For the first time, ChatGPT's share of the AI assistant market in India has fallen below 50%, with Google’s Gemini and Anthropic’s Claude gaining significant traction.

- ChatGPT’s market share dips to 46.4%, Gemini at 27.7%, Claude at 10.3%
- Claude’s global users grow 452% year-on-year, with high subscription conversion
- AI app revenue projected to exceed $4 billion in H1 2026
What happened
ChatGPT, once controlling over half the AI assistant market, has seen its share drop to 46.4% as of May 2026. Google’s Gemini and Anthropic’s Claude have grown rapidly, claiming 27.7% and 10.3% market shares, respectively. This shift reflects a broader trend of users switching between AI platforms in search of features and trust.
Claude’s user base has surged dramatically, experiencing a 452% year-on-year growth globally. Meanwhile, Gemini commands a significant user base with 662 million monthly active users, while ChatGPT retains the largest audience at more than 1.1 billion monthly users. The AI assistant market shows high concentration, with three major players accounting for nearly 90% of usage time.
Why it matters
The changing market shares indicate growing competition, which could drive innovation, better user experiences, and diversified AI capabilities. Claude’s success in monetization, with 13% of users subscribing, highlights shifting consumer willingness to pay for enhanced AI services, especially in mature markets like India and North America.
Consumer spending on AI applications continues to rise, exceeding $4 billion in in-app revenue during the first half of 2026. Yet the pace of new downloads and spending growth is slowing, signaling the AI market is transitioning from rapid expansion to a more stable, competitive phase. Regional market dynamics also diverge, with Asia seeing a dip in downloads despite being the largest market.
What to watch next
Market watchers should monitor how these AI platforms evolve their services and partnerships to capture and retain users. Factors such as trust, privacy policies, and integration with key ecosystems like government or enterprise sectors will likely influence consumer loyalty and platform growth.
In addition to user numbers, the impact of AI on sectors like online shopping and advertising is growing. ChatGPT has started testing ads, reaching 17% of users daily by May 2026, while AI-driven referrals are influencing retail visits across major brands. How AI monetization balances user experience with advertising revenue will be crucial for future market leadership.
