The short answer
In 2026, AI search is large and growing but classic Google still dominates. OpenAI has reported ChatGPT usage on the order of 800 million weekly users, AI Overviews appear on a large share of Google results, and roughly 60 percent of searches end without a click. Yet Google still handles over 5 trillion searches a year, many multiples of AI assistant volume.
The Headline Numbers
Figures below reflect 2024 and 2025 published data, the most recent full-year figures available.
By company statements and independent trackers, ChatGPT passed roughly 800 million weekly active users during 2025, making it the fastest adopted consumer software product on record. Google, by its own disclosure, now processes over 5 trillion searches per year, which works out to roughly 14 billion per day. Clickstream analyses estimate Google's search volume still exceeds ChatGPT's search like prompt volume by well over one hundred times.
The correct read is not replacement. It is layering: users are adding AI answers on top of classic search, and both channels now shape what people buy.
AI Overviews Changed Google Itself
The larger disruption in 2025 and 2026 happened inside Google. AI Overviews, launched broadly in 2024, now appear on a substantial share of informational queries, with independent studies placing coverage between roughly 30 and 50 percent depending on category. Where an Overview appears, studies find clicks to websites drop by about a third.
Combined with maps, snippets, and knowledge panels, that pushes the share of Google searches ending without any click to roughly 60 percent per SparkToro's clickstream analysestimates. The zero click majority is the defining statistic of modern search.
Who Uses AI Search and How
Surveys through 2025 found a majority of American adults had used ChatGPT, with usage above 70 percent among adults under 30. Usage skews toward research, comparison, and how to queries, exactly the questions that begin buying decisions. Several commerce analyses also report that visitors arriving from AI assistants convert at rates several times higher than average search visitors, consistent with users arriving after the assistant has already narrowed their choice.
For businesses, the practical statistic is simpler: a growing share of customers now hear a recommendation before they ever see a results page.
What the Numbers Instruct
The definition worth keeping: AI search is the retrieval of answers through systems that generate a synthesized response from many sources, rather than returning a ranked list of links. Winning it requires content that answers questions directly, structured data that machines can verify, and consistent business facts across the web, because engines cite what they can parse and trust.
Classic SEO is not dead; it is the substrate AI engines read. Batch Marketing runs SEO, AEO, and GEO as one program on that basis, optimizing for the ranked list and the synthesized answer at the same time.
Commonly Asked Questions
- Is AI search replacing Google?
- Not by volume. Google still handles over 5 trillion searches a year, many multiples of AI assistant query volume. AI is changing search behavior faster than it is replacing the engine.
- How many people use ChatGPT in 2026?
- Company statements and trackers put ChatGPT at roughly 800 million weekly users, with surveys showing a majority of US adults have tried it.
- Do AI Overviews reduce website traffic?
- Yes. Studies of queries showing an AI Overview find outbound clicks fall by around a third, which is why visibility inside answers now matters alongside rankings.
