ChatGPT's Market Share Slips Below 50% for the First Time

Original: ChatGPT’s market share slips below 50% for first time

ChatGPT loses majority market share for the first time, though it still leads with over 1.1 billion monthly users.

For the first time since its launch, ChatGPT's share of the global AI assistant market has fallen below 50%, marking a notable competitive shift. The platform remains the clear market leader with over 1.1 billion monthly users, but rivals have grown substantially. Google's Gemini now claims 662 million monthly users and Anthropic's Claude reaches 245 million, together eroding ChatGPT's once near-total dominance.

For the first time since OpenAI's ChatGPT became the dominant conversational AI platform, its global market share in the AI assistant space has slipped below the 50% threshold — a symbolic and potentially strategic inflection point for the broader industry. The milestone underscores how rapidly the competitive landscape has shifted as rival platforms from Google and Anthropic have scaled their user bases to hundreds of millions.
