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. See the AI Visibility Market Discovery Methodology for details.

Current Brand Standings

Questions This Section Answers

• Which brands rank highest by valid recommendation coverage in October 2026?
• How does presence rate differ from valid recommendation coverage in the standings table?

How to Read the Standings

Presence rate is the share of qualified observations in which a brand appears in the AI response. Valid recommendation coverage is the share of qualified observations in which a brand receives a clear recommendation. Top-three rate is the share of qualified observations where a brand appears among the top three recommendations. Rank-one rate is the share where a brand is the first recommendation. Net sentiment reflects positive minus negative mentions where sentiment is exposed.

Recommendation Coverage Movement

Questions This Section Answers

• Which business checking brands saw the largest coverage gains since July 2026?
• Which brands experienced the sharpest coverage declines over the four-month series?
• How did Bluevine's coverage trajectory look across the measurement period?

Coverage movement across the four-month series was mixed. Eleven brands posted gains beyond normal variation since July 2026, and six posted declines beyond normal variation. Bank of America and U.S. Bank, which held the leading and second coverage positions in July 2026, both fell to no recorded coverage in October 2026.

Largest Increase: Mercury

Mercury recorded the largest valid recommendation coverage gain in the four-month series, rising to 48.5% in October 2026 from no recorded coverage in July 2026. Capital One posted the second-largest gain among brands entering the series, rising to 36.9% in October 2026 from no recorded coverage in July 2026. Among brands with July 2026 data, Relay posted the largest gain, rising to 44.2% in October 2026 from 20.4% in July 2026, a move of 23.8 points beyond normal variation. Axos Bank rose to 32.4% from 20.4% over the same period, a move of 12.0 points, and its coverage increased from 16.7% in September 2026 to 32.4% in October 2026, a move of 15.7 points beyond normal variation.

Largest Decline: Bank of America

Bank of America recorded the largest valid recommendation coverage decline in the four-month series, falling to no recorded coverage in October 2026 from 43.9% in July 2026. U.S. Bank fell to no recorded coverage in October 2026 from 40.2% in July 2026, and Wells Fargo fell to no recorded coverage in October 2026 from 31.8% in July 2026. U.S. Bank and Wells Fargo each declined in both of the two months since August 2026, while Bank of America's decline is concentrated in the most recent month, following two months of gains. Their companion entities, Bank of America Corp., U.S. Bancorp, and Wells Fargo & Co., entered the tracked set in October 2026 at 18.0%, 21.8%, and 11.1% respectively.

Category Leader: Bluevine

Bluevine led the benchmark with 53.2% valid recommendation coverage in October 2026, up from 43.1% in September 2026 and 30.3% in July 2026. The brand has held the coverage lead since entering the tracked set in July 2026, though its monthly trajectory has been uneven.

Recommendation Placement Snapshot

Questions This Section Answers

• Which brand has the strongest first-position recommendation rate in business checking?
• Why can two brands with similar coverage have very different rank-one rates?

Coverage alone does not show how prominently a brand is recommended. Bluevine and Mercury both ranked within the top tier for coverage in October 2026, while their first-position rates differed.

Coverage can look similar while first-position rates diverge sharply: Mercury and Relay both reached top-three placement rates above 24% in October 2026, yet each converted just 2.8% of observations into the first position, compared with 27.0% for Bluevine.

Buyer-Intent Distribution

All qualified observations in both July 2026 and October 2026 fell into the Brand Recommendation class.

The current public series measures the Brand Recommendation class of discovery and does not yet contain qualified observations in the Pricing & Value or Multi-Brand Comparison classes.

Historical Measurement Record

Questions This Section Answers

• Who has led the benchmark in each measurement period?
• How has the number of qualified observations shifted across the four months?

Each measurement is added to the same evergreen benchmark 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. Movement in a metric reflects a change in the benchmark; it does not by itself establish why the change occurred.

Top 10 Cited Domains

Questions This Section Answers

• Which domains are cited most often in AI responses about business checking accounts?
• Are citations concentrated among a few sources, or spread across many?

Across all AI platform responses in October 2026, the benchmark recorded 6,466 citations spanning 1,097 unique domains.

Citations are spread broadly across the information environment, with the top 10 domains accounting for a minority of total citations and more than a thousand unique domains appearing overall. Bluevine's own domain (bluevine.com) is the only tracked brand domain in the top 10, at rank nine with 100 citations. Review and comparison sites dominate the top of the list, led by nerdwallet.com and bankrate.com, alongside news outlets such as cnbc.com and forbes.com, community sources such as reddit.com and youtube.com, and industry sources such as airwallex.com.
