According to the latest report from Sensor Tower, OpenAI's ChatGPT has lost control of more than half of the market for the first time, with its share falling below 50%. This decline is attributed to the rapid growth of alternative chatbots such as Google's Gemini, Anthropic's Claude, and xAI's Grok. Despite this, it's important to note that in early June, ChatGPT was recognized as the fastest-growing app in the world, reaching an impressive milestone of 1 billion monthly users. Since February of this year, OpenAI's user base has grown by 200 million, highlighting its significance in the market even amidst increasing competition.
