AI search statistics for 2026
27 figures on how people use ChatGPT, Gemini and Google's AI features, and what it means for clicks, traffic and sales. Every number links to its source.
By the Variask team · Updated
Key takeaways
- AI assistants are now mainstream: ChatGPT passed 900 million weekly users and the Gemini app passed 1 billion monthly users.
- Most people meet AI answers inside Google, through AI Overviews and AI Mode.
- AI answers mean fewer clicks to websites, so being named and cited inside the answer matters more.
- AI referral traffic is still small, but it grows fast and converts well, especially in retail.
How many people use AI assistants
The biggest assistants now reach hundreds of millions of people every week. Note that companies report different measures: OpenAI uses weekly users and Google uses monthly users, so the numbers are not directly comparable.
900M+
weekly active users on ChatGPT, announced by OpenAI, up from 800 million in October 2025.
50M+
paying ChatGPT subscribers, announced at the same time.
950M
monthly active users on the Gemini app, with daily active users tripling over the past year.
1B+
monthly active users on the Gemini app, reported in Alphabet's Q3 2026 earnings materials.
49%
of US adults say they use AI chatbots, up from about a third in 2024.
About 1 in 4
US adults use chatbots daily, including 12% who use them several times a day.
Which assistants people use
ChatGPT still leads by a wide margin in the US, but Gemini's share of AI web traffic has grown fast.

76% to 53%
ChatGPT's share of worldwide generative AI website visits fell over twelve months as Gemini and others grew.

Google's AI features

1B+
monthly active users of AI Mode in Google Search since it expanded globally.
2.5B+

18%

Clicks and zero click search
When AI answers the question on the results page, fewer people click through. Being named and cited in the answer matters more as a result.
8% vs 15%
Google users clicked a traditional result in 8% of visits when an AI summary appeared, versus 15% when it did not.
1%
of visits with an AI summary led to a click on a link inside the summary itself.
26% vs 16%
of sessions ended on the results page when an AI summary appeared, compared with those without one.
58%
lower click through rate for the top ranking page on keywords that show an AI Overview, up from 34.5% in the same study a year earlier.
25%
drop in traditional search engine volume by 2026 was Gartner's well known 2024 prediction, as people move to AI chatbots and agents.
AI referral traffic to websites
AI still sends a small share of total website traffic, but it is growing fast and the visitors tend to arrive ready to act.
0.32%
of all website traffic came from AI platforms in 2026, up from 0.24% in 2025 and 0.02% in 2024.
74.78%
of AI referral traffic came from ChatGPT, followed by Gemini at 11.56%, Perplexity at 7.23%, Copilot at 3.51% and Claude at 2.62%.
6.8%
of US ChatGPT prompts included citations by May 2026, up from about 1.6% in June 2025.
AI and online shopping
Retail is where the value of AI traffic shows most clearly.
693.4%
increase in traffic from generative AI tools to US retail sites in the 2025 holiday season, compared with the year before.

What this means for brands
- Track whether AI names your brand, not only where you rank. A top ranking now earns fewer clicks when an AI answer sits above it.
- Make sure AI search crawlers can read your site, and that your key pages answer buyer questions directly.
- Measure AI referral traffic as its own channel. It is small but growing, and it often converts well.
- Do not rely on one engine. ChatGPT leads, but Gemini and Google's AI features reach huge audiences too.
