November 9 — According to Business Insider, research by Graphite, a research and growth-marketing firm, based on Similarweb data shows that ChatGPT now accounts for more than 81% of traffic among the world's major AI chatbots, with no competitor holding a market share above 10%. After surging in the first half of 2025, ChatGPT usage plateaued for about seven months before resuming growth this year, with monthly visits up nearly 20% in September to a record 61.35 billion.
