Who This Report Is For

This report is for marketing, growth, and digital strategy leaders at Marcus by Goldman Sachs who need to understand how AI systems are currently recommending the bank in money market account discovery conversations.

Report Card

Executive Summary

Marcus by Goldman Sachs is visible but under-recommended relative to its presence. The bank appeared in 62.1% of qualified observations in September 2026, yet converted that presence into valid recommendations in only 52.0% of observations. That gap between presence and recommendation coverage indicates the bank is being mentioned in money market account conversations without being consistently put forward as a recommended option.

The benchmark shows a two-month decline across every layer of the recommendation funnel. Valid recommendation coverage fell from 62.4% in July 2026 to 52.0% in September 2026, a drop of 10.4 points. Presence fell from 72.3% to 62.1%, and the top-three rate fell from 28.9% to 18.7%. The rank-one rate dropped from 7.7% to 3.8%, meaning the bank is now winning the single top recommendation slot at less than half the July rate.

Sentiment framing remains positive. Marcus by Goldman Sachs recorded 389 positive mentions, 35 neutral mentions, and 1 negative mention in September 2026, producing a net sentiment score of 0.9129. The issue is not how the bank is framed when mentioned, but how often it is recommended and how prominently it is placed.

The strongest platform signal comes from ChatGPT, where Marcus by Goldman Sachs holds 73.3% valid recommendation coverage and a 37.8% top-three rate. The clearest platform gap is on Gemini, where coverage falls to 41.9% and the top-three rate drops to 17.2%. The weakest cluster is the only qualified cluster in this dataset, Best High-Yield Savings Accounts, where the bank's recommendation behavior is declining across all tracked metrics.

What Marcus by Goldman Sachs Is Winning

Marcus by Goldman Sachs holds a genuine recommendation pocket on ChatGPT. The bank reaches 73.3% valid recommendation coverage on that platform, with a 37.8% top-three rate and a 77.8% raw mention presence rate. This is the strongest platform performance in the bank's September 2026 profile and indicates that ChatGPT responses continue to surface and recommend the bank at meaningful rates.

The bank also maintains a strong positive framing profile. With 389 positive mentions against 1 negative mention, the net sentiment score of 0.9129 shows that when AI systems reference Marcus by Goldman Sachs, the framing is overwhelmingly favorable. There is no evidence of negative narrative formation around the brand in this dataset.

The bank retains a meaningful presence in the category overall. A 62.1% raw mention presence rate means Marcus by Goldman Sachs is still surfaced in more than six in ten qualified money market account conversations, keeping the brand inside the consideration set even as recommendation placement weakens.

Where Marcus by Goldman Sachs Has the Clearest AI Visibility Gaps

Questions This Section Answers

• How large is the gap between Marcus by Goldman Sachs's presence and its valid recommendation coverage?
• Where does Marcus by Goldman Sachs lose the most ground on top-three and rank-one placement?

The clearest gap is the conversion of presence into recommendation. Marcus by Goldman Sachs is mentioned in 62.1% of observations but recommended in only 52.0%, a 10.1-point gap. Several competitors convert presence into recommendation more efficiently. Ally Bank reaches 70.6% coverage from 81.9% presence, and Capital One reaches 62.9% coverage from 71.5% presence.

The top-three placement gap is more pronounced. Marcus by Goldman Sachs holds an 18.7% top-three rate, while Ally Bank holds 38.5% and Capital One holds 29.5%. The bank is being recommended, but it is appearing lower in shortlists. The average recommended rank of 3.66 confirms that when Marcus by Goldman Sachs is recommended, it tends to sit outside the top-three positions.

The rank-one gap is the sharpest competitive disadvantage. Marcus by Goldman Sachs wins the first recommendation position in only 3.8% of observations, while Ally Bank wins it in 17.8%. Capital One, which entered the tracked set this month, already holds a 6.6% rank-one rate. The bank that previously led this category in August 2026 is now being displaced at the moment of first choice.

Platform-level gaps reinforce the pattern. On Gemini, Marcus by Goldman Sachs holds 41.9% valid recommendation coverage and a 17.2% top-three rate, well below its ChatGPT performance. On Google AI Mode, the top-three rate falls to 7.3%, and on Google AI Overviews it reaches 15.2%. The bank's recommendation strength is concentrated on ChatGPT and does not carry evenly across the other AI surfaces.

Biggest Opportunity

Questions This Section Answers

• Which platforms offer Marcus by Goldman Sachs the clearest opportunity to improve top-three recommendation placement?

The clearest opportunity for Marcus by Goldman Sachs is reversing the decline in top-three recommendation placement on non-ChatGPT platforms. The bank already holds strong presence on Google AI Mode at 63.7% and Google AI Overviews at 46.1%, but converts that presence into top-three recommendations at only 7.3% and 15.2% respectively. These platforms are surfacing the bank without positioning it as a leading option.

Closing the gap between presence and top-three placement on Google AI Mode and Google AI Overviews would move the bank toward the recommendation behavior it already achieves on ChatGPT, where the top-three rate reaches 37.8%. The evidence suggests the bank's owned answer layer and supporting source footprint are strong enough to earn mention across surfaces, but the framing and citation architecture are not converting that visibility into shortlist placement outside ChatGPT.

Why This Matters

AI-generated recommendations are shaping which money market account providers reach the buyer shortlist. Marcus by Goldman Sachs is still present in most conversations, but presence alone is not enough when competitors are being placed higher and recommended first more often. The bank that led this category in August 2026 is now being displaced at the decision moment.

The next move is targeted correction of the prompt, page, and citation layers. Marcus by Goldman Sachs needs to convert its existing visibility into stronger recommendation placement, particularly on platforms where the bank is mentioned but not shortlisted. Without that correction, the bank risks being present in the conversation but absent from the choice.

Core Metrics

Sentiment Score

Questions This Section Answers

• How is the net sentiment score calculated for Marcus by Goldman Sachs?
• Why is classified sentiment required before interpreting AI visibility?

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

For Marcus by Goldman Sachs, the calculation is (389 × 1 + 35 × 0 + 1 × -1) / 425, producing a net sentiment score of 0.9129.

This score matters because unclassified mention counts are misleading. A brand can appear frequently in AI responses while being framed negatively or mentioned only as a comparison anchor. 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. Counting all mentions as wins is bad measurement. Classified sentiment is required before interpreting AI visibility, because the same presence rate can hide very different recommendation outcomes.

Sentiment by Platform

Methodology

1. This report is a benchmark-based analysis of Marcus by Goldman Sachs in the money market accounts category, produced from the LLM Authority Index AI Market Discovery Index and supporting metrics aggregation. It is not a client implementation case study.
2. The reporting window is September 2026, with July 2026 and August 2026 referenced for movement analysis.
3. Six canonical AI surface families were tracked: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode.
4. The benchmark began with 800 source prompt-surface observations and produced 684 qualified observations in September 2026 after relevance and qualification stages.
5. The competitor universe includes 10 tracked brands: Ally Bank, Capital One, CIT Bank, Discover Home Loans, Marcus by Goldman Sachs, Quontic Bank, Sallie Mae, Synchrony Bank, UFB Direct-Parent Company(Axos Financial, Inc.), and Vio Bank-(MidFirst Bank).
6. All 684 qualified observations fell into the Best High-Yield Savings Accounts cluster, representing the Brand Recommendation buyer-intent class. No qualified observations were recorded for Pricing & Value or Multi-Brand Comparison clusters.
7. Stage 0 extraction captured prompt-level observations including query, AI surface, answer, brand outcome, recommendation placement, sentiment, and citations where exposed.
8. A mention is defined as any qualified observation in which the brand appears, regardless of whether it is recommended.
9. A valid recommendation is defined as a clear, attributable recommendation of the brand within a qualified observation. Neutral references, cautionary mentions, and comparison-anchor appearances are not counted as valid recommendations.
10. The September 2026 tracking set introduced entity label changes for several brands, including the replacement of Capital One Auto Finance, CIT Bank (Acquiring Company: First Citizens BancShares, Inc), Sallie Mae Bank, and Synchrony with broader entity names. Marcus by Goldman Sachs was not affected by these label changes.
11. Limitations: The public benchmark cannot establish why any movement occurred. The qualified denominator of 684 is smaller than the raw collection of 800. The dataset contains no qualified observations for pricing, value, or head-to-head comparison prompts. Source presence is evidence about the information environment, not proof of causation.
12. Monetary benchmark metrics, including modeled AI Authority Value and related valuation figures, are excluded from this report by design.
