure will serve as a backbone for their AI ambitions. The breadth and immediate availability of optimized compute demonstrates why AWS is uniquely positioned to support OpenAI's vast AI workloads,” said Matt Garman, CEO of AWS.

Microsoft had previously been OpenAI’s exclusive cloud partner; however, following the Stargate announcement in January 2025, the two companies confirmed their partnership was no longer exclusive.

Following this, OpenAI has signed agreements with Google Cloud, CoreWeave, and Oracle, the latter of which is expected to be worth as much as $300 billion over five years.

Last week, OpenAI completed a transition to a for-profit public benefit corporation called OpenAI Group PBC., with the original non-profit – now called the OpenAI Foundation – holding a 26 percent stake in the PBC worth around $130 billion, with Microsoft owning a 27 percent stake worth $135bn.

This is the third major deal announced by OpenAI in the past several weeks, following its agreement with AMD for the supply of hundreds of thousands of GPUs and a partnership with Broadcom for the co-development of custom AI hardware.

The company also signed a letter of intent to deploy at least 10GW of Nvidia hardware in its data centers in September 2025.

OpenAI was valued at $500 billion in early October but has yet to turn a profit. While appearing on the Bg2 Pod with Microsoft CEO Satya Nadella this weekend, Altman was asked how a company with reported revenues of $13bn could commit to $1.4 trillion in spend. In response, the CEO said that the company was “doing... more revenue than that,” adding that it is planning “for revenue to grow steeply.”

He did not clarify how much more than $13bn figure the company has generated.
