ChatGPT has reached 900 million weekly active users, according to an announcement from OpenAI on Friday, bringing the AI chatbot close to the 1 billion mark. The company also reported that it now has 50 million paying subscribers, underscoring the rapid commercialization of generative AI tools over the past year.
The updated figure represents a gain of 100 million weekly active users since October 2025, when OpenAI said ChatGPT had reached 800 million. The steady increase highlights continued demand for AI-driven tools across consumer and enterprise markets. OpenAI said subscriber growth accelerated at the start of the year, with January and February on track to become the strongest months for new paid sign-ups in the company’s history.
ChatGPT’s expansion reflects broader shifts in how AI chatbots are being used. OpenAI states that users rely on ChatGPT for writing, research, coding, planning, and productivity tasks. As usage grows, the company claims improvements in response speed, reliability, safety systems, and overall performance. Scaling AI systems, however, also increases infrastructure costs and computational demands, making revenue growth a central focus.
The user milestone was announced alongside news that OpenAI has raised $110 billion in private funding, one of the largest capital raises in the technology sector to date. The round includes reported commitments of $50 billion from Amazon and $30 billion each from Nvidia and SoftBank. The company’s pre-money valuation is said to stand at $730 billion, placing OpenAI among the most highly valued private technology firms globally. The funding round remains open, with expectations of additional participation.
This level of investment reflects both confidence and pressure. OpenAI faces intensifying competition from other AI developers, while also navigating regulatory scrutiny and infrastructure scaling challenges. Training and operating large language models require substantial computing resources, and partnerships with cloud providers and chipmakers have become critical to sustaining growth.
Reaching 900 million weekly active users positions ChatGPT as one of the most widely used AI chatbots worldwide. The question now is whether OpenAI can convert that scale into long-term stability, particularly as enterprise AI adoption expands and consumer expectations rise. With 1 billion weekly users within reach, the company’s next phase will likely hinge on balancing rapid growth with product reliability, cost management, and regulatory compliance.
