About 70% of Microsoft’s (MS) artificial intelligence (AI) revenue is estimated to come from OpenAI. While MS is expanding its own AI business, it remains significantly reliant on OpenAI for actual revenue.
According to Bloomberg on August 5, MS disclosed that it generated $24.1 billion in revenue related to OpenAI for the fiscal year ending in June 2026. This is the first time MS has specifically reported annual revenue generated from OpenAI.
OpenAI utilizes MS's cloud computing resources for AI model development and service operations, compensating MS for these services. The $24.1 billion includes fees for cloud usage and revenue sharing agreements.
MS did not disclose its total AI revenue for the same period. However, Bloomberg estimates that MS's overall AI revenue for the last fiscal year was approximately $34 billion, based on previously announced growth rates in its AI business.
Based on this calculation, revenue related to OpenAI accounts for about 70% of MS's total AI revenue. It is important to note that this 70% figure is an estimate derived from Bloomberg's analysis of publicly available data, not an official MS announcement.
To reduce its dependence on OpenAI, MS is developing its own AI models and investing in competitors like Anthropic. Investors are particularly interested in how much of MS's AI revenue comes from general corporate clients and its own AI products, rather than OpenAI.
Market analysts emphasize the importance of the composition of revenue related to OpenAI. The more revenue generated from actual services provided, such as cloud and software, rather than revenue sharing with OpenAI, the more stable the business is perceived to be.
Jackson Ader, an analyst at KeyBanc, stated, “If revenue related to OpenAI is generated more from service provision than from investment returns, it would be viewed more positively.”
