OpenAI Announces 400 Million Weekly Active Users For its Products

OpenAI crossed 400 million weekly active users in February, the company’s COO Brad Lightcap told CNBC this week. That number presumably includes all of OpenAI’s AI services, including the popular ChatGPT chatbot and the Sora video generation model

In December, the company announced that ChatGPT had 300 million weekly active users, with 1 billion user messages sent to the chatbot every day. Speaking with CNBC, Lightcap also said that OpenAI now had 2 million paying enterprise customers, a number that doubled since September 2024.

“We get a lot of benefits, and a tailwind from the organic consumer adoption where people already have familiarity with the product,” he said. “There’s really healthy growth, on a different curve.”

On the developer front, Lightcap said that usage doubled in the past six months. These solid growth numbers come after OpenAI announced Project Stargate, which will see the company invest $500 billion in AI infrastructure over the next four years with the support from SoftBank, Oracle, and MGX.

Despite OpenAI and other AI players like Google and Microsoft facing new competition from China-based DeepSeek and its cost-saving designs, Lightcap believes that the “natural progression” of OpenAI’s products will continue. “AI is going to be like cloud services. It’s going to be something that you can’t run a business that ultimately is not really running on these very powerful models underneath the surface,” the exec said.
