22 AI search statistics for 2026

AI search is the practice of getting answers from a chatbot or an AI-generated summary instead of a list of ten blue links — ChatGPT, Google's AI Overviews, Gemini, Perplexity. Two years ago it was a curiosity. In 2026 it is where a large and fast-growing share of the world starts looking for things.

Most commentary on this shift trades in vibes. This roundup does not. Twenty-two statistics, five categories, every figure attributed to the study, earnings call, or dataset behind it. Where the sourcing was thin, the stat was cut.

The scale of AI search adoption

1. ChatGPT reached 800 million weekly active users

The headline number for the whole category. On OpenAI's Dev Day in October 2025, Sam Altman said ChatGPT had reached 800 million weekly active users (TechCrunch). Fewer than three years after launch, roughly one in ten people on Earth was using it every week.

2. Google's AI Overviews reach about 2 billion monthly users

AI answers are not a niche surface. On Alphabet's July 2025 earnings call, Sundar Pichai said AI Overviews had reached roughly 2 billion monthly users across more than 200 countries and 40 languages — up from about 1.5 billion the prior quarter. For most searchers, an AI-generated answer is now the default first thing they see.

3. Google's Gemini app passed 750 million monthly active users

The standalone assistants are scaling too. In Google's Q4 2025 earnings, the company said its Gemini app had surpassed 750 million monthly active users (TechCrunch), up from 650 million a quarter earlier — 100 million net new users in three months.

4. Perplexity handled about 780 million queries in a single month

The pure-play AI answer engines are compounding fast. CEO Aravind Srinivas said Perplexity processed around 780 million queries in May 2025 — roughly 30 million a day — growing more than 20% month over month (TechCrunch). At that pace Srinivas projected a billion queries a week within a year.

5. ChatGPT's weekly audience doubled in eight months

Growth, not just size, is the story. ChatGPT went from 500 million weekly users in March 2025 to 800 million in October (TechCrunch) — a 60% jump in eight months on an already enormous base. Adoption curves like this do not usually reverse.

Who's actually using it: mainstream, and young

6. 34% of U.S. adults have used ChatGPT — double the 2023 share

Adoption has crossed into the mainstream. A Pew Research Center survey of 5,123 U.S. adults found 34% have used ChatGPT as of early 2025 — roughly double the share in 2023. A third of the adult population is not an early-adopter fringe.

7. 58% of adults under 30 have used ChatGPT

The curve steepens sharply with youth. The same Pew study found 58% of adults under 30 have used ChatGPT, up from 33% in 2023. The buyers and hires of the next decade already treat asking an AI as the default first move.

8. Postgraduates are nearly 3× as likely to use it as high-school-only adults

Adoption skews toward exactly the audiences most brands sell to. Pew found about 52% of adults with a postgraduate degree have used ChatGPT, versus 18% of those with a high-school education or less. Higher income and education correlate with heavier use.

9. 58% of users encountered an AI Overview in a single month

Even people who never open a chatbot are seeing AI answers. Pew's analysis of nearly 69,000 real searches found that 58% of participants ran at least one search that produced an AI summary during March 2025. Exposure is now nearly universal among active searchers.

How search behavior is shifting to answers

10. About one in five Google searches now returns an AI summary

The surface is mainstream and growing. Pew found that about 18% of Google searches — roughly one in five — produced an AI-generated summary in March 2025. For informational and how-to queries, the share is materially higher.

11. Clicks fall to 8% when an AI Overview appears, versus 15% without

The AI answer changes what people do next. Pew measured a click on any traditional result just 8% of the time when an AI summary was shown, against 15% when it was not — roughly half the click-through. The answer increasingly ends the journey on the results page.

12. Only 1% of users click a source inside the AI Overview

Being cited is not the same as being visited. Pew found that only about 1% of visits to a page with an AI summary involved clicking a link inside that summary. The value is shifting from the click to the mention — the whole case for optimizing to be named in the answer.

13. Users end their session 26% of the time after an AI summary

Answers satisfy and close the loop. Pew found people ended their browsing session on 26% of pages that showed an AI summary, versus 16% of pages without one. The AI answer is doing the job the destination page used to do.

AI referral traffic is the fastest-growing channel

14. Generative-AI referral traffic to retail grew about 12× in seven months

The trickle is becoming a stream. Adobe found generative-AI referral traffic to U.S. retail sites grew roughly 12× between July 2024 and February 2025. It is still a small share of total sessions for most sites — but it is the fastest-growing share.

15. AI-referred visitors view 12% more pages and stay 41% longer

The traffic is not just growing — it is better. Adobe found AI-referred visits generate about 12% more page views and last 41% longer than non-AI visits. Visitors who arrive from an AI answer show up more engaged, because the chatbot pre-qualified them.

16. The AI-traffic conversion gap narrowed from 43% to 9%

The quality gap is closing fast. In July 2024 Adobe found AI-referred visitors were 43% less likely to convert than other traffic; by February 2025 that gap had shrunk to just 9%. AI referrals are maturing into a commercial channel, not just a curiosity.

17. AI now sends about 0.3% of all web traffic — up roughly 16× from 2024

Zoom out and the trajectory is unmistakable. SE Ranking's cross-site analysis found AI platforms account for around 0.3% of all website traffic, up from roughly 0.02% in 2024 — an order-of-magnitude climb in two years. Small today, but the second derivative is what matters.

Where marketers are putting the money

18. 94% of CMOs plan to increase AEO/GEO budgets in 2026

Budgets are following behavior. Conductor's CMO research found 94% of marketing leaders plan to increase their AEO and GEO budgets in 2026. Near-unanimous intent to spend more is rare in any channel, let alone a two-year-old one.

19. The average enterprise now puts ~12% of digital spend into AEO

It is real money, not a test line item. The same Conductor report found the average enterprise allocates about 12% of its digital marketing spend to answer engine optimization. AI visibility has graduated from experiment to standing budget.

20. 97% of CMOs report a positive impact from AEO

Spending is being validated by results. Conductor found 97% of CMOs reported a positive impact from AEO in 2025 — the reason the 2026 budget numbers look the way they do. This is not hope; it is reinvestment.

21. Recurring AI-workflow adoption climbed from 51% to 87% of teams

AI has moved from pilot to plumbing inside marketing orgs. Tracked data shows recurring AI-workflow adoption rose from 51% in Q1 2024 to 87% in Q1 2026 (Omnibound, citing Salesforce). Optimizing for AI search is now happening inside teams that already run on AI day to day.

22. Mid-market AI tool spend jumped 183% in a single year

The acceleration shows up in dollars, fast. Median mid-market AI tool spend rose 183% in one year, from about $1,200 to $3,400 per month (Omnibound) — among the sharpest single-year budget jumps in any marketing-technology category. The window to build an AI-search advantage cheaply is closing.

The through-line across all twenty-two: AI search is no longer a forecast. Billions of people are already using it, the audience skews toward exactly the buyers brands care about, the referral traffic is growing fast and converting better every quarter, and the budget is moving to match. The brands treating AI-search visibility as an operating discipline today are the ones getting named in the answer while everyone else debates whether it is real.
