Claude’s Consideration score (the share of people who say they would consider buying from a brand the next time they are in the market) among U.S. Gen Z adults hit 28.1% in Q2 2026, up from 14.2% the prior quarter, landing the highest score of any brand in YouGov’s newest BrandIndex ranking. OpenAI climbed from 10.1% to 22.1% in the same period. Two AI companies now sit in the same quarterly brand-tracking table as Johnnie Walker and REI. The complication: a separate YouGov 19-market survey on search behavior found U.S. trust in AI assistants at just 28%, a full 42 percentage points below the trust consumers place in traditional search engines.
How Fast Did Gen Z AI Brand Consideration Actually Grow?
YouGov BrandIndex tracks more than 2,000 brands daily and ranks the ten fastest quarter-over-quarter improvers in Consideration. Reuben Staines, YouGov America’s head of marketing, shared the Q2 2026 analysis with Search Engine Journal. The ranking is titled “Brands Rising Among Gen Z in the U.S. in 2026.” Among the notable findings: two AI companies landed in the same table as consumer staples and lifestyle brands that had nothing to do with technology.
- Claude (Anthropic): 14.2% to 28.1%, the highest Consideration score of any brand in the ranking (YouGov BrandIndex, Q2 2026)
- OpenAI: 10.1% to 22.1% (YouGov BrandIndex, Q2 2026)
- ChatGPT (tracked separately from OpenAI in BrandIndex): 16.3% to 25.4%, a gain of more than 50% (YouGov BrandIndex, Q2 2026)
- Johnnie Walker: 7.5% to 20.0%, driven by a refreshed “Keep Walking” campaign across streaming, social, and out-of-home media (advertising placed on physical surfaces such as billboards, transit stops, and storefronts) (YouGov BrandIndex, Q2 2026)
- REI: 9.0% to 17.2%, following a spring sale discounting more than 6,000 products (YouGov BrandIndex, Q2 2026)
- Google Assistant: 8.1% to 15.8% (YouGov BrandIndex, Q2 2026)
A note on scope: ChatGPT and OpenAI are tracked as separate entries in BrandIndex, so their figures are not double-counted. The full ranking also included Stacy’s, Philips, Bridgestone, Dove Baby, and Bumble Bee, per Search Engine Journal’s reporting. The analysis covers U.S. Gen Z adults specifically, not all U.S. consumers.
What Actually Drove the AI Numbers?
Anthropic and OpenAI reached similar Consideration levels through different approaches, according to Search Engine Journal’s reporting. Anthropic ran its first Super Bowl spot with a single message: that Claude would remain free of advertising. During the quarter, it also shipped Claude Cowork, Claude Design, and new models, while loosening usage limits. OpenAI built its Super Bowl campaign around Codex and kept iterating on ChatGPT’s default model through the spring.
The non-AI brands on the list are a useful reference point. Johnnie Walker’s Consideration jump came from a paid media campaign. REI’s came from a promotional sale that earned coverage in lifestyle and outdoor press. None of it involved AI-search tactics. Search Engine Journal’s analysis is direct on this point: “It’s seasonal timing, promotional spend, and category demand doing what they’ve always done.”
Is Google Assistant’s Rise a Real Signal?
Google Assistant’s Consideration doubled from 8.1% to 15.8% during the same quarter Google was actively steering users away from Assistant and toward Gemini. That pivot followed Google I/O 2026 in May, where Google unveiled Gemini 3.5 Flash and launched its first new smart speaker in six years, as documented in Google’s official I/O 2026 blog. A brand gaining Consideration while its parent company is winding it down is not a strategy win. As Search Engine Journal noted, it is closer to residual name recognition catching a lift from adjacent news. That distinction matters before treating a Consideration chart as clean evidence of deliberate brand strategy.
Why the Trust Gap Is the More Actionable Number
A separate YouGov 19-market survey on search behavior, covered by Search Engine Journal the month prior to the Consideration ranking, found U.S. trust in AI assistants at 28%. That sits 42 percentage points below the trust consumers place in traditional search engines, and even further behind maps and navigation apps. Consideration and trust are not the same currency. Gen Z will apparently consider buying from Claude or OpenAI. A much smaller share of Americans overall are ready to trust either one to deliver a factual answer. They move on different timelines and respond to different inputs, as Search Engine Journal’s analysis concluded.
What This Means for AI-Search Visibility
Here is the simplest way to read this data gap: a brand can become famous faster than it becomes trusted. Think of a new restaurant that opens to a long line on day one because of strong press coverage. People know the name; some will try it. But reviews take time to accumulate, and reviews are what determine whether the recommendation spreads. In AI-search terms, Consideration is the line out front. Trust is what determines whether someone actually acts on what the AI tells them.
The following is Hingewise analysis, not a claim from either source. The Consideration surge for Claude and OpenAI reflects AI platform adoption momentum, not confirmation that AI citations are trusted at scale. Brands treating AI-search visibility as solved once their content starts appearing in AI answers are optimizing for a delivery channel where end-user trust sits at 28%. That is a meaningful ceiling on the downstream value of those mentions today.
One thing neither source states explicitly, but the comparison implies: Consideration and trust are likely to close their gap at different speeds by query category. Low-stakes queries (gift recommendations, casual how-tos) will probably see faster trust growth than high-stakes queries (health decisions, financial guidance, legal questions). Brands in high-stakes categories may find that citation frequency matters less than the credibility signals that make a citation feel safe to act on: named authors, verifiable data, and transparent methodology. These are, notably, the same signals YouGov’s own trust research identifies as the levers most likely to move that 28% figure upward.
Hingewise’s assessment: Consideration is the attention economy. Trust is the citation economy. The tactics that drove Consideration this quarter (Super Bowl campaigns, seasonal sales, lifestyle press placements) are largely separate from what builds citation credibility. Treating these as the same strategic objective is the most common misread visible in how brands are currently tracking AI-search performance.
Before You Adjust Your AI-Search Strategy Based on This Data
- Confirm whether your target audience is U.S. Gen Z adults specifically. YouGov’s Consideration ranking applies to that segment, not all users or all markets.
- Keep brand Consideration tracking separate from AI citation tracking. They respond to different inputs and move on different timelines.
- Identify the stakes level of your target query types. Trust gaps close at different rates depending on whether queries are low-stakes or high-stakes by nature.
- Audit your content for the signals YouGov’s trust research links to higher AI credibility: named sources, verifiable data, and transparent methodology.
- Do not read a Consideration lift for a brand being actively wound down (like Google Assistant amid the Gemini transition) as a signal of healthy brand momentum.
- Map your investment to the right goal. Paid media and promotional campaigns move Consideration. Source credibility and factual accuracy move citation trust. These are different inputs.
What to Watch
The Consideration scores for Claude and OpenAI are a single quarter’s snapshot from Q2 2026. Whether they translate into durable consumer trust, and how quickly, will be the more useful signal to track across the second half of the year. Michael Dimock, Pew Research’s president, has cautioned against over-indexing on generational cohort labels, and the same caution applies to a single quarter’s movement in a brand-tracking ranking. Google’s active transition from Assistant to Gemini will also likely produce anomalous Consideration readings for both products across several more quarters before the picture stabilizes.
