Shocking Leaks: OpenAI Paid Microsoft $1.36 Billion in Revenue Sharing Amid Soaring AI Compute Costs
Explosive leaked documents have uncovered the staggering financial relationship between OpenAI and Microsoft, revealing payments totaling $1.36 billion in revenue sharing while exposing the brutal reality of AI compute costs that may be outpacing revenue. These revelations come at a critical moment for cryptocurrency and AI investors seeking to understand the true economics behind the artificial intelligence boom.
According to documents obtained by tech blogger Ed Zitron, Microsoft received $493.8 million in revenue share payments from OpenAI in 2024 alone. The situation intensified dramatically in 2025, with Microsoft collecting $865.8 million in just the first three quarters. This financial arrangement stems from Microsoft’s massive $13 billion investment in OpenAI, creating one of the most significant partnerships in tech history.
The leaked information reveals a complex revenue sharing arrangement where OpenAI pays Microsoft approximately 20% of its revenue. However, the relationship works both ways – Microsoft also returns about 20% of revenues from Bing and Azure OpenAI Service back to the AI startup. This creates a sophisticated financial ecosystem where both companies benefit from each other’s success.
The most alarming revelation concerns OpenAI’s compute expenditure. Analysis suggests the company spent approximately $3.8 billion on inference costs in 2024, skyrocketing to $8.65 billion in the first nine months of 2025. Inference represents the computational power required to run trained AI models and generate responses – essentially the ongoing operational cost of providing AI services.
| Year | Inference Costs | Revenue Share to Microsoft |
|---|---|---|
| 2024 | $3.8 billion | $493.8 million |
| 2025 (First 9 months) | $8.65 billion | $865.8 million |
These leaked documents provide unprecedented insight into the financial health of the AI industry’s leading company. Based on the 20% revenue share percentage, we can infer OpenAI generated at least $2.5 billion in 2024 revenue and $4.33 billion in the first three quarters of 2025. However, CEO Sam Altman has suggested the company’s actual performance is even stronger, claiming OpenAI could reach $100 billion in revenue by 2027.
The financial data suggests OpenAI might be spending more on inference costs than it earns in revenue, raising serious questions about the sustainability of current AI business models. This revelation comes as the AI industry faces increasing scrutiny about whether current valuations and investment levels are justified by actual financial performance.
The partnership involves Microsoft providing substantial computational resources through Azure cloud services in exchange for revenue sharing and exclusive access to OpenAI’s technology for certain applications.
Microsoft has invested over $13 billion in OpenAI through multiple funding rounds, making it the startup’s primary financial backer and strategic partner.
Inference costs refer to the computational expenses required to run trained AI models and generate responses for users, as opposed to training costs which involve initially developing the models.
Tech blogger Ed Zitron obtained and reported on the leaked documents, though the original source remains unidentified.
These revelations could impact investor confidence and valuation expectations across the AI sector, particularly for companies with similar compute-intensive business models.
The leaked financial documents between OpenAI and Microsoft reveal an industry grappling with the enormous costs of artificial intelligence while pursuing unprecedented growth. As compute expenses potentially outpace revenue, the entire AI sector faces crucial questions about sustainability and profitability that will shape investment decisions for years to come.
