The short version. UnitedHealthcare / AARP Medicare Plans does not have a visibility problem — it has the largest commercial mention share in the entire Q3 2026 study by a wide margin. Across 150 stratified queries and 14,405 populated responses, UnitedHealthcare recorded 10,838 scored commercial mentions, 18.35% of the 59,055-row baseline and more than double Aetna's share. It still ranks ninth of ten on QVI™ (34.91) among eligible brands with at least 100 mentions, and wins just 35.9% of its head-to-head comparisons against other carriers — second-to-last in the published matchup table. That is the analysis in two sentences.
Everything below is derived from the published Q3 2026 dataset. No proprietary instrumentation, no private access, no relationship with the company. The point of a public analysis is that a reader can check it, so every number here is reproducible from the open methodology linked at the end of the page.
Key takeaways
- UnitedHealthcare / AARP Medicare Plans recorded 10,838 scored commercial mentions — the largest in the 115-brand leaderboard, at 18.35% commercial share and 4.73% of all 229,372 extracted entity rows.
- It ranks ninth of ten eligible brands on QVI™ (34.91), behind brands with a small fraction of its mention volume — including Medicare.org, the QVI™ leader, on just 967 mentions.
- Its own-domain citation rate is 8.8% and its mention-to-citation authority ratio is 0.42 — it holds 18.35% of commercial mentions but only 7.7% of brand-owned citation rows.
- In 78 head-to-head comparison appearances against other carriers, UnitedHealthcare wins 28 (35.9%) — ahead of only SCAN Health Plan (6.2%) among the ten brands in the published matchup table.
1. The volume paradox
Commercial share is the most heavily reported reach measure in the benchmark: how much of the 59,055-row tracked-commercial baseline a brand holds. UnitedHealthcare is first on it, by a wide margin — 18.35% against Humana's 16.70% and Aetna's 15.42%, the next two closest competitors.
UnitedHealthcare finishes ninth of ten on QVI™.
Data table
| Brand (share rank) | Commercial share | QVI™ |
|---|---|---|
| 1. UnitedHealthcare / AARP Medicare | 18.35% | 34.91 |
| 2. Humana Medicare | 16.70% | 36.62 |
| 3. Aetna Medicare / CVS Health | 15.42% | 34.77 |
| 4. Blue Cross Blue Shield Medicare | 6.46% | 29.79 |
| 5. Cigna Healthcare Medicare | 6.01% | 21.56 |
| 6. Wellcare | 5.99% | 27.02 |
| 7. Anthem Blue Cross / Elevance Health | 2.98% | 28.00 |
| 8. Devoted Health | 2.62% | 29.57 |
| 9. Kaiser Permanente Medicare Advantage | 2.47% | 32.28 |
| 10. Medicare.org | 1.64% | 48.05 |
UnitedHealthcare's QVI™ rank is not an outlier within the top three reach leaders — Humana (36.62) and Aetna (34.77) also sit below several much smaller brands. But UnitedHealthcare's gap is the starkest in absolute terms: eleven times Medicare.org's mention volume, 13.14 points behind it on QVI™.
This is the same pattern Brainpan's Insurance AIVI™ found in Q2 2026 — State Farm led mentions and raw citations but was not the most-recommended brand in that study either. It is now confirmed across a second vertical with a different scoring model: QVI™ is deliberately volume-neutral, so reach and per-mention quality are reported, and should be read, separately.
2. What we measured, and what we did not
This section is deliberately placed before the analysis rather than after it.
- Public model outputs only. Every figure comes from scored commercial-brand mentions in responses generated by ChatGPT, Gemini, Claude, Perplexity, Google AI Overviews, Microsoft Copilot, and Bing Copilot. No advertising data, no analytics access, no internal reporting from UnitedHealthcare or AARP.
- No client relationship. Brainpan.AI has no commercial relationship with UnitedHealthcare. The company was not contacted, did not participate, and did not review this page. It appears here because it is the commercial-share leader in the Q3 2026 study, not because of any dispute or engagement.
- Row-based, not response-based. QVI™ and position scores are computed per scored row; a response can name a brand more than once, and repeated rows can occupy several positions. UnitedHealthcare's QVI™, mean recommendation score, own-domain citation rate, top-3 rate, and mean position score are computed on the scored subset of its rows (marked † on the full leaderboard); its mention count and commercial share reflect the complete dataset.
- A sample, not a census. One collection window, 2026-06-29 to 2026-07-03. Query sets, model versions, and retrieval behavior all move between quarters. Treat quarter-over-quarter movement as directional until a second cycle confirms it.
- Open methodology. The benchmark's scoring rules, study design, and correction policy are published and versioned. Reuse the findings, check them, disagree with them in public.
4. Second-to-last in head-to-head comparisons
The benchmark identifies 208 direct-comparison responses, where two or more carriers are weighed against each other in a single answer; 186 contain exactly two carrier brands. The higher Visibility Points total (the sum of position, recommendation, and citation scores) defines the scored winner within each pair.
| Brand | Pair appearances | Scored wins | Scored win rate |
|---|---|---|---|
| Alignment Health | 16 | 15 | 93.8% |
| Devoted Health | 21 | 18 | 85.7% |
| Kaiser Permanente Medicare Advantage | 20 | 17 | 85.0% |
| Blue Cross Blue Shield Medicare | 17 | 12 | 70.6% |
| Wellcare | 17 | 9 | 52.9% |
| Humana Medicare | 114 | 55 | 48.2% |
| Aetna Medicare / CVS Health | 55 | 24 | 43.6% |
| Cigna Healthcare Medicare | 18 | 7 | 38.9% |
| UnitedHealthcare / AARP Medicare | 78 | 28 | 35.9% |
| SCAN Health Plan | 16 | 1 | 6.2% |
UnitedHealthcare appears in the most head-to-head comparisons of any brand except Humana (78 against 114), which is itself a reach signal — it is named alongside a competitor often enough to be matched up repeatedly. But it converts those appearances into wins at the second-lowest rate in the published table. These outcomes do not necessarily represent explicit AI choices or beneficiary preferences, and opponent mix and sample size differ row to row; UnitedHealthcare's 78-appearance sample is large enough that the 35.9% figure is not a small-sample artifact the way Alignment Health's 16-appearance 93.8% might be.
5. Strategic diagnostic priorities
Three moves follow from the data above, stated as diagnostic direction rather than an execution plan — sequencing, prompt targets, and content specification depend on inputs no public dataset contains. The operating frameworks that carry that work are published in full at Brainpan.AI frameworks.
Stop treating mention volume as the constraint
UnitedHealthcare already holds the largest mention share in the study by a wide margin. A program that opens with increase AI visibility and measures itself on mentions is optimizing a variable already performing at the top of the category. The first question is not how to be named more often. It is what happens in the sentence after the name, and how the answer resolves when UnitedHealthcare is matched directly against a competitor.
Close the authority gap relative to Humana and Aetna
UnitedHealthcare's 0.42 authority ratio trails both Humana (0.71) and Aetna (0.78), the two carriers closest to it on reach. The gap is specifically in owned-domain citation, not overall quality — uhc.com supplies 1.74% of captured citations against an 18.35% mention share. Closing even half that gap would move UnitedHealthcare's authority ratio closer to its nearest reach competitors without any change in mention volume.
Investigate the head-to-head loss pattern
A 35.9% win rate across 78 comparisons, second-to-last among the ten brands reported, is a large enough sample to warrant inspecting the underlying responses directly — which competitors UnitedHealthcare is most often matched against, and whether losses cluster around specific query types or Position, Recommendation, or Citation Score components. The benchmark identifies the pattern; it does not diagnose the cause.
6. Data, method, and corrections
All figures are drawn from the Q3 2026 Medicare AIVI™ Benchmark, a study of 121 tracked Medicare brands (115 with recorded visibility) across 150 stratified queries and 14,405 populated responses on seven AI surfaces, producing 59,055 scored commercial mentions and 229,372 total extraction rows.
QVI™ (Quality Visibility Index) = 8 × mean Position Score + 7 × mean Recommendation Score + 25 × own-domain citation rate, scaled 0–100, computed on the subset of rows that received full per-mention scoring. The controlling rules behind every number above — study design, attribution, the QVI™ formula, and the known limitations — are published in the versioned Medicare AIVI™ methodology and correction policy.
If any figure on this page is wrong, we would like to know. Corrections go to kwalsh@brainpan.ai and are handled under the published correction policy — acknowledged in two business days, determined in ten, and applied to the page with a dated note rather than silently.
