The AI chatbot race has heated up in 2025 with more players entering the scene and shaking up the market. But despite the rising competition, and people having more chatbot options than ever, ChatGPT remains the top choice in Large Language Models.
Large language models are advanced artificial intelligence systems trained on vast amounts of text data to understand, generate, and process human language.
According to data presented by Jemlit.com, ChatGPT’s market share surged to 82.6% in July, nearly five times larger than its five biggest competitors combined.
As the pioneer in this market, ChatGPT has long been a key in transforming generative AI into a multi-billion-dollar business. Nearly three years after its launch, OpenAI remains the biggest player in the space.
Alternative platforms like DeepSeek and Perplexity have contributed to growth in the AI chatbot market, and they have pushed OpenAI to roll out updates. ChatGPT remains the top choice for most people using generative AI daily (based on StatCounter data).
After losing nearly 5% of the global market between April and July, ChatGPT’s market share jumped by almost 3% in a single month, reaching 82.6% in July. That means OpenAI’s chatbot holds nearly five times the market share of its five biggest competitors, Perplexity, Microsoft Copilot, Google Gemini, DeepSeek, and Claude, combined.
The regional data shows an even stronger dominance. For instance, in Europe, ChatGPT now holds 85.66% of the market, up 1.5% in a month but still below 90% it had in April. Other countries and regions also reported growth.
In the U.S. ChatGPT held 80.1% of the market in July, rising by a solid 2.2% month-over-month. Asia saw an even bigger gain, with ChatGPT’s share jumping from 77.6% in June to 81.1% in July.
While many have questioned ChatGPT’s dominance amid rising competition, Statcounter data show OpenAI is actually growing its market share as others lose ground. While its market share jumped by nearly 3% month-over-month, Perplexity, Microsoft Copilot, Google Gemini, and Claude have all reported losses.
The data shows that Perplexity, the second-largest player in the AI chatbot space, held just over 8% of the market in July, significantly down from the 11% share it had a month before. Microsoft Copilot dropped by 0.24%, now holding only 4.59% of the market, while Google Gemini remained flat at 2.19%. Anthropic’s chatbot, Claude, also slipped from 1.11% to 0.91%.
On the other hand, the youngest player in the industry, DeepSeek, is the only ChatGPT alternative whose market share increased in this period, rising from just over 1% share in June to 1.63% in July, and proving that the Chinese chatbot continues to eat into the market share of other players.
