ChatGPT reigns sovereign in the AI chatbot market share as Microsoft Copilot catches up on Perplexity (www.techradar.com)

New data from StatCounter reveals that OpenAI’s ChatGPT continues to dominate the global AI chatbot market, commanding over 80% of worldwide usage from July 2024 to August 2025. Despite a slight dip from its April 2025 peak of 84.2%, ChatGPT’s overwhelming scale and broad ecosystem maintain a clear lead far ahead of any competitor. This consolidation highlights ChatGPT’s strong user retention and market influence in an increasingly competitive landscape. Perplexity, ChatGPT’s closest rival, peaked at 14% market share in early 2025 but has since seen a decline, struggling to maintain consistent adoption despite its focus on research-driven tools and live data integration. Meanwhile, Microsoft Copilot has emerged as a notable challenger by leveraging deep integration across Office and Windows applications, growing rapidly from 0.3% in March 2025 to a steady 4-5% share. This growth trajectory positions Copilot as a potential second-place contender as it capitalizes on enterprise AI adoption. Other players like Google Gemini and Anthropic’s Claude remain marginal, underscoring a market that is dynamic but heavily concentrated around a few dominant platforms. The report underscores how AI chatbot adoption is increasingly shaped by ecosystem integration and scale rather than novelty alone. Microsoft’s strategy of embedding AI into workplace tools suggests that future market shifts may hinge on enterprise-focused AI offerings, while OpenAI’s early lead continues to set industry standards for chatbot usage worldwide.
