TLDRs;
- OpenAI signed a $38 billion deal with Amazon Web Services to access Nvidia GPUs and scale AI workloads.
- The agreement breaks OpenAI’s exclusive cloud ties with Microsoft, diversifying its infrastructure base.
- Amazon stock rose nearly 5% after the deal, boosting investor confidence in its AI leadership.
- The partnership underscores growing competition among hyperscalers to power next-gen AI systems.
OpenAI has entered a monumental $38 billion partnership with Amazon Web Services (AWS), marking its first-ever collaboration with the global cloud leader.
The deal, unveiled Monday, will allow OpenAI to run massive AI workloads using hundreds of thousands of Nvidia graphics processing units (GPUs) hosted on AWS infrastructure in the United States.
The agreement represents one of OpenAI’s most significant moves away from Microsoft, which had served as its exclusive cloud provider since 2019. Under the new multi-year deal, AWS will provide both existing and newly built compute capacity tailored to OpenAI’s training and inference workloads.
“This is a separate, purpose-built capacity for OpenAI,” said Dave Brown, vice president of compute and machine learning services at AWS. “Some of that capacity is already available, and OpenAI is making use of that immediately.”
Amazon shares surged nearly 5% following the announcement, reflecting investor optimism about AWS’s expanding role in the AI infrastructure market.
A Major Shift from Microsoft
The partnership signals a broader shift in OpenAI’s strategy. Earlier this year, Microsoft’s exclusivity agreement expired, giving OpenAI the freedom to partner with other hyperscalers. While the company will still rely heavily on Microsoft Azure, with an additional $250 billion in cloud spending recently reaffirmed, it now gains flexibility to diversify and strengthen its global compute backbone.
OpenAI CEO Sam Altman hailed the AWS collaboration as crucial to scaling “frontier AI” systems.
“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.” He stated.
This diversification comes amid an aggressive buildout spree by OpenAI, which has announced over $1.4 trillion worth of compute and infrastructure deals involving Nvidia, Google, Oracle, and Broadcom. Industry analysts say such moves position OpenAI as less dependent on any single provider and better equipped to handle rising demand for large-scale model training.
AWS Strengthens Its AI Credentials
For Amazon, the deal is a decisive win. The world’s leading cloud platform will not only provide capacity for OpenAI but also bolster its credibility as the backbone for advanced AI systems. Amazon CEO Andy Jassy called the agreement a validation of Amazon’s scale and readiness.
The partnership arrives as AWS faces fierce competition from Microsoft and Google Cloud, both of which reported faster year-over-year growth in their cloud divisions. Still, AWS remains the largest player in the global cloud market by revenue and capacity.
Interestingly, Amazon has also been investing heavily in Anthropic, an OpenAI rival, committing billions toward dedicated infrastructure and an $11 billion data-center campus in Indiana. The OpenAI deal demonstrates Amazon’s ability to maintain strategic neutrality while supporting multiple leading AI startups.
