OpenAI’s ChatGPT has seen its global market share drop below 50 percent for the first time, falling to 46.4 percent, as various AI chatbots—including Google Gemini—rapidly gain popularity. However, ChatGPT still retains the top position.

The world of Artificial Intelligence (AI) chatbots has witnessed a clash of various tools, and the competition has now become more exciting than ever. ChatGPT, which reigned supreme as the king of AI tools for a long time, is facing a stiff challenge for the first time. According to the latest reports, OpenAI’s ChatGPT has seen its market share drop below 50 percent for the first time. Meanwhile, Google’s Gemini has rapidly emerged as its biggest competitor.
According to Sensor Tower’s ‘State of AI Report 2026’, ChatGPT’s global market share fell to 46.4 percent by the end of May 2026. This marks the first time ChatGPT has failed to retain a grip on more than half the market. However, this does not mean the number of ChatGPT users has declined; rather, the entry of new players and their rising popularity in the AI chatbot market has led to a fragmentation of the total market share.
ChatGPT Remains the Most Popular Tool
ChatGPT continues to be the world’s most popular AI chatbot. The report indicates it has over 1.1 billion monthly active users. This figure demonstrates that OpenAI’s platform remains the top choice for millions of people. However, users now have far more options than before, intensifying the competition.
Google’s Gemini is considered the primary driver of this shift. Over the past few years, Google has deeply integrated Gemini into many of its products and services. Its presence across platforms like Android smartphones, Google Search, Gmail, and Workspace has brought Gemini to millions of new users, enabling it to rapidly expand its market share.
Growing Influence of Other Companies
It is not just Gemini; platforms such as Anthropic’s Claude, Elon Musk’s xAI (Grok), Perplexity, DeepSeek, and Meta AI are also consistently attracting new users. These companies have developed their AI models with specific needs and use cases in mind. While some are emphasizing superior research capabilities, others are attracting users through real-time information and rapid responses.
Experts believe the AI industry has reached a stage where it will be difficult for any single company to maintain dominance. Although ChatGPT initially brought AI chatbots into the mainstream, the market is now expanding, and competition is intensifying. This is likely to provide users with more choices and better features.
India: A Key Market for OpenAI
Significantly, India has emerged as a crucial market for OpenAI. OpenAI CEO Sam Altman recently revealed that ChatGPT has approximately 100 million weekly active users in India. India is considered the company’s second-largest market, trailing only the United States. Consequently, competition among AI companies for Indian users is expected to heat up further, and it is almost certain that users will directly benefit from this.
