OpenAI Revenue Jumps to $10 Billion in Third Quarter Amid Growing Losses

Per one person familiar, OpenAI told investors on a Tuesday call that Q3 revenue rose nearly 50% quarter on quarter to $10B, 2.6x the year-earlier quarter. Growth was driven by GPT 5.6, Astra and image models in the API, and by enterprise. Greg Brockman says enterprise doubled in Q3 and is now the majority of revenue. Operating losses widened from $10.1B to $10.9B, while the adjusted operating margin improved from -150% to -109%. Advertising hit a $1B annualised pace in August. Paying users were nearly 100M (22M added in Q3), against 1.2B weekly actives. OpenAI is raising at a $1.25T valuation. For comparison, Anthropic reported nearly $17B of Q3 revenue with a $567M operating deficit. The figures come from a single source, and OpenAI gave no public comment.
