In a document resembling an IPO prospectus, OpenAI has identified its deep relationship with Microsoft as a potential business risk. The AI firm noted that Microsoft provides a substantial portion of its financing and compute resources, a critical detail shared with prospective investors.
OpenAI recently announced a significant funding round totaling $110 billion from partners like Amazon, Nvidia, and SoftBank. The company is actively pursuing an additional $10 billion in commitments from a broader investor base, with this part of the round expected to close by the end of March 2026.
These disclosures offer a glimpse into OpenAI's upcoming public filing, as the company prepares for a potential IPO later this year. Beyond its reliance on Microsoft, OpenAI also flagged risks associated with its substantial capital expenditures, compute resource needs, ongoing litigation with xAI, and its unique public benefit corporation structure.
Founded as a nonprofit in 2015, OpenAI has experienced explosive commercial growth since launching ChatGPT in late 2022. The platform now serves 900 million weekly active users, and the company reported $13.1 billion in revenue for 2025, achieving a $730 billion valuation last month.
