On May 27, 2026, Edison Research at SSRS published a data point that should stop every marketer mid-scroll.
65% of American adults used at least one AI platform in the week of May 14-18, 2026. That is 175.5 million people. Three months earlier, in February, that number was 52%.
In 90 days, 36 million more Americans became weekly AI users.
To put that in perspective: Edison Research noted it is difficult to identify any recent media platform or technology that experienced comparable growth in an equivalent period. That is not hype. That is the research firm’s own language, sourced from a probability-based national panel of over 1,000 adults.
What Actually Happened
This was not a viral moment or a one-week spike. Edison Research conducts this survey twice a month on the SSRS Opinion Panel Omnibus, using probability-based sampling that includes telephone interviewing for non-internet users. This is as close to a ground-truth headcount as consumer media research gets.
The February baseline was already striking: more than half of American adults using AI weekly. The May figure confirms what that baseline was pointing toward.
“AI User Metrics shows that Americans are increasingly incorporating AI into their personal lives.” — Megan Lazovick, VP, Edison Research at SSRS
The platform breakdown is where it gets strategically interesting. ChatGPT from OpenAI holds the lead at 43% weekly reach, up from 36% in February. Google Gemini recorded the fastest individual-platform growth of any tool tracked, surging from 25% to 38% in three months. Claude from Anthropic doubled its weekly users, moving from 4% to 9%, while its awareness among American adults jumped from 21% to 42% over the same period.
Why This Hits Different for Marketers
The practical consequence is one that most marketing strategies have not yet caught up with: your audience is spending meaningful time inside AI interfaces every single week, and most of that time is personal, not professional.
63% of weekly AI users used it for personal purposes. 33% used it for business. That personal-use dominance means the people you are trying to reach are asking ChatGPT and Gemini questions about products, services, travel, finance, and health long before they ever open a search engine.
If your brand is not being cited in AI answers, you are missing the top of a funnel that now reaches two thirds of the US adult population.
The before-and-after for content marketers is concrete. Before: optimize for Google rankings, build backlinks, write for featured snippets. After: do all of that, and also ensure your content is structured, authoritative, and citable enough that AI systems surface it when someone asks a relevant question. The Gemini growth number matters specifically here. Google’s AI surfaces, including Gemini and AI Mode in Search, are growing faster than any competitor. That is where organic distribution is being rebuilt.
There is a referral traffic signal pointing the same direction. Since OpenAI began surfacing more prominent outbound links in ChatGPT answers, publisher referral traffic from the platform is up 150%, with pages-per-visit up 24% and time on site up 11%. Users arriving from AI are more engaged than users arriving from most traditional channels. The monetizable audience is shifting toward AI-referred traffic faster than most analytics dashboards are showing it.
What to Do This Week
First, run an AI visibility audit on your own content. Ask ChatGPT, Gemini, and Claude the five questions your ideal customer is most likely to be asking in your category. If your brand or content is not appearing in the answers, that is your gap. Treat it the way you would treat a first-page search ranking you are not holding.
Second, update your content strategy to include explicit AI-citation signals. That means authoritative, well-sourced long-form content, clean structured data markup on your site, and regular coverage in the publications and domains that AI systems cite most frequently. Edison Research’s data shows Claude’s awareness doubled in three months partly on the back of a Super Bowl campaign. Brand-level awareness drives AI-platform discovery more directly than most marketers have modeled.
Third, if you are allocating paid media budget for the second half of 2026, reserve a test budget for ChatGPT Ads. OpenAI opened its self-serve Ads Manager to all US businesses on May 5, dropped the minimum spend entirely, and added geo-targeting down to ZIP code level in the same month. The platform now reaches a weekly audience of 43% of American adults. The CPC starting bid is $3 to $5. That is early-market pricing for a surface that is already at scale.
The gap between where your audience spends attention and where your marketing budget is allocated is widening by the month. The Edison Research data quantifies how wide it has already become.
