Following a year of intense dealmaking and speculations about an imminent IPO, OpenAI is facing increased financial scrutiny. Leaked documents obtained by tech blogger Ed Zitron shed light on OpenAI’s financial status, particularly its revenue and compute costs in recent years.
Amidst swirling rumors, the financial spotlight is now shining brightly on OpenAI, with leaked documents revealing intriguing insights into the company’s financial health. According to tech blogger Ed Zitron, Microsoft received substantial revenue share payments from OpenAI in 2024, amounting to $493.8 million. This figure surged to $865.8 million in the first three quarters of 2025, as per the documents Zitron examined.
Reports indicate that OpenAI shares 20% of its revenue with Microsoft, stemming from a significant investment by the software giant into the AI startup. However, the financial dynamics between the two entities become more intricate, as Microsoft also reciprocates by sharing revenue from Bing and Azure OpenAI Service with OpenAI. This symbiotic relationship underscores the interdependence between the tech giants in the AI landscape.
Interestingly, leaked payments refer to Microsoft’s net revenue share, excluding any payments made to OpenAI for Bing and Azure OpenAI royalties. This nuanced financial arrangement adds a layer of complexity to understanding the true extent of revenue sharing between the two companies.
Despite the financial intricacies, the leaked documents offer a rare glimpse into OpenAI’s financial performance, showcasing not only its revenue but also its expenditure relative to earnings. The numbers paint a compelling picture of a company at the forefront of private market dominance.
