Sensor Tower data shows ChatGPT’s AI assistant share dropped to 46% in May, while Google Gemini and Claude rose to 28% and 10%, respectively.
ChatGPT’s dominance in the AI assistant market slipped below 50% for the first time in March, ending May at 46% share, according to new data. The decline marks a shift as competitors gain traction in the rapidly expanding sector.
Google Gemini now holds 28% of the market, while Anthropic’s Claude climbed to 10%. Despite the drop, ChatGPT remains the fastest app to reach 1 billion monthly users, surpassing TikTok and Instagram. OpenAI is pivoting toward a superapp model ahead of its planned IPO.
The data underscores the end of ChatGPT’s near-monopoly as alternatives attract users. Web traffic share for ChatGPT fell from 77.6% to 53.7% over the past year, reflecting broader competition.
