OpenAI’s First Half Results: $4.3 Billion in Sales, $2.5 Billion Cash Burn

OpenAI generated around $4.3 billion in revenue in the first half of 2025, about 16% more than it generated all of last year, according to financial disclosures to shareholders.

The company said it burned $2.5 billion, in large part due to its research and development costs for developing artificial intelligence and for running ChatGPT. Some of its largest expenses were non-cash, including stock payments to employees.
