Enterprise sales push OpenAI's quarterly revenue to $10 billion, though it still trails Anthropic

OpenAI's Q3 revenue rose about 50% quarter over quarter to $10 billion, driven by new models and enterprise customers, while adjusted operating losses grew slightly to $10.9 billion from $10.1 billion. Anthropic, which plans its IPO next week, grew Q3 revenue 47% to $17 billion with an operating loss including stock compensation of just $567 million. OpenAI says its enterprise business doubled in Q3 and now accounts for the bulk of revenue, and ChatGPT has 1.2 billion weekly active users with 100 million paying subscribers.
