OpenAI Taps Google Cloud to Boost AI Infrastructure, Diversifies Beyond Microsoft

OpenAI has officially added Google Cloud to its list of infrastructure providers, joining a growing lineup that includes Microsoft Azure, Oracle, and CoreWeave. The move, confirmed on OpenAI’s website and first reported by Reuters, highlights the company’s strategy to meet soaring computing demands as it scales advanced AI models like ChatGPT.

The agreement with Google Cloud, finalized in May 2025 after months of negotiations, represents a significant shift in the competitive cloud landscape. Until earlier this year, Microsoft had been OpenAI’s exclusive cloud provider. However, OpenAI has recently expanded its partnerships, underscoring the need for diversified compute resources amid skyrocketing AI workloads.

In addition to Google, OpenAI has secured multi-billion-dollar deals with CoreWeave and entered a major infrastructure initiative with Oracle and SoftBank, known as the $500 billion Stargate project. These moves are aimed at boosting AI training capacity and reducing overreliance on Microsoft, a key backer of OpenAI since its early stages.

Sources indicate that earlier efforts to sign a deal with Google were delayed due to OpenAI’s previous exclusivity agreement with Microsoft. With that limitation now lifted, OpenAI is free to collaborate with other tech giants to ensure it can scale its AI systems efficiently and cost-effectively.

The addition of Google Cloud reflects growing industry pressure on AI firms to secure massive compute power across multiple providers. As OpenAI pushes the boundaries of generative AI, diversifying its infrastructure partners not only enhances performance and reliability but also hedges against potential bottlenecks or pricing constraints from a single vendor.

This strategic alignment underscores a broader trend in the AI arms race, where cloud providers like Google, Microsoft, Oracle, and CoreWeave compete to power the next generation of intelligent systems.
