Report Card

Executive Summary

American Express holds 39.53% valid recommendation coverage in the September 2026 Savings Account benchmark, ranking seventh among ten tracked brands. The brand appears in 44.97% of qualified AI answers, meaning it is mentioned in nearly half of all savings account recommendation queries, but it converts that presence into a valid recommendation shortlist position only 39.53% of the time. This 5.44-point gap between presence and recommendation coverage signals that American Express is visible in AI answers but is not consistently named as a recommended option.

The brand's recommendation coverage declined 4.9 points from 44.4% in August 2026 to 39.53% in September 2026. This movement was not flagged as a significant decline in the benchmark classification, but it represents a meaningful drop in recommendation-stage visibility. American Express also saw its top-three recommendation rate fall from 10.7% to 6.98%, and its rank-one rate remained low at 1.12%, indicating that when the brand does appear in recommendations, it rarely occupies the first position.

The strongest platform signal for American Express is Google AI Overviews, where the brand achieved 46.5% valid recommendation coverage and a 3.2% rank-one rate. The brand's presence on AI Overviews reached 50.3%, suggesting that Google's AI-generated summaries surface American Express more consistently than other platforms. However, even on this strongest platform, the brand trails category leaders by substantial margins.

The weakest platform signals appear on Perplexity and Copilot. On Perplexity, American Express achieved only 17.4% valid recommendation coverage despite 30.2% presence, and on Copilot, the brand reached 49.4% coverage but with a rank-one rate of just 1.2%. These patterns suggest that American Express is being mentioned as context or comparison anchor rather than as a primary recommendation on these platforms.

The brand's net sentiment score of 0.9565 is among the highest in the category, indicating that when American Express is mentioned, the framing is overwhelmingly positive or neutral. This sentiment strength is not translating into recommendation conversion, which points to a gap in how the brand's value proposition is being surfaced and weighted in AI-generated shortlists.

The clearest competitive gap is with SoFi, which leads the category with 76.4% valid recommendation coverage. American Express trails SoFi by 36.9 percentage points in recommendation coverage and by 19.6 percentage points in rank-one rate. The brand also trails mid-tier competitors including Axos Bank (57.8%), Marcus by Goldman Sachs (48.2%), and CIT Bank (47.2%), all of which have lower presence rates but higher recommendation conversion.

What American Express Is Winning

Questions This Section Answers

• Where does American Express's AI framing and sentiment strength rank among savings account competitors?
• Which AI platform gives American Express its strongest recommendation coverage and rank-one rate?

American Express demonstrates strength in sentiment and framing quality. The brand's net sentiment score of 0.9565 ranks third among all tracked brands, behind only Axos Bank (0.9733) and Marcus by Goldman Sachs (0.9425, which is lower), placing American Express among the top three for framing quality. This indicates that when AI systems mention American Express in savings account contexts, the framing is consistently positive or neutral, with only one negative mention recorded across 716 observations.

The brand's strongest platform by recommendation coverage is Google AI Overviews, where American Express achieved 46.5% valid recommendation coverage. This platform also produced the brand's highest rank-one rate at 3.2%, suggesting that Google's AI-generated overviews are more likely to position American Express as a primary recommendation than other platforms.

American Express also shows a meaningful presence on Google AI Mode, where it achieved 44.4% valid recommendation coverage and 44.9% presence. This platform represents a significant surface for AI-generated recommendations, and the brand's performance here is stronger than its overall category position would suggest.

The brand's positive visibility rate of 43.2% indicates that American Express is framed positively in a substantial share of the observations where it appears. This sentiment strength provides a foundation for improving recommendation conversion, as the brand is not facing significant negative framing that would need to be corrected.

Where American Express Has the Clearest AI Visibility Gaps

Questions This Section Answers

• Where does American Express appear in AI answers but fail to convert into savings account recommendations?
• Which competitors with lower AI presence than American Express still earn higher recommendation coverage?

American Express shows its most significant recommendation gap on Perplexity, where the brand achieved only 17.4% valid recommendation coverage despite appearing in 30.2% of qualified observations. This 12.8-point gap between presence and recommendation coverage is the largest among all platforms for American Express, indicating that Perplexity surfaces the brand as context or comparison anchor rather than as a recommended option.

On Copilot, American Express achieved 49.4% valid recommendation coverage, which appears strong relative to the brand's overall performance. However, the rank-one rate on Copilot is just 1.2%, and the top-three rate is 2.4%. This pattern suggests that while Copilot mentions American Express frequently, it rarely positions the brand as a top recommendation. The brand's average recommended rank on Copilot is 6.1, the lowest among all platforms, indicating that when American Express does appear in Copilot recommendations, it typically appears near the bottom of the list.

The brand's performance on ChatGPT shows a similar pattern. American Express achieved 28.7% valid recommendation coverage on ChatGPT with a rank-one rate of 0.0%. The brand appears in 35.6% of ChatGPT observations but is never positioned as the first recommendation. This suggests that ChatGPT acknowledges American Express as a relevant option but consistently favors other brands when making primary recommendations.

Compared to category leader SoFi, American Express trails by 36.9 percentage points in valid recommendation coverage and 19.6 percentage points in rank-one rate. The gap is even more pronounced when comparing top-three rates: SoFi achieves 40.36% while American Express reaches only 6.98%. This indicates that American Express is not competing for the same recommendation positions as the category leader.

The brand also trails mid-tier competitors with lower presence rates. Axos Bank, which has a presence rate of 62.8% compared to American Express's 44.97%, achieves 57.8% valid recommendation coverage and a 5.87% rank-one rate. CIT Bank, with 53.1% presence, achieves 47.2% coverage and 5.59% rank-one rate. These competitors demonstrate that lower presence can still yield higher recommendation conversion when the brand's value proposition is effectively surfaced in AI-generated shortlists.

Biggest Opportunity

Questions This Section Answers

• Which AI platforms should American Express prioritize to close its presence-to-recommendation gap?
• What evidence layer changes would help convert American Express mentions into top-three savings account recommendations?

The clearest opportunity for American Express is to close the gap between raw mention presence and valid recommendation conversion, particularly on platforms where the brand is mentioned frequently but rarely recommended. The brand's 44.97% presence rate provides substantial visibility, but the 39.53% recommendation coverage indicates that AI systems are not consistently translating that visibility into shortlist positions.

The highest-priority target is Copilot, where American Express achieves 49.4% coverage but only 1.2% rank-one rate and an average recommended rank of 6.1. Improving the brand's positioning on Copilot from a bottom-of-list mention to a top-three recommendation would require strengthening the evidence layer that AI systems use to evaluate savings account options. This includes ensuring that American Express's savings account features, rates, and value propositions are clearly articulated in sources that Copilot retrieves and synthesizes.

The second priority is Perplexity, where the 12.8-point gap between presence and recommendation coverage suggests that the brand is being used as a comparison anchor rather than a recommended option. Addressing this gap would require building citation architecture that positions American Express as a primary recommendation in savings account contexts, not just a reference point.

Why This Matters

AI presence alone is not enough to win buyer shortlists. American Express appears in 44.97% of savings account AI answers, but converts that presence into a valid recommendation only 39.53% of the time. This gap means that in a substantial share of high-intent queries, the brand is visible but not chosen.

The next move is targeted correction of the prompt, page, and citation layers that shape AI-generated recommendations. By focusing on platforms where the presence-to-recommendation gap is largest and strengthening the evidence layer that AI systems use to evaluate savings account options, American Express can improve its position in AI-generated shortlists and capture more recommendation-stage visibility.

Core Metrics

Sentiment Score

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

For American Express in September 2026: (309 × 1 + 12 × 0 + 1 × -1) / 322 = 308 / 322 = 0.9565

This score indicates that American Express receives overwhelmingly positive or neutral framing when mentioned in AI-generated savings account recommendations. Only one negative mention was recorded across 716 qualified observations.

Sentiment score matters because unclassified mention counts are misleading. A brand can appear frequently in AI answers but receive cautionary or comparison-anchor framing that does not translate into recommendation credit. 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 in commercial value.

Counting all mentions as wins is bad measurement. American Express's high sentiment score indicates that the brand is not facing significant negative framing, which is a strength. However, the gap between sentiment strength and recommendation conversion suggests that positive framing alone is not sufficient to drive shortlist positioning. Classified sentiment is required before interpreting AI visibility, and American Express's sentiment profile suggests that the opportunity lies in converting positive mentions into active recommendations.

Methodology

1. This report analyzes American Express's AI recommendation performance in the Savings Account category for September 2026, using data from the LLM Authority Index AI Market Discovery benchmark.
2. The reporting window covers September 2026, with comparisons to August 2026 baseline data where available.
3. Six AI platforms were tracked: ChatGPT, Copilot, Gemini, Perplexity, Google AI Overviews, and Google AI Mode.
4. The analysis is based on 716 qualified observations from an initial collection of 800 prompt-surface observations.
5. The competitor universe includes ten tracked brands: SoFi, Capital One, Ally Bank, Axos Bank, Marcus by Goldman Sachs, CIT Bank, American Express, EverBank, Synchrony Bank, and Barclays.
6. One public high-intent cluster was active in September 2026: Best High Yield Savings Accounts (C01). The benchmark's defined universe for this vertical currently captures explicit recommendation requests rather than pricing or comparison queries.
7. Stage 0 extraction retained the query, AI surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources.
8. A mention is defined as any appearance of American Express in an AI-generated response to a qualified savings account prompt.
9. A valid recommendation is defined as an observation where American Express appears in a valid recommendation shortlist, as marked by the benchmark's classification system.
10. Ranking interpretation follows the benchmark's rank-eligibility rules: positive valid recommendations with rank 1-10 receive recommendation credit according to rank weights.
11. Limitations: 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. It records the change; it does not, by itself, establish why the change occurred.
12. Small counts matter. American Express's rank-one count of 8 recommendations represents a small base of observations. Percentage movements based on small counts should be interpreted with caution.
