According to Woofun AI, leaked financial audit documents disclose that OpenAI generated $13.07 billion in revenue for 2025, yet incurred a net loss of $38.53 billion. The substantial deficit stems primarily from a $41.55 billion loss due to fair value changes in convertible equity and warrants, following the company's structural transition to a for-profit entity. Operating expenses totaled $34 billion, resulting in an operating loss of $20.92 billion.

This performance marks a dramatic year-on-year deterioration compared to 2024, when revenue stood at $3.7 billion and the net loss was $5.09 billion. In 2025, core expenditures escalated significantly, with research and development costs surging to $19.18 billion, revenue costs reaching $7.5 billion, and sales and marketing expenses totaling $5.73 billion. By year-end, OpenAI held assets slightly exceeding $50 billion, with nearly half comprised of cash reserves.

The documents further detail financial interactions with key strategic partners. SoftBank contributed $867 million to OpenAI, while Microsoft provided $303 million. Conversely, OpenAI paid Microsoft service fees amounting to $17.2 billion during the calendar year. Of this sum, $10.59 billion was classified as R&D expenses, widely attributed to model training costs, and $6.047 billion was allocated to revenue costs. As of the end of 2025, OpenAI retained approximately $3.64 billion in liabilities owed to Microsoft.
