Workers Compensation Insurance: AI Market Discovery Index

Benchmark Summary

The Hartford led the Workers Compensation Insurance benchmark in September 2026 with valid recommendation coverage of 55.2%, down from 66.3% in July 2026. The gap to the next brand narrowed to 2.5 percentage points, with Travelers at 52.7% coverage in September 2026.

The largest coverage decline was The Hartford, falling to 55.2% in September 2026 from 66.3% in July 2026, a drop of 11.1 points. Liberty Mutual also declined significantly, to 29.1% in September 2026 from 39.3% in July 2026, a drop of 10.2 points. There were no significant coverage increases in the month.

Both declines came after an August 2026 peak or near-peak: The Hartford rose to 74.7% in August 2026 before falling back, while Liberty Mutual dropped to 24.4% in August 2026 and partially recovered in September 2026. The benchmark produced 203 qualified observations in September 2026, down from 211 in July 2026. Across the full series, the funnel began with 800 prompt-surface observations in each month and produced 203 qualified observations in September 2026 after qualification.

Current Benchmark at a Glance

Qualified surface breadth counts the six canonical AI/search surface families with at least one qualified observation: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode. Both months registered all six families. August 2026 also registered all six families, with 364 qualified observations, before the series contracted in September 2026.

Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design.

Brand-level percentages use the qualified observations as the public denominator, not the raw collection. Link AI Market Discovery Methodology.

Current Brand Standings

This table is the primary current-month benchmark view, sorted by valid recommendation coverage.

How to Read the Standings

Presence rate is the share of qualified observations where the brand appears in an AI answer, regardless of recommendation. Valid recommendation coverage is the share of qualified observations where the brand receives a clear recommendation. Top-three rate is the share where the brand appears in the top three recommended options. Rank-one rate is the share where the brand is the first recommendation. Net sentiment is the share of positive mentions minus negative mentions.

Recommendation Coverage Movement

Two brands tracked in August 2026 under alternative names, Hiscox and biBERK, are not directly comparable in this table; their naming reverted in September 2026 to Hiscox Usa and Biberk Business Insurance. In August 2026, Hiscox recorded 49.7% coverage and biBERK recorded 36.0% coverage; those figures carried the earlier brand names' presence rather than reflecting new market positions.

Largest Decline: The Hartford

The Hartford's valid recommendation coverage fell by 11.1 points to 55.2%, dropping sharply from its August 2026 peak of 74.7%. The brand's presence rate eased to 84.7% from 88.6%, top-three rate was 43.8% in September 2026 versus 46.0% in July 2026, and rank-one rate held near prior levels at 29.6%.

Largest Decline: Liberty Mutual

Liberty Mutual declined by 10.2 points to 29.1% valid recommendation coverage, after falling to 24.4% in August 2026, the brand partially recovered in September 2026. Presence rate was 66.0% in September 2026 versus 69.2% in July 2026, while top-three rate rose to 10.3% from 8.5%.

Category Leader: The Hartford

The Hartford remained the category leader in September 2026 with 55.2% valid recommendation coverage, though its lead narrowed substantially. The brand's rank-one rate of 29.6% in September 2026 remained the highest in the field, well ahead of Travelers at 8.9%.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. Top-three and rank-one rates reveal placement depth beyond whether a brand appears in a recommendation at all.

Chubb shows how close coverage can still hide very different first-position rates. At 46.8% coverage in September 2026, Chubb held a top-three rate of 18.2% but a rank-one rate of just 2.5%, while Travelers at 52.7% coverage reached a rank-one rate of 8.9%.

Buyer-Intent Distribution

All qualified observations in both months fell into the Brand Recommendation class, which covers discovery and consideration of specific insurers.

The current public series measures Brand Recommendation discovery only; pricing, value, and head-to-head comparison have no public signal in this data.

Historical Measurement Record

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment; it is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone. A single-month movement should not be treated as a confirmed trend.

About This Benchmark

The LLM Authority Index AI Market Discovery Index tracks how AI and search surfaces discover and recommend brands across industry categories.
