The conversational AI market has fragmented. ChatGPT still dominates with over 80% market share, but its competitors are gaining ground. And above all: each platform has its own particularities, preferred sources, and citation criteria.
For an effective AI visibility strategy, it's no longer enough to think "ChatGPT". You need to understand the complete ecosystem: who the players are, what their specificities are, and which ones really matter for your audience.
This overview details the five essential platforms of 2025, with the data that matters: users, market share, citation behavior, and implications for your visibility.
The state of the market in 2025
The landscape has evolved considerably since ChatGPT emerged in late 2022. While OpenAI remains largely dominant, competition has intensified and structured around differentiated positions.
AI chatbot market share - 2025
Claude from Anthropic, with about 3% consumer market share, occupies a unique position: dominant in the enterprise segment (32% B2B market share), but discrete on the consumer side. This dichotomy illustrates well the ongoing segmentation.
Figures vary by source and measurement method, but the trend is clear: the market is fragmenting. ChatGPT has lost points to specialized competitors. And this fragmentation implies diversifying visibility efforts.
ChatGPT: the unavoidable giant
ChatGPT (OpenAI)
ChatGPT remains the market reference. 800 million weekly users, over 2 billion daily queries. It's the entry point for most users into conversational AI.
Citation behavior: ChatGPT relies on Bing for real-time search. 87% of cited sources correspond to Bing's top 10. Wikipedia represents nearly 8% of total citations — the most frequently mentioned source.
Visibility strengths:
- Massive user volume — being cited here maximizes exposure
- Connection to Bing — Bing positioning transfers directly
- Media partnerships (AP, Reuters, Axel Springer) — these sources are prioritized
What matters to appear there: Strong domain authority, Bing positioning, structured content with answer capsules, presence on OpenAI partner sources.
Claude: the professional choice
Claude (Anthropic)
Claude has an atypical profile: 3% consumer market share, but 32% of the enterprise market — surpassing OpenAI on this segment. It's the preferred model for developers and regulated sectors.
Citation behavior: Claude favors technical sources and official documentation. Strong overlap with GitHub, Stack Overflow, Notion, and Figma. Excellent for long document analysis — particularly appreciated in legal and financial sectors.
Visibility strengths:
- Dominant in enterprise — if your target is B2B, Claude counts as much as ChatGPT
- Preferred for technical tasks — IT sector, development, consulting
- Over 60% of Fortune 500 companies have experimented with it
What matters to appear there: Quality technical documentation, presence on developer platforms, in-depth and structured content, demonstrated sector expertise.
Gemini: Google integration
Gemini (Google)
Gemini benefits from the Google ecosystem. 450 million monthly users, integrated into Android, Google Workspace, and progressively into Google Search via AI Overviews.
Citation behavior: Gemini logically relies on Google's index. AI Overviews — which use Gemini technology — cite 97% of their sources from Google's top 20. The synergy between classic SEO and Gemini visibility is direct.
Visibility strengths:
- Native integration into the Google ecosystem — automatic massification
- AI Overviews extend its reach on traditional search
- Strong adoption on mobile (Android)
What matters to appear there: Classic Google SEO positioning, schema.org structured data, presence in the Knowledge Graph, solid E-E-A-T content.
Perplexity: the search specialist
Perplexity
Perplexity has positioned itself as an "answer engine" rather than a generalist chatbot. 22 million users, 780 million monthly queries — a threefold increase in less than a year.
Citation behavior: Perplexity systematically cites its sources, with clickable links. It favors specialized publications, studies, sites with strong topical authority. Very "research"-oriented format with inline citations.
Visibility strengths:
- Systematic citations with links — generates direct traffic
- Research and professional-oriented audience
- Values original data and analyses
What matters to appear there: Factual and sourced content, proprietary data, specialized publications, demonstrated expertise in the field.
Copilot: Microsoft's integrated AI
Copilot (Microsoft)
Copilot is everywhere in the Microsoft ecosystem: Windows 11, Edge, Office 365, Teams. About 14% market share, with massive enterprise adoption via Microsoft 365 licenses.
Citation behavior: Copilot uses Bing as a source, similar to ChatGPT. Integration into productivity tools (Word, Excel, PowerPoint) makes it a daily contact point for professionals.
Visibility strengths:
- Integration into daily workflows — contextual exposure
- Strong enterprise adoption via M365 licenses
- Synergy with Bing positioning
What matters to appear there: Same levers as ChatGPT — Bing positioning, domain authority, structured content.
New entrants to watch
Beyond the five leaders, several players deserve attention:
DeepSeek emerged in early 2025 with a high-performing open source model. About 1.6% market share, but rapid growth and strong adoption in Asia.
Grok (xAI / X) benefits from integration with the X platform (formerly Twitter). Differentiating positioning on current events queries and political topics.
Meta AI is progressing via integration into Facebook, Instagram, and WhatsApp applications. The potential user base is massive, even if adoption remains limited.
These platforms don't yet represent significant volumes for most companies, but they illustrate the market fragmentation dynamic.
Implications for your visibility strategy
Market diversification has several practical consequences.
1. Prioritize according to your audience
If your target is general B2C, ChatGPT remains the absolute priority. If you're targeting professionals or businesses, Claude deserves as much attention. For tech and developer audiences, presence on Claude and Perplexity becomes strategic.
2. Identify synergies
ChatGPT and Copilot use Bing — optimizing for Bing covers 74% of the market. Gemini and AI Overviews use Google's index — your classic SEO transfers directly. These synergies allow optimizing effort.
3. Adapt format to channel
Perplexity values data and citations. Claude appreciates in-depth technical content. ChatGPT favors short, standalone answer capsules. The same topic may require different treatments depending on target platforms.
4. Measure by platform
Your visibility can vary considerably from one AI to another. Regular audits on different platforms help identify weak points and adjust strategy.

Launch a multi-AI auditEvolutions to anticipate
Several trends will shape the landscape in the coming months:
Increasing workflow integration. Conversational AIs are increasingly integrating into daily tools — web search, productivity, content creation. The brand contact moment shifts from intentional search to contextual assistance.
Sector specialization. Vertical AIs are emerging for specific sectors — healthcare, legal, finance. These specialized platforms could become priority visibility channels for certain markets.
Content partnership evolution. Agreements between AI platforms and content publishers are multiplying. These partnerships modify preferred sources and create new visibility opportunities.
Search-conversation convergence. The boundary between traditional search engines and conversational AI is blurring. Google integrates Gemini, Bing integrates ChatGPT. Eventually, the distinction could become obsolete.
Key takeaways
The conversational AI market is no longer monolithic. ChatGPT dominates, but five major platforms now matter for business visibility.
Each platform has its specificities: preferred sources, citation format, typical audience. An effective AI visibility strategy takes these differences into account rather than treating "AI" as a homogeneous block.
Synergies exist and allow optimizing effort. Bing covers ChatGPT and Copilot. Google covers Gemini and AI Overviews. A structured approach can maximize impact without multiplying work.
Fragmentation will continue. New players emerge, existing ones specialize. Monitoring this landscape and adapting strategy becomes a skill in itself.
