Together, ChatGPT and Gemini accounted for 81.4% of the tracked website visits. Claude followed in third place, with the remaining services accounting for smaller individual shares.
1. ChatGPT Remains the Leading AI Chatbot
ChatGPT continues to dominate AI chatbot website traffic. It received approximately 5.9 billion website visits in September 2026, representing 56.4% of the tracked total. <Cite refs={[“turn726647search0”]}/>
Its popularity comes from its broad range of uses. People turn to ChatGPT for writing assistance, explanations, brainstorming, coding, studying and everyday questions.
Businesses also use AI assistants to support research, customer communication and content workflows. This wide range of applications helps explain why ChatGPT continues to attract substantial traffic.
However, its share of the overall chatbot website traffic has declined compared with October 2025. That does not mean its website traffic has necessarily fallen. The reported figures show that ChatGPT received about 5.7 billion visits in January 2026 and around 5.9 billion in September. <Cite refs={[“turn726647search0”]}/>
The distinction matters: a platform can attract more visits while losing market share if its competitors grow faster.
2. Google Gemini Continues to Challenge ChatGPT
Google Gemini ranked second, attracting approximately 2.6 billion website visits in September 2026. Its share reached 25.0%, up from 13.6% in October 2025. <Cite refs={[“turn726647search0”]}/>
One potential advantage for Gemini is its connection with Google’s wider technology ecosystem. People already using Google services may find it convenient to explore its AI assistant alongside their existing digital tools.
Gemini can help users draft content, understand information, summarise material and work through everyday questions. Google has also continued developing its AI products, helping maintain attention on the platform.
Although Gemini remains behind ChatGPT in website traffic, its growth shows how quickly the competitive landscape can change.
3. Claude Records One of the Biggest Gains
Claude, developed by Anthropic, ranked third in September 2026, with approximately one billion website visits and 9.6% of tracked chatbot traffic. Its share was 2.3% in October 2025. <Cite refs={[“turn726647search0”]}/>
Claude has attracted attention for its capabilities in coding, document analysis, writing and knowledge-intensive work. These uses make it relevant to developers, professionals, researchers and businesses.
Its growth is particularly notable because it moved from fifth place in October 2025 to third place in September 2026. According to Visual Capitalist’s analysis, Claude’s website traffic had increased substantially over that period. <Cite refs={[“turn726647search0”]}/>
The trend suggests that users are exploring alternatives rather than relying on a single AI assistant for every task.
4. DeepSeek, Grok and Microsoft Copilot Remain in the Rankings
Several other AI chatbots continue to attract substantial audiences, although their website traffic shares are smaller.
DeepSeek ranked fourth, with approximately 356 million visits and a 3.4% share. It has drawn attention for its AI models and their applications in reasoning and technical tasks.
Grok, developed by xAI, ranked fifth with around 241 million visits and a 2.3% share. It offers conversational AI features and has a connection with the X social platform.
Microsoft Copilot ranked sixth, with an estimated 157 million visits and a 1.5% share. It is designed to assist users with tasks such as writing, information retrieval and productivity.
These figures count visits to the respective chatbot websites. They do not capture all usage through mobile applications, APIs or AI features integrated into other products. In particular, the reported Copilot website share does not measure all Copilot usage inside Microsoft products. <Cite refs={[“turn726647search0”]}/>
5. Why Is the AI Chatbot Market Changing?
The rankings show that competition is increasing as AI services develop new capabilities and reach more users.
Several factors can influence a chatbot’s growth:
- Product improvements: Better answers, reasoning and coding assistance can encourage users to return.
- Ease of access: Integration with existing apps and services can make an AI tool more convenient.
- Specialised features: Some users prefer tools designed for research, programming or particular professional tasks.
- Public awareness: Product launches, media coverage and marketing can introduce chatbots to new audiences.
- User experience: Speed, reliability, privacy controls and ease of use can influence which service people choose.
Website traffic alone cannot explain why every user chooses a particular platform. However, changes in traffic share can provide useful clues about how interest in these products is evolving.
6. Does Website Traffic Tell Us Which AI Chatbot Is Best?
Not necessarily. The most visited AI chatbot is not automatically the best choice for every person or task.
Website visits measure activity on a platform’s website, rather than the number of unique people using it. They also exclude some activity through apps, APIs and features embedded in other services.
For example, a student might prefer one chatbot for explanations, while a developer might choose another for coding. A business may prioritise security, integration or administrative controls over general popularity.
When comparing AI chatbots, users should consider answer quality, available features, pricing, privacy policies and how well each tool handles their specific needs.
The rankings are therefore best understood as a measure of web traffic rather than a definitive assessment of AI quality.
What Does the Future Hold for AI Chatbots?
The September 2026 figures suggest that ChatGPT remains the main destination for AI chatbot website traffic, while Gemini and Claude have gained ground.
Future competition may increasingly depend on how effectively these services support real-world tasks, integrate with existing products and earn users’ trust.
New features and model improvements could change the rankings again. Smaller services may also find opportunities by focusing on specialised audiences or offering capabilities that larger platforms do not prioritise.
For users, increased competition may bring more choices and encourage providers to improve their products. The longer-term outcome will depend on how these tools develop and how people choose to use them.
Conclusion
The most used AI chatbots in 2026 show a market led by ChatGPT, followed by Google Gemini and Claude. September website traffic data places ChatGPT at 56.4%, Gemini at 25.0% and Claude at 9.6% of tracked visits. <Cite refs={[“turn726647search0”]}/>
Although ChatGPT remains the leader, the growth of Gemini and Claude highlights the changing nature of the AI industry. DeepSeek, Grok, Microsoft Copilot and Perplexity also remain part of the competitive landscape.
Ultimately, website traffic is only one way to measure an AI chatbot’s reach. For users choosing between these services, the most useful platform will depend on their goals, preferred features and individual requirements.
