American Express AI Market Strategy Report - Certificates of Deposits

Answer Capsule

American Express Co. holds minimal recommendation-stage visibility in AI-driven certificate of deposit discovery, with valid recommendation coverage of just 1.42% in September 2026. The brand appears in only 10.90% of qualified observations, and none of those appearances convert into top-three or rank-one recommendations. The clearest weakness is a near-total absence from the recommendation layer, while the clearest opportunity lies in converting its small base of positive mentions into rank-eligible recommendations across platforms where it already registers presence.

Who This Report Is For

This report is for deposit product leaders, brand strategy teams, and digital acquisition executives at American Express who need to understand how AI systems currently frame the brand in certificate of deposit discovery conversations.

Report Card

Executive Summary

American Express Co. holds a marginal position in AI-generated certificate of deposit recommendations. The September 2026 LLM Authority Index benchmark shows the company appearing in 23 of 211 qualified observations, a raw mention presence rate of 10.90%. Of those appearances, only 3 register as valid recommendations, producing coverage of 1.42%. The company records no top-three placements and no rank-one recommendations.

The sentiment picture is modestly positive. American Express Co. received 5 positive mentions and 18 neutral mentions, with zero negative framing, producing a net sentiment score of 0.2174. This indicates that when AI systems do reference the brand, the framing is constructive, but those references rarely rise to the level of an actual recommendation.

The strongest platform signal comes from Perplexity, where the company recorded its only rank-eligible recommendation with an average recommended rank of 4. The clearest platform gap is across the Google surfaces, where American Express Co. appears in AI Mode and AI Overviews but never converts presence into recommendation credit.

The benchmark data also reflects a tracking transition. American Express was tracked under its shortened name in July 2026 and shifted to American Express Co. in August 2026. The apparent coverage decline from 37.0% to 0.0% for the July-only label is an attribution shift tied to that naming change, not necessarily a loss of underlying market presence.

What American Express Is Winning

Questions This Section Answers

• Where does American Express Co. currently show measurable strength in CD-related AI responses?
• Which platform is most likely to give American Express Co. recommendation credit?

American Express Co. has few measurable wins in this dataset, and they are narrow.

The brand records zero negative mentions across all 211 qualified observations. Every reference to American Express Co. in AI-generated responses is either positive or neutral, which is a cleaner framing profile than several competitors that carry negative sentiment in this category.

The company also holds a positive net sentiment score of 0.2174. While the sample is small, the absence of negative framing means the public evidence layer does not currently contain cautionary or critical narratives that AI systems are surfacing.

Perplexity is the one platform where American Express Co. converts presence into recommendation credit. The brand recorded 1 valid recommendation on that surface with an average recommended rank of 4, suggesting that at least one high-intent prompt cluster produces a rank-eligible mention.

Where American Express Has the Clearest AI Visibility Gaps

Questions This Section Answers

• Why does American Express Co. trail category leaders like Morgan Stanley and Bread Savings?
• On which AI surfaces does the brand appear without earning any recommendation credit?

The dominant gap is recommendation conversion. American Express Co. appears in 23 observations but is recommended in only 3, a conversion rate that leaves the brand far behind the category leaders. Morgan Stanley converts 158 mentions into 69 valid recommendations, while Bread Savings converts 81 mentions into 63 valid recommendations. American Express Co. is present but not chosen.

The brand holds no top-three placements and no rank-one recommendations in September 2026. By comparison, Morgan Stanley records a 21.33% top-three rate and a 10.43% rank-one rate, while Bread Savings records 17.06% and 4.27% respectively. Even JPMorgan Chase & Co., with lower overall coverage, achieves a 7.58% top-three rate and a 4.74% rank-one rate.

Platform coverage is uneven. American Express Co. appears on all six tracked surfaces but holds valid recommendation coverage on only two: Gemini at 3.77% and Perplexity at 3.33%. On ChatGPT, Copilot, AI Mode, and AI Overviews, the brand registers presence but earns zero recommendation credit. The Google surfaces are the clearest gap, with AI Mode showing 1 mention and AI Overviews showing 5 mentions, none of which convert into recommendations.

Biggest Opportunity

Questions This Section Answers

• What is the clearest path for American Express Co. to turn mentions into CD recommendations?

The clearest opportunity for American Express Co. is converting its existing positive mention base into rank-eligible recommendations on the platforms where it already has presence. The brand currently holds 23 mentions with zero negative framing, yet only 3 of those mentions become valid recommendations. The gap between positive framing and recommendation conversion suggests the issue is not how AI systems describe the brand, but whether the public evidence layer supports recommending it in certificate of deposit discovery prompts.

Perplexity is the proof point. It is the only platform where American Express Co. earns recommendation credit, which means at least one prompt context produces a rank-eligible outcome. Expanding the source footprint that supports CD-specific recommendations, particularly around rate competitiveness and product attributes, would give AI systems more retrievable material when forming shortlists.

Competitive Landscape

Questions This Section Answers

• Where does American Express Co. rank against the 10 tracked CD competitors?
• Which competitors hold the strongest top-three and rank-one recommendation rates?

Morgan Stanley and Bread Savings hold dominant recommendation-stage strength in this category, with American Express Co. positioned at the bottom of the tracked competitive set. The brand trails every tracked competitor in valid recommendation coverage.

Average recommended rank covers rank-eligible recommendations only.

American Express Co. sits at the bottom of the competitive table by top-three rate and rank-one rate. Its single rank-eligible recommendation places it at rank 4, which is mid-pack for average recommended rank, but the sample is too small to treat as a stable signal. The brand's sentiment score of 0.2174 is higher than several competitors with stronger recommendation positions, which reinforces that framing quality is not the constraint.

Why This Matters

Questions This Section Answers

• Why does the gap between positive framing and recommendation conversion matter for American Express Co.?

AI-generated responses are becoming the first filter in certificate of deposit discovery. When a buyer asks which institutions offer competitive CD rates, the brands that appear in the recommendation layer shape the consideration set before the buyer ever visits a website. American Express Co. is currently present in that conversation but rarely chosen, which means the brand is visible without being actionable.

The gap between positive framing and recommendation conversion is the strategic issue. AI systems do not describe American Express Co. negatively, but they also do not shortlist it. Closing that gap requires targeted work on the prompt, page, and citation layers so the public evidence supports recommendation outcomes, not just neutral references.

Core Metrics

Sentiment Score

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

For American Express Co., the calculation is (5 × 1 + 18 × 0 + 0 × -1) / 23, producing a net sentiment score of 0.2174.

This score matters because unclassified mention counts are misleading. A brand can appear frequently in AI responses while being framed negatively or neutrally, and neither outcome supports recommendation conversion. Share of voice is a diagnostic metric, not a business KPI. A positive recommendation, neutral reference, cautionary mention, and competitor-displaced mention are not equal, and counting all mentions as wins is bad measurement. Classified sentiment is required before interpreting AI visibility, because the framing quality determines whether presence can convert into buyer action.

Sentiment by Platform

Methodology

1. This report is a company-level AI market strategy readout based on the LLM Authority Index AI Market Discovery Index for the Certificates of Deposits vertical, not a client implementation case study.
2. The reporting window is September 2026, with July and August 2026 referenced for movement context.
3. Six AI/search surface families were tracked: ChatGPT, Copilot, Gemini, Perplexity, AI Mode, and AI Overviews.
4. The benchmark collected 800 prompt-surface observations in September 2026, of which 658 were unique questions and 251 were relevant to the certificates of deposits vertical.
5. Brand-level percentages use 211 qualified observations as the public denominator.
6. The competitor universe includes 10 tracked brands: Bread Savings, American Express Co., Bank of America Corp., Capital One Financial Corp., Citigroup Inc., Goldman Sachs Group, JPMorgan Chase & Co., Morgan Stanley, U.S. Bancorp, and Wells Fargo & Co.
7. The public benchmark captured qualified observations in one buyer-intent cluster: Brand Recommendation. No qualified observations were recorded in Pricing & Value or Multi-Brand Comparison clusters.
8. Stage 0 extraction retains the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and where exposed, citations or attributable evidence sources.
9. A mention is any qualified observation where the brand appears in any form, regardless of framing or recommendation outcome.
10. A valid recommendation is a qualified observation where the brand appears in a recommendation context with rank eligibility.
11. The July-to-September series includes a brand re-identification event in August 2026, where American Express was replaced by American Express Co. as the tracked entity. The apparent coverage decline for the July-only label is an attribution shift, not necessarily a loss of market presence.
12. Limitations: The qualified denominator is smaller than the raw collection universe, several movements come from small absolute counts, and the public benchmark does not measure market share, attributable sales, or causality from metric movement alone.
