OpenAI has identified its heavy operational and infrastructure dependence on Microsoft as a major risk factor in preparatory documents for a potential initial public offering. The company noted that Microsoft provides a significant portion of the compute resources necessary for its AI workloads.
Context
OpenAI has reportedly identified its deep infrastructure reliance on Microsoft as a primary risk factor in financial documents shared with investors ahead of a potential IPO. The disclosure warns that if Microsoft modifies or terminates its commercial partnership, or if OpenAI fails to diversify its partners, its financial condition could be adversely affected. OpenAI generated $13.1 billion in revenue in 2025 and was recently valued at $730 billion, with Microsoft currently holding a 27% stake valued at approximately $135 billion.
This risk assessment follows a major shift in the AI supply chain as OpenAI moves toward a multi-cloud strategy. In late 2025, OpenAI ended its exclusive compute relationship with Microsoft by signing a $38 billion alliance with Amazon Web Services (AWS) and a $300 billion deal with Oracle. Despite this diversification, an OpenAI spokesperson stated that the disclosure is a "standard legal risk factor" and that "Microsoft is and will remain a critical long-term partner."
