In a sweeping conquest of the AI chatbot arena, OpenAI’s ChatGPT has secured a commanding 80.92% market share as of mid-2025. Such dominion leaves competitors like Perplexity and Microsoft Copilot in the dust, struggling to chip away at ChatGPT’s lead. According to TechRadar, ChatGPT’s market share peaked at a staggering 84.2% earlier in the year, showcasing remarkable staying power.
The Rise and Fall of Perplexity
Perplexity once emerged as a potential contender, reaching a market share peak of 14.1% in March 2025. However, its influence waned, dropping to 8.0% by mid-year. Despite efforts to differentiate through research-driven AI tools and live data integration, it seems the allure of innovation alone isn’t enough to rival ChatGPT’s vast ecosystem.
Microsoft Copilot’s Steady Climb
Microsoft’s Copilot, though starting behind, has proven resilient. From a modest 0.3% market share in March, it has stabilized around 4-5% through strategic Office and Windows integration. While still far from ChatGPT’s shadow, Copilot’s consistent growth positions it as a budding challenger, hinting at a future rivalry with Perplexity for the second spot.
Small Rivals in a Vast Ocean
Other contenders like Google Gemini and Deepseek find themselves grappling for relevance. With Google Gemini hovering between 1.9% and 3.3%, and Deepseek peaking at 2.7%, the battle for market presence is fierce yet fragmented. Anthropic’s Claude, at best a niche player, remains an outlier.
The Path Ahead
The chatbot market, while dynamic, is heavily skewed towards the behemoth that is ChatGPT. Competitors are forced to innovate rapidly or rethink integration strategies to pose a genuine threat to OpenAI’s dominance. As trends evolve, Microsoft’s systematic integration approach with Copilot could herald a shift in balance, but for now, ChatGPT’s reign continues unchallenged.
In essence, while the AI chatbot market buzzes with potential disruptions, ChatGPT’s colossal footprint remains, an influential sovereign in the world of conversational agents.
