ChatGPT Reaches 900 Million Weekly Users as OpenAI Expands AI at Global Scale

OpenAI's ChatGPT has surpassed 900 million weekly active users, marking it as one of the most widely used AI products in everyday work and personal computing. In its February 2026 announcement, the company also disclosed that over 50 million consumer subscribers and more than 9 million paying business users rely on ChatGPT for various tasks.

Furthermore, there are 1.6 million weekly users of OpenAI's coding product, Codex. This surge in usage signals an expanding demand for conversational AI, which is reshaping how people engage with the technology in their daily lives. For businesses, the milestone is not merely a popularity contest but a testament to the changing user behavior.

As familiarity with conversational AI grows, businesses can consider where AI can improve specific workflows or customer interactions, rather than adopting AI tools merely due to rising user counts. The user update from OpenAI was accompanied by a $110 billion investment round and strategic partnerships with Amazon, NVIDIA, and SoftBank.

These developments aim to expand the compute, distribution, and capital needed to meet the growing demand for AI services. While the 900 million milestone does not provide specifics on how users utilize the product or the extent of its impact on business processes, it indicates that conversational AI has reached a scale where businesses can reasonably assume many stakeholders have direct experience with it.
