Google's Gemini AI Assistant Nears One Billion Users, Tripling Growth in a Year

Gemini's Rapid User Growth

Google announced during its Q2 2026 earnings call that its AI assistant, Gemini, has surpassed 950 million monthly users. This represents a tripling of its user base compared to the previous year, when it had crossed 750 million monthly active users in February.

The rapid expansion of Gemini's user base positions it as a significant competitor to OpenAI's ChatGPT, which reached 1 billion monthly active users in June. Google attributes this growth to new agentic features like Daily Brief and the personalized agent, Gemini Spark, which are available in the U.S. and internationally.

Cross-Platform Adoption and Market Share

Gemini's adoption extends beyond Android, with a strong user base on iOS. The app has been downloaded over 137 million times on iOS in the last 12 months, partly due to features like the Nano Banana image generation model.

According to Sensor Tower's "State of AI" report for H1 2026, ChatGPT's market share among AI assistants fell below 50% for the first time, while Gemini's share increased to 27.7%.

Impact on Google Search

Despite the rise of AI assistant apps as a substitute for search, Google reported continued strength in its search vertical, partly due to an AI-centric overhaul. The Q&A-style AI mode in Google Search has also crossed 1 billion users this quarter, driving an incremental increase in search queries.

Google noted that hardware engineering efforts have reduced the cost of its AI mode, even with the introduction of new models and features.

Future Implications

The significant growth of Gemini and the integration of AI into Google Search indicate a broader shift in how users interact with information and digital assistants. This trend suggests increasing competition in the AI assistant market and a continued evolution of search functionalities driven by AI.
