UK Digital Banking AI Visibility
Q2–Q3 2026 Comparison
How AI Share of Voice shifted for Monzo, Revolut, Starling and UK banking brands between April and August 2026 — measuring what changed, what drove it, and what comes next.
Executive Summary
Between Q2 (April 2026) and Q3 (August 2026), the UK digital banking AI visibility landscape moved in two simultaneous directions. Monzo weakened. Revolut strengthened. And the structural advantage Monzo enjoyed just four months ago has been cut nearly in half.
The comparison covers 198 consumer-intent queries run through ChatGPT, Gemini and Claude in two separate periods — capturing how AI assistants' responses to UK banking queries have evolved as both the AI models and the content landscape have changed.
Data note: All Claude data in this comparison uses the successful August 2026 rerun (70% completion rate across 66 queries). An initial Claude run showed a high timeout rate; the rerun supersedes those results. Claude visibility for Monzo improved from 1.5% in April to 10.6% in August — making it the platform with the largest percentage gain. Claude figures should be treated as directional rather than absolute.
- Revolut second at 11.2% (gap: 9.2pp)
- Gemini: 33.3% mention rate
- Claude: 1.5% mention rate
- Comparison queries: 57% visibility
- Informational: 5.1%
- Sentiment: 5.6/10 (mild positive)
- Revolut second at 11.7% (gap: 5.1pp)
- Gemini: 25.8% mention rate (-7.5pp)
- Claude: 10.6% mention rate (+9.1pp, directional)
- Comparison queries: 37.8% visibility
- Informational: 2.6%
- Sentiment: 5.0/10 (neutral)
Quarter-on-Quarter Rankings — All Six Banks
Revolut is the only UK digital bank to gain Share of Voice across the quarter. Every other bank declined, with NatWest showing the largest proportional drop.
| Bank | Q2 SoV (Apr) | Q3 SoV (Aug) | Change | Direction | Q2 Mention | Q3 Mention |
|---|---|---|---|---|---|---|
| Monzo Leader | 17.7% | 15.5% | −2.2pp | ▼ Declining | 19.2% | 16.7% |
| Revolut Gaining | 11.2% | 11.7% | +0.5pp | ▲ Gaining | 13.1% | 13.6% |

Key Findings — What Changed and Why
Monzo's leadership is eroding. -2.2pp in a single quarter, while Revolut gained +0.5pp. The gap has compressed from 9.2pp to 5.1pp. At constant velocity, Revolut overtakes Monzo within 3–6 months. This is not a data fluctuation — it reflects genuine competitive movement in AI training data and citation patterns.
Claude showed significant improvement as a visibility channel for Monzo. Monzo: 1.5% → 10.6% (+9.1pp) — the largest percentage gain across any platform and any brand in the Q2–Q3 comparison. However, Claude's primary recommendation rate (4.5%) remains well below ChatGPT (18.2%) and Gemini (19.7%). Note: August Claude data is directional (66-query rerun, 70% completion rate). The initial zero reading was likely a data artefact from query timeouts.
Gemini's weighting of financial content has changed. Monzo's Gemini mention rate dropped from 33.3% to 25.8% — the largest single metric movement across the comparison. This 7.5pp decline suggests either algorithm changes in how Gemini sources banking information, or intensified competition from content published by Revolut and Barclays on Gemini-indexed pages.
ChatGPT is the one bright spot. Monzo's ChatGPT mention rate improved from 22.7% to 24.2% (+1.5pp), and primary recommendation rate from 16.7% to 18.2% (+1.5pp). ChatGPT rewards consistent third-party citation presence and structured comparison content — both of which Monzo has maintained effectively. This is the template for what needs to work on Gemini and Claude.
Comparison query visibility has collapsed from 57% to 37.8% (-19pp). This is Monzo's strongest query category and its sharpest decline. Competitors are publishing more comparison-format content that AI platforms cite instead of — or alongside — Monzo's pages. The formats that drove Q2 performance are being eroded.
Informational query visibility fell from 5.1% to 2.6% (-2.5pp). This decline in informational visibility — the query type where users seek to understand banking products from scratch — means Monzo is increasingly absent from the awareness stage of AI-driven customer journeys.
Sector sentiment has uniformly flattened to neutral (5.0/10). In Q2, Starling scored 6.1 and Monzo 5.6. In Q3, every bank is at 5.0. AI assistants have moved from mildly endorsing challenger banks to providing balanced comparisons. No bank now receives positive sentiment — which means differentiation must come from presence and content quality, not AI advocacy.
All 20 zero-coverage gaps identified in April are still open in August. These are specific queries where competitors appear and Monzo does not. Four months is long enough for Revolut, Barclays and NatWest to have captured significant AI-driven customer consideration for each of these queries. Unclosed gaps compound over time.
The Revolut Threat
5.1 percentage points. Closing fast.
In April, Monzo led Revolut by 9.2pp. In August, that gap is 5.1pp. If this trend continues, Revolut overtakes Monzo in AI visibility by Q1 2027. This is not a forecast — it's a straight-line projection from two data points. Brands that monitor weekly can catch and reverse this before it becomes structural.
Platform-Level Trend — ChatGPT, Gemini, Claude
Platform divergence is the defining story of Q2–Q3 2026. Monzo moved in three different directions simultaneously: gaining on ChatGPT (+1.5pp), losing on Gemini (-7.5pp), and improving on Claude (+9.1pp, directional).
| Platform | Q2 Mention | Q3 Mention | Change | Q2 Primary | Q3 Primary | Change |
|---|---|---|---|---|---|---|
| ChatGPT | 22.7% | 24.2% | +1.5pp | 16.7% | 18.2% | +1.5pp |
| Gemini | 33.3% | 25.8% | −7.5pp | 25.8% | 19.7% | −6.1pp |
| Claude (directional) | 1.5% | 10.6% | +9.1pp | 1.5% | 4.5% | +3.0pp |

Claude data for August 2026 is based on a rerun of the original 66 queries after the initial run showed a high timeout rate. The successful rerun had a 70% completion rate. Claude data should be treated as directional rather than absolute.
Intent Trend — How Query Types Shifted Q2 to Q3
Every intent category declined for Monzo over the quarter. The most alarming drops are in comparison queries (-19pp), which had been Monzo's strongest category, and informational queries (-12pp).
| Intent Type | Q2 (April) | Q3 (August) | Q-on-Q Change | Q3 Status |
|---|---|---|---|---|
| Comparison | 57.0% | 37.8% | −19.2pp | Still strongest |
| Navigational | 38.0% | 25.6% | −12.4pp | Declining |
| Recommendation | 20.0% | 7.7% | −12.3pp | Weak |
| Transactional | 17.0% | 5.6% | −11.4pp | Weak |
| Informational | 5.1% | 2.6% | −2.5pp | Critical |

Pattern reading: The largest absolute declines are in comparison (-19pp) and navigational (-12pp) queries — Monzo's strongest categories — suggesting that these specific query types have become more competitive as other banks publish better comparison content. Informational and transactional declines suggest Monzo is also losing ground at the awareness and decision stages of the AI-driven customer journey.
Sentiment Trend — Sector Flattens to Neutral
AI assistants are no longer giving UK digital banks positive endorsements. Sentiment for all six brands converged to a uniform 5.0/10 neutral in Q3 — a flattening that affects Starling most sharply (down 1.1 points).
| Bank | Q2 Sentiment | Q3 Sentiment | Change | Q3 Category |
|---|---|---|---|---|
| Starling Bank | 6.1/10 | 5.0/10 | −1.1 (largest) | Neutral |
| Monzo | 5.6/10 | 5.0/10 | −0.6 | Neutral |
| NatWest | 5.4/10 | 5.0/10 | −0.4 | Neutral |
| Barclays | 5.3/10 | 5.0/10 | −0.3 | Neutral |
| Revolut | 5.3/10 | 5.0/10 | −0.3 | Neutral |
| Lloyds Bank | n/a | 5.0/10 | — | Neutral |

What neutralisation means strategically: When AI assistants endorsed Monzo mildly (5.6/10 in April), the tone of the response acted as an implicit recommendation. At 5.0/10, responses are balanced and comparative — presenting features and drawbacks side by side. This means brands can no longer rely on AI advocates; they must instead ensure their facts, features, and differentiators are accurately and completely represented in AI training data.
What Drove the Changes — Three Hypotheses
The Q2–Q3 divergence suggests three separate mechanisms at work simultaneously:
Hypothesis 1: Gemini changed how it weights UK financial content
Monzo's Gemini decline (-7.5pp) is too large to be explained by competitor content alone. Google updates Gemini's underlying retrieval and grounding continuously. Financial content may have been reweighted toward established-institution sources, regulatory filings, or fresh news content — all of which would disadvantage challenger banks relative to legacy banks and benefit Barclays and NatWest.
Hypothesis 2: Revolut published more Gemini-indexed comparison content
Revolut's SoV gain (+0.5pp) maps precisely to query categories where its international payments and FX content is strongest. This aligns with Revolut consistently publishing structured comparison and feature-comparison content at a higher cadence than Monzo in Q3.
Hypothesis 3: Claude's training data update excluded or de-emphasised challenger bank sources
Claude's model training is periodic, not continuous. A training data update between April and August may have de-emphasised sources (e.g., specific comparison sites, consumer finance publications) that previously gave Monzo visibility on Claude. With zero mentions in 198 queries, this cannot be a sampling artefact — it suggests a systematic absence in Claude's knowledge base.

Strategic Implications — What to Do in Q4
Priority 1: Emergency Claude visibility audit
Check robots.txt for ClaudeBot blocking. Audit whether citation sources Claude uses for banking content include Monzo. Create content specifically targeting Claude's training data signals — expert authorship, primary-source citations, structured FAQ data, long-form explainers on regulated financial topics.
Priority 2: Defend and extend ChatGPT performance
ChatGPT is the only platform where Monzo gained ground in Q3. The content strategy that's working there — third-party citation building, structured comparison content — should be extended to more query categories. Specifically: business banking, international payments, and savings queries where Monzo has low ChatGPT visibility.
Priority 3: Investigate and respond to Gemini decline
A 7.5pp drop on Gemini in one quarter needs investigation. Review what content Gemini is now citing for Monzo queries. Identify whether Revolut or Barclays content has displaced Monzo's content. Refresh or create content that matches the formats Gemini is now preferring — likely structured data-rich, regularly updated pages.
Priority 4: Close the 20 zero-coverage gaps
These gaps have been open for four months. Each one is a query category where Monzo is missing and a competitor is present. The formats needed are mostly comparison pages, use-case landing pages, and FAQ-schema-enriched explainers. These are table-stakes for recovery of informational and transactional visibility.
Priority 5: Weekly monitoring
Monthly analysis is too slow. The Q2–Q3 comparison shows 19pp of comparison query visibility was lost in four months without any point-in-time warning. Weekly AI Share of Voice monitoring would have caught the Gemini decline in June and flagged Claude's timeout issues in July — early enough to respond before the losses compounded.
