How AI Search Is Recommending Health Insurance: Monthly Trends

Executive Summary

Blue Cross Blue Shield ends October 2026 as the coverage leader in health insurance at 65.4% valid recommendation coverage, opening a 9.9-point lead over second-place Kaiser Permanente at 55.5%. That is a leadership position extended rather than merely held: since the July 2026 baseline, Blue Cross Blue Shield's coverage rose 7.6 points, a move outside the benchmark's normal range. Against the prior month alone, its coverage rose 12.8 points, also outside the normal range and the largest month-over-month gain recorded among brands tracked in both September and October 2026.

UnitedHealthcare Vision is the sharpest upward entrant, arriving at 46.3% coverage in October 2026 from no tracked coverage in July 2026, a 46.3-point move outside the normal range. Aetna Vision Preferred (34.0%), Humana Vision (27.3%), and UnitedHealthcare Vision together represent a newly qualified vision-insurance cohort inside the tracked universe, and all three post significant first-month coverage.

The sharpest decliner is Aetna, which fell from 45.8% coverage in July 2026 to 0.0% in October 2026, a 45.8-point decline outside the normal range and its second consecutive month of decline. Humana (41.9% to 0.0%) and UnitedHealthcare (53.9% to 0.0%) show the same pattern over the same window, each recording a three-month downward streak.

Against the prior month, the category was not stable: September 2026 to October 2026 produced a leadership position that widened, three legacy brands leaving the qualified recommendation set, and a new vision-focused cohort entering it. The July-to-October window therefore reads less as gradual drift and more as a re-composition of which brands the benchmark measures at all.

Each monthly run begins with 800 prompt-surface observations (552 unique questions in October 2026) across the benchmark's defined AI/search surface universe. Of those, 800 mentioned a tracked brand or competitor; 520 were relevant and 280 were irrelevant. The public metrics use the 488 observations that survive both qualification stages. In July 2026 the same funnel started with 800 observations (492 unique questions), of which 676 were relevant and 124 irrelevant, yielding 642 qualified observations. August 2026 produced 590 qualified observations from 582 unique questions, and September 2026 produced 553 from 565.

• Where did AI platforms conflict on Cigna's network status and Georgia marketplace availability?
• Which conflicting claims surfaced about Kaiser Permanente's and Oscar Health's cheapest plan pricing?
• Which specific price and tier details remained unresolved across platforms?

Five critical or high-severity factual inconsistencies were detected across six AI platforms.

Cigna

AI platforms provided conflicting information about Cigna's network status at a retail optical provider, rated high severity with 0.9 confidence. When asked "What insurance does ContactsDirect take?", Google AI Overviews stated that Cigna is listed under Out-of-Network and Other Plans, while ChatGPT stated that Cigna is listed among in-network plans. The Google AI Overviews response cited ContactsDirect's own vision insurance page, a Business Insider guide to buying contacts online with insurance, and ContactsDirect's customer service FAQ; the ChatGPT response cited only the ContactsDirect FAQ. A flagged source was the Business Insider guide, which the benchmark associated with the out-of-network side of the conflict, carrying an excerpt noting in-network plans alongside some out-of-network benefits for a list of carriers.

A second high-severity conflict, at 0.85 confidence, concerned Cigna's marketplace availability in Georgia. When asked "Which health insurance company is the best in Georgia?", Google AI Mode stated in the present tense that Cigna Healthcare offers individual and family health insurance plans in select Georgia counties, while Perplexity stated that Cigna marketplace plans are scheduled to end in Georgia after 2026, so members will need to choose another carrier. Google AI Mode referenced a LendingTree Georgia health insurance guide, a ForHealthInsurance Georgia comparison, and Anthem's Georgia individual and family page; Perplexity referenced Insure.com's best health insurance companies list, HealthInsurance.org's Georgia marketplace guide, and the federal plan information page for Georgia. A flagged source was Cigna's own Georgia shop-plans page, associated with the currently-available side of the conflict.

Responses differed on whether Cigna should be understood as an option a shopper can currently enroll in through the Georgia marketplace.

Kaiser Permanente

Two high-severity conflicts, each at 0.85 confidence, concerned which insurer is the cheapest individual option.

When asked "What is the cheapest and best health insurance?", Google AI Mode did not name Kaiser Permanente as the cheapest, listing Oscar Health and Ambetter as frequently the least expensive carriers for Bronze and Silver premiums and describing Kaiser only as best-rated overall for quality. Google AI Overviews, answering the same question, stated that Kaiser Permanente is the cheapest and best health insurance for individuals and has the lowest average rates for individuals. Google AI Mode referenced a YouTube video from iHealthBrokers and a Forbes advisor page on best affordable health insurance; Google AI Overviews referenced Investopedia's best affordable health insurance plans for 2026, a Covered California quote page, and a marketplace explainer. A flagged source on the Google AI Overviews side carried an excerpt describing Kaiser Permanente as "Best Overall, Most Affordable for Individuals."

The same question also produced a second conflict. Copilot stated that Kaiser Permanente's Bronze plan is the cheapest widely available health insurance in 2026 at around $463 per month, while Google AI Mode again did not name Kaiser as the cheapest and instead listed Oscar Health and Ambetter. Copilot referenced a CoveredUSA blog on cheapest health insurance options, a ValuePenguin cheap health insurance page, and a LendingTree best health insurance companies list. A flagged source on the Google AI Mode side carried an excerpt stating that the most affordable providers across all metal levels are Blue Cross Blue Shield, Anthem, Oscar, and Ambetter.

AI platforms therefore differ on whether Kaiser Permanente holds the lowest-price position at all, and on which carriers occupy that position if it does not.

Oscar Health

One high-severity conflict, at 0.9 confidence, concerned Oscar Health's cheapest plan monthly premium in Illinois. When asked "What's the cheapest health insurance in Illinois?", Gemini stated that Oscar's cheapest options are Gold-tier, with average monthly premiums around $563, while Copilot stated that Oscar's cheapest plan is a Bronze HMO at about $329 per month, with Silver averaging $563 per month. Gemini referenced the Get Covered Illinois marketplace, a MoneyGeek cheap health insurance Illinois page, and a ValuePenguin best cheap health insurance Illinois page; Copilot referenced the same MoneyGeek and ValuePenguin pages plus a CheapestACAplans Illinois page.

Flagged sources split across the conflict: a CheapestACAplans Illinois page on the Copilot side carried an excerpt listing a Bronze plan at $329 per month, while the MoneyGeek Illinois page on the Gemini side carried an excerpt stating that Oscar is Illinois's cheapest health insurance at $563 monthly. A third flagged source, a PolicyMage best health insurance in Illinois page on the Copilot side, listed a lowest available premium of $331.34 per month for a Bronze HMO.

The two platforms disagree on both the metal tier and the price point of Oscar Health's lowest-cost Illinois plan.

Benchmark Context

Questions This Section Answers

• How did the qualified observation base change between July and October 2026?
• What is the difference between the raw collection universe and the qualified analysis set?

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

The qualified observation count fell from 642 in July 2026 to 488 in October 2026 even as irrelevant prompts rose from 124 to 280, meaning every brand rate below is measured against a smaller and differently composed base than it was at baseline.

Benchmark-Level Metrics

August 2026 and September 2026 sat between these poles. August posted 590 qualified observations, a 34.2% recommendation-shaped answer share, and a 60.7% valid recommendation shortlist share; September posted 553 qualified observations, a 28.0% recommendation-shaped answer share, and a 57.5% valid recommendation shortlist share. The October figures reverse the shortlist share trend of the two prior months while continuing the decline in qualified observations.

AI Recommendation Trend

Questions This Section Answers

• Which brands gained or lost valid recommendation coverage between July and October 2026?
• Which brands' movements exceeded normal month-to-month variation?
• How did the vision-focused entrants change the ranking?

Coverage by Brand, July 2026 to October 2026

Ten brands exceeded normal month-to-month variation from July 2026 to October 2026: seven rose beyond the normal range — Blue Cross Blue Shield, Oscar Health, Molina Healthcare, Elevance Health, and the three vision-focused entrants — and three fell beyond it — Aetna, Humana, and UnitedHealthcare. The three brands carried as "not ranked" hold no valid recommendation coverage in the October qualified set; their July figures remain in the table as the baseline against which that absence is measured.

What Changed This Month

Questions This Section Answers

• Why did Blue Cross Blue Shield's coverage climb despite fewer valid recommendations?
• How did Kaiser Permanente lead rank-one recommendations while Blue Cross Blue Shield led total coverage?
• What separates the disappearing legacy brands from the newly qualified vision cohort?

Blue Cross Blue Shield

Blue Cross Blue Shield extended its category lead from 57.8% coverage in July 2026 to 65.4% in October 2026, a 7.6-point gain outside the normal range. The October figure also rose 12.8 points from the prior month, the sharpest single-month move in the field, after the brand had eased for two consecutive months into September 2026.

Its valid recommendation count fell from 371 in July 2026 to 319 in October 2026, even as the qualified base shrank from 642 to 488 observations — which is why its coverage rate climbed from 57.8% to 65.4% despite fewer valid recommendations in absolute terms. Its top-three rate climbed from 41.6% to 50.8%, a 9.2-point gain outside the normal range. Raw mention presence rose 6.1 points to 93.7%.

The distinction to notice: Blue Cross Blue Shield's lead now rests on broader shortlist inclusion rather than on first-position dominance. Its rank-one rate eased from 12.3% in July 2026 to 10.0% in October 2026, while Kaiser Permanente holds a rank-one rate of 40.0%. The brand is being named in more recommendation sets without being named first more often.

Highest-priority diagnostic: Which prompt types added Blue Cross Blue Shield to their shortlist between September and October 2026, and which of those place a different brand first?

Kaiser Permanente

Kaiser Permanente's coverage moved from 51.9% in July 2026 to 55.5% in October 2026, a 3.6-point gain inside the normal range, but the October figure rose 7.2 points from the prior month, a move outside the normal range.

Its rank-one rate rose from 33.0% to 40.0%, a 7.0-point gain outside the normal range, even though its rank-one count fell from 212 in July 2026 to 195 in October 2026 — the rate rose only because the qualified base shrank from 642 to 488 observations. Top-three rate rose 5.6 points to 47.5%. Raw mention presence held essentially flat, easing 1.1 points to 81.8%.

The distinction to notice: Kaiser Permanente converts shortlist presence into first-position recommendations at a materially higher rate than the coverage leader does. It holds the second-highest coverage in the field while holding the highest rank-one rate, a pairing that makes it the benchmark's strongest single-position performer even as Blue Cross Blue Shield leads on breadth.

Highest-priority diagnostic: Is Kaiser Permanente's rank-one lead consistent across all six AI surface families, or concentrated in the surfaces where it is also the named authority?

UnitedHealthcare Vision, Aetna Vision Preferred, and Humana Vision

UnitedHealthcare Vision entered the qualified set at 46.3% coverage in October 2026, from no tracked coverage in July 2026. Aetna Vision Preferred entered at 34.0% and Humana Vision at 27.3% over the same window. All three are significant risers by the benchmark's threshold.

UnitedHealthcare Vision recorded 226 valid recommendations, a top-three rate of 29.7%, and a rank-one rate of 11.7% in October 2026, with raw mention presence at 80.3%. Aetna Vision Preferred recorded 166 valid recommendations, a top-three rate of 8.6%, and no rank-one recommendations, with presence at 61.5%. Humana Vision recorded 133 valid recommendations, a top-three rate of 11.7%, and no rank-one recommendations, with presence at 51.6%.

The distinction to notice: these are first-month readings for brands that did not previously appear in the tracked roster, so their coverage figures carry no prior trend to compare against. UnitedHealthcare Vision arrives with the highest presence and rank-one rate of the three, but all three readings are single observations of a new cohort rather than evidence of a trajectory.

Highest-priority diagnostic: Which prompts surfaced the vision-focused brands, and whether those prompts also appear in the legacy medical-insurance cohort's question set.

Aetna, Humana, and UnitedHealthcare

Aetna fell from 45.8% coverage in July 2026 to 0.0% in October 2026, a 45.8-point decline outside the normal range and its second consecutive month of decline. Humana fell from 41.9% to 0.0%, a 41.9-point decline also outside the normal range, over a three-month downward streak. UnitedHealthcare fell from 53.9% to 0.0%, a 53.9-point decline outside the normal range, also over a three-month downward streak.

All three held substantial presence in July 2026: UnitedHealthcare at 96.3% raw mention presence, Aetna at 86.8%, and Humana at 75.5%. All three also held non-trivial placement in that month, with UnitedHealthcare at a 29.6% top-three rate and Aetna at 10.8%.

The distinction to notice: these brands have not disappeared from AI answers. They no longer hold valid recommendations within the October qualified set, which is a different measurement than presence. The benchmark records that they are absent from the recommendation stage, not that they are absent from the responses.

Highest-priority diagnostic: Whether these brands still appear in October responses without converting to recommendation credit, and which brands now occupy the recommendation slots they previously held.

Notable Divergence

The gap between UnitedHealthcare and UnitedHealthcare Vision widened every month of the July-to-October window, moving from 53.9 points in July 2026 to 46.3 points in favor of the vision-focused brand in October 2026, a swing of 100.2 points. The same pattern holds for Aetna against UnitedHealthcare Vision (a 92.1-point swing) and Humana against UnitedHealthcare Vision (an 88.2-point swing).

This is a category-level observation about how the benchmark's tracked universe now divides, not a statement about any one brand's performance. The legacy medical-insurance names and the vision-focused names are being recommended in different sets of answers, and the spacing between them widened in every month measured.

Buyer-Intent Interpretation

Questions This Section Answers

• Which buyer-intent clusters produced qualified observations in October 2026?
• What can the benchmark answer about pricing and head-to-head comparisons?

In October 2026, all qualified observations again fell into the brand recommendation class. The Pricing & Value and Multi-Brand Comparison classes carried zero qualified observations this month, as they did across the July-to-September window.

The public benchmark therefore cannot yet answer cost, value, or head-to-head comparison questions at the qualified level, even though the inconsistency data shows AI platforms making specific and conflicting price claims outside the qualified set. What the October data does answer is which single brand AI systems name as the best option, and that answer shifted materially toward Blue Cross Blue Shield and Kaiser Permanente while three legacy names dropped out of the recommendation stage.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations (query, surface, recommendation outcome, rank, sentiment, and citations where exposed). Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns. Source presence is not automatically treated as proof of causation.

Report-Specific Interpretation Notes

• Qualified observation counts declined through the window, from 642 in July 2026 to 488 in October 2026, even though the raw prompt total held at 800 each month.
• The number of prompts judged irrelevant rose from 124 in July 2026 to 280 in October 2026.
• Three vision-focused brands entered the tracked roster in October 2026 with no prior baseline; their coverage figures are single-month readings, not trends.
• Three legacy brands carry 0.0% coverage in October 2026 while holding substantial presence as recently as July 2026; recommendation coverage and raw mention presence are separate signals.
• Movement identifies changes worth investigating; it does not establish cause.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

Beneath the aggregate percentages sit the questions that matter most: which high-intent prompts a brand wins, which competitor is recorded with the recommendation when a brand loses it, what attributes AI systems associate with each option, and which external sources shape those answers. For the three brands now absent from the recommendation stage, the gap between continued presence in responses and the loss of recommendation credit points to a prompt-level pattern that aggregate data cannot explain. For the six brands that gained coverage, the same question applies in reverse.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It isolates which questions matter commercially, which surfaces carry the most influence, and where a brand's next recommendation gain is most likely to come from.
