American Express AI Visibility Market Strategy Report - Certificates of Deposits

Answer Capsule

American Express holds the second-highest valid recommendation coverage in the October 2026 certificates of deposits benchmark at 24.84%, trailing category leader Capital One at 27.33% by 2.49 points. The brand pairs strong recommendation conversion with a declining raw mention presence rate of 44.72%, meaning it is recommended more often than it is mentioned. Its clearest win is a 10.56% top-three placement rate, second only to Capital One, while its clearest weakness is a rank-one rate of just 0.62%. The biggest opportunity sits in converting its already-efficient recommendation coverage into first-position placements across high-intent CD prompts.

Who This Report Is For

This report is for American Express marketing, brand, and deposit-product leaders who need to understand how AI systems recommend the brand in certificates of deposits discovery, where competitors are displacing it, and what the public evidence layer shows about why.

Report Card

Executive Summary

American Express holds the second position in the October 2026 certificates of deposits benchmark with 24.84% valid recommendation coverage, behind Capital One at 27.33%. The 2.49-point gap between the top two brands is narrow, but the underlying signals diverge sharply. American Express converts a raw mention presence rate of 44.72% into 24.84% recommendation coverage, a conversion ratio that exceeds Capital One's, which converts 77.64% presence into 27.33% coverage. The brand is being recommended efficiently relative to how often it appears.

The recommendation profile is positive. American Express recorded 41 positive mentions, 30 neutral mentions, and 1 negative mention across 72 mentions, producing a net sentiment score of 0.5556. That is the second-highest sentiment score among the leading brands, behind Bread Savings at 0.963. The brand made 40 valid recommendations and 17 top-three placements, giving it a 10.56% top-three rate, second only to Capital One at 13.66%.

The clearest weakness is first-position placement. American Express recorded a rank-one rate of just 0.62%, meaning it appeared as the single top recommendation in only 1 of 161 qualified observations. Capital One recorded 3 rank-one placements for a 1.86% rate, and Bread Savings recorded 9 for a 5.59% rate. American Express shows a 9.94-point gap between its top-three rate and its rank-one rate, the widest such gap among the leading cluster.

The strongest platform signal for American Express is Perplexity, where the brand recorded a 41.2% valid recommendation coverage rate and a 29.4% top-three rate. Google AI Mode also shows strength with a 40.0% valid recommendation coverage rate and a perfect 1.0 net sentiment score across 9 mentions. The weakest platform signal is ChatGPT, where American Express recorded a 23.5% valid recommendation coverage rate but zero top-three placements and an average recommended rank of 6.

The clearest platform gap is Gemini. American Express recorded a 12.8% valid recommendation coverage rate on Gemini, well below its overall average, with no rank-one placements and an average recommended rank of 2.4. The brand also shows no top-three placements on ChatGPT despite 4 valid recommendations there, suggesting those recommendations cluster in lower positions.

The benchmark also identified six high-severity factual inconsistencies involving American Express across three platforms: Copilot, Google AI Mode, and Google AI Overviews. These conflicts center on annual fee figures for the Amex Platinum Card, the Amex Gold Card, and the Delta SkyMiles Gold Card, plus a guest access policy conflict. The inconsistencies indicate that AI systems are synthesizing conflicting pricing information from the public source layer.

Note on taxonomy: the tracked entity list has alternated between common and formal brand names across the benchmark series. American Express appeared under its common name in July and October 2026 and under its formal name in August and September 2026. Month-over-month movement should be read with that naming change in mind.

What American Express Is Winning

Questions This Section Answers

• How does American Express convert raw mentions into valid recommendations compared with Capital One?
• Which platforms show the strongest recommendation and sentiment signals for American Express?

American Express holds the second-strongest recommendation position in the certificates of deposits category. Its 24.84% valid recommendation coverage rate places it ahead of eight tracked competitors and within 2.49 points of the category leader. The brand made 40 valid recommendations across 161 qualified observations, the second-highest count in the benchmark.

The brand's recommendation efficiency is notable. American Express converts a 44.72% raw mention presence rate into 24.84% valid recommendation coverage, a conversion ratio of approximately 56%. Capital One converts 77.64% presence into 27.33% coverage, a ratio of approximately 35%. This means American Express is more likely to be recommended when it appears than the category leader is.

Sentiment framing is a clear strength. American Express recorded a net sentiment score of 0.5556, reflecting 41 positive mentions against 1 negative mention. Only Bread Savings recorded a higher sentiment score at 0.963. The brand's positive visibility rate of 25.5% is the second-highest in the category, behind Capital One at 28.6%.

Where American Express Has the Clearest AI Visibility Gaps

Questions This Section Answers

• Why is American Express being shortlisted but not selected first in CD recommendation prompts?
• Where does American Express lose top-three placements on ChatGPT and Gemini?
• What does the decline in raw mention presence rate indicate about how concentrated its recommendations have become?

The clearest gap is first-position placement. American Express recorded a rank-one rate of 0.62%, meaning it appeared as the single top recommendation in only 1 of 161 qualified observations. Capital One recorded 3 rank-one placements for a 1.86% rate, and Bread Savings recorded 9 for a 5.59% rate. The 9.94-point gap between American Express's top-three rate of 10.56% and its rank-one rate of 0.62% is the widest among the three leading brands. The brand is being shortlisted but not selected first.

ChatGPT represents a platform-specific gap. American Express recorded 4 valid recommendations on ChatGPT but zero top-three placements and an average recommended rank of 6. The brand's valid recommendation coverage on ChatGPT is 23.5%, which is close to its overall average, but those recommendations are landing in lower positions. Capital One recorded a 35.3% valid recommendation coverage rate on ChatGPT with 2 top-three placements, and Bread Savings recorded a 35.3% coverage rate with 1 top-three placement and 1 rank-one placement.

Gemini shows a coverage gap. American Express recorded a 12.8% valid recommendation coverage rate on Gemini, roughly half its overall average. The brand recorded 5 valid recommendations on Gemini but zero top-three placements and zero rank-one placements. Capital One recorded a 20.5% coverage rate on Gemini with 8 top-three placements, and Bread Savings recorded a 23.1% coverage rate with 8 top-three placements and 7 rank-one placements.

The raw mention presence rate declined against the July 2026 baseline. American Express recorded a 44.72% presence rate in October 2026, down 11.9 points from 56.6% in July 2026. The brand is being mentioned less often overall while maintaining recommendation coverage, which suggests its recommendations are concentrated in a narrower set of prompts.

The brand's own domain does not appear in the top 10 cited domains for the certificates of deposits category. The top cited domains are nerdwallet.com, bankrate.com, cnbc.com, youtube.com, google.com, finance.yahoo.com, thepointsguy.com, wallethub.com, reddit.com, and forbes.com. Financial comparison and review sites dominate the citation layer, and no tracked brand's own domain appears in the top 10.

Biggest Opportunity

Questions This Section Answers

• What would it take for American Express to convert its top-three placements into rank-one recommendations?
• How does Bread Savings achieve a higher rank-one rate with a much smaller mention footprint?
• Why does the citation layer matter for moving American Express from a reference to a first-position recommendation?

The biggest opportunity for American Express is converting its top-three placements into rank-one placements. The brand recorded 17 top-three placements but only 1 rank-one placement in October 2026. Closing that gap would move American Express from a shortlist brand to a default recommendation in high-intent CD prompts.

Bread Savings shows what a narrower, more focused recommendation footprint can produce. It recorded a 5.59% rank-one rate despite a 16.8% presence rate, well below American Express's 44.72%. First-position placement does not require the widest mention footprint; it requires the strongest fit between the prompts where a brand is recommended and the way those recommendations are framed.

The path from reference to recommendation for American Express runs through the citation layer. The top cited domains in the category are financial comparison and review sites, and American Express does not appear among them. Building a stronger presence in the source pages that AI systems retrieve for CD recommendation prompts could help the brand move from a top-three mention to a first-position recommendation.

Competitive Landscape

Questions This Section Answers

• Where does American Express rank against Capital One and Bread Savings on top-three and rank-one placement?
• How does American Express's sentiment score compare with the other tracked CD brands?

Capital One holds the strongest recommendation-stage position in the certificates of deposits category, with American Express as the closest challenger. Bread Savings shows the highest rank-one rate despite lower overall coverage, and the remaining brands trail significantly on top-three placement.

Average recommended rank covers rank-eligible recommendations only.

American Express holds the second-highest top-three rate at 10.56% but ranks sixth on rank-one rate at 0.62%, behind Bread Savings, JPMorgan Chase & Co., Capital One, Morgan Stanley, and Wells Fargo & Co. The brand's average recommended rank of 3.45 is mid-pack, and its sentiment score of 0.5556 is the second-highest in the table.

Why This Matters

Questions This Section Answers

• What does American Express's gap between mention rate and recommendation rate mean for the CD decision moment?
• How do the pricing inconsistencies and citation gaps connect to the brand losing first-position recommendations?

AI presence alone is not enough. American Express is mentioned in 44.72% of qualified observations but recommended in only 24.84%, and it appears as the first recommendation in just 0.62%. The brand is being shortlisted but not selected first. In a category where buyers ask AI systems for the best CD rates and the top certificate of deposit accounts, a top-three mention that does not convert to a first-position recommendation means the brand is losing the decision moment to Capital One, Bread Savings, or another competitor.

The next move is targeted correction of the prompt, page, and citation layers. The six high-severity pricing inconsistencies show that AI systems are synthesizing conflicting information about American Express card products from the public source layer. Correcting those source conflicts and building a stronger presence in the comparison sites that AI systems cite for CD recommendations would help the brand move from a shortlist mention to a default recommendation.

Core Metrics

Sentiment Score

Sentiment Score = (positive mentions × 1 + neutral mentions × 0 + negative mentions × -1) / total mentions

For American Express in October 2026: (41 × 1 + 30 × 0 + 1 × -1) / 72 = 40 / 72 = 0.5556.

This score matters because unclassified mention counts are misleading. A brand with 72 mentions could look strong on a share-of-voice basis, but if most of those mentions are neutral references rather than positive recommendations, the brand is not actually winning the decision moment. American Express recorded 30 neutral mentions against 41 positive mentions, meaning 41.7% of its mentions were neutral references rather than positive recommendations.

Share of voice is a diagnostic metric, not a business KPI. A positive recommendation, a neutral reference, a cautionary mention, and a competitor-displaced mention are not equal. American Express's 0.5556 sentiment score reflects a mostly positive framing, but the 30 neutral mentions represent observations where the brand appeared without being recommended. Counting all 72 mentions as wins would overstate the brand's position.

Classified sentiment is required before interpreting AI visibility. The 1 negative mention and the 30 neutral mentions are not recommendation credit. Only the 40 valid recommendations count as recommendation-stage visibility. The sentiment score helps separate framing quality from recommendation coverage.

Sentiment by Platform

Methodology

1. This report is a benchmark-based analysis of American Express AI visibility in the certificates of deposits category for October 2026. It is not a client implementation case study.
2. The reporting window is October 2026, with comparisons to the July 2026 baseline where available.
3. Six AI platforms were tracked: ChatGPT, Copilot, Gemini, Perplexity, Google AI Mode, and Google AI Overviews.
4. The benchmark began with 800 prompt-surface observations, covering 602 unique questions. Of those, 182 were relevant to the certificates of deposits category and 161 qualified as benchmark observations.
5. Ten companies were tracked: American Express, Bank of America Corp., Bread Savings, Capital One, Citigroup Inc., Goldman Sachs Group, JPMorgan Chase & Co., Morgan Stanley, U.S. Bancorp, and Wells Fargo & Co.
6. One public high-intent cluster carried sufficient data: C01, Best CD Rates & Top Certificate of Deposit Accounts. Clusters C02 (CD Rate Comparisons) and C03 (CD Pricing, Rates & Return Evaluation) recorded no qualified observations in October 2026.
7. A mention is defined as any appearance of the brand in a qualified observation, regardless of whether the brand was recommended.
8. A valid recommendation is defined as an observation where the brand appears in a valid recommendation context, as marked by the benchmark dataset. Neutral, cautionary, and comparison-anchor mentions are not counted as valid recommendations.
9. Top-three rate is the share of qualified observations where the brand appears among the top three recommended options. Rank-one rate is the share where the brand is the single top recommendation.
10. Average recommended rank covers rank-eligible recommendations only. It is calculated from positive valid recommendations with rank 1 through 10.
11. The tracked entity list has alternated between common and formal brand names across the series. American Express appeared under its common name in July and October 2026 and under its formal name in August and September 2026. This affects how month-over-month movement is attributed.
12. The qualified denominator fell to 161 observations in October 2026 from 211 in September 2026, which changes the weight each observation carries in the percentages. Several movements, including U.S. Bancorp at 1.2% and Bank of America Corp. at 2.5%, come from small absolute counts of valid recommendations.
13. Source presence is evidence about the information environment, not proof that a source caused a recommendation. The benchmark retains citations where exposed but does not treat citation frequency as endorsement.
14. The public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone.
