Introduction

  • TL;DR: OpenAI announced a significant seven-year, $38 billion cloud computing agreement with Amazon Web Services (AWS) on November 3, 2025. This landmark deal provides OpenAI with access to massive computing resources, including hundreds of thousands of NVIDIA GPUs, for training and running its large-scale AI models. Crucially, the announcement follows a recent renegotiation of its partnership with Microsoft, which eliminated Microsoft’s Right of First Refusal on cloud contracts, effectively enabling OpenAI’s pivot to a multi-cloud strategy. This move is closely connected to OpenAI’s recent shift to a Public Benefit Corporation structure and its aggressive, estimated $1.4 trillion commitment to global AI infrastructure spending.

1. The End of Exclusivity: Post-Microsoft Restructuring

Since 2019, Microsoft Azure has been the exclusive primary cloud provider for OpenAI, backed by a significant investment and compute commitment. However, a definitive agreement was signed on October 28, 2025, to restructure the partnership. A key change was the removal of Microsoft’s Right of First Refusal (ROFR) for providing compute services to OpenAI. This contractual revision immediately allowed OpenAI to pursue large-scale partnerships with other cloud providers. The AWS deal, announced just days after the restructuring, confirms a deliberate strategy by OpenAI to diversify its infrastructure providers.

Why it matters: The removal of Microsoft’s exclusivity right is a pivotal moment, granting OpenAI the operational freedom to strategically select cloud partners based on availability, performance, and cost. It fundamentally changes the AI infrastructure landscape, introducing a major competitor to Microsoft’s previous dominance in supporting OpenAI’s frontier model development.

2. AWS Partnership Details: Securing the Compute Backbone

The $38 billion agreement with AWS is a multi-year, seven-year commitment designed to secure the “massive, reliable compute” required for frontier AI scaling, as stated by OpenAI CEO Sam Altman.

  • Compute Resources: The deal provides OpenAI with immediate access to AWS EC2 UltraServers, which are packed with hundreds of thousands of state-of-the-art NVIDIA GPUs (including the GB200 and GB300 chips). The capacity is scalable to tens of millions of CPUs for agentic AI workloads.
  • Deployment Timeline: OpenAI began utilizing the AWS infrastructure immediately on November 3, 2025. The initial target capacity is slated for full deployment before the end of 2026, with provisions for further expansion beyond 2027.
  • Strategic Use: The infrastructure will serve as the backbone for running services like ChatGPT and training OpenAI’s future models.

Why it matters: This enormous commitment underscores the insatiable demand for high-end computing power, particularly NVIDIA GPUs, necessary for developing next-generation AI. For AWS, securing such a massive workload from the industry’s most prominent AI entity represents a major strategic win and validation of its infrastructure capabilities in the face of intense competition.

3. Multi-Cloud Strategy and Infrastructure Investment

The AWS agreement is a cornerstone of OpenAI’s definitive multi-cloud posture. By integrating AWS, alongside existing substantial agreements with Microsoft Azure (an incremental $250 billion commitment) and Oracle Cloud (estimated $300 billion), OpenAI aims to mitigate vendor lock-in risks, optimize for specialized chips, and enhance platform resilience across different geographic regions.

This infrastructure push is part of CEO Sam Altman’s ambitious, estimated $1.4 trillion total commitment to AI infrastructure. The company’s recent regulatory-approved shift from a non-profit to a for-profit Public Benefit Corporation is seen as the structural change necessary to enable this massive capital expenditure and continue pursuing its mission while raising funds more freely.

Oracle Cloud$300B (Estimated)Separate Data Center and Compute Capacity (Previously Announced)

Why it matters: The multi-cloud diversification is a calculated risk management strategy against dependency on any single provider. The scale of the $1.4 trillion commitment indicates a long-term, high-stakes bet on the continued explosion of demand for AI, supported by the recent corporate restructuring that enables this aggressive capital strategy.

Conclusion

OpenAI’s $38 billion deal with AWS is a decisive declaration of the end of its Microsoft exclusivity and the beginning of a true multi-cloud era for frontier AI infrastructure. By securing massive, diversified compute capacity—including critical access to NVIDIA GPUs—OpenAI is positioned to accelerate its AI development pipeline. The move, enabled by a strategic corporate restructuring, solidifies the company’s aggressive investment posture in the global AI race.

Summary

  • OpenAI signed a 7-year, $38B cloud deal with AWS on 2025-11-03, marking a definitive end to Microsoft Azure exclusivity.
  • The agreement provides immediate access to hundreds of thousands of state-of-the-art NVIDIA GPUs via AWS EC2 UltraServers for training and running AI models.
  • The deal is a core component of OpenAI’s new multi-cloud strategy, alongside commitments to Azure and Oracle Cloud.
  • It aligns with OpenAI’s recent shift to a for-profit Public Benefit Corporation structure, which supports its estimated $1.4 trillion infrastructure investment goal.
  • The partnership intensifies the global competition for AI compute resources between major cloud providers.
