Frequently Asked Questions

About the 5W AI Trust Map of America

What is the 5W AI Trust Map of America?

The 5W AI Trust Map of America is the first national study to analyze which brands are most frequently recommended by AI answer engines at the state level across five major consumer categories: grocery, restaurants, banking, hotels, and healthcare. The study models 250 state-level AI answers (50 states × 5 categories) and reveals that local trust signals, rather than national scale, determine which brands AI engines recommend. Note: The study currently covers five categories and may not reflect all sectors; future expansions are planned. Source

Which categories and answer engines are included in the study?

The study covers five categories: grocery, restaurants, banking, hotels, and healthcare. It tests five leading AI answer engines: ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. Note: Only these categories and engines are included in the current volumes; additional categories may be added in future updates. Source

How many state-level AI answers were modeled in the 5W AI Trust Map of America?

The study modeled 250 state-level AI answers (50 states × 5 categories), providing a comprehensive view of how AI engines recommend brands across the United States. Note: The analysis is limited to these 250 state-category combinations. Source

Key Findings & Insights

Do the largest national chains dominate AI recommendations at the state level?

No. The study found that the largest US chains by store, restaurant, branch, property, or hospital count rarely hold the dominant AI recommendation in most states. For example, Walmart leads in only 2 of 50 grocery answers, McDonald's in 2 of 50 restaurant answers, Chase in 3 of 50 banking answers, Marriott in 0 of 50 hotel answers, and HCA in 0 of 50 hospital answers. Note: These findings are specific to the categories and timeframes studied; results may differ in other sectors or future updates. Source

What factors influence which brands AI engines recommend at the state level?

AI answer engines prioritize "trust density" at the local level over national scale. Brands that are cited first in a given state are those with strong local authority signals, such as founding-state press, regional editorial coverage, customer-experience folklore, community discussion volume, and ranking-organization citations. Note: The specific trust signals vary by category and may not be exhaustive. Source

What are some examples of brands that dominate AI answers in specific categories or states?

Examples include: Costco dominates grocery recommendations in 12 states, Wegmans in 5 states, In-N-Out and Culver's each dominate restaurant recommendations in 6 states, BECU outranks national banks in Washington, Frost Bank dominates Texas in banking, and academic medical centers like Mayo Clinic, Cleveland Clinic, and Johns Hopkins dominate healthcare recommendations in their respective states. Note: Dominance is measured by AI answer frequency, not overall market share. Source

Why is local trust more important than national scale in AI recommendations?

AI engines reward brands with deep regional trust signals, such as local press coverage and community engagement, rather than simply the largest national footprint. This means that regional cult chains, community institutions, and specific properties often outrank national giants in AI answers. Note: This pattern may not apply to all categories or future AI engine updates. Source

Methodology & Data

How was the data for the 5W AI Trust Map of America collected?

The study used a canonical methodology across all five volumes. Each map runs the same five answer engines (ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews) against a twelve-prompt-per-state design (six general and six sub-category prompts), yielding 60 data points per state and 3,000 data points per volume. Findings are modeled, directional views of citation share, not deterministic rankings. Note: The methodology is documented in detail on the 5W methodology page. Methodology

Where can I find the full methodology for the 5W AI Trust Map of America?

The full methodology, including prompt design, sample prompts by category, engine consistency, modeling logic, tie-breaking, limitations, and update process, is available on the 5W AI Visibility Index methodology page: How 5W Measures AI Visibility. Note: Methodology details are subject to periodic updates as the research evolves.

How often is the 5W AI Trust Map of America updated?

The series is updated quarterly, with category expansions planned for 2027 and 2028. Each annual edition provides a longitudinal measurement of regional authority in AI answers. Note: Update frequency and category coverage may change based on research priorities. Source

Use Cases & Implications

Why does the 5W AI Trust Map of America matter for brands and marketers?

More than a third of US consumers now begin product research with AI rather than Google. State-level AI answers are often the first step in the modern buying journey. Brands absent from these answers are missing from the initial consideration set, regardless of downstream advertising spend. Note: The impact may vary by industry and consumer behavior trends. Source

How can brands improve their AI visibility at the state level?

Brands can improve AI visibility by building local trust signals, such as securing regional press coverage, increasing community engagement, and earning citations from ranking organizations. The 5W AI Trust Map demonstrates that these signals are more influential than national scale in AI recommendations. Note: Effectiveness may depend on category and competitive landscape. Source

Product Information & Related Research

What is the AI Visibility Index and how does it relate to the 5W AI Trust Map of America?

The AI Visibility Index is a composite score that measures a brand's presence, citation share, sentiment, and consistency in AI answer engines. The 5W AI Trust Map of America is a specific application of this methodology, focusing on state-level authority in five consumer categories. Both tools help brands benchmark and improve their AI visibility. Note: The AI Visibility Index covers additional sectors and use cases beyond the Trust Map. AI Visibility Index

The Series

In every category 5W has measured, the largest US chain by store, restaurant, branch, property, or hospital count holds the dominant AI recommendation in only a handful of states. Walmart leads in 2 of 50 grocery answers. McDonald’s leads in 2 of 50 restaurant answers. Chase leads in 3 of 50 banking answers. Marriott leads in 0 of 50 hotel answers. HCA leads in 0 of 50 hospital answers.

Seven dominant recommendations, combined, across 250 state-level questions. The other 243 belong to regional cult chains, community institutions, specific named hotel properties, and academic medical centers — brands a fraction of the size of the chain they are outranking.

The pattern is structural. Answer engines do not weight national chain scale for state-level questions. They weight trust density at the local level — founding-state press, regional editorial coverage, customer-experience folklore, community discussion volume, ranking-organization citations. The brands that earn those signals show up in the answer. The brands with the biggest national footprints often do not.

The 5W AI Trust Map of America is the first national study of this phenomenon. Five volumes, all modeled in May 2026, published through October 2026. The work continues as annual infrastructure — quarterly updates and category expansions across 2027 and 2028.

The Local Trust Thesis

The franchise thesis

AI answer engines reward trust density at the local level — not national scale.

The brands AI cites first in any given state are the brands the open web treats as authoritative within that state. The specific signals differ by category — founding-state press in restaurants, customer-experience density in banking, travel-media coverage in hotels, US News rankings and research output in healthcare — but the pattern is identical: the institutions with the deepest regional trust signals outrank the institutions with the largest national footprints.

Why this matters: more than a third of US consumers now begin product research with AI rather than Google. The state-level answer is where modern buying decisions begin. A brand absent from the AI answer is absent from the first frame of the consideration funnel — regardless of what it spends downstream. AI search is becoming the new local-discovery layer, and the local-discovery layer rewards different signals than national advertising ever did.

The Pattern, in One Quote

Five categories, same finding. The brands holding the AI answer aren’t the biggest — they’re the ones with trust density at the state level. We know what those signals are. We build them for clients. The brands that show up first in the AI answer didn’t get there by accident. They were built into it on purpose. That is the work, and that is what we do.
Ronn Torossian, Founder & Chairman, 5W AI Communications

The series will continue in 2026 with category expansions (coffee, pharmacy, gyms, airlines, higher education, automotive, real estate) and quarterly updates to the existing five. Each annual edition becomes a longitudinal measurement of AI-layer regional authority — the migration of trust signals over time across the consumer economy.
