OpenAI reports that ChatGPT now reaches 1.2 billion people every week. The company states this figure includes active weekly users across its standard interface, ChatGPT Work, and Codex coding assistant. This usage surge comes as OpenAI approaches an annualised revenue rate of $70 billion, a figure that rose roughly 70 percent since the start of the third quarter. Anthropic reportedly passed $65 billion in July and may soon match or exceed those numbers. OpenAI attributes this growth to enterprise sales and an aggressive price war against Claude and Chinese models. The strategy intensified with the launch of GPT-6.1-Sol, while Codex expansion rides the popularity of the GPT-6 model family. DevDay figures also note 2.5 million businesses using OpenAI products. The critical question remains whether revenue can grow fast enough to cover the massive data centre bills required to support such scale.
The scale of adoption highlights the financial pressure on the infrastructure supporting these models. High usage drives costs that must be offset by subscription and enterprise contracts. Without matching revenue growth, current pricing strategies could strain margins significantly.
