OpenAI's 2025 Losses Surge to $38.5 Billion as Spending Reaches $34 Billion

OpenAI experienced a dramatic financial deterioration in 2025, with losses increasing nearly eightfold compared to 2024, according to audited financial documents independently verified by the Financial Times. The artificial intelligence company reported a net loss attributable to the company of $38.5 billion in 2025, a sharp increase from the $5.09 billion loss recorded in 2024.

The 2025 financial results reflect OpenAI's mounting operational costs amid aggressive investment in research and development. The company generated $13.07 billion in revenue while incurring $34 billion in total costs and expenses. Research and development spending alone reached $19.18 billion, while cost of revenue totaled $7.5 billion, sales and marketing expenses were $5.73 billion, and general and administrative costs amounted to $1.57 billion. Operating losses reached $20.92 billion before accounting for other financial factors.

A significant driver of the 2025 loss was OpenAI's conversion from a non-profit to a for-profit entity during the year, which triggered a $41.55 billion loss related to changes in fair value of convertible interests and warrant liability. After accounting for this structural change, interest income and expenses, and other adjustments including removals totaling $21.82 billion via "net loss attributable to noncontrolling members capital" and "net loss attributable to redeemable noncontrolling interests," the company's final net loss attributable to OpenAI reached $38.5 billion.

Despite the substantial losses, OpenAI maintained a relatively strong balance sheet, holding just over $50 billion in total assets at year-end, with approximately half in cash. The company received significant funding support during 2025, with SoftBank contributing $867 million and Microsoft paying $303 million. OpenAI's relationship with Microsoft involved substantial expenses, totaling $17.2 billion in 2025 for research and development, cost of revenue, and other services, with OpenAI carrying $3.64 billion in liabilities to Microsoft at year-end.

Comparable to 2024, when OpenAI had $3.7 billion in revenue and $12.48 billion in total costs and expenses, the 2025 figures demonstrate significant scaling of both revenue generation and spending. The company's financial trajectory indicates accelerating investments in AI model development and infrastructure, though accompanied by mounting losses characteristic of the capital-intensive nature of artificial intelligence advancement.
