OpenAI identifies its reliance on Microsoft for funding and computing as a significant business risk in pre-IPO documents. The company’s asset-light strategy keeps server and data center costs off the balance sheet. This model creates operational vulnerability if the Microsoft relationship changes.

OpenAI and Microsoft restructured their partnership to grant OpenAI more flexibility with other cloud providers. The company reports significant revenue growth alongside staggering financial losses. One-time non-cash charges from corporate restructuring drove a portion of these losses. Investors must weigh this growth against massive expenses and the strategic Microsoft dependency.
