How AI Search Is Recommending Professional Liability Insurance: Monthly Trends

Executive Summary

The Hartford remains the category leader in the September 2026 benchmark, but at 66.7% valid recommendation coverage it is down 10.5 points from the July baseline of 77.2% and down 16.1 points from August's 82.8%. The lead over the next brand, Next Insurance at 57.9% coverage, narrowed to 8.8 points from the 9.8-point gap recorded in August.

A notable naming pattern emerged this month: the brands previously tracked as Hiscox and biBERK do not appear in the September tracking universe, while two new entities, Hiscox Usa and Biberk Business Insurance, appeared and were immediately recommended at meaningful rates. Hiscox Usa recorded 38.8% coverage from 181 valid recommendations, and Biberk Business Insurance recorded 22.3% coverage from 104 valid recommendations. Hiscox had been tracked at 62.3% coverage in July and 59.6% in August; biBERK had been tracked at 35.0% in July and 39.0% in August. The simultaneous disappearance of the older names and appearance of the newer ones is consistent with a shift in how AI systems name these providers rather than a straightforward loss of visibility.

This was a mixed month for the category. Five tracked brands moved beyond their normal month-to-month range on the decline side: Next Insurance (down 12.6 points from the July baseline, down 15.1 points from August), Progressive Commercial (down 12.9 points from baseline, down 6.5 points from August), The Hartford (down 10.5 points from baseline, down 16.1 points from August), Hiscox, and biBERK. Two new entities, Hiscox Usa and Biberk Business Insurance, registered significant rises tied to their first appearance in the tracking universe. Several brands held steady, including Thimble, Travelers, Chubb, CNA, and Embroker.

Each monthly benchmark run begins with 800 prompt-surface observations across the defined AI/search surface universe (450 unique questions in July, 507 in August, 542 in September). All 800 prompts mentioned a tracked brand or competitor; 519 were relevant and 281 were irrelevant in July, 525 were relevant and 275 were irrelevant in August, and 493 were relevant and 307 were irrelevant in September. The public metrics use the 491 qualified observations from July, 493 from August, and 466 from September that survive both qualification stages.

Key Findings

Benchmark Context

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 491 in July to 466 in September, and the unique question count rose from 450 to 542 over the same period. August sat between the two, at 493 qualified observations and 507 unique questions.

Benchmark-Level Metrics

The recommendation-shaped answer share moved from 44.2% in July to 56.4% in August before settling at 39.5% in September. The valid recommendation shortlist share followed a similar path, rising to 81.9% in August before falling to 66.7% in September. These are shifts in the output distribution the benchmark observed; the data does not establish why the mix changed.

AI Recommendation Trend

Leaders Hold Their Ranks While Coverage Pulls Back Across the Category

Hiscox and biBERK, tracked separately in July and August, do not appear as named brands in September; Hiscox Usa and Biberk Business Insurance appear in their place at 3rd and 8th respectively. The three leading brands by coverage — The Hartford, Next Insurance, and Progressive Commercial — all declined beyond their normal month-to-month range, while the remaining tracked brands moved within a typical single-month range.

What Changed This Month

Hiscox and Hiscox Usa

Hiscox was tracked at 62.3% coverage in July and 59.6% in August before dropping out of the September tracking universe entirely. In its place, Hiscox Usa appeared in September at 38.8% coverage, drawn from 181 valid recommendations out of 466 qualified observations.

Hiscox Usa earned 102 top-three placements in September, a 21.9% top-three rate, and registered a 49.8% raw mention presence rate. For comparison, Hiscox in July had a 71.3% raw mention presence rate and 306 valid recommendations.

The pattern is consistent with AI systems now answering with the fuller Hiscox Usa name for prompts that previously returned the shorter Hiscox label. The benchmark records the naming shift without identifying whether the underlying prompts and visibility changed or only the surface label did.

Highest-priority diagnostic: Are the same prompt categories that returned Hiscox in July and August now returning Hiscox Usa, and does the recommendation depth match once the naming variants are reconciled?

biBERK and Biberk Business Insurance

biBERK fell from 35.0% coverage in July and 39.0% in August to 0.0% in September, a decline of 35.0 points from baseline that moved well beyond normal range. In the same month, Biberk Business Insurance appeared for the first time at 22.3% coverage.

Biberk Business Insurance drew 104 valid recommendations in September with a 28.3% raw mention presence rate. Its top-three rate was 6.7% and its rank-one rate 0.2%, meaning it was present and recommended but rarely placed at the top of AI answer lists.

biBERK's supporting signals in July included a 40.5% raw mention presence rate and a 12.0% top-three rate. The single-month drop and the simultaneous appearance of Biberk Business Insurance are consistent with a naming change in how AI systems identify the provider, not a category-wide exit.

Highest-priority diagnostic: Which specific prompts mention Biberk Business Insurance versus biBERK, and which surface families drove the new entity's 104 valid recommendations?

The Hartford

The Hartford's coverage fell from 77.2% in July and 82.8% in August to 66.7% in September, a decline of 10.5 points from baseline and 16.1 points from the immediately prior month. Both movements exceeded the brand's normal range.

Raw mention presence rose from 93.7% in July to 96.8% in September, meaning The Hartford remained present in nearly every answer. Its top-three rate fell from 60.3% to 53.4%, and its rank-one rate from 38.1% to 34.1%. The Hartford still earned 311 valid recommendations in September with 159 rank-one placements.

The Hartford remains the category leader, but the gap to Next Insurance narrowed from 9.8 points in August to 8.8 points. The combination of rising presence and falling recommendation depth suggests a shift in how often The Hartford is named versus placed at the top of AI shortlists.

Highest-priority diagnostic: Which prompt categories saw The Hartford fall out of the top recommendation position, and which brands took those placements?

Next Insurance

Next Insurance declined from 70.5% coverage in July and 73.0% in August to 57.9% in September, a drop of 12.6 points from baseline and 15.1 points from the prior month. Its top-three rate fell from 48.5% in July to 40.6% in September.

Raw mention presence held relatively steady at 77.9% versus 79.8% in July, and the rank-one rate declined from 18.7% to 15.9%. Next Insurance earned 270 valid recommendations in September with 74 rank-one placements.

The brand's presence held while its recommendation outcomes weakened, meaning AI systems continued to name Next Insurance but did so less often in recommendation-shaping positions. The decline in coverage coincided with the appearance of Hiscox Usa as a new tracked entity, but the data does not establish a direct transfer of recommendations.

Highest-priority diagnostic: Which comparison or recommendation prompts shifted away from Next Insurance, and did the new Hiscox Usa entity capture any of those placements?

Progressive Commercial

Progressive Commercial declined from 47.2% coverage in July to 34.3% in September, a drop of 12.9 points from baseline that exceeded normal range. The decline from August's 40.8% was 6.5 points.

The brand's top-three rate fell from 16.9% in July to 10.1% in September, and its rank-one rate from 3.5% to 1.3%. Raw mention presence held steady at 60.7% versus 60.5% in July, meaning the brand was still named in most answers but placed lower when recommended.

Progressive Commercial earned 160 valid recommendations in September with only 6 rank-one placements. The divergence between steady presence and falling recommendation depth is the signal most worth investigating.

Highest-priority diagnostic: Which prompt topics moved Progressive Commercial out of top-three placement, and which competitors captured those positions?

Buyer-Intent Interpretation

In September 2026, all 466 qualified observations fell into the Brand Recommendation cluster. The Pricing & Value and Multi-Brand Comparison clusters were empty, meaning the public benchmark cannot yet answer questions about how AI systems position brands on price or in direct comparison. The recommendation-shaped answer share declined to 39.5% from 56.4% in August, but the commercial comparison and pricing questions remain unanswered by this dataset.

Brand Opportunity Summary

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

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

• Naming variance: Hiscox and biBERK do not appear as tracked entities in September; Hiscox Usa and Biberk Business Insurance appear in their place. This may reflect changes in how AI systems name the providers, not changes in underlying visibility.
• Small-count movement: brand-level rates for Hiscox Usa (38.8%) and Biberk Business Insurance (22.3%) are drawn from first-month appearances; these should be read as early signals, not settled trends.
• Qualified denominator vs. raw collection: all percentage metrics use the 466 qualified observations in September, not the 800 raw prompt-surface observations. This excludes irrelevant and reserved prompts.
• Month-over-month movement identifies changes worth investigating; it does not by itself establish the cause of those changes.

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: which high-intent prompts is a brand winning, which competitor takes the recommendation when it loses, what attributes AI systems associate with each option, and which external sources shape those answers. The September naming shifts for Hiscox and biBERK add a layer of complexity: reconciling how AI systems label a brand is a prerequisite to reading its true position.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It can help clarify why coverage pulled back across the category, whether the Hiscox and biBERK naming shifts represent real changes in visibility or only in labeling, and what it would take for a specific brand to improve its position.
