After Seven Months of Stagnation, a New Peak at 61.35 Billion in September

The use of ChatGPT saw significant growth during the first half of 2025, followed by a seven-month plateau. This year, growth has resumed, with a monthly increase of nearly 20% and a record of 61.35 billion visits in September, according to Graphite. Earlier in the year, ChatGPT's dominance seemed to wane in the face of rising competition from Google and Anthropic, but the study indicates a return to growth. Additionally, Katie Notopoulos reports that ChatGPT has 1.2 billion weekly users.

Competitors Rising from a Small Base and Measurement Methodology

Claude has experienced what can be described as extraordinary growth over the past year, and Gemini has expanded rapidly, but these advances start from volumes much lower than those of ChatGPT. Graphite uses web and mobile traffic measurements, as well as flows to and from major AI services, based on data from Similarweb. Ethan Smith led the study. In this context, Google’s Gemini and Anthropic’s Claude are often cited as potential threats to OpenAI, whose CEO is Sam Altman.
